In the CGE based policy modeling literature, especially recent literature on policy modeling for global climate change, nested CES production functions over multiple inputs have been widely used. Although lack of reliable estimates of substitution elasticities for nested structures has been...

We study a class of infinite-horizon nonlinear dynamic economic models in which preferences, technology and laws of motion for exogenous variables can change over time either deterministically or stochastically, according to a Markov process with time-varying transition probabilities, or both....

I estimate the relative magnitudes of worker switching costs and how much the employer switching of experienced engineers responds to outside wage offers. Institutional features imply that voluntary turnover dominates switching in the market for Swedish engineers from 1970--1990. I use data on...

We consider a simple variant of the standard real business cycle model in which shareholders hire a self-interested executive to manage the firm on their behalf. Delegation gives rise to a generic conflict of interest mediated by a convex (option-like) compensation contract which is able to...

In the wake of a severe recession and a sluggish recovery, labor market slack cannot be gauged solely in terms of the conventional measure of the unemployment rate (that is, the number of individuals who are not working at all and actively searching for a job). Rather, assessments of the...

This paper uses data from the Health and Retirement Study to examine retirement and related labor market outcomes for the Early Boomer cohort, those in their mid-fifties at the onset of the Great Recession. Outcomes are then compared with older cohorts at the same age. The Great Recession...

Four years after the beginning of the Great Recession, the labor market remains historically weak. Many observers have concluded that "structural" impediments to recovery bear some of the blame. This paper reviews such structural explanations. I find that there is little evidence supporting...

This chapter assesses how models with search frictions have shaped our understanding of aggregate labor market outcomes in two contexts: business cycle fluctuations and long-run (trend) changes. We first consolidate data on aggregate labor market outcomes for a large set of OECD countries. We...

We assess the extent to which manufacturing decline and housing booms contributed to changes in U.S. non-employment during the 2000s. Using a local labor market design, we estimate that manufacturing decline significantly increased non-employment during 2000-2007, while local housing booms...

This paper studies the cyclical nature of individual income risk using a confidential dataset from the U.S. Social Security Administration, which contains (uncapped) earnings histories for millions of individuals. The base sample is a nationally representative panel containing 10 percent of all...
