This paper estimates a series of shocks to hit the US economy during the Great Depression, using a New Keynesian model with unemployment and bargaining frictions. Shocks to long-run inflation expectations appear to account for much of the cyclical behavior of employment, while an increase in...

This paper proposes and tests a theory of credit-driven asset bubbles which are neutral in their real effects. When a lender such as a government, central bank, or banking sector is willing to lend infinitely against collateral, explosive asset bubbles can form which exactly offset a bubble in...

Several authors have proposed staggered wage bargaining as a way to introduce sticky wages into search and matching models while preserving individual rationality. I evaluate the quantitative implications of such an approach. I feed through a series of estimated shocks from US data into a search...

In modern macroeconomic models it is difficult to obtain explosive price bubbles on assets with positive net supply. This paper shows that it is possible to obtain explosive bubbles in certain situations when assets such as land are used as collateral and lenders are willing to lend freely...

The Diamond-Mortensen-Pissarides search and matching model is the workhorse of labor macro, but it has difficulty in simultaneously matching the cyclical behavior of job loss and vacancies when taken to the data. By completely ignoring frictions in job creation and focusing instead on firm-level...

We estimate a seven-variable-VAR for the U.S. economy on postwar data using long-run restrictions, taking changes in long-run interest rates and inflation expectations into account. We find a strong connection between oil prices and long-run nominal interest rates which has lasted throughout the...

The Ethiopian government initiated the Ethiopian Coffee Trademarking and Licensing Initiative in 2004 for three coffee origins: Sidama, Yirgacheffe and Harar. Following a court case between Starbucks and the Ethiopian government regarding this initiative, Oxfam organized a publicity campaign....

This paper documents the systematic response of postwar U.S. fiscal policy to fiscal imbalances and the business cycle using a multivariate Fiscal Taylor Rule. Adjustments to taxes and purchases both account for a large portion of the fiscal response to debt, while authorities seem reluctant to...

In this paper, I discuss three sets of links which I uncover in the data on aggregate US job and worker flows. Job flows are strongly related to aggregate employment growth, while worker flows are strongly related to employment growth and the unemployment rate. I show that a simple frictionless...
