Standards of mental efficiency.

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Efficiency of Mental Hospitals.

Civilized communities spend much of their resources on the care of the sick. In present-day Britain nearly half the hospital beds are occupied by the mentally ill, so that even a small improvement in the treatment of these patients will be profitable, both in alleviating suffering and in reducing the burden on the community. In the work reported here, we have adopted certain criteria by which t...

Errors in Boiler Efficiency Standards

This paper presents both criticism and suggested changes to boiler efficiency standards associated with fossil-fired steam generators. These standards include the widely used ASME PTC 4.1 and DIN 1942, and their replacements ASME PTC 4:2008 and the European EN 12952-15. For these standards it is useful to review both old and new. The chief criticism lies with inconsistent application of thermod...

Are Energy Efficiency Standards Justified?

This paper develops and parameterizes an overarching analytical framework to estimate the welfare effects of energy efficiency standards applied to automobiles and electricity-using durables. We also compare standards with sectoral and economywide pricing policies. The model captures a wide range of externalities and preexisting energy policies, and it allows for possible “misperceptions”—marke...
