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...

Dynamics of Heterogeneous Congestion Tolerance in the Location Choices of U.S. Gulf of Mexico Shrimp Fishermen AgEcon
Ran, Tao; Keithly, Walter R., Jr.; Kazmierczak, Richard F., Jr..
Location choice is one of the most important short-run decisions made by commercial fishermen. Previous studies of location choice by commercial fishermen have focused primarily on site fidelity, profit-maximization behavior, and risk attitudes as factors influencing their location choice behavior. Although the recreational literature gives extensive consideration to the influence of congestion on site selection, few studies have considered the influence of congestion tolerance on site selection in the commercial fishing sector. This study uses a mixed logit model to analyze the heterogeneous congestion tolerance in location choice among U.S. Gulf of Mexico shrimp fishermen. The dynamics of fishermen responses to economic conditions are compared and...

Estimating Equilibrium Models of Sorting Across Locations AgEcon
Bayer, Patrick; Timmins, Christopher.
With the growing recognition of the role played by geography in all sorts of economic problems, there is strong interest in measuring the size and scope of local spillovers (i.e., simple anonymous agglomeration or congestion effects, or more complicated interactions between individuals or firms of specific types). It is well-understood, however, that such spillovers cannot be distinguished from unobservable local attributes using just the observed location decisions of individuals or firms. We propose an empirical strategy for recovering estimates of spillovers in the presence of unobserved local attributes for a broadly applicable class of equilibrium sorting models. This approach relies on an instrumental variables strategy derived from the internal...

Forest Amenities and Location Choice in the Southwest AgEcon
Hand, Michael S.; Thacher, Jennifer A.; McCollum, Daniel W.; Berrens, Robert P..
Locations with natural characteristics, such as forest, are thought to be attractive residential locations. This proposition is tested in the Southwest United States, composed of Arizona and New Mexico. This paper presents a conditional logit model of location choice estimated with household observations from the U.S census, geographic information system (GIS) data, and county-level data. Results suggest that forest area, both in one's own location and nearby, increases the probability of choosing a location. But significant heterogeneity in location choices exists; an income effect and life-cycle effects on the demand for forest amenities appear to determine location choices.

Location Choice Behavior of Gulf of Mexico Shrimpers under Dynamic Economic Conditions AgEcon
Ran, Tao; Keithly, Walter R., Jr.; Kazmierczak, Richard F., Jr..
This study uses a mixed logit model to analyze monetary and nonmonetary factors that influence location choice behavior of the U.S. Gulf of Mexico shrimpers. Shrimpers’ responses to economic conditions are compared and contrasted for two periods related to changing economic conditions in the industry. Results show that even though shrimpers are generally revenue driven in choosing a fishing site, their past experience also plays an important role. Further, changes in economic conditions appear to exhibit an influence on the risk attitudes of some shrimpers.

Spatial Dynamics of the Livestock Sector in the United States: Do Environmental Regulations Matter? AgEcon
Herath, Deepananda P.B.; Weersink, Alfons; Carpentier, Chantal Line.
This study examines the factors affecting state annual share of national inventory for each of the hog, dairy, and fed-cattle sectors using data from the 48 contiguous states for 1976 to 2000. The paper develops a state specific, time-series environmental stringency measure and introduces instrumental variables to control for the possible endogeneity bias between livestock production decisions and regulatory stringency. The results indicate that differences in the severity of environmental regulations facing livestock producers have had a significant influence on production decisions in the dairy, and particularly the hog sector.
Tipo: Journal Article Palavras-chave: Environmental regulation stringency; Fixed-effects model; Instrumental variable; Livestock production; Location choice; Panel data analysis; Pollution havens; Environmental Economics and Policy.
