MARKET ASSISTED LAND REFORM IN NE BRAZIL: A STOCHASTIC FRONTIER PRODUCTION EFFICIENCY EVALUATION [PDF]
We evaluate the "Cédula da Terra" Pilot Project, a land reform project whose conception, mechanisms and operational structure is different from traditional agrarian reform based on expropriation.

Comparing the performance of public and private water companies in the Asia and Pacific region : what a stochastic costs frontier shows [PDF]
Estache and Rossi estimate a stochastic costs frontier for a sample of Asian and Pacific water companies, comparing the performance of public and privatized companies based on detailed firm-specific information published by the Asian Development Bank in ...

Advanced Materials, EarlyView.Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

Education externalities in rural Ethiopia: evidence from average and stochastic frontier production functions. [PDF]
Education will have externality effects in agriculture if, in the course of conducting their own private economic activities, educated farmers raise the productivity of uneducated farmers with whom they come into contact.

Advanced Materials, EarlyView.ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

Efficiency of public spending in developing countries : an efficiency frontier approach [PDF]
Government spending in developing countries typically account for between15 and 30 percent of GDP. Hence, small changes in the efficiency of public spending could have a major impact on GDP and on the attainment of the government's objectives.
