CONVERTIBLE DEBT AND RISK‐SHIFTING INCENTIVES

I argue that convertible debt, in contrast to its perceived role, can produce shareholders’ risk‐shifting incentives. When a firm's capital structure includes convertible debt, every investment decision affects not only the distribution of the asset value but also the likelihood that the debt will be converted and thereby the distribution of the firm's leverage. This suggests that managers can engage in risk‐increasing projects if a higher asset risk generates a more favorable distribution of leverage. Empirical evidence using 30 years of data supports my argument.     

Welfare Migration: Is the Net Fiscal Burden a Good Measure of its Economic Impact on the Welfare of the Native-Born Population?

Migration of young workers (as distinct from retirees), evenwhen driven in by the generosity of the welfare state, slowsdown the trend of increasing dependency ratio. But, even thoughlow-skill migration improves the dependency ratio, it neverthelessburdens the welfare state. Recent studies by Smith and Edmonston(1977), and Sinn et al. (2003) comprehensively estimate thefiscal burden that low-skill migration imposes on the fiscalsystem. However an important message of this paper is that inan infinite-horizon set-up, one cannot fully grasp the implicationsof migration for the welfare state, just by looking at the netfiscal burden that migrants impose on the fiscal system. Inan infinite-horizon, overlapping generations economy, this netburden, could change to net gain to the native born population.(JEL F22, H3, J10)     

The St. Petersburg paradox and capital asset pricing

Durand (J Finance 12:348–363, 1957) shows that the classical St. Petersburg paradox can apply to the valuation of a firm whose dividends grow at a constant rate forever. To capture a more realistic pattern of dividends, we model the dividend growth rate as a mean reverting process, and then use the capital asset pricing model to derive the risk-adjusted present value. The model generates an equivalent St. Petersburg game. The long-run growth rate of the payoffs (dividends) is dominant in driving the value of the game (firm), and the condition under which the value is finite is less restrictive than that of the standard game.     

Optimal International Taxation and Growth Rate Convergence: Tax Competition vs. Coordination

Optimal international taxation and its implications for convergence in long run income growth rates are analyzed in the context of an endogenously growing world economy with perfect capital mobility. Under tax competition (i) the residence principle will maximize national welfare; (ii) the optimal long run tax rate on capital incomes from various sources will be zero in all countries; and (iii) long term per capita income growth rates will be equalized across countries. Under tax coordination, (i) becomes irrelevant while (ii) and (iii) will continue to hold. In other words, optimal tax policies are growth-equalizing with and without international policy coordination.

Becoming a long-distance runner – deriving pleasure and contentment in times of pain and bodily distress

ABSTRACT

This paper indicates the way beginner long-distance runners learn to derive pleasure and contentment (‘runner’s high’) in times of pain and bodily distress. It is based on Becker’s theoretical framework of using marihuana (marijuana) for pleasure. Although pain resulting from long-distance running has been widely explored sociologically, little has been written regarding the process of deriving pleasure from the pain. An ethnographic research design was implemented for three years in two running teams, using a combination of participant observation, semi-structured interviews, and online running websites. Key findings illustrate three coherent stages a novice runner must experience in order to become a long-distance runner and enjoy the pain: (1) learning the proper running technique required to experience positive effects; (2) recognizing the effects of pain and their connection with running; and (3) enjoying the effects of pain caused by running. The paper highlights the way feeling high from long-distance running can be achieved through a process of socialization conveyed by the runner’s peer group. Only if novice runners are persistent and capable of interpreting their bodily sensations as a state of pleasure or relaxation will they be able to continue with distance running.     

Pricing assets with stochastic cash-flow growth

We model the time series behavior of dividend growth rates, as well as the profitability rate, with a variety of autoregressive moving-average processes, and use the capital asset pricing model (CAPM) to derive the appropriate discount rate. One of the most important implications of this research is that the rate of return beta changes with the time to maturity of the expected cash flow, and the degree of mean reversion displayed by the growth rate. We explore the consequences of this observation for three different strands of the literature. The first is for the value premium anomaly, the second for stock valuation and learning about long-run profitability, and the third is for the St. Petersburg paradox. One of the most surprising results is that the CAPM implies a higher rate of return beta for value stocks than growth stocks. Therefore, value stocks must have higher expected returns, and this is what is required theoretically in order to explain the well-known value premium anomaly.     

Persistence Characteristics of Tourism Arrivals to Australia

This paper examines the degree of persistence in international monthly arrivals to Australia by using data disaggregated by tourism‐source countries. We employ two competing models, which are very general in the sense that they include (seasonal and non‐seasonal) unit roots as particular cases of interest. The first model is based on a long‐memory process in the non‐seasonal part of the series along with a short‐memory autoregressive (AR) seasonal structure. The second model is based on a long‐memory process for the seasonal structure of the series, the short‐term evolution being described through a non‐seasonal AR(1) process. Results based on the residuals and forecasting assessment indicate that the second model is preferable in terms of fitting the data. We provide persistence ranking of all countries included in the study and discuss the managerial implications of the main findings. Copyright © 2011 John Wiley & Sons, Ltd.     

Unskilled Migration: A Burden or a Boon for the Welfare State?

As relatively low earners, migrants are net beneficiaries of the welfare state. Therefore, in a static setup, migration may be resisted by the entire native-born population. However, it is shown that in a dynamic setup with a pension system, which is an important pillar of any welfare state, migration is beneficial to all income (high and low) and all age (old and young) groups, when the economy has good access to international capital markets. The pro-migration feature of the dynamic model is weakened and possibly overturned when the economy does not have good access to such markets. In this case, to the extent that factor prices are significantly affected by migration because of low substitution between labour and capital, low-skill native born and possibly also high-skill native born may lose.
