Willingness to Pay for Reduced Risk of Foodborne Illness: A Nonhypothetical Field Experiment

This paper focuses on estimating willingness to pay for reducing risk of getting foodborne illness using a nonhypothetical field experiment utilizing real food products (i.e., ground beef ), real cash, and actual exchange in a market setting. Respondents were given information about the nature of food irradiation. Single-bounded and one and one-half bounded models are developed using dichotomous choice experiments. Our results indicate that individuals are willing to pay for a reduction in the risk of foodborne illness once informed about the nature of food irradiation. Our respondents are willing to pay a premium of about $0.77 for a pound of irradiated ground beef, which is higher than the cost to irradiate the product.
Le présent article porte sur l'estimation de la volonté de payer des consommateurs pour diminuer le risque de contracter une maladie d'origine alimentaire. L'étude a été réalisée en effectuant une expérience sur le terrain à l'aide de vrais produits alimentaires (à savoir du bœuf haché), d'argent réel et d'échange réel en situation de marché. Les répondants avaient reçu de l'information sur l'irradiation des aliments. Nous avons mis au point des modèles à une limite et à une limite et demie utilisant la méthode des choix dichotomiques. Nos résultats ont montré que les consommateurs étaient prêts à payer pour diminuer le risque de contracter une maladie d'origine alimentaire, une fois informés sur l'irradiation des aliments. Nos répondants étaient prêts à payer une prime d'environ 0,77$ la livre pour obtenir du bœuf haché irradié, soit une somme supplémentaire supérieure au coût de l'irradiation du produit.     

Su Una Estensione Bidimensionale del Teorema di Scomposizione di Peccati

Facendo ricorso all’introduzione di una opportuna condizione di sincronia fra due coppie di tassi (i, j), esterna, e (i*, j*), interna, si dimostra che condizione necessaria e sufficiente per la validità finanzíaria di una estensione hidimensionale del teorema di scomposizione di Peccati è che le due coppie (i, j) e (i*, j*) soddisfino tale proprietà di sincronia.

A two-dimensional extension of peccati’s decomposition theorem

Summary This paper keeps as starting poing the Peccati’s decomposition of the d.c.f. of an enterpreneural project seen as a present value of single-period results, recently given by the author in an unidimensional framework. The goal of the paper is twofold: the first is to provide a bidimensional extension of the decomposition in order to keep account of mixed projects, that is projects that according to any internal couple (i*, j*) reveal alternance of investment and respectively collection periods. A straightforward extension is given on the basis of a simple analogic argument. But a more careful evaluation of the problem suggests that if we require that the decomposition be meaningful from a financial point of view. things are no more simple either in one or in two dimensions. To solve the problem we introduce a proper synchrony condition: precisely, the pair of couples (i, j) and (i*, j*) are said to satisfy the synchrony condition if and only if the sequences of the signs of the partial balancesM _t (i, j) andM _t (i*, j*) are the same. After that we are able to show that, with reference to a couple (i, j) of external rates, a bidimensional decomposition centered on an internal couple (i*, j*) is meaningful if and only if the pair (i, j) and (i*, j*) satisfy the synchrony condition. Formally, the result comes as a nice byproduct of a rule on the factorization of particular bivariate polynomials recently given by Stucchi. In particular going back to a one-dimensional world, it turns out that for pure investment (Soper) projects the synchrony condition works as a condition of applicability of the Peccati’s decomposition.

The Effect of Perceived Value and Switching Barriers on Customer Price Tolerance in Industrial Energy Markets

Purpose: This article analyzes the effects of perceived value, satisfaction, and switching barriers on price tolerance. It also examines the moderating effect of switching barriers.

Methodology/Approach: Empirical research was conducted by collecting information from a sample of 326 major gas and electricity consumers in a newly liberalized industrial market with a high concentration of suppliers.

Findings: Switching barriers are the main antecedent to price tolerance. Price tolerance of industrial customers depends directly on switching barriers more than on satisfaction. The customer satisfaction construct is a necessary but not sufficient predictor of price tolerance. While satisfaction has an effect on price tolerance, the effect of perceived value on price tolerance is only indirect through satisfaction, even though it may produce positive direct effects when there are high switching barriers.

Originality/Value/Contribution: For the first time in a B2B framework, the moderating effects of switching barriers on the relationship between perceived value, satisfaction, and price tolerance have been analyzed.     

Does recession drive convergence in firms’ productivity? Evidence from Spanish manufacturing firms

This paper provides evidence on the effect of recessions and expansions on the productivity growth rate of productivity leaders and followers. We use data of a representative sample of the Spanish manufacturing sector for the period 1991 and 2005. These data allow us to estimate firm level productivity for a relatively long period of time and provide us with firm level perception of the business cycle. We find that productivity tends to converge in recessions because, in these periods, the productivity growth of followers is higher than the productivity growth of leaders. This fact is consistent with theoretical models of managerial incentives and competition. A recession can be seen as an exogenous increase in competition that reduces demand and poses a threat of liquidation. This threat is higher for followers and is high enough to create asymmetric incentives to become more productive. We test the robustness of our results to sample selection and different productivity measure.     

Food expenditures and household demographic composition in the US: a demand systems approach

Food expenditures and subsistence quantities of poverty status and non–poverty status US households are analysed within a Linear Expenditure System that postulates subsistence quantities to be linear combinations of demographic variables. Using the US Bureau of Labor Statistics' 1992 Consumer Expenditure Survey and Detailed Monthly Consumer Price Indices, this article obtains expenditure elasticities, own–price elasticities and subsistence quantities for each income group across nine broadly aggregated food commodity groups. Elasticity estimates and subsistence quantity estimates differ across income groups, supporting the premise that policies targeted at specific income groups should be based on the target group's elasticity estimates rather than average population elasticities. Parameter estimates are then used to simulate how subsistence quantities and own–price elasticities can be expected to vary according to the demographic composition of the household within a specific income group.     

The effect of innovation policy on SMEs’ employment and wages in Argentina

This article evaluates the effect of the Argentinean Support Program for Organizational Change on employment and wages. The program aimed at increasing small and medium-sized enterprises’ competitiveness by co-financing technical assistance to support process and product innovation activities. Although employment is not usually the main objective of these types of programs, they are always implemented assuming that they create—or at least do not destroy—employment opportunities. We use a unique data set with information for the population of firms in Argentina from 1996 to 2008 to test this important assumption. Using a combination of fixed effects and matching, we find that both process and product innovation support increased employment and wages, with a higher impact on employment. In addition, we find that product innovation support had a larger effect on wages than process innovation support.     

Consumers’ Preferences and Attitudes Toward Local Food Products

In recent years, consumers’ interest in local food has significantly increased. Several studies in the agricultural economics and marketing literature have analyzed mainly consumers’ preferences for local food products. In this study, we perform a consumer segmentation with regard to consumer behavior toward local food. We collected data from a survey conducted during summer 2010 in Naples, South Italy. Consumer segments were identified taking account of five aspects: (1) food consumption styles; (2) perception of local food; (3) purchasing motives; (4) perceived quality of local food; and (5) sociodemographic characteristics. They could be profiled as ethnocentric consumers, environmentalists, strict localists, and quality labeling oriented.     

Assessing Consumers’ Willingness to Pay for Different Units of Organic Milk: Evidence from Multiunit Auctions

Experimental auctions are normally conducted using single‐unit auctions. In this paper, we use the multiunit Vickrey auction to assess the determinants of consumers’ willingness to pay (WTP) for organic milk in a multiunit shopping scenario. We also analyze the effect of positive and negative information about organic farming on WTP. Our results suggest that consumers are willing to pay a premium for organic milk but that this WTP decreases with the number of units purchased. Results also suggest that health issues, high price of organic foods, taste, and lack of information on organic foods are factors that influence WTP for organic milk. The type of information provided also plays a relevant role. Specifically, we found that subjects’ WTP responds positively to positive information about organic farming and responds negatively to negative information. The provision of both positive and negative information does not affect WTP. Les enchères expérimentales sont en règle générale effectuées sous un cadre d’enchères de Vickrey à une seule unité. Dans le présent article, nous avons utilisé l’enchère de Vickrey à unités multiples pour évaluer les déterminants du consentement à payer (CAP) des consommateurs pour du lait biologique dans un contexte d’achats multiples. Nous avons également examiné les répercussions que l’information positive et négative à l’égard de l’agriculture biologique a sur le CAP. Nos résultats autorisent à penser que les consommateurs sont prêts à payer un prix plus élevé pour obtenir du lait biologique, mais que ce CAP diminue avec le nombre d’unités achetées. Nos résultats autorisent aussi à penser que les aspects liés à la santé, le prix élevé des aliments biologiques, le goût et le manque d’information sur ces aliments sont des facteurs qui influencent le CAP pour du lait biologique. Le type d’information joue également un rôle important. Nous avons observé que le CAP réagit favorablement à de l’information positive sur l’agriculture biologique et défavorablement à de l’information négative. La diffusion simultanée d’information positive et négative n’influence pas le CAP.     

The Adding-Up Test in an Incentivized Value Elicitation Mechanism: The Role of the Income Effect

In the context of testing the construct validity of stated preference studies, some researchers advocate the use of an “adding-up test” designed to gauge whether elicited values are sufficiently sensitive to a change in the scope (i.e. size) of a good. Crucial to the applicability of this test in practice, which relies on endowing a subsample of respondents with a good free of charge, is that the income effects due to endowment are negligible. In this study, we apply the adding-up test in an experimental value elicitation format to examine the potential effect of endowment as part of the test design on the adding-up property of elicited values. The results show that the adding-up property can be affected by free provision of part of the bundle.
