Prevalence and infection intensity of the ovarian parasite Marteilioides chungmuensis during an annual reproductive cycle of the oyster Crassostrea gigas
Provedor de dados: 5
Autores: Ngo, Thao; Berthe, Franck; Choi, Kwang-sik.
The occurrence of Marteilioides chungmuensis, a protozoan paramyxean parasite in the reproductive system of the Pacific oyster Crassostrea gigas, was observed at Gosung Bay, Korea. Seasonal variation in gonad development was investigated in a suspended cultured oyster population. Gametogenesis began in February and first-spawning was observed between mid and late June when surface water temperature reached 22 to 25degreesC. Spawning activity extended from mid June to late September, with 2 marked spawning peaks in June and August. Histological examination indicated that gonad development paralleled seasonal fluctuations in water temperature. Spawning in late June was partly associated with a sudden drop in salinity due to large freshwater inputs to the Bay...

Implications of the U.S.-Korea Free Trade Agreement for Agriculture and other Sectors of the Economy
Provedor de dados: 31
Autores: Zhuang,   Renan; Mattson,   Jeremy W.; Koo,   Won W.
This paper examines the effects of the U.S.-Korea free trade agreement (KORUS FTA) on various sectors of the economy in the two countries using a general equilibrium model. Additional analysis focuses on the agricultural sector.  Our analysis indicates that the increase in U.S.-Korea bilateral trade volume in recent years has been through intra-industry trade of high-technology products.  Under the KORUS FTA, the bilateral trade volume would increase for virtually all the sectors, and GDP and social welfare would improve for both countries.  However, producers of textile products in the United States and producers of agricultural and food products in South Korea would suffer from the FTA.  This agreement could benefit U.S. agriculture, but the benefits...

The Cost of Food Self-Sufficiency and Agricultural Protection in South Korea
Provedor de dados: 31
Autores: Beghin,   John C.; Bureau,   Jean-Christophe; Park,   Sung Joon.
As part of its food security policy, 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 optimum distortions, which minimize the welfare cost of observed self-sufficiency and production objectives. We rationalize these optimum distortions to what could be claimed as legitimate protection under a "food security" (FS) box in World Trade Organization 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...

Impact of Direct Income Payments on Productive Efficiency of Korean Rice Farms
Provedor de dados: 31
Autores: Kang,   Hye-Jung; Kim,   Jeong-Ho.
This paper examines the impact of direct income payments on productive efficiency of Korean rice farms, using farm-level cross sectional data in 2006. For representation of efficiency and its determinants, this paper uses a model that estimates the deviations of farms from a translog distance function and the determinants of these deviations. This paper especially estimates a stochastic frontier production function to explain deviations from best-practice productivity with a two-part error term including statistical noise from measurement error and technical inefficiency arising from farms not reaching the production frontier boundary. The empirical evidence finds that farms that get a higher share of direct payments in farm revenue are less efficient than...

Transition to Decoupled Rice Support and Its Production Effects in Korea
Provedor de dados: 31
Autores: Lim,   Song-Soo.
Abolishing a nearly 50-year-old policy for rice price support, Korea adopted a new direct payment program in 2005. Making the transition to decoupled income support has been governed by the need for operative and effective income safety nets and the WTO disciplines on domestic support. The program aims to deal with over-supply of rice while guarding against the threat of income insecurity. Integrated into a target price mechanism, the fixed and variable payments compensate part of farm income loss arising from adverse market conditions. An empirical estimation based on the farm-level data is performed to test the degree of a linkage between rice support and production. The analysis suggests that rice support have only marginal influence on production with...

Impacts of the Doha Round on Korea's Agricultural Tariff Profile
Provedor de dados: 31
Autores: Lim,   Song-Soo.
The purpose of this paper is to simulate the proposed modality in market access and estimate its potential impacts on Korea's tariff profile. By accommodating a tiered formula for tariff reduction, the modality attempts to harmonize tariffs across products and countries. When no flexibility in tariff cuts is taken into account, Korea would face up to 68 percent reduction in tariffs in an average term (the baseline). The provision of sensitive products in which the tariff cuts are allowed to deviate from the tiered formula by two-thirds at a maximum is likely to bring about 11 percentage points of maximum tariff saving effects compared with the baseline case. Besides, Korea would be able to maximize savings in tariff reductions by 25 percentage points by...

Economic Analysis of the Liberalization of Red Meat Markets in the Pacific Region from 1988 to 2007
Provedor de dados: 31
Autores: Charlebois,   Pierre; Gagne,   Stephan; Gendron,   Carole.
The liberalization of red meat (beef and pork) markets since 1988 is a good example of government action that has led to significant gains for the Canadian and American agri-food industries. Japan, South Korea and Mexico are the main countries that have liberalized their red meat markets since 1988. This industry has also benefited from the agreement between Canada and the United States. It has also made gain from the liberalization of the pork market in Australia and the Philippines, and the beef market in Indonesia.  This analysis captures the impact on the price received by farmers as well as on Canadian production in the absence of these increased market access. The combination of lower prices and lower production would have caused annual average...

Agricultural Policy Adjustments in East Asia: The Korean Rice Economy
Provedor de dados: 31
Autores: Kwon,   Yong Dae; Yamauchi,   Hiroshi.
The processes of agricultural policy decision-making in the East Asian economies of Japan, Taiwan, and Korea are characterized by the complex interactions of competing special interest groups in their respective political arenas. An analytical model is designed to investigate how adjustments in rice price policies are endogenously related to the political economic forces associated with macroeconomic changes. The model is tested against the case of Korean rice price policy, which has not been satisfactorily explained in earlier modeling efforts. A political preference function is used to estimate the relative political weights of producers, consumers, and government over a 25-year period (1961-1985) during which major macroeconomic changes occurred. A...

Autores: Kim,   Sounghun.
The Ministry of National Defense (MND) is the biggest governmental consumer in the Korean agro-food sector. In 2006, the quantity of purchased agricultural products was about 260 thousand tons and the MND spent about 300 billion won for this purchase. The purpose of this paper is to review the current status of the food purchase system of MND and to suggest renewed roles of MND and the agro-food sector for better alliance. After evaluating the current food purchase system of MND, two main roles of MND were suggested: offering opportunities for Korean agro-food suppliers to sell their high-quality products and developing a purchase system to promote competition among suppliers. As the roles of the agro-food sector, stable supplying of cheap agro-food and...

The purpose of this paper is to contribute to the debate over agricultural trade and environment by asking: Does agricultural trade liberalization under free trade agreement (FTA) reduce pollution from agriculture?  In order to contribute to answering the above research question, we measure the potential impact of environmental pollution from agriculture caused by agricultural trade liberalization under the Japan-Korea FTA (JKFTA), using the Global Trade Analysis Project (GTAP) model and the OECD Nitrogen Balance Database.  The scenario we model assumes the complete removal of all import tariffs between Japan and Korea, not only in the agricultural sector but in non-agricultural sectors, as well.  The results show the JKFTA is likely to lead to an overall...

The Prospective Free Trade Agreement with Korea: Background, Analysis, and Perspectives for California Agriculture
Provedor de dados: 31
Autores: Lee,   Hyunok; Sumner,   Daniel A.
After several years of informal and formal negotiations, South Korea and the United States reached an agreement to move towards free trade in April 2007.  Currently, both countries await congressional approval before the agreement can be implemented. This study explains the substance of the agricultural parts of the agreement and considers its agricultural implications. The study finds that the Korea-United States Free Trade Agreement has the potential to be a significant demand driver for many sectors within California agriculture.   Despite its high import tariffs, tight import quota quantities and restrictive sanitary and phytosanitary regulations, South Korea has become a major agricultural importer from California. South Korea is an important export...

Market Concentration of the Processed Food in Korea
Provedor de dados: 31
Autores: Kim,   Sounghun.
In Korea, processed food markets have various shapes of structure: the markets of ice cream, special dietary food, noodles, sugar are highly concentrated, while the markets of gimchi, pickles, and ice are not very concentrated. The level of market concentration changes over time. These market structures and structural changes cause impacts on related industries as well as own industries. For the more successful policies, the paper suggests three ideas: to realize that each food processing industry has a different industry structure, to understand the relationship between the food processing industry and upstream and downstream industries and to take into account opinions  from various sources before adopting new policies.

In Korea, the portion of food industry has increased, while the portion of agriculture keeps decreasing. The alliance between agriculture and food industry results in the synergy between both industries as well as higher farmers' income. The goal of this study is to analyze the current status of the linkages between two food industries (fruit-juice industry and Korean-style meal franchise industry) and agriculture, and then to present the ways to strengthen the linkages. The discussion in this paper will be a policy baseline aiming for synergy between both industries, which is of a special concern to the next regime.

Estimation of Political Oligopoly Power of Domestic Producers in the Korean Raw-Milk Market
Provedor de dados: 31
Autores: Jeon,   Sang-Gon.
This paper estimates the political oligopoly power of domestic raw-milk producers in the Korean dairy market. Domestic raw-milk price for fluid use is decided exogenously by the government. The government announces the reference price of raw-milk price for fluid use to protect the domestic raw-milk producers from the potential market power of domestic dairy processors, because historically many small-sized domestic producers are a relatively weaker group than domestic processors. Here, this study has two questions: one is about how effectively the government protects the producers and the other is about how much the producers exert their political power against the government to raise the reference price in this process. Furthermore, this paper also tests...

The purpose of this study is to take a close look at Korea‘s biodiesel developing trends and assess economic feasibility based on benefit-cost analysis. This study finally presents directions to actively promote the biodiesel in Korea.  The role of bio-energy is significantly emphasized due to the continuous rise in oil price and environmental problems. According to some researches that have considered various factors such as breed, productivity, production costs and levels of technology, the most feasible bio-ingredients are rape and barley. By means of the benefit-cost analysis, rape has positive values in the net profits when considered with indirect benefits. Also, it is estimated that rape is feasible when produced in place of barley for...
