It has long been recognized that worker wages and possibly productivity are higher in large firms. Moreover, at least since Schumpeter (1942) economists have been interested in the relative efficiency of large firms in the research and development enterprise. This paper uses longitudinal...

El principal objetivo de este trabajo ha sido analizar los principales determinantes de las actividades innovativas en la industria manufacturera chilena durante la segunda mitad de los años noventa. Los resultados confirman las principales hipótesis acerca de la importancia del tamaño de la...

We develop and test a model of the patenting and R&D decisions of an innovating firm whose scientist-employees sometime quit to join or start a rival. In our model, the innovating firm patents to protect itself from its employees. We show theoretically that the risk of a scientist's departure...

One of the important public policy issues in science and technology is to ascertain if and how firms' investments in research and development (R&D) contribute to technical progress at firm and industry levels. Griliches (1979) made a pioneering contribution to our understanding of economic...

This paper addresses the relationship between individual perceptions and the uses of a business language. Perceptions are modeled explicitly, and are not common knowledge. A business language enables individuals with different perceptions to trade. I present a formal criterion for faithfulness...

This paper explores the quantitative impact of the Baby Boom on stock and bond returns. It constructs a neoclassical growth model with overlapping generations, in which agents make a portfolio decision over risky capital and safe bonds in zero net supply. The model has exogenous technology and...

We extend the standard specification of the market price of risk for affine yield models of the term structure of interest rates, and estimate several models using the extended specification. For most models, the extended specification fits US data better than standard specifications, often with...

This paper develops a search-theoretic model of the cross-sectional distribution of asset returns. It abstracts from risk premia and focuses exclusively on liquidity. A float-adjusted return model (FARM) is derived, explaining the pricing of liquidity with a simple linear formula: In...

In this article we construct a model in which agents exhibit preference for ownership with respect to a durable (house). Ownership is modeled as a continuous function of debt service normalized by the price of the house. We study the utility optimization problem of an investor not endowed with...

Using a generalized cross-spectral approach, we propose a model-free omnibus statistical procedure to check whether the direction of changes in an economic variable is predictable using the history of its past changes. A class of separate inference procedures are also given to gauge possible...
