Idiosyncratic Risk, Aggregate Risk, and the Welfare Effects of Social Security
(2017-12-01)
We ask whether a pay-as-you-go financed social security system is welfare improving in an economy with idiosyncratic productivity and aggregate business cycle risk. We show analytically that the whole welfare benefit from ...
A Repeated Principal-Agent Model with On-the-Job Search
(2014-08-01)
This paper analyzes how on-the-job search (OJS) by an agent impacts the moral hazard problem in a repeated principal-agent relationship. OJS is found to constitute a source of agency costs because efficient search incentives ...
Incompatible European Partners? Cultural Predispositions and Household Financial Behavior
(2015-01-27)
The Eurozone fiscal crisis has created pressure for institutional harmonization, but skeptics argue that cultural predispositions can prevent convergence in behavior. Our paper derives a robust cultural classification of ...
Direct and Indirect Risk-Taking Incentives of Inside Debt
(2016-07-16)
We develop a model of managerial compensation structure and asset risk choice. The model provides predictions about the relation between credit spreads and different compensation components. First, we show that credit ...
The Effects of a Low Interest Rate Environment on Life Insurers
(2015-01-01)
Low interest rates are becoming a threat to the stability of the life insurance industry, especially in countries such as Germany, where products with relatively high guaranteed returns sold in the past still represent a ...

How Special Are They? – Targeting Systemic Risk by Regulating Shadow Banking
(2014-10-05)
This essay argues that at least some of the financial stability concerns associated with shadow banking can be addressed by an approach to financial regulation that imports its functional foundations more vigorously into ...
A Life-Cycle Model with Ambiguous Survival Beliefs
(2015-10-02)
Based on a cognitive notion of neo-additive capacities reflecting likelihood insensitivity with respect to survival chances, we construct a Choquet Bayesian learning model over the life-cycle that generates a motivational ...
Peer Effects and Risk Sharing in Experimental Asset Markets
(2015-02-02)
Previous research has documented strong peer effects in risk taking, but little is known about how such social influences affect market outcomes. Since the consequences of social interactions are hard to isolate in financial ...
Social Security in an Analytically Tractable Overlapping Generations Model with Aggregate and Idiosyncratic Risk
(2015-04-13)
When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations. We derive the ...
