The relation between time-series and cross-sectional effects of idiosyncratic variance on stock returns in G7 countries
This paper suggests that CAPM-based idiosyncratic variance (IV) correlates negatively with future stock returns because it is a proxy for loadings on discount-rate shocks in Campbell*s (1993) ICAPM. The ICAPM also implies that there are important links between the time-series and cross-sectional IV effects. For example, the coefficients on conditional stock market variance and value-weighted average IV obtained from the time-series regressions reflect loadings on stock market returns and discount-rate shocks, respectively; therefore, they should help explain the cross section of stock ...

Equity market volatility and expected risk premium
This paper revisits the time-series relation between the conditional risk premium and variance of the equity market portfolio. The main innovation is that we construct a measure of the ex ante equity market risk premium using corporate bond yield spread data. This measure is forward-looking and does not rely critically on either realized equity returns or instrumental variables. We find strong support for a positive risk-return tradeoff, and this result is not sensitive to a number of robustness checks, including alternative proxies of the conditional stock variance and controls for hedging ...

When do stock market booms occur? the macroeconomic and policy environments of 20th century booms
This paper studies the macroeconomic conditions and policy environments under which stock market booms occurred among ten developed countries during the 20th Century. We find that booms tended to occur during periods of above-average growth of real output, and below-average and falling inflation. We also find that booms often ended within a few months of an increase in inflation and monetary policy tightening. The evidence suggests that booms reflect both real macroeconomic phenomena and monetary policy, as well as the extant regulatory environment.

Transmission of information across international equity markets
This paper provides evidence of transmission of information from the U.S. and Japan to Korean and Thai equity markets during the period from 1995 through 2000. Information is defined as important macroeconomic announcements in the U.S., Japan, Korea, and Thailand. Using high-frequency intraday data, I focus the study on return volatility and trading volume because the implications of new information are much clearer than for returns. I find a large and significant association between emerging-economy equity volatility and trading volume and developed-economy macroeconomic announcements at ...

The immediacy implications of exchange organization
The paper introduces a connection between the needs of exchanges to respond to the immediacy needs of their clientele and the need to manage the credit risks faced by exchange members. Queueing theory is used to represent the opportunity loss suffered by brokers engaging in multiple activities: order-flow origination and its intermediation. The role of market-making locals is depicted as enabling specialization. Brokers focus on originating order flow and locals on fulfilling intermediation needs. The capacity to specialize is constrained by the availability of creditworthy members acting as ...

What tames the Celtic tiger? portfolio implications from a multivariate Markov switching model
We use multivariate regime switching vector autoregressive models to characterize the time-varying linkages among the Irish stock market, one of the top world performers of the 1990s, and the US and UK stock markets. We find that two regimes, characterized as bear and bull states, are required to characterize the dynamics of excess equity returns both at the univariate and multivariate level. This implies that the regimes driving the small open economy stock market are largely synchronous with those typical of the major markets. However, despite the existence of a persistent bull state in ...

Money demand and equity markets
Money demand in part reflects a portfolio decision. As equities have become a significant store of household wealth, it seems plausible that variations in equity markets could affect money demand. We re-specify a standard money demand equation to include stock market volatility and revisions to analyst earnings projections. We find that these equity market variables are statistically significant and reduce the errors from money demand models.
