Standard international real business cycle models are generally unable to replicate the observed comovements of all the main aggregate variables: in particular, they generate low or negative international comovements in output, investment, and labour. I simulated a two-country, two-sector...

The paper constructs credit shocks using data and the solution to a monetary business cycle model. The model extends the standard stochastic cash-in-advance economy by including the production of credit that serves as an alternative to money in exchange. Shocks to goods productivity, money, and...

This paper uses the Triples test of Randles et al (1980) to detect asymmetries in US as well as international GDP fluctuations. The test does not detect any asymmetry in the distribution of the US GDP, which is consistent with previous empirical findings. However, significant asymmetries are...

We argue that more workers choose to switch occupations in booms than in recessions. That is, skill retooling is procyclical. This view is consistent with Lucas and Prescotts (1974) equilibrium search model modified with aggregate shocks and unemployment insurance. Empirical support is found in...

Standard international real business cycle models often generate negative cross-country correlations in labor and investment. The data, however, display positive correlations. This paper studies the effect of real wage rigidity and financial frictions on international comovement. We find that...

A two-sector real business cycle model, estimated with postwar U.S. data, identifies shocks to the levels and growth rates of total factor productivity in distinct consumption- and investment-goods-producing technologies. This model attributes most of the productivity slowdown of the 1970s to...

This paper studies corporate debt structure over the business cycle and its implications for aggregate macroeconomic dynamics. We develop a tractable macro-finance model featuring debt heterogeneity with both secured and unsecured debt. Unlike secured debt, unsecured debt gives the lenders no...
