This paper uses laboratory experiments to study subjects' assessment of uncertainty resulting from strategic and non-strategic decisions of other players. Nonstrategic events are defined by the colors of balls drawn from urns, whereas strategic events are defined by the action choice in Stag...

We conduct a replication experiment, with sophisticated student participants, of the three main treatments of the debt aversion experiment by Martínez-Marquina and Shi (2024). While participants in our experiment have chosen return maximizing strategies much more frequently than those in...

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 largescale (partly) incentivized online surveys of students at a Japanese university and of a sample of...

We investigate how individuals use measures of apparent predictability from price charts to predict future market prices. Subjects in our experiment predict both random walk times series, as in the seminal work by Bloomfield & Hales (2002) (BH), and stock price time series. We successfully...

Previous research consistently identified differences in time preferences between effort and monetary decisions. However, the root cause of this difference- whether it stemmed from the intrinsic nature of the outcomes or the associated pleasurable or unpleasurable experiences-remained undefined....

The delay effect, that people discount the near future more than the distant future, has not been verified rigorously. An experiment conducted by us in China confirms that, by separating the delay from the interval, the delay effect exists only within a short delay. The results are reliable,...

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

This study uses a Japanese nationwide sample and experimentally compares rebate and matching, both of which are schemes intended to lower the price of monetary donation. Standard economic theory predicts that the two schemes will have the same effect on individuals' donation behavior when their...

In the digital age, privacy in economic activities is increasingly threatened. In considering policies to address this threat, it is useful to consider what value, if any, that people attach to privacy in economic activities. We study this question by eliciting individuals' willingness to pay...
