Technological Change, Fuel Efficiency and Carbon Intensity in Electricity Generation: A Cross-Country Empirical Study AgEcon
Verdolini, Elena; Johnstone, Nick; Hascic, Ivan.
This paper provides an empirical analysis of the determinants of energy efficiency in fossil fuel electricity generation across 28 OECD countries over the period 1981-2006, with particular attention to the role played by technological development and the availability of energy efficient technologies in the market. This contribution is novel in three respects: first, empirically assess the effects of different determinants of energy efficiency, which include the input mix in electricity generation, the capacity ratio at which power plants are run, as well as the characteristics of the production technology. Second, we focus on the role of technological availability: using patent data for carefully selected innovations in fossil-fuel technologies, we build...

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.

An Integrated Assessment of Climate Change, Air Pollution, and Energy Security Policy AgEcon
Bollen, Johannes; Hers, Sebastiaan; van der Zwaan, Bob.
This article presents an integrated assessment of climate change, air pollution, and energy security policy. Basis of our analysis is the MERGE model, designed to study the interaction between the global economy, energy use, and the impacts of climate change. For our purposes we expanded MERGE with expressions that quantify damages incurred to regional economies as a result of air pollution and lack of energy security. One of the main findings of our cost-benefit analysis is that energy security policy alone does not decrease the use of oil: global oil consumption is only delayed by several decades and oil reserves are still practically depleted before the end of the 21st century. If, on the other hand, energy security policy is integrated with optimal...

ECONOMIC IMPACTS OF GENETICALLY MODIFIED CROPS IN CHINA AgEcon
Huang, Jikun; Hu, Ruifa; van Meijl, Hans; van Tongeren, Frank W..
China has made a major investment in biotechnology research. Genetically modified (GM) cotton is widely adopted and the list of GM technologies in trials is impressive. At the same time there is an active debate on when China should commercialize its GM food crops. The overall goal of this paper is to provide an economy-wide assessment of these issues under various scenarios. Based on a unique data from empirical micro-level study and field trial in China and a modified GTAP model, our results indicate that the development of biotechnology has an important impact on China's production, trade and welfare. Welfare gains far outweigh the public biotechnology research expenditures. Most gains occur inside China. Policy makers should put less weight on...

Governing the Co-existence of GM Crops: Ex-Ante Regulation and Ex-Post Liability under Uncertainty and Irreversibility AgEcon
Beckmann, Volker; Soregaroli, Claudio; Wesseler, Justus.
The future institutional environment for the co-existence of genetically modified (GM) crops, conventional crops and organic crops in Europe combines measures of ex-ante regulation and ex-post liability rules. Against this background we ask the following two questions: How does ex-ante regulation and ex-post liability under irreversibility and uncertainty affect the adoption of GM crops? What are the implications for regional agglomeration of GM and non-GM crops? Ex-ante regulations and ex-post liabilities for using GM crops will induce additional costs. These costs are modelled in a classical way. The model is advanced by including irreversibility and uncertainty and taking into account transaction costs of negotiating possible solutions with neighbouring...

Microeconomic Approaches to Development: Schooling, Learning, and Growth AgEcon
Rosenzweig, Mark R..
I illustrate the variety of approaches to development issues microeconomists employ, focusing on studies that illuminate and quantify the major mechanisms posited by growth theorists who highlight the role of education in fostering growth. I begin with a basic issue: what are the returns to schooling? I discuss microeconomic studies that estimate schooling returns using alternative approaches to estimating wage equations, which require assumptions that are unlikely to be met in low-income countries, looking at inferences based on how education interacts with policy and technological changes in the labor and marriage markets. I then review research addressing whether schooling facilitates learning, or merely imparts knowledge, and whether there is social...

DETERMINANTS OF FOOD INDUSTRY PERFORMANCE – SURVEY DATA AND REGRESSIONS FOR DENMARK AgEcon
Furtan, William Hartley; Sauer, Johannes.
This paper investigates empirically the determinants of firms’ performance in the agrifood sector by using recent survey data for Denmark. Treating sales per employee as a proxy for value added we estimate several bootstrapped regression models to draw conclusions on the marginal effects of potential performance determinants such as the form and nature of ownership, stage of the food chain and commodity sector, new product development, staff quality, firms’ competitive stance, and elements of firms’ strategy. To draw robust inferences we apply, besides the ordinary heteroscedasticity corrected Tobit ML-estimator, a nonparametric least absolute deviations estimator (LAD/CLAD) based on a quantile regression...

Human Capital, Innovation, and Climate Policy: An Integrated Assessment AgEcon
Carraro, Carlo; De Cian, Enrica; Tavoni, Massimo.
This paper looks at the interplay between human capital and innovation in the presence of climate and educational policies. Using recent empirical estimates, human capital and general purpose R&D are introduced in an integrated assessment model that has been extensively applied to study climate change mitigation. Our results suggest that climate policy stimulates general purpose as well as clean energy R&D but reduces the incentive to invest in human capital formation. Human capital increases the productivity of labour and the complementarity between labour and energy drives its pollution-using effect (direct effect). When human capital is an essential input in the production of generic and energy dedicated knowledge, the crowding out induced by...

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...

Neoclassical Growth, Environment and Technological Change: The Environmental Kuznets Curve AgEcon
Rubio, S.J.; Garcia, J.R.; Hueso, J.L..
The paper investigates socially optimal patterns of economic growth and environmental quality in a neoclassical growth model with endogenous technological progress. In the model, the environmental quality affects positively not only to utility but also to production. However, cleaner technologies can be used in the economy whether a part of the output is used in environmentally oriented R&D. In this framework, if the initial level of capital is low then the shadow price of a cleaner technology is low relative to the cost of developing it given by the marginal utility of consumption and it is not worth investing in R&D. Thus, there will be a first stage of growth based only on the accumulation of capital with a decreasing environmental quality until...
