This paper studies the conditions under which the scarcity of a factor (in particular, labor) encourages technological progress and technology adoption. In standard endogenous growth models, which feature a strong scale effect, an increase in the supply of labor encourages technological...

This paper introduces endogenous and directed technical change in a growth model with environmental constraints. A unique final good is produced by combining inputs from two sectors. One of these sectors uses "dirty" machines and thus creates environmental degradation. Research can be directed...

In this article, we show how to analyse analytically the equilibrium policies and prices in an economy with a stochastic investment opportunity set and incomplete financial markets, when agents have power utility over both intermediate consumption and terminal wealth, and face portfolio...

This paper proposes a dynamic risk-based model that captures the high expected returns on value stocks relative to growth stocks, and the failure of the capital asset pricing model to explain these expected returns. To model the difference between value and growth stocks, we introduce a...

This paper examines the co-movement among stock market prices and exchange rates within a three-country Centre-Periphery dynamic equilibrium model in which agents in the Centre country face portfolio constraints. In our model, international transmission occurs through the terms of trade, through...

Among the most important pieces of empirical evidence against the standard representative agent, consumption-based asset pricing paradigm are the formidable unconditional Euler equation errors the model produces for cross-sections of asset returns. Here we ask whether calibrated leading asset...

This paper derives a tax-adjusted discount rate formula with a constant proportion leverage policy, investor taxes, and risky debt. The result depends on an assumption about the treatment of tax losses in default. We identify the assumption that justifies the textbook approach of discounting...

The empirical performance of macroeconomic exchange rate models is more than disappointing. This dismal result is also reflected in the forecasting capabilities of professional analysts: all in all, analysts are not in a position to beat naïve random walk forecasts. The root for this deficient...

In this paper we document new results regarding the forward premium puzzle. The often found negative correlation between the expected currency depreciation and interest rate differential is, contrary to popular belief, not a pervasive phenomenon. It is confined to developed economies, and here...

We test for the pricing of exchange rate and foreign inflation risk in equities. Our tests are motivated by the empirical implications of the models of Solnik (1974b) as revised by Sercu (1980), Grauer, Litzenberger, and Stehle (1976), and Adler and Dumas (1983). Both exchange rate and foreign...
