objective: reaching to high economic growth has always been a concern for economic policy makers in developing countries including iran. since labor productivity is one of the most important sources of economic growth, policies are targeted to boost labor productivity in most countries. for realization of this aim, there is a special consideration to health improvement policies because health i...

An important recent development has been the emergence o f a body o f literature by Harva rd economists emphasizing a collective voice/insti tutional response (CV/IR) view of unionism, t Possibly the most controversial aspect o f this literature (hereafter, the Harva rd studies) concerns the effects o f unions on labor productivity. Utilizing a product ion function approach, Brown and Medof f (...

False bad news about population growth, natural resources, and the environment is published widely in the face of contradictory evidence. For example, the world supply of arable land has actually been increasing, the scarcity of natural resources including food and energy has been decreasing, and basic measures of U.S. environmental quality show positive trends. The aggregate data show no long-...

abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...

the purpose of this study is calculate the rate of total factor productivity (tfp) growth  of rice varieties for different provinces of  iran and then breakdown it to the changes in a technology, management efficiency and scale efficiency. for this purpose we use the nonparametric method of comprehensive data analysis and malmquist productivity index. the used data include the rice varieties pr...

abstract in this paper,using a structural decomposition analysis (sda) and the latest available input-output tables we investigate the sources of labor productivity growth in norway, south korea and iran. then, the contribution of each source in the growth of labor productivity is discussed. the results show that among six factors, value added coefficient is the most influencing factoracross al...

a crossbreeding experiment involving four iranian fat-tailed sheep breeds, namely kurdi (k), chaal (c), afshari (a) and sanjabi (s) was carried out to determine the ram breed effects on productivity of kurdi fat-tailed ewes (k) under extensive production system. a total of 475 kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure kurdi, kk, (116 lambs), afshari × ...

The aim of this paper is to analyze total factor productivity (TFP) growth and its components in Asian countries applying Stochastic Frontier Analysis (SFA) to the time series data of 44 Asian countries from 2000 to 2010. Using Battese and Coelli approach, TFP is divided into technical efficiency change and technical change. TFP decomposition using SFA method for the years 1998 to 2007 indicate...
