Medieval Musical Instruments

Medieval Musical Instruments:How They've Changed Music is a very important part in many peoples lives. It is used in religious services, for peoples own satisfaction, for entertainment, and even for someones livelihood. Musical instruments were fully accepted into Western society around the year 900. Although musical styles have greatly changed throughout the ages, the instruments are still a very important part of peoples lives because music is beneficial to them. Music in the middle ages helped alleviate the drudgery of many peoples lives. People would get together and play in small instrumental ensembles. Or they would get their own instrument out at the end of a long day and relax with the latest dance tune. There are several different types of musical instruments. Many of these were invented or perfected in the middle ages. Some wind instruments are: the shawm, cornetto, gemshorn, serpent, early trumpet, and the sackbut. Their modern counterparts are: oboe, recorder, flute, tuba, modern trumpet, and the trombone. There were also many string instruments in the Middle Ages including the psaltery, dulcimer, and the lute. Some of these instruments are still around today in different forms such as the harpsichord, newer dulcimer, and the modern guitar. Man discovered in the early days that he could produce a sound by blowing across the end of a tube. As the pipe got longer, the pitch got lower (Remnant 113). This discovery led to the woodwind instruments invented in the Middle Ages. The shawm was the early oboe. It was a long, straight wooden instrument with a bell, played with a double reed. It had keys covering the holes that the player could use to make different tones. The cornetto was similar to the modern recorder. It was made out of wood. In the early fourteenth century, it had with seven finger holes (Baker 1). A third woodwind instrument was the gemshorn. This instrument ...

Hook the Mouse to Catch Events Outside an Application

Hook the Mouse to Catch Events Outside an Application Learn how to track the mouse activity even when your Delphi application is not active, sits in the tray or does not have any UI at all. By installing a system-wide (or global) mouse hook you can monitor what the user is doing with the mouse and act accordingly. What Is a Hook and How Does It Work? In short, a hook is a (callback) function you can create as part of a DLL (dynamic link library) or your application to monitor the goings on inside the Windows operating system.There are 2 types of hooks - global and local. A local hook monitors things happening only for a specific program (or thread). A global hook monitors the entire system (all threads). To create a global hook you need 2 projects, 1 to make the executable file and 1 to make a DLL containing the hook procedure. Our article on working with keyboard hooks from Delphi explains how to intercept the keyboard input for controls that cannot receive the input focus (like TImage). Hooking the Mouse By design, the movement of the mouse is restricted by the size of your desktop screen (including the Windows Task Bar). When you move the mouse to the left/right/top/bottom edge, the mouse will stop - as expected (if you do not have more that one monitor). Heres an idea for the system-wide mouse hook: If for example, you want to move the mouse to the right side of the screen when it moves toward the left edge (and touches it), you might write a global mouse hook to reposition the mouse pointer. You start by creating a dynamic link library project. The DLL should export two methods: HookMouse and UnHookMouse. The HookMouse procedure calls the SetWindowsHookEx API passing the WH_MOUSE for the first parameter - thus installing a hook procedure that monitors mouse messages. One of the parameters to the SetWindowsHookEx is your callback function Windows will call when there is a mouse message to be processed: SetWindowsHookEx(WH_MOUSE, HookProc, HInstance,0) ; The last parameter (value 0) in the SetWindowsHookEx defines we are registering a global hook. The HookProc parses the mouse related messages and sends a custom message (MouseHookMessage) to our test project: function HookProc(nCode: Integer; MsgID: WParam; Data: LParam): LResult; stdcall;var   Ã‚   mousePoint: TPoint;   Ã‚   notifyTestForm : boolean;   Ã‚   MouseDirection : TMouseDirection; begin   Ã‚   mousePoint : PMouseHookStruct(Data)^.pt;   Ã‚   notifyTestForm : false;   Ã‚   if (mousePoint.X 0) then   Ã‚   begin   Ã‚  Ã‚  Ã‚   Windows.SetCursorPos(-2 Screen.Width, mousePoint.y) ;   Ã‚  Ã‚  Ã‚   notifyTestForm : true;   Ã‚  Ã‚  Ã‚   MouseDirection : mdRight;   Ã‚   end;....  Ã‚   if notifyTestForm then   Ã‚   begin   Ã‚  Ã‚  Ã‚   PostMessage(FindWindow(TMainHookTestForm, nil), MouseHookMessage, MsgID, Integer(MouseDirection)) ;   Ã‚   end;  Ã‚   Result : CallNextHookEx(Hook,nCode,MsgID,Data) ;end; Tip: Read the Win32 SDK Help files to find out about the PMouseHookStruct record and the signature of the HookProc function. Note: A hook function does not need to send anything anywhere - the PostMessage call is used only to indicate that the DLL can communicate with the outer world. Mouse Hook "Listener" The MouseHookMessage message is posted to your test project - a form named TMainHookTestForm. Youll override the WndProc method to get the message and act as needed: procedure TMainHookTestForm.WndProc(var Message: TMessage) ;begin   Ã‚   inherited WndProc(Message) ;  Ã‚   if Message.Msg HookCommon.MouseHookMessage then   Ã‚   begin   Ã‚  Ã‚  Ã‚   //implementation found in the accompanying code   Ã‚  Ã‚  Ã‚   Signal(TMouseDirection(Message.LParam)) ;   Ã‚   end;end; Of course, when the form is created (OnCreate) you call the HookMouse procedure from the DLL, when it gets closed (OnDestroy) you call the UnHookMouse procedure. Note: Hooks tend to slow down the system because they increase the amount of processing the system must perform for each message. You should install a hook only when necessary, and remove it as soon as possible.

Fish oil Assignment Example | Topics and Well Written Essays - 500 words

Fish oil - Assignment Example This effect is achievable when fish oil is consumed with amino acids. Another benefit of fish oil is that it enhances the immunity by supporting the white blood cell activity (Sears, 2014). It also enhances insulin sensitivity in muscles and promotes the delivery of nutrients across the cell membrane. Furthermore, it is beneficial in acceleration of metabolism and reduction of triglyceride levels. Ultimately, omega-3 plays a crucial role in brain development, especially in babies and recent research shows that it is beneficial in treating cognitive conditions, dementia as well as Alzheimer’s disease (Sears, 2014). The digestion of fish oil occurs in the small intestines through the process of hydrolysis by the pancreatic lipase and bile salts to produce two fatty acids and a monoglyceride that are absorbed in the intestines and reassembled to triglycerides (Maroon, 2006). The triglycerides are transported into lymphatic channels and later into the blood stream by chylomicrons (Maroon, 2006). Bioavailability refers to the ability of the ingestible capsule of omega 3 fatty acids to be absorbed by the body into the bloodstream, tissues and organs. Bioavailability is important because it determines the amount of capsule to be ingested for proper effect on the body (Wexler, 2007). Research demonstrates that the most bio available fish oil is that with the re-esterified triglyceride form. Ingestion of omega-3 supplements is more effective after a meal as compared to ingestion on an empty stomach (Wexler, 2007). The risk of heart diseases is best prevented by lowering the levels of low-density lipoproteins (LDLS) and blood cholesterol and increasing high-density lipoproteins (HDLs) in the blood. Eskimos diet consists largely of fatty fish. It is noteworthy that obesity in this community is prevalent (Luten, 2006). Recent studies conducted on sardines and salmons, which are their main food revealed that, albeit their heavy weights,

W4 Essay Example | Topics and Well Written Essays - 1000 words

W4 - Essay Example Oral communication has an advantage of receiving feedback immediately. It is the most appropriate method of communication for effective discussions. The feedback takes a longer period of time to be received in written communication (Keyton & Shockley-Zalabak, 2009). In oral communication, information is obtained first hand from the speaker and therefore there is no possibility of distortion of facts. Moreover, the points that are not clear can be explained by the speaker especially due to the fact that communication is shared between him/her and the audience. Gestures and facial expressions can be used to enhance the clarity of information. However, there are several weaknesses in oral communication. In contrast to written communication, the speaker and the audience must be present for communication to be achieved. The advantage of written communication is that messages can be conveyed in the absence of the audience to be read later. It also enhances remembrance since the information can be referred from time to time, which may not be possible for information communicated orally. There is usually a coherent flow of ideas while writing, some of which might be forgotten in oral communication. On the other hand, written communication allows the de livery of substantial information, which may be difficult through oral communication. However, unlike oral communication, literacy is paramount for effective communication; hence it might not be applicable for the illiterate people. Communication through notices in the workplace allows all workers an opportunity to view information posted on a common place. This is more effective than oral communication whereby some employees may not receive clear information especially if they were absent at the time of the announcement (Shockley-Zalabak, 2005). Leadership communication is significant for the accomplishment of the goals of leadership. Oral and written communications allow

Quality Control Department Essay Example for Free

Quality Control Department Essay In an attempt to cut costs in the Quality Control Department of XYZ Deli, it is important to first identify the costs to determine which aspects of the company’s quality control process can be eliminated, if any at all. Quality control costs can be divided into three different classifications. These classifications are prevention costs, appraisal costs and failure costs (Stevenson, 2008). Prevention costs are costs generated in the process of impeding product mistakes or flaws in order to supply customers with XYZ Deli brand quality products or to improve current products. Prevention costs are the most indispensable of the quality control costs. It is less expensive and much less difficult to repair a flaw or defect before the product reaches the customer. Prevention costs include not only planning and administrative procedure costs, but also education/training and increased equipment maintenance costs. It is important that all employees are trained accurately throughout the quality control process in order to produce XYZ Deli quality products and to ensure a decline in the possibility of erroneous design and productivity (Stevenson, 2008). Possible tradeoffs for this cost would be if employees are not trained properly, ensuring the job is being done correctly; may result in the production of unsatisfactory product. This could potentially create loss of sales or opportunity costs because the products are being poorly produced. However, increasing the time spent training employees could delay the production process. This would also create opportunity costs because the product would take longer to get  to the customer. While prevention costs are most vital, appraisal costs are necessary to ensure customers are being provided with the high quality products expected from the XYZ Deli brand. This would include costs of inspection of products to determine if product standards and parameters are being met, as well as to detect any product flaws. An example of appraisal costs is inspection costs. Inspection costs are incurred during the quality testing process. This includes the cost of the inspection facility and inspector auditor salaries, as well as any materials, appliances or tools used to test XYZ Deli brand products (Stevenson, 2008). A potential tradeoff to not inspecting product could also allow defective product to reach the customer, creating opportunity costs. Poorly produced products will not be well received. At any rate, the tradeoff for properly inspecting all the product being produced could set back the time it takes for the product to reach the market; also creating opportunity costs. Finally, failure costs are generated when components of the product or the product itself is faulty. Failure costs can be either internal or external. Internal failures are those detected in one of the production phases; before the product reaches the customer. There are numerous issues that contribute to an internal failure; such issues include: faulty materials received, improper handling of material, defective equipment, and improper use of equipment. Examples of internal failure costs are loss of production time, worthless material and the cost of regenerating previous work and/or the rebuilding of the product, as well as the cost of inspecting the reworked product. Other examples of internal failures include possible damage to equipment; possible safety issues causing employee injuries. External failures are failures that are identified after the customer has received the product. Such issues are not discovered during production or inspection process. These costs are much more expensive and much more difficult to correct because the product has already reached the consumer. Examples of a failure costs include managing customer complaints, accountability and possible litigation. Overseeing warranty issues, providing replacements and payments are also examples of failure costs. An  important failure costs to avoid is the loss of customer loyalty (Stevenson, 2008). Not only does XYZ Deli want to recruit new customers, it is important to retain current valued customers. Not finding a way to take care of the consumer may give the company a poor reputation, creating more opportunity costs. While each of these costs is expensive, they are necessary in maintaining the reputation of a growing company, such as XYZ Deli. Prevention appraisal costs are the preferable way to disperse funds because they prevent failure costs. Failure costs are much more expensive for the company, not only in terms of money, but also in terms of the company’s reputation, good will and the ability to retain current valued customers. If XYZ Deli spends the time and money on the appropriate such as ensuring proper training in production and inspection, the company will save money in the future. References Stevenson, W. (2008).

ESSAY ON 3 WAR POEMS -- English Literature

ESSAY ON 3 WAR POEMS No man wants to go to war and no government wants war but there are many different circumstances that lead to the action of war. Those involved in war will have political and personal views towards it. The First World War was greeted with great enthusiasm and patriotism; however it was the war in which millions died compared to the wars after. In the past 200 years warfare has changed and with this change the ideas on war have changed too. Wilfred Owen, Rudyard Kipling and David Roberts are well known war poets. Using a selection of their poems we hope to analyze the two conflicting views on war. To understand what influenced the poets we need to get an idea of their social and historical background. The poet Rudyard Kipling was an ex army official so his poems on war can be trusted. However during Kipling’s war days war was not fully mechanized so Kipling cannot really describe the horror of WW1. In his poem ‘For All We Have and Are’ Rudyard Kipling uses words and phrases like â€Å"For all our children’s fate† to emphasize the need for war, Saying if you are not going to fight for yourself than fight for your children. He than justifies going to war by saying â€Å"a crazed and driven foe†. I think by this he means that our foe is mentally disturbed we have to stop him for his own and others benefit. He than says â€Å"The Hun is at the gate† Meaning that the Germans are coming. If we don’t go out and meet them they will attack us. He also curses the Germans by calling them Huns. The Huns were originally an ancient tribe who ravaged and plundered every where they went. By calling the Germans, Huns Rudyard Kipling suggests that they are the same and present a danger to all so we hav... ... the stupidity of the war and uses sarcastic phrases such as ‘It must take guts to drop those bombs on defenceless people who had no chance’ to emphasize the unfairness of the war. Roberts also says ‘Your boys didn’t have to maim and kill or break the hearts of other mothers’ by this statement I think he means that I know your depressed about the loss of your sons but think of the other mothers whose hearts your sons broke by killing people who like them were just following orders. In this poem I feel David Roberts challenges the government’s decision to go to war against Iraq by calling this war the ‘shamefullest of wars’ and by highlighting the depression and death it has already caused. If you look at the differences between the 3 poems described you will find that as time want on and war got uglier you started hearing more of the truth about war.

Give a brief definition of fiscal policy? What are its economic goals? Fiscal policy is the use of the federal budget to achieve full employment, control inflation, and stimulate economic growth. The changes to the federal budget can be made through increases or decreases in government spending or through increases or decreases in tax revenues. [text: E p. 214; MA p. 214]. 2. What is the Council of Economic Advisers?The Council of Economic Advisors is responsible f or assisting and advising the president on economic affairs. One of its principal responsibilities is to prepare an annual report for the president that is submitted to Congress that describes the state of the economy and recommends economic policies to achieve full employment, control inflation, and encourage economic growth. [text: E pp. 214-215; MA pp. 214-215]. 3. â€Å"The Employment Act of 1946 is no more than a vague and ill-defined commitment by the Federal government to assist in the achievement of full employment. Do you agree? Explain. To agree with this statement does not diminish the importance of the Employment Act of 1946. The Constitution has also been called vague and ill-defined, but that does not diminish its importance. This act committed the Federal government to following policies which would attempt to stabilize prices and promote full employment and established the CEA and JEC to assist in this task. While specific policies were not outlined, the intention o f the act is clear it is a responsibility of the Federal government to assist in this effort.That had not been an explicit on-going policy before 1946. [text: E p. 214; MA p. 214] 4. Explain the effect of a discretionary cut in taxes of $40 billion on the economy when the economy’s marginal propensity to consume is . 75. By how much is output likely to expand if the economy is operating in the horizontal range of its aggregate supply curve and there are no complications to this fiscal policy? How does this discretionary fiscal policy differ from a discretionary increase in government spending of $40 billion? If MPC is . 75, the multiplier is 4.A tax cut of $40 billion will result in initial increase in consumption of $30 billion (. 75 ? $40 billion). This initial increase in spending will ultimately result in an increase in consumption spending of $120 billion because of the multiplier process. In contrast, an initial increase in government spending of $40 billion will ultima tely increase consumer spending by $160 billion (4 ? $40) because none of the initial increase is siphoned off as savings as would be the case with a $40 billion tax cut. [text: E pp. 215-216; MA pp. 215-216] 5.Explain the effect of a discretionary increase in government spending of $50 billion on the economy when the economy’s marginal propensity to consume is . 75. By how much is output likely to expand if the economy is operating in the horizontal range of its aggregate supply curve and there are no complications to this fiscal policy? If MPC is . 75, the multiplier is 4. An initial increase of $50 billion government spending will result in a total increase in output of $200 billion. [text: E pp. 215-216; MA pp. 215-216] 6. Explain the aspects of expansionary and contractionary fiscal policy.During which phases of the business cycle would each be appropriate? 201 Chapter 12 Expansionary fiscal policy refers to increases in government spending or decreases in taxes or both, so that the net effect on aggregate demand is an increase in net government spending. Contractionary fiscal policy is the opposite: an increase in taxes or decrease in government spending or both, so that the net effect on aggregate demand is a decrease in net government spending. Expansionary policy would most likely be used during a recession (or trough) phase.A contractionary policy would most likely be employed near the peak of the business cycle as the economy reaches full-employment GDP and the potential for inflation accelerates. [text: E pp. 215-217; MA pp. 215-217] 7. Differentiate between discretionary fiscal policy and nondiscretionary or built-in stabilization policy. Discretionary fiscal policy is the deliberate manipulation of taxes and government spending by the Congress to alter real domestic output and employment, to control inflation, and to stimulate economic growth during a particular period of time.Nondiscretionary fiscal policy, on the other hand, is the chang e in government expenditures or taxes which occurs automatically as a result of existing laws. In particular, personal income taxes have progressive rates and will slow spending and inflation as GDP expands; when GDP declines, taxes will decrease by a more than proportionate amount allowing incomes and spending to decline at a slower rate than GDP. There are also many transfer payment programs which become effective when incomes decline or unemployment occurs to reduce the decline in disposable income.Conversely, these programs automatically are reduced when the economy expands and unemployment declines and spending increases. [text: E pp. 215, 219-220; MA pp. 215, 219-220] 8. Describe two ways the Federal government can finance a deficit and explain which would have the more expansionary effect. The government can borrow money from the private sector in which case it will be competing with private business borrowers for funds. If planned investment spending is â€Å"crowded out,â €  the impact of expansionary deficits will be offset by the decline in investment spending.The government can also finance a deficit by issuing new money which essentially means that the Federal Reserve has financed the deficit. This type of financing would be more expansionary than borrowing from the private sector. [text: E pp. 217-218; MA pp. 217-218] 9. Describe two ways the Federal government could retire debt in the event of a budget surplus and explain which would have the most contractionary impact. The government could use a budget surplus to pay off existing debt which would â€Å"recycle† funds back into the economy and potentially offset the decline in government spending.Alternatively, the government could impound the surplus funds, or allow them to stand idle, which means these funds are not injected into the economy and would have a more contractionary effect than the first alternative. [text: E p. 218; MA p. 218] 10. What is the anti-inflationary or contra ctionary effect of a budget surplus? The anti-inflation effect of a budget surplus depends on what the government does with the surplus. The budget surpluses may be used for debt reduction. In this case, bonds 202 Fiscal Policy are bought back by the government and money is pumped back into the economy.Interest rate will tend to fall, and this may increase consumer and investment spending, thus offsetting some of the contractionary effect of the budget surplus. The government may also impound funds (not spend them). This action will be more contractionary because it actually removes spending from the economy that would have been spent otherwise. [text: E p. 218; MA p. 218] 11. Explain how a small budget surplus could actually be somewhat expansionary rather than contractionary. This could be the unlikely result of what the government decides to do with the surplus.If it is used to retire existing debt, then the surplus is pumped right back into the economy and with the multiplier ef fect this additional liquid wealth in the hands of individuals could lead to an increase in aggregate demand and GDP. [text: E p. 218; MA p. 218] New 12. Comment on the statement: â€Å"Increasing government spending is preferred to a cut in taxes when the U. S. government seeks to fight a recession. † The statement is a normative one. Either action, increased government spending or taxation, can be use to fight a recession. The policy choice will depend on the preferences of the individual.Those individuals who want to fight a recession with an increase in government spending may want to preserve the size of government in the economy and have specific government programs they would like to see funded. Those individuals who prefer a tax cut may want to reduce the size of government and give people more money and the freedom to spend it as they chose. [text: E p. 218; MA p. 218] 13. Explain what is meant by a built-in stabilizer and give two examples. Built-in stabilizers are changes in tax revenues or government spending which occur automatically during different phases of the business cycle.For example, the progressive income tax will dampen any expansion of aggregate demand in the recovery peak phases; and will dampen any decline in income and aggregate demand during a recession as taxes are automatically reduced by a greater proportion than the decline in personal income. There are also government spending programs which increase during recessionary periods automatically as incomes decline or are lost. The so-called â€Å"safety net† programs include unemployment compensation, welfare programs, and food stamp spending.These spending programs are automatically reduced during a recovery peak phase which would dampen aggregate demand and inflationary pressures automatically. [text: E pp. 218-219; MA pp. 218-219] 14. â€Å"The more progressive a tax system, the greater is the economy’s built-in stability. † Explain this statement for both recessionary and peak phases of the business cycle. A progressive tax would take a progressively greater proportion of rising incomes during the peak phase of the business cycle which means it would dampen spending increases and aggregate demand which, in turn, reduces inflationary pressures.On the other hand, a progressive tax would take proportionately less away from declining incomes during a recessionary phase allowing disposable income to fall less rapidly than real GDP. Therefore, aggregate demand would decline less rapidly than GDP and the magnitude of the spending decline that might occur in the absence of the tax would be reduced. [text: E pp. 219-220; MA pp. 219-220] 203 Chapter 12 15. Explain how the below graph illustrates the built-in stability of a progressive tax structure. The graph illustrates how net taxes are negative as GDP declines which will add to aggregate demand.When GDP expands, tax revenues increase which dampens aggregate demand. [text: E pp. 219-22 0; MA pp. 219-220] 16. In Year 1, the full-employment budget showed a deficit of about $100 billion and the actual budget showed a deficit of $150 billion one year. In Year 2, the full employment budget showed a deficit of about $125 billion and the actual budget showed a deficit of $150 billion. Based on these data, what can be concluded about the direction of fiscal policy? Fiscal policy was expansionary because the full-employment budget deficit increased from one year to the next.The actual deficit is composed of the full-employment portion and the cyclical portion. The full-employment portion of the actual budget deficit rose from $100 to $150 billion. The cyclical portion is determined by taking the actual deficit and subtracting the cyclical portion from it. The cyclical portion of the actual deficit fell from $50 billion to $25 billion. The actual budget deficit did not change, but it does not provide a good indication of the direction of fiscal policy. Only the full-employm ent budget tells the direction of fiscal policy. text: E pp. 220-221; MA pp. 220-221] 17. What is the difference between the actual deficit, the full-employment deficit, and the cyclical deficit? The actual budget deficit for any year consists of the full-employment and the cyclical deficit. The full-employment deficit is the difference between government expenditures and tax collections which would occur if there were full employment output. The cyclical deficit is the portion of the actual deficit that arises because the economy is in recession and is produced by this downturn in the business cycle.During a recession, a cyclical deficit often occurs because tax revenues fall as incomes fall and government expenditures increase as more is spent for government transfer payments and other programs. The cyclical deficit occurs because of the operation of these automatic stabilizers. [text: E pp. 221-222; MA pp. 221-222] 18. What does the â€Å"full-employment budget† measure an d of what significance is this concept? The full-employment budget refers to the budget deficit or surplus that would result with existing tax and spending programs if the economy were operating at full-employment.In other words, tax revenues and government spending are estimated at the level that would result if full employment existed. 204 Fiscal Policy Some economists believe that the full-employment budgetary deficit or surplus is what should determine the expansionary or contractionary nature of fiscal policy rather than the actual budgetary deficit or surplus. If the full-employment budget is not in deficit, then expansionary fiscal policy is not being followed according to this view even if the actual budget is in deficit. text: E pp. 221-222; MA pp. 221-222] 19.

Why is this difference significant? The spending-taxation decisions of government are made in a political environment in which the majority must be satisfied, or satisfied enough to continue to vote for its elected representatives. Furthermore, since the government does not have a limited lifespan and always has the ability to tax, deficit-spending and debt do not have the same significance to governments that they do to individual households.Households face a much more uncertain future with regar d to their power to raise revenue (income) and therefore must plan their spending and saving to coincide with their lifetime earnings expectations. The difference is significant because so many people try to draw an analogy between government spending policies and household spending plans when it is usually not appropriate to do so. [text: E pp. 223-224; MA pp. 223-224] New 21. Comment on the statement: â€Å"Discretionary fiscal policy offers an ideal approach to dealing with the nation’s economic problems. It is without problems, criticisms, or complications. Discretionary fiscal policy does offer government policymakers potential tools (changing taxes or government spending) to use for stimulating the economy during a recession or for contracting the economy during a period of high inflation. Fiscal policy, however, is not without its problems, criticisms, or complications. First, there are timing problems in getting it implemented at the right time so it will be effectiv e. Second, there are political problems in getting it accepted because it takes time to get the actions passed through Congress and signed by the President.Third, there are expectations problems because policies may be reversed in the future. Fourth, the taxing and spending decisions of the Federal government may be partially offset by the taxing and spending decisions of state and local governments. Fifth, some economists are concerned that expansionary fiscal policy that requires the Federal government to borrow money will raise interest rates and crowd out investment spending, thus reducing 205 Chapter 12 the expansionary effect of the fiscal policy. Sixth, there are complications arising from the connection of the domestic economy to the world economy.Aggregate demand shocks from abroad or a net export effect may increase or decrease the effectiveness of a given fiscal policy. [text: E pp. 223-225; MA pp. 223-225] New 22. Explain the six problems, criticisms, or complications th at arise in the implementation of fiscal policy. First there is a timing problem. Three lags are identified under the â€Å"timing problem† category. There is a lag in recognizing the phase of the business cycle; there is an administrative lag in deciding which policies to follow; there is an operational lag in terms of the impact of the policy once it is implemented.Second, there are political considerations in the adoption of fiscal policy. There is some evidence of a political business cycle where particular expansionary policies are followed in election years whether or not economic conditions merit them. Third, there is an expectations complication. If businesses and households expect that the fiscal policy will be reversed in the future, they may not change their behavior in the way that would be expected if the fiscal policy was permanent.Fourth, the taxing and spending decisions of state and local governments may counteract or reduce the effectiveness of fiscal policy decisions at the federal level. The U. S. government may enact an expansionary fiscal policy by increasing its budget deficit, but state and local governments often have to balance a budget and economic conditions may force them to adopt a contractionary policy that partially offset what the federal government is seeking to achieve.Fifth, there is concern about possible offsetting effects of government borrowing crowding out private spending that would occur in the absence of the government deficit; and an offsetting net export effect which partly counteracts expansionary policy or contractionary policy. Sixth, there are complications to domestic fiscal policy from the national economy’s connection to the world economy. Economic shock from abroad can have an effect on the nation’s imports and exports. The net export effect can reduce the intended effects of fiscal policy. text: E pp. 223-226; MA pp. 223-226] New 23. Explain the problems giving rise to this statement: â€Å"You would think the government would want to do something to improve economic conditions when the economy is in trouble, but the government is slow to act. † Fiscal policy is subject to timing problems. There are three timing lags that limit the speed with which fiscal policy can be enacted and effective. First, there is a lag in recognizing the phase of the business cycle to determine when the government might want to provide help.Second, there is an administrative lag in decision-making that involves deciding which specific policies should be adopted. Third, there is an operational lag because the adoption of policies takes time to have an effect on output and employment. [text: E p. 223; MA p. 223] New 24. How do expectations about the future by households and businesses affect the effectiveness of fiscal policy? Cite examples. If households or businesses expect that the fiscal policy changes are only temporary, they may not change their behavior in the expected way. For example, if tax cuts are enacted to stimulate consumer spending, some consumers may not change their 206 Fiscal Policy spending habits if they think the tax change is only temporary. In the future, they will have to pay more in taxes, so they might increase their saving. Similarly, businesses may not invest in new plants and equipment if they get a tax cut, if they expect taxes in the future to rise or the fiscal policy to be ineffective.

Exact forecasting, if possible, would still not solve all of the problems encountered in trying to correct the business cycle. There is also the problem of timing the enactment and application of fiscal policy, not to mention the coordination of monetary policy and international economic policies, or reduced private spending (â€Å"crowding out†). [text: E pp. 223-225; MA pp. 223-225] 26. Explain the crowding-out effect. The crowding-out effect is the notion that government borrowing to finance a deficit may crowd out or reduce private borrowing.To the extent that this occurs, the expansionary impact of fiscal policy is reduced because increased demand by the government is partially offset by reduced demand in private investment. [text: E pp. 224-225; MA pp. 224-225] 27. Using the below graph, illustrate the possible impact of a crowding-out effect of a fiscal policy by drawing in the relevant aggregate demand shifts. Label and explain any shifts in the demand curve shown. Expansionary fiscal policy increases demand from AD1 to AD2, but this crowds out some private investment spending that offsets the increase to some extent causing AD2 to decrease to AD3.See graph below. [text: E pp. 224-225; MA pp. 224-225] 28. Explain how the net-export effect would reduce the effectiveness of fiscal policy. 207 Chapter 12 If an expansionary fiscal pol icy brings with it higher interest rates, this could increase the demand for American dollars by foreign investors seeking to earn the higher U. S. returns. This appreciation of the dollar makes U. S. goods and services more expensive to foreigners and foreign imports less expensive to Americans. The net export category of ggregate demand will be reduced which would reduce the impact of expansionary fiscal policy. A contractionary fiscal policy could have the opposite effect causing net exports to increase that again reduces the desired effect of the contractionary fiscal policy. [text: E pp. 225-226; MA pp. 225-226] New 29. What fiscal policy is most likely to be invoked during a period of recession and high unemployment? A period of rapid inflation? What political, investment, and international problems might the U. S. Congress encounter in enacting these policies and putting them into effect?During recession and high unemployment, the government would most likely initiate an expa nsionary fiscal policy. A contractionary fiscal policy would most likely be called for during a period of rapid inflation, especially if it seems to be demand-pull inflation. Several problems are likely to arise in enacting either of these policies. Timing lags in recognition, implementation, and impact are one concern. Another has to do with political realities. A contractionary policy has many unpopular aspects to it because it calls for raising taxes and for cutting government spending.There are also unique problems associated with expansionary policy: crowding out is one potential result that would reduce the expansionary effect of the policy. In both cases, the net-export part of aggregate demand is likely to move in a direction that would tend to offset the policy. [text: E pp. 223-226; MA pp. 223-226] 30. (Last Word) What is the purpose of the Conference Board’s index of leading economic indicators? The index of leading indicators is a monthly index of economic statist ics that are used to forecast the direction of real GDP.Changes in the index provide an indication of the future direction of the economy and are useful to policy makers in developing responses to deteriorating conditions in the economy. The rule of thumb is that three successive decreases or increases in the index indicate a change of direction in the economy. [text: E p. 227; MA p. 227] 31. (Last Word) Why is the index of leading economic indicators a composite index of ten economic statistics and not just one? Each of the economic statistics used to prepare the index may increase or decrease in any month and thus give false or contradictory signals about the direction of the economy.It is less likely that all these economic indicators, taken together, will give as many false signals about the direction of the economy as one indicator will. Thus the composite index is more reliable than any one indicator. The composite index, however, is not infallible and can also give false indi cations about the direction of the economy because of changes in the structure of the economy or developments that are not covered by the indicators that make up the index.
