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...

Asymmetric fertility elasticities

Numerical methods to value an option including risk aversion with a constant relative risk aversion function

This study develops a comprehensive discrete numerical model for option valuation that explicitly incorporates risk preferences, which may deviate from risk neutrality. Unlike the traditional binomial tree models - strictly under the risk-neutral paradigm - our framework embeds a constant...

Ambiguity and the value of late resolution of uncertainty

Kochov, Asen - 2026

The paper shows that in a dynamic setting with multiple sources of uncertainty, recursive ambiguity-averse preferences may imply a preference for late resolution of uncertainty. In particular, the simultaneous resolution of two sources can offer hedging benefits that are negated when one source...

Optimal design of model-contingent insurance contracts

Riedel, Frank; Spengemann, Marco - 2026

We study optimal insurance design under linear transaction costs for a policyholder with smooth ambiguity preferences when the underlying loss distribution is identifiable ex post. Under expected utility, Arrow's classical theorem implies that the optimal contract is a straight deductible. Under...
