Will a Surge in Labor Force Participation Impede Unemployment Rate Improvement?
The labor force participation rate has been falling since 2000, a trend that accelerated somewhat during the recession of 2007-09. Some economists and journalists have questioned whether recent improvements in the labor market will cause non-participants to re-enter the labor force at a faster rate, thus offsetting job growth and impeding further declines in the unemployment rate. But recent worker-flow research suggests that this scenario is unlikely.

On the implementation of Markov-perfect interest rate and money supply rules: global and local uniqueness
Currently there is a growing literature exploring the features of optimal monetary policy in New Keynesian models under both commitment and discretion. This literature usually solves for the optimal allocations that are consistent with a rational expectations market equilibrium, but it does not study how the policy can be implemented given the available policy instruments. Recently, however, King and Wolman (2004) have shown that a time-consistent policy cannot be implemented through the control of nominal money balances. In particular, they find that equilibria are not unique under a money ...

Inflation Targeting: Could Bad Luck Explain Persistent One-Sided Misses?
In January 2012, the Federal Open Market Committee set an explicit inflation target of 2 percent, but the annual inflation rate has been 0.25 percentage points or more below that target for the past 10 quarters. Extended periods of one-sided misses are common among inflation-targeting countries, but it is not clear whether these persistent deviations are caused by structural changes, bad policy or bad luck. Analysis of the statistical properties of the inflation process in the United States suggests that bad luck remains a plausible explanation for the FOMC's current string of one-sided ...

(S,s) Inventory policies in general equilibrium
We study the aggregate implications of (S,s) inventory policies in a dynamic general equilibrium model with aggregate uncertainty. Firms in the model's retail sector face idiosyncratic demand risk, and (S,s) inventory policies are optimal because of fixed order costs. The distribution of inventory holdings affects the aggregate outcome in two ways: variation in the decision to order and variation in the rate of sale through the pricing decisions of retailers. We find that both mechanisms must operate to reconcile observations that orders are more volatile than, and inventory investment is ...

The role of real wages, productivity and fiscal policy in Germany's Great Depression 1928-1937
We study the behavior of output, employment, consumption, and investment in Germany during the Great Depression of 1928-37. In this time period, real wages were countercyclical, and productivity and fiscal policy were procyclical. We use the neoclassical growth model to investigate how much these factors contribute to the Depression. We find that real wages, which were significantly above their market clearing levels, were the most important factor for the economic decline in the Depression. Changes in productivity and fiscal policy were also important for the decline and recovery. Even ...

Vintage capital as an origin of inequalities
Does capital-embodied technological change play an important role in shaping labor market inequalities? This paper addresses the question in a model with vintage capital and search / matching frictions where costly capital investment leads to large heterogeneity in productivity among vacancies in equilibrium. The paper first demonstrates analytically how both technology growth and institutional variables affect equilibrium wage inequality, income shares and unemployment. Next, it applies the model to a quantitative evaluation of capital as an origin of wage inequality: at the current rate of ...
