This paper presents a theory explaining the labor market matching process through microeconomic incentives. There are heterogeneous variations in the characteristics of workers and jobs, and firms face adjustment costs in responding to these variations. Matches and separations are described...

Using a dynamic factor model that allows for changes in both the long- run growth rate of output and the volatility of business cycles, we document a significant decline in long-run output growth in the United States. Our evidence supports the view that this slowdown started prior to the Great...

Economic decisions such as occupational and entrepreneurial choices may violate true comparative advantage when economic agents are uncertain about which activity best matches their talents. If relative performance varies over the business cycle (for instance, if downturns affect...

We measure the amount of income insurance and cross-sectional consumption smoothing (lending and borrowing) achieved within subgroups of states, such as regions or clubs, e.g. the club of rich states. We find that there is as much income insurance between, as well as within, regions. By...

The recovery from the last recession has been slower than any other recovery in the post-WWII period both in the US and in many other advanced economies. There is an ongoing debate around the causes of such a slow recovery. Are there any structural factors that are constraining the speed of...

Trade links imply that business cycle fluctuations are transmitted to trade partners. To the extent that fiscal policy can mitigate business cycle fluctuations this implies that there are international interdependencies in stabilization policies. We analyse the role of fiscal policy in...

While this is typically ignored, the properties of the stochastic process followed by aggregate consumption affect the estimates of the costs of fluctuations. This paper pursues two approaches to modelling aggregate consumption dynamics and to measuring how much society dislikes fluctuations,...

We develop and analyse a structural model of efficiency wages founded on reciprocity. Workers are assumed to face an explicit trade-off between the disutility of providing effort and the psychological benefit of reciprocating the gift of a wage offer above some reference level. The model...
