An important step in understanding why employment fluctuates cyclically is determining the relative importance of cyclical movements in permanent and temporary plant-level employment changes. If movements in permanent employment changes are important, then recessions are times when the...

The U.S. labor force participation rate rose rapidly during the 1960s, 1970s, and 1980s. It then flattened out in the 1990s, and since 2000 it has fallen, without much sign of an imminent rebound. We attempt to distinguish between cyclical and structural influences on the participation rate by...

A number of industries underwent large and permanent reductions in employment growth at the beginning of this decade. We investigate the sources of these permanent changes in employment growth and what the consequences were for the U.S. economy. In particular, we find that relative declines in...

What is the relative importance of hiring and separation in driving unemployment fluctuations? This paper presents a framework to decompose the moments of unemployment and study the respective contributions of vacancy posting, a measure of firms’ hiring efforts, and separation. Separation...

The low correlation between cyclical unemployment and productivity over the post-war period hides a large sign switch in the mid-1980s: from significantly negative the correlation became significantly positive. Using a search model of unemployment with nominal rigidities and variable labor...

This paper builds a measure of vacancy posting over 1951-2009 that captures the behavior of total--print and online-- help-wanted advertising, and can be used for time series analysis of the US labor market.

This paper develops an analytical framework that helps to quantify the optimal level of international reserves for a small open economy with limited access to foreign capital and subject to natural disasters or terms-of-trade shocks. International reserves allow the country to relieve balance of...
