This study develops a multi-factor framework where not only market risk is considered but also potential changes in the investment opportunity set. Although previous studies find no clear evidence about a positive and significant relation between return and risk, favourable evidence can be...

The risk return relationship is analysed in bivariate models for return and realised variance(RV) series. Based on daily time series from 21 international market indices for more than 13 years (January 2000 to February 2013), the empirical findings support the arguments of risk return tradeoff,...

This paper approximation errors are introduced in a Luca (1978)-type model to reflect model uncertainty. The purpose is twofold. First, the rational investor is allowed to take model uncertainty into account when asset prices are determined. Second, the statistical degeneracy, common to most...

Asset prices have been found to respond to unpredicted changes in macroeconomic variables in a number of studies. This paper focuses on the relationship between economic factors and the stock market for a small open economy, namely Canada. Exchange risk is observed to have a significant impact...

We derive new estimates of total wealth, the returns on total wealth, and the wealth effect on consumption. We estimate the prices of aggregate risk from bond yields and stock returns using a no-arbitrage model. Using these risk prices, we compute total wealth as the price of a claim to...

This paper explores the effects of price limits on the Chinese A-share stock markets during financial crises. A Logit regression model is estimated to investigate the characteristics of stocks that hit the price limits more frequently under economic turmoil. It is found that the price limit...

Short sellers are routinely blamed for destabilizing stock markets by exacerbating deviations from fundamental values. In response, regulators periodically impose short sale constraints aimed at preventing excessive stock market declines. One explanation is that policy makers regard short...

This paper aims at testing for time-variations in herd behavior in stock markets. In particular, we analyze how investors’ behavior differs between times of market turmoil and tranquil trading periods. Thereby, we take into account herding within a certain market as well as international...

This study of the co-movements of the transaction prices and trading volumes reveal that the mean correlation of prices, and trading volumes alike, among different housing sub-markets increases during the market boom. After a financial crisis, the correlations drop dramatically and stay low. The...

This paper examines the extent to which individual investors provide liquidity to the stock market, and whether they are compensated for doing so.We show that the ability of aggregate retail order imbalances, contrarian in nature, to predict short-term future returns is significantly enhanced...
