Multiple Cournot oligopoly experiments found more collusive behavior in markets with fewer firms (Huck et al., 2004; Hostmann et al., 2018). This result could be explained by a higher difficulty to coordinate or by lower incentives to collude in markets with more firms. We show that the Quantal...

The random Incentive System (RIS) is a standard method to incentivize participants in economic experiments. However, recent theoretical studies point out the possibility of its failure under ambiguity. We propose a modification of RIS, named independent RIS (I-RIS), to improve its reliability....

This study experimentally evaluates the performance of partial equilibrium mechanisms when different sectors run their mechanisms separately, despite the existence of complementarity between them.In our simple laboratory experiment setting that includes two sectors, each sector runs the...

In this paper, we reexamine a bias revealed by Kunz et al. (2017) regarding structured financial products known as barrier reverse convertibles (BRCs) with worst-of payout characteristics. Namely, using a nonincentivized survey of investor risk perceptions, Kunz et al. (2017) found that when...

We summarize the experimentally measured characteristics of the registered participants of the experiments conducted at the Institute of Social and Economic Research, Osaka University. Measured characteristics include fluid intelligence, risk preference (risk aversion, prudence, and temperance),...

We experimentally investigate the effect of a central bank buying bonds for cash in a quantitative easing (QE) operation. In our experiment, the bonds are perfect substitutes for cash and have a constant fundamental value which is not affected by QE in the rational expectations equilibrium. We...

We compare the performance of financial professionals (CFAs) with university students in four financial forecasting tasks ranging from simple lab prediction tasks to longitudinal field tasks. Although students and professionals performed similarly in the artificial forecasting tasks, their...

We address a concern about the external validity, in particular, the representativeness of the sampled population, of an experiment conducted with university students. We do so by conducting large-scale (partly) incentivized online surveys of students at a Japanese university and of a sample of...

Common sense is a dynamic concept and it is natural that our (statistical) common sense lags behind the development of statistical science. What is not so easy to understand is why common sense lags behind as much as it does. We conduct a survey among Japanese students and try to understand why...

In this paper we experimentally compare three implementations of Winter demand commitment bargaining mechanism: a one-period implementation, a two-period implementation with low and with high delay costs. Despite the different theoretical predictions, our results show that the three different...
