As a selling mechanism, auctions have acquired a central position in the free market economy all over the globe. This development has deepened, broadened, and expanded the theory of auctions in new directions. This chapter is intended as a selective update of some of the developments and...

I introduce a property of player's valuations that ensures the existence of an ex post efficient equilibrium in asymmetric English auctions. The use of this property has the advantage of yielding an ex post efficient equilibrium without assuming differentiability of valuations or that signals...

We provide a comparison of bidding behavior between multi-round and single-round auctions considering bid lettings for asphalt construction contracts. Using a reduced-form difference-in-difference approach as well as the nonparametric estimation technique proposed by Racine and Li (2004) we find...

This paper gives two examples to break through the revelation principle. Furthermore, the revenue equivalence theorem does not hold.

Ken Arrow (1998) asks, “What has economics to say about racial discrimination?” He replies – entirely correctly – that racial “segregation within an industry – that is, firms with either all black or all white labor forces” – may be explained by economic theory, but “the...

Physical resources such as land, labour and livestock, and nonphysical resources such as indigenous knowledge and institutions of producers in the grain surplus and deficit regions of the Central Highlands of Ethiopia are examined under situation of environmental and policy risks. Frequency...

We study abstention when each voter selects the quality of information. We introduce conflict among committee members using two dimensions of heterogeneity: ideology (relative ratio of utilities) and concern or intensity (absolute level of utility). Our main result is that information and...

In a scenario with a continuum of asymmetrically informed agents, we analyze how the initial information of a trader may be altered when she becomes a member of a coalition. In contrast to a perfect competition frame, we first show that neither arbitrarily small coalitions nor large coalitions...

This review article introduces and evaluates various ways to aggregate probabilistic opinions of different individuals. For each of these three ways, an axiomatic characterization result is presented (a new one in the case of multiplicative pooling). The three ways satisfy different axioms and...

In this brief comment, the public choice theory aims to distinguish the dilemmas and conflicts in formal and empirical. The hypothesis argues that the reality more complex than the principles of choice of Pareto and Liberalism*. Both the ethics and politics are taking decisions that are not...
