Valuing the social cost of corruption using subjective well being data and the technique of vignettes

Corruption can have an effect on people's happiness and satisfaction, and therefore, can generate a social cost. However, the perceptions of corruption and satisfaction can also vary across subjects, due to socioeconomic and cultural characteristics. This article studies the differences in the perceptions of corruption and satisfaction across subjects, utilizing the technique of vignettes for the correction of the bias that follows from the differences in the response scale across individuals. The evidence comes from a sample of citizens in Spain, who are asked about their perceptions of corruption and personal satisfaction. The results show that there exists a response scale bias, both for corruption and satisfaction. These results are utilized to approximate the social cost of corruption.     

The Wealth and Information Effects of Insurers' Open Market Stock Repurchase Announcements

This article examines the use of an increasingly popular method of cash disbursement in the insurance industry: stock repurchase programs. Using a sample of stock repurchase announcements between 1981 and 1997, we examine the motivation for stock repurchase, estimate the market reaction to the repurchase announcement, and evaluate the magnitude of the reaction as it relates to particular insurance industry and firm characteristics. We examine the abnormal returns around the announcement day and find a significant positive wealth effect associated with repurchase announcements—a result that is consistent with that of other studies of both nonfinancial and financial firms. However, we suspect that the nature of the insurance product and the highly regulated status of the insurance industry might serve to mitigate the magnitude of an announcement effect. In fact, we find that the effect for all insurers is smaller than that obtained in samples of industrial firms. Finally, we examine the relationships between the magnitude of the announcement effect and various firm characteristics and test the significance of information signaling and Jensen's free cash flow theories in the insurance setting.     

Horizontal innovation-based growth and product market competition

The influence of the intensity of competition in the product market on economic growth is analyzed by developing an endogenous growth model with horizontal innovation. Product market competition is measured by (1 − Lerner index) and depends on both the share of factor inputs in total income and the degree of substitutability across goods. We find that the shape of the relationship between competition and growth can change dramatically according to which proxy of competition is used. We explain our results in terms of the interplay between the resource allocation and the profit incentive effects.     

Hedging multiple price and quantity exposures

We examined the general hedging problem faced by a global portfolio manager or a pure exporting multinational firm. Most hedging models assume that these economic agents hold only a single asset in the spot market and are exposed only to a single source of price–quantity uncertainty. Such models are less relevant to many financial and exporting firms that face multiple sources of risk. In this study, we developed a general hedging model that explicitly recognizes that these hedgers are faced with multiple price and quantity uncertainties. Our model takes advantage of the full correlation structure of changes in spot prices, quantities, and forward prices. We performed simulations of the hedging model for a firm with two pairs of price and quantity exposures to demonstrate potential gains in hedging efficiency and effectiveness. © 2001 John Wiley & Sons, Inc.

A Bayesian Approach to Double Bounded Contingent Valuation

In this paper we propose a Bayesian approach to model double bounded contingent valuation data. The double bounded elicitation method is interpreted as a two tier iterated process in which the subject is allowed to have a second thought about his/her valuation for the environmental good. Prior information is modelled from the answers to the first dichotomous choice question. The model is Quasi-Bayesian (Q-B) in that the prior distribution refers to mean willingness to pay while the likelihood function refers to the proportions of a multinomial distribution. This model is applied to empirical data from a contingent valuation survey involving the valuation expressed by European tourists for access to natural areas in the Canary Islands. Results show that point estimate of consumer surplus computed with the Q-B model does not differ substantially from single bounded model estimation. In addition, double bounded seems to be quite robust to the choice of the prior model of willingness to pay responses. Comparison with open ended suggests that the Q-B model might be useful to control for strategic response and starting point biases.     

The effects of water temperature in aquaculture management

This study examines the impact of water temperature on the optimal management of the ration size and fish weight in off-shore farm aquaculture. A model for the expected returns of the farm is developed which includes a fish growth function influenced by fish weight, the ration size and water temperature. The output transportation cost has an ambiguous effect on the harvesting size, but the impact of water temperature is positive. These results explain empirical evidence in the Canary Islands that unfavourable economic conditions could be overcome by environmental advantageous conditions raising productivity.     

Using the Dagum model to explain changes in personal income distribution

This article studies the evolution of personal income distribution in Spain from 1995 to 2005 using the Dagum model. Dagum's three parameter model (type I) provides a good fitting to empirical income distributions in Spain. Moreover, its parameters can be interpreted as economic indicators of income distribution changes. After studying the economic interpretation of the Dagum model parameters, we analyse the impact of parameter changes on different income percentiles and also on the evolution of inequality in Spain using data from the European Community Household Panel (ECHP) and the European Union Statistics on Income and Living Conditions (EU-SILC).     

Traditiovations: Creating innovation from the past and antique techniques for rural areas

Many agricultural activities are today considered unsustainable for the presence of a large number of externalities involving environment and human health. Almost paradoxically, the future of a modern agriculture seems to be linked also to a return to the past and to a re-appropriation of marginalized, ignored or lost traditions on the base of local cultural heritage and traditional knowledge. These clusters of traditions may represent a precondition to innovate and foster local development generating, thanks also to the support of science and research, innovative practices and techniques deriving from past traditional knowledge or re-invented techniques. Critical analysis and validation of these antique practices by science and research are the prerequisite for the development of Traditiovations: in this article two examples of such Traditiovations are identified and described in which practices and techniques, deriving from historical or past traditional knowledge, show the capability to operate as innovations, despite their apparently obsolete and out-of-date features, in production and management.     

Can Defaults Save the Climate? Evidence from a Field Experiment on Carbon Offsetting Programs

Individual preferences for environmental policies can be influenced by the frame in which choices and decisions are presented. In this paper we present results of a field experiment on the contributions to carbon offsetting programs under two alternative treatments for the default option. The opt-in treatment asked subjects to pay for the policy proposal while the opt-out treatment asked subjects if they wanted to be excluded from payment for the policy proposal. The results show that the frame of the default option had a significant effect on the amount of money paid for the policy proposal. Subjects were more likely to accept the policy proposal if the default option was the opt-out treatment. The results have implications for the design of environmental policies.
