Assuming that an individual's rank in the wealth distribution is the only factor determining the individual's wellbeing, we analyze the individual's risk preferences in relation to gaining or losing rank, rather than the individual's risk preferences towards gaining or losing absolute wealth. We...

After the publication of Keynes' "General Theory," economics was frequently described as schizophrenia: (neo-) classical at the micro-level, but Keynesian at the macro-level. In actuality, Keynes' revolution was, to a substantial part, based on the behavioral micro-foundations of the world we...

Keynes' General Theory (GT) ist in zweierlei Hinsicht umfassender als das (neo-) klassische Modell: (1) sie schließt das Vollbeschäftigungsgleichgewicht als Sonderfall ein und (2) sie basiert auf realistischem mikroökonomischem Verhalten, dessen sozial isolierter, den Eigennutz maximierender...

Since at least de Finetti [7], preference symmetry assumptions have played an important role in models of decision making under uncertainty. In the current paper, we explore (1) the relationship between the symmetry assumption of Klibanoff, Mukerji and Seo (KMS) [21] and alternative symmetry...

During recent decades, many new models have emerged in pure and applied economic theory according between Epstein (2010) and Klibanoff et al. (2012) identified a notable behavioral issue that distinguishes sharply between two classes of models of ambiguity sensitivity that are importantly...

We show that the disposition to focus on favorable or unfavorable outcomes of risky situations affects willingness to take risk as measured by the general risk question. We demonstrate that this disposition, which we call risk conception, is strongly associated with optimism, a stable facet of...

We propose a new measure of deviations from expected utility, given data on economic choices under risk and uncertainty. In a revealed preference setup, and given a positive number e, we provide a characterization of the datasets whose deviation (in beliefs, utility, or perceived prices) is...

Most economic decisions are embedded in a specific social context. In many such contexts, individual choices are influenced by their observability due to underlying social norms and social image concerns. This study investigates the impact of choices being observed, compared to anonymity of...

We investigate the trade-off between the opportunity costs of decisions and their quality in a simple model. In a lab experiment, we introduce exogenous variation in the opportunity costs of time. Contrary to claims in the previous literature, we show that using more time when making small-stake...
