Seminal papers of Solow (1957) and Swan (1956) stimulated debate among economists on the role of technical change in productivity improvements and for that matter economic growth. The consensus is that technological change accounts for a significant proportion of gross national product (GNP)...

The objective of this study is to analyze technical change and the role of research and development (R&D) spillovers in this process for the U.S. agricultural sector. This study is composed of both a theoretical and an empirical analysis. In the theoretical analysis, a quality innovation model...

We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 45 years, looking for evidence of recent changes in growth patterns using an improved nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of...

This study analyzes sources of productivity change in petroleum exploration and development in the United States over the last ten years. There have been several major developments in the industry over the last decade that have led to dramatic reductions in the cost of finding and developing oil...

In this paper we develop a cost index-based measure of the expected consumer welfare gains from innovation in electricity generation technologies. To illustrate our approach, we estimate how much better off consumers would be from 2000 to 2020 as renewable energy technologies continue to be...

Building on the ontology of evolutionary realism recently proposed by Dopfer and Potts (forthcoming), we develop an analytical framework for evolutionary economics with a micro-meso-macro architecture. The motive for reconception is to make clear the highly complex and emergent nature of...

Profitability change can be decomposed into the product of a total factor productivity (TFP) index and an index measuring changes in relative prices. Many TFP indexes can be further decomposed into measures of technical change, technical efficiency change, scale efficiency change and mix...
