New Tools to Foster Corporate Socially Responsible Behavior

According to the Green Paper presented by the European Commission in July 2001, corporate social responsibility (CSR) is “a concept whereby companies integrate social and environmental concerns in their business operations and in their interaction with their stakeholders on a voluntary basis” (Commission of the European Communities, 2001b, p. 6). On this basis, in 2002, the Italian Government, and especially the Italian Ministry of Welfare, launched an initiative called CSR-SC (social commitment) in order to foster the proactive social role of Italian enterprises, with great attention on SME involvement. The technical partner of the Italian Ministry of Welfare for this initiative is Bocconi University. The goal of this contribution is to present the main results of CSR–SC research project developed by Bocconi University. The paper provides a detailed picture of the general scheme designed to carry out the research project and a review of the different methodologies used to support the solutions proposed.     

Purchasing management in the luxury industry: organization and practices

Traditional supply chain models were developed mainly for non-luxury companies and find very little correspondence in the field of luxury, which is considered here as a business super-area including heterogeneous enterprises, belonging to different sectors, which have in common customers characterized by the “need for luxury”. The objective of this paper is to investigate, through a multiple case-study research, peculiar purchasing and supply management practices put in place by luxury firms and to provide a classification of the most recurring approaches. Relevant dimensions (i.e. product complexity and sale volume) to classify luxury firms practices have been used: as a result, four groups of companies have been identified and their purchasing practices described.     

On the Ramsey equilibrium with heterogeneous consumers and endogenous labor supply

In this paper, we address the stability issue, stressing the role of labor supply, in a Ramsey model with heterogeneous households subject to borrowing constraints. Making labor supply endogenous leads us to prove the existence of two kinds of steady state: the one where everybody supplies labor, the other where only the most patient agent refrains from working. Going beyond models with inelastic labor supply, we show how preferences of impatient agents affect the saddle-path stability of each type of steady state and the occurrence of endogenous cycles. When their elasticity of intertemporal substitution in consumption exceeds one, instability and cycles are less likely, requiring lower degrees of capital-labor substitution. Conversely, elasticity values below one promote the emergence of fluctuations. We end the paper by showing the existence of the intertemporal equilibrium under market incompleteness, using a local approach based on the first-order conditions.     

Economic integration,industrial structure,and catch-up growth: Firm-level evidence from Poland

We examine if and how deeper economic integration with high-income nations impacts industrial performance. We exploit Poland's accession to the EU in 2004 as a source of variation in the degree of market integration with Germany. Using data on Polish manufacturing firms in the period 1995–2013, we find that EU accession was followed by significant within-firm growth in output and productivity, notably in industries in which Germany was more specialized at the moment of accession. Increased flows of German investment to these sectors played an important role in shaping these effects.     

Preemption contests between groups

We consider a preemption game between competing groups; firms lobbying individually for their groups' interests provide an empirical example. Among symmetric groups, the first firm to take action bears an (unobserved) cost and wins the prize on behalf of its group. In equilibrium, the firm with the lowest cost takes action, but with delay. More competition and a smaller ratio of costs to benefits reduce delay. Firms in larger groups wait longer, but group action can occur earlier, as the probability of a low-cost firm is higher. Asymmetries in group size or strength of externalities also matter.     

Optimal design of experiments to identify latent behavioral types

Bayesian optimal experiments that maximize the information gained from collected data are critical to efficiently identify behavioral models. We extend a seminal method for designing Bayesian optimal experiments by introducing two computational improvements that make the procedure tractable: (1) a search algorithm from artificial intelligence that efficiently explores the space of possible design parameters, and (2) a sampling procedure which evaluates each design parameter combination more efficiently. We apply our procedure to a game of imperfect information to evaluate and quantify the computational improvements. We then collect data across five different experimental designs to compare the ability of the optimal experimental design to discriminate among competing behavioral models against the experimental designs chosen by a “wisdom of experts” prediction experiment. We find that data from the experiment suggested by the optimal design approach requires significantly less data to distinguish behavioral models (i.e., test hypotheses) than data from the experiment suggested by experts. Substantively, we find that reinforcement learning best explains human decision-making in the imperfect information game and that behavior is not adequately described by the Bayesian Nash equilibrium. Our procedure is general and computationally efficient and can be applied to dynamically optimize online experiments.

     

Supply Determinants of Mining Companies: Evidence for Gold and other Minerals in South Africa

Supply determinants of mining companies have been identified in several factors, with no consensus on their relative importance. These factors, which include mineral commodity prices, the institutional framework, geological characteristics, the scale of mine operations, and specific features of the controlling holdings, can influence the objectives of the mines, and their ability to achieve these objectives. Following a brief overview of alternative literature hypotheses concerned with mineral supply determinants, statistical and econometric analyses are applied to partly pooled cross-mine data over the period 1984–95, for gold and other major export minerals in South Africa. — Des déterminants de l’offre des sociétés minières ont été identifiés dans différents facteurs sans qu’un consensus se dégage quant à leur importance relative. Ces facteurs, au nombre desquels figurent les prix des produits minéraux, le cadre institutionnel, les caractéristiques géographiques, la taille de l’exploitation minière et les caractéristiques de la société de holding majoritaire, peuvent influer sur les objectifs des mines et sur leur aptitude à atteindre ces objectifs. Après une brève revue des hypothèses sous-tendant diverses théories relatives aux déterminants de l’offre des produits minéraux, une analyse statistique et économétrique est effectuée à partir de données partiellement communes, portant sur la période 1984–95, concernant l’or et d’autres importants produits minéraux d’exportation en Afrique du Sud.     

An organizational culture for all seasons? How cultural type dominance and strength influence different performance goals

Organizational culture might influence results, especially in public healthcare organizations characterized by strong professional control. This study investigates whether a specific culture type is most effective in fostering performances. We assess organizational culture through Competing Values Framework and use multivariate regression analysis to test the relationship between dominant culture and competitiveness and financial results. Based on 529 responses from senior managers of 59 organizations, we found that dominant rational and hierarchical culture types are associated, respectively, with higher competitiveness and better financial results. Enhancing a specific performance dimension might require cultural changes aimed to align values with targeted results.
