摘要：Whether preferences are independent of entitlements has received vigorous attention in recent years. This skepticism was triggered by laboratory experiments which reported that undergraduate students exchanged their endowments less frequently for similar goods of roughly equal value (Knetsch 1989; Kahneman, Knetsch, and Thaler 1990). This was interpreted as evidence in favour of psychological influences on exchange behavior broadly known as “prospect theory”. Others examined the robustness of these laboratory findings in alternate environments; while List (2003, 2004) studied exchange behavior in field environments, Engelmann and Hollard ( 2010) and Plott and Zeiler (2005, 2007 and 2010) focussed on the role of experimental procedures. Their findings suggest that differences in valuation resulting from ownership could become weaker or disappear as (i) more experience is accumulated in field or (ii) with greater familiarity with experimental procedures employed in the laboratory. In this paper I explore an alternative which could influence behavior in lab environments. The experiment explores whether apprehension associated with exchange decisions affects behavior of typical participants in laboratory conditions. The experiment combines the insights from extensions of the simple barter trading which suggest a weaker endowment effect due to greater familiarity with the trading task, changes in experimental procedures and/or better experience in field environment. If these effects are significant, does an environment that provides control against potential mistakes weaken the psychological influences on exchange behavior in laboratory? I explore an extension of the barter exchange experiments in the laboratory and discuss some preliminary results.
