報告摘要：

Economic normative models assume that economic actors are fully rational and selfish while recent studies acknowledge the emotional influence of an economic decision and call for further investigation of biases in decision making. Most decisions involve multiple actors who make decisions following a sequential path as reflected by decision trees; this contingency makes a call for the game theory contribution in the economic decision field. Two-person games are widely used to represent a typical framework of economic decisions. This study aims at further investigating psychological biases affecting decisions in a two-person sequential game. So far similar studies have focused on the principal (or first mover) behavior without paying much attention to the second mover. We aim to unveil how reciprocating propensity and inequity aversion issues influence the second mover’s decision. We designed and conducted a series of laboratory experiments to let just one of the potential biases act in each part of each treatment. This experiment design allows for examining the hypothesized hierarchical level of intervention by reciprocity and inequality aversion. Experimental results support the dominance of inequality aversion as the main driver in reciprocal behavior and suggest a refinement of the idea of a triggering hierarchy of decision biases.
