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...

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...

Nationalism creates and recreates a sense of distinctive identity and autonomy based on the Enlightenment idea of human freedom that enables people to survive in a modern world in which unpredictable change has become the norm. While, in the medieval world, the feudal states invoked religion and cultural resources to make people servile, the modern state invokes identity in a language of servin...

In this paper, we develop an account of the failure of private marketgovernance institutions to maintain market order by highlighting how control of their distributional function by powerful elites limits their regulatory capacity. We examine the New York Clearing House Association (NYCHA), a private market-governance institution among commercial banks in Manhattan that operated from 1853 to 19...

Community-based development has been criticized for its inadequate understanding of power relationships at the local level, which thus leaves room for elite capture. This paper compares and contrasts two case studies, both of which take power seriously in their institutional designs. The solar home system in Bangladesh, represents the ‘counter-elite’ approach and explicitly excludes local elite...

BACKGROUND. Sex-specific differences in attitudes and behaviors, arising from a division of human nature into male and female types, have been core findings of evolutionary psychology and are now among its key investigational presumptions. These differences have largely been ignored by mainstream political and social theories. METHOD. I explored one potential path toward incorporation, using ''...

The aim of this paper is to analyze whether the recruitment of elites in the Western world leads to social cohesion, or to the opposite -social stratification. We show that the main change that occurred in the way the Western world trained its elites is that meritocracy became the basis for their recruitment. Although meritocratic selection should result in the best being chosen, we show that m...

Many societies became Muslim gradually, without conquest by Muslim rulers. Explanations of this process typically focus on Muslim traders, proselytizing ‘holy men’, and the conversion of ruling elites, as the limited sources suggest. Yet it cannot be assumed that Islamization always made sense for elites as a power-enhancing stratagem, or that rulers or holy men were willing or able to shape th...
