Book Description
The objective of the study is to explore the relationship between TFP growth in the U.S. agricultural sector and R & D investments. To this end, an endogenous growth model is utilized to understand the link between TFP growth and technological change, and to examine how R & D investments lead to technical change. The main feature of the model is that R & D investments and technical change are endogenously determined in the economic system. The model in this study contributes to the existing literature on endogenous growth theory by incorporating a role for the public R & D sector. The public R & D sector helps the private R & D sector through subsidies; however it also may crowd out part of private R & D sector investment by competing with it when trying to create new and better technology. In the empirical analysis, first the link between TFP growth and technical change is explored using agricultural patent data as a proxy for technical change. Next, a patent production function is estimated with explanatory variables as public and private R & D investments. Then, the factors that determine private agricultural R & D investment are examined. To pursue these objectives, a system of equations is estimated with time series data for U.S. with seemingly unrelated regression technique. A negative relationship between TFP growth in the agricultural sector and agricultural patents is found, though the coefficient estimate is insignificant. Public R & D and extension services have a positive and significant impact on TFP. Public and private agricultural R & D investments have a positive effect on agricultural patents. It is also found that public R & D investment does not crowd out private R & D investment.

Book Description
The U.S. Department of Agriculture (USDA) requested that the Board on Agriculture and Natural Resources of the National Research Council (NRC) convene a panel of experts to examine whether publicly funded agricultural research has influenced the structure of U.S. agriculture and, if so, how. The Committee to Review the Role of Publicly Funded Agricultural Research on the Structure of U.S. Agriculture was asked to assess the role of public-sector agricultural research on changes in the size and numbers of farms, with particular emphasis on the evolution of very-large-scale operations.

Book Description
Much is written in the popular literature about the current pace of technological change. But do we have enough scientific knowledge about the sources and management of innovation to properly inform policymaking in technology dependent domains such as energy and the environment? While it is agreed that technological change does not 'fall from heaven like autumn leaves,' the theory, data, and models are deficient. The specific mechanisms that govern the rate and direction of inventive activity, the drivers and scope for incremental improvements that occur during technology diffusion, and the spillover effects that cross-fertilize technological innovations remain poorly understood. In a work that will interest serious readers of history, policy, and economics, the editors and their distinguished contributors offer a unique, single volume overview of the theoretical and empirical work on technological change. Beginning with a survey of existing research, they provide analysis and case studies in contexts such as medicine, agriculture, and power generation, paying particular attention to what technological change means for efficiency, productivity, and reduced environmental impacts. The book includes a historical analysis of technological change, an examination of the overall direction of technological change, and general theories about the sources of change. The contributors empirically test hypotheses of induced innovation and theories of institutional innovation. They propose ways to model induced technological change and evaluate its impact, and they consider issues such as uncertainty in technology returns, technology crossover effects, and clustering.
