In the EU dairy sector, given the remaining high protective tariffs and the quota system, the main factor that drives dairy product market prices is the demand. This paper evaluates the development of demand in the EU and presents estimates of consumption trends and forecasts for the future as well as estimates of elasticity with respect to prices and income in two major EU consumer countries: France and Italy. We use two methods to estimate the development of demand for dairy products, one based on a multi-stage demand system and another based on a single trend equation. The two methods generally lead to the same qualitative results but trend projections are larger using the demand system approach which is based on a shorter data period. This difference is thus partly explained by the fact that high trend projections are not sustainable over a long period. The results show a decreasing consumption of butter and fluid milk and an overall growth in protein and fat consumption. Nevertheless, the increase in fat consumption should be more moderate than the consumption of protein. The results also show that the demand for dairy products is relatively price inelastic but is more sensitive to changes in income (especially for butter and cheese categories). As shown by the use of a partial equilibrium model of dairy markets, the likely impact of the CAP reform strongly depends on the development of demand for dairy products in the EU. More research effort on demand analysis is therefore crucial in order to assess the impact of reforms or trade negotiations more accurately and effectively.  相似文献

This paper takes a local perspective on global food price shocks by analyzing food price transmission between regional markets in Ghana. It also assesses the impacts of food price increases on various household groups. Taking the 2007–2008 global food crisis as an example, we show that prices for domestic grain products are highly correlated with world market prices. This is true both for products for which Ghana is highly import-dependent (e.g., rice) and the products for which Ghana is self-sufficient (e.g., maize). The econometric results also show that price transmission is high between regional producer markets and markets located in the country’s largest cities, and the distance between producer and consumer markets and the size of consumer markets matter in explaining the price transmission. The welfare analysis for households as consumers shows that the effect of world food prices appears relatively modest for the country as a whole due to relatively diverse consumption patterns within country. However, the national average hides important regional differences, both between regions and within different income groups. We find that the poorest of the poor—particularly those living in the urban areas—are hardest hit by high food prices. The negative effect of the food crisis is particularly strong in northern Ghana. The main explanations for this regional variation in the price effect is the different consumption patterns and much lower per capita income levels in the North of Ghana compared to other regions in the country.  相似文献

This paper develops an economic analysis of the impacts of further trade liberalization scenarios on Asian dairy markets, using a world dairy model incorporating both vertical and spatial characteristics of the world dairy sector. Japan and Korea’ producers will suffer much bigger losses from trade liberalization than other countries in the region; Japan and Korea’s producers get much more protection from trade distortions than from domestic subsidy. India is a potential competitive exporter if Asia is liberalized. China and India are potential competitive exporters under global free trade. South East Asia and other South Asian countries remain importers under free trade. Greater trade liberalization around the world increases exports for potential exporters and/or ease importing pressure for potential importers. The increasing order of competitiveness of Asian dairy economies sectors is found to be Japan, Korea, South East Asia, other South Asia, China and India. China and India consumers would lose from world trade liberalization, but the other countries’ consumer surplus will increase.  相似文献

Crop yields are endogenous as long as economic agents adjust to permanent changes in expected prices. The literature, however, does not offer a definitive value of how much yield would change in response to sustained price changes. To fill the gap, we use available scientific findings and data to estimate yield elasticities that enable agricultural commodity and food policy analysis. Using a world market model with short- to long-run yield response, we show the impacts of sustained energy price shocks on global cereal supply and demand. The results highlight substantial differences in quantity and price effects depending on the yield elasticities. These results demonstrate the need to recognize yield response when assessing impacts of energy prices or biofuel production on food uses or, more generally, on food security in the face of income and population growth, evolving dietary patterns, climate change implications, or other long-run pressures.  相似文献

Faced with high domestic rice prices that have fueled inflation above the 2018 target and penalized poor consumers the most, the government of the Philippines has decided to abandon the quantitative restrictions on imports and replace them with tariffs. This paper uses a global rice model based on a partial equilibrium framework to assess the possible impacts of this reform on imports, production, consumption and prices. In contrast with past similar studies, we address three key concerns (i) the heterogeneity in farm price across 16 regions in response to the combined effect of the tarriffication and the average historical trend in productivity increase at 1.5% between 2001 and 2018, (ii) the differentiation of imports by origin partly due to the different tariffs applied to countries within and beyond the Association of South East Asian Nations, and (iii) the effect on domestic prices in third countries. The simulation results suggest that the reform would increase imports by 2.47 million tons (20.7%) in 2019. We also find a large decline in farm prices and retail prices respectively by PhP 6.1/kg (30.1%) and PhP 7.6/kg (17.4%) in 2019 that explains an increase in rice consumption. We estimate the fall in total inflation at 1.2% in 2019 but less over time. Further, the large fall in farm prices in 2019 is shared quite evenly among regions in the short term but returns to pre-reform levels in the near term. Using a higher price elasticity of supply for one region obtained from panel data surveys, we show a more pronounced decline in production than the national average. Such differentiated results confirm the relevance of using a regionally disaggregated model to design more targeted policies. We also show a slight increase in world prices, which led to small increases in the domestic prices of South and Southeast Asian rice markets. While this reform is largely pro-poor consumers, policy makers would need to use the additional tariff revenue to help rice growers either increase their competitiveness and modernize their rice production or shift to other crops.  相似文献

The rapid expansion of biofuel production has generated considerable interest within the body of empirical economic literature that has sought to understand the impact of biofuel growth on the global food economy. While the consensus within the literature is that biofuel emergence is likely to have some effect on future world agricultural market, there is a considerable range in the estimated size of the impact. Despite the importance of this topic to policy makers, there has been no study that has tried to reconcile the differences among various outlook studies. This paper undertakes an in-depth review of some key outlook studies which quantify the impacts of biofuels on agricultural commodities, and which are based on either general-equilibrium (GE) or partial-equilibrium (PE) modeling approaches. We attempt to reconcile the systematic differences in the estimated impacts of biofuel production growth on the prospective prices and production of three major feedstock commodities, maize, sugar cane, and oilseeds across these studies. Despite the fact that all models predict positive impacts on prices and production, there are large differences among the studies. Our findings point to a number of key assumptions and structural differences that seem to jointly drive the variations we observe, across these studies. The differences among the PE models are mainly due to differences in the design of scenarios, the presence or absence of biofuel trade, and the structural way in which agricultural and energy market linkages are modeled. The differences among the GE models are likely to be driven by model assumptions on agricultural land supply, the inclusion of the byproducts, and assumptions on crude oil prices and the elasticity of substitution between petroleum and biofuels.  相似文献

International trade agreements are pushing the world in the direction of free trade. But price stabilization, which is inconsistent with completely free trade, remains important in developing Asia because of the large share of rice in economic output. A policy of pure price stabilization for rice, without consistent protection (either subsidization or taxation), can help to create the macroeconomic stability that is essential for sustained rapid economic growth by increasing the quantity and efficiency of investment throughout the economy. Pure price stabilization can also generate significant equity gains by protecting poor consumers and farmers from sharp fluctuations in prices. While domestic commodity price stabilization schemes have a checkered history around the world, the experience of Asian countries in stabilizing rice prices offers more scope for optimism. Asian governments have been generally successful in stabilizing rice prices, and there are several instances where this has been accomplished without sustained protection of either consumers or farmers. However, there is room for improved stabilization mechanisms that would lower the costs of intervention.  相似文献

Rapid economic and income growth, urbanization, and globalization are leading to a dramatic shift of Asian diets away from staples and increasingly towards livestock and dairy products, vegetables and fruit, and fats and oils. While the diversification of diets away from the traditional dominance of rice with rising incomes is expected and observed, current food consumption patterns are showing signs of convergence towards a Western diet. The diet transition is characterized by increased consumption of: wheat; temperate fruit and vegetables and high protein and energy dense food. Globalization and the consequent global interconnectedness of the urban middle class, is the driving force behind the convergence of diets. The rapid spread of global supermarket chains and fast food restaurants is reinforcing the above trends.  相似文献

Got milk? The rapid rise of China’s dairy sector and its future prospects   总被引:1,自引:0,他引:1  
This paper synthesizes recent research and new empirical findings to build a more comprehensive understanding of developments in China’s dairy sector. China’s tremendous rise in dairy demand has been driven by several mutually reinforcing factors: including rapid income growth, promotion by the government and dairy industry, changes in urban lifestyles, and the development of new, more sophisticated marketing channels. Domestic milk output has grown to satisfy rising demand largely by increasing the dairy herd. Substantial increases in productivity have been achieved through technology adoption, but there is evidence that the torrid growth has created inefficiencies because adaptations to marketing rules, infrastructure, and institutions have not kept pace with the changing environment. These results suggest there is ample room for future growth in both domestic milk production and dairy demand, but multinational firms and imported products will likely play and increasing role as China’s dairy market continues to develop.  相似文献

Evolving dairy markets in Asia: Recent findings and implications   总被引:1,自引:0,他引:1  
This paper is an overview of important findings regarding the ongoing evolution of Asian dairy markets based on a series of new economic investigations. These investigations provide systematic empirical foundations to assess Asian dairy markets with their new consumption patterns, changing industries, and trade prospects under different domestic and trade policy regimes, with four case studies (China, India, Japan, and Korea), a prospective analysis of future regional patterns of consumption, and a policy analysis of trade liberalization of Asian dairy markets. The overview distills the findings of these new investigations and integrates them in the earlier economic literature; it draws policy implications, and identifies lessons for countries outside of Asia, especially for emerging exporters in Latin America.  相似文献

There is a widespread belief that consumer coffee prices are high relative to bean prices and that lower consumer prices would lead to substantial increases in bean exports from Third-World countries. This issue is evaluated by analysing how retail prices, preferences and market power influence coffee demand in Sweden. A demand function is estimated for the period 1968–2002 and used, together with information on import prices of coffee beans, to simulate an oligopoly model. This approach gives estimates of the maximum average degree of market power and shows how coffee demand would react to reductions in marginal cost to its minimum level. The maximum level of market power is found to be low, but it generates large spreads between consumer and bean prices because the price elasticity has low absolute values. Moreover, the impact of a price decrease would be small because long-run coffee demand is dominated by changes in the population structure in combination with different preferences across age groups. Hence, a change to perfect competition would only have a negligible effect on bean imports.  相似文献

Due to increasing crude oil consumption, especially of the fast growing Asian economies, decreasing production rates of several oil fields and increasing exploration costs, the oil price reached a new all time high in July 2008. The present world wide economic crisis caused a sharp decrease of the oil prices, nevertheless, prices will rise again with economic recovery. In this paper, long term projections of the International Energy Agency (IEA) and future contracts notations are employed to estimate oil price development until the year 2020. We estimate the price transmission of crude oil prices to Austrian retail diesel and gasoline prices and combine the estimation results with long term projections of the crude oil price. These projections are used to analyze the effect of rising oil prices on Austrian railway demand. The effect of increasing mineral oil taxes with the aim of an increasing internalisation of the external costs of road traffic on railway demand is discussed.  相似文献

尽管再生资源在工业生产中替代原生资源的比例逐渐升高,但对再生资源价格波动的特征及对经济的影响尚缺乏研究。本文以再生铜为例,采用GRACH族模型分析发现,我国再生铜价格的波动存在一定集聚性和持续性,价格波动比较缓慢。且负向冲击对再生铜价格波动的影响比正向冲击大,存在显著的杠杆效应。此外,再生铜价波动具有显著的GARCH-M效应,即预期的风险对再生铜价格波动具有正向影响。然后采用VAR模型和脉冲响应函数等方法,引入产出、投资、消费和通货膨胀率变动等宏观经济变量,定量分析了再生资源价格波动与中国经济之间的关系。检验结果表明:再生铜价作为建筑业重要的生产资料,其价格上涨短期内 促使GDP增长,但长期则抑制投资,最终可能影响GDP增长并提高通货膨胀率,即再生铜价格上涨对国家经济发展有不利影响。本文的实证结果揭示出,对中国经济的影响而言,废旧金属价格的变动只是某种表象,经济增长和通货膨胀率变动的背后是更为复杂的原因,问题的实质是以固定投资拉动经济增长的发展模式和部分地区对房地产业过度依赖的产业结构的变化等对中国经济产生的根本性的影响。  相似文献

The telecommunication sector in Mexico was highly concentrated until 2013. The sector was mostly composed by a dominant player, a rationed market (low density of services), a poor institutional design, high tariffs, and weak regulation agents. The Herfindahl-Hirschman (HHI) index was 5333 for mobile telephone and 7,029 for fixed telephone services—among the highest scores in the world. In order to promote competition in the sector, Congress approved a reform in 2013 to establish a new regulator empowered to impose asymmetrical rules in the case of the predominance of a single firm. A declaration of preponderance of the dominant player was issued, promoting free interconnection rates and the mandatory sharing of its passive and active infrastructure with the rest of the firms in the industry. The new institutional design led to increased competition in the sector, decreasing the mobile and fixed telephone prices while increasing the coverage and penetration of these services. In this article, an applied general equilibrium model for the Mexican economy is employed to assess the impact of the Telecommunication Reform in Mexico in the telephone sector, consumer welfare, and income distribution. The model is static, encompassing 10 types of consumers (rural and urban and the five income quintiles) and 40 sectors (of which four are disaggregate telecommunications industries). It assumes fixed wages and capital rental prices as well as idle resources. The main results indicate that the effects of the reform are not minor; the drop in telephone prices would reduce the general consumer price index by almost 2%, and the value added would increase by more than 3%, benefiting mainly households in the highest income quantiles.  相似文献

India has become the world’s largest milk producer but its dairy industry lacks market access. This paper determines how world dairy policy reforms would affect dairy production and trade in India and the competitiveness of its dairy industry. We measure nominal protection coefficient for India’s dairy products to determine level and change in competitiveness between 1975 and 2001. We estimate parameters of domestic demand for and supply of raw milk and whole milk powder to determine how a world price increase would affect domestic milk production and whole milk powder exports. Results show that India’s dairy products lack export competitiveness. But with less distorted world dairy markets, India could be competitive and would emerge as a net exporter of whole milk powder, benefiting dairy industries and milk producers in India.  相似文献

The 2006-2008 food price spike raised concerns about the impact of high commodity prices on poverty in developing countries. This paper addresses these concerns in relation to Uruguay, a small country that exports agricultural commodities and imports fuels. Applying a general equilibrium model, we find that, as a whole, an increase in commodity prices has a positive effect on the economy of Uruguay. Benefits obtained through a growth in export activities are partially outweighed by an increase in crude oil prices. In this context, extreme poverty increases. As in other countries, the increase in food prices affects the already poor population, who become even poorer. This fact highlights the need for policies that mitigate the negative effects of price shocks.  相似文献

This study summarizes the major changes over the period 1960–86 in the shares of world markets of the world'S leading American, European and Asian corporations based in 15 major industries. It relates the differential sales growth rates of the gaining and losing firms to national trends in industrial competitiveness, to employment change and to long-term returns to shareholders. One principal determinant of firms' global growth rates, and thence gains and losses in ‘world market share’, corporate research and development (R&D) intensity, is examined and tested on an 83-firm, six-industry subset of the overall data base. The proportion of corporate sales revenues allocated to commercially oriented R&D emerges as a, perhaps the, principal indicator of subsequent sales growth performance relative to competition over 5–10-year periods. Insofar as many U.S. and U.K. firms have lost global market share relative to Asian and European competitors over the past two decades, a significant contributory factor would appear to have been negligence on the part of many U.S. and U.K. firms of investment in technology as a factor determining strategic, competitive advantage.  相似文献

This paper compares the income of those office properties that are included in the FRC index, with the appraised values that are used to determine the index's appreciation component. We find that the appraised value of the portfolio was a constant multiple of its current income, over the 1978–1988 period. This seems at odds with what modern valuation theory would suggest, since both nominal interest rates and several measures of real rates varied widely over the sample. An alternate interpretation of our results is that the appraised values were based on a set of expectations about future income growth, that turned out over the period, to be continually at odds with respect to actual income.  相似文献
