In this paper we analyse several measures which are typically included in a social security reform: a cut in the social security benefits, an increase in the social security tax and tax incentives for the purchase of private life annuities, which have recently become quite popular at the...

This paper investigates the effect of adverse selection on the private annuity market in a model with two periods of retirement. In order to introduce the existence of limited-time pension insurance, we assume that for each period of retirement separate contracts can be purchased. Demand for the...

This paper investigates the effect of adverse selection and price competition on the private annuity market in a model with two retirement periods. In this framework annuity companies can offer contracts with different payoffs over the periods of retirement. Varying the time structure of the...

The market for private life annuities is characterised by adverse selection, that is, contracts offer lower than fair payoffs to individuals with low life expectancy. Moreover, life expectancy and income have been found to be positively correlated. The paper shows that a linear tax on annuity...

This paper includes couples on the demand side and analyses their implications on the problem of adverse selection in the annuity market. First, we examine the pooling equilibrium for individual-life annuities and show that in the presence of couples the rate of return on individuallife...

We examine equilibria in competitive insurance markets with adverse selection when wealth differences arise endogenously from unobservable savings or labor supply decisions. The endogeneity of wealth implies that high risk individuals may ceteris paribus exhibit the lower marginal willingness to...

Health insurance is potentially subject to risk selection, i.e. adverse selection on the part of consumers and cream skimming on the part of insurers. Adverse selection models predict that competitive health insurers can eschew high-risk individuals by offering contracts with low deductibles or...

Charness and Dufwenberg (American Economic Review, June 2011, 1211-1237) have recently demonstrated that cheap-talk communication raises efficiency in bilateral contracting situations with adverse selection. We replicate their finding and check its robustness by introducing competition between...

When premiums are community-rated, risk adjustment (RA) serves to mitigate competitive insurers'; incentive to select favorable risks. However, unless fully prospective, it also undermines their incentives for efficiency. By capping its volume, one may try to counteract this tendency, exposing...

This paper contributes to the ongoing discussion on price formation in electricity markets. For this, we conduct an analysis of the German electricity wholesale spot market which is located at the European Energy Exchange (EEX). Our dataset covers three spot market segments, namely the intraday...
