An Arbitrage Pricing Model is estimated in which the risk premia vary in proportion to the conditional volatilities of the macroeconomic innovations which follow an autoregressive specification. The conditional volatilities of the macroeconomic innovations exhibit strong time-variation from...

This paper investigates the price discovery process around exchange-initiated trading halts using thirty minute trade intervals on the Montreal Exchange. Trading halt price discovery, and regulatory and specialist effectiveness differ over the three time periods studied. Volatility and measures...

We use intraday quotes and transactions on halted securities that interlisted on the Toronto Stock Exchange and Montreal Exchange to decompose the spreads and examine quote depths. Our results show that order-processing costs differ for trading halts at the open compared to halts during the rest...

Cross-sectional and time-series tests using mimicking portfolios are used to assess the exactness of the APT with(out) a residual market factor. The first factor seems to be sufficient to span the efficient set, whether the model is estimated using (un)conditional variance-co-variance matrices...
