Dealing with Internal Inconsistency in Double-Bounded Dichotomous Choice: An Application to Community-Based Health Insurance

Contingent valuation method is commonly used in the field of health economics in an attempt to help policy maker in taking decisions. The use of the double-bounded dichotomous choice format results in a substantial gain in statistical efficiency over the single bounded dichotomous choice format. Yet, this efficiency gain comes at the cost of biasness known as internal inconsistency. This paper aims at reducing this internal inconsistency in double-bounded dichotomous choice by using the certainty calibration technique in a community-based health insurance study. Findings confirm the internal inconsistency between the initial and the follow-up responses and the statistical efficiency gains of the double-bounded dichotomous choice over the single-bounded dichotomous choice. Furthermore, the use of certainty calibration reduces this internal inconsistent pattern in responses and still maintains efficiency gain. We further discuss the policy implications.Contingent valuation; internal inconsistency; certainty calibration; community-based health insurance

Contingent valuation versus choice experiments: a meta-analysis application exploring the determinants of the time for publication acceptance

In this paper, we test whether the time it takes for a submitted paper to be accepted by the editor(s) is sensitive to the stated preference method used. Two methods are considered: the Contingent Valuation (CV) and the Choice Experiments (CE). A meta-analysis based on a sample of 129 papers published in Resource and Energy Economics, Ecological Economics and Environmental and Resource Economics between 2005 and 2011 is conducted. The dependent variable in the ordinary least squares regression model is the number of days between the submission of the paper and the acceptance of the paper, referred to as Time for Publication Acceptance, or TPA. The main results are that TPA is lower for CE papers than CV papers, especially for those that aim at improving the method which can be interpreted as a higher academic demand in the CE field. However, a convergence is observed over the years
