| We critically review the Kyoto Protocol and thirteen alternative policy architectures for addressing the threat of global climate change. We employ six criteria to evaluate the policy proposals: environmental outcome, dynamic efficiency, cost effectiveness, equity, flexibility in the presence of new information, and incentives for participation and compliance. The Kyoto Protocol does not fare well on a number of criteria, but none of the alternative proposals fare well along all six dimensions. We identify several major themes among the alternative proposals: Kyoto is "too little, too fast"; developing countries should play a more substantial role and receive incentives to participate; implementation should focus on market-based approaches, especially... |

| Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains... |

| Three sesame genotypes (Rama, SI 1666 and IC 21706) were treated with physical (γ-rays: 200 Gy, 400 Gy or 600 Gy) or chemical (ethyl methane sulphonate, EMS: 0.5%, 1.0%, 1.5% or 2.0%) mutagens and their mutagenic effectiveness and efficiency were estimated in the M2 generation. The M3 generation was used to identify the most effective mutagen and dose for induction of mutations. The average effectiveness of EMS was much higher than γ-rays. The lowest dose of γ-rays (200 Gy) and the lowest concentration of EMS (0.5%) showed the highest mutagenic efficiency in all genotypes. Analysis of the M3 generation data based on parameters such as the variance ratio and the difference in residual variances derived from the model of Montalván and Ando indicated that... |

| Milk production is seasonal in many European countries. While quantity seasonality poses capacity management problems for dairy processors, a European Union policy goal is to reduce price seasonality. After developing a model of endogenous seasonality, we study the effects of three E.U. policies on production decisions. These are private storage subsidies, production removals, and production quotas. When cost functions are seasonal in a specified way, then arbitrage opportunities interact with storage subsidies to reduce both price and consumption seasonality. But production seasonality likely increases because storage subsidies promote temporal market integration. Conditions are identified under which product market interventions increase quantity... |

| A külföldi tőke érdeklődése a magyar mezőgazdaság iránt 87,2 milliárd forint sajáttőke-résszel 2002-ben érte el a csúcsot a KSH adatai szerint. Forintárfolya-mon számolva 1993 és 2001 között 6,3-szeresére nőtt a jegyzett tőkében a külföl-di tőke összege, euróban számolva 2,6-szeres volt a növekedés. A mezőgazdasági termelésben kettős könyvelést vezető gazdaságoknál a kül-földi tőke a jegyzett tőkéből 7,3 milliárd forintról (1993. évi adat) 2000-re 31,5 milliárd forintra emelkedett, majd 2003-ra 24,5 milliárdra csökkent. A két év alatti több mint 20 százalékos visszaesés a külföldi tőke érdekvesztését jelzi. A legnagyobb csökkenés a gabonafélék, egyéb máshova nem sorolt növények szak-ágazatban volt a legnagyobb. A külföldi tőke 2/3-a a növénytermelési és... |

| Hazánkban az utóbbi években egyre nagyobb területeken folyik alkaloida és étkezési mák termelése. Megállapítható, hogy nem igazolódtak be azok a várakozások, melyek az uniós csatlakozástól a máktermelés csökkenését várták, annak ellenére, hogy az unió korlátozta egyes hazai, magasabb alkaloidatartalmú fajták termelését. Vizsgálataink alapján megállapítható, hogy a máktermelés magas hektáronkénti termelési költsége ellenére jövedelmező. Ha a hazai máktermelést az 1960-as évek szintjére emelnék, akkor az hozzájárulhatna a napjainkban fennmaradásukért és mindennapi megélhetésükért küzdő – elsősorban a szegényebb kelet-magyarországi régiókban – gazdálkodók megélhetéséhez. ------------------------------------- The area used for growing poppy seed for human... |

| ABSTRACT The objective of this study was to identify types of production system and their main indicators on bioeconomic efficiency, using qualitative and quantitative methods to evaluate beef cattle farms in the western region of the state of Rio Grande do Sul. A survey was carried out with 43 farmers operating in the western region of that state. All farms operated with complete cycle production systems in areas larger or equal to 900 ha. A qualitative questionnaire with binary answers and a quantitative questionnaire with numerical answers were applied. Technology and Management drivers were used for the calculation of the efficiency index of farmers obtained by both questionnaires. Farmers were divided into three clusters: low-efficiency level (LEL),... |

| Declining yields of maize as a result of Striga infestation has necessitated a new technology known as Imazapyr-resistant maize (IRM) to contain the problem. As a result, research and development initiatives with substantial participation of the private sector to transfer this new technology to farmers have been made in western Kenya. This study therefore assesses the adoption of IRM variety and efficiency levels of farmers in western Kenya. A multi-stage sampling technique was used to select a total of 600 households from Nyanza and Western provinces for this study. Tobit model and stochastic production frontier analysis were the analytical methods. Results show that age, education, maize production gap, risk, contact with extension agents, lack of seeds,... |

| This study examines the impact of agriculture-specific and economywide institutional reform in Russia and Ukraine on the productivity and efficiency of agricultural production. Production in the agricultural sector in Russia and Ukraine has fallen since reforms began in 1992. The decline is to a certain extent an inevitable result of reform as input and output prices realign to world prices. However, some of the decline is due to incomplete agriculture-specific and economywide institutional reform. Russia and Ukraine have the potential to increase grain exports significantly if reforms are implemented: the most likely scenario projects that wheat and barley exports from Russia and Ukraine could double from current projections, reaching 21 million metric... |

| Increased productivity is a key to a healthy and thriving economy. Consequently, the trend in productivity, economywide, is one of the most closely watched of our common economic performance indicators. Agriculture, in particular, has been a very successful sector of the U.S. economy in terms of productivity growth. The U.S. farm sector has provided an abundance of output while using inputs efficiently. Agricultural productivity growth has been an important source of U.S. economic growth throughout the century, but the years since 1940 have seen an even faster growth in agricultural productivity. The annual average increase in productivity from 1948 to 1994 was 1.94 percent. This reflects an annual growth in output of 1.88 percent per year and an actual... |

| During three-hundred-year history of the market economy, the main sources of wealth creation have changed from the natural resources (mainly land and relatively unskilled labor with the exception of the master craftsman), tangible material assets (buildings, machinery and equipment, funds) to intangible assets (knowledge and information of all types) that may be contained in the people, organizations, or physical resources. In the later period of the twentieth century, science has acquired the features of direct production force. The term direct implies that unlike the relationship which existed between science and production in the IXX century, where scientific advances was incorporated through the physical labor in the tools, which, in turn, created new... |
