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...

In this paper we assess the performance of farmers adopting an improved sorghum technology package in the Maradi region of Niger. A propensity score matching method is used to address self-selection bias into the program. First, we estimate a propensity model to participate in the extension...

Labor productivity is measured for each of 4 selected years for each of four components of personal consumption expenditures for food: food purchased for off-premises consumption, purchased meals and beverages, food furnished Government and commercial employees, and food produced and consumed on...

Minnesota's Economy Compares Favorably To That Of Neighboring States And The U.S.

Poverty is not evenly distributed across the American landscape. At the county level of aggregation, poverty is overwhelmingly a rural problem, with the most remote rural places at the greatest disadvantage. 1 Although research has shown that “place matters†in poverty outcomes and...

This paper investigates the impact of an expansion in agricultural processing on the Western Australian economy by modifying and applying a Computable General Equilibrium (CGE) economic model of Western Australia (called WAM). WAM was used to simulate the effects of a $1 million expansion in...

The performance of pulp and paper industries in four Canadian regions is compared based on the estimation of an input distance function both with and without pollutant outputs. The environmentally sensitive approach provides higher productivity growth estimates for all regions, indicating the...

This paper considers the stochastic production frontier approach to analyse the technical efficiency and its determinants of fish farms in Ghana using a cross-section data of 150 farms. It considers the explicit effects of family and hired labour on production by setting the log-value of the...

We investigate the existence of an inverse relationship (IR) between farm size and technical efficiency in Philippine brackishwater pond aquaculture. The study is motivated by the exemption of fish ponds from the Comprehensive Agrarian Reform Laws and suggestions in the literature of inefficient...
