Doctoral Origins of Contributors to the American Economic Review, 1960-72

Professor Sun concludes that publishing performance, adjusted for differences in the number of Ph.D.'s granted, is not a function of the quality of graduate schools. Larger institutions appear to have an advantage by turning out a larger number of Ph.D.'s, but no correlation was found when the number of contributors to the AER from a school was compared with the rating of its graduate programs.

Economics departments may hope to improve their rating in doctoral programs by producing more Ph.D.'s and encouraging them to contribute to the AER, Professor Sun concludes.     

General equilibrium with trade balance and real interest rate parity

This paper demonstrates, in the context of a two-sector OLG neoclassical growth model, conditions under which international trade in consumption goods alone may be sufficient for the equalization of real returns to physical capital across countries; that is, under which commodity arbitrage is sufficient for real interest rate parity (RIRP). This role for repeated commodity arbitrage is established via a dynamic extension of the factor price equalization (FPE) theorem which is valid at all dates comprising the equilibrium path as well as its steady state. The results are at odds with the conventional view regarding RIRP which arises from open one-sector growth models, in which case steady state trade balance and RIRP are irreconcilable, and are also a contradiction to frequent assertions of lon-run specialization in two-sector frameworks. An equilibrium path for an integrated world economy yields an endogenous, time-variant cone of diversification which implies sufficient conditions for the dynamic paths of a cross-section of economies to exhibit FPE, and hence RIRP with trade balance, at all points in time. These conditions require that the savings rates and initial capital-labor ratios of individual countries do not deviate too significantly from world averages, and that both sectors absorb capital easily. The first of these requirements is sufficient to establish steady state FPE and RIRP in the general specification. The first two requirements are sufficient for the entire equilibrium path to be characterized by FPE and RIRP in a log-linear example.

The use of real options valuation methodology in enhancing the understanding of the impact of climate change on companies

Climate change has in recent years gathered traction on the business, political and social agenda. From the business perspective, research has shown that climate change impacts on company value are uncertain, significant and strategically important. The challenge therefore is for the business community to apply financial valuation models that support the incorporation of the climate change impacts in strategic planning. However, the commonly used discounted cash flow techniques in capital budgeting are seen as failing to address the high levels of uncertainties inherent in climate change impacts. Real options thinking has been touted as having the potential to enhance understanding of these impacts via its direct handling of uncertainty, although not much research has been done to demonstrate this. Using an illustrative case study, this research presents an argument for introducing the real options approach, a new method for valuing options of future strategic action by companies in a setting that exhibits climate change impacts. The objective of this research is to contribute to the literature on strategic tools for addressing climate change and ultimately offer some management insights that can narrow the gap between finance theory and business practice.

A review of personality and performance: Identifying boundaries, contingencies, and future research directions

This article reviews the literature linking the Big Five personality traits with job performance in order to identify the most promising directions for future research. Specifically, we recommend expanding the criterion domain to include internal and external service-oriented behavior as well as adaptive performance. We also review situational moderators of the personality–performance relationship and suggest additional moderators at the task, social, and organizational levels. Finally, we discuss trait interactions and explain why we expect that our capability to predict employee behavior will be considerably improved by considering the interaction among traits.     

Hepatitis B does not explain male-biased sex ratios in China

Oster (2005) argued that parents with Hepatitis B (HBV) have more sons, which explained Asia's “missing women”. Lin and Luoh (2008) show no relationship between gender and mother's HBV. We test for a relationship between paternal HBV and son share and find none.     

Supply Elasticity Estimates for the Sydney Housing Market

This article presents estimates of the supply elasticity for residential property in metropolitan Sydney over the period 1991–2006. Our results suggest that supply is inelastic—less than unity—for all types of housing, although the supply elasticity is relatively larger for strata properties (apartments and flats) than for non‐strata properties (separate and semi‐detached houses, terraces and townhouses). We also find evidence of a significant fall in supply elasticity between 1991–1996 and 2001–2006. When the median time taken by a local council to decide on a development application is included in the supply curve, it is found to have a negative effect on the supply of residential property. However, split‐sample estimates indicate this effect is largely confined to the 1991–1996 period.     

Pension Type and Retirement Wealth

In this article I analyze the effect of a shift from defined-benefit pensions to defined-contribution pensions on retirement wealth. Regressions results suggest that workers with a defined-benefit pension appear to have more retirement resources than those who either have no pension or have a defined-contribution pension, although individual savings is generally insufficient. I use the Health and Retirement Survey (HRS), which contains data on individuals 51 to 61 years of age.     

Operationalizing the interpretive turn: Deploying qualitative methods toward an economics of meaning

In his original essay advocating the interpretive turn in economics, Lavoie makes an explicit argument favoring (1) an economics of meaning and (2) the growth of knowledge through discursive rivalry within the scientific community. This paper contends that within Lavoie's explicit argument is an implicit case for a particular mode of discovery that resists the excesses of formalism common within the economics discipline and instead puts the investigator, the investigator's theoretical lens, and the subject under investigation in close proximity to one another. With the nodal points of this triangulated relationship in closer proximity to one another, an iterative learning process emerges that is itself a source of social scientific discovery. Further, and in connection to this mode of discovery, is the implicit case favoring qualitative research methods that correct the economics discipline's excessive reliance upon quantitative analysis in its empirical investigations that distances the investigator from the subject under investigation. The goal of this paper is to make these implicit arguments explicit.
