We analyze the impact of risk and ambiguity aversion using a lifecycle recursive utility model. Both risk and ambiguity aversion are shown to reduce annuity demand and enhance bond holdings. We obtain this result using an intertemporal framework in which we can vary both risk and ambiguity...

We study a decision-maker who selects, in every fixed period of time, T times from every collection of feasible alternatives, where T is pre-determined by him. We axiomatize the class of T-choice functions according to which the decision-maker has fixed preference relation along the same period...

We study how investors' preferences for robustness influence corporate investment, financing, and compensation decisions and valuation in a financial contracting model with agency. We characterize the robust contract and show that early liquidation can be optimal when investors are sufficiently...

This is an open source monograph about the economics of teams and the collection of intelligence in an espionage, counter-intelligence context. Our focus is decision-making, including search processes, under ambiguity or true uncertainty and the way that idiosyncratic human reactions to...

We provide empirical evidence that visceral factors affect financial risk taking by showing that exposure to mass shootings alters mutual fund managers' risk taking decisions. Funds that are exposed to mass shootings subsequently decrease risk relative to their peers. The effect that we document...

An agent decides whether to approve a project based on his information, some of which is verified by a court. An honest agent wants to implement projects that are likely to succeed; a dishonest agent wants to implement any project. If the project fails, the court examines the verifiable information...

It has long been recognized in finance and other literature that variance provides option value. The same point carries over to the labor market. Firms like variance in new employees because they can keep the good workers and terminate the bad ones. But market wages must adjust to make the...

This paper focuses on the 2008 to 2020 period during which two major crises, affecting the economy and the financial markets, occurred. Between 2008 and 2020, there were less extreme tail events, including the lingering Eurozone and Greece crises. In particular, after extremely high stock market...

Economists have become increasingly interested in using attention to explain behavioral patterns both on the micro and macro level. This has resulted in several disparate theoretical approaches. Some, like rational inattention, assume a “top-down” model of executive optimization. Others,...

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....
