We estimate both averting behavior and stated preferences about water quality improvements in the southeastern Anatolian region using reduced form equations. The model reveals that income, education, perception about water features, household living conditions, regional variables are only statistically significant in both the RP and SP data models. The WTP estimate was around 6.43 New Turkish Liras. And also simulation analysis show that increasing income and education foster the willingness-to-pay for treating water, while an increase in bid prices and perception reduce the WTP.

We applied a multinomial logit model to determine consumer characteristics affecting three possible policy regulations that wanted to be implemented for genetically modified foods in Turkey. The study reveals that many household characteristics including food spending amount, education, gender, marital status, knowledge about food related policies and regional variables are key policy factors to choose regulation programs on GMO foods. People are more prone to implement compulsory policy on GMO foods than that of voluntary policy.

In selecting a marketing channel for fresh peach sales, Georgia commercial peach growers choose the channel after accounting for buyers' preferences for quality attributes. Using the polychotomous selection model and survey data we identified external and internal quality attributes as essential factors influencing the choice of a marketing channel and the share of the crop marketed. Other factors influencing the choice and the volume sold through each marketing channel included orchard characteristics and the variety-determined fruit maturity.

This paper identifies factors that influence the demand for a black bass fishing trip taken in the Southeastern U.S. using a double hurdle negative binomial count data model. The probability of fishing for a black bass is estimated in the first stage and the trip frequency for fishing a black bass is estimated in the second stage given that the individual has a positive probability towards undertaking a black bass fishing trip in the Southeast. The applied approach allows the decomposition of the effects of factors responsible for the decision of taking a fishing trip and the number of trips.

EXPLANING ANGLERS BEHAVIOR USING COUNT DATA MODELS WITH ENDOGENOUS SWITCHING REGIME

A two stage model describes the behavior of anglers who fish with or without a license. The proposed multinomial logit-count data model examines characteristics influencing those who fish for recreation and those who may choose to fish to supplement their food budgets. The model is estimated using data from the national survey. Results show, among others, that anglers who fish to supplement their diet are more likely to come from households run by women, with less income and were less educated than those who fished for recreational purposes.

We extend the double-hurdle count data model to account for a joint decision in the first stage in which the individual jointly makes a decision about a participation in fishing and a site (region) selection decision. Contrary to the conventional the double-hurdle count data model, our model discriminates between the effects of non-participant and potential participants (e.g., potential participants are those who participated in fishing but may or may not take a trip to a specific site, the Southeastern U.S.) on the probability of taking a fishing trip.

Growth Expectations and Decision to Renovate a Golf Course: An Application of a Censored Model with the Simultaneity Test

Golf course renovation and expected business growth were examined. Endogeneity test on the renovation decision and a censored expected growth model rejected the hypothesis of simultaneity and decisions were modeled separately. Key determinants for both decisions were golf facility features, but not respondents' characteristics.
