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.     

Mood Swings and Business Cycles: Evidence from Sign Restrictions

This paper provides new evidence that bouts of optimism and pessimism are an important source of U.S. business cycles, using the identification schemes based on sign restrictions. We document that identified optimism and pessimism shocks account for about 30% of U.S. business‐cycle fluctuations in hours and output. In addition, our empirical findings are consistent with the intensive‐ and extensive‐margin adjustments in the U.S. labor market over business cycles, providing further support to optimism shocks being an important source of U.S. business cycles. The identified optimism shocks are at least partially rational as total factor productivity is found to rise 8–12 quarters after an initial bout of optimism. While this later finding is consistent with some previous findings in the news shock literature, we cannot rule out that such episodes reflect self‐fulfilling beliefs.     

Moderate Inflation and the Deflation–Depression Link

Recent research has concluded that the historical evidence only provides weak support for the contention that deflation episodes are harmful to economic growth. In this paper, we revisit this relationship by allowing for inflation and growth to have a nonlinear specification dependent on inflation levels. In particular, we allow for the possibility that high inflation is negatively correlated with growth, while a positive relationship exists over the range of negative to moderate inflation. Our results confirm a positive relationship between inflation and growth at moderate inflation levels, and support the contention that the relationship between inflation and growth is nonlinear over the entire sample range.     

Mortgage Default during the U.S. Mortgage Crisis

Which theory can quantitatively explain the rise in mortgage defaults during the U.S. mortgage crisis? This paper finds that the double‐trigger hypothesis, which attributes mortgage default to the joint occurrence of negative equity and a life event such as unemployment, is consistent with the evidence. By contrast, a traditional frictionless default model strongly overpredicts the increase in default rates. This paper provides microfoundations for double‐trigger behavior in a model where unemployment causes liquidity problems for the borrower. This framework implies that mortgage crises may be mitigated at a lower cost by bailing out borrowers instead of lenders.     

Labor Force Participation and Monetary Policy in the Wake of the Great Recession

This paper provides compelling evidence that cyclical factors account for the bulk of the post‐2007 decline in the U.S. labor force participation rate (LFPR). We then formulate a stylized New Keynesian model in which the LFPR is practically acyclical during “normal times” but drops markedly following a large and persistent aggregate demand shock. These considerations have potentially crucial implications for the design of monetary policy, especially when interest rate adjustments are constrained by the zero lower bound; specifically, monetary policy can induce a more rapid recovery of the LFPR by allowing the unemployment rate to fall below its natural rate.     

Optimal Monetary Policy in a Model with Agency Costs

This paper integrates a fully explicit model of agency costs into an otherwise standard Dynamic New Keynesian model in a particularly transparent way. A principal result is the characterization of agency costs as endogenous markup shocks in an output‐gap version of the Phillips curve. The model's utility‐based welfare criterion is derived explicitly and includes a measure of credit market tightness that we interpret as a risk premium. The paper also fully characterizes optimal monetary policy and provides conditions under which zero inflation is the optimal policy. Finally, optimal policy can be expressed as an inflation targeting criterion that (depending upon parameter values) can be either forward or backward looking.     

Nonlinear Drift And Stochastic Volatility: An Empirical Investigation Of Short-Term Interest Rate Models

In this article I provide new evidence on the role of nonlinear drift and stochastic volatility in interest rate modeling. I compare various model specifications for the short‐term interest rate using the data from five countries. I find that modeling the stochastic volatility in the short rate is far more important than specifying the shape of the drift function. The empirical support for nonlinear drift is weak with or without the stochastic volatility factor. Although a linear drift stochastic volatility model fits the international data well, I find that the level effect differs across countries.     

Temptation and Self‐Control: Some Evidence and Applications

This paper studies the empirical relevance of temptation and self‐control using household‐level data from the Consumer Expenditure Survey. We construct an infinite‐horizon consumption‐savings model that allows, but does not require, temptation and self‐control in preferences. In the presence of temptation, a wealth–consumption ratio, in addition to consumption growth, becomes a determinant of the asset‐pricing kernel, and the importance of this additional pricing factor depends on the strength of temptation. To identify the presence of temptation, we exploit an implication of the theory that a more tempted individual should be more likely to hold commitment assets such as individual retirement account (IRA) or 401(k) accounts. Our estimation provides empirical support for temptation preferences. Based on our estimates, we explore some quantitative implications of this class of preferences for capital accumulation in a neoclassical growth model and the welfare cost of the business cycle.     

Mortgage Choice in the Euro Area: Macroeconomic Determinants and the Effect of Monetary Policy on Debt Burdens

This paper provides novel evidence on the role of the macroeconomic environment for households’ choice between fixed‐interest‐rate and adjustable‐interest‐rate mortgages (ARMs) in the euro area. We find that relatively more ARMs are taken out when economic growth is strong, the interest rate spread is high, or unemployment shows low volatility. A simulation exercise shows that a reduction in mortgage rates as witnessed during the monetary easing in the course of the global financial crisis produces a substantial decline in debt burdens among mortgage‐holding households, especially in countries where households have higher debt burdens and a larger share of ARMs.     

Information and volatility links in the foreign exchange market

We apply the trading model of Fleming et al (1998 ). to a number of currency markets. The model posits that two markets can have common volatility structures as a result of receiving common information and from cross‐hedging activity where a position in one currency is used to hedge risk in a position taken in another. Our results imply that the model is effective in identifying common information flows and volatility spillovers in the currency markets and that some of these effects are lost when simply examining raw correlations. A series of specification tests of the 21 bivariate systems that are examined provides support for the trading model in the foreign exchange context.     

Modelling Time‐Variation in the Stock Return‐Dividend Yield Predictive Equation

Using data for forty markets, this paper examines the nature and possible causes of time‐variation within the stock return‐dividend yield predictive regression. The results in this paper show that there is significant time‐variation in the predictive equation for returns and that such variation is linked to economic and market factors. Furthermore, the strength and nature of those links are themselves time‐varying. The inclusion of this time‐variation in the predictive equation increases the predictive power compared to the standard constant parameter predictive model. Evidence is also reported for time‐varying dividend growth predictability. Long‐horizon predictability is also examined with evidence reported that the nature of the factors affecting time‐varying predictability changes with horizon. The results here, while directly contributing to the returns predictability debate, in particular regarding its existence and source, may also inform the discussion that links time‐varying expected returns (and risk premium) to economic factors.     

Monetary policy when potential output is uncertain: Understanding the growth gamble of the 1990s

The Fed kept interest rates low and essentially unchanged during the late 1990s despite a booming economy and record-low unemployment. These interest rates were accommodative by historical standards. Nonetheless, inflation remained low. How did the Fed succeed in sustaining rapid economic growth without fueling inflation and inflationary expectations? In retrospect, it is evident that the productive capacity of the economy increased. Yet as events unfolded, there was uncertainty about the expansion of the capacity of the economy and therefore about the sustainability of the Fed's policy.This paper provides an explanation for the success of the Fed in accommodating growth with stable inflation in the late 1990s. It shows that if the central bank is committed to reverse policy errors it makes because of unwarranted optimism, inflation can remain in check even if the central bank keeps interest rates low because of this optimism. In particular, a price level target—which is a simple way to model a commitment to offset errors—can serve to anchor inflation even if the public does not share the central bank's optimism about shifts in potential output. The paper shows that price level targeting is superior to inflation targeting in a wide range of situations. The paper also provides econometric evidence that, in contrast to earlier periods, the Fed has recently put substantial weight on the price level in setting interest rates. Moreover, it shows that CPI announcement surprises lead to reversion in the price level. Finally, it provides textual evidence that Alan Greenspan puts relatively more weight on the price level than inflation.     

US Fiscal Sustainability and the Causality Relationship between Government Expenditures and Revenues: A New Approach Based on Quantile Cointegration

This paper first aims to reinvestigate the issue of US fiscal sustainability by using the quantile cointegration approach proposed by Xiao (2009 and 2012). Our empirical evidence indicates a quantile‐dependent cointegrating relationship between government expenditures and revenues. In addition, this paper examines the long‐run causality relationship between expenditures and revenues by using the vector error‐correction (VEC) model with coefficients based on the different quantiles. Findings from the long‐run Granger‐causality analyses support the spend‐and‐tax hypothesis. Our investigation suggests that the government should show more discretion in increasing expenditures in the long run. Moreover, budget deficit reduction can only be achieved through reductions in government expenditures.     

On‐the‐Job Learning and News‐Driven Business Cycles

This paper proposes a new channel of on‐the‐job learning to explain the positive comovement between consumption and employment following good news about future productivity. The new recruits can generate an additional stream of output production in all future periods, and the firm's labor demand is thus characterized by the forward‐looking property. Therefore, the firm is motivated to hire more new recruits in advance in response to good news about future productivity. Once the increase in labor demand is greater than the decrease in labor supply caused by the income effect, the coincident rise in consumption and employment can be driven by the news shock. When such a channel is paired with investment adjustment costs and the endogenous capacity utilization rate, this paper provides a plausible explanation for simultaneous booms in current consumption, investment, output, and employment to match the empirical evidence under the news shock.     

The Federal Home Loan Bank System: The Lender of Next‐to‐Last Resort?

The Federal Home Loan Bank (FHLB) System is a large cooperatively owned government‐sponsored liquidity facility that lends predominately to U.S. depository institutions. This paper documents the significant role played by the FHLB System at the outset of the recent financial crisis and provides evidence on the uses of FHLB funding by member banks and thrifts during that time. We then compare lending activity by the FHLB System and the Federal Reserve during 2007 and 2008, discuss the types of institutions seeking government‐sponsored liquidity at various times, and identify the trade‐offs faced by borrowers eligible to tap liquidity from both facilities.     

Aggregate Implications of Heterogeneous Households in a Sticky‐Price Model

This paper analyzes the role of heterogeneous households in propagating shocks over the business cycle by generalizing a basic sticky‐price model to allow for imperfect risk sharing between households that differ in labor incomes. I show that imperfectly insured household consumption distorts household incentive to supply labor hours through an idiosyncratic income effect, which in turn generates strategic complementarities in price setting and thus amplifies business cycle fluctuations. This mechanism diminishes the role of nominal rigidities and makes sticky‐price models more consistent with microeconomic evidence on the frequency of price changes.     

Deposit rate ceilings and monetary transmission in the US

Establishing the existence and nature of changes in the conduct and transmission of monetary policy is key in understanding the remarkable macroeconomic performance of the US since the mid-1980s. This paper presents evidence on a phenomenon of disintermediation occurring during the major recessions in the 1960s and 1970s, but absent ever since, and shows that disintermediation is closely linked to the existence of deposit rate ceilings under regulation Q. In a monetary DSGE model that incorporates deposit rate ceilings as occasionally binding constraints, the regulation alters the behavior of money aggregates and exacerbates the drop in economic activity following a monetary tightening. The results of a threshold VAR lend support to the main theoretical predictions of the model.     

Aggregate Stability and Balanced‐Budget Rules

It has been shown that under perfect competition and a Cobb‐Douglas production function, a basic real business cycle model may exhibit indeterminacy and sunspot fluctuations when income tax rates are determined by a balanced‐budget rule (BBR). This paper introduces in an otherwise standard real business cycle model a more general and data‐coherent class of production functions, namely, a constant elasticity of substitution production function. We show that the degree of substitutability between production factors is a key ingredient to understanding the (de)stabilizing properties of a BBR. Then we calibrate the model consistently with the empirical evidence; that is, we set the elasticity of substitution between labor and capital below unity. We show that compared to the Cobb‐Douglas case, the likelihood of indeterminacy under a BBR is greatly reduced in the U.S., the EU, and the UK.     

Price‐matching guarantees

Are price‐matching guarantees anticompetitive? We examine the incentives for price‐matching guarantees in markets where information about prices is costly. The conventional explanation of price matching as facilitating cartel pricing finds some theoretical support, but our model provides an additional explanation. A price‐matching guarantee may be a credible and easily understood means of communicating to uninformed consumers that a firm is low priced. The credibility of the signal is assured by the behavior of informed consumers. We contrast the testable implications of our model with those arising from two theories of price matching as anticompetitive, and show that available evidence supports the signalling theory.     

Real Wage Rigidities and the New Keynesian Model

Most central banks perceive a trade‐off between stabilizing inflation and stabilizing the gap between output and desired output. However, the standard new Keynesian framework implies no such trade‐off. In that framework, stabilizing inflation is equivalent to stabilizing the welfare‐relevant output gap. In this paper, we argue that this property of the new Keynesian framework, which we call the divine coincidence, is due to a special feature of the model: the absence of nontrivial real imperfections. We focus on one such real imperfection, namely, real wage rigidities. When the baseline new Keynesian model is extended to allow for real wage rigidities, the divine coincidence disappears, and central banks indeed face a trade‐off between stabilizing inflation and stabilizing the welfare‐relevant output gap. We show that not only does the extended model have more realistic normative implications, but it also has appealing positive properties. In particular, it provides a natural interpretation for the dynamic inflation–unemployment relation found in the data.
