The Impacts of Redesigning European Agricultural Support

The objective of this paper is to assess the impact of decoupling at the individual member state level in the European Union and in non-member regions of liberalizing domestic support in the EU. Three scenarios are analysed to illustrate the impacts of eliminating or decoupling the European agricultural support. We found that the existing domestic support payments in the EU are indeed coupled to production and hence affect production decisions and distort international trade with adverse effects on the export potential of developing countries as a consequence. Further, the value of this support is capitalised in significant higher land prices in Europe than would otherwise prevail. The scenarios illustrate the economic implications of transforming all domestic support payments (as well as other distorting policies) into a nationally homogenous and fully decoupled payment to all agricultural land, irrespective of a farmer's decision to crop or not. The analysis suggests that it is possible to convert the existing agricultural support into a fully decoupled payment which would not distort international trade and it indicates a way forward to offset the negative impact on land prices. Such a policy would also comply with the WTO rules (i.e. fall within the green box as decoupled income support). The analysis also suggests that such a policy reform could be achieved at somewhat lower budgetary costs as compared with the existing costs of the Common Agricultural Policy.

Can China realise its energy-savings goal by adjusting its industrial structure?

To investigate whether China can realise its energy-savings goal by 2020 through adjustments to its industrial structure, this study proposes a dynamic input–output multi-objective optimisation model. According to this model, the objectives to be achieved include the maximum gross domestic product and employment, and the minimum energy consumption, where the constraints are the sectoral dynamic input–output balance, labour and energy supply, and sectoral production capacity. The four best solutions are screened from the Pareto-optimal front. The study findings show that the energy intensities in 2020 would decrease by 42.8%, 43.5%, 42.9%, and 43.4% in the four scenarios when compared to their 2002 levels. This means that China can fully achieve its planned energy-savings target for 2020. In order to ensure that the industrial structure is optimised for the future, sectoral capital investments should be regulated by China's government and efforts to improve energy efficiency should be maintained.

The adoption,diffusion, and evolution of organizational form: insights from the agrifood sector

The adoption and diffusion of contract farming and vertical integration in modern agriculture has varied widely across regions, commodities, or farm types. This paper lays out a framework for understanding the evolution of organizational practices in U.S. agriculture by drawing on theories of the diffusion of technology and organizational complementarities. Using recent trends as stylized facts, with case studies from various agricultural industries, we argue that research identifying complementarities within specific sectors of the agrifood system will greatly improve our understanding of the organizational structure of agricultural production, and we identify several specific lines of inquiry.

Influence measurement of rapid urbanization on agricultural production factors based on provincial panel data

The proportion of agricultural output value is continuously decreasing because of the process of rapid urbanization, but it is still the basis of economic development and urban construction. Agricultural production factors are at the core of agriculture, and have an important influence on the agricultural output value. In the period of rapid urbanization, high technical and capital investment improved agricultural production efficiency and increased the income of farmers. However, in recent years it also introduced serious problems for agricultural production, including aging farmers and weakening labor markets, farmland conversion, and soil pollution. In this study, we estimated the elasticity coefficients of agricultural production factors, including labor, capital and technique, using the improved Cobb–Douglas production function and provincial panel data from 2000 to 2015, and measured the effects of urbanization on elasticity coefficients using the Euclidean metric and gravity model. The results were as follows. (1) In time, the elasticity coefficient of labor was stable, and with a low increase from 0.238 to 0.304. However, the elasticity coefficients of land and capital had been increasing since 2000, by 1.125 and 0.140, respectively. The higher elasticity coefficient of agricultural production factors was gradual from labor to capital, with the growth of urbanization level. (2) In space, the elasticity coefficients were the space distribution, as urbanization divided into east, central and west: the elasticity coefficients of labor and land in the eastern regions were higher, and the elasticity coefficient of capital in the central regions was higher. (3) Economic urbanization had a larger positive influence on the elasticity coefficient of capital, and the population had a larger negative influence on elasticity coefficients of labor. The quantitative results were similar to the development status, but there were different influences on elasticity coefficients in different provinces. (4) Finally, the study put forward suggestions for agricultural sustainable development according to the function mechanism of urbanization on agricultural production factors, including increasing the attention paid agriculture, ensuring a stable market environment, and optimizing the industrial structure, with reference to scientific, green and healthy agriculture.     

Intersectoral efficiency between agriculture and industry in six C.M.E.A. countries: Introducing a simple equilibrium model

The purposes of this paper is to show how the long-run preferences for industry and agriculture of the planning bodies in six C.M.E.A. countries can be analyzed by using data on factor allocations in these sectors. Indicative results describing these preferences are obtained and existing inefficiencies in labor allocation and the relative domestic prices of industrial and agricultural goods are discussed. The conclusions suggest that the preferences of the planning bodies have stayed completely constant over 1950–1980 only in the case of the GDR, and that allocations of labor and domestic price ratios have mostly been far from optimal over that period in the countries that were analyzed.The author wishes to thank Prof. Paul Jones of the University of New Mexico Economics Department, Prof. R.

Regional and National Perspectives of China's Integration into the WTO: A CGE Inquiry with Emphasis on the Agricultural Sector

China's integration in the World Trade Organization (WTO) is already on its fast track. Understanding the complexity of China's dynamic adjustment resulting from its membership in the WTO and the differential regional impacts within China is very important and poses crucial challenge in evaluating its impacts. In this study, we make an attempt to incorporate seven regional commodity-detailed models into a dis-aggregated multi-sector and multi-region China Computable General Equilibrium (CGE) framework. This framework has allowed us to evaluate the impacts of China's integration into the WTO at both national and regional levels and analyze the inter-linkages between China's provincial agricultural markets. Using the framework and assumptions about factor mobility, we assess the impacts on China's agricultural and non-agricultural sectors (regionally and nationally) by reduction of its trade policy distortions, such as tariffs rate changes and quantitative restrictions. We also evaluate the structural changes on China's national and regional production and trade as China implements its commitments and moves into the WTO.     

Sources of Sectoral Growth in an Economy Wide Context: The Case of U.S. Agriculture

Growth in U.S. agriculture is linked to the non-farm economy through domestic terms of trade and factor market adjustments. With almost stable input growth, the relatively large contributions from growth in Total Factor Productivity (TFP) are passed on to intermediate and final consumers in the form of declining real prices for primary farm products. The resulting net growth in the real value of farm output (GDP) is relatively low (0.25% per annum). The decomposition of TFP suggests that public agricultural stock of knowledge and infrastructure are robustly associated with TFP growth, while spill-overs from private agricultural and economy wide research and development (R and D) are positive but, relatively small.     

The Exchange Rate and the Trade Balances of Turkish Agriculture,Manufacturing and Mining

This paper investigates and compares the response to the exchange rate changes of trade balances of three Turkish sectors; agriculture, manufacturing and mining. The impact on trade balance of exchange rate changes is examined using the trade balance model employed in Bahmani-Oskooee [1985, Review of Economics and Statistics 67: 500]. Analysis is conducted based on the quarterly data from 1986: I to 1998: III. It is observed that in response to domestic currency depreciation trade balance of each of all three sectors first improves, then deteriorates and then improves again. Despite exhibiting similar pattern of reaction to the exchange rate change in the short run, long-run or overall response of trade balance differs across the sectors; while trade balances of both manufacturing and mining improve in the long run, agricultural trade balance worsens as a result of domestic-currency depreciation.     

Productivity,efficiency and technical change: measuring the performance of China’s transforming agriculture

As China enters the twenty-first century the health of the agricultural economy will increasingly rely, not on the growth of inputs, but on the growth of total factor productivity (TFP). However, the tremendous changes in the sector—sometimes back and sometimes forwards—as well as evolving institutions make it difficult to gauge from casual observation if the sector is healthy or not. Research spending has waxed and waned. Policies to encourage the import of foreign technologies have been applied unevenly. Structural adjustment policies also triggered wrenching changes in the sector. Horticulture and livestock production has boomed; while the output of other crops, such as rice, wheat and soybeans, has stagnated or fallen. At a time when China’s millions of producers are faced with complex decisions, the extension system is crumbling and farmer professional associations remain in their infancy. In short, there are just as many reasons to be optimistic about the productivity trends in agriculture as to be pessimistic. In this paper, we pursue one overall goal: to better understand the productivity trends in China’s agricultural sector during the reform era—with an emphasis on the 1990–2004 period. To do so, we pursue three specific objectives. First, relying on the National Cost of Production Data Set—China’s most complete set of farm input and output data—we chart the input and output trends for 23 of China’s main farm commodities. Second, using a stochastic production frontier function approach we estimate the rate of change in TFP for each commodity. Finally, we decompose the changes in TFP into two components: changes in efficiency and changes in technical change. Our findings—especially after the early 1990s are remarkably consistent. China’s agricultural TFP has grown at a healthy rate for all 23 commodities. TFP growth for the staple commodities generally rose around 2% annually; TFP growth for most horticulture and livestock commodities was even higher (between 3 and 5%). Equally consistent, we find that most of the change is accounted for by technical change. The analysis is consistent with the conclusion that new technologies have pushed out the production functions, since technical change accounts for most of the rise in TFP. In the case of many of the commodities, however, the efficiency of producers—that is, the average distance of producers from the production frontier—has fallen. In other words, China’s TFP growth would have been even higher had the efficiency of production not eroded the gains of technical change. Although we do not pinpoint the source of rising inefficiency, the results are consistent with a story that there is considerable disequilibrium in the farm economy during this period of rapid structural change and farmers are getting little help in making these adjustments from the extension system.     

Agriculture and development: A brief review of the literature

After 20 years of neglect by international donors, agriculture is now again in the headlines because high food prices are increasing food insecurity and poverty. In the coming years, it will be essential to increase food productivity and production in developing countries, especially in Sub-Saharan Africa and with smallholders. This, however, requires finding viable solutions to a number of complex technical, institutional, and policy issues, including land markets, research on seeds and inputs, agricultural extension, credit, rural infrastructure, connection to markets, rural non-farm employment, trade policy and food price stabilization. This paper reviews what the economic literature has to say on these topics. It discusses in turn the role played by agriculture in the development process and the interactions between agriculture and other economic sectors, the determinants of the Green Revolution and the foundations of agricultural growth, issues of income diversification by farmers, approaches to rural development, and issues of international trade policy and food security, which have been at the root of the crisis in agricultural commodity volatility in recent years.     

An International Comparison of Leontief Input-Output Coefficients and its Application to Structural Growth Patterns

Empirical sectoral analyses of a standard development pattern have focused upon changes in the value added, disregarding the structural changes in intermediate input. In a more comprehensive approach to the production function, the present paper analyses both sectoral intermediate inputs and the value added by using 45 input-output tables to discover a standard pattern of the changes in the input-output coefficients as an economy develops. The major findings are first a U-shape pattern of the average value added ratio and, conversely, an inverse U-shape pattern of the average intermediate input ratio. Secondly, as compared with principal input coefficients that are broadly stable, supplementary input coefficients exhibit the non-linear trends of an inverse U shape contributed by a rising trend in agriculture in the early stages, and a growing energy cost in most sectors, although this is partly offset by mild U shapes of transport and distribution costs. A similar inverse U-shape pattern is implied for the Leontief multiplier.     

REGIONAL AGRICULTURAL PRODUCTION SYSTEMS: ESTIMATES FOR WESTERN AUSTRALIA

A regional model, be it computable general equilibrium or partial equilibrium in construct, which is based on the national parameters would certainly provide misleading results if the regional economy or sector is significantly different from its national counterpart. For a credible and useful quantitative analysis of the regional impacts of changes in, say, government policies or international events, one thus needs an empirically based economic model that reflects the key features of the regional economy or sector concerned. This is the motivation for this paper, which estimates a disaggregated agricultural production system for Western Australia (WA): a key farming State of Australia. The paper uses a profit function approach that explicitly recognizes jointness in agricultural production and various climatic zones in WA, and an estimation procedure that involves the Diewert–Wales decomposition technique. It presents estimates of elasticities of supply responses and input demands in WA agriculture, and compares these with the national estimates.
