In this paper we provide a theory of money markets and private money. We show that preserving symmetric ignorance in liquidity provision is welfare maximizing and strictly dominates symmetric or even perfect information. A key property for the functioning of money markets is when agents have no need to ask questions and no incentive to produce private information about the value of the security...

A CCOKDINC; to Burger (1949: 222) the “problem of refractoriness is perhaps the greatest relatively unsolved problem in reproduction.” Actually, except in ultimate detail, the problem may have been solved (Marshall, 1949a; 1950a). The “refractory period” of Bissonnette (1931; 1937) and certain other authors is here defined as that period of the avian testis cycle when the tubules are in a state...

BACKGROUND Insulin-dependent diabetes mellitus is dominated by a Th1 response whereas atopic diseases such as asthma, eczema and allergic rhinitis are characterized by a Th2 response. Because it is known that Th1 and Th2 cells reciprocally counteract each other, it can be speculated that the prevalence of Th2-mediated diseases is lower in patients with a Th1-mediated disease. OBJECTIVES To co...

Constrained optimization has been extensively used to solve many large scale deterministic problems arising in economics, including, for example, square systems of equations and nonlinear programs. A separate set of models have been generated more recently, using complementarity to model various phenomena, particularly in general equilibria. The unifying framework of mathematical programs with ...

Moving objects databases are particular cases of spatiotemporal databases that represent and manage changes related to the movement of objects. Unlike spatio-temporal applications associated with geographic phenomena where the identity of geographic features may change over time, in moving objects databases the objects maintain their identities but change their locations or shapes through time....

Many mathematical and practical problems can be expressed as constraint satisfaction problems (CSPs). One way to solve a CSP instance is to encode it into SAT and use a SAT-solver. However, important information about the problem can get lost during the translation stage. For example, although the general constraint satisfaction problem is known to be NP-complete, there are some classes of CSP ...

The neurosecretory system which is considered to have an effect, directly or indirectly, on avian gonadal growth has been extensively investigated in various species (see Ishii and Kobayashi, 1962; Farner et al., 1964). More recently, the neurosecretory materials in the anterior median eminence and in the pars nervosa of the Japanese quail under various photoperiodic conditions have been studie...

OBJECTIVE To compare trends and rates of cesarean section delivery by indication in one academic center. MATERIALS AND METHODS A retrospective analysis of the indications of all cesarean sections performed in Edith Wolfson Medical Center, Holon, Israel, a tertiary healthcare university facility, during 1997-2012 was done. Each delivery was assigned to the primary indication noted for that pre...

An increasing number of grid applications manage data at very large scale, of both size and distribution. In this paper we discuss data access and data processing services for such applications, in the context of a grid. The complexity of data management on a grid arises from the scale, dynamism, autonomy, and distribution of data sources. The main argument of this paper is that these complexit...
