Meyerheim, Gerrit - 2026 - Original Version: October 2025, This Version: March 2026

This paper develops a tractable consumption-based asset-pricing model in an i.i.d. economy that combines rare consumption disasters with ambiguity aversion implemented as a one-period entropic tilt under CRRA utility. Closed-form expressions for the risk-free rate, equity return moments, and the...

Fat-tailed distribution under the smooth ambiguity model

Osei, Prince - 2026

We study the ambiguity-adjusted return distribution induced by an investor with smooth ambiguity preferences 'a la Klibano! et al. (2005), who faces uncertainty about the variance of asset returns. The variance uncertainty is modeled using a gamma distribution, a second-order prior over the...

Symmetric expected utility

Preker, Jurek - 2026

We investigate and axiomatize preferences that display indifference between deterministic states, but exhibit strict orderings over lotteries over these states. Such preferences might be due to the ability to adopt to states, or a (dis)taste for uncertainty. We derive a representation theorem...

Risk aversion, self-control, commitment savings device and benchmark-defined undersaving among nano enterprises in urban slums : a logistic regression approach

Osifodunrin, Edward A.; Lopes, José Dias - 2026

Low-income individuals are unlikely to save relatively large sums on a regular basis; however, many still fall short of even the modest threshold required for long-term financial security. This study examines the determinants of benchmark-defined undersaving among retail e-payment agents (REAs)...

Retirement under policy uncertainty

Bello, Piera; Galasso, Vincenzo; Izzo, Alessandro - 2026

This paper examines how policy uncertainty influences retirement decisions. We develop a simple model in which individuals face a one-time choice between immediate retirement and continued employment until the statutory retirement age. In the absence of policy uncertainty, retirement decisions...
