Unit roots in output, an exponential 2% rate of convergence and no change in the underlying dynamics of output seem to be three stylized facts that can not go together. This paper extends the Solow-Swan growth model allowing for cross-sectional heterogeneity. In this framework, aggregate shocks...

It is well known from time series analysis that shocks to aggregate output have very persistent effects. This paper argues that the relation between the expected growth rate of a firm and its size\ provides a microfoundation for such aggregate persistence. The empirical evidence indicates that...

We claim that the stock market encourages business creation, innovation, and growth by allowing the recycling of "informed capital". Due to incentive and information problems, new start-ups face high flotation costs. Sustaining a tight relationship with a monitor allows them to postpone their...

The European Community and the US have experienced vastly different unemployment dynamics over the last two decades. This paper investigates whether these differences are due to exposure to different shocks or reacting differently to the same shocks. With the premise of a search theoretic...
