`Been there done that': Disentangling option value effects from user heterogeneity when valuing natural resources with a use component.

Endogeneity bias arises in contingent valuation studies when the error term in the willingness to pay (WTP) equation is correlated with explanatory variables because observable and unobservable characteristics of the respondents affect both their WTP and the value of those variables. We correct for the endogeneity of variables that capture previous experience with the resource valued, humpback whales, and with the area of study. We consider several endogenous behavioral variables, so we apply a multivariate probit approach to jointly model them with WTP. In this case, correcting for endogeneity increases econometric efficiency and substantially corrects the bias affecting the estimated coefficients of the experience variables, by isolating the decreasing effect on option value caused by having experienced the resource. Stark differences are unveiled between the marginal effects on willingness to pay of experience of the resources in an alternative location versus experience in the location studied

Estimating the willingness to pay for community healthcare insurance in rural Nigeria

Health care financing in Nigeria is dominated by private out-of-pocket payment that is not affordable to the poor. This has greatly reduced access to quality health care for the predominantly rural poor. Insurance schemes as options for increasing access to health care services have not received considerable attention in Nigeria. In this regard, a community health prepayment scheme is proposed, and the Contingent Valuation Method is used to investigate the willingness of rural households to pay for this scheme. Contributing through agricultural commodities produced statistically higher estimates than through direct cash. Also, by incorporating uncertainty in responses using the Random Valuation Model, higher contribution amounts were obtained. This provides an option for its use in healthcare contingent valuation studies where respondents are uncertain about their true responses. The groups that are willing to pay lesser amounts into the scheme as compared with their counterparts are women, the less educated, and the less wealthy households.Health care financing, Prepayment scheme, contingent valuation, willingness to pay, dichotomous choice, uncertainy, random valuation, stochastic payment card

Knowledge Management What Can Organizational Economics Contribute?

Knowledge management has emerged as a very successful organization practice and has been extensively treated in a large body of academic work. Surprisingly, however, organizational economics (i.e., transaction cost economics, agency theory, team theory and property rights theory) has played no role in the development of knowledge management. We argue that organizational economics insights can further the theory and practice of knowledge management in several ways. Specifically, we apply notions of contracting, team production, complementaries, hold-up, etc. to knowledge management issues (i.e., creating and integration knowledge, rewarding knowledge workers, etc.) , and derive refutable implications that are novel to the knowledge management field from our discussion.Transaction costs, organizational economics

Respondent uncertainty in contingent valuation: the case of whale conservation in Newfoundland and Labrador

In this paper we investigate the issue of respondent uncertainty in contingent valuation studies while estimating the willingness to pay for a whale conservation program o¤ the coasts of Newfoundland and Labrador. We use data from a phone survey administered to a sample (N=614) of adult Canadians, proposing a policy consisting of subsidizing and enforcing the use of acoustic devices that would reduce the likelihood that whales become entangled in �shing nets. A follow-up question asked respondents how certain they were about their answer to the main dichotomous-choice question, which allows us to investigate how the treatment of uncertainty a¤ects value measures. A mean willingness to pay of about $81/year per respondent is estimated when accounting for the degree of certainty with which respondents expressed their willingness to pay. We also analyze payment vehicle e¤ects using a split-sample approach whereby some respondents were asked a dichotomous-choice question about a tax contribution while others were asked about a voluntary donation instead.contingent valuation; whales; preference uncertainty; dichotomous choice; payment vehicle; willingness to pay

N.C. Medicaid Reform: A Bipartisan Path Forward

The North Carolina Medicaid program currently constitutes 32% of the state budget and provides insurance coverage to 18% of the state’s population. At the same time, 13% of North Carolinians remain uninsured, and even among the insured, significant health disparities persist across income, geography, education, and race. The Duke University Bass Connections Medicaid Reform project gathered to consider how North Carolina could use its limited Medicaid dollars more effectively to reduce the incidence of poor health, improve access to healthcare, and reduce budgetary pressures on the state’s taxpayers. This report is submitted to North Carolina’s policymakers and citizens. It assesses the current Medicaid landscape in North Carolina, and it offers recommendations to North Carolina policymakers concerning: (1) the construction of Medicaid Managed Care markets, (2) the potential and dangers of instituting consumer-driven financial incentives in Medicaid benefits, (3) special hotspotting strategies to address the needs and escalating costs of Medicaid\u27s high-utilizers and dual-eligibles, (4) the emerging benefits of pursuing telemedicine and associated reforms to reimbursement, regulation, and Graduate Medical Education programs that could fuel telemedicine solutions to improve access and delivery.

Cost-benefit analysis and valuation uncertainty

This thesis addresses the economic trade-offs between hydropower and fish production, based on an empirical assessment of the costs and benefits of changing the water flow of the Ume/Vindel River in northern Sweden at a major hydropower plant in ways that would reduce its production of electricity but increase the number of wild salmon in the river. A theoretical framework for dynamic cost benefit analysis (CBA) is presented and applied to the salmon passage-hydropower production conflict. The approach has wider applicability than suggested here, and should be useful in other, similar contexts. To obtain estimates for the benefit of increasing the number of wild salmon the contingent valuation method (CVM) was applied. The CVM is a survey-based method developed for measuring values of non-market goods by using willingness to pay (WTP) questions. A new open-ended valuation question, the “classic and interval open-ended” (CIOE) question, was introduced to accommodate the fact that many people have an inability to state their preferences accurately. Interpretation of the resulting valuation uncertainty is more straightforward with this type of question than with other types of valuation question. There are other advantages as well. In addition, methods are introduced for: finding a WTP point estimate for the CIOE question; estimating lower and upper boundaries for the WTP; and for estimating confidence intervals for the total present benefit. An important element of the empirical analysis is that estimated changes in resource conditions are based on detailed river-specific data. The resource dynamic considerations were introduced into both the scenarios and the WTP questions, using an estimated salmon population model for the Vindel River as a base. A model predicting the effects of varying the water flows on the salmon’s migration behaviour was used to estimate the costs of increasing the number of salmon. A total of 1785 individuals received a questionnaire including the CIOE question; the response rate was 66%. Passive use (non-use) values are the major contributors to the benefit (96-517 MSEK) of increasing the wild salmon stock in the Vindel River. The sensitivity analysis suggests that the opportunity costs in terms of lost electricity are typically higher than the estimated benefits
