EXPLAINING PRIVATE PROVISION OF PUBLIC GOODS BY CONDITIONAL COOPERATION: AN INDIRECT EVOLUTIONARY APPROACH

We adopt an indirect evolutionary approach to investigate whether and when conditional cooperation can explain the voluntary contribution phenomenon often observed in public goods experiments and in real life. Formally, conditional cooperation is captured by a guilt parameter describing how much an individual feels guilty about contributing less than the average. We find that the evolutionary stability of conditional cooperation depends on what is known about the (individual) guilt parameter of other group members.     

Product market competition and access to credit

In this paper, we unveil a disregarded benefit of product market competition for firms. We introduce the probability of bankruptcy in a simple model where firms compete à la Cournot and apply for collateralized bank loans to undertake productive investments. We show that the number of competitors and the existence of outsiders willing to acquire the productive assets of distressed incumbents affect the equilibrium share of investment financed by bank credit. Using a sample of Italian manufacturing firms, mostly small- and medium-sized enterprises (SMEs), we found evidence showing that the degree of product market competition is positively correlated with the share of investment financed by bank credit only when outsiders are absent.     

The Impact of Payoff Interdependence on Trust and Trustworthiness

Abstract. In one‐shot investment games where each player's payoff is a convex combination of own and other's profit, we measure trust by the amount given to the trustee and trustworthiness by the amount returned to the trustor by the trustee. Does the degree of payoff interdependence increase both trust and trustworthiness or one but not the other or neither of them? According to our experimental data, trust remains unaffected by the extent of interdependence whereas trustworthiness reacts positively to it.     

An Application of the English Clock Market Mechanism to Public Goods Games

This paper reports an experimental study of the public goods game in which contributions are not submitted all at once but incrementally as coordinated in real time by a clock. Individuals press a button as soon as the clock equals their willingness to contribute. By providing information about the point at which subjects stop further contributions we find evidence for conditionally cooperative behaviour: A subject's decision to stop contributing induces an immediate reaction of the other group members.

Branching and competition in the European banking industry

In this study branching costs and competitiveness of European banks are measured by fitting a monopolistic competition model to a representative sample drawn from nine EEC banking industries in the period from 1990 to 1996. In the theoretical model, banks decide strategically the size of their branching network anticipating the degree of competition faced on interest rates. From the structural equations of the model an econometric test is derived in order to measure branching costs and degree of competition in banking services. The empirical analysis captures their changing over time together with the impact of various European directives aiming at deregulating the banking industry. Furthermore the study shows persistence of segmentation acoss EEC banking industries.     

A test of the impact of mergers on bank competition

We propose a new test to evaluate the impact of horizontal mergers on competition in the banking industry. The test is designed to be applied ex ante to potential mergers while being parsimonious in terms of data, as it only uses information on branches in local markets. The test is a counterfactual exercise based on a two‐stage model where banks compete in branching and interest rates and requires comparing the estimated degree of competition in the status quo, where branching networks by banks are those actually observed, with a counterfactual scenario, where the branching network of the new entity is the sum of the branches of the banks involved in the horizontal merger. The statistical difference between the two estimated measures of competition quantifies the impact of the merger. We apply our test to French and Italian mergers.     

Investigating the Influence of Technology Inflows on Technology Outflows in Open Innovation Processes: A Longitudinal Analysis

The open innovation (OI) paradigm emphasizes the importance of integrating inbound and outbound flows of technology to increase a firm's innovation performance. While the synergies between technology inflows and outflows have been discussed in conceptual OI articles, the majority of empirical studies have typically focused on either the inward or the outward dimension of OI. According to recent reviews of OI literature, there is a need for further research that takes an integrated perspective on this topic and studies the combination of the inbound and outbound dimensions of OI. This paper follows these calls by focusing on technology licensing as the main contractual form for OI, and by investigating the relationship between technology in‐licensing and out‐licensing activities at the firm level of analysis. In particular, this paper argues that technology in‐licensing positively influences the volume of technology out‐licensing through two mechanisms. The first—resource‐based—occurs because in‐licensing investments expand and enrich the firm's technology base, thus increasing its value and, as a result, creating more opportunities for out‐licensing. The second—capabilities‐based—occurs because, due to commonalities between technology in‐licensing and out‐licensing in terms of performed tasks and required skills, repeated execution of in‐licensing transactions contributes to the development of higher out‐licensing capabilities and, as a result, increase out‐licensing volume. These arguments are tested using a panel dataset of 837 Spanish manufacturing firms over the period 1998–2007. Consistent with the predictions, the empirical analysis shows that higher investments in in‐licensing and more extensive in‐licensing experience lead to superior volumes of technology out‐licensing. These results contribute to research on OI and licensing, by empirically showing the existence of positive interactions between technology inflows and outflows and of synergies in the development of absorptive and desorptive capacities.     

Collective Choices Under Ambiguity

We investigate experimentally whether collective choice environments matter for individual attitudes to ambiguity. In a simple two-urn Ellsberg experiment, one urn offers a 45 % chance of winning a fixed monetary prize while the other offers an ambiguous chance. Participants choose either individually or in groups of three. Group decision rules vary in the level of individual responsibility for the others’ payoffs: the collective choice is taken by majority, randomly delegated to two group members, or randomly delegated to a single group member. Although most participants display consistent ambiguity attitudes across their decisions, taking responsibility for the others tends to foster ambiguity aversion.
