total debt amounts to 80 of GDP Answer only the integer part If your result is 12345 your answer should be 123 The nominal GDP growth rate for the debt to remain stable is If the GDP grows by 2 the change in public debt that year will be Based on the previous items does a low economic growth rate result in an increasereduction in the debttoGDP ratio The Phillips Curve suggests an inverse longterm relationship between inflation and unemployment indicating that a higher inflation rate can be sustained with lower unemployment levels Supply shocks such as increases in oil prices can shift the Phillips Curve altering the relationship between inflation and unemployment According to the modern view of the Phillips Curve in the long run unemployment tends to converge to the natural rate regardless of the inflation rate Disinflation refers to a reduction in the inflation rate leading to a decline in absolute price levels In a specific sector of the economy firms identify the following relationship between the real wage w they pay and the total effort E exerted by workers given by the expression E 20w² 15w³ 500w Answer only the integer part If your result is 12345 your answer should be 123 The efficiency wage that firms in this sector are willing to pay is and the total effort E that workers deliver at the efficiency wage level is The Marginal Product of Labor MPL in this sector is given by MPL 15A Nd E2 and the level of productivity A is 8 The number of workers hired Nd in this sector is he quantity of labor supplied is given by the expression Ns w 20 The unemployment rate in this sector of the economy is The nominal exchange rate reflects the purchasing power of one currency relative to another adjusted for relative price levels between countries Disinflation has no economic costs as it reduces inflation without impacting growth or employment The monetary base consists only of cash in circulation held by the public excluding bank reserves or the required reserves mandated by the Central Bank An increase in public debt can lead to currency depreciation in the foreign exchange market especially if investors lose confidence in the countrys ability to meet its obligations Consider that the equations below describe a classical open economy for Brazil Desired consumption Cd 300 06Y 150r Desired investment Id 150 200r Government spending G 140 Net exports NX 200 02Y 05e Real exchange rate e 25 400r Full employment output Ȳ 1000 Provide only the integer part of your answers If your result is 12345 your answer should be 123 Calculate the equilibrium values of output real interest rate real exchange rate and net exports Consider a classical economy characterized by the following equations IS Curve r 8 0004Y LM Curve MP Y 120r πe ShortRun Aggregate Supply Curve Y Ȳ 250P Pe where r real interest rate πe expected inflation Ȳ potential output M nominal money supply P price level Pe expected price level Y current output Answer only the integer part If your result is 12345 your answer should be 123 For this question use inflation and and interest rate by its value in percentage not the decimal form Given that M 3100 πe 4 and Ȳ 1600 and the economy is in the full employment level the real interest rate is the output is and the price level is Now assume that the expected price level is the one found previously If the Central Bank unexpectedly reduces the nominal money supply to M 2900 in the short run the real interest rate now is the output is and the price level is The sacrifice ratio measures the cost in terms of lost output to reduce inflation by 1 percentage point Suppose an economy where the initial inflation rate is 8 per year and the government wants to reduce it to 4 after one year and the potential GDP Ȳ is 100 units Also The Phillips curve is given by π πe 08u 005 The expression for Okuns Law is Ȳ Y Ȳ 2u ū Answer only the integer part If your result is 12345 your answer should be 123 Based on this information the the total loss in GDP during the disinflation process was units Also the sacrifice ratio of this economy is In a Keynesian economy aggregate demand plays a central role in determining the level of output and employment especially in the short run The Keynesian approach emphasizes that monetary policy is the only effective tool to combat recessions as the rigidity of prices and wages prevents the automatic adjustment of the economy in the short run Nominal rigidity of prices and wages is irrelevant for explaining involuntary unemployment as the market always adjusts the supply and demand for labor automatically Menu costs are an explanation for price rigidity and refer to the financial and administrative costs that firms face when frequently changing the prices of their products The efficiency wage theory states that firms can pay wages above the market rate to increase worker productivity reduce turnover and improve the quality of work Consider an economy where the Central Bank follows the Taylor rule to determine the nominal interest rate i using the following formula i r π 05π πe 05y where r is the neutral real interest rate equal to 2 π is the current inflation rate equal to 4 π is the inflation target equal to 2 y is the output gap Y is the current GDP equal to 210 Ȳ is the potential GDP equal to 200 Answer only the integer part If your result is 12345 your answer should be 123 The nominal interest rate defined by the Central Bank is If there is no output gap then the nominal interest rate should be Evaluating the above items the larger the output gap the nominal interest rate should increasedecrease Therefore in recessions a raisecut in the interest rate is expected Consider an economy where The monetary base is 200 The currencytodeposit ratio is 03 The reservetodeposit ratio is 02 Answer only the integer part If your result is 12345 your answer should be 123 The money supply M in this economy is the amount of deposits in banks is the volume of currency in circulation is If the Central Bank reduces the monetary base to 180 keeping the ratios constant the new value of the money supply is Consider the following information for an economy The growth rate of the money is equal to the inflation rate The real demand for money can be obtained by L 100 02Y 500i The fullemployment output is Y 800 The real interest rate is r 002 Answer only the integer part If your result is 12345 your answer should be 123 The inflation rate that maximizes seignorage revenue is Thus the maximum seignorage revenue is 25112024 1510 Página 1 de 1
