So far, the literature on dynamic stochastic general equilibrium models with energy price shocks uses energy on the production side only. In these models, energy shocks are responsible for only a negligible share of output fluctuations. We study the robustness of this finding by explicitly...

"This paper studies the macroeconomic effects of implicit government guarantees of the obligations of government-sponsored enterprises. We construct a model with competitive housing and mortgage markets in which the government provides banks with insurance against aggregate shocks to mortgage...

"Market imperfections affect virtually every transaction in some way, generating costs that interfere with trades that rational individuals make, or would make, in the absence of the imperfection. Understanding these costs gives us insight regarding the total costs of transactions, where to...

"This paper develops a new and easily implementable necessary and sufficient condition for the exact identification of a Markov-switching structural vector autoregression (SVAR) model. The theorem applies to models with both linear and some nonlinear restrictions on the structural parameters. We...

"Using data on workers' flows into and out of employment, unemployment, and not-in-the-labor-force, I construct transition probabilities between "employment" and "unemployment" that can be used in the calibration of economies such as Krusell and Smith's (1998). I show that calibration in Krusell...
