We divide countries into two technology categories: developed and developing. Agricultural efficiency within each technology category was calculated. Cross-category efficiency measures were developed and combined with own-category measures to develop a technical difference index. Results...

Numerous methods for measuring multifactor productivity have been used by economists. This report uses a recently developed approach, data envlopment analysis, to measure productivity. This method can be used not only to calculate productivity but also to divide productivity measures into...

Brazil's agricultural sector underwent major changes in the past two decades. Though Brazil is abundant in labor, land, and animal power, government subsidies encouraged the use of fertilizer and machines. Since productivity growth arises from technical change, Brazil's drive to modernize its...

A central theme of international trade research has been the impact of trade liberalization on productivity. Early literature on this theme points out that trade liberalization brings resource/organizational adjustment across industries and this adjustment enhances productivity. A traditional...

Pro-poor growth has been identified as one of the most promising pathways to achieve the Millennium Development Goals (MDGs) or any subsequent set of goals aiming to reduce poverty worldwide. Related research has developed a multitude of instruments to measure pro-poor growth using absolute and...

This paper investigates the nonparametric analysis of technology under non-convexity. The analysis extends two approaches now commonly used in efficiency and productivity analysis: Data Envelopment Analysis (DEA) where convexity is imposed; and Free Disposal Hull (FDH) models. We argue that, while...

The Gulf of Mexico (GOM) is the primary producer of shrimp in the United States and annual production from this region has remained relatively constant over the past several decades. By comparison, U.S. shrimp imports have increased from about 400 million pounds annually during the early 1990s...

The organic milk pay price is more stable year round and increases every year. However, the conventional milk price varies within the year and from year to year. As an emerging segment of the milk industry, consumer demand for organic milk is increasing rapidly. The growth in demand relative to...

We present a dynamic intraseasonal model of optimal investment in irrigation precision that takes into reductions in disease losses and acceleration of crop growth as well as water savngs. We derive the optimal levels of water use, investment in precision equipment and timing of harvest under...

India has enjoyed rapid economic growth over the past forty years, GDP per capita (PPP$) accelerating from less than 1% in the 1970s to over 5.8% in the 2000s. As incomes have risen, consumer demand has shifted from staple grains toward higher valued foods, such as horticultural and livestock...
