We study the optimal consumption and portfolio choice problem over an individual's life-cycle taking into account annuity risk at retirement. Optimally, the investor allocates wealth at retirement to nominal, inflation-linked, and variable annuities and conditions this choice on the state of the...

Taxes and microstructure constraints are often cited as possible explanations for why stock prices drop by less than the dividend on their ex-dates. Using a sample of REITs, which have no significant correlation between dividend size and yield, we find that close-to-open ex-dividend price drops...

We study a dynamic asset allocation problem in which stock returns exhibit short-run momentum and long-run mean reversion. We develop a tractable continuous-time model that captures these two predictability features and derive the optimal investment strategy in closed-form. The model predicts...

This paper considers financial, operational, solvency, and performance ratios, in order to detect when there were balance sheets' variations related to the 1994 Mexican currency crisis. Quarterly results for 88 non-financial Mexican companies that survived the crisis are used, and tests for...

The term financial contagion often refers to contagion between countries. However, firms also manifest contagion during financial crises, which can be determined according to operational and financial results. This research studies how 88 private, non-financial Mexican firms got contagion and...

Milton Friedman argued that irrational traders will consistently lose money, won't survive and, therefore, cannot influence long run asset prices. Since his work, survival and price impact have been assumed to be the same. In this paper, we demonstrate that survival and price impact are two...

Conventional time series analysis, focusing exclusively on a time series at a given scale, lacks the ability to explain the nature of the data generating process. A process equation that successfully explains daily price changes, for example, is unable to characterize the nature of hourly price...

Almost all recent US firm commitment IPOs between $20 million and $80 million in proceeds have been charged an underwriting spread of exactly 7%, while in the early 1980s only 25% of IPOs faced such clustering at exactly 7% [Chen and Ritter (2000)]. Such clustering, or specifically, the apparent...

Yes! We study the time-varying risk patterns of value and growth stocks across business cycles. We find that the conditional market betas of value stocks covary positively with the expected market risk premium, and that value stocks are riskier than growth stocks in bad times when the expected...

We examine the extent to which a fund's cash flows are affected by the stellar performance of other funds in its family - and consequences of such spillovers. We show that star performance results in greater cash inflow to the fund and to other funds in its family. Moreover, families with higher...
