The Effectiveness of the U.K. Travel Allowance

This paper discusses a method for analyzing the pricing and production behaviour of a mature oligopoly, characterized by stable market shares and well established patterns of price leadership. The oligopoly utilized as an example is the US primary producers of copper. The paper develops three pricing/production strategies which are felt to be most relevant to the US primary producers. While one of these strategies (collusive monopolistic pricing) is more desirable to the oligopoly, the ability of the oligopoly to impose any of the strategies depends upon market conditions and government stockpile intervention. A generalized logit probability model is developed and estimated to indicate the effects of market conditions and government action upon the ability of the oligopoly to impose its desired pricing/production strategies.     

Optimal financial investments for non-concave utility functions

We prove a formula for the computation of optimal financial investments in an expected utility framework with arbitrary (not necessarily concave) utility functions. This extends classical results on optimal financial investments for strictly concave utility functions and is of importance particularly for applications of prospect theory where the utility function has a convex-concave shape.     

Entry and Exchanges of Cost Information

The literature on exchanges of information has ignored firms' entry decisions. Yet, the Federal Trade Commission recently expressed concerns that exchanges of information in business-to-business electronic platforms would adversely impact entry and, thus, consumers. When entry decisions are endogenized in a competitive Cournot model with cost uncertainty, we find results that contrast sharply with current thinking on the welfare consequences of information sharing.     

Comparing Compliance Behaviour of Students and Farmers. An Extra-laboratory Experiment in the Context of Agri-environmental Nudges in Germany

Increasing popularity of economic experiments for policy impact analysis has led to an on-going debate about the suitability of students to substitute professionals as experimental subjects. To date, subject pool effects in agricultural and resource economics experiments have not been sufficiently studied. In order to identify differences and similarities between students and non-students, we carry out an experiment in the form of a multi-period business management game that is adapted to an agri-environmental context. We compare the compliance behaviour of German agricultural students and German farmers with regard to water protection rules and analyse their responses to two different green nudge interventions. The experimental results reveal that the direction of the response to the policy treatments is similar. Even unexpected behaviour could be reproduced by the student sample. Nevertheless, the magnitude of the treatment effects differed between the two samples. This implies that experimenters in the field of agricultural and resource economics could use the subject pool of students to analyse the direction of nudge policies. If predictions should be made about the magnitude effects, we suggest using a professional subject pool.     

Discouraging Rainforest Transformation: An Ex-ante Policy Impact Analysis

Despite extensive efforts made by national and international certification agencies, Indonesian smallholder farmers’ participation in palm oil certification schemes adoption remains low. A fundamental obstacle is the smallholder practice of rainforest transformation into oil palm plantation which is forbidden by the agencies. In this context, we investigate three policies that could lead to a reduction in rainforest deforestation by smallholders: price premium on certified palm oil; the provision of environmental information; contributor recognition. In order to evaluate the influence of the policies ex-ante, we conduct a social dilemma experiment involving rubber and oil palm smallholders in Jambi Province, Sumatra, Indonesia. The findings indicate that the price premium and provision of context-specific environmental information could reduce rainforest transformation. However, a statistically significant effect of contributor recognition was not found.     

‘The capital market is dead’: the difficult birth of index-linked gilts in the UK

This article describes how and why the Thatcher government introduced index-linked gilts in 1981. It outlines the earlier deliberations by the monetary authorities during the 1950s and 1960s on how an indexed government security might help or hinder the fight against inflation. Although these discussions came to nothing, rising inflation and increasing difficulties with managing the gilt-edged market during the 1970s revived interest in the indexation of government securities. Both the Page Commission in 1974 and the Wilson Report in 1980 recommended the introduction of inflation-indexed securities, but the election of the Conservative government in 1979 gave real momentum to their possible issuance. Although Margaret Thatcher was initially opposed to indexation, Nigel Lawson galvanized the Treasury and the Bank of England to work on a scheme to issue index-linked gilts as a means of improving economic performance. The article traces the contentious series of discussions surrounding the possible effects of index-linked gilts on government debt interest costs, on monetary policy and monetary targets, and on the possible ‘crowding out’ of corporate bonds and equities which could not offer a guaranteed real return. Despite teething problems, the introduction of inflation-linked bonds in the UK was deemed a success.     

Athleticism and the reproduction of gender and ethnic marginality

Our paper explores the construction of ethnic and gender identities through sport and physical education, arguing that the social attitudes of women and members of ethnic minorities to sport helps to define their marginal position in society. We analyse the literature with respect to ethnicity, gender and sport within the framework of recent ethnographic research, and show how gender and ethnic factors markedly affect attitudes to sport. The wider implications of these attitudes are examined and related to work, unemployment and marginal social status. Attitudes to sport are seen to be significant in establishing attitudes to leisure as a whole, which is discussed in terms of social reproduction and the state. We extend the notion of marginality to take account of the importance of leisure behaviour in explaining and justifying the status of women and ethnic minorities in society.     

Bürgerversicherung — Die Wirkung von Kopfprämien auf den Arbeitsmarkt

Capitation fees are considered to be an option for a change in funding principles for statutory health care insurance. This paper discusses several models of capitation fees either to be introduced for a part of the population or for all citizens. It analyses the impact of a change in financing health care on the labour market. Therefore microeconomic theory and a QUERU-model is applied. It also considers the issue of presently co-insured dependents.     

Assessing the Reliability of Self‐reported Income Information in Informal Small Business Lending through a Bogus Pipeline Experiment

Coping with asymmetric information plays a major role in successful small business lending. Our purpose is to determine if small business applicants report their income information correctly when requesting a loan. We use a randomised controlled trial bogus pipeline experiment, established during a typical cash‐flow analysis of a bank for small businesses in the Philippines. The bogus pipeline approach is commonly applied in social science and aims to increase the rate of truth telling by informing participants that answers will be verified by a lie detector. The experimental data, which include 243 observations of credit clients that are mainly from the agricultural and food value chain, served to identify asymmetric information. Additionally, debtors’ repayment behaviour for approved loans was observed by the bank. Our results indicate that loan applicants of the treatment group report lower incomes, an effect which is most pronounced in lower income quantile. Our analyses also reveal higher loan delinquencies in the control group.
