Bank profitability during recessions

This paper contributes to the literature on the relation between bank profitability and economic activity. When allowing for stronger co-movement of bank profit with economic activity during deep recessions, we find a much larger impact of output growth on bank profitability than commonly found in the literature. Among the different components of bank profit, loan losses are the main driver of this result. We also find long-term interest rates in previous years to be important determinants of bank profit in times of high economic growth. Our findings are robust to the use of aggregate or individual bank data.     

Firm dynamics, markup variations, and the business cycle

We present a model in which net business formation is endogenously procyclical. Variations in the number of operating firms lead to countercyclical variations in markups that give rise to endogenous procyclical movements in measured total factor productivity (TFP). Based on this result, the paper suggests a simple structural decomposition of variations in TFP into those originating from exogenous shocks and those originating endogenously from the interaction between firms’ entry and exit decisions and the degree of competition. The decomposition suggests that around 40% of the movements in measured TFP can be attributed to this interaction. Moreover, the paper analyzes the effects on (i) the measurement of the volatility of exogenous shocks in the U.S. economy and (ii) the magnification of shocks over the business cycle.     

Costs of business cycles for unskilled workers

Unskilled workers are subject to a much larger risk of unemployment during recessions than are skilled workers. Moreover, unskilled workers earn less income, which limits their ability to self-insure. We examine how this heterogeneity in unemployment risk and income across different skill groups translates into heterogeneity in the cost of business cycles. We find that the welfare cost of business cycles for unskilled workers is substantially higher than the welfare cost for skilled workers.     

The Response of Hours to a Technology Shock: A Two-Step Structural VAR Approach

The response of hours to a technology shock is a controversial issue in macroeconomics. Part of the difficulty lies in that the estimated response is sensitive to the specification of hours in structural vector autoregressions (SVARs). This paper uses a simple two-step approach to consistently estimate the response of hours. The first step considers a SVAR model with a relevant stationary variable, but excluding hours. Given a consistent estimate of technology shocks in the first step, the response of hours to this shock is estimated in a second step. Simulation experiments from an estimated dynamic stochastic general equilibrium (DSGE) model show that this approach outperforms standard SVARs. When applied to U.S. data, the two-step approach predicts a short-run decrease followed by a hump-shaped positive response. This result is robust to other specifications and data.     

The Dynamic Relationship between Permanent and Transitory Components of U.S. Business Cycles

This paper investigates the dynamic relationship between permanent and transitory components of post-war U.S. business cycles. We specify a time-series model for real GNP and consumption in which the two share a common stochastic trend and transitory component, and Markov-regime switching is used to model business cycle phases in these components. The timing of switches between business cycle phases is allowed to differ across the permanent and transitory components. We find strong evidence of a lead-lag relationship between the switches in the two components. Specifically, switches in the permanent component leads switches in the transitory component when entering recessions.     

Estimating Central Bank Preferences under Commitment and Discretion

This paper explains U.S. macroeconomic outcomes with an empirical New Keynesian model in which monetary policy minimizes the central bank’s loss function. The presence of expectations in the model forms a well‐known distinction between two modes of optimization, termed commitment and discretion. The model is estimated separately under each policy using maximum likelihood over the Volcker–Greenspan–Bernanke period. Comparisons of fit reveal that the data favor the specification with discretionary policy. Estimates of the loss function weights point to an excessive concern for interest rate smoothing in the commitment model but a more balanced concern relative to inflation and output stability in the discretionary model.     

Fiscal policy and financial market movements

This paper estimates fiscal policy reaction function in order to investigate the links between financial market movements and fiscal policy outcomes. An increase in asset prices affects in a positive and significant manner primary balances, with the response reflecting both an increase in government revenues and a fall in government spending. The most important impact on fiscal balances is due to changes in residential property prices. Changes in equity and commercial property prices are also important determinants of fiscal balances. Our findings suggest that the steepening of the slope of the yield curve contributes to expenditure based fiscal discipline.     

What Makes the Output–Inflation Trade‐Off Change? The Absence of Accelerating Deflation in Japan

It is standard to model the output–inflation trade-off as a linear relationship with a time-invariant slope. We assess empirical evidence for two sets of theories that allow for endogenous variation in the slope of the short-run Phillips curve. At an empirical level, we examine why large negative output gaps in Japan in the late 1990s did not lead to accelerating deflation but instead coincided with stable, albeit moderately negative inflation. Our results suggest that this episode is most convincingly interpreted as reflecting a gradual flattening of the Phillips curve. We find that this flattening is best explained by models with endogenous price durations. These models imply that in any economy where trend inflation is substantially lower (or substantially higher) today than in past decades, time variation in the slope of the Phillips curve has become too important to ignore.     

A general theory of controllability and expectations anchoring for small-open economies

Rational expectations are often used as an argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances rational expectations can enhance our power to control an economy over time. In those cases, policy announcements can be used to extend the impact of conventional policy instruments. We present a general forward-looking policy framework and use it to provide a formal rationale for testing when policymakers can and cannot expect to be able to manage expectations. To describe the relevance of our results applications are shown for policy design in small-open economies. Those are the cases where domestic policies are at their weakest and our ability to influence expectations most constrained.     

Cross-sectional heterogeneity and the persistence of aggregate fluctuations

The microevidence indicates that small firms grow faster than big firms. I argue that this relationship between the expected growth rate of a firm and its size may provide a microfoundation for the well-known high degree of persistence of shocks to aggregate output. The logic goes as follows. Almost any shock tends to temporarily alter firms' incentive to invest in growth thereby leading to a reallocation of firms across size categories. If small firms grow faster than big ones, the impact effect of the shock on aggregate output is gradually absorbed. But, as fast growing small firms become big and start to grow at the lower rate of big firms, the rate at which the shock is absorbed decreases over the adjustment path. As a result, shocks are absorbed, yet at a very low decreasing rate which induces long memory in aggregate output. I argue that this transmission mechanism may reconcile the microevidence with the observed degree of aggregate persistence. It requires changes in neither the number of firms in the market nor the rate of technological progress. It is merely the result of the cross-sectional heterogeneity that we observe in real economies.     

Price and Investment Dynamics: Theory and Plant-Level Data

We construct a model of a firm competing for market share in a customer market and making investments in physical capital. The firm is financially constrained and there are implementation lags in investment. Our model predicts that product prices should depend on costs and competitors' prices but respond weakly to demand shocks. Also, prices should be strongly related to investment. We estimate price and investment equations on panel data for Swedish manufacturing plants and find results that are qualitatively in line with these predictions, though the relation between investment and prices is stronger than predicted by our model.     

The Relationships between Permanent and Transitory Movements in U.S. Output and the Unemployment Rate

This paper estimates the permanent and transitory movements in U.S. output and the unemployment rate and the relationships between them. The results suggest that permanent movements in U.S. output and the unemployment rate are important for explaining overall fluctuations. Further, the correlation between changes in these series arises in large part due to the relationship between their permanent components.     

The Slow Adjustment of Aggregate Consumption to Permanent Income

This paper investigates the relationship between aggregate consumption and permanent income using a new approach to the estimation of cointegrated systems that builds on Stock and Watson's common stochastic trends representation. The permanent and transitory movements in aggregate income and consumption are estimated directly using the Kalman filter and are allowed to be correlated. This approach avoids any implicit restriction that permanent income be as smooth as consumption. Instead, permanent income appears to be relatively volatile, with consumption adjusting toward it only slowly over time. These results provide a clear rejection of the standard version of the permanent income hypothesis and are suggestive of alternative theories of consumption behavior such as habit formation or precautionary savings.     

Estimation of the equilibrium exchange rate: The CHEER approach

The paper presents the results of an investigation where the concept of a steady-state level of the exchange rate is equated with the capital market equilibrium based on the CHEER approach. The empirical analysis concentrates on Poland, because in this case the assessment of the equilibrium exchange rate is of vital importance. The prospect of the Polish currency joining the ERM2 provokes controversies and requires research into the economic consequences of accession to the EMU. The international transmission mechanisms affecting the Polish economy are identified within the VEqCM framework. The calculations indicate that in the last years of the analyzed sample (i.e. up to December 2006) the zloty/euro exchange rate was slightly overvalued, and the steady-state level was found to have been adjusting to the value of 4.1 zlotys.     

The Spirit of Capitalism, Precautionary Savings, and Consumption

Recent research has shown that the "spirit of capitalism"—a preference for wealth itself, in addition to consumption—has important implications for growth and asset pricing. This paper explores how the spirit of capitalism affects saving and consumption behavior. We demonstrate that the spirit of capitalism may reduce the importance of precautionary savings. It can also explain the excess sensitivity puzzle: the spirit of capitalism causes dramatic deviations from a random walk. It may also offer a partial explanation of the excess smoothness puzzle.     

The extensive margin and monetary policy

The creation of new firms, referred to as the extensive margin, is a significant but overlooked dimension of monetary policy. A monetary VAR documents that monetary policy has significant effects on firm creation. An analytically tractable model combining sticky prices and firm entry shows that entry alters the transmission of monetary policy innovations, acting much like a type of investment in more standard models. Monetary policy rules that offset the uncertainty of productivity shocks can raise the mean level of entry and thereby welfare, suggesting a new motivation for stabilization policy.     

The “price puzzle” reconsidered

A large literature has employed structural vector autoregressive (SVAR) models to investigate the empirical effects of U.S. monetary policy. Many of these models regularly produce a “price puzzle”—a rise in the aggregate price level in response to a contractionary innovation to monetary policy—unless commodity prices are included. Conventional wisdom maintains that commodity prices resolve the price puzzle because they contain information that helps the Federal Reserve forecast inflation. I examine a number of plausible alternative indicator variables and find little correlation between an ability to forecast inflation and an ability to resolve the price puzzle. Additionally, a sub-sample investigation reveals that evidence of a price puzzle is associated primarily with the 1959-1979 sample period, and that most indicators—including commodity prices—cannot resolve the puzzle over this period.     

Demand and productivity components of business cycles: Estimates and implications

Standard stochastic growth models provide theoretical restrictions on output decomposition which can be used to investigate whether productivity shocks played a major role in observed business cycles. Applying these restrictions to US data leads to the following findings: (i) Business cycles implied by productivity shocks are mildly correlated to overall fluctuations and help account for a few episodes of US postwar recessions. However, only 20% of US fluctuations can be explained by these shocks. (ii) Most fluctuations seem instead to be due to “nominal demand” shocks, i.e. shocks which move output and prices in the same direction, but whose effects on output are ultimately transitory. (iii) Canonical sticky price models in the new-neoclassical synthesis tradition can account for the cyclical comovements of output and prices, but canonical, frictionless, RBC models cannot.     

Fundamental Economic Shocks and the Macroeconomy

We ask how macroeconomic and financial variables respond to empirical measures of shocks to technology, labor supply, and monetary policy. These three shocks account for the preponderance of output, productivity, and price fluctuations. Only technology shocks have a permanent impact on economic activity. Labor inputs have little initial response to technology shocks. Monetary policy has a small response to technology shocks but "leans against the wind" in response to the more cyclical labor supply shock. This shock has the biggest impact on interest rates. Stock prices respond to all three shocks. Other empirical implications of our approach are discussed.
