We test three hypotheses regarding changes in supervisory toughness' and their effects on bank lending. The data provide modest support for all three hypotheses that there was an increase in toughness during the credit crunch period (1989-1992), that there was a decline in toughness during the...

We test three hypotheses regarding changes in supervisory quot;toughnessquot; and their effects on bank lending. The data provide modest support for all three hypotheses that there was an increase in toughness during the credit crunch period (1989-1992), that there was a decline in toughness...

While there is widespread agreement among economists and management scholars that knowledge spillovers exist and have important economic consequences, researchers know substantially less about the quot;micro mechanismsquot; of spillovers -- about the degree to which they are geographically...

Alan Garber and Jonathan Skinner (2008) famously conjectured that the US health care system was “uniquely inefficient” relative to other countries. We test this idea using cross-country data on prescription drug sales newly linked with an arguably objective measure of relative therapeutic...

This paper examines how pharmaceutical firms have responded to changes in intellectual property rights and trade barriers that legalized "parallel imports" within the European Union. The threat of arbitrage by parallel traders reduces the ability of firms to price discriminate across countries....

We examine the relationship between patent protection for pharmaceuticals and investment in development of new drugs. Patent protection has increased around the world as a consequence of the TRIPS Agreement, which specifies minimum levels of intellectual property protection for members of the...
