This paper addresses the question how the expectation of unconditional external shocks like foreign aid increase or decrease saving and, thus, accelerate or delay macroeconomic stabilizations. We build on Casella and Eichengreen (1996) who first used Alesina and Drazen's (1991) war-of-attrition...

We study experiments of an overlapping generations model where inflation is determined by the monetary policy and by the amount of average saving within each period. We use a new experimental setup that allows us to observe more details of the process of formation of expectations and separate...

If migrants return to their origin countries, two questions arise which are of immediate economic interest for both immigration and emigration country: What determines their optimal migration duration, and what are the activities migrants choose after a return. Little research has been devoted...

Experiments with first price auctions find typically a substantial amount of overbidding which is often related to risk aversion. If this could be generalised then first-price auctions should generate a higher revenue then second-price auctions. We show that at least part of this overbidding is...

We introduce and experimentally test an auction model that allows for outside options of bidders as substitutes for the auctioned object under the private values assumption. Theoretically and in the experiments, bidders respond to their individual outside options and to variations of common...

We study with the help of experiments a two-player second-price all-pay auction. Such an auction describes e.g. the situation of a country were stabilisations are achieved through tax increases that eliminate a budget deficit. If these tax increases have distributional implications then...

In this paper we study learning and cooperation in repeated prisoners' dilemmas experiments. We compare interaction neighbourhoods of different sizes and structure and we observe choices under different information conditions and estimate parameters of a learning model. We test robustness of the...

To understand the effect of fiscal policy on the private sector we have to comprehend how expectations about fiscal variables are formed. However, little is known about the way people form expectations about fiscal variables: no undercutting theory exists, not to say empirical evidence. The...

We study experiments in an auction setting with interdependent valuation. Groups of three players receive private signals and then bid for a single, indivisible item. Valuations for the item differ within groups and depend asymmetrically on a bidder's own and other bidders' signals....

This study disentangles experimentally imitation, reinforcement, and reciprocity in repeated prisoners' dilemmas. We compare a simple situation in which players interact only with their neighbours (local interaction) with one where players interact with all members of the population (group...
