How do countries hold their financial wealth? We construct a new database of countries' claims on capital located at home and abroad, and international borrowing and lending, covering 68 countries from 1966 to 1997. We find that a small amount of capital flows from rich countries to poor...

This paper examines the book building mechanism for marketing initial public offerings. We present a model where the underwriter selects a group of investors along with a pricing and allocation mechanism in a way that maximizes the information generated during the process of going public at a...

Recently much progress has been made in developing optimal portfolio choice models accomodating time-varying opportunity sets, but unless investors are unreasonably risk averse, optimal holdings include unreasonably large equity positions. One reason is that most studies assume investors behave...

We examine the implications of portfolio theory for the cross-sectional behavior of equity trading volume. Two-fund separation theorems suggest a natural definition for trading activity: share turnover. If two-fund separation holds, share turnover must be identical for all securities. If...

Typical value-at-risk (VAR) calculations involve the probabilities of extreme dollar losses, based on the statistical distributions of market prices. Such quantities do not account for the fact that the same dollar loss can have two very different economic valuations, depending on business...

This paper analyzes optimal portfolio decisions of long-horizon investors with undiversifiable labor income risk and exogenous expected retirement and lifetime horizons. It shows that the fraction of savings optimally invested in stocks is unambiguously larger for employed investors than for...

In Razin, Sadka and Yuen (1998, 1999a), we explored the policy implications of the home-bias in international portfolio investment as a result of asymmetric information problems in which domestic savers, being 'close' to the domestic market, have an informational advantage over foreign portfolio...

We investigate the portfolio choices of mean-variance-optimizing investors who use sample evidence to update prior beliefs centered on either risk-based or characteristic-based pricing models. With dogmatic beliefs in such models and an unconstrained ratio of position size to capital, optimal...

This lecture outlines an asymmetric information theory of financial instability which describes the fundamental forces which harm both the financial sector and economic activity. This asymmetric information framework is then used to demonstrate that although international capital movements and...
