Site-specific application of manure has the potential to improve crop production and environmental quality. If manure is applied where it is needed, in the quantity required by the crop, over application, with attendant runoff and leaching problems can be reduced. To implement this approach...

Spatial accessibility is concerned with the opportunity that an individual at a given location possesses to participate in a particular activity or set of activities. The main objective of this paper is to highlight the shortcomings of traditional accessibility measures and provide some...

This research explores how recreational values change over time. Hedonic functions linking travel costs to site amenities are estimated using data on nearly 70,000 visitors to Ohio State Parks from 1997 to 2002. The results suggest substantial changes in recreational values over time. Effects...

Deterministic rules for generating choice sets are often employed by analysts confronting universal sets with large numbers of alternatives. For destination choice analysis, site exclusion rules defined by travel time, distance, or quality have a behavioral appeal, yet are fundamentally limited...

This study examines the factors the influence the values and importance that landowners place on the attributes of voluntary wetland restoration programs. Choice-based conjoint analysis, a stated preference method, was used to estimate the marginal utilities and values for restoration program...

Endogenous variables in structural models of agricultural commodity markets are typically treated as stationary. Yet, tests for unit roots have rather frequently implied that commodity prices are not stationary. This seeming inconsistency is investigated by focusing on alternative specifications...

This paper addresses conceptually and empirically some of the biases commonly associated with contingent valuation (CV) elicitation of willingness to pay (WTP) values for non-market goods and services. More specifically, the study focuses on testing for scope, context, and sequence effects in CV...

This paper proposes a nonparametric bias-reduction regression estimator which can accommodate two empirically relevant data environments. The first data environment assumes that at least one of the predictor variables is discrete. In such an empirical framework, a "cell" approach, which consists...

This study estimates a cross-sectional model through a theoretically consistent Almost Ideal Demand System (AIDS) to examine the economic and demographic determinants of food consumption patterns in Japan over life-cycle periods. Results show key factors that explain such behavior, including...

In this paper we derive a joint continuous/censored demand system suitable for the analysis of commodity demand relationships using panel data. Unobserved heterogeneity is controlled for using a correlated random effects specification and a Generalized Method of Moments framework used to...
