Eliciting Willingness to Pay without Bias using Follow-up Certainty Statements: Comparisons between Probably/Definitely and a 10-point Certainty Scale

Correction for hypothetical bias using follow up certainty questions often takes one of two forms: (1) two options, “definitely sure” and “probably sure”, or (2) a 10-point scale with 10 very certain. While both have been successful in eliminating hypothetical bias from estimates of WTP by calibrating based on the certainty of yes responses, little is known about the relationship between the two. The purpose of this paper is to compare the two using data from three field experiments in a private good, dichotomous choice format. We compare four types of yes responses that differ in the criterion used to determine if there is sufficient certainty for a hypothetical yes response to be considered a true yes response. We make several comparisons, but focus on determining which values on the 10-point scale give the same estimates of WTP as “definitely sure” hypothetical yeses and real yeses (actual purchases). Values that produce equivalence are near 10 on the certainty scale.     

“You Can't Make a Good Wine without a Few Beers”: Gatekeepers and knowledge flow in industrial districts

Knowledge sharing sometimes plays a key role in the performance of clustered organizations, particularly small and medium-sized enterprises (SMEs), however, SMEs also face significant knowledge-related disadvantages due to their lack of absorptive capacity and functional expertise. This study investigates the influence of technical specialists on knowledge flow in a wine cluster in Australia. The main contribution of this paper is a finding that the technical specialist's gatekeeping role both links clustered SMEs to the global wine “systemworld” by transferring knowledge of technical developments and innovation, and simultaneously develops and refines regional winemaking styles by sharing locally specific, experientially derived knowledge. Technical specialists drew on bridging and bonding social capital to identify and retrieve specialist knowledge, and were capable of assimilating complex technical knowledge into the cluster. These findings are particularly significant because recipients were typically small and micro-firms, which are frequently located outside cluster knowledge-network.     

Economic Reform and Labor Unions: A General-Equilibrium Analysis Applied to Bangladesh and Indonesia

Noting the trend toward more independent trade unions in developingcountries, this article examines whether the presence of unionsstrengthens or weakens the benefits to be gained from economicpolicy reform. We show that the presence of "passive" unions—onesthat choose their wage-employment contract given the firm'scost-minimizing strategy—increases the welfare gains fromtrade liberalization, because trade reform lowers the wage premiumenjoyed by the unionized sector, reducing a distortion in thelabor market. These gains are amplified when the unions are"active", namely, when they negotiate a contract with the firmthat is off its labor demand curve. Such a contract resultsin featherbedding—paying workers more than their marginalproduct—and trade reform reduces the amount of featherbedding.The policy implication for Bangladesh—a country with strongtrade unions and a protected unionized sector—is thatthe benefits of further trade liberalization may be greaterthan otherwise predicted. In Indonesia, where both unionizationand import tariffs are low, allowing greater independence tounions may preserve flexibility and reward workers better thanthe current minimum-wage policy.     

Small sample behaviour of some nonparametric multi-sample location tests in the presence of dispersion differences

This paper describes the small and moderate sample behaviour of three studentized non-parametric statistics by Sen and a modified Wilcoxon statistic by Potthoff for testing the equality of location parameters in the presence of dispersion differences. Based on the agreement between the asymptotic and small sample distributions of the statistics as well as a comparison of their power under heteroscedasticity, the studentized Wilcoxon and the studentized Brown and Mood tests arc preferred in the two-sample and c-sample situations, respectively.     

Registered nurses' perspectives on health care and the 2008 presidential election

As this historic presidential election draws near, what do RNs think of our nation's priorities? Which candidates do they think will be most effective in shaping our health care system and addressing the most pressing issues of our time? The results of this survey show that RNs do not identify overwhelmingly with one political ideology or party and, in fact, they closely resemble the public on these political dimensions. The data also show that RNs identify health care issues as the most important problem facing the nation. RNs who believe that it is the responsibility of the government to provide health insurance to those without it, have more confidence in the government to achieve this outcome, and are more likely to be Democrats than Republicans. The presidential election is expected to be highly contested and could be determined by a relatively small margin of votes and, thus, nurses should recognize their chances of influencing the outcome of the election. The data from this survey provide baseline information potentially useful to increasing the political influence of the nursing profession, informing other organizations about where they might align with nurses, and helping candidates and the political parties compete more effectively in seeking the support of roughly 3 million RN voters.     

An outcome-based assessment of international transfer pricing policy

Instead of concentrating on the selection of the optimal transfer pricing method, this paper focuses on the consequences of international transfer pricing for multinational entities. A sample of U.S.-based multinational firms is employed to determine if transfer pricing results in measurable financial outcomes. Results of the study indicate that firms employ international transfer pricing to meet a variety of objectives. The dollar value of international transfers and the foreign sales percentage are both significant explanatory variables for the financial outcomes of these objectives.     

An alternative interpretation of the discontinuity in earnings distributions

We show that the asymmetric effects of income taxes and special items for profit and loss firms contribute to a discontinuity at zero in the distribution of earnings. Income taxes draw profit observations towards zero while negative special items pull loss observations away from zero. These earnings components are thus expected to contribute to a discontinuity even in the absence of discretion. We show our results are not an artifact of deflation and that other common components of earnings do not have similar effects on the earnings distribution around zero.
