We consider complexity issues for a special type of combinatorial auctions, the single-minded auction, where every agent is interested in only one subset of the commodities. First, we present a matching bound on the communication complexity for the single-minded auction under a general communication model. Next, we prove that it is NP-hard to decide whether Walrasian equilibrium exists in a sin...

Abstract Why does human cooperation often unravel in economic experiments despite a promising start? Previous studies have interpreted the decline as reaction of disappointed altruists retaliating response to non-altruists (Conditional Cooperators hypothesis). This interpretation has been considered evidence uniquely form cooperation, motivated by an altruistic concern for equality (‘fairness’)...

The goal of many randomized experiments and quasi-experimental studies in economics is to inform policies that aim to raise incomes and reduce economic inequality. A policy maximizing the sum of individual incomes may not be desirable if it magnifies economic inequality and post-treatment redistribution of income is infeasible. This paper develops a method to estimate the optimal treatment assi...

The Drosophila Single-minded and Tango basic-helix-loop-helix-PAS protein heterodimer controls transcription and embryonic development of the CNS midline cells, while the Trachealess and Tango heterodimer controls tracheal cell and salivary duct transcription and development. Expression of both single-minded and trachealess is highly restricted to their respective cell lineages, however tango i...

In this paper I argue for the claim that self-love is a precondition for self-knowledge. This claim is relevant to the contemporary philosophical debate on self-knowledge, but mainly because it draws attention to the role of claims of self-knowledge in the larger context of our ordinary practice of rationalizing and appropriating our actions. In this practice it is crucial for persons to open-m...
