Species Diversity in the Parasitoid Genus Asobara (Hymenoptera: Braconidae) from the Native Area of the Fruit Fly Pest Drosophila suzukii (Diptera: Drosophilidae) Naturalis
Guerrieri, E.; Giorgini, M.; Cascone, P.; Carpenito, S.; Achterberg, C. van.
Drosophila suzukii (Matsumura), commonly known as Spotted Wing Drosophila (SWD), is a worldwide serious economic threat to the production of berries and stone fruits. The chemical control widely used against this pest is often not able to preventing yield losses because wild flora offers an abundance of fruits to D. suzukii where the pest is able to reproduce and from where it recolonizes neighbouring cultivated fields. Alternatively, within Integrated Pest Management protocols for D. suzukii, biological control could play a key role by reducing its populations particularly in non-cultivated habitats, thus increasing the effectiveness and reducing the side negative effects of other management strategies. Because of the scarcity and of the low efficiency of...

Bilateral Trade and Economic Growth: The Empirical Evidence Between U.S. and South Korea AgEcon
Kang, Hyunsoo; Kennedy, P. Lynn.
This paper analyzes the relationships between bilateral trade and economic growth in the U.S. and Korean economies. Using quarterly data from 1990 to 2008, the theoretical procedures utilize Ordinary Least Square (OLS) and Seemingly Unrelated Regression (SUR) models under the static model assumption, an Impulse Response Function (IRF) and Forecast Error Variation Decomposition (FEVD) under the Vector Autoregressive (VAR) model, and Granger causality tests. Empirical results indicate a causal relationship between bilateral export growth and economic growth for the U.S. and Korean economies. The export-led growth (ELG) hypothesis is strongly supported by the results of Granger causality tests on Korean exports.
Tipo: Journal Article Palavras-chave: Export-led growth; Bilateral trade; Granger causality; South Korea; United States; International Relations/Trade; Political Economy; Production Economics.

VERTICAL COORDINATION OF MARKETING SYSTEMS: LESSONS FROM THE POULTRY, EGG, AND PORK INDUSTRIES AgEcon
Martinez, Stephen W..
The economic development of South Korea is often considered a model for developing countries. We use 1975 and 1990 data in a general equilibrium framework with a highly disaggregated sector specification to evaluate the opportunity cost of its agricultural protection. We show that although agriculture's share of the gross domestic product (GDP) declined between 1975 and 1990, the cost of agricultural protection, as measured by the loss in GDP, did not fall. The larger gap between domestic and world prices for the protected sectors exacerbated the distortions in resource allocation. Simulated removal of 1990 agricultural border protection reduced the share of agricultural GDP to the level actually observed in 1996, demonstrating how protection can impede...

South Korea Agriculture Policy Review AgEcon
Gurung, Rajendra Kumar; Pa, Chung; Deng, Hugh.
South Korea is a highly urbanized and industrialized country. Increased urbanization and greater specialization have led to rising incomes, and changes in food production and consumption patterns. Changes in consumption and increased production specialization have also resulted in changes in trading patterns, with South Korea emerging as a leading importer of agri-food products. South Korea places great importance on self-sufficiency in food staples, and achieving income parity between rural and urban households. To attain these goals, considerable support has been provided to its agriculture sector. South Korea's policy support to the agriculture sector ranks among the worlds' highest. Small holdings still persist, entry into the sector is difficult, and...

The Impact of Foot and Mouth Disease Outbreaks in Taiwan and South Korea on the Red Meat Industries in Canada and the United States AgEcon
Charlebois, Pierre; Gagne, Stephan.
In addition to trade liberalization, other factors have contributed to the strong growth of red meat production in Canada since the end of the 1980s. In particular, the outbreaks of foot and mouth disease (FMD) in Taiwan and in South Korea eliminated two competitors in the Japanese market. This reduction in supply caused an increase in the price of hogs in the United States and Canada of 2.5% and 3% respectively during the 1997 to 2007 period. The higher price stimulated Canadian production by an average of 5%, and by 2% in the United States. Annual agricultural farm receipts from the hog market were greater by an average of $CD 276 million (9%) for a grand total of $CD 3 billion over the 11 years. Moreover, the value added in the red meat processing...
