Actual investment performance reflects the underlying strategy of the portfolio manager and the execution costs incurred in realizing those objectives. Execution costs, especially in illiquid markets, can dramatically reduce the notional return to an investment strategy. This paper examines the...

Using a new dataset consisting of six years of real-time exchange rate quotations, macroeconomicexpectations, and macroeconomic realizations (announcements), we characterize the conditional means of U.S. dollar spot exchange rates versus German Mark, British Pound, Japanese Yen, Swiss Franc, and...

The increasing availability of high-frequency asset return data has had a fundamental impacton empirical financial economics, focusing attention on asset return volatility and correlationdynamics, with key applications in portfolio and risk management. So-called "realized" volatilitiesand...

We provide a general framework for integration of high-frequency intraday data into the measurement, modeling, and forecasting of daily and lower frequency return volatilities and return distributions. Mostprocedures for modeling and forecasting financial asset return volatilities, correlations,...

Most high-frequency asset returns exhibit seasonal volatility patterns. This article proposes a new class of models featuring periodicity in conditional heteroscedasticity explicitly designed to capture the repetitive seasonal time variation in the second-order moments. This new class of...

Recent empirical studies have argued that the temporal dependencies in "nancialmarket volatility are best characterized by long memory, or fractionally integrated, timeseries models. Meanwhile, little is known about the properties of the semiparametric inference procedures underlying much of...

This study examines spot and forward exchange rates at a weekly level for four different currencies. It is shown that the vector of forward market forecast errors can be parameterized as a vector moving average (MA) process where the MAcoefficients can be theoretically determined from knowledge...

The forward premium anomaly refers to the widespread empirical finding that the slope coefficient in the regression of the change in the logarithm of the spot exchange rate on theforward premium is invariably less than unity, and often negative. This “anomaly” impliesthe apparent...

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...

The idea that integrates parts of this dissertation is that high-frequency data allow for more precise and robust methods for forecasting financial volatility and elucidating the role of volatility in forming asset prices. Thus, the first two chapters compare the performance of model-free...
