Equilibrium Unemployment, Job Flows, and Inflation Dynamics

In order to explain the joint fluctuations of output, inflation and the labor market, this paper develops and estimates a general equilibrium model that integrates a theory of equilibrium unemployment into a monetary model with nominal price rigidities. The estimated model accounts for the responses of employment, hours per worker, job creation, and job destruction to a monetary policy shock. Moreover, search frictions in the labor market generate a lower elasticity of marginal costs with respect to output. This helps to explain the sluggishness of inflation and the persistence of output that are observed in the data.     

Measuring the Information Content of the Beige Book: A Mixed Data Sampling Approach

Studies of the predictive ability of the Federal Reserve's Beige Book for aggregate output and employment have proven inconclusive. This might be attributed, in part, to its irregular release schedule. We use a model that allows for data sampling at mixed frequencies to analyze the predictive power of the Beige Book. We find that the Beige Book's national summary and District reports predict GDP and aggregate employment and that most District reports provide information content for regional employment. In addition, there appears to be an asymmetry in the predictive content of the Beige Book language.     

A Short History of Price Level Convergence in Europe

We study the evolution of price level dispersion in Europe by combining time-series information on harmonized indices of consumer prices (HICPs) with occasional observations of absolute price levels. We find that European price levels converged over much of the last 40 to 50 years. In the United States, our benchmark, price level dispersion is more or less stable. A back-of-the-envelope calculation suggests that indirect tax rate harmonization, convergence of nontraded input costs, and convergence of traded input costs (in the form of exchange rate stability and increased openness) are all important in explaining European price level convergence.     

On the reversal of return and dividend growth predictability: A tale of two periods

A disconcerting, albeit generally accepted, finding is that aggregate stock returns are predictable by dividend yield but dividend growth is unpredictable. I show that part of this lack of dividend growth predictability stems from how dividend growth is constructed. I then show a dramatic reversal of predictability in the 134 years during 1872–2005: stock returns are largely unpredictable in the first seven decades, but become predictable in the postwar period; dividend growth is strongly predictable in the prewar years but this predictability disappears in the postwar years. New evidence on the predictability of long-run returns and dividend growth is also shown.     

Why did the average duration of unemployment become so much longer?

There has been a substantial increase in the average duration of unemployment relative to the unemployment rate in the U.S. over the last 30 years. We evaluate the performance of a standard job-search model in explaining this phenomenon. In particular, we examine whether the increase in within-group wage inequality and the decline in the incidence of unemployment can account for the increase in unemployment duration. The results indicate that these two changes can explain a significant part of the increase over the last 30 years, although the model fails to match the behavior of unemployment duration during 1980s.     

Identifying the interdependence between US monetary policy and the stock market

We estimate the interdependence between US monetary policy and the S&P 500 using structural vector autoregressive (VAR) methodology. A solution is proposed to the simultaneity problem of identifying monetary and stock price shocks by using a combination of short-run and long-run restrictions that maintains the qualitative properties of a monetary policy shock found in the established literature [Christiano, L.J., Eichenbaum, M., Evans, C.L., 1999. Monetary policy shocks: what have we learned and to what end? In: Taylor, J.B., Woodford, M. (Eds.), Handbook of Macroeconomics, vol. 1A. Elsevier, New York, pp. 65-148]. We find great interdependence between the interest rate setting and real stock prices. Real stock prices immediately fall by seven to nine percent due to a monetary policy shock that raises the federal funds rate by 100 basis points. A stock price shock increasing real stock prices by one percent leads to an increase in the interest rate of close to 4 basis points.     

The irreversibility premium

When investment is irreversible, theory suggests that firms will be “reluctant to invest.” This reluctance creates a wedge between the discount rate guiding investment decisions and the standard Jorgensonian user cost (adjusted for risk). We use the intertemporal tradeoff between benefits and costs of changing the capital stock to estimate this wedge, which we label the irreversibility premium. Estimates are based on panel data for the period 1980-2001. The large dataset allows us to estimate the effects of limited resale markets, low depreciation rates, high uncertainty, and negative industry-wide shocks on the irreversibility premium. Our estimates provide a readily interpretable measure of the importance of irreversibility and document that the irreversibility premium is both economically and statistically significant.     

Exchange rate volatility and productivity growth: The role of financial development

The vast empirical exchange rate literature finds the effect of exchange rate volatility on real activity to be small or insignificant. In contrast, this paper offers empirical evidence that real exchange rate volatility can have a significant impact on productivity growth. However, the effect depends critically on a country's level of financial development. The results appear robust to time window, alternative measures of financial development and exchange rate volatility, and outliers. We also offer a simple monetary growth model in which real exchange rate uncertainty exacerbates the negative investment effects of domestic credit market constraints.     

How strong is the macroeconomic case for downward real wage rigidity?

We explore the existence of downward real wage rigidity (DRWR) at the industry level, based on data from 19 OECD countries for the period 1973-1999. The results show that DRWR compresses the distributions of industry wage changes overall, as well as for specific geographical regions and time periods, but there are not many real wage cuts that are prevented. More important, however, DRWR attenuates larger real wage cuts, thus leading to higher real wages. There is stronger evidence for downward nominal wage rigidity than for DRWR. Real wage cuts are less prevalent in countries with strict employment protection legislation and high union density.     

The bright and dark side of staging: Investment performance and the varying motivations of private equity firms

Previous papers that examined investment decisions by private equity funds are divided on whether staging has a positive or negative effect on returns. We believe these opposing views can be reconciled by studying when staging is used during the life of the investment relationship: We find that staging has a positive effect on investment returns in the beginning of the investment relationship, consistent with the notion that staging helps mitigate information asymmetry. However, staging appears to be negatively associated with returns when used prior to the exit decision. Our unique dataset allows us to measure these intertemporal effects precisely.
