In this paper we develop measures of economic capacity output and economic capacity utilization for firms producing multiple outputs and having one or .ore quasi-fixed inputs. Although we produce an impossibility theorem showing that based only on the assumption of cost minimization, the concept...

In this paper we calculate and analyze the automobile industries cost and productivity experience during the 1970 's in Canada, the U.S.and Japan. Utilizing an econometric cost function methodology, we are able to isolate the major source of short-run disequilibrium in this industry-variations'...

In this paper we present for the first time estimates of cost and efficiency differences between U.S. and Japanese producers based on an econometric cost function methodology rather than the accounting frameworks previously used. We demonstrate that the cost difference estimates for 1979 which...

Drugs like bevacizumab ($50,000 per treatment episode) and ipilimumab ($120,000 per episode) have fueled the perception that the launch prices of anticancer drugs are increasing over time. Using an original dataset of 58 anticancer drugs approved between 1995 and 2013, we find that launch...

We examine six molecules facing initial loss of US exclusivity (LOE, from patent expiration or challenges) between June 2009 and May 2013 that were among the 50 most prescribed molecules in May 2013. We examine prices per day of therapy (from the perspective of average revenue received by retail...

We examine the impact of loss of U.S. patent exclusivity (LOE) on the prices and utilization of specialty drugs between 2001 and 2007. We limit our empirical cohort to drugs commonly used to treat cancer and base our analyses on nationally representative data from IMS Health. We begin by...

We estimate hedonic price indexes for clinical trial research, an important component of biomedical R&D, using a large sample of agreements between trial sponsors and clinical investigators obtained from Medidata Solutions Worldwide Inc. Nominal prices measured as total grant cost per patient...

We compute quality-adjusted price indexes for Personal Digital Assistants (PDAs) for the period 1999-2004, using data on prices and characteristics of 203 models sold by 12 manufacturers. The PDA market is growing in size, it is technologically dynamic with very substantial changes in measured...
