This paper studies the pricing of IPOs in a tractable model in which an investment bank faces some investors with superior information. We show how this can lead to underpricing and we make a number of empirical predictions

We show that a simple equilibrium model with uncertain growth is able to simultaneously generate patterns in implied volatility and risk aversion that are similar to the ones observed in the data. In addition, the model produces an implied pricing kernel that is increasing for particular levels...

We show in a theoretical model that the expected excess return on any asset depends on its covariance not only with the market portfolio, but also with changes in the representative agent's estimate. We test our model using GMM and compare it to the CAPM. The results suggest that adding an...

This paper investigates the extent to which differences in information costs can explain the equity home bias puzzle. In a model where information costs are higher for the Foreign asset than for the Home asset, we show that - if cost functions are convex and the assets have identical return...

A simple portfolio choice model shows that, when a bank's capital is constrained by regulation, regulatory cost (risk weightings) alters the risk and value calculations for the bank's assets. In particular, we find that banks may respond to stricter regulation by increasing the share of...

I use Google News TM to study the relation between news volumes and stock market volatilities. More than nine million stock market-related news stories in English and (Mandarin) Chinese are collected and the dynamics of the news volume and the stock market volatility is compared in both the...

The purpose of this paper is to empirically explore two dimensions of the firm hierarchy of international market-specific linkages using data for Swedish manufacturing firms over the 1997 to 2007 period. First, we investigate the productivity ordering with respect to importing, exporting and...
