We discuss how to measure allocative efficiency without presuming technical efficiency. This is relevant when it is easier to introduce reallocations than improvements of technical efficiency. We compare the approach to the traditional one of assuming technical efficiency before measuring allocative efficiency. In particular, we develop necessary and sufficient conditions on the technology to e...

Regulation of cyclic AMP (cAMP) production and muscarinic binding were studied in highly washed left ventricular membranes from spontaneously cardiomyopathic Syrian hamsters (TO strain). Basal production of cAMP was decreased relative to that in random-bred (RB) controls, with proportionally similar decreases in stimulated production elicited by 7 beta-deacetyl-7 beta-(gamma-N-methylpiperazino)...

We use new central stellar velocity dispersions and nuclear X-ray and Hα luminosities for the Palomar survey of nearby galaxies to investigate the distribution of nuclear bolometric luminosities and Eddington ratios for their central black holes (BHs). This information helps to constrain the nature of their accretion flows and the physical drivers that control the spectral diversity of nearby a...

Aim To estimate the prevalence of hazardous drinking and its socio-economic distribution among Russian men. Design Participants were an age-stratified, population-based random sample of men aged 25–54 years living in Izhevsk, a city in the Urals, Russia. Interviewers administered questionnaires to cohabiting proxy respondents about behavioural indicators of hazardous drinking derived from frequ...

This paper presents a model in which goods market distortions lead firms to socially inefficient modes of internal organization. The model seeks to capture the aversion documented by Eccles and White (1988) of middle management aversion to inter-profit center transactions. I consider situations where reputational forces are able to support equilibria in which goods are of high quality. These fo...

Welfare economics typically holds that market outcomes are Pareto efficient only if markets are competitive and average costs are constant or increasing. Otherwise, to attain market efficiency requires some regulatory implementation of a rule to equate price to marginal cost, though the ability of such a pricing rule to accomplish this is tempered by second-best considerations. In contrast to t...

We consider small committees which have to elect one of three alternatives using the simple plurality rule. Committee members have common, state-dependent preferences and receive imprecise private signals about the state of nature prior to the election. We are interested in whether the committee decision is efficient, that is whether the probability with which the committee elects the correct a...

The low-luminosity black hole Sgr A* provides a testbed for models of Radiatively Inefficient Accretion Flows (RIAFs). Recent sub-millimeter linear polarization measurements of Sgr A* have provided evidence that the electrons in the accretion flow are relativistic over a large range of radii. Here, we show that these high temperatures result in elliptical plasma normal modes. Thus, polarized mi...

Previous literature shows that contracting frictions may preclude valuable cooperation between innovators and commercializers in Markets for Technology. This literature, however, does not address the question of how large the implied inefficiency is. Focusing on licensing-based cooperation in the pharmaceutical industry and the enactment of the Medicare Part D program (which implied a large dow...

We present the first results from a time-dependent chemical model to include a gas-phase reaction scheme for producing doubly-deuterated species. Under normal conditions the formation of these species is inefficient. However, when the effects of the freeze out of gas phase species onto grains is included in the chemistry we find that the fractionation of both singly and doubly deuterated specie...
