IGNOU BECC-116 Previous Year Solved Question Paper in English

Q1. In an open economy with floating exchange rate, analyze the effectiveness of fiscal policy and monetary policy.

Ans. The Mundell-Fleming model (or the IS-LM-BP model) is the standard framework for analyzing the effectiveness of fiscal and monetary policy in an open economy with a floating exchange rate. This model assumes perfect capital mobility , meaning the country’s interest rate (r) is pegged to the world interest rate (r ). In a floating exchange rate system, the exchange rate (e) is determined by supply and demand in the foreign exchange market. Effectiveness of Fiscal Policy: An expansionary fiscal policy (e.g., an increase in government spending or a cut in taxes) shifts the IS curve to the right, putting upward pressure on income (Y) and the interest rate (r). As the domestic interest rate rises above the world interest rate (r > r ), it attracts a massive inflow of foreign capital. This inflow of capital increases the demand for the domestic currency, causing the currency to appreciate . The appreciation of the currency makes the country’s exports more expensive and imports cheaper, leading to a fall in net exports (NX). This fall in net exports acts as a drag on the economy, shifting the IS curve back to the left, all the way to its original position. Consequently, the level of income and output remains unchanged. The only final effects are a change in the composition of output (more government spending, less net exports) and a higher exchange rate. Thus, under floating exchange rates, fiscal policy is completely ineffective at influencing output. Effectiveness of Monetary Policy: An expansionary monetary policy (e.g., an increase in the money supply) shifts the LM curve to the right. This causes the domestic interest rate (r) to fall below the world interest rate (r ). The lower interest rate leads to a massive capital outflow as investors seek higher returns abroad. This outflow of capital increases the demand for foreign currency, causing the domestic currency to depreciate . The depreciation of the currency makes the country’s exports cheaper and imports more expensive, leading to a rise in net exports (NX). This increase in net exports boosts aggregate demand and shifts the IS curve to the right. This process continues until the IS curve intersects the new LM curve at a point where r = r . The final equilibrium is at a much higher level of output (Y), with the interest rate remaining at the world level. Thus, under floating exchange rates, monetary policy is highly effective at influencing the level of output and income. Conclusion: In an open economy with a floating exchange rate and perfect capital mobility, the Mundell-Fleming model concludes that monetary policy is a powerful tool for controlling real output, while fiscal policy becomes ineffective.

Q2. Explain how the Aggregate Demand (AD) curve can be derived. Describe the factors that explain the slope and the position of the AD curve.

Ans. The Aggregate Demand (AD) curve illustrates the relationship between the overall price level (P) and the total quantity of goods and services demanded in an economy (Y). It is derived from the IS-LM model, which shows equilibrium in the goods market (IS curve) and the money market (LM curve). Derivation of the AD Curve: 1. Start with an initial equilibrium in the IS-LM model (Y₀, r₀) for a given price level, P₀. The LM curve’s position depends on the real money supply (M/P₀). 2. Now, assume the price level increases to P₁ (P₁ > P₀). This reduces the real money supply (M/P₁) since the nominal money supply (M) is held constant. 3. A decrease in the real money supply shifts the LM curve to the left (or upwards). 4. With the IS curve unchanged, this leftward shift of the LM curve results in a new equilibrium with a higher interest rate (r₁ > r₀) and a lower level of output (Y₁ < Y₀). The higher interest rate discourages investment, thereby reducing aggregate demand. 5. We now plot these two combinations of price and output, (P₀, Y₀) and (P₁, Y₁), on a separate graph with the price level (P) on the vertical axis and output (Y) on the horizontal axis. Connecting these points gives us a downward-sloping AD curve. Slope of the AD Curve: The AD curve slopes downward, indicating an inverse relationship between the price level and aggregate demand. This is due to three main effects:

• Real Balance Effect (Pigou Effect): A higher price level reduces the real value (purchasing power) of money holdings. This makes people feel poorer and reduce their consumption, thus decreasing aggregate demand.
• Interest Rate Effect (Keynes Effect): As explained in the derivation, a higher price level reduces the real money supply, which increases interest rates. Higher interest rates reduce investment and consumption spending, leading to lower aggregate demand.
• Exchange Rate Effect (Mundell-Fleming Effect): A higher price level increases interest rates, which attracts foreign capital, leading to an appreciation of the currency. A stronger currency reduces net exports (exports fall, imports rise), thereby decreasing aggregate demand.

Position (Shifters) of the AD Curve:

The position of the AD curve is determined by any factor that shifts the IS or LM curves for a given price level.

• Factors Shifting the IS Curve: Changes in fiscal policy shift the AD curve.
  • An increase in government spending (G) or a decrease in taxes (T) shifts the IS curve to the right, which in turn shifts the AD curve to the right.
  • An increase in consumer and firm confidence, leading to higher autonomous consumption or investment, also shifts the AD curve to the right.
• Factors Shifting the LM Curve: Changes in monetary policy shift the AD curve.
  • An increase in the money supply (M) shifts the LM curve to the right, increasing output at any given price level and thus shifting the AD curve to the right. Conversely, a decrease in the money supply would shift the AD curve to the left.

Q3. What type of inconsistency is observed in cross-sectional and time series of data on consumption? Explain how the permanent income hypothesis reconciles it.

Ans. When studying the relationship between consumption and income, economists observed a significant inconsistency between findings from cross-sectional data and time-series data. This empirical puzzle is known as the Kuznets’ Puzzle . The Nature of the Inconsistency: 1. Cross-sectional Data: Surveys of households at a single point in time revealed that as income rises, the proportion of income spent on consumption, known as the Average Propensity to Consume (APC) , tends to fall. This means high-income households save a larger fraction of their income. This suggests a non-proportional consumption function (C = C₀ + cY), where APC = C/Y = C₀/Y + c, which decreases as Y increases. 2. Time-series Data:

• Long-run Time-series: Studies of aggregate income and consumption data over long periods (many decades) showed that the APC was remarkably stable. The consumption function appeared to be proportional (C = kY), passing through the origin, implying consumption is a constant fraction of income.
• Short-run Time-series: Studies over business cycles found that the APC falls during booms and rises during recessions, a finding similar to the cross-sectional results.

The puzzle is: why does the APC fall with income in cross-sectional and short-run studies, but remain constant in the long run?

Reconciliation by the Permanent Income Hypothesis (PIH):

The

Permanent Income Hypothesis

, developed by Milton Friedman, offers a compelling resolution to this inconsistency.

Core Idea:

The PIH argues that an individual’s consumption does not depend on their current income (Y) but on their

permanent income (Yp)

. Permanent income is the average, long-run income an individual expects to receive over their lifetime. The consumption function is C = αYp, where α is a constant fraction of permanent income.

Friedman divided current income (Y) into two components:

• Permanent Income (Yp): The expected average income.
• Transitory Income (Yt): The random or unexpected deviation from permanent income, which can be positive (e.g., a bonus) or negative (e.g., a temporary layoff). So, Y = Yp + Yt.

Reconciling the Puzzle:

• Explaining Cross-sectional Data: In a cross-sectional sample, a group of high-current-income individuals will, on average, contain people with positive transitory income (Yt > 0). Similarly, a low-current-income group will have people with negative transitory income (Yt < 0). Since people consume based on their permanent income (Yp), the high-income group will be spending a smaller fraction of their current income (a lower APC = C/Y), while the low-income group will be spending a larger fraction of their current income, or even dissaving (a higher APC). This explains the falling APC in cross-sectional data.
• Explaining Time-series Data: In the long run, positive and negative transitory income components tend to cancel each other out, making average transitory income zero. Therefore, over the long run, average current income equals average permanent income (Y ≈ Yp). The consumption-income ratio then becomes C/Y ≈ αYp/Yp = α, which is a constant. This explains the stable APC observed in long-run time-series data.

Thus, the PIH resolves the puzzle by showing that short-run and cross-sectional relationships are biased by transitory income components, while the long-run relationship reflects the stable underlying pattern of permanent income.

Q4. Why is debt stabilization important for an economy? On the basis of government budget constraint, explain how debt-to-GDP ratio can be maintained.

Ans. Debt stabilization refers to the situation where a government’s debt-to-GDP ratio does not grow uncontrollably but instead follows a stable or declining path. It is critically important for macroeconomic stability and long-term growth of an economy. Importance of Debt Stabilization:

1. Fiscal Sustainability: It prevents a “debt spiral,” where rising debt leads to higher interest payments, which in turn increase the deficit and debt further. A sustainable debt level ensures the government can meet its obligations in the future without a crisis.
2. Crowding Out Private Investment: High and rising government debt increases the demand for loanable funds, which can drive up interest rates. Higher interest rates discourage private investment (crowding out), slowing long-term economic growth.
3. Risk of Inflation: If a government finances its deficits by printing new money (monetizing the debt), it can lead to high inflation, which erodes the value of the currency and savings.
4. Threat of Financial Crisis: A very high debt-to-GDP ratio can erode investor confidence. If investors start to believe the government may default, they will demand higher interest rates or stop lending altogether, potentially triggering a sovereign debt crisis.
5. Intergenerational Equity: Unchecked debt passes the burden of repayment, in the form of future taxes, onto future generations who must pay for the spending of the current generation.

Government Budget Constraint and Stabilizing the Debt-to-GDP Ratio:

The dynamics of the debt-to-GDP ratio are understood through the Government Budget Constraint. The constraint can be written as:

ΔB = (G – T) + rB

Here, ΔB is the change in the stock of debt, (G – T) is the primary deficit (spending excluding interest payments minus revenues), r is the real interest rate, and B is the initial stock of debt.

To express this as a ratio of GDP (Y), we get the following equation for the change in the debt-to-GDP ratio (b = B/Y):

Δb = (G – T)/Y + (r – g)b

Here, g is the growth rate of real GDP. The term (r – g)b is called the “snowball effect”; it shows how the debt ratio can grow on its own if the interest rate exceeds the economic growth rate.

To maintain (stabilize) the debt-to-GDP ratio, we must have Δb = 0.

This implies:

(G – T)/Y = – (r – g)b

Or,

(T – G)/Y = (r – g)b

This equation provides the key condition for debt stabilization. (T – G)/Y is the

Primary Surplus

(as a share of GDP).

• If r > g : The interest rate is higher than the growth rate, so the debt ratio has a natural tendency to increase. To stabilize it, the government must run a primary surplus equal to (r – g)b. The higher the initial debt (b), the larger the required primary surplus.
• If r < g : The economic growth rate is higher than the interest rate. In this favorable scenario, the debt ratio tends to fall on its own. The government can run a small primary deficit and still maintain a stable debt ratio.

Thus, to maintain the debt-to-GDP ratio, policymakers must manage the primary balance (the gap between G and T) in a way that offsets the effect of the initial debt level and the differential between the interest rate and the growth rate.

Q5. How do you reconcile the vertical long-run Phillips curve with a downward-sloping short-run Phillips curve? Explain through a diagram.

Ans. The Short-Run Phillips Curve (SRPC) shows an inverse relationship or trade-off between inflation and unemployment. It implies that policymakers can achieve lower unemployment by accepting higher inflation. This curve is downward-sloping. In contrast, the Long-Run Phillips Curve (LRPC) is a vertical line at the Natural Rate of Unemployment (u ) . This implies that in the long run, there is no trade-off between inflation and unemployment. The economy will always return to its natural rate of unemployment, regardless of the rate of inflation. The reconciliation of these two seemingly contradictory views is achieved through the Expectations-Augmented Phillips Curve , which highlights the crucial role of inflationary expectations . The Reconciliation Process: The short-run Phillips curve is drawn for a given level of expected inflation (πe). When people’s expectations change, the entire SRPC shifts. Let’s explain this with a diagram: 1. Assume the economy is initially at point A, where unemployment is at its natural rate (u ) and actual inflation is equal to expected inflation (π₀). This is on SRPC₀. 2. Now, the government uses an expansionary policy (e.g., monetary expansion) to reduce unemployment from u to u₁. The economy moves up along SRPC₀ to point B. At this point, unemployment is lower (u₁), but inflation has unexpectedly risen to π₁. 3. At point B, actual inflation (π₁) is higher than what was expected (π₀). Workers and firms notice this “inflation surprise” and revise their expectations for future inflation upwards to π₁. 4. As expected inflation rises to π₁, the entire short-run Phillips curve shifts upwards to SRPC₁. Now, if the government tries to maintain unemployment at u₁, it will have to generate even higher inflation. If not, the economy will revert to the natural rate u , but now at a higher stable inflation rate of π₁ (point C). 5. The Long-Run Phillips Curve (LRPC) connects all the points (like A and C) where actual inflation equals expected inflation and unemployment is at its natural rate. It shows that any attempt to permanently hold unemployment below u* will only lead to accelerating inflation, with no long-run reduction in unemployment. Thus, the downward-sloping SRPC is a short-term phenomenon that exists when expectations are fixed. Once expectations adjust to actual inflation, the trade-off disappears, and we are back on the vertical LRPC.

Q6. Bring out the salient features of the monetary approach to exchange rate determination.

Ans. The Monetary Approach to exchange rate determination is a theory which posits that, in the long run, the exchange rate is determined by the relative supply of and demand for the two countries’ monies. It is essentially an open-economy version of the Quantity Theory of Money, viewing the exchange rate as the relative price of two national monies. Its salient features are as follows:

1. Based on Purchasing Power Parity (PPP): The approach assumes that PPP holds in the long run, meaning the exchange rate adjusts to equalize price levels across two countries. The equation is P = E P , where P is the domestic price level, P is the foreign price level, and E is the nominal exchange rate. This yields E = P/P .
2. Money Market Equilibrium: It assumes that money markets are in equilibrium in both countries. For the domestic money market, M = P L(Y, i), and for the foreign market, M = P L (Y , i*), where M is money supply, L is money demand, Y is real income, and i is the interest rate.
3. Exchange Rate Determination: By combining these equations, the monetary approach arrives at the formula: E = (M/M ) [L (Y , i ) / L(Y, i)] This equation shows that the exchange rate is a function of the relative money supply (M/M ) and relative money demand (L*/L).
4. Key Implications:
   • Money Supply: Ceteris paribus, an increase in the domestic money supply (M) will cause a proportional depreciation of the domestic currency (E rises). Conversely, an increase in the foreign money supply (M*) will cause an appreciation of the domestic currency (E falls).
   • Real Income: An increase in domestic real income (Y) raises the demand for money, causing the domestic price level to fall and the domestic currency to appreciate (E falls).
   • Interest Rates: An increase in domestic interest rates (i) raises the opportunity cost of holding money, reducing money demand. This leads to a higher domestic price level and a depreciation of the domestic currency (E rises).
5. Long-Run Perspective: As it relies on long-run equilibrium conditions like PPP, the monetary approach is primarily considered a model of the long-run behavior of the exchange rate, not its short-run fluctuations.

Q7. Describe the major components of the Balance of Payments (BoP). Explain why the BoP always balances.

Ans. The Balance of Payments (BoP) is a systematic record of all economic transactions between the residents of a country and the rest of the world over a specific period (usually a year). Major Components of the BoP: The BoP is mainly divided into three accounts:

1. Current Account: This records the flow of goods, services, income, and current transfers.
   • Trade in Goods: Involves exports (credit) and imports (debit) of merchandise. Also known as the Balance of Trade.
   • Trade in Services: Includes exports and imports of services like tourism, transport, software, banking, etc.
   • Income: Comprises income from investments (e.g., profits, dividends, interest) and compensation of employees.
   • Current Transfers: These are one-way payments with nothing received in return, such as gifts, grants, and remittances.
2. Capital Account: This records two main items: (i) capital transfers, such as debt forgiveness, and (ii) the acquisition/disposal of non-produced, non-financial assets (like patents, copyrights). It is usually a small component.
3. Financial Account: This records transactions involving financial assets and liabilities.
   • Direct Investment (FDI): Long-term investment that gives significant influence over an enterprise.
   • Portfolio Investment: Trade in securities like stocks and bonds.
   • Other Investment: Includes loans, trade credits, and currency and deposits.
   • Reserve Assets: Shows the change in the central bank’s holdings of foreign currency reserves.

Why the BoP Always Balances:

The BoP always “balances” because it is constructed based on the principle of

double-entry bookkeeping

. Under this system, every economic transaction has two sides: a credit (+) and a debit (-), and they are always equal.

• A credit (+) entry is a transaction that leads to a receipt of foreign currency (e.g., exporting goods).
• A debit (-) entry is a transaction that leads to a payment of foreign currency (e.g., importing services).

For example, when India exports software worth $100 to the US, it is recorded as a credit entry of $100 in the current account. The $100 received as payment increases the foreign currency assets held by Indian banks, which is recorded as a debit entry of $100 in the financial account. Thus, (+100) + (-100) = 0, and the account balances.

In theory,

Current Account + Capital Account + Financial Account = 0

.

In practice, due to difficulties in data collection, a discrepancy arises, which is adjusted by a balancing item called

“Errors and Omissions”

. So the practical identity is:

Current Account + Capital Account + Financial Account + Errors & Omissions = 0.

A “BoP deficit” or “surplus” in common parlance usually refers to the balance on the current and capital accounts combined, which is offset by official reserve transactions.

Q8. What is meant by rational expectations? What are its implications?

Ans. Rational expectations , a theory pioneered by John Muth and developed by Robert Lucas and Thomas Sargent, posits that individuals, when forming their expectations about the future, use all available and relevant information . This includes not just knowledge of past events, but also an understanding of how the economy works (economic models) and what the government’s likely policies will be. The core idea is that people do not make systematic or predictable errors. While their forecasts can be wrong, the errors are random and average to zero over time. This stands in contrast to adaptive expectations, where people form expectations based only on past experiences. Implications of Rational Expectations:

1. Policy Ineffectiveness Proposition: According to Sargent and Wallace, if expectations are rational and prices and wages are flexible, then systematic and predictable macroeconomic policies (like a known rule for monetary expansion) are ineffective in influencing real variables like output and unemployment, even in the short run. People anticipate the policy, adjust their prices and wages immediately, and the policy only affects the price level (inflation), not real output.
2. Effectiveness of Unanticipated Policy: Only unanticipated or surprise policy actions can have real effects in the short run because they cause people’s expectations to be temporarily wrong.
3. The Lucas Critique: This argues that traditional econometric models used for policy evaluation are unreliable. When a new policy is introduced, people’s expectations and behavior change, which in turn changes the underlying structure (the parameters) of the model. Therefore, using a model estimated on old data to predict the effect of a new policy is invalid.
4. “Cold Turkey” Disinflation: Disinflation (reducing inflation) can be achieved with little or no cost in terms of lost output, provided the central bank’s announcement of the new, tougher policy is credible. If people believe the announcement, they will immediately lower their inflation expectations, short-circuiting the painful Phillips curve trade-off.

Q9. State the reasons behind exchange rate overshooting.

Ans. The exchange rate overshooting hypothesis, developed by Rudiger Dornbusch in 1976, explains the high volatility of floating exchange rates. It states that following a monetary shock, the nominal exchange rate will initially move beyond its long-run equilibrium level (i.e., “overshoot”) before gradually returning towards that equilibrium. The fundamental reason for overshooting is the difference in the speed of adjustment between asset markets and goods markets . Key Reasons and Mechanism:

1. Sticky Prices: The key assumption in the Dornbusch model is that in the short run, the prices of goods and services are “sticky”—they adjust slowly. They do not change instantly due to contracts, menu costs, etc.
2. Fast-Adjusting Asset Markets: In contrast, financial asset markets, including those for exchange rates and interest rates, adjust almost instantaneously. They react rapidly to new information.
3. The Mechanism Explained:
   • Suppose the central bank unexpectedly increases the money supply.
   • Immediate Effect: The excess supply in the money market causes the domestic interest rate to fall instantly.
   • Uncovered Interest Parity (UIP): For the UIP condition (i ≈ i* + expected change in exchange rate) to hold, if the domestic interest rate (i) has fallen, there must be an expectation of a future appreciation of the domestic currency to induce investors to hold domestic assets.
   • Overshooting: For the currency to be expected to appreciate in the future, it must first depreciate by more than its new, long-run equilibrium level. Therefore, the exchange rate immediately plummets (depreciates) sharply. This initial large depreciation is the “overshooting.”
   • Long-Run Adjustment: Over time, the sticky goods prices start to rise. As prices rise, the real money supply falls, pushing the interest rate back up. As the interest rate rises, the exchange rate gradually appreciates back towards its new, weaker long-run equilibrium level.

In short, sticky goods prices force the entire burden of short-run adjustment onto the fast-moving exchange rate, causing it to over-react and overshoot its long-run target.

Q10. Describe a loss function. Explain how the shape of the loss function changes according to the perception of the central bank.

Ans. A loss function is a mathematical expression used in economics, particularly in the context of monetary policy, to represent how much a central bank dislikes deviations from its policy objectives. It formalizes the trade-offs a policymaker faces. A typical central bank loss function might take the form: L = (y – y )² + β(π – π )² Where:

• L is the total loss the central bank seeks to minimize.
• y is actual output and y* is target output (often potential output).
• π is the actual inflation rate and π* is the target inflation rate.
• β (beta) is a crucial parameter representing the relative weight the central bank places on inflation stabilization versus output stabilization.

The squared terms imply that the central bank dislikes deviations from the target in either direction, and larger deviations are disproportionately more costly.

Shape of the Loss Function and Central Bank Perception:

The “shape” of the loss function, often visualized as indifference curves in output-inflation space, changes according to the central bank’s preferences or “perceptions,” as captured by the parameter

β

.

1.

High β (“Inflation Hawk”):

If a central bank places a very high weight on inflation stability (β is large), it is known as a “hawk” or a conservative central bank. Its loss function indifference curves will be relatively

flat

. This means the bank is willing to tolerate large fluctuations in output (a large deviation of y from y

) to achieve a small reduction in the deviation of inflation from its target (π from π

). It prioritizes price stability above all else.

2.

Low β (“Inflation Dove”):

If a central bank places a lower weight on inflation stability (β is small), it is known as a “dove.” Its loss function indifference curves will be relatively

steep

. This means the bank is willing to tolerate significant deviations from its inflation target in order to keep output close to its target level. It prioritizes output and employment stabilization, even at the cost of higher inflation volatility.

Thus, the perception of the central bank—whether it is more concerned about inflation or output—is directly reflected in the value of β, which in turn determines the shape of the loss function and the trade-offs made in policy decisions.

Q11. Give a brief account of business cycle indicators.

Ans. Business cycle indicators are economic time-series data used to analyze and predict the direction of the overall economy. These indicators help economists and policymakers identify the current phase of the business cycle (expansion, peak, contraction, trough) and forecast future economic activity. The indicators are typically classified into three categories based on their timing relative to the overall economy:

1. Leading Indicators: These indicators tend to change direction before the overall economy changes. They are useful for forecasting future peaks and troughs. Examples include:
   • Stock prices (e.g., S&P 500)
   • Building permits for new private housing units
   • Average weekly hours, manufacturing
   • Index of consumer expectations
2. Coincident Indicators: These indicators move approximately in sync with the overall economy. They are useful for identifying the current state of the economy. Examples include:
   • Industrial production
   • Non-agricultural employment
   • Personal income less transfer payments
   • Manufacturing and trade sales
3. Lagging Indicators: These indicators change direction after the overall economy has changed. They are useful for confirming the timing of past business cycles. Examples include:
   • Average duration of unemployment
   • Consumer Price Index (CPI) for services
   • Ratio of inventories to sales
   • Commercial and industrial loans outstanding

To smooth out volatility and provide a clearer signal, individual indicators are often combined into

Composite Indexes

, such as the Conference Board’s Leading Economic Index (LEI).

Q12. Write short notes on any two of the following in about 100 words each: (a) Phases of business cycle (b) Adaptive expectations (c) Ricardian equivalence

Ans. (a) Phases of business cycle The business cycle refers to the fluctuations in aggregate economic activity. It has four main phases or stages:

1. Expansion: A period of growing economic activity, characterized by rising GDP, increasing employment, and growing incomes.
2. Peak: The highest point of the expansion, where economic growth slows and output is at its maximum level for that cycle.
3. Contraction: A period of declining economic activity, also known as a recession. GDP and employment fall.
4. Trough: The lowest point of the contraction, after which a new expansion cycle begins.

These phases do not occur at regular intervals, and they vary in length and intensity.

(b) Adaptive expectations Adaptive expectations is a theory suggesting that people form their expectations about the future based on past and present values. It is a backward-looking process. According to this theory, individuals adjust their expectations gradually based on their past forecast errors. For example, if inflation in the previous period was higher than expected, people would revise their inflation expectations for the next period slightly upwards. The implication is that expectations lag behind reality, leading to systematic forecast errors. This allows for a short-run trade-off between inflation and unemployment.

(c) Ricardian equivalence Ricardian equivalence (also known as the Barro-Ricardian equivalence proposition) states that financing government spending through debt is equivalent to financing it through taxes. The theory is that when a government cuts taxes and issues debt to cover the deficit, rational taxpayers understand that this debt must be repaid with higher taxes in the future. Therefore, they will save the entire amount of the tax cut to pay for their increased future tax liability. As a result, there is no effect on consumption, aggregate demand, or interest rates. The proposition relies on strong assumptions, such as perfect capital markets and infinitely-lived households.
