Hypothetical Bias Reconsidered: Payment and Provision Uncertainties in a Threshold Provision Mechanism

We extend research on the consequentiality of stated preference choices to a threshold provision mechanism for public goods. We develop a simple theoretical model of option price to analyze how option price varies with payment and provision uncertainty. We explore whether threshold provision contributions are similarly influenced by payment and provision uncertainty using an induced value contribution experiment. Results suggest that: (1) the probability of payment has a negative effect on contributions; (2) the probability of provision has a positive effect on contributions. We offer subjective beliefs regarding payment and provision as a plausible systematic explanation for hypothetical bias.     

MARRIAGE,DIVORCE, AND ASYMMETRIC INFORMATION

We use data on people's valuations of options outside marriage and beliefs about spouses' options. The data demonstrate that, in some couples, one spouse would be happier and the other spouse unhappier outside of some marriages, suggesting that bargaining takes place and that spouses have private information. We estimate a bargaining model with interdependent utility that quantifies the resulting inefficiencies. Our results show that people forgo some utility in order to make their spouses better off and, in doing so, offset much of the inefficiency generated by their imperfect knowledge. Thus, we find evidence of asymmetric information and interdependent utility in marriage.     

Comovement in GDP trends and cycles among trading partners

It has long been recognized that business cycle comovement is greater between countries that trade more intensively with one another. However, nations face shocks to both the cyclical and trend components of their GDP series. Contrary to the result for cyclical fluctuations, we find comovement of shocks to the trend component of real GDP is weaker among countries that trade more intensively with one another. We simulate changes in ten-year output growth correlations corresponding to the estimated effects of trade and show that the impact of trade on trend comovement is quantitatively more important than its effect on cyclical comovement.     

Binding constraints to productive investment in Malawi: A modified HRV framework

The paper applies a modified Hausmann, Rodrik, and Velasco (HRV) growth diagnostics framework to analyse Malawi's growth challenges. The study finds five critical binding constraints affecting productive investment and output growth in Malawi. These include land administration, taxation, customs and trade regulations, political governance, and cost‐of‐finance. Land constraints are evidenced by highly urban and rural population growth, an inverse co‐movement between the rural population and investment per capita, and low land administration indices. Tax constraints are evidenced by the negative growth of investment per capita. Customs and trade regulations constraints are evidenced by nontariff measures, such as high costs and the time it takes to export and import. Political governance constraints are evidenced by rising government debt and the low score on transparency, accountability, and corruption based on the World Bank's Public Transparency Scale. Lastly, high cost‐of‐finance constraints are evidenced by monetary policy challenges, such as high real interest rates, inflation rate, uncompetitive exchange rate, and foreign aid ineffectiveness. Therefore, we recommend that the formulation of crucial policy strategies to alleviate these five significant binding constraints be encouraged. The government should base such an approach to sound growth therapeutics that fully account for each challenge's root causes.     

The Role of Nonattenuated Rights in Positive Economics: A Critical Appraisal

This article assesses the institutionalist elements of Friedrich Hayek's neoliberal political economy by presenting his views on the entangled relations between the state and markets in capitalism. Through the analysis of Hayek's work, the article contributes to further consolidating the view that neoliberalism is an ideological project of institutional transformation which, despite some enduring myths, has an irreplaceable role for a state with many important functions in a more limited democracy. Markets, for their part, are politically contested social constructions that depend on previous non-market institutions for their existence and legitimation. This paper argues that Hayek's work corroborates this institutionalist claim.     

An alternative definition of individual bioequivalence

Several definitions of individual bioequivalence of two formulations of a medical treatment (drug) have been proposed recently. These definitions attempt to adapt the criterion of average bioequivalence, which would be deficient if substantive treatment heterogeneity were present. In some of the proposed definitions, relatively large differences of means can be compensated by differences in the measurement-error variances. We propose a definition based on a simple latent-variable model which overcomes this anomaly and need not involve the U.S. Food and Drug Administration's 80/125 rule. Our approach is based on a moment-matching estimator of the discrepancy between the outcomes underlying the subjects' responses. The distribution of this estimator is a linear combination of independent χ² variates; asymptotically, it can be approximated by a normal distribution. Evidence of individual bioequivalence corresponds to rejecting the hypothesis that the discrepancy is greater than a specified threshold. The approach is illustrated by reanalysing two bioequivalence trials.     

Marketing Concept Manifestations in Fiji Enterprises: Confirming the Link to Organizational Competitiveness

ABSTRACT

This paper proposes an integrative view of the marketing concept (i.e., the ability to understand and satisfy customers) and examines its prevalence and effect on competitiveness in organizations operating in an isolated and less economically developed country. The marketing concept manifests as marketing expertise, market orientation, and externally directed organizational values. Based on a sample of 86 firms operating in Fiji, the results indicate that these three mechanisms promote organizational competitiveness, thus supporting the universality of the marketing concept. These findings confirm the important role of the marketing concept in the competitiveness of firms in a less developed economy.     

INTERFUEL SUBSTITUTION: A META‐ANALYSIS

Abstract This paper provides the first meta‐analysis of the interfuel substitutability literature. The sample includes 47 studies of interfuel substitution in the industrial sector, in manufacturing industry or manufacturing sub‐industries, or in the macro‐economy of a variety of developed and developing countries. Meta‐regressions are estimated for the six shadow elasticities of substitution between coal, oil, gas and electricity. I find that at the level of the industrial sector as a whole the oil–coal, oil–gas, oil–electricity and gas–electricity shadow elasticities of substitution are significantly greater than unity. The remaining elasticities – between coal and gas and coal and electricity – are insignificantly different from unity or zero due to their large standard errors. Substitution possibilities seem more constrained at the macro level and less constrained at lower levels of aggregation. Estimates of the elasticities of substitution from cross‐section regressions are generally largest whereas fixed effects panel estimates are intermediate in magnitude, and time‐series estimates are mostly much smaller. In order to obtain more precise and less biased estimates of long‐run elasticities of substitution, there is a need for additional primary studies using large samples and/or the between estimator which econometric research suggests is likely to provide the best estimates of long‐run elasticities.     

Monthly wood supply behavior of associated forest owners in Austria—Insights from the analysis of a micro-econometric panel

This paper examines the wood supply from non-industrial private forest owners in Austria. The main novelty of this study is threefold. First, the underlying dataset is based on monthly wood supply. This enables an analysis of seasonal supply behavior, which is found to be different in relation to the size of the forestland. Second, it represents an original study with a dataset from a Central European country whose forest owners are apparently much more fragmented than their Scandinavian or North American counterparts. And third, the study introduces a windfall variable that effectively corrects for a market-relevant storm event. With respect to methodology, a random effects Tobit model is applied. Additionally, a Chamberlain-like term is included in the regression to deal with a possible bias generated through the correlation of regressors and unobserved heterogeneity.     

Service level agreements: An essential aspect of outsourcing

This paper notes and explains the increasing use of service level agreements (SLAs), stresses their importance to insourcing and outsourcing relationships, proposes a taxonomy of service attributes, and recommends a hierarchical methodology for constructing SLAs. Evidence from interviews and examination of SLA documents suggests that well-designed SLAs contribute to fruitful relationships between business partners. The proposed methodology and taxonomy will simplify the time-consuming tasks of writing and negotiating SLAs. SLAs have not received academic attention proportionate to their commercial importance. Research to ascertain whether SLAs are used effectively and to seek better expression of business requirements in an SLA is appropriate.
