What Cost of Capital Should You Use? The Market Has an Answer

The most widely used means of estimating a company's cost of equity capital is the Capital Asset Pricing Model (CAPM). But as a growing number of academics and practitioners have suggested, use of the CAPM produces estimates that often fail to reflect the risks of the companies as perceived by current and potential investors. The authors' work, together with other research, also suggests that the cost of equity produced by the CAPM is often too high. To the extent this is so, companies are discounting investment projects at rates of return that may be leading them to pass up value‐adding opportunities. The authors advocate the use of a simple and practical alternative to the CAPM that does not use either an assumed market risk premium or a beta. It uses instead an equity premium that is implied by the current market price of a company's stock and, as such, is implicitly derived from investors' assessments of the firm's risk that are reflected in that price. More specifically, the alternative approach solves for the internal rate of return that equates the present value of expected future cash flows to the current market price. In support of this approach, studies have shown that such market‐implied measures are better predictors than CAPM‐based estimates of future stock returns, both at the individual‐firm and aggregate market levels.     

How widespread are nonlinear crowding out effects? The response of private transfers to income in four developing countries

This article investigates the relationship between household income and private transfers received in developing countries. If private transfers are unresponsive to household income, there is less likelihood of expansions in public social security crowding out private transfers. Most literature finds that private transfers are unresponsive, but this may be because responses have been obscured by the methods that ignore nonlinearities. Threshold regression techniques find such nonlinearity in the Philippines and scope for serious crowding out, with 30–80% of private transfers potentially displaced for low-income households (Cox et al., 2004). To see if these nonlinear effects occur more widely, semiparametric and threshold regression methods are used to model private transfers in four developing countries – China, Indonesia, Papua New Guinea and Vietnam. The results reported in this article suggest that nonlinear crowding out effects are not important features of transfer behaviour in these countries. The transfer derivatives under a variety of assumptions only range between 0 and ?0.08.     

Estimating choice models in data-sparse environments: Taking advantage of perceived similarity

Research suggests that choice models conditioned on correctly identified consideration sets outperform choice models conditioned on the awareness set (Hauser, 1978; Roberts and Lattin, 1991). However, in data-sparse environments, where purchase history information is not available or not relevant, choice models conditioned on the consideration set often yield nonunique or nonsignificant solutions. In these environments, we propose the use of similarity information to improve the performance of choice models. Support for this position is found in an empirical application involving automobiles.     

Alternative Retirement Income Arrangements and Lifetime Income Inequality: Lessons From Australia

This paper examines the implications for lifetime income equality of alternative retirement income arrangements, using the Australian scheme as a benchmark. In Australia, the pay-as-you go financed age pension is means-tested and thereby provides a contrast with those countries where part or all of a basic pension is paid to all aged persons. Many governments are considering an increase in the level of means-testing. The results show that the introduction of a universal pension coupled with significant changes and simplifications to the structure of taxation and superannuation have little effect on the redistributive impact of the tax structure in a life cycle framework. The presence of means-testing appears to have no significant effect on life-time inequality. The results suggest that it is possible to eliminate complexities from the system providing retirement benefits without having any deleterious effect on equity.

Insider Ownership,Risk, and Leverage in REITs

We investigate the relative importance of managerial entrenchment and incentive alignment as indicated by REIT risk-taking. The two theories make contradictory predictions about the sign of the relation between insider ownership and risk. We test for the possibility of diminishing entrenchment returns to insider ownership. Empirical results for equity and asset betas soundly reject linear models in favor of nonmonotonic relations with reversals at insider ownership of 36%. Up to that point, increasingly entrenched insiders mitigate their own risk aversion. Above 36%, incentive alignment emerges as managers become more substantial owners. Leverage declines at an accelerating rate above 20% insider ownership. Together these results suggest a shift in the composition of risk, from leverage risk to asset risk, reflecting comparative advantage and a crossover in the relative monitoring costs of debt and equity. Problematically for linear models, the coefficient of insider ownership is not significant for most risk measures, producing the misleading appearance of no relation between insider ownership and risk. Institutional ownership is significantly negatively related to leverage. Thus incentives are aligned between insiders and institutional owners at insider ownership above 20%.
