This paper is a re-examination of the relationship between research and development (R&D) activity and total factor productivity (TFP) at the industry level during the period extending from the early 1960's to the mid-1970's. The data base consists of NSF data on applied R&D expenditures by...

In this paper we investigate the incidence of measurement errors in two independent estimates of long-term price change, within the framework of "multiple indicators" models of price measurement. We develop estimates of the measurement-error variances associated with both the Producer Price...

Longitudinal, disease-level data are used to analyze the impact of pharmaceutical innovation on longevity (mean age at death), hospital utilization, and medical expenditure in Greece during the period 1995 - 2010. The estimates indicate that pharmaceutical innovation increased mean age at death...

Dean Baker and Adriane Fugh-Berman have published a critique of a study I performed in 2007, entitled "Why has longevity increased more in some states than in others?ʺ One of the conclusions I drew from that study was that medical innovation accounts for a substantial portion of recent...

There are two types of prescription drug cost offsets. The first type of cost offset - from prescription drug use - is primarily about the effect of changes in drug quantity (e.g. due to changes in out-of-pocket drug costs) on other medical costs. The second type of cost offset - the cost offset...

I investigate the contribution of pharmaceutical innovation to recent longevity growth in Germany and France. First, I examine the effect of the vintage of prescription drugs (and other variables) on the life expectancy and age-adjusted mortality rates of residents of Germany, using...

We update and extend our previous study of the effect of drug age -- years since FDA approval -- on total medical expenditure, in several respects. The estimates indicate that, in the entire population, a reduction in the age of drugs utilized reduces non-drug expenditure 7.2 times as much as it...

This paper reviews the literature on the relationship of economic growth to the education levels of the labor force. The emphasis is on Ben-Porath's contribution to some of the issues in this field: the endogeneity of schooling, the role of the public sector as an `absorber' of educated labor,...

This note reviews the history of the 'residual,' from its earliest articulation in Copeland (1937) to its codification in Solow (1957), describing the various earlier contributions by Tinbergen, Stigler, Schmookler, Fabricant, Kendrick, Abramovitz and others
