We investigate the use of information in repeated principal-agent game and report three results. First, consistent with Kandori (1992), garbling signals within each period hurts the e¢ ciency of the game. Second, contrary to Abreu, Milgrom, and Pearce (1991), bundling signals across periods and then fully revealing them never increases the e¢ ciency of the game. Third, and most importantly, we ...

Myeloperoxidase (MPO) defi ciency is one of the most common inherited phagocyte defects, but it is rarely associated with clinical symptoms [1]. MPO, which is abundant in azurophilic granules of neutrophils and in the lysosomes of monocytes, plays a key role in amplifying the toxicity of hydrogen peroxide generated by the respiratory burst [1,2]. The diagnosis of MPO defi ciency was rare before...

Analogous to the shift from assembler language programming to the third generation languages in the early years of computer science we are currently wit nessing a paradigm change towards the use of portable programming models in parallel high performance computing Like before the use of a high level program ming environment must be paid for by a reduced system performance But how much does port...

The numbers of older people in the world have been growing rapidly. Anemia is the most common hematologic problem encountered in older adults. However, anemia should not be accepted as an inevitable consequence of aging. Anemia in the elderly signifi es an underlying disease. Iron Defi ciency Anemia (IDA) is being one of the most common causes of anemia in older people. IDA in the elderly is of...

Although the processing power of uniprocessor sys tems is signi cantly increasing every year there is a never ending quest for peak performance The so called grand challenges in computing require more computing power than a single uniprocessor machine can ever o er Recent advances in parallel processing however has brought the solution of grand challenges into reach What is usually neglected wh...

Assume k (k 2) populations are given. The associated independent random variables have continuous distribution functions with an unknown location parameter. The statistical selection goal is to select a non-empty subset which contains the best population, that is the population with largest value of the location parameter with conndence level P (k ?1 < P < 1). Some distributional results for su...

We analyze the interactions between internal and external control mechanisms in a framework in which the board selects the CEO and then decides whether to retain or dismiss him after observing a signal regarding his ability. The novel aspect of our paper is that we consider both the hiring and the ...ring of the CEO by the board. The type of board is de...ned by its ability to select a good CEO...

This paper attempts to develop a theory of su ciency in the setting of non-commutative algebras parallel to the ideas in classical mathematical statistics. Su ciency of a coarse-graining means that all information is extracted about the mutual relation of a given family of states. In the paper su cient coarse-grainings are characterized in several equivalent ways and the non-commutative analogu...

We consider large double auctions with private values. Values need be neither symmetric nor independent. Multiple units may be owned or desired. Participation may be stochastic. We introduce a very mild notion of “a little independence.” We prove that all non-trivial equilibria which satisfy this notion are asymptotically e¢cient. For any ® > 0; ine¢ciency disappears at rate 1=n2¡®.
