New models for measuring the R&D performance and identifying the productivity of public research institutes

Research evaluation of public institutes is important for measuring the performance of the science sector and improving the cost effectiveness and efficiency of public resource allocation. The purpose of this article is to construct a means of classifying publicly-funded R&D institutions and their performance (high or low). The main findings are two research performance functions, created using discriminant analysis with direct and Wilks methods, which have been successfully applied to 200 public research institutes belonging to the Italian National Research Council. The large number of indicators used within the models creates a macro index that produce, as output, the research performance score. The data analysed is from the 2001 period. The results show that 22.5% of public labs fall into the 'high performance institute' bracket and that they have a site larger than 'low performance institutes'. The models are useful tools for decision making within the research bodies and for reducing X-inefficiency.     

Managing commitments and flexibility by real options

In the past, transaction cost economics (TCE) literature has largely stressed the benefits of contractual commitments in relationships. TCE traditionally recommends safeguarding specific assets against holdup, thus reducing behavioral uncertainty. In contrast, the reverse side of the coin has been disregarded for a long time. Firms may lose some of their flexibility and thus the opportunity to benefit from future emerging business activities due to prior contractual commitments. Flexibility becomes especially important in dynamic environments where there is rapid technological change. To manage the emergent trade-off between contractual commitments and flexibility in dynamic markets, the authors propose a real options approach. The value of a firm's flexibility to switch to a new trading partner is represented by a real switching option. It can be shown how contractual commitments directly affect the value of the switching option. To clarify, the authors numerically analyze the respective trade-off and derive implications for an optimal choice of contractual commitments.     

Business ethics in Italy: The state of the art

Up until now, the work which has been done in Italy might be considered of a preparatory nature. In 1985 and in 1986, the association of Catholic businessmen produced two documents on the ethical implications of economic activity. But in those years, the world of big business, had not yet realised how central the argument was becoming.The first significant signs of interest for business ethics appeared in 1987. In June, 1988, the first Italian National Conference on Business Ethics took place in Milan. The main outcome of that conference has been the constitution of the Italian Chapter of the European Network. In 1988, I founded the first issue of the journal entitled Etica degli-Affari. Promotional efforts have developped along two lines. The first regards programs of executive training and, eventually, consulting. In the second place, efforts are being made to elaborate and introduce codes of ethics in Italian corporations. There are, however, some very fundamental difficulties involved in the promotion of Business Ethics in Italy. The first problem is the fact that Italy is a country with a low ethical temperature. We don't have a strong sense of national identity, nor do we have a strong sense of the state. The second difficulty has to do with the business environment — the Italian business community itself. As a self-conscious, self-aware nucleus of a sector of society, the Italian business community is a very recent, and rather minoritarian social phenomenon.I personally feel that a certain protagonism on the part of prominent business leaders who are quite sensitive to the theme of ethics would prove to be very influential and greatly accelerate the process.Mario Unnia is managing director of Prospecta, a research firm, Milan, Italy. He has lectured and published extensively in the fields of Business and Public Policy, Corporate Culture and Labour Relations. He has founded and is chairman of the Italian Business Ethics Network. He is editor of Etica degli Affari.     

TRANSITIONS OUT OF UNEMPLOYMENT: THE ROLE OF SOCIAL NETWORKS' TOPOLOGY AND FIRMS' RECRUITMENT STRATEGIES

In this paper we study the effects of job contact networks on out‐of‐unemployment transitions. We find that social connections produce sizable increases in upward mobility from unemployment and, caeteris paribus, symmetric network topologies perform better than asymmetric ones. Furthermore, in scale‐free networks the probability of transitions out of unemployment increases in the exponent of the power‐law degree distribution, but its value is much lower than the one attainable in Poisson random networks. In addition, and most interestingly, these results strongly depends on the different hypotheses on the firms' recruitment strategy.     

Accounting Year Effects Modeling in the Stochastic Chain Ladder Reserving Method

Abstract

In almost all stochastic claims reserving models one assumes that accident years are independent. In practice this assumption is violated most of the time. Typical examples are claims inflation and accounting year effects that influence all accident years simultaneously. We study a Bayesian chain ladder model that allows for accounting (calendar) year effects modeling. A case study of a general liability dataset shows that such accounting year effects contribute substantially to the prediction uncertainty and therefore need a careful treatment within a risk management and solvency framework.     

Environment-Related Litigation in Rio de Janeiro: Shaping Frames for a New Social Problem

This article aims to contribute to an understanding of how the environment is constituted as a social problem in Rio de Janeiro. In order to account for the local contours of this global phenomenon, it considers contextual aspects that frame environmental conflicts in Rio de Janeiro and examines certain relevant cultural resources. An analysis of the accounts of two actors involved in environmental litigation serves as the point of departure for an inventory of the versions of environment available for public debate. Le but de cet article est d’aider à mieux comprendre comment l’environnement en vient àêtre construit comme un problème social à Rio de Janeiro. Afin d’expliquer les profils locaux de ce phénomène global, cet article considère les aspects contextuels qui structurent les conflits de l’environnement à Rio de Janeiro et examine certaines ressources culturelles pertinentes. L’analyse des compte-rendus de deux participants impliqués dans les litiges de l’environnement sert de point de départ à un inventaire des différentes versions de l’environnement utilisées pour les débats publics.     

R&D-Related Capabilities as Determinants of Export Performance

Empirical evidence from a sample of independent and privately held specialized suppliers all of which are engaged in formal R&D activities shows that specific R&D-related capabilities are determinants of different types of export performance. The major contribution of this paper is to take into account traditional measures of R&D activities as well as a broad range of R&D-related capabilities to further our understanding of the export behavior of SMEs in terms of volume and final destination of sales. Results suggest that the set of determinants varies with firms' internationalization process. In particular, determinants associated with the more global firms are significantly at odds with our traditional conception of a small firm and appear to be more aligned with the behavior generally found in proactive large exporters.     

RANDOM WALK TESTS FOR LATIN AMERICAN EQUITY INDEXES AND INDIVIDUAL FIRMS

In this study we re-examine the presence of random walk in stock prices in Brazil and Mexico. We employ variance ratio tests on weekly stock returns for indexes as well as individual firms. The results reveal mean aversion in Mexico at both the index level and the firm level. In contrast, the Brazil indexes show a greater tendency toward random walk; however, the results for the individual firms suggest mean reversion. The results cannot be attributed to a firm size effect. Evidence is presented in favor of a greater degree of nonsynchronous trading for Brazilian securities than for Mexican securities.     

Wealth and Income Inequality in Europe

While it has long been apparent that global levels of wealth and income inequality have been steadily increasing since the 1970s, the issue received scant attention in Europe until the recent fi nancial crisis and the resulting Great Recession illuminated for the general public just how great the chasm between the very rich and everybody else had grown. This realisation was coupled with an increased focus on inequality among economists and other academics, leading to a fresh drive for policy ideas to remedy the alarming trend. This Forum comprises a diverse range of viewpoints on the recent history and dynamics of inequality within Europe, each striving to defi ne the root causes in the various countries being examined. The defi nition of these causes, of course, can inform the direction of policies aimed at alleviating the growing inequality in many European countries and thereby curtail one of the major political and social issues of our time.
