We estimate a random effects stochastic frontier production function to study the impacts of irrigation on factor use on low-income rice farms in the Philippines. Irrigation precipitates a release of labor and an increase in use of fertilizer and pesticides. We find only weak statistical support...

Do the most promising policies to promote sustainable upland farming originate at the local or national level? Will coordination of local and national efforts produce better outcomes? This paper uses an optimization-simulation model of the Manupali watershed in the Philippines to investigate...

Approximately 90 percent of the world's production and consumption of rice occurs in Asia, and regional demand is projected to increase by 70 percent over the next 30 years. Meeting this demand requires an expansion of the total area under irrigation in the coming decades. In this article, the...

A térbeli számszerűsített általános egyensúlyi modellek az új gazdaságföldrajz empirikus alkalmazásainak eszközei. Szemléleti-módszertani gyökereiket tehát az új gazdaságföldrajzi és a számszerűsített általános egyensúlyi modellekben találjuk meg. Tanulmányunkban a...

fejlesztése a Pécsi Tudományegyetem Közgazdaságtudományi Karán folyó kutatások eredménye. A modellezési irányzat elsõ megvalósulása a Nemzeti Fejlesztési Hivatal számára kidolgozott és az 1. Nemzeti Fejlesztési Terv (2004-2006) hatáselemzésére alkalmazott EcoRET modell. Az...

The paper examines a method to attribute hazardous waste streams to regional production and consumption activity, and to connect these same waste streams through to different management options. We argue that a method using an input–output framework provides useful intelligence for decision...

Amid changing attitudes about the environment and emerging sustainability concerns in the late 1960s and 1970s, countries around the world began regulating multiple aspects of solid and hazardous wastes. Initial regulations and those occurring since all share the broader goal of curbing waste...

This paper presents theory and methods used to construct an interregional commodity by industry flow matrix for the United States. The interregional flow matrix method involves the construction of single-state (and DC) social accounting matrices (SAMs) using data derived from IMPLAN. Once...

The lack of consistent, reliable data on interregional trade and interindustry transactions hampers complete analysis of regional models. This study implements and tests interindustry transaction flows in a national system of economic regions derived from an interregional accounting framework...
