|May 2012||Industrial Policy and Competition|
with Philippe Aghion, Luosha Du, Ann Harrison, Patrick Legros: w18048
Using a comprehensive dataset of all medium and large enterprises in China between 1998 and 2007, we show that industrial policies allocated to competitive sectors or that foster competition in a sector increase productivity growth. We measure competition using the Lerner Index and include as industrial policies subsidies, tax holidays, loans, and tariffs. Measures to foster competition include policies that are more dispersed across firms in a sector or measures that encourage younger and more productive enterprises.

|April 2009||The Governance and Performance of Research Universities: Evidence from Europe and the U.S.|
with Philippe Aghion, Caroline M. Hoxby, Andreu Mas-Colell, André Sapir: w14851
We investigate how university governance affects research output, measured by patenting and international university research rankings. For both European and U.S. universities, we generate several measures of autonomy, governance, and competition for research funding. We show that university autonomy and competition are positively correlated with university output, both among European countries and among U.S. public universities. We then identity a (political) source of exogenous shocks to funding of U.S. universities. We demonstrate that, when a state's universities receive a positive funding shock, they produce more patents if they are more autonomous and face more competition from private research universities. Finally, we show that during periods when merit-based competitions for fed...

|March 2009||Of Mice and Academics: Examining the Effect of Openness on Innovation|
with Fiona Murray, Philippe Aghion, Julian Kolev, Scott Stern: w14819
Scientific freedom and openness are hallmarks of academia: relative to their counterparts in industry, academics maintain discretion over their research agenda and allow others to build on their discoveries. This paper examines the relationship between openness and freedom, building on recent models emphasizing that, from an economic perspective, freedom is the granting of control rights to researchers. Within this framework, openness of upstream research does not simply encourage higher levels of downstream exploitation. It also raises the incentives for additional upstream research by encouraging the establishment of entirely new research directions. In other words, within academia, restrictions on scientific openness (such as those created by formal intellectual property (IP)) may limit...

|August 2005||Academic Freedom, Private-Sector Focus, and the Process of Innovation|
with Philippe Aghion, Jeremy C. Stein: w11542
We develop a model that clarifies the respective advantages and disadvantages of academic and private-sector research. Our model assumes full protection of intellectual property rights at all stages of the development process, and hence does not rely on lack of appropriability or spillovers to generate a rationale for academic research. Instead, we focus on control-rights considerations, and argue that the fundamental tradeoff between academia and the private sector is one of creative control versus focus. By serving as a precommitment mechanism that allows scientists to freely pursue their own interests, academia can be indispensable for early-stage research. At the same time, the private sector%u2019s ability to direct scientists towards higher-payoff activities makes it more attractive ...
