A martingale characterization of the price of a nonrenewable resource with decisions involving uncertainty

This paper presents a general model of nonrenewable resource consumption and exploration decisions involving uncertainty about the time of occurrence of an event such as exhaustion, stock discovery, or a substitute development. The resulting price process is characterized in terms of necessary and sufficient conditions under which the price is expected to rise at a rate equal to, greater than, or less than the discount rate. The general model is illustrated and the price process and the optimal decisions are characterized by examining the three types of uncertainty indicated above.     

Signalling power of special dividends in an imputation environment

The present study examines the impact of the announcement of special dividends for a sample of Australian companies over the period July 1989 to June 2002. The risk‐adjusted price reaction to special dividend announcements from the day before the announcement to the day after the announcement (day ?1 to day 1) is positive and statistically significant, averaging 3.67 per cent. Initial special dividend announcements (4.68 per cent) led to stronger price reaction than special dividend announcements that follow an earlier special dividend (1.51 per cent) in the previous year. The magnitude of price reactions to special dividend announcements is statistically related to the size of the special dividend, the existence of prior special dividend announcements, abnormal cash flow for the year ended after the special dividend announcement, the existence of dividend reinvestment plans (DRP) versus non‐DRP, and a preannouncement effect. Finally, we found strong support for the information content/signalling hypothesis for special dividend announcements that do not participate in DRP and limited support for those associated with DRP.     

Does the threat of takeover affect default risk?

We examine the impact of the threat of takeovers on default risk. Using a sample of 50,189 firm-year observations for US firms over the period 1990–2015, we find that the threat of takeovers has a negative relation with default risk. We use difference-in-difference analysis to address potential endogeneity concerns and propensity score matching to control for self-selection bias. The results are robust to alternative measures of default risk and exclusion of the dot com and financial crisis periods. Our results also hold after controlling for Governance Index and Entrenchment Index. We identify improvement in performance and earnings quality in response to the threat of takeovers as channels underlying our main result. The effect of the threat of takeovers on default risk is more pronounced for firms with opaque information environment and low institutional ownership. Our findings provide important insights for the market for corporate control as a disciplining mechanism in reducing default risk.     

Understanding the variation in estimates of off-farm labour supply elasticities: A meta-analysis

The design of rural development policies and government programmes in support of farm operations and farm households relies on precise estimates of off-farm labour supply elasticities. However, the wide variation in estimates dilutes their power to predict the magnitude of these targeted interventions. We perform a meta-analysis of estimates of off-farm labour supply elasticity to identify systematic factors that influence these estimates. A sample of 137 elasticities is obtained from 43 studies which use data ranging from 1960 to 2012. We examine theoretical assumptions, data availability and empirical specifications, and other study-specific characteristics. Controlling for potential publication bias, we estimate that the elasticity is approximately 0.64 to 0.77. Results of the analysis show that estimates are affected by modelling choices controlling for self-selection and life-cycle elements. However, we found no compelling evidence that study-specific characteristics of off-farm labour supply functions, including various measurements of labour supply, explain variation in the elasticities.
