Using data on US manufacturing, I estimate internal returns to scale and external effects for the consumption and investment sectors. I construct panels of data at the industry level and use results of gross output production function estimation to derive implied estimates in a value added...

How does the persistence of earnings change over the life cycle? Do workers at different ages face the same variance of idiosyncratic earnings shocks? This paper proposes a novel specification for residual earnings that allows for an age profile in the persistence and variance of labor income...

In this paper we reassess the evidence on labor income risk. There are two leading views on the nature of the income process in the current literature. The first view, which we call the "Restricted Income Profiles" (RIP) process, holds that individuals are subject to large and very persistent...

This paper considers estimation of a pure equilibrium search model in which all heterogeneity is endogenous and due to information asymmetries, and of variations that allow better fits to the data. Measurement error and heterogeneity in the productivity levels of firms. The model is fit to a...

Credit supply and demand changes are mostly unobserved, thus identifying completely the transmission of monetary policy through the credit channel is unfeasible. Bank lending surveys by central banks, however, contain reliable quarterly information on changes in loan conditions due to bank, firm...

This paper introduces Heckscher-Ohlin trade features into a two-country dynamic stochastic general equilibrium model, and studies the international transmission of productivity shocks through trade in goods. This framework improves upon existing international real business cycle models in that...

This paper develops a real business cycle model characterized by idiosyncratic employment shocks and quantitatively explores the behavior of aggregate variables under the assumptions of complete and incomplete insurance markets. The results show that the model with incomplete markets produces...

Previous work of monetary dynamic stochastic general equilibrium models with nominal rigidity a la Taylor, particularly the Cho-Cooley model, was abandoned in favor of the New-Keynesian analysis due to the model's failure to deliver business cycle statistics that match the U.S. economy along...

Monetary policy has real effects through credit supply and demand, and since these changes are mostly unobserved, the complete identification of the credit channel is generally unfeasible. Bank lending surveys by central banks, however, contain reliable quarterly information on changes in loan...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm-size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business, we show that, by reducing...
