Will the low search cost in the new economy help speed up new product introduction? The usual model of product market search suggests that a low search cost can turn out to have detrimental incentives on innovation and new product introduction as the low search cost erodes firms' market power,...

This paper provides new insight into the relationship between inflation and consumer price setting by examining a large data set of Mexican consumer prices covering episodes of both low and high inflation, as well as the transition between the two. The overall portrait is one in which the...

In this paper, we study the dynamics of innovation financing as a new industry emerges. Specifically, in an environment where the profitability of an industry is uncertain, we consider the dynamics of the adoption of innovations/projects and the relative shares of bank and venture capital...

Aggregate stock prices, relative to virtually any indicator of fundamental value, soared to unprecedented levels in the 1990s. Even today, after the market declines since 2000, they remain well above historical norms. Why? We consider one particular explanation: a fall in macroeconomic risk, or...

This paper suggests a solution to the puzzling finding documented in Moskowitz and Vissing-Jorgensen (2002) that the return to an index of private equity is equal to the return to the CRSP index of public equity even though investment in private firms is substantially riskier. It presents an...

The main contribution of this work is to provide a dynamic general equilibrium model of asset allocation, allowing to reconcile economic theory with several puzzling contradictions recently pointed out in the literature: (i) the asset allocation puzzle, (ii) the observed time-variation in...

Financial economists have long been interested in the empirical relation between the conditional mean and conditional volatility of excess stock market returns, often referred to as the risk-return relation. Unfortunately, the body of empirical evidence on the risk-return relation is mixed and...

We quantify the effect of financial leverage on stock return volatility in a dynamic general equilibrium economy with debt and equity claims. We study the effects of financial leverage on the market portfolio, and on a small firm with idiosyncratic and market risk. In an economy with both a...

Value stocks have higher average returns than growth stocks. At the same time, the duration of value stocks' cash flows is considerably shorter than that of growth stocks. We show that when investors can fully distinguish short- and long-run consumption risk components of dividend growth...
