Providing public goods is hard, because providers are best off free-riding. Is it even harder if one group's public good is a public bad for another group or, conversely, gives the latter a windfall profit? We experimentally study public goods provision embedded in a social context and find that...

Rothschild and Stiglitz (1976) show that there need not exist a competitive equilibrium in markets with adverse selection. Building on their framework we demonstrate that externalities between agents - an agent's utility upon accepting a contract depends on the average type attracted by the...

This paper examines the concept of global public goods (GPGs) and in that context explores the extent of aid (ODA) presently being diverted to GPG provision and whether such diversion skews aid-flows towards some recipients and whether diverting aid to GPG provision crowds out aid for...

Die vorliegende Arbeit liefert über eine agency-theoretische Analyse für alternative Produktmarktbedingungen Erkenntnisse zu den Eigenschaften optimaler linearer Anreizsysteme auf Basis einer relativen Performancebewertung im duopolistischen Wettbewerb. Gegenstand der Analyse ist insbesondere...

Healthcare payment systems influence to a great extent the hospitals' investment decision and thereby, their ability to treat patients. A payment system is optimal provided it incentivises hospitals to undertake an investment level that is appropriate, when considering treatment costs, patients'...

Urban traffic congestion is recognised as a major problem by most people in world cities. However, theimplementation of congestion reducing measures on a wide scale eludes most world cities suffering fromtraffic congestion, as many oppose the notion of road pricing and despite economists and...

In this paper, a dynamic general equilibrium (DGE) model of growth–inequality relationships, with missing credit markets, knowledge spillover and self-employed agents, is calibrated to New Zealand data. The model explains how two distinct policy shocks involving redistribution and immigration...
