Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

A mechanism is a mathematical structure that models institutions through which economic activity is guided and coordinated. There are many such institutions; markets are the most familiar ones. Lawmakers, administrators and officers of private companies create institutions in order to achieve desired goals. They seek to do so in ways that economize on the resources needed to operate the institutions, and that provide incentives that induce the required behaviors. This book presents systematic procedures for designing mechanisms that achieve specified performance, and economize on the resources required to operate the mechanism. The systematic design procedures are algorithms for designing informationally efficient mechanisms. Most of the book deals with these procedures of design. When there are finitely many environments to be dealt with, and there is a Nash-implementing mechanism, our algorithms can be used to make that mechanism into an informationally efficient one. Informationally efficient dominant strategy implementation is also studied.

Debunking the current model of international aid promoted by both Hollywood celebrities and policy makers, Moyo offers a bold new road map for financing development of the world's poorest countries.

First published in 1987, Incentives and Economic Systems is a selection of papers presented at the Eighth Arne Ryde Symposium at Frostavallen, Sweden on how institutions attempt to guide individual behaviour by manipulating the social and economic incentive system. These economic and social aspects of incentives determine ‘rational’ and ‘irrational’ behaviour by individuals and organizations across various economic systems. The essays in the volume deal with various aspects of the incentive problems and the various manifestations of such problems, along with moral and ethical issues. The essays will be an enlightening read for students of economics, policymaking and international politics.
