The share of immigrants in the German social assistance program exceeds their population share and continues to grow. This study evaluates the causes of this phenomenon and tests for the effects of assimilation, cohort, age at migration, and country of origin on immigrant behaviour. It uses...

The single most likely way to leave the unemployment insurance (UI) register in Hungary is not by getting a job but by exhausting entitlement to benefit. Two questions follow. First, what are the implications of the cessation of UI for living standards? Second, does UI exhaustion have much...

Falling output and living standards have pushed countries in transition from the socialist system to re-consider how best to target public resources on those in need. The paper investigates the workings of a new social assistance benefit in Uzbekistan, the largest of the former Soviet Central...

Efficient measures are often not implemented because of their potentially damaging effects on distribution, yet these distributional effects are scarcely studied in economics because of the idea that they are case specific. In this paper we show that when we can separate the effect on efficiency...

It is well known that ex post efficient mechanisms for the provision of indivisible public goods are not interim individually rational. However, the corresponding literature assumes that agents who veto a mechanism can enforce a situation in which the public good is never provided. This paper...

Recent empirical studies criticize the sluggish financial integration in the euro area and find that only interbank money markets are fully integrated so far. This paper studies the optimal regional and/or sectoral integration of financial systems given that integration is restricted to the...

We investigate how the assumption that individuals are characterized by some recent forms of behavioural preferences changes the analysis of an otherwise classical welfare problem, namely the optimal allocation of a scarce resource among a finite number of claimants. We consider two preference...

This paper studies equilibria for economies characterized by moral hazard (hidden action), in which the set of contracts marketed in equilibrium is determined by the interaction of financial intermediaries. The crucial aspect of the environment that we study is that intermediaries are restricted...

The condition for when a price control increases consumer welfare in perfect competition is tighter than often realised. When demand is linear, a small restriction on price only increases consumer surplus if the elasticity of demand exceeds the elasticity of supply; with log-linear or...

This paper studies the implications of cross-border financial integration for financial stability when banks' loan portfolios adjust endogenously. Banks can be subject to sectoral and aggregate domestic shocks. After integration they can share these risks in a complete interbank market. When...
