A TWO-STEP ESTIMATOR FOR A SPATIAL LAG MODEL OF COUNTS: THEORY, SMALL SAMPLE PERFORMANCE AND AN APPLICATION AgEcon
Lambert, Dayton M.; Brown, Jason P.; Florax, Raymond J.G.M..
Several spatial econometric approaches are available to model spatially correlated disturbances in count models, but there are at present no structurally consistent count models incorporating spatial lag autocorrelation. A two-step, limited information maximum likelihood estimator is proposed to fill this gap. The estimator is developed assuming a Poisson distribution, but can be extended to other count distributions. The small sample properties of the estimator are evaluated with Monte Carlo experiments. Simulation results suggest that the spatial lag count estimator achieves gains in terms of bias over the aspatial version as spatial lag autocorrelation and sample size increase. An empirical example deals with the location choice of single-unit start-up...

Análisis del impacto medioambiental derivado de las actividades económicas. Aplicación a una economía regional AgEcon
Flores, Monica; Mainar, Alfredo J..
The goal of this paper is to analyse the households’ environmental impact in a regional economy, including the household direct impact as well as the impact associated with the production of goods and services of the household demand. Moreover, per capita ecological impacts for each household category according to income level are obtained. We focus on water consumption, and water and atmospheric pollution. The framework is based on a regional SAMEA (Social Accounting Matrix and Environmental Accounts), and vertically integrated environmental indicators using the Leontief model. An application is carried out for the Aragon case.

Carbon Credit Payment Options for Agroforestry Projects in Africa AgEcon
Allwardt, Jennifer.
The potential of using carbon offset credits from agroforestry projects for farmers in developing areas has become more prevalent in both Clean Development Mechanism and voluntary carbon markets. Since the implementation of the Kyoto Protocol, many international development organizations have been interested in using the Clean Development Mechanism (CDM) to help both mitigate CO2 emissions through agroforestry projects offsets and as a poverty reduction tool. Few organizations that have begun talking with farmers about planting trees for carbon offset credits have been able to tell the farmers how much money they would receive from their new tree growth or the costs they will incur in doing so. For this study, a whole farm budget toolkit was designed to...

DER OSTDEUTSCHE AGRARSEKTOR IM TRANSFORMATIONSPROZESS - AUSGANGSSITUATION, ENTWICKLUNG UND PROBLEMBEREICHE AgEcon
Rothe, Andrea; Lissitsa, Alexej.
This Discussion Paper focuses on developments of the agricultural sector in the federal states of the former Eastern Germany after German reunification. Descriptive analysis is involved to display problems of transition process and changes in agricultural production and structures. The results of the analysis report considerable differences in the agricultural sector between New and Old Federal States after 15 years after the reunification. These differences are especially to find in a variety of existing legal forms, considerably higher share of rented land, lower cattle stock as well as larger farm size of the farms in the New Federal States. Observed structural changes of the German agricultural sector display that due to European Union measures the...

DETERMINANTS OF INVESTMENT FLOWS IN U.S. MANUFACTURING AgEcon
Brown, Jason P.; Florax, Raymond J.G.M.; McNamara, Kevin T..
The purpose of the paper is to test the long-run steady state of growth factors hypothesized to influence U.S. manufacturing investment flows. These factors include agglomeration, market structure, labor, infrastructure, and fiscal policy. Spatial cross-regressive and spatial Durbin models are used to measure the spatial interaction of investment flows. Spatial spillovers are found to be of a competitive nature at the state level, implying that a factor which attracts more investment to a particular state is associated with lower investments in neighboring states. Investment flows to states with higher market demand, more productive labor, and more localized agglomeration of manufacturing activity.

Food Markets, Policy, and Technology: The Case of Honduran Dry Beans AgEcon
Martel, Pedro V.; Bernsten, Richard H.; Weber, Michael T..
To identify constraints and options to increase bean subsector’s productivity, 239 farmers and 57 city traders were surveyed, and a rapid appraisal of the El Salvadorian market was conducted. Data were analyzed with descriptive statistics, logistic analysis, and linear regression analysis. This research shows that farmers' socioeconomic characteristics, production environments, and institutional factors all affect the varietal adoption process.

Location of Production and Consolidation in the Processing Industry: The Case of Poultry AgEcon
Goodwin, Harold L., Jr..
The poultry industry is the most vertically integrated of U.S. agriculture and food production and is rapidly progressing toward being one of the most concentrated. In 2002, the top 15 broiler states accounted for 94.4% of U.S. production. From 1982-2002, the top four broiler firms had a fivefold increase in Ready-to-Cook (R-T-C) pounds, a tripling of plants and four-and eight-firm concentration ratio increases of 27.9% to 48.2% and 44.1% to 66.6%. In a broad sense, chicken became more affordable, appealing, and available; total R-T-C pounds increased from 234 to 663 million pounds between 1982 and 2002.

Productivity Spillovers from Foreign MNEs on Domestic Manufacturing Firms: Is Co-location Always a Plus? AgEcon
Mariotti, Sergio; Mutinelli, Marco; Nicolini, Marcella; Piscitello, Lucia.
The paper analyses productivity spillovers from foreign MNEs on domestic manufacturing firms. Using a database on foreign MNEs in Italy, our results reveal that local firms do benefit from the presence of foreign MNEs, and the effect is higher when local and foreign firms in manufacturing sectors are co-located. However, spillovers benefiting domestic firms are likely to be less influenced by co-location when foreign MNEs are in services sectors as the latter are different from manufacturing industries under a number of aspects that overcome the effect of distance. Indeed, in these sectors, proximity and interaction are often obtained through professional mobility and temporary inter-organizational routines.
