Jump risk, time-varying risk premia, and technical trading profits
In this paper we investigate the recently documented trading profits based on technical trading rules in an asset pricing framework that incorporates jump risk and time-varying risk premia. Following Brock, Lakonishok, and LeBaron (1992), we apply popular technical trading rules to the daily S&P 500 index over a long period of time. Trading profits are examined using bootstrap simulation to address distributional anomalies. We estimate a variety of asset pricing models, including the random walk, autoregressive models, a combined jump diffusion model, and a combined model of jump-diffusion ...

Corporate hedging in the insurance industry: the use of financial derivatives by U.S. insurers
In this paper we investigate the extent to which insurance companies utilize financial derivatives contracts in the management of risks. The data set we employ allows us to observe the universe of individual insurer transactions for a class of contracts, namely, those normally through of as off-balance-sheet (OBS). We provide information on the number of insurers using various types of derivatives contracts and the volume of transactions in terms of notional amounts and the number of counterparties. Life insurers are most active in interest rate and foreign exchange derivatives, while ...

Emerging debt and equity markets: an exploratory investigation of integration using daily data
In this paper we examine integration between emerging and U.S. debt and equity markets. We first investigate price changes around significant "events," in this case changes in short-term U.S. interest rates brought about by actions of the Federal Reserve. Second, we estimate the predictability of returns using both domestic and U.S. variables. Finally, we test whether a single latent variable can explain these returns. The evidence suggests that the degree of integration varies with security types and the country of origin. However, these differences between security types become less ...

The buck stops where? The role of limited liability in economics
Over the last few centuries laws have increasingly protected individuals and corporations from liability resulting from bad economic outcomes. This evolution in liability provisions, by many accounts, has significantly influenced both the level and distribution of contemporary economic output as well as the allocation of financial resources in today's financial markets. ; Through a review of an extensive and growing literature, the authors of this article consider how limited liability affects investment, labor, and financing decisions made by individuals and corporations as well as ...

Hedging, financing, and investment decisions: a simultaneous equations framework
The purpose of this paper is to empirically investigate the interaction between hedging, financing, and investment decisions. This work is relevant in that theoretical predictions are not necessarily identical to those in the case where only two decisions are being made. We argue that the way in which hedging affects the firms? financing and investing decisions differs for firms with different growth opportunities. We empirically find that high-growth firms increase their investment, but not their leverage, by hedging. However, we also find that firms with few investment opportunities use ...
