Hypothetical bias is a long‐standing issue in stated preference and contingent valuation studies—people tend to overstate their preferences when they do not experience the real monetary consequences of their decision. This view, however, has been challenged by recent evidence based on the elicitation of induced values (IV) in the lab and homegrown (HG) demand function from different countries. This paper uses an experimental design to assess the extent and relevance of hypothetical bias in demand elicitation exercises for both induced (IV) and homegrown (HG) values. For testbed purpose, we use a classic second‐price auction to elicit preferences. Comparing the demand curve we elicit in both, hypothetical bias unambiguously (i) vanishes in an IV, private good context and (ii) persists in HG values elicitation context. This suggests hypothetical bias in preference elicitation appears to be driven by “preference formation” rather than “preference elicitation.” In addition, companion treatments highlight two sources of the discrepancy observed in the HG setting: the hypothetical context leads bidders to underestimate the constraints imposed by their budget limitations, whereas the real context creates pressure leading them to bid “zero” to opt out from the elicitation mechanism. As a result, there is a need for a demand elicitation procedure that helps subjects take the valuation exercise sincerely, but without putting extra pressure on them. 相似文献

U.S. stocks are more volatile than stocks of similar foreign firms. A firm's stock return volatility can be higher for reasons that contribute positively (good volatility) or negatively (bad volatility) to shareholder wealth and economic growth. We find that the volatility of U.S. firms is higher mostly because of good volatility. Specifically, stock volatility is higher in the United States because it increases with investor protection, stock market development, new patents, and firm‐level investment in R&D. Each of these factors is related to better growth opportunities for firms and better ability to take advantage of these opportunities. 相似文献

Whereas prior research has focused on consumer socialisation and intergenerational influence theories to study mother–daughter interactions, this research draws on identity to emphasise the association between mothers’ social comparison and their related clothing consumption behaviors in the presence of adolescent daughters. A survey of 423 adolescent daughters’ mothers shows how personal and relational identities combine to favor mothers’ social comparison process with their adolescent daughter and explain a set of consumption behaviors, including co-consumption practices (common shopping, joint purchases, clothing exchanges) and mothers’ changes in brands, stores and styles. In order to better target adolescent girls’ mothers, retailers could develop more inter-generational practices. 相似文献

This paper provides an approach to the measurement of the “scale effects” in the allocative profit efficiency. To be specific, we evaluate the improvements of profit that can be accomplished by means of a change in the scale size, once technical efficiency is achieved. New decompositions of the allocative efficiency into a scale effect component and the corresponding residual mix effect component are derived. 相似文献

This note reinforces the results in a paper by Sen (International Journal of Industrial Organization, vol. 11, 1993, pp. 123–37). It is shown that his assumption that the incentive schemes in a two‐period model are the same for the two periods is not necessary for the results: only the long‐term nature of contracts with managers matters. 相似文献
