The theoretical structure of producer willingness to pay estimates

This article analyzes the theoretical underpinnings of producer willingness to pay (WTP) for new inputs. In addition to conceptualizing the producer WTP function, we derive its comparative statics and show how these properties can be used to estimate quantities demanded or supplied and price elasticities. We also discuss implications of the comparative statics.     

Improving Skewness of Mean-Variance Portfolios

Abstract

The widely accepted belief that asset returns and insurance product line margins are not normally distributed has motivated the use of skewness (or higher than second-order moments) in the context of optimal risk-reward portfolio allocation. Here we propose an optimization-based methodology to substantially improve the skewness of portfolios in the mean-variance efficient frontier. Unlike other related methods, the proposed methodology is very intuitive, noniterative, and simple to implement, and it can be readily and efficiently carried out using state-of-the-art optimization solvers. These characteristics should be very appealing to risk managers.     

The spillover effects of biofuel policy on participation in the conservation reserve program

This paper studies the spillover effects of rising biofuel production on participation in the Conservation Reserve Program. Landowner participation decisions are modeled using a real options framework. We develop a land use decision model that captures biofuel-driven structural changes in market demand and derive threshold conditions that trigger participation in the program. We then quantify the impacts of biofuel production on participation at both the national and state levels using Monte Carlo simulations. The model is also used to analyze how changes in the persistence of the biofuel production boom and in the volatility of farming returns affect conservation participation decisions. Policy implications of the results are discussed.     

An investigation of ingratiation as a career management strategy: evidence from Singapore

In spite of the recognition that career politics, and therefore ingratiation, is widely used to manage careers, there is a dearth of empirical studies on ingratiation as a career management strategy. Consistent with Ferris and Kacmar's (1988) suggestion, the study reported here investigated the conditions (defined by situational variables, career concerns and personality variables) under which ingratiation is used as a career management strategy. Data were obtained through a structured questionnaire from professional employees (N = 214) in public and private sector organizations in Singapore.

Factor analysis of the 21-item career concerns scale revealed four solutions representing internal and external career concerns. The results of the hierarchical regression revealed that situational variables explained most of the variance in ingratiation, followed by career concerns and personality variables. Among the individual variables, task ambiguity, supervisor reward power, managerial responsibility and need for achievement were significant while personal success approached significance. Internal career concern of autonomy development was unrelated to ingratiation. Of the interaction terms, only supervisor reward power and Machiavellianism approached significance. Directions for future studies are suggested.     

The effect of commute time on racial earnings inequality: a case study of the Houston metropolitan statistical area

Data from the United States Census confirm a substantial increase in the racial earnings gap between 1980 and 1990. This paper examines data on whites and non-white wage and salary incomes in Houston TX for 1980 and 1990. Data on time travelled to work is used to simulate what would be the impact of shorter commute times on earnings inequality. The central finding is that a reduction in travel time from residence to work would cause a very small reduction in racial earnings and income inequality. This suggests that advances in urban transportation policy alone are not sufficient to solve the problem of racial earnings inequality.     

Classical error pairs and the Bayesian prior

Summary We have attempted to show the way in which Bayesian and classical approaches are both similar and divergent. The vehicle for discussion, primarily, involved considerations of cost consequences, planning horizons and numbers of alternatives. In turn, these variables were related to the statistical problem continuum, with classical and Bayesian approaches at opposite ends of the scale. By relating problem variables to this continuum, the question of which approach is most appropriate in a particular situation can be more readily resolved.     

Prostitution services: an exploratory empirical analysis

This study provides an empirical analysis of the market for some male prostitution services in the UK. Flexible working hours, part-time working, and multiple job holding are considered as important labour market characteristics in this service sector. Statistical models helping explain the provision of a deviant and a more mainstream sexual service is reported, utilizing cross-section data drawn from individual prostitute advertisements. The significance of various declared intrinsic endowments of the prostitutes are examined in relation to the offer of these services, including age, ethnicity, physique, and masculine demeanour.     

The Emergence of Second‐Tier Auditors in the US: Evidence from Investor Perceptions of Financial Reporting Credibility

We examine changes in the association between auditor type (Big 4, Second‐Tier, and Other non‐Big 4) and perceived financial reporting credibility in the wake of events (e.g., Andersen's failure, the implementation of SOX, creation of the PCAOB, etc.) which led to significant growth in Second‐Tier client portfolios and increased scrutiny of Second‐Tier audit practices. Our results reveal that financial reporting credibility of Second‐Tier clients was lower than that of Big 4 clients and was indistinguishable from that of Other non‐Big 4 clients pre‐Andersen. However, post‐Andersen, we find that financial reporting credibility of Second‐Tier clients is higher than that of Other non‐Big 4 clients and is indistinguishable from that of Big 4 clients. We expect that our results will be of interest to regulators, both in the United States and in the European Union, who have expressed concerns about the current state of competition in the audit market, management and boards of directors that are contemplating switching to a Second‐Tier audit firm, and academics investigating quality differences among audit firm types.
