| Abstract: | We analyze under what condiitons credit markets are efficient in providing loans to entrepreneurs who can start a new project after previous failure. An entrepreneur of uncertain talent chooses the riskiness of her project. If banks cannot perfectly observe the risk of previous projects, two equilibria may coexist: (1) an inefficient equilibrium in which the entrepreneur undertakes a low-risk project and has no access to finance after failure; and (2) a more efficient equilibrium in which the entrepreneur undertakes high-risk projects and gets financed even after an endogenously determined number of failures. |

| Abstract: | When is the rigorous impact evaluation of development projects a luxury, and when a necessity? This Paper studies one high-profile case: the Millennium Villages Project (MVP), an experimental and intensive package intervention to spark sustained local economic development in rural Africa. it illustrates the benefits of rigorous impact evaluation in this setting by showing that estimates of the project's effects depend heavily on the evaluation method. Comparing trends at the MVP intervention sites in Kenya, Ghana, and Nigeria to trends in the surrounding areas yields much more modest estimates of the project's effects than the before-versus-after comparisons published thus far by the MVP. Neither approach constitutes a rigorous impact evaluation of the MVP, which is impossible to perform due to weaknesses in the evaluation design of the project's initial phase. These weaknesses include the subjective choice of intervention sites, the subjective choice of comparison sites, the lack of baseline data on comparison sites, the small sample size, and the short time horizon. The authors describe how the next wave of the intervention could be designed to allow proper evaluation of the MVP's impact at little additional cost. |

| Abstract: | Cooperation and collaboration between companies represents a key issue within the conceptual framework developed by the IMP Group. However, little attention has been paid to a phenomenon which can result from such collaboration, i.e. collective action. This involves cooperative activities undertaken by a significant number of actors sharing a common aim. This research uses the concept of issue-based net to open new avenues to understand collective action in the context of innovation activities, specifically by analyzing a case study of an innovation-based net in the automotive industry. Two main objectives are addressed in this study: Related to this discussion of different development paths of collective actors, the case study analysis focuses on how issue-based nets emerge and evolve in situations of innovation, specifically, what kind of structure and process issues characterize a heterarchization development path. Furthermore, the analysis addressed how issue-based nets change the positioning of individual member firms, a well as that of the collective actor within the overall network. |

| Abstract: | "The current research report deals with intensified and extended intensified vocation- al guidance measures and the possibilities of evaluating them. (Extended) intensified vocational guidance is offered in many places to help young people in their transition to training. The analysis of a survey within the Federal Employment Agency showed that these measures are extremely heterogeneous and pursue very differing goals. The report presents some of these measures and the approaches used in accompanying research. It becomes apparent that, while these studies are valuable as practical reports, they do not meet the demands of scientific evaluation. For this reason, current evaluation projects are then outlined and a concept for further evaluations that meet scientific requirements developed; furthermore concepts for the evaluation of individual types of measures that have been implemented in North Rhine-Westphalia and Thuringia as of summer 2010 are presented. The report concludes by making the suggestion that less individual measures or types of measures are evaluated in future but rather that one concentrates on the offers that are available in individual schools, communities or regions and how these interact."

| Abstract: | We introduce von Neumann-Morgenstern solution concepts in market models involving the choice of a public project. We show that vN-M stable sets, suitably defined in connection to public goods provision, are consistent with results from bargaining via cartels. We find as necessary the assumption that stability is defined with respect to blocking procedures in which coalitions do not necessarily pay for the whole realization of the project, but only for a fraction of it and that costs are distributed uniformly in each corner of the market. Under this assumption, we obtain large games solutions by the finite ones via embedding procedures. Going further in the investigation of stable solutions, we define stable sets following the “sophisticated” approach suggested by Harsanyi (see [15] and [17]), proving that a sigma-sophisticated stable set corresponds to the solution in the associated payoff space. |
