Monetary and Fiscal Policy Switching

A growing body of evidence finds that policy reaction functions vary substantially over different periods in the United States. This paper explores how moving to an environment in which monetary and fiscal regimes evolve according to a Markov process can change the impacts of policy shocks. In one regime monetary policy follows the Taylor principle and taxes rise strongly with debt; in another regime the Taylor principle fails to hold and taxes are exogenous. An example shows that a unique bounded non-Ricardian equilibrium exists in this environment. A computational model illustrates that because agents' decision rules embed the probability that policies will change in the future, monetary and tax shocks always produce wealth effects. When it is possible that fiscal policy will be unresponsive to debt at times, active monetary policy (like a Taylor rule) in one regime is not sufficient to insulate the economy against tax shocks in that regime and it can have the unintended consequence of amplifying and propagating the aggregate demand effects of tax shocks. The paper also considers the implications of policy switching for two empirical issues.     

Financial Differences and Business Cycle Co-Movements in a Currency Area

I propose a unitary framework to interpret the links between differences in financial structures and the monetary policy regimes, on the one hand, and the correlation of business cycles, on the other. Using a two-country micro-founded model with financial frictions I predict that a greater financial diversity should reduce cyclical correlation under a given monetary regime and that moving from independent monetary policies to a hard peg or a common currency should increase it, for any given degree of financial diversity. I use the recent experience of EMU to test these ideas and show that my model explains reasonably well the broad patterns of business cycle correlation observed recently among the main euro area countries.     

Effects of Monetary and Macroprudential Policies—Evidence from Four Inflation Targeting Economies

We examine the effects of monetary and macroprudential policies in the Asia‐Pacific region, where many inflation targeting economies have adopted macroprudential policies in order to safeguard financial stability. Using structural panel vector autoregressions that identify both monetary and macroprudential policy actions, we show that tighter macroprudential policies used to contain credit growth also have a significant negative impact on macroeconomic aggregates such as real GDP and the price level. The similar effects of monetary and macroprudential policies may suggest a complementary use of the two policies at normal times. However, they could also create challenges for policymakers, especially during times when low inflation coincides with buoyant credit growth.     

Keynesian Inefficiency and Optimal Policy: A New Monetarist Approach

A simple model of monetary/labor search is constructed to study Keynesian indeterminacy and optimal policy. In the model, economic agents have trouble splitting the surplus from exchange appropriately, and we consider monetary and fiscal policies that correct this Keynesian inefficiency. A Taylor rule neither implies determinacy, nor does it support an efficient outcome. An optimal policy yields an efficient and determinate allocation of resources, but equilibrium policy actions, wages, and prices are indeterminate at the optimum.     

Quantifying tax effects under policy foresight

Studies of tax effects make the conventional information assumption that changes in period-t taxes become known at t. Legislative lags, however, imply that news arrives before tax changes take place. Under policy foreknowledge, the conventional information structure is therefore misspecified. Simulations of a standard neoclassical growth model suggest that foresight of only one quarter can distort substantially the estimates of tax effects obtained under the no-foresight assumption. Also, it is crucial to model capital and labor taxes separately: anticipated changes in these two tax policies have opposite effects on consumption, investment, labor, and output before policy realization.     

Estimating monetary policy effects when interest rates are close to zero

Using a nonlinear structural VAR approach, we estimate the effects of exogenous monetary policy shocks in the presence of a zero lower bound constraint on nominal interest rates and examine the impact of such a constraint on the effectiveness of counter-cyclical monetary policies based on the data from Japan. We find that when interest rates are at zero, the output effect of exogenous shocks to monetary policy is cut in half if the central bank continues to target the interest rate. The conditional impulse response functions allow us to isolate the effect of monetary policy shocks operating through the interest rate channel when other possible channels of monetary transmission are present.     

Supply‐Side Policies in the Depression: Evidence from France

The effects of supply‐side policies in depressed economies are controversial. We shed light on this debate using evidence from France in the 1930s. In 1936, France departed from the gold standard and implemented mandatory wage increases and hours restrictions. Deflation ended but output stagnated. We present time‐series and cross‐sectional evidence that these supply‐side policies, in particular the 40‐hour law, contributed to French stagflation. These results are inconsistent both with the standard one‐sector New Keynesian model and with a medium scale, multisector model calibrated to match our cross‐sectional estimates. We conclude that the New Keynesian model is a poor guide to the effects of supply‐side shocks in depressed economies.     

Bubbles and capital flow volatility: Causes and risk management

Emerging market economies are fertile ground for the development of real estate and other financial bubbles. Despite these economies’ significant growth potential, their corporate and government sectors do not generate the financial instruments to provide residents with adequate stores of value. Capital often flows out of these economies seeking these stores of value in the developed world. Bubbles are beneficial because they provide domestic stores of value and thereby reduce capital outflows while increasing investment. But they come at a cost, as they expose the country to bubble-crashes and capital flow reversals. We show that domestic financial underdevelopment not only facilitates the emergence of bubbles, but also leads agents to undervalue the aggregate risk embodied in financial bubbles. In this context, even rational bubbles can be welfare reducing. We study a set of aggregate risk management policies to alleviate the bubble-risk. We show that liquidity requirements, sterilization of capital inflows and structural policies aimed at developing public debt markets ‘collateralized’ by future revenues, all have a high payoff in this environment.     

Political budget cycles in new versus established democracies

Like other recent studies, we find a political deficit cycle in a large cross-section of countries, but show that this result is driven by the experience of “new democracies”. The political budget cycle in new democracies accounts for the finding of a budget cycle in larger samples that include these countries and disappears when they are removed from the larger sample. The political deficit cycle in new democracies accounts for findings in both developed and less developed economies, for the stronger cycle in weaker democracies, and for differences in the political cycle across governmental and electoral systems. Our findings may reconcile two contradictory views of pre-electoral manipulation, one that it is a useful instrument to gain voter support and a widespread empirical phenomenon, the other that voters punish rather than reward fiscal manipulation.     

Robust monetary policy with imperfect knowledge

We examine the performance and robustness properties of monetary policy rules in an estimated macroeconomic model in which the economy undergoes structural change and where private agents and the central bank possess imperfect knowledge about the true structure of the economy. Policymakers follow an interest rate rule aiming to maintain price stability and to minimize fluctuations of unemployment around its natural rate but are uncertain about the economy's natural rates of interest and unemployment and how private agents form expectations. In particular, we consider two models of expectations formation: rational expectations (RE) and learning. We show that in this environment the ability to stabilize the real side of the economy is significantly reduced relative to an economy under RE with perfect knowledge. Furthermore, policies that would be optimal under perfect knowledge can perform very poorly if knowledge is imperfect. Efficient policies that take account of private learning and misperceptions of natural rates call for greater policy inertia, a more aggressive response to inflation, and a smaller response to the perceived unemployment gap than would be optimal if everyone had perfect knowledge of the economy. We show that such policies are quite robust to potential misspecification of private sector learning and the magnitude of variation in natural rates.     

The Effectiveness of Unconventional Monetary Policy at the Zero Lower Bound: A Cross‐Country Analysis

This paper assesses the macroeconomic effects of unconventional monetary policies by estimating a panel vector autoregression (VAR) with monthly data from eight advanced economies over a sample spanning the period since the onset of the global financial crisis. It finds that an exogenous increase in central bank balance sheets at the zero lower bound leads to a temporary rise in economic activity and consumer prices. The estimated output effects turn out to be qualitatively similar to the ones found in the literature on the effects of conventional monetary policy, while the impact on the price level is weaker and less persistent. Individual country results suggest that there are no major differences in the macroeconomic effects of unconventional monetary policies across countries, despite the heterogeneity of the measures that were taken.     

International and historical dimensions of the financial crisis of 2007 and 2008

This article provides an interpretative overview of the papers in this special issue of JIMF devoted to international aspects of the 2007–2009 financial crisis. It then goes on to provide additional empirical evidence of two sorts. The first documents the difference between the monetary policies pursued by the European Central Bank, the Bank of Japan, the Bank of England and the Federal Reserve in this episode and the policies pursued by the Federal Reserve in the Great Depression. In the course of this episode, unlike the Great Depression, policies were not contractionary and the recessions were less severe than in the United States in 1929–1933. The second compares the recovery in the United States in the aftermath of the recent crisis and in recoveries following periods of previous banking crises. This recovery is much weaker than average.     

The Credit Channel at the Zero Lower Bound through the Lens of Equity Prices

This study examines the impact of unconventional monetary policies on the stock market when the short‐term nominal interest rate is stuck at the zero lower bound (ZLB). Unconventional monetary policies appear to have significant effects on stock prices and the effects differ across stocks. In agreement with existing credit channel theories, I find that firms subject to financial constraints react more strongly to unconventional monetary policy shocks [especially large‐scale asset purchases (LSAPs)] than do less constrained firms. These results imply that the credit channel is as important as the interest rate channel in the transmission of unconventional monetary policies at the ZLB.     

Approximate valuation of joint life policies

Abstract

1. As a rule the number of joint life policies is very small compared with that of single life policies. Unless the acquisition policy of a company especially aims at effecting the former kind of policies, hardly more than one or two per mille of the total amount of the policies issued will cover more than one life. Under such circumstances it will not pay to combine these few policies in a special valuation group.     

The impact of macroeconomic uncertainty on non-financial firms' demand for liquidity

This paper empirically investigates whether changes in macroeconomic volatility affect the efficient allocation of non-financial firms' liquid assets. We argue that higher uncertainty will hamper managers' ability to accurately predict firm-specific information and induce them to implement similar cash management policies. Contrarily, when the macroeconomic environment becomes more tranquil, each manager will have the latitude to behave more idiosyncratically as she can adjust liquid assets based on the specific requirements of the firm, bringing about a more efficient allocation of liquid assets. Our empirical analysis provides support for these predictions.     

Reconciling Bagehot and the Fed's Response to September 11

Bagehot (1873) states that to prevent bank panics a central bank should provide liquidity at a "very high rate of interest." In contrast, most of the theoretical literature on liquidity provision suggests that central banks should lend at an interest rate of zero. This is broadly consistent with the Federal Reserve's behavior in the days following September 11, 2001. This paper shows that both policies can be reconciled. With commodity money, as in Bagehot's time, liquidity is scarce and a high price allows banks to self-select. In contrast, the Fed has a virtually unlimited ability to temporarily expand the money supply so self-selection is unnecessary.     

The future of social security

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the standard OLG model with capital accumulation, we find that intergenerational transfers arise in the absence of altruism, commitment, or trigger strategies. Closed-form solutions predict population ageing to lead to higher social security tax rates, a rising share of pensions in GDP, but eventually lower social security benefits per retiree. The response of equilibrium tax rates to demographic shocks reduces old-age consumption risk. Calibrated to match features of the U.S. economy, the model suggests that, in response to the projected demographic transition, social security tax rates will gradually increase to 16%. Other policies that distort labor supply will become less important; labor supply therefore will rise, in contrast with frequently voiced fears.     

Monetary Policy in a Low‐Inflation Environment: Developing a State‐Contingent Price‐Level Target

A number of academic studies find that either price‐level targeting or temporary above‐average inflation are nearly optimal policies to address a liquidity trap crisis. Still, central bankers and the public generally question whether even a temporarily higher inflation rate could be beneficial in addressing a liquidity trap or could be consistent with price stability over the longer term. At the same time, however, the Federal Reserve's projections for high unemployment and low inflation do not seem to be consistent with the best monetary policies to address the Fed's dual mandate responsibilities. Accordingly, it is useful to seriously discuss these potentially beneficial alternative policies.     

Distortionary Taxation, Debt, and the Price Level

This paper compares the determinacy of equilibria under exogenous interest rates in an economy with a cash constraint, in which taxation is lump-sum or distortionary. Under passive fiscal policies lump-sum taxes generate nominal indeterminacy, while with distortionary taxes indeterminacy can be real, but not purely nominal. In general, under distortionary taxation uniqueness of the equilibrium allocation depends on monetary and fiscal policy interactions through taxes, debt, and interest rates. To illustrate this principle, we consider balanced-budget policies under distortionary income taxation and show that a unique equilibrium allocation prevails if interest rates are set consistent with long-run deflation. A separate section extends the analysis to endogenous interest rates.
