This paper examines whether permanent earnings growth, crucial to stock valuation, increased during the last decade as suggested by proponents of the 'New Economy.' Using S\&P 500 earnings for 1951-2000, we do not find strong evidence of either a one-time structural break or gradual change....

When a price limit regime exists for all of the stocks involved in an index, the index return is an aggregate of limited variables and thereby it is restricted to the same limits. We argue that neither a censored nor a truncated distribution model is appropriate for the aggregate return. The...

This paper examines the production aspect of money to bridge between the search-theoretic models and the canonical Walrasian growth models. In this paper, we argue that money can generate real effects via technology choice (high vs. low), we model explicitly the pattern of exchanges to explore...

We study a model with a durable good subject to abrupt, periodic obsolescence, and characterize the optimal purchasing policy. Consumers optimally synchronize new purchases with the arrival of new durable models. Hence, some agents use a "flexible" optimal replacement rule that switches between...

This paper presents new plant-level evidence on the effects of access to international technology diffusion on the demand for skilled workers using data from Investment Climate Surveys performed by the World Bank in Asia and Latin America. Our findings suggest that in Brazil, China and Malaysia...

Two different theoretical treatments of technology diffusion in an economy are examined. The traditional model based on the aggregate production function approach first introduced by Solow (1957) assumes technology is unstructured and arrives as a continuous exogenous flow. This model predicts...

This study investigates interrelated factor demands for a multi-output technology (voice and data output) in the Australian telecommunication industry over a long period of time (1922 through 1983). While a dynamic model would appear to be necessary to investigate disequilibrium associated with...

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 examines the effects that capital inflows have on the financial system in a Diamond-Dybvig environment. Here, an adverse-selection problem arises where short-term capital has the incentive to enter the domestic banking system while long-term capital chooses to stay out. Then,...

This paper investigates whether the presence of financial frictions can help explain the differences in the variability of output and inflation between the Pre- and the Post-Volcker periods. I use a limited participation model with credit market imperfections, in which financial frictions may...
