Eficiencia tecnica en pesquerias multiespecie: una aproximacion primal AgEcon
Orea, Luis; Pinilla, Antonio Alvarez.
RESUMEN: El objetivo de este trabajo es estudiar, desde el punto de vista primal, la eficiencia técnica de una muestra de barcos dedicados a la pesca de merluza en Asturias. Un rasgo característico de esta actividad es la importancia que tienen las capturas de otras especies distintas de la merluza. La naturaleza multiproducto de esta actividad plantea distintas alternativas de modelización. En este trabajo se comparan los resultados obtenidos a partir de la estimación de una función de producción agregada, una función de producción multiproducto y una función de distancia. Los tres modelos se estiman utilizando el estimador intragrupos. En una segunda etapa, los índices de eficiencia se calculan a partir de los efectos individuales una vez eliminada la...

India's Reform of External Sector Policies and Future Multilateral Trade Negotiations AgEcon
Srinivasan, T.N..
I evaluate India's transition from an inward-oriented development strategy to greater participation in the world economy. While tariff rates have decreased significantly over the past decade, India is still one of the more autarkic countries. Despite improvement over the past in export performance, India continues to lag behind its South- and East Asian neighbors. Second, official debt flows have been largely replaced by foreign direct investment (FDI) and portfolio investment in the 1990s. India's ability to attract FDI would be greatly enhanced by further reforms. I argue that India's participation in a future round of multilateral trade negotiations would benefit India. I outline the further reforms most needed: reform of labour and bankruptcy laws,...

SPATIAL INTEGRATION OF MAIZE MARKETS IN POST-LIBERALIZED UGANDA AgEcon
Rashid, Shahidur.
Using weekly price data for two sub-periods, this paper analyzes how Ugandan maize market performed in the years following agricultural market liberalization in the early 1990’s. For each time period, the extent of integration, causality among spatial locations, and relative importance of spatial locations in price formation are examined. The extent of integration, defined as a set of markets that shares common long-run price information, and the causal relationships among markets have been tested within Johansen’s cointegration framework. The relative importance of each market locations is examined by estimating the common trend coefficients with a dynamic vector moving average model. Results indicate that, while there has been an overall improvement in...
