How common and how persistent are turbulent periods? We address these questions by developing and applying a dynamic dependence framework. In order to answer the first question we estimate an unconditional mixture model of normal copulas, based on both economic and econometric justification. In...

We investigate price discovery over the 24-hour trading day for equities, currencies, bonds, and commodities. Sizable price discovery occurs around the clock for most assets. For a given asset, intraday risk and return distributions are fairly similar, indicating a broadly constant...

Unconditional asset pricing models have generally found it challenging to identify evidence ofrisk aversion. This paper addresses this challenge by examining whether currency portfolios display an intertemporal risk-return relationship. We consider time-varying relations because investors'...

This study investigates the relation between equity flows and returns in Sri Lanka using daily trade data categorized by investor classes. The results show that purchases and sales of domestic and foreign investors, both institutional and individual, are positively related with past returns,...

The aim of this paper is to investigate the behavior of international equity returns and correlations using the discrete-time Markov-switching model and the impact of this behavior on international portfolio choices. We take the perspective of a US-based global investor who considers investment...

This study investigates the ability of market beta, book-to-market equity, leverage, and earnings-price ratio to explain the cross-sectional variation in expected returns in the stock market of Sri Lanka. The sample of the study consists of a total of 88 companies which are listed on the Colombo...

Estimates of U.S. returns differentials have ranged from exorbitant to quite small, in part because of their volatility coupled with the relatively short time series available. We shed light on underlying drivers of returns differentials by presenting a number of decompositions: a by-asset-class...

Bai and Green (2010) argue that existing studies related to international diversification of portfolio mainly concentrated on the risk-returns tradeoffs from the developed markets perspective. Very few literatures available on the behavior on emerging markets, they are scarce in comparison to...

We present evidence of significant bias in event studies that investigate the effect of U.S. monetary policy on U.S. stock prices. To overcome this bias, we propose a new identification method based on the "Impossible Trinity" theory which argues that an economy with a fixed exchange rate and...

The use of conventional augmented CAPM specification in estimating the exchange rate exposure may result in less reliable estimates for, at least, two reasons. First, it does not take into account a few important stylized facts associated with financial time series. Second, one cannot estimate...
