A Dynamic Optimal Crop Rotation Model in Acreage Response AgEcon
Cai, Ruohong; Bergstrom, John C.; Mullen, Jeffrey D.; Wetzstein, Michael E..
This paper presents a dynamic crop rotation model that shows how crop yield and price volatility could impact crop mix and acreage response under crop rotation considerations. Specifically, a discrete Markov decision model is utilized to optimize producers’ crop rotation decision within a finite horizon. By maximizing net present value of expected current and future profits, a modified Bellman equation helps develop optimum planting decisions. This model is capable of simulating crop rotations with different lengths and structures. Specifically, the corn-soybeans rotations were simulated using the crop rotation model.

A PROPOSED METHODOLOGY FOR ESTIMATING ECOREGIONAL VALUES FOR OUTDOOR RECREATION IN THE UNITED STATES AgEcon
Bhat, Gajanan; Bergstrom, John C.; Bowker, James Michael; Cordell, H. Ken.
This paper provides a methodology for the estimation of recreational demand functions and values using an ecoregional approach. Ten ecoregions in the continental US were defined based on similarly functioning ecosystem characters. The individual travel cost method was employed to estimate the recreational demand functions for activities such as motorboating and waterskiing, developed and primative camping, coldwater fishing, sightseeing and pleasure driving, and big game hunting for each ecoregions. Estimates of per trip net income value range from $12.93 to $218.38 while per day estimates range from $4.31 to $109.19. While our ecoregional approach differs conceptually from previous work, our results appear consistent with the previous travel cost...

A Pseudo-Sequential Choice Model for Valuing Multi-Attribute Environmental Policies or Programs in Contingent Valuation Applications AgEcon
Volinskiy, Dmitriy; Bergstrom, John C.; Cornwell, Christopher M.; Holmes, Thomas P..
The assumption of independence of irrelevant alternatives in a sequential contingent valuation format should be questioned. Statistically, most valuation studies treat nonindependence as a consequence of unobserved individual effects. Another approach is to consider an inferential process in which any particular choice is part of a general choosing strategy of a survey respondent. A stochastic model is suggested, consistent with the reflexivity, transitivity, and continuity axioms of utility analysis. An application of this theoretical model to the valuation of watershed ecosystem restoration demonstrates that an empirical model recognizing reflexivity and transitivity, and also allowing for continuity, shows the highest in-sample predictive ability.

A Pseudo-Sequential Choice Model for Valuing Multiple Environmental Policy or Program Components in Contingent Valuation Applications AgEcon
Volinskiy, Dmitriy; Bergstrom, John C.; Cornwell, Christopher M..
The study proposes a discrete-choice model for environmental policy/program valuation, to be used in cases when several policies are valued sequentially. The stochastic specification of the model is consistent with the transitivity and continuity axioms of utility analysis. An empirical methodology for the model is suggested. An application of this model to WTP estimation for Little Tennessee River watershed ecosystem restoration is provided. Findings from the application agree with the hypothesized agent's behavior.

A Spatiotemporal Fixed Effects Estimation of U.S. State-Level Carbon Dioxide Emissions AgEcon
Burnett, J. Wesley; Bergstrom, John C..
One of the major shortcommings of past environmental Kuznets curve (EKC) studies is that the spatiotemporal aspects within the data have largely been ignored. By ignoring the spatial aspect of pollution emissions past estimates of the EKC implicitly assume that a region’s emissions are unaffected by events in neighboring regions (i.e., assume there are no transboundary pollution emissions between neighbors). By ignoring the spatial aspects within the data several past estimates of the EKC could have generated biased or inconsistent regression results. By ignoring the temporal aspect within the data several past estimates of the EKC could have generated spurious regression results or misspecified t and F statistics. To address this potential...

A TEST OF CONTINGENT MARKET BID ELICITATION PROCEDURES FOR PIECEWISE VALUATION AgEcon
Bergstrom, John C.; Stoll, John R..
Economists are frequently faced with the task of valuing commodity package components. The valuation of specific impacts of public policies is a case in point. Two contingent market bid elicitation procedures were tested for valuing changes in single components of multicomponent government program. Results of the test suggested that respondents provided more accurate component to piecewise valuation when a two-step bidding approach, rather than a one-step approach was used. Thus, there is evidence that a two-step approach which helps respondents to isolate valuations for package components is perhaps a preferable bid elicitation procedure for piecewise valuation.

Accounting for Geographic Heterogeneity in Recreation Demand Models AgEcon
Sardana, Kavita; Bowker, James Michael; Bergstrom, John C.; Starbuck, C. Meghan; English, Donald B.K..
Spatial differences in site characteristics and user populations may result in heterogeneity of recreation preferences and values across geographic regions. Non-linear mixed effects models provide a potential means of accounting for this heterogeneity. This approach was tested by estimating a national-level recreation demand model with encouraging results.

AN ANALYSIS OF WILLINGNESS TO PARTICIPATE IN WILDERNESS OR OTHER PRIMITIVE AREAS AgEcon
Adhikari, Murali; Bergstrom, John C.; Houston, Jack E.; Bowker, James Michael; Paudel, Laxmi; Cordell, H. Ken.
A logit model was used to determine the major factors explaining willingness to participate of an individual in the wilderness or other primitive area visits. The results of the study showed that education and environmental awareness were in wilderness participation decision. Demographic variables like age, race, and sex also were statistically significant and emerged as important policy variables in defining wilderness participation behavior. Characteristics of wilderness areas like crowdness, pollution, and poor management failed to produce any significant impacts in the decision making process of wilderness area visit.

An Economic Valuation of Pollination Services in Georgia AgEcon
Barfield, Ashley; Bergstrom, John C.; Ferreira, Susana.
The production of many crops depends on biotic pollination. As pollinator populations decline, assessments of the potential consequential loss of economic value are critical. We estimate the economic value of pollination services ($608 million), crop vulnerability ratio (21 percent), and pollination’s contribution to agricultural production value (5 percent) for Georgia.

AN ECOREGIONAL APPROACH TO BENEFIT TRANSFER AgEcon
Bhat, Gajanan; Bergstrom, John C.; Bowker, James Michael.
This study has examined the transferability of consumer's surplus estimates (fixed value transfer) and transferability of benefit functions from the Southern Appalachian Mountain ecoregion to a local site within the ecoregional level. Given data used in this study, it is found that transferability of benefit estimated are possible in 50% of the activities, whereas benefit functions can be transferred in all of the activities considered in this study. The results are compared to previous studies. Different problems in testing benefit estimates transfer are discussed.

APPLICATION OF EXPERIMENTATAL ECONOMICS CONCEPTS AND PRECEPTS TO CVM FIELD SURVEY PROCEDURES AgEcon
Bergstrom, John C.; Stoll, John R..
Experimental economics (EE) axioms are directly applied in this paper to contingent valuation method (CVM) field survey procedures. The implications of EE concepts and precepts for conceptualizing and handling potential CVM biases and framing effects also are discussed. It is concluded that EE concepts and precepts provide useful principles and guidelines for CVM field survey procedures.

Assessing the Effects of Climate Change on Farm Production and Profitability: Dynamic Simulation Approach AgEcon
Cai, Ruohong; Bergstrom, John C.; Mullen, Jeffrey D.; Wetzstein, Michael E..
In this paper, a dynamic optimization model was developed to simulate how farm-level realized price and profitability respond to yield change which was induced by climate change. Producers' acreage response was included in the dynamic model considering crop rotation effect. In the crop rotation model, a modified Bellman equation was used to dynamically optimize the net present value of farm profit for a five-year interval. This simulation process was repeated through the year 2050. Then yield, price, and acreage response were compiled to generate realized profit. Results generally indicated that reduction in crop yields due to climate change results in reduced farm profitability for most of the states studied. Predicted climate change is more likely to...

BENEFITS TRANSFER AND COUNT DATA TRAVEL COST MODELS: AN APPLICATION AND TEST OF A VARYING PARAMETER APPROACH WITH GUIDED WHITEWATER RAFTING AgEcon
Bowker, James Michael; English, Donald B.K.; Bergstrom, John C..
We combine currently popular count data methods with earlier work by Vaughan and Russell on varying parameter travel cost models to model trip demand and calculate consumer surplus. We test and reject the hypothesis that per trip consumer surplus from guided rafting is invariant to river characteristics. We then develop and test a series of benefit transfer functions against benefits derived from individual river models. Our findings suggest that this flexible form of count data model offers considerable promise as a benefit transfer function.

CURRENT STATUS OF BENEFITS TRANSFER IN THE U.S.: A REVIEW AgEcon
Bergstrom, John C..
Benefits transfer refers to the use of existing benefit estimates in a different, but similar context as compared to the original study which generated the benefit estimates. Benefits transfer techniques include fixed value transfer, expert opinion, and value estimator models. Although benefits transfer techniques are subject to a number of conceptual and empirical limitations, these techniques are widely applied in the United States in economic assessments of public policies and projects. The application of benefits transfer in natural resource damage assessment cases is relatively untested in the United States court system.

ECONOMIC IMPACTS OF STATE PARKS ON STATE ECONOMIES IN THE SOUTH AgEcon
Bergstrom, John C.; Cordell, H. Ken; Watson, Alan E.; Ashley, Gregory A..
The economic impacts of recreational visits to state parks on the economies of North Carolina, South Carolina, Georgia, and Tennessee were estimated using the U.S. Forest Service IMPLAN input-output modeling system. Recreational expenditure data associated with state parks were obtained from the Public Area Recreation Visitors Study (PARVS). Results suggest that recreational spending may stimulate a considerable amount of economic activity in the state economies studied. Hence, future research into the economic development potential of outdoor recreation seems warranted.

EFFECTS OF RESERVOIR AQUATIC PLANT MANAGEMENT ON RECREATIONAL EXPENDITURES AND REGIONAL ECONOMIC ACTIVITY AgEcon
Bergstrom, John C.; Teasley, R. Jeff; Cordell, H. Ken; Souter, Ray A.; English, Donald B.K..
Exotic aquatic plant management is a major concern for public reservoir management in many regions of the United States. A study was conducted to measure the effects of alternative aquatic plant management strategies on recreational expenditures and regional economic activity. The study areas was Lake Guntersville, Alabama, and the local economy surrounding the lake. Lake Guntersville is one of the largest reservoirs in the Tennessee Valley Authority system. Results suggested the relatively moderate levels of aquatic plant control are associated with the highest levels of recreation-related economic effects on the economy surrounding Lake Guntersville.
