| Abstract: | We analyze the effects of market microstructure noise on the Fourier estimator of multivariate volatilities. We prove that the estimator is consistent in the case of asynchronous data and robust in the presence of microstructure noise. This result is obtained through an analytical computation of the bias and the mean squared error of the Fourier estimator and con¯rmed by Monte Carlo experiments. |

| Abstract: | This paper illustrates that dealers in foreign exchange markets not only provide intraday liquidity, they are key participants in the provision of overnight liquidity. Dealing institutions receive compensation for holding undesired inventory balances in part from the information they receive in customer trades. These flows can be used to forecast future movements in the exchange rate. Findings suggest that Canadian dealers, as a group and individually, are more likely to provide interday liquidity to foreign rather than Canadian financial customers. Financial institutions operating in multiple price-correlated markets manage their risky positions across markets. An interdependent relationship is revealed between the supply of liquidity provided by non-financial firms and dealing institutions across time, and across markets. |

| Abstract: | American call and put options on the S&P 500 index futures that violate the stochastic dominance bounds of Constantinides and Perrakis (2007) over 1983-2006 are identified as potentially profitable investment opportunities. Call bid prices more frequently violate their upper bound than put bid prices do, while evidence of underpriced calls and puts over this period is scant. In out-of-sample tests, the inclusion of short positions in such overpriced calls, puts, and, particularly, straddles in the market portfolio is shown to increase the expected utility of any risk averse investor and also increase the Sharpe ratio, net of transaction costs and bid-ask spreads. The results are strongly supportive of mispricing. (JEL G11, G13, G14) |
