This paper is concerned with growth patterns of US health care expenditures. Within a representative sample of OECD countries, we lay out a growth accounting exercise for health care expenditures to assess the influence of several explanatory variables. Our analysis demonstrates that the...

In this paper we consider a sequential trading economy with incomplete financial markets and a finite number of infinitely lived agents. We propose a specification of agents' budget sets and show that such specification features several desirable properties. We then establish the existence of an...

In this paper we are concerned with the performance of stock option contracts in the provision of managerial incentives. In our simple framework, we restrict the space of contracts available to the principal to those conformed by a fixed payment and a call option on the firm’s stock. As...

equilibria in models with heterogeneous agents and market frictions. This method is based upon a convergent operator over an expanded set of state variables. The fixed point of this operator defines the set of all Markovian equilibria. We study approximation properties of the operator as well as...

Price markups are highly correlated with stock market values, whereas other financial measures of profitability exhibit much less variability and are weakly correlated with stock values. We propose a variant of the neoclassical growth model to study the role of innovation, price markups, and...

En este trabajo realizamos un estudio empírico de los efectos macroeconómicos de la integración europea en las incorporaciones que han tenido lugar entre 1970 y 2000. Para ello investigamos los efectos de la integración sobre distintas variables de la economía real. Nuestros resultados...

This paper considers a simulation-based estimator for a general class of Markovian processes and explores some strong consistency properties of the estimator. These results are of interest for various kinds of simulation-based estimation methods typically used in economics and finance. The...

This paper studies the pricing of money in an infinite-horizon economy with heterogeneous agents, incomplete financial markets and arbitrary borrowing restrictions. Purchases of the consumption good are subject to a cash-in-advance constraint. Under general conditions I show that the price of...
