In a commonvalueauction in which the information partitions of the bidders are connected, all rings are core-stable. More precisely, the ex ante expected utilities of rings, at the (noncooperative) sophisticated equilibrium proposed by Einy et al. [Einy, E., Haimanko, O., Orzach, R., Sela, A.,...

We propose a semi-cooperative game theoretic approach to check whether a given coalition is stable in a Bayesian game with independent private values. The ex ante expected utilities of coalitions, at an incentive compatible (noncooperative) coalitional equilibrium, describe a (cooperative)...

The paper focuses on the signaling value of a tax when agents are less informed than the government on the effect of their consumption. The policy making process is analyzed as a game in which the government wants to influence consumers' behaviors through tax policy, consumers being rational and...

This paper argues that random audit programs provide income taxpayers with information that alters their perceptions of, and hence their behavioral responses to, audits. Comparing samples of randomly selected audited and non-audited UK taxpayers, the evidence confirms predictions that audited...

Globalization probably had less impact on regional inequalities than fiscal distortions

In this paper we focus on the effects of investigations on tax compliance. Results from empirical studies suggest that the effects of audits are not only in terms of recovered unpaid tax (direct effects), but there are also indirect effects in terms of future better compliance in the rest of the...

We study the impact of crossholdings on the efficiency of the standard auction formats. The ascending auction is not equivalent to the second-price auction. In a class of examples, the ascending auction is the only efficient standard auction format.

This paper examines how shareholdings affect auctions' revenue and efficiency with independent private values. Two types of shareholdings are analyzed: vertical (resp: horizontal) toeholds cover situations in which bidders own a fraction of the seller's profit (resp: a share of their...
