Última A Politico-Economic Model of Aging, Technology Adoption and Growth AgEcon Lancia, Francesco; Prarolo, Giovanni. Over the past century, all OECD countries have been characterized by a dramatic increase in economic conditions, life expectancy and educational attainment. This paper provides a positive theory that explains how an economy might evolve when the longevity of its citizens both influences and is influenced by the process of economic development. We propose a three periods OLG model where agents, during their lifetime, cover different economic roles characterized by different incentive schemes and time horizon. Agents’ decisions embrace two dimensions: the private choice about education and the public one upon innovation policy. The theory focuses on the crucial role played by heterogeneous interests in determining innovation policies, which are one of the...

Ano: 2005 URL: http://purl.umn.edu/19262 An Outlook for the Biofuels Industry in the Southern United States AgEcon Crooks, Anthony C.; Dunn, John R.. Two seemingly unrelated topics are discussed- an outlook for biofuels in the southern United States, along with an overview of the important role that information technology is playing in the fuel ethanol industry. The outlook discussion is limited to issues involving the two principal biofuels, fuel ethanol and biodiesel, and their respective feed stocks, corn and soybean oil. The two topics are linked with a description of how information technology (IT) has enabled the development of the fuel ethanol franchise and a discussion of how IT is changing the very nature of biofuel operations.

Ano: 2006 URL: http://purl.umn.edu/43771 Chinese Manufacturing Performance in Comparative Perspective, 1980-2002 AgEcon Szirmai, Adam; Ren, Ruoen; Bai, Manyin. This paper uses the detailed information in the 1995 Census of Industrial Production as a benchmark for analysing the coverage, concepts and consistency of published statistical series. On the basis of the analysis, the paper proposes a series of adjustments which result in more consistent long-run series of labour productivity for 21 manufacturing sectors from 1980-2002. For purposes of international comparisons with the USA, the paper subsequently presents industry of origin unit value ratios for the benchmark year 1995. These are used to convert Chinese value added into US dollars. In 2002, value added for the statistically well-covered sectors of Chinese manufacturing was 43 per cent of US value added, against 12 per cent in 1980. The comparative...

Ano: 2005 URL: http://purl.umn.edu/28525 Does agricultural growth have a causal effect on manufacturing growth? AgEcon Shifa, Abdulaziz B.. Though the role of agricultural growth for manufacturing growth has been at the center of the discourse on economic development, empirically identifying the causal effect of agricultural growth on manufacturing growth has remained illusive for the correlation between the two doesn't necessarily imply causality. This paper attempts to overcome the identification problem. Since agriculture is heavily dependent on the weather, random weather variations are used as instruments to identify the causal impact of agricultural growth on manufacturing growth. Results show that agricultural growth has a significant positive impact on manufacturing growth. The impact is higher the higher is agriculture's share in the economy (as measured by GDP and employment share)....

The paper develops a metric of structural transformation that can account for the production of new varieties of goods embodying advancements in technological know-how and design. Our measure captures the dynamics of an economy’s transformation and can be viewed as an extension of Hausmann and Klinger’s static measure. We apply our measure to four-digit-level SITC trade data of China, Malaysia, and Ghana over the period 1962–2000. The results show that two important factors characterize the rapid transformation of the Chinese economy: the high proximity of its export basket to three main industrial clusters—capital goods, consumer durable goods, and intermediate inputs—and the increase in the values of the new goods belonging to those three clusters....

Ano: 2009 URL: http://purl.umn.edu/47176 Learning-by-Doing and the Choice of Technology: The Role of Patience AgEcon Karp, Larry S.; Lee, In Ho. If agents learn-by-doing and are myopic, less advanced firms might adopt new technologies while more advanced firms stick with the old technology. This kind of overtaking can also occur if agents are forward looking and have high discount rates. However, overtaking never occurs if agents are sufficiently patient. A finite discount rate increases the set of states at which agents adopt new technologies, so more patient agents tend to upgrade their technology more frequently.

Ano: 2000 URL: http://purl.umn.edu/25108 On the Green Side of Trade Competitiveness? Environmental Policies and Innovation in the EU AgEcon Valeria, Costantini; Mazzanti, Massimiliano. This paper aims to explore how the competitiveness of the EU economy, here captured by export dynamics over the medium run (1996-2007), has been affected by environmental regulation both on the public and private sector side. The strong and weak versions of the Porter hypothesis are tested by specifying the export dynamics of five aggregated manufacturing sectors classified by their technological or environmental content using a dynamic panel data estimator applied to a theoretically-based gravity model. When testing the strong version on export performances of manufacturing sectors, the overall effect of environmental policies does not conflict with export competitiveness. When testing the weak version using export flows of environmental goods,...

Ano: 2010 URL: http://purl.umn.edu/92910 Productivity and Economic Growth in Tunisian Agriculture: An Empirical Evidence AgEcon Dhehibi, Boubaker; Lachaal, Lassaad. This paper analyse the patterns of productivity and economic growth in the Tunisian agriculture during the 1961–2000. Results indicated that agriculture output growth where high in both the 1961–1970 and the 1971–1980 periods but decreased during the 1991–2000 period. Average output growth exceeded 6% during the 1981–1990 period, the average output growth during 1991–2000 had fallen to 4%. Over the whole period, capital was the most important contributor to output growth and labour is considered as the least significant contributor to economic growth. Total factor productivity contribution to output growth decreased from 4.64% in 1961–1970 to 2.86% in 1971–1980. In contrast, this contribution increased in 1981-1990 to close the 4.38%.

Ano: 2006 URL: http://purl.umn.edu/25707 Profits and Politics: Coordinating Technology Adoption in Agriculture AgEcon Pande, Rohini. This paper examines the political economy of coordination in a simple two-sector model in which individuals' choice of agricultural technology affects industrialization. We demonstrate the existence of multiple equilibria; the economy is either characterized by the use of a traditional agricultural technology and a low level of industrialization or the use of a mechanized technology and a high level of industrialization. Relative to the traditional technology, the mechanized technology increases output but leaves some population groups worse off. We show that the distributional implications of choosing the mechanized technology restrict the possibility of Pareto-improving coordination by an elected policy-maker, even when we allow for income redistribution.

Ano: 2005 URL: http://purl.umn.edu/28383 R&D, Innovation and Growth: Evidence from Four Manufacturing Sectors in OECD Countries AgEcon Ulku, Hulya. This paper provides an empirical analysis of the relationship between R&D intensity, rate of innovation and the growth rate of output in four manufacturing sectors from 17 OECD countries. The findings suggest that the knowledge stock is the main determinant of innovation in all four manufacturing sectors and that R&D intensity increases innovation in the chemicals and the electrical and electronics sector. In addition, the rate of innovation has a positive effect on the growth rate of output in all sectors except for the drugs and medical sector. These results lend strong support for the non-scale endogenous growth models. *I am grateful to Adam Jaffe for his invaluable suggestions and comments.

Ano: 2005 URL: http://purl.umn.edu/30542 Scarcity and Growth in the New Millennium: Summary AgEcon Simpson, R. David; Toman, Michael; Ayres, Robert U.. In their 1963 classic Scarcity and Growth Howard Barnett and Chandler Morse argued that resource scarcity did not threaten economic growth. A second investigation in the late 1970s, Scarcity and Growth Reconsidered, reached largely the same conclusion. The 25 years since that work was published have witnessed many developments. The message of Scarcity and Growth that depletion of market resources was not a problem has given way to a concern that "new scarcities" of environmental quality, global climate, and biological diversity are emerging. Resources for the Future recently assembled a distinguished group of international scholars to again address scarcity and growth. This paper describes their charge and summarizes their findings.

Ano: 2004 URL: http://purl.umn.edu/10835 SME Performance, Innovation and Networking Evidence on Complementarities for a Local Economic System AgEcon Mazzanti, Massimiliano; Mancinelli, Susanna. The paper addresses the relevancy of networking activities and R&D as main drivers of productivity performance and ouput innovation, for small and medium enterprises (SME) playing in a local economic system. Given the intangible nature of many techno organisational innovation and networking strategies, original recent survey data for manufacturing and services are exploited. The aim is to provide new evidence on the complementarity relationships concerning different networking activities and R&D in a local SME oriented system in Northern Italy. We first introduce a methodological framework to empirically test complementarity among R&D and networking, in a discrete setting. Secondly, we consequently present empirical evidence on productivity...

Ano: 2010 URL: http://purl.umn.edu/92360 Technology Adoption And Pest Control Strategies Among UK Cereal Farmers: Evidence from Parametric and Nonparametric Count Data Models AgEcon Sharma, Abhijit; Bailey, Alastair; Fraser, Iain. This paper examines technology adoption and integrated pest management strategies employed by UK farmers, using both parametric and nonparametric methods. We employ a unique survey data set collected from UK cereal farmers to assess the determinants of technology adoption in relation to pest management. Our preferred model specification is nonparametric which makes use of the recently developed methods of Li and Racine (2007) and Racine and Li (2004). These methods allow us to combine categorical and continuous data and thereby avoid sample splitting and resulting efficiency losses. Our analysis reveals that total area farmed is positively related to the number of technologies adopted, whereas age is negatively related. We also find evidence of...

Ano: 2009 URL: http://purl.umn.edu/51335 Technology Change: Sources and Impediments AgEcon Ranis, Gustav; Irons, Mallory; Huang, Yanjing. There is little doubt that technology change, both in terms of its process and quality dimensions, represents the principal driving force to explain comparative economic performance at both micro and macro levels. This paper examines the sources of technology change and the impediments to the full realization of its opportunities, both abstractly and in the context of a comparison among six typologically diverse developing countries. Among the external sources, we examine the roles of trade, foreign patents and FDI; among the internal sources we examine the roles of investment, domestic R&D, domestic patents, S&T personnel and secondary education alternatives. Among impediments, we analyze certain public and private policy frameworks which tend...

Ano: 2011 URL: http://purl.umn.edu/118647 The Sophistication and Diversification of the African Agricultural Sector: A Product Space Approach AgEcon Badibanga, Thaddee Mutumba; Ulimwengu, John M.. We use the concept of the product space to analyze the key features of the transformation process in Africa with a focus on the agricultural sector. Between 1962 and 2008, we find that both specialization and diversification occur for the overall economy and across sectors. Our findings also confirm that the transformation of the African economy is driven primarily by the increasing specialization of nonagricultural exports. However, the transformation process is still moving more slowly than that of an emerging economy such as Brazil. The index of specialization of agricultural exports grew at a modest annual rate of 2.1 percent between 1962 and 2008, compared to 5.0 percent for nonagricultural exports and 4.1 percent for the overall economy. Although...

The probability of a business paying various amounts of money for an e-commerce presence ultimately depends on demographic features, experiences with e-commerce from a buyer’s and seller’s perspective, technological expertise, and knowledge of e-commerce opportunities and limitations. Estimating functions to assign probabilities associated with the willingness to pay for an e-commerce presence will assist in forecasting regional likelihood of certain profiles paying various monetary amounts for an e-commerce presence. In addition, if services are provided at no cost by a third party, value to a society will be maximized by selecting profiles with the highest willingness to pay.
