This study analyzed the productivity of Tuber crops in Nigeria from twenty states between the periods of 1995 -2006 using Data Envelopment Analysis (DEA) to estimate the total factor productivity (TFP) which was further decomposed to reveal the source of productivity growth over the reference period. Negative TFP growth was observed for all the tuber crops considered in the study on the average...

This paper examines the empirical relationship between trade and total factor productivity (TFP) in South Africa. Using data on actual trade protection across different manufacturing sectors, it is shown that trade liberalization had a positive impact on TFP growth during the 1990s. In addition, time-series evidence on macro data supports a positive long-run relationship between TFP and opennes...

This paper analyzes how producer cooperatives may bene t households in rural environments. In particular, it explores if cooperatives help poor households to exit poverty through three mechanisms: increases in prices, total factor productivity, and relaxation of credit constraints. In a multi-period model I characterize the conditions that must hold so that the always poor can exit poverty when...

â â â  â â â â â â  â  abstract â  based on the recent literature of heterogeneous firms, productive firms self select themselves into foreign markets. in this framework, there is a productivity rise prior to exporting. on the other words, different export performance across firms is linked to their heterogeneity. â  the main purpose of the present paper is to examine the so-called hypothesis o...

The rapid expansion of Chinese cities has led to serious urban productivity and eco-environment changes, therefore attracted considerable international academic attention. main objective this study is investigate the theoretical mechanisms practical effects sprawl on green total factor (GTFP), in order provide a reference for optimizing spatial layout promoting high-quality economic development...

This paper is concerned with the estimation of total factor productivity (TFP) growth for the Iranian electric utilities during the period 1980-1993 on the basis of panel data. A translog cost function is used which accommodates firm - specific variability through a one - way error component model. The results show that the Iranian electricity supply industry experienced increasing returns to s...

This paper is a survey of recent contributions to and developments in the relationship between efficiency and productivity via the production function. The objective is to provide a brief discussion on data and on the methods of measuring efficiency and productivity. First, we introduce the reader to the measurement of partial and total factor productivity in the context of static and firm - sp...
