Food Security and Agricultural Protection in South Korea

South Korea has been pursuing food self-sufficiency using high tariffs and high administrative prices in key agricultural and food markets. Using a dual approach to trade and trade restrictiveness indices, we analyze the impact of these market distortions on welfare and trade volume. Then, we compute second-best distortions, which minimize the welfare cost of meeting observed levels of self-sufficiency and production. We rationalize these second-best distortions to what could be claimed as legitimate protection under a "food security" (FS) box in World Trade Organization (WTO) negotiations. FS-box protection is sensitive to changes in the definition and the extent of the FS objectives. We show that FS via production targets and reliance on imports would be more palatable to consumers and trade partners, while preserving income transfer to the farm sector.     

Self-Sufficiency Versus Free Trade: The Case of Rice in Iran

The dilemma of free trade and self-sufficiency for the case of rice in Iran justifies continuous governmental intervention in this market. Among all policy instruments, import tariffs have been extensively used to achieve self-sufficiency; however, the results of this policy are quite controversial and remain as a main question for researchers and policymakers. Hence, this article examines the economic impacts of increasing import tariff policy applying a multimarket spatial price equilibrium model. The results suggest that pursuing the goal of self- sufficiency by restricting rice import would be detrimental. Social welfare as well as real and per capita income are adversely affected by increasing import tariffs both in nationwide and regional scale except for 1 region, which is characterized as the largest net exporter region in Iran. Also results show that adopting free trade policies and improving rice yield may be the well-advised strategy in the case of rice in Iran.     

Welfare effects of maize technologies in marginal and high potential regions of Kenya

This paper describes the findings of a study that used a multi‐market model to assess the potential impact of improved maize technologies on the welfare of various types of rural and urban households in Kenya. The modelling results indicate that technologies developed for high potential regions are likely to have more profound aggregate impacts on maize production and lead to greater reductions in import demand (if prices are controlled) or maize prices (if maize prices are flexible). Technology adoption in high potential regions is likely to have substantially greater positive impacts on aggregate real incomes, but inferior income distributional outcomes compared to technology adoption in marginal regions.     

The effects of NCPB marketing policies on maize market prices in Kenya

The Government of Kenya pursues maize marketing policy objectives through the National Cereals and Produce Board (NCPB), which procures and sells maize at administratively determined prices, and stores maize as a contingency against future shortages. A private sector marketing channel competes with the NCPB. This article estimates the effects of NCPB activities on the historical path of private sector prices in Kenyan maize markets between 1989 and 2004. The analysis is carried out using a reduced form vector autoregression model (VAR) estimated with sparse data and imposing only minimal identification restrictions. Results show that NCPB activities have stabilized maize market prices in Kenya, reduced price levels in the early 1990s, and raised average price levels by roughly 20% between 1995 and 2004. Over the past decade, the price-raising activities of the NCPB have transferred income from urban consumers and a majority of small-scale farm households that are net buyers of maize to a relatively small number of large- and small-scale farmers who are sellers of maize.     

Impact of Environmental Policies in the Hog-Pork Sector on Trade and Market Welfare in North America

The objective of this study is to design a framework to assess trade patterns and market welfare (Marshallian measures of producer and consumer surpluses plus government payments) under various combinations of agricultural, environmental and trade policies. To reach this objective, an environmental model, EPIC, is linked to a model of the North American hog-pork sector. The reduction in Québec inventories, following the implementation of environmental policies, triggers a decrease of Canadian live hog exports to the U.S. and an increase of U.S. pork exports to Canada. Environmental policies are responsible for decreases in welfare. The decrease in welfare is the largest when a moratorium in North America is simulated. Since trade liberalization has a positive impact on welfare, the welfare decrease from a moratorium is somewhat attenuated under free trade conditions.     

Measuring producer welfare under output price uncertainty and risk non-neutrality

Procedures to measure the producer welfare effects of changes in an output price distribution under uncertainty are reviewed. Theory and numerical integration methods are combined to show how for any form of Marshallian risk-responsive supply, compensating variation of a change in higher moments of an output price distribution can be derived numerically. The numerical procedure enables measurement of producer welfare effects in the many circumstances in which risk and uncertainty are important elements. The practical ease and potential usefulness of the procedure is illustrated by measuring the producer welfare effects of USA rice policy.     

Enhancing food security in South Sudan: the role of markets and regional trade

South Sudan faces serious problems of food insecurity due to low levels of domestic food production, periodic droughts, widespread poverty, and since late 2013, renewed armed conflict. This article explores market price behavior using cointegration analysis and estimates the effects of production and trade shocks through multimarket model simulations. We show that market prices in the capital city, Juba, of both maize and sorghum are cointegrated with import parity prices of these cereals sourced from Uganda, consistent with observed trade flows. Model simulations, using econometrically estimated demand parameters, suggest that private sector imports of maize and wheat would greatly mitigate the potential fall in consumption in the case of a decline in domestic cereal production. Other simulations indicate that if total imports of cereals are reduced by one‐third (still more than two times the levels of food aid in 2013) because of disruptions to private market flows, domestic prices of cereals could rise by 45% or more. The article concludes that whatever measures are taken involving national food security reserves, it is crucial that government policy serves to maintain incentives for private sector imports to avoid destabilizing market supplies, domestic prices, and ultimately, food consumption of the poor.     

Trade Liberalization,Policy Reform and the U.S. Sugar Industry

This study examines the prospects for and potential impacts of liberalized international trade in sugar. It utilizes a state specific, cost of production based estimate of U.S. sugar supply to examine producer surplus under the current sugar policy regime and under a free trade scenario. It also evaluates the long-term viability of sugar production in individual states at free market prices.     

Meat and milk self-sufficiency in Asia: forecast trends and implications

Recent structural changes in dietary patterns in Asia resulting from economic development are placing increasing pressure on the existing production systems in the region-particularly those systems producing ruminant meat, non-ruminant meat and milk. This has significant policy implications for the countries in the region in terms of self-sufficiency goals in these commodities and the associated inter-and intra-regional trade opportunities in the future. Forecasts of ruminant meat, non-ruminant meat and milk production and consumption for selected Asian countries between the years 2000 and 2010 revealed the following: China, Pakistan and Viet Nam are likely to be self-sufficient with respect to ruminant meat; Malaysia is likely to continue to be a net importer of ruminant meat; India and Malaysia will be more than self-sufficient with respect to non-runvinant meat with the converse being true for Pakistan; and India, Laos and Pakistan will be self-sufficient with respect to milk production with the possibility of Indonesia, Thailand and Cambodia becoming self-sufficient if the current trends continue. Structural changes in the early 1980s generally resulted in higher average annual growth rates of production-particularly in non-ruminant meat production. Thus forecasts of ruminant meat production and consumption by 2000 using the medium-term average annual growth rates for production present a more favourable outcome in terms of self-sufficiency for countries such as Bangladesh, the Philippines and Viet Nam but a less favourable outcome for countries such as Indonesia, Malaysia, Laos and India. Similar forecasts for non-ruminant meat indicated an improvement in the long-term non-ruminant self-sufficiency estimates for most cases-particularly for Bangladesh, China and Cambodia. Intensification and commercialisation of meat production systems have increased meat self-sufficiency in a number of countries but often at the expense of grain self-sufficiency. Given these trends, the impact of trade liberalisation measures on livestock production in the region and inter-and intra-regional trade of livestock commodities and grain is likely to be significant.

Economic welfare analysis of policy-induced structural change in the Indonesian poultry industry

The performance of the poultry industry in Indonesia is analyzed in terms of changes in producer and consumer welfare as a result of public policy intended to limit the size of production units in order to distribute growth opportunities to smallet farms. Elasticities of supply and demand are estimated using the seemingly unrelated system of equations. The hypothesis of a policy-induced structural change, estimated through a dummy variable accounting for a shift in supply associated with implementation of the policy, shows a negative impact on the output supplied and the welfare of producers and consumers to the tune of about Rp 94 billion or roughly about 0.1% of national income as of 1983. The study suggests an important trade-off between more equitable income distribution and economic efficiency.     

Trade liberalisation and greenhouse gas emissions: the case of dairying in the European Union and New Zealand*

The link between trade and the environment has aroused considerable interest both in terms of the impact of trade liberalisation on the environment, and also the impact of environmental policy on production and trade. Of key environmental concern at present is global warming and its association with greenhouse gas emissions. Agriculture is a sector of the economy that both contributes to, and will be affected by, climate change. This paper models the impact of agricultural trade liberalisation on greenhouse gas emissions from agriculture around the world, focusing particularly on the effects on New Zealand, a small economy highly dependent on agricultural trade. A partial equilibrium agricultural multicountry, multicommodity trade model is used for the analysis, extended to include physical production systems and their greenhouse gas emissions. Two simulations are performed: removal of agricultural policies in the EU and in all OECD countries. The results indicate that although producer returns in New Zealand increase, greenhouse gas emissions also increase significantly. EU producers face lower returns but also lower greenhouse gas emissions.     

Social welfare effects of removing multiple exchange rates: evidence from the rice trade in Iran

In order to encourage the involvement of the private sector in importing rice, the Iranian government plans to relax the system of multiple foreign exchange rates applied to importers wishing to supply the domestic market. In this article, the welfare effects of removing the current controls on the rice trade, and a domestic rice coupon program, are evaluated by applying a partial equilibrium analysis to 1961–1999 data. The results show that, as far as foreign exchange is concerned, liberalization of the rice market causes an increase in rice imports, mainly due to a decrease in domestic supply. In welfare terms, the loss in producer surplus from rice market liberalization is relatively high, but most rice consumers, and the Iranian taxpayer, would gain. Overall, gains to consumers and taxpayers are estimated to be higher than the losses incurred by domestic suppliers, and therefore net social welfare at national level can be improved by rice market liberalization in Iran. Issues for further discussion include residual food security roles for the state, and supply‐side adjustments in terms of resource use and higher‐quality production.     

Brexit: How Will UK Agriculture Fare?

There is little doubt that Brexit would have significant implications for UK agriculture, a sector with strong trade links to the EU and strong reliance on CAP income support. This article reports preliminary results from employing a Computable General Equilibrium Model, a Partial Equilibrium Model and Farm Level Models to explore selected trade and domestic policy scenarios post‐Brexit. These allow for the estimation of changes in producer prices, production and farm incomes against a baseline scenario of continued EU membership. Under a Free Trade Agreement with the EU, agricultural impacts are relatively modest. By contrast, unilateral removal of import tariffs has significant negative impacts on prices, production and incomes. Adoption of the EU's WTO tariff schedule for all imports favours net importers (e.g. dairy) and harms net exporters (e.g. sheep). Given the strong dependence of most UK farms on direct payments, their removal worsens negative impacts of new trade arrangements and offsets positive impacts. Impacts vary across different types and sizes of farm, but also regionally. However, the period of adjustment to new trade and domestic policy conditions may prove very challenging for a large number of farm businesses.     

Economic Meltdown in Malaysia

Abstract

The economic downturn in Malaysia has encouraged a debate on the benefits of its export-oriented industrialisation strategy. There is renewed interest in the agricultural and livestock sectors. One of the beneficiaries of this policy change could be the dairy farming sector. Using desktop research and ‘key-informant’ techniques, this study reviews various factors that could influence the development of the dairy farming sector in Malaysia. The study concludes that the (a) Government may encourage the start-up of integrated plantation crop, animal feed and livestock farms, (b) investment and trade linkages with neighbouring countries could lead to diversification of import sources, and (c) consumption of dairy products may have matured, leading to increases in dairy self-sufficiency. It is postulated that these developments will produce a dynamic environment and significant threats to the interests of traditional dairy exporting countries.     

THE INFLUENCE OF THE AGRI-MONETARY SYSTEM ON AGRICULTURAL TRADE IN THE EC: THE CASE OF SUGAR

It is hypothesised that the mechanics of the agri-monetary system impose shocks on EC agricultural markets which influence the Community's agricultural trade flows. A model illustrating links between agri-monetary changes and trade flows of sugar is presented. Empirical tests suggest that agri-monetary changes influence the volume and timing of sugar trade. Hypotheses relating the strength of this influence to self-sufficiency and other factors specific to Member States are discussed, as are the welfare costs of agri-monetary trade distortions. Although these welfare costs are unlikely to spark agrimonetary reform, they could be given consideration in the reform made inevitable by the Single European Market.     

Trade Liberalization,State Trader Management Tenure,and Grain Pricing in Botswana

This article examines how trade liberalization and grain marketing board management tenure influenced grain pricing in Botswana. Regression analyses of nominal protection rates (NPRs) and marketing margins (MMs) are used to test the hypothesis that policy reforms influenced grain pricing in the country. Moreover, a comparison of NPRs is undertaken to determine whether management tenure has had an influence on grain pricing. The results indicate that the marketing board switched from taxing to subsidizing consumers following the 1991 policy reform from food self-sufficiency to food security. A reversal occurred after the board's 1997 restructuring, which involved, among other things, closing down Botswana Agricultural Marketing Board's (BAMB's) loss-making units and a change in the composition of BAMB's board of directors. Management tenure at BAMB also had an influence on grain pricing. The period 1989–1997, in particular, was characterized by high consumer subsidization, highest marketing margins, and lowest profits. This could have been avoided had management adopted pricing regime consistent with public policy. This notwithstanding, perennial losses experienced by the marketing board also resulted from fragmented production and low producer market participation.     

Potential impact of a Transatlantic Trade and Investment Partnership on the global forest sector

The effects of a transatlantic trade agreement on the global forest sector were assessed with the Global Forest Products Model, conditional on previous macroeconomic impacts predicted with a general equilibrium model. Comprehensive tariff elimination per se had little effect on the forest sector. However, with deeper reforms and integration consumption would increase twice as much in percent in the US as in the EU. Net trade decreased in the US more than in the EU while it increased in Asia. Consumers and producers’ welfare increased by $7000 million in the EU and $14,000 million in the US, but decreased in some third countries, especially in Asia.     

Impacts of trade liberalization in Canada's supply managed dairy industry

Trade is an integral part of the Canadian economy. The main institutional drivers governing trade are bilateral and multilateral agreements outlining permissible trade distorting measures. Since its inception in 1972, Canada's supply management system has remained protected throughout trade negotiations. The system appears, by any economic measure, to be having an increasingly disproportional influence in recent trade negotiations. However, trade agreements serve not only to maximize social surplus, but also to maximize some measure of political welfare. Canada has recently negotiated three prominent trade agreements: the Canada-European Union Comprehensive Economic and Trade Agreement (CETA) came into effect in the latter part of 2017; the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) came into effect at the end of 2018; and the Canada-United States-Mexico Agreement (CUSMA) could come into effect in 2020. Collectively, these agreements have guaranteed increased market access for fresh and processed dairy products. We build a spatial partial equilibrium model of the Canadian dairy industry consisting of three regions and 10 commodities to assess the individual and cumulative effect of these trade agreements. We pay particular attention to the institutional drivers within today's dairy sector: milk protein isolates; component pricing, including Class 7; and differential demand growth. We find that the aggregate impacts are: (a) a 1.4% decrease in the marginal retail price; (b) a 4.8% decrease in the blended producer price; and (c) an overall increase in social welfare of 7.8%. Worth noting, the decrease in producer surplus varies from 0.7% in the western region to 1.5% in Ontario. Our results may be relevant to future negotiations as well as the publicly promised compensation package for dairy producers.     

Measuring Heterogeneous Preferences for Cattle Traits among Cattle-Keeping Households in East Africa

This study employs mixed logit and latent class models to examine preferences for cattle traits with a focus on heterogeneity among cattle keepers, using choice experiment data of 506 cattle-keeping households in Kenya and Ethiopia. The findings indicate the existence of preference heterogeneity based on cattle production systems. Highly valued cattle traits for the cropping systems include traction fitness and trypanotolerance, while traits associated with herd increase are considered important in pastoral systems. Considering heterogeneity within population segments provides a framework for adapting breeding policy interventions to specific producer segments, by integrating preferred traits in a breed improvement program.
