This paper reconsiders the conventional use of econometric models, especially identified vector autoregressive models, in guiding monetary policy. The main question I explore is whether these models are seriously flawed because they ignore asymmetries in the business cycles. Toward that end,...

This note explores the robustness of Hamilton's (Econometrica, 1989) two-regime Markov switching model framework for capturing business-cycle patterns. Applying his exact specification to a revised version of real GNP, I find parameter estimates that are similar to those he reported only when I...

Given recent regulatory inquiries into the derivative-trading practices of mutual funds, we examine their detailed option holdings to assess how mutual funds employ options, what funds use options, and how that affects performance and risk. Mutual funds’ use of options appears consistent with...

We relate the performance of mutual fund trades to their motivation. A fund manager who buys stocks when there are heavy investor outflows is likely to be motivated by the belief that the stocks are significantly undervalued. In contrast, when there are heavy inflows, the manager is likely to be...

This study examines the performance of mutual funds managed by firms that simultaneously manage hedge funds. We find that the reported returns of mutual funds in these "side-by-side" associations with hedge funds significantly underperformed those of mutual funds that shared similar fund and...
