Social capital and the Creation of Knowledge

Abstract: This paper examines the relationship between the social capital and knowledge creation in research, mostly in the context of universities. The analysis is developed considering all of the following critical aspects of social capital: direct ties, strengths of direct ties, density, structural holes, centrality, and external-internal index in terms of fields of knowledge. Two important results arise from this research. First, the overall results suggest that, when controlling for other network variables and individual heterogeneity, the effects of the structural holes variable disappear. This result stands in contrast to the established idea that structural holes is the most important variable to represent social capital and, therefore, is seen as contributing to superior performance. Second, the results show that with this strong set of controls, what matters in social capital is having many direct ties, being in a central position, having partners from different areas of knowledge, and being part of a non dense network.

Resonance zones and lobe volumes for exact volume-preserving maps

Abstract: We study exact, volume-preserving diffeomorphisms that have heteroclinic connections between a pair of normally hyperbolic invariant manifolds. We develop a general theory of lobes, showing that the lobe volume is given by an integral of a generating form over the primary intersection, a subset of the heteroclinic orbits. Our definition reproduces the classical action formula in the planar, twist map case. For perturbations from a heteroclinic connection, the lobe volume is shown to reduce, to lowest order, to a suitable integral of a Melnikov function.

The Informational Role of Voluntary Certification: Evidence from the Mexican Clean Industry Program †

Abstract: While it has long been recognized that voluntary certification programs designed to reduce emissions can importantly complement command and control regulation (e.g., Ayres and Braithwaite 1992), an absence of empirically validated regulatory models has hampered the design and implementation of such programs. Instead, much of the policy debate has focused on certification programs as an alternative to other forms of environmental controls and on whether voluntary programs result in reduced environmental impact among participatory firms. Particular skepticism has been directed toward the use of voluntary programs in developing countries due to low levels of regulatory capacity, pressure on the part of firms to compete in a global economy, and low levels of household income (Blackman 2009; Anton, Deltas, and Khanna 2004). In this paper we argue that voluntary certification can play an important role in the revelation of information about firm costs of compliance that can, in turn, increase the efficacy of command and control regulation. In particular, we

Optimal combinatorial mechanism design

Abstract: We consider an optimal mechanism design problem with several heterogenous objects and interdependent values. We characterize ex post incentives using an appropriate monotonicity condition and reformulate the problem in such a way that the choice of an allocation rule can be separated from the choice of the payment rule. Central to the analysis is the formulation of a regularity condition, which gives a recipe for the optimal mechanism. If the problem is regular, then an optimal mechanism can be obtained by solving a combinatorial allocation problem in which objects are allocated in a way to maximize the sum of virtual valuations. We identify conditions that imply regularity using the techniques of supermodular optimization.
