The measurement of the impact of technical change has received significant attention within the economics literature. One popular method of quantifying the impact of technical change is the use of growth accounting index numbers. However, in a recent article Nelson and Pack (1999) criticise the use of such index numbers in situations where technical change is likely to be biased in favour of one or other inputs. In particular they criticise the common approach of applying observed cost shares, as proxies for partial output elasticities, to weight the change in quantities which they claim is only valid under Hicks neutrality. Recent advances in the measurement of product and factor biases of technical change developed by Balcombe et al (2000) provide a relatively straight-forward means of correcting product and factor shares in the face of biased technical progress.

This paper demonstrates the correction of both revenue and cost shares used in the construction of a TFP index for UK agriculture over the period 1953 to 2000 using both revenue and cost function share equations appended with stochastic latent variables to capture the bias effect. Technical progress is shown to be biased between both individual input and output groups. Output and input quantity aggregates are then constructed using both observed and corrected share weights and the resulting TFPs are compared. There does appear to be some significant bias in TFP if the effect of biased technical progress is not taken into account when constructing the weights.

Using a partial equilibrium model of world agriculture, we investigate the multilateral removal of all border taxes and farm programs and their distortion of world agricultural markets. These distortions have significant terms-of-trade effects. World trade is also significantly impacted by both types of distortions. Trade expansion is substantial for most commodities, especially dairy, meats, and vegetable oils. Net agricultural and food exporters (Brazil, Australia, and Argentina) emerge with expanded exports; whereas net importing countries with limited distortions before liberalization are penalized by higher world markets prices and reduced imports. The US gains significant export shares in livestock products and imports more dairy products. Without protection and domestic subsidies, the EU loses many of its livestock and dairy export markets.

This paper is aiming at an analysis of Rural Development Programs (RDP) in Turkey with special reference to EU Rural Development Policies, Programs and implementations. Concerning to Turkish Programs, it has been reported that over the last 30 years and more particularly during the planned Development Period, special efforts have been made to gain Rural development experience in Turkey. In each five year Development Planning period (DPP), particular goals and instruments of policy for both agricultural development and that of rural areas have been specified and determined. Integrated Rural development Projects and some other typical Rural Development Projects have also been implemented in line with the targets given in each planning period.

Изд-во: Edward Elgar, 2005, 240 с.
This unique textbook provides a comprehensive critical analysis of modern theories, concepts and effects relating to transnational corporations and international production. Its user-friendly presentation includes boxes to highlight key concepts as well as suggestions for further reading. The text begins with a clear and concise discussion of basic concepts, and goes on to examine various theoretical approaches, topics and authors including:. Hymer, Vernon, Knickerbocker, Aliber, Dunning, Cantwell, Cowling and Sugden. the Internalisation Theory, the Scandinavian School, and the New Trade Theory approaches. Pre-WWII Marxist and neoclassical approaches to international investment. Finally, Grazia Ietto-Gillies deals with methodological issues in the assessment of effects as well as with specific effects on performance, labour, international trade and the balance of payments. Bringing together wide-ranging research literature on TNCs for the first time, this textbook will be invaluable to post graduate and advance undergraduate students of a variety of disciplines including business/international business, economics, international relations, and development studies. Lecturers and researchers wishing to familiarize themselves with the theoretical developments of the subject will also find the book of enormous interest.

This paper proposes an Economic Drought Management Index (EDMI) that could assist water managers to inter-temporally manage water reservoirs. The index’s main appeal is that it can be easily interpreted and that encompasses in a single number hydrological processes, structural constraints, water institutions’ rules and the economic benefits of the customers served from the supply system. An empirical application of EDMIs is performed for two irrigation districts in Andalusia (Southern Spain), that are managed under different institutional arrangements. Results for one district show that the region’s vulnerability to drought could be reduced following the interpretation of the EDMIs. For the other district, the index shows that water stocks are managed under nearly optimal criteria. This last result shows that there is an efficient level of drought vulnerability, and that increasing supply security levels would result in welfare losses.

During recent years, dramatic changes in the world food system have led to unprecedented competition between agribusiness firms. To compete in this environment, agricultural cooperatives should invest substantially in long-term activities such as R&D and advertisement. Co-operatives have a difficult problem in acquiring equity capital because the residual claimant (benefactor) is the patron of the firm, not the investor. This organizational design poses to cooperatives three investment constraints:
a) the free rider problem,
b) the horizon problem, and
c) the portfolio problem.
Empirical analysis utilizing a latent variable structural equation model and a large dual response survey suggests that in the U.S. member-patrons are more likely to invest in co-operatives which adopt well defined property rights policies and structures than traditional co-operatives characterized by vaguely-defined property right structures. Agribusiness co-operatives in the European Union are gradually adopting long-term financing methods that possess one or more of the characteristics found in successful U.S. ‘New Generation Cooperatives.’ However, it seems that they have paid less attention in designing their organizational structures (e.g., membership policies). This may inhibit their efforts to gain a competitive advantage over investor-owned firms.

This paper assesses and quantifies the consequences of world trade liberalization in agriculture on trade and food security of Sudan. Sudan, with the agricultural sector as the main sector of economy, is characterized by its small open economy, and is classified as one of the least developed countries. Thus, Sudan becomes more vulnerable to any changes in international agricultural markets. The liberalization of international agricultural trade has a great influence on Sudan's food security and on the whole economy. An extended form of a multi-market model for Sudan is developed and used for the analysis. The model embodies important characteristics of agriculture in Sudan like substitution effects and stages of production.

As agriculture is the main sector of Sudan's economy, the model is extended to explicitly integrate some of the key important macroeconomic linkages, and to establish certain feedback effects between agriculture and the macro-economy. The model simulations reveal that a higher world market price would overall lead to measurable gains in food security and agricultural trade of the country. However, when the effect of a higher cost of production is considered, the positive results are reversed. Furthermore, the results of the model simulations show that the domestic policy environment matters very much with respect to the potential impact of world trade liberalization of agriculture. The paper concludes that Sudan should reorient its national policies towards export promotion in order to benefit from the new emerging trading opportunities in world markets. However, to capture a greater benefit from the new environment in the international markets, Sudan should consider and manage carefully all factors, domestically or internationally - e.g. quality standard, loss of preference, dumping effects - that hinder its economic and trade growth.

To improve the welfare of the rural poor and keep them in the countryside, the government has been spending 40% of the value of agricultural GDP on agricultural support services. But can investment make smallholder agriculture prosperous in such adverse conditions? This paper derives an answer by applying a two-output six-input stochastic translog distance function, with inefficiency effects and biased technical change to panel data for the 18 districts and the commercial sector, from 1979 to 1996. This model demonstrates that herds are the most important input, followed by draft power, land and seeds. Multilateral indices for technical change, technical efficiency and total factor productivity (TFP) show that the technology level of the commercial sector is more than six times that of traditional agriculture and that the gap has been increasing, due to technological regression in traditional agriculture and modest progress in the commercial sector. Since the levels of efficiency are similar, the same pattern is repeated by the TFP indices. This result highlights the policy dilemma of the trade-off between efficiency and equity objectives.

This paper examines Japanese foreign exchanges interventions from April 1991 to March 2001 based on newly disclosed official data. All the yen-selling (dollar-purchasing) interventions were carried out when the yen/dollar rate was below 125, while all the yen-purchasing (dollar-selling) interventions were carried out when the yen/dollar was above 125. The Japanese monetary authorities, by buying the dollar low and selling it high, have produced large profits, in terms of realized capital gains, unrealized capital gains, and carrying (interest rate differential) profits, from interventions during the ten years. Profits amounted to 9 trillion yen (2% of GDP) in 10 years. Interventions are found to be effective in the second half of the 1990s, when daily yen/dollar exchange rate changes were regressed on various factors including interventions. The US interventions in the 1990s were always accompanied by the Japanese interventions. The joint interventions were found to be 20-50 times more effective than the Japanese unilateral interventions. Japanese interventions were found to be prompted by rapid changes in the yen/dollar rate and the deviation from the long-run mean (say, 125 yen). The interventions in the second half were less predictable than the first half.

This book helps explain one of the most intriguing and politically salient puzzles in comparative political economy: why some countries have much higher unemployment rates than others. Contrary to new classical economics the focus is on explaining distribution and equilibrium unemployment, and contrary to neo-corporatist theory the role of monetary policy and rational expectation is integral to the analysis. The book makes two central arguments. The first is that monetary policies affect equilibrium employment whenever wages are set above the firm level. The second argument focuses on the distributive effects of different institutions, and models institutional design as a strategic game between partisan governments and cross-class alliances of unions and employers.
