D03 - Behavioral Microeconomics: Underlying PrinciplesReturn

In this paper I explain individual propensity to herding behaviour and its relationship to time-pressure by conducting a laboratory experiment. I let subjects perform a simple cognitive task with the possibility to herd under different levels of time pressure. In the main treatments, subjects had a chance to revise their decision after seeing decisions of others, which I take as an indicator of herding behaviour. The main findings are that the propensity to herd was not significantly influenced by different levels of time pressure, although there could be an indirect effect through other variables, such as the time subjects spent revising the decision. Heart-rate significantly increased over the baseline during the performance of a task and its correlation to the subjectively stated level of stress was positive but very weak, which suggests that time pressure may not automatically induce stress but increase effort instead.

This paper discusses the electoral implications of psychological motivation on voting functions. We tested a claim of the Weber-Fechner law as applied to electoral behaviour - specifically, that an expanded public sector leads politicians to make more significant, opportunistic distortions of public expenditures than the distortions observed when the public sector is diminished. We employed a system of simultaneous equations to test this hypothesis for cases observed in more than sixty democracies since 1960. We gave a special focus to the cases of Central and Eastern European countries. Our results confirm the main implications of the Weber-Fechner law. Years in incumbency, running for re-election, higher unemployment and higher inflation rates tend to generate negative moods, feelings and affects in the electorate; thus, these factors tend to approximate the vote share of the most voted party to the remaining vote share of the challenger political forces.
