We study IPOs by focusing on the degree of portfolio diversification of the shareholders taking the company public. We argue that a less diversified shareholder has more to gain from taking the company public and would be more willing to accept a lower price for the sale of its shares, i.e....

A model of profits switches between four regimes with fixed probabilities; the rationally expected profits stream implies the stock market value. This efficient market model is not rejected by UK post-war time-series behaviour of either profits or the FTSE index.

Using an equilibrium asset and option pricing model in a production economy under jump diffusion, we show theoretically that the aggregated excess market returns can be predicted by the skewness risk premium, which is constructed to be the difference between the physical and the risk-neutral...

This paper examines the relationship between the equity premium and the risk free rate at three different maturities using post-1973 data for a panel of seven OECD countries. We show the existence of subsample instabilities, of some cross country differences and of inconsistencies with the...

This paper studies how U.S. monetary policy affects global stock prices. We find that global stock prices respond strongly to changes in U.S. interest rate policy, with stock prices increasing (decreasing) following unexpected monetary loosening (tightening). This impact is more pronounced for...

We study the stock price response to announcements of share purchases by corporate insiders over the period 1994 through 1999. The cross-sectional variability in the response is consistent with a curvilinear relation between firm value and insider ownership, where the value of the firm first...

We propose a theory of supervision with endogenous transaction costs. A principle delegates part of his authority to a supervisor who can acquire soft information about an agent's productivity. If the supervisor were risk-neutral, the principal would simply make the better informed supervisor...

Firms that buy distressed and bankrupt companies or some of these companies’ assets earn excess returns that are at least 1.6 percentage points higher than when they make regular acquisitions. These returns come at the expense of the target firm’s shareholders, while overall wealth gains are...

We present a model where arbitrageurs operate on an asset market that can be hit by information shocks. Before entering the market, arbitrageurs are allowed to optimize their capital structure, in order to take advantage of potential underpricing. We find that, at equilibrium, some arbitrageurs...

Innovative new ventures fail if they cannot attract resources needed to commercialise new ideas and inventions. Obtaining external resources is a central issue for nascent entrepreneurs - people who are in the process of starting new ventures. We argue in this paper that, a way to deal with this...
