In this paper we extend the model of Easley and O’Hara (1992) to allow the arrival rates of informed and uninformed trades to be time-varying and forecastable. We specify a generalized autoregressive bivariate process for the arrival rates of informed and uninformed trades and estimate the...

Since the introduction of the autoregressive conditional heteroskedastic (ARCH) model in Engle (1982), numerous applications of this modeling strategy have already appeared. A common finding in many of these studies with high frequency financial or monetary data concerns the presence of an...

The capital asset pricing model provides a theoretical structure for the pricing of assets with uncertain returns. The premium to induce risk-averse investors to bear risk is proportional to the nondiversifiable risk, which is measured by the covariance of the asset return with the market...

In this paper, we define dynamic and static factors and distinguish between the dynamic and static structure of asset excess returns. We examine the value-weighted market portfolio as a dynamic factor and propose an intuitively appealing procedure to search for more dynamic factors. We find...

Immediately after 1997 the Asian economies were viewed to be catastrophes of financial excess, corporate and political misgovernance, and diminishing returns to over-investment. But they are now freshly restored as the world’s economic powerhouses, just as before the 1997 financial crises they...

The Japanese economy has been underperforming for more than a decade. The average growth rate of real GDP over the past 12 years has been just above 1 percent, and the nominal GDP has been shrinking since 1997 due to inflation. Nominal GDP for 2003 is 4 percent below what it was in 1997. In...

Introduction: A mere decade ago Japan’s financial system, and especially its banking system, was not only the largest but the strongest in the world. Nine of the world’s top ten banks in asset size were Japanese; the Big Four Japanese securities companies were the world’s largest; and its...
