Bounds on the estimation error in the chain ladder method

Buchwalder et al. (2006) have illustrated that there are different approaches for the derivation of an estimate for the parameter estimation error in the distribution-free chain ladder reserving method. In this paper, we demonstrate that these approaches provide estimates that are close to each other for typical parameters. This is carried out by proving upper and lower bounds.     

Innovation and Development: The Evidence From Innovation Surveys

In this article we investigate the existing evidence on innovation produced by innovation surveys in developing and emerging countries in Europe, Asia, Africa, and Latin America. We review the relevant literature, discuss methodological issues, and analyze the results for the countries with the most comparable surveys, considering the well-established findings of innovation surveys for Europe as a benchmark. From the evidence we considered, regional patterns are identified and some stylized facts on innovation and development are proposed, pointing out the specificity of innovation processes in economies engaged in industrialization and catching up.     

Should Variable Cost Aid to Attract Foreign Direct Investment be Banned? A European Perspective

The purpose of this paper is to analyze the European Commission’s approach to state aid to attract foreign direct investment (FDI) in a competition policy framework. The Commission considers variable cost aid (VCA) to be more distortive than start-up or fixed cost aid (FCA). This paper addresses that issue and checks whether allowing FCA while banning VCA is an optimal strategy for a supranational Competition Authority maximizing welfare. The model shows that a domestic government maximizing welfare always prefers VCA to FCA if both the incumbent and the entrant are foreign firms and if granting VCA does not cause the incumbent firm to exit the market. The model shows that banning VCA may lead to sub-optimal equilibria where welfare is not maximized.     

Boundary spanner turnover in professional services: Exploring the outcomes of client retention strategies

Abstract

Studies suggest that the termination of the interpersonal relationship between boundary spanners at buyer and seller firms can have a damaging effect on the inter organisational relationship. Few studies have addressed this issue in detail, but those that do, advise supplier firms to implement strategies such as service teams and boundary spanner rotation to lessen the negative effects of boundary spanner turnover. By creating multiple bonds between the two firms, dispersing client-specific knowledge widely throughout the supplier firm, and preventing the development of a close bond between buyer and seller boundary spanners, individual interpersonal relationships become less important. However, a review of relationship literature on trust, commitment, social bonds, and knowledge suggests the potential for negative outcomes from the implementation of the strategies. Using case studies and one-to-one interviews with design buyers and their agencies, this paper explores the outcomes of the two strategies, and the contexts in which these outcomes occur. Adopting a critical realist approach, findings are presented in the form of context–mechanism–outcome models. Agency size, agency culture, client experience, and boundary-spanner autonomy are amongst the contexts that influence the outcome of strategy implementation.     

Sources of Firm Performance Differences in the US Food Economy

Researchers in economics and strategy have long been interested in understanding the determinants of firm performance. We apply the relatively novel approach of hierarchical linear modelling (HLM) to a large panel of food economy firms to shed new light on the long‐standing debate about the relative importance of industry, corporate parent and business unit effects on firm profits. Our results suggest that business unit and corporate effects are more relevant than industry effects in explaining firm performance differences in the food economy. In addition, we also explore the effect of specific strategic factors on performance within each level of analysis. In particular, we find that business‐segment size, industry barriers to entry, corporate diversification, R&D intensity, capital intensity and resource availability are significant predictor variables that explain firm performance differences. Given the relatively important role of corporate effects and the positive influence of corporate strategic variables on business unit performance, our findings suggest that the environment provided by corporate parents significantly affects business unit profitability. In other words, corporate strategy does matter and thus should continue to draw attention from scholars interested in explaining profitability in the food economy.     

When Consumers and Products Come From the Same Place: Preferences and WTP for Geographical Indication Differ Across Regional Identity Groups

ABSTRACT

This article contributes to the existing literature on geographical indications by observing consumers’ stated preference for extra-virgin olive oil in two groups differing in their regional identity. In particular, consumers from two groups were asked to rank products in a contingent ranking survey. One group (“insiders,” Sicilian consumers) shared origin with a good product (Sicilian oil); the other group (“outsiders,” Rome and Milan) presented “no association” consumer-product. Results indicate that insiders are willing to pay more for goods originating from the region they identify with compared with a region associated with outsiders. Identity seems to give a bias by which a local product is not necessarily perceived as superior in absolute terms, but in relative terms: outside products are never considered better than inside options but are either inferior or equal in perceived value.     

Production and financial policies under asymmetric information

We propose an extension of the standard general equilibrium model with production and incomplete markets to situations in which (i) private investors have limited information on the returns of specific assets, (ii) managers of firms have limited information on the preferences of individual shareholders. The extension is obtained by the assumption that firms are not traded directly but grouped into ‘sectorial’ funds. In our model the financial policy of the firm is not irrelevant. We establish the existence of equilibria and discuss the nature of the inefficiencies introduced by the presence of asymmetric information. We also illustrate the properties of the model in three simple examples. We would like to thank Alberto Bisin, Armando Dominioni, Piero Gottardi, Tito Pietra, Paolo Siconolfi, and an anonymous referee for useful suggestions and comments.     

Testing assumptions underlying economic research on transgenic food crops for Third World farmers: Evidence from Cuba, Guatemala and Mexico

Transgenic crop varieties (TGVs) are being promoted as essential for improving small-scale Third World (SSTW) agriculture. Most economic research on this topic makes critical, untested assumptions, including that farmers will choose TGVs over other varieties because TGVs are economically optimal and because farmers are risk neutral profit maximizers. We tested these assumptions using data from a survey of 334 farmers in 6 communities in Cuba, Guatemala and Mexico in which farmers ranked 4 real and hypothetical maize varieties for eating and sowing. Our results did not support these assumptions. Most farmers preferred farmer varieties for sowing and especially for eating, avoiding TGVs, a preference associated with being risk averse and with non-monetary preferences. Farmers more integrated into modern agriculture were more likely to choose TGVs. These results suggest that farmers most in need of support and most important for conserving genetic diversity are least favorable toward TGVs, and that alternative ways of improving SSTW agriculture should receive more attention.     

Influence of institutional environment on entrepreneurial intention: a comparative study of two countries university students

Institutional environment influences the perceptions of desirability and feasibility, society’s social and cultural environment, such as beliefs, values and attitudes, conditions behaviour and decisions made by individuals. This research evaluates the influence of institutional environment on entrepreneurial intention using a comparative analysis of different attitudes among university students in two countries: Portugal and Spain. In particular, this study aims to examine the perceptions of desirability, feasibility and intention toward the creation of one’s own business and how that variables influence the entrepreneurial intention as compared these two different institutional contexts. Results revealed difference among attitudes toward entrepreneurship in both countries. With respect to the perception of feasibility, the majority of students in Extremadura (Spain) consider that it is easier to create a business in nowadays than it was several decades ago. However, from the students of Beira Interior (Portugal) consider that it is more difficult. Furthermore, in Extremadura, the entrepreneurial intention is higher than in Beira Interior.
