Is public R&D spending complementary and thus “additional” to private R&D spending, or does it substitute for and tend to “crowd out” private R&D? Conflicting answers are given to this question. We survey the body of available econometric evidence accumulated over the past 35 years. A...

This paper is a first step toward closing the analytical gap in the extensive literature on the results of interactions between public and private R&D expenditures, and their joint effects on the economy. Earlier studies frequently report contradictory estimates of the response of company...

Early contributions to the academic literature on free/libre and open source software (F/LOSS) movements have been directed primarily at identifying the motivations that account for the sustained and often intensive involvement of many people in this non-contractual and unremunerated productive...

The three most extensively cited papers by Zvi Griliches deal with the diffusion of innovations, distributed lags and the sources of the growth of measured total factor productivity, respectively. The close economic connections between these dynamic phenomena remained largely unexplored and were...

This paper aims to develop a stochastic simulation structure capable of describing the decentralized, micro-level decisions that allocate programming resources both within and among open source/free software (OS/FS) projects, and that thereby generate an array of OS/FS system products each of...

The progress of scientific and technological knowledge is a cumulative process, one that depends in the long?run on the rapid and widespread disclosure of new findings, so that they may be rapidly discarded if unreliable, or confirmed and brought into fruitful conjunction with other bodies of...

The concept of path dependence refers to a property of contingent, non- reversible dynamical processes, including a wide array of biological and social processes that can properly be described as 'evolutionary.' To dispell existing confusions in the literature, and clarify the meaning and...

Presented to the International Symposium on ECONOMIC CHALLENGES OF THE 21ST CENTURY IN HISTORICAL PERSPECTIVE, Oxford, England, 2nd-4th July, 1999 Celebrating the Scholarly Career of Charles H. Feinstein, FBA. Re- examination of early twentieth century American productivity growth experience...

A marked acceleration of total factor productivity (TFP) growth in U.S. manufacturing followed World War I. This development contributed substantially to the absolute and relative rise of the domestic economy's aggregate TFP residual, which is observed when the 'growth accounts' for the first...
