Job Satisfaction and Quitting Intentions: A Structural Model of British General Practitioners

A structural model of job satisfaction and quitting intentions is estimated using data from a survey of general practitioners in the UK. Previous research has used reduced form models, making the interpretation of coefficients problematic. The use of a structural recursive model helps to clarify the relationships between intentions to quit, overall job satisfaction, domains of job satisfaction and personal and job characteristics. Job and personal characteristics have a direct effect on job satisfaction in addition to their indirect impact through job satisfaction domains. Job satisfaction domains have a direct effect on intentions to quit, in addition to their effect via overall job satisfaction. The structural approach provides a richer interpretation of the role and effect of job characteristics on job satisfaction and intentions to quit than is found in previous research. This is particularly relevant in some public sector labour markets, where the opportunity to alter wages to compensate for the relative advantages and disadvantages of jobs is limited because of national wage bargaining.     

Heredity or Environment: Why is Automobile Longevity Increasing?

Over the past 25 years the longevity of automobiles has increased dramatically. We disentangle the rise in longevity into an embodied or inherent-durability effect and a disembodied effect (driven by the external environment, such as reduced accident rates or reductions in the prices of auto repair parts) and estimate these effects by year from 1950 through 1991. We find that the entire rise in auto longevity is due to some force disembodied from the cars themselves and offer some speculation about the nature of this external environment.     

Canonical valuation of options in the presence of stochastic volatility

Proposed by M. Stutzer (1996), canonical valuation is a new method for valuing derivative securities under the risk‐neutral framework. It is nonparametric, simple to apply, and, unlike many alternative approaches, does not require any option data. Although canonical valuation has great potential, its applicability in realistic scenarios has not yet been widely tested. This article documents the ability of canonical valuation to price derivatives in a number of settings. In a constant‐volatility world, canonical estimates of option prices struggle to match a Black‐Scholes estimate based on historical volatility. However, in a more realistic stochastic‐volatility setting, canonical valuation outperforms the Black‐Scholes model. As the volatility generating process becomes further removed from the constant‐volatility world, the relative performance edge of canonical valuation is more evident. In general, the results are encouraging that canonical valuation is a useful technique for valuing derivatives. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:1–19, 2005     

Selling an opaque product through an intermediary: The case of disguising one's product

This paper models multiple service providers who use an intermediary to sell an opaque product. An opaque product is a product whose identity is concealed from consumers until after purchase. I find that an opaque good may allow finer segmentation of a service provider's customer base, lead to market expansion, and/or reduce price rivalry. However, if there is little brand-loyalty in an industry, an opaque good increases the degree of price rivalry and reduces total industry profit. The paper also discusses issues regarding channel structure and outlines managerial implications of this research.     

Telecommunications Investment and Traffic in Developing Countries: The Effects of International Settlement Rate Reforms

In 1997 the FCC ordered sharp decreases in international settlement rates (bilaterally negotiated telecommunication rates) between the U.S. and other countries. Developing countries, which received about $35 billion in net settlement payments from U.S. carriers between 1985 and 1998, claim that payments finance telecom investment and that reduced rates, and therefore payments, will harm investment. Using a panel dataset of 179 countries from 1985–1998, I find settlement rates negatively correlated with international telecom traffic, suggesting that reduced rates will stimulate traffic. I also find no evidence that payments finance investment as measured by telephone penetration and telecommunications equipment imports.     

Empirical research on the resource‐based view of the firm: an assessment and suggestions for future research

The resource‐based view (RBV) is one of the most widely accepted theories of strategic management. However, to date no systematic assessment of the RBV's level of empirical support has been conducted. In response, a sample of RBV‐grounded empirical articles was analyzed from which it was found that the RBV has received only modest support overall and that this support varies considerably with the independent variable and theoretical approach employed. It is therefore suggested that scholars avoid the tendency to test models reflecting early incarnations of the RBV and instead test those that incorporate its more contemporary theoretical extensions.

Pesticide productivity,host-plant resistance and productivity in China

Pesticides are used as the primary method of pest controf in Asian rice production. Conditions in China have led to demand for high and increasing rice yields, resulting in intensive cultivation and adoption of fertilizer responsive varieties. The consequence has been widespread pest infestations. Many studies have estimated pesticide productivity, but few have estimated the productivity of alternative methods ot pest control, namely host-plant resistance. None have estimated the substitutability between these methods of pest-control. The productivity of pesticides and host-plant resistance, and the substitutability between them is measured using two-stage Cobb-Douglas and translog production functions. Under intensive rice production systems in eastern China, pesticide productivity is low compared to the productivity of host-plant resistance. In fact, returns to pesticide use are negative at the margin. Host-plant resistance is an effective substitute for pesticides and substantial reductions in pesticide use could be achieved, with no loss in rice production, through improvements in host-plant resistance. These results suggest that pesticides are being overused in eastern China and host-plant resistance is being underutilized. Government policies to promote increased pesticides in rice might be ill advised given the low productivity and negative returns, particularly in light of well known negative externalities associated with pesticide use.     

Culture, economic development, and national ethical attitudes

To understand the influence of culture on ethical attitudes, a variety of countries must be compared simultaneously to avoid confounding of cultural dimensions. This study uses data from the World Values Survey to develop a measure of ethical attitudes that shows partial measurement invariance across 44 countries. Regressing the resulting latent means on four cultural dimensions [Hofstede G. Culture's Consequences: comparing values, behaviors, institutions, and organizations across nations. 2nd ed. Beverly Hills, CA: Sage Publications, 2001] and per capita gross domestic product (PCGDP) reveals effects that are not suggested by examining the predictors in isolation, and explains more variance than analysis of the raw means. However, the model does not account for ethical attitudes reported in Brazil, Japan, and the Philippines. In the remaining 41 countries, uncertainty avoidance, power distance, and PCGDP are found to have negative influences on national ethical attitudes.
