Curvature and transport inequalities for Markov chains in discrete spaces

Abstract: We study various transport-information inequalities under three different notions of Ricci curvature in the discrete setting: the curvature-dimension condition of Bakry and Emery, the exponential curvature-dimension condition of Bauer \textit{et al.} and the coarse Ricci curvature of Ollivier. We prove that under a curvature-dimension condition or coarse Ricci curvature condition, an $L_1$ transport-information inequality holds; while under an exponential curvature-dimension condition, some weak-transport information inequalities hold. As an application, we establish a Bonnet-Meyer's theorem under the curvature-dimension condition CD$(\kappa,\infty)$ of Bakry and Emery.

Audience effects and other-regarding preferences against corruption: Experimental evidence

Abstract: We report results from an experiment in which two firms compete for a public project by submitting offers of quality and bribery to a public official. We study the impact of audience effects (transparency) and other regarding preferences (accountability) on corruption by introducing a citizen who either observes, or is affected by the transactions, or both. The results suggest that transparency and accountability lead, independently, to lower bribe placement and acceptance. However, the conjoined effect does not promote prosocial behaviour further, indicating potential ceiling effects.
