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.

In the area of dynamic economics, David Cass’s work has spawned a number of important lines of research, including the study of dynamic general equilibrium theory, the concept of sunspot equilibria, and general equilibrium theory when markets are incomplete. Based on these contributions, this volume contains new developments in the field, written by Cass's students and co-authors.

News Professor Cheng-Few Lee ranks #1 based on his publications in the 26 core finance journals, and #163 based on publications in the 7 leading finance journals (Source: Most Prolific Authors in the Finance Literature: 1959-2008 by Jean L Heck and Philip L Cooley (Saint Joseph's University and Trinity University). Market microstructure is the study of how markets operate and how transaction dynamics can affect security price formation and behavior. The impact of microstructure on all areas of finance has been increasingly apparent. Empirical microstructure has opened the door for improved transaction cost measurement, volatility dynamics and even asymmetric information measures, among others. Thus, this field is an important building block towards understanding today's financial markets. One of the pioneers in the field of market microstructure is David K Whitcomb, who retired from Rutgers University in 1999 after 25 years of service. David generously funded the David K Whitcomb Center for Research in Financial Services, located at Rutgers University. The Center organized a conference at Rutgers in his honor. This conference showcased papers and research conducted by the leading luminaries in the field of microstructure and drew a broad and illustrious audience of academicians, practitioners and former students, all who came to pay tribute to David K Whitcomb. Most of the papers in this volume were presented at that conference and the contributions to this volume are a lasting bookmark in microstructure. The coverage of topics on this volume is broad, ranging from the theoretical to empirical, and covering various issues from market architecture to liquidity and volatility.
