We analyze the aggregation problem without the assumption that individuals and society have fully determined and observable preferences. More precisely, we endow individuals and society with sets of possible von Neumann-Morgenstern utility functions over lotteries. We generalize the classical neutrality assumption to this setting and characterize the class of neutral social welfare function. Th...

The 1980s was a time of demographic and economic changes: the recession, high interest rates, an aging population, and continuing increases in the number of multiple-earner families. As a result, there has been considerable interest about what has happened to family income (1) during this period. How has income grown and how has it been distributed among families? (2) Did society become more po...

An international working group of clinicians and pathologists met in 2003 under the auspices of the International Society of Nephrology (ISN) and the Renal Pathology Society (RPS) to revise and update the 1982 and 1995 World Health Organization classification of lupus glomerulonephritis. This article compares and contrasts the ISN/RPS classification and the antecedent World Health Organization ...

It is often argued that additional constraints on redistribution such as granting veto power to more players in the society makes property better protected from expropriation. We use a legislative bargainingtype model to demonstrate that this intuition may be flawed. Increasing the number of veto players or raising the supermajority requirement for redistribution may reduce protection on the eq...

WE MUST FOLLOW THE PATH OF THE OCTOBER SOCIALIST REVOLUTION [En, Es] We honour the 100th anniversary of the Great October Socialist Revolution, of the world-historic event of international significance, which demonstrated that capitalism is not invincible. The working class, the leading class of society with its allies have the strength to overthrow capitalism and construct the socialist socie...

Nearly every language contains a term or phrase labeling those youngsters whose actions and styles are sufficiently different as to provoke some suspicion or alarm. Standards for such behavior vary across and within cultures [1] . Though lawbreaking per se is not condoned by middle-class society, the escape of a government espionage agent in the employ of that society is lauded as a major victo...

The set A is low for (Martin-Löf) randomness if each random set is already random relative to A. A is K-trivial if the prefix complexity K of each initial segment of A is minimal, namely ∀n K(A!n)"K(n) + O(1). We show that these classes coincide. This answers a question of Ambos-Spies and Kučera in: P. Cholak, S. Lempp, M. Lerman, R. Shore, (Eds.), Computability Theory and Its Applications: Cur...
