This paper extends the three major facts of long run structural transformation — (i) sectoral reallocations, (ii) rich movements of productive activities between home and market, and (iii) an increase in the scale of productive units — and develops a model based on scale technologies to understand and explain them within a unified framework. The crucial distinction between industry, services, a...

We present a version of the neoclassical model with an endogenous industry structure. We obtain multiple steady-state equilibria with an arbitrarily small degree of increasing returns to scale. While the most productive …rms operate across all the steady states, in a poverty trap less productive …rms operate as well. This results in lower average …rm productivity and total factor productivity. ...

this paper proposes an alternative approach for efficiency analysis when a set of dmus uses interval scale variables in the productive process. to test the influence of these variables, we present a general approach of deriving dea models to deal with the variables. we investigate a number of performance measures with unrestricted-in-sign interval and/or interval scale variables.

This paper discusses alternative methods for determining returns to scale in DEA. The methods for estimating returns to scale in DEA, as developed by Banker (1984), Banker, Charnes and Cooper (1984) and Banker and Thrall (1992), are proved to be conceptually equivalent to the two-stage methods of F~ire, Grosskopf and Lovell (1985) when their assumptions apply. Here the emphasis is on the CCR mo...

Aceptado: 05-10-2014 Rural women's discrimination and the lack of effective implementation of the legislation on gender equality is a phenomenon found around the world. Women have been traditionally the responsible of family care and feeding, thus they have developed productive tasks that allow combining productive and reproductive activities in the farm. Food processing is one of these activit...

This longitudinal ERP study investigated changes in children's ability to map novel words to novel objects during the dynamic period of vocabulary growth between 20 and 24 months. During this four-month period the children on average tripled their productive vocabulary, an increase which was coupled with changes in the N400 effect to pseudoword-referent associations. Moreover, productive vocabu...

Although appropriate sizing of software projects is a concern in software development, Information Systems managers generally do not consider maintenance project size as a potentid influence on software maintenance productivity. This view ignores potential efficiency gains which may arise from proactive renovation strategies such as batching similar maintenance requests into larger projects. In...

In every decade since the 1970’s, computer scientists have re-examined dataflow-based execution models, hoping the programming productivity benefits these models promise can be realized on practical hardware platforms to implement useful applications. Based on the recent Swift/T implementation of “implicitly parallel functional dataflow” (IPFD) for extremescale systems, we believe that the data...
