We propose a measure of capital market integration arising from a conditional regime-switching model. Our measure allows us to describe expected returns in countries that are segmented from world capital markets in one part of the sample and become integrated later in the sample. We find that a number of emerging markets exhibit time-varying integration. Some markets appear more integrated than one might expect based on prior knowledge of investment restrictions. Other markets appear segmented even though foreigners have relatively free access to their capital markets. While there is a perception that world capital markets have become more integrated, our country-specific investigation suggests that this is not always the case.

Domestic investors hold a substantially larger proportion of their wealth portfolios in domestic assets than standard portfolio theory would suggest, a phenomenon called "equity home bias. " In the absence of this bias, investors would optimally diversify domestic output risk using foreign equities. Therefore, consumption growth rates would tend to comove across countries even when output growth rates do not. Empirically, however, consumption growth rates tend to have a lower correlation across countries than do output growth rates, a phenomenon I call "consumption home bias. " In this paper, I discuss these two biases and their potential relationship. I appreciate useful suggestions and comments from three anonymous referees and John Pencavel, the editor. I am also grateful to Michael Adler, Urban Jermann, and Amir Yaron for helpful discussions. Any errors or omissions are my responsibility alone. 1 Do individuals hold the optimal portfolio? Do they do a good job of hedging risks? The answer to these questions are clearly important for understanding the economy. If individuals indeed hedge risk optimally, then resources are allocated to their most efficient uses. If not, then many other questions arise. Why not? What is the explanation for these inefficiencies? And what

Value stocks have higher returns than growth stocks in markets around the world. For the period 1975 through 1995, the difference between the average returns on global portfolios of high and low book-to-market stocks is 7.68 percent per year, and value stocks outperform growth stocks in twelve of thirteen major markets. An international capital asset pricing model cannot explain the value premium, but a two-factor model that includes a risk factor for relative distress captures the value premium in international returns.

The Stock Market’s Reaction………… We find that on average an announcement of rising unemployment is “good news ” for stocks during economic expansions and “bad news ” during economic contractions. Thus stock prices usually increase on news of rising unemployment, since the economy is usually in an expansion phase. We provide an explanation for this phenomenon. Unemployment news bundles two primitive types of information relevant for valuing stocks: information about future interest rates and future corporate earnings and dividends. A rise in unemployment typically signals a decline in interest rates, which is good news for stocks, as well as a decline in future corporate earnings and dividends, which is bad news for stocks. The nature of the bundle — and hence the relative importance of the two effects — changes over time depending on the state of the economy. For stocks as a group information about interest rates dominates during expansions and information about future corporate earnings dominates during contractions. 3 1.

Contagion in equity markets refers to the notion that markets move more closely together during periods of crisis. One of the most interesting aspects of the contagion debate is the disagreement

We estimate and test the conditional version of an International Capital Asset Pricing Model using a parsimonious multivariate GARCH process. Since our approach is fully parametric, we can recover any quantity that is a function of the first two conditional moments. Our findings strongly support a model which includes both market and foreign exchange risk. However, both sources of risk are only detected when their prices are allowed to change over time. The evidence also indicates that, with the exception of the U.S. equity market, the premium for bearing currency risk often represents a significant

We review the international finance literature to assess the extent to which international factors affect financial asset demands and prices. International asset pricing models with mean-variance investors predict that an asset’s risk premium depends on its covariance with the world market portfolio and, possibly, with exchange rate changes. The existing empirical evidence shows that a country’s risk premium depends on its covariance with the world market portfolio and that there is some evidence that exchange rate risk affects expected returns. However, the theoretical asset pricing literature relying on mean-variance optimizing investors fails in explaining the portfolio holdings of investors, equity flows, and the time-varying properties of correlations across countries. The home bias has the effect of increasing local influences on asset prices, while equity flows and cross-country correlations increase

This paper analyzes the integration process of European equity markets since the 1980s. Its central focus is on the role that EMU, and specifically, changes in exchange rate volatility, has played in this process of financial integration. Building on an uncovered interest rate parity condition to measure financial integration, a trivariate GARCH model with time-varying coefficients yields three key results: first, European equity markets have become highly integrated only since 1996. Second, the Euro area market has gained considerably in importance in world financial markets and has taken over from the US as the dominant market in Europe.And third, the integration of European equity markets is in large part explained by the drive towards EMU, and in particular the elimination of exchange rate volatility and uncertainty in the process of monetary unification.
