Count models often best describe the nature of data in health economics, but the presence of fixed effects with excess zeros and overdispersion strictly limits the choice of estimation methods. This paper presents a quasi-conditional likelihood method to consistently estimate models with excess...

This paper takes a new approach to testing whether employer learning is public or private. We show that public and private learning schemes make two distinct predictions about the curvature of wage growth paths when there is a job change, because the amount of information transferred to a new...

This paper analyzes a small open economy Ramsey growth model with convex investment costs and a collateral constraint on borrowing. Optimal control methods are used to characterize the dynamics of investment, consumption, and debt. The analysis demonstrates that the economy’s adjustment speed...

The study of bank interest rate spreads is central to our understanding of the process of financial intermediation. Data limitations generally restrict empirical analyses to interest rate spreads that are constructed from bank income statements and balance sheets. In this paper we make use of a...

The class of growth models that incorporate nonrivalry and/or externalities implies that the size (scale) of an economy influences its growth rate. Ample empirical evidence exists to suggest that such implied scale effects are counter-factual. The objective of this paper is to develop a general...

Many researchers believe that the Beveridge-Nelson decomposition leads to permanent and transitory components whose shocks are perfectly negatively correlated. Indeed, some even consider it to be a property of the decomposition. We demonstrate that the Beveridge-Nelson decomposition does not...

We investigate confidence intervals and inference for the instrumental variables model with weak instruments. Wald-based confidence intervals for a structural parameter perform poorly in that the probability they reject the null is far greater than their nominal size. We show that the preactice...
