An efficient and well-operated network is designed so that its parts function well together. This coordinated efficiency arises from having each element of a network perform those tasks for which it is best designed. Similar to the division of labor in a human society, the division of labor amongst elements in a communications network allows them to maximize the network’s output (e.g., bandwidt...

2 A sizable share of unemployment can be attributed to frictions in the labor market. The simultaneous existence of vacancies and job seekers proves that job search requires effort and time. To improve the efficiency of this process, many countries offer active labor market policies. Evaluating how these programs affect job prospects of job seekers is crucial for effective policy making and for...

This paper aims at estimating the efficiency of hydroelectric power plants (renewable energy resources) and thermal power plant (non-renewable energy resources) in Iranian provinces. Data Envelopment Analysis (DEA) approaches is applied to estimate the efficiency. The network is modeled as a linear system with multiple inputs and one output. Fuel cost, labor force, operation cost are used as in...

In exploring the impact of tax policy on labor-market performance, the paper first investigates how tax reform impacts labor supply and equilibrium unemployment in representative agent models. The impact of tax policy on labor market performance depends importantly on various other labor-market institutions, such as minimum wage laws, wage bargaining, and unemployment benefits. In non-competiti...

The ecological success of social insects is often attributed to an increase in efficiency achieved through division of labor between workers in a colony. Much research has therefore focused on the mechanism by which a division of labor is implemented, i.e., on how tasks are allocated to workers. However, the important assumption that specialists are indeed more efficient at their work than gene...

A representative sample of 49 state and collective farms in Ukraine provides data in physical units on livestock and crop production and input use for 1989-92. The changes in production efficiency for beef, pork, dairy, winter wheat, grain, and potato production, investigated using stochastic frontier methods, show declining technical efficiency in livestock production and especially low margin...

Using China’s provincial economic and pollution data from 1992 to 2008, we employ data envelope analysis (DEA) and econometric analyses to explicitly estimate technical efficiency and examine the role of technical efficiency, pollution control instruments (pollution levy and pollution quantity control), and prices of production inputs on pollution intensity. We find that an increase of labor wa...

This article applies recent advances in productivity and efficiency measurement to the evaluation of skillbiased technical change. Using the general index approach we are able to establish an explicit and unconstrained time path for nonneutral technical change between production and nonproduction labor in U.S. manufacturing industries over the 1959-1996 period. Our findings confirm the prevaili...
