Do women and men behave differently in financial asset markets? Our results from an asset market experiment show a marked gender difference in producing speculative price bubbles. Mixed markets show intermediate values, and a meta-analysis of 35 markets from different studies confirms the inverse relationship between the magnitude of price bubbles and the frequency of female traders in the mark...

The theory of general equilibrium with incomplete asset markets (GEI) studies the pricing of securities and commodities, and the interactions of perfectly competitive asset markets and commodity markets in determining consumption and investment. Since financial economics is fundamentally concerned with the pricing of securities, and since macroeconomics is fundamentally concerned with the real ...

In this paper we show that measures of economic uncertainty (conditional volatility of consumption) predict and are predicted by valuation ratios at long horizons. Further we document that asset valuations drop as economic uncertainty rises — that is, financial markets dislike economic uncertainty. Moreover, future earnings growth rates are sharply predicted by current price-earnings ratios. It...

This paper studies the consequences of opening asset markets more often for the properties of asset prices and social welfare. For all reasonable parameter values, increasing trading hours lowers average asset prices, increases unconditional asset price volatility at a given point in time, and decreases unconditional asset price volatility when averaged over the period of time that includes the...

Asset prices and investment were unusually weak throughout the industrial world during the early 1990s. This paper highlights this stylized fact, and connects it with another: in most of the industrial world, asset markets boomed for several years before collapsing around 1989. The paper suggests that asset market bubbles during the late 1980s may have left the industrial world with an ‘asset m...

We investigate how trading frictions in asset markets affect portfolio choices, asset prices and efficiency. We generalize the search-theoretic model of financial intermediation of Duffie, Gârleanu and Pedersen (2005) to allow for more general preferences and idiosyncratic shock structure, unrestricted portfolio choices, aggregate uncertainty and entry of dealers. With a fixed measure of dealer...

We analyze the value of public information in a competitive endowment economy. We provide a global result that an early release of information about the future state of the economy is desired by all agents, or Pareto improving, if agents disagree about the prospect of the economy and asset markets are complete. We further prove that for certain levels of agents’ disagreement, all agents prefer ...
