Does trade liberalization foster total factor productivity (TFP) growth in the manufacturing sector? Does sectoral trade orientation determine sectoral TFP levels and growth rates? These questions are addressed using pooled pre-and post-liberalization panel data from Cameroonian firms of eight manufacturing industries. A single production function for the whole manufacturing sector is estimated...

One hundred-thirty soil isolates of A. flavus were collected from commercial pistachio orchards in two main production regions including Rafsanjan (Kerman Province, south-eastern of Iran) and Damghan (Semnan Province, central north of Iran) and assayed for vegetative compatibility groups (VCGs). The sixteen and twenty VCGs were identified for 41 and 37 nit-mutant producing isolates of A. flavus...

Railways were integral to the development of the Indian economy before World War I. In this paper, we present new estimates of total factor productivity (TFP) for railways from 1874 to 1912, which highlight the strong performance of this key industrial sector. We find railway-industry TFP growth to be substantial, averaging 2.5 percent per year and generating a 3 percent social savings for the ...

the distribution of phytophthora parsiana a high-temperature tolerant newly described species was studied in southern iran and examined its host range in woody perennial plant species in greenhouse condition under high inoculum potential. among different plant species examined, almonds were highly susceptible by different isolates. from 24 woody plants inoculated, the disease severity in descen...

BACKGROUND There are no guidelines addressing the public health aspects of methanol poisoning during larger outbreaks. The current study was done to discuss the role of active case finding and a national guideline that organizes all available resources according to a triage strategy in the successful management of a methanol mass poisoning in Rafsanjan, Iran, in May 2013. METHODS A retrospect...

the convergence hypothesis maintains that an economy whose productivity lags behind other economies has a potential to grow faster. in other words, this economy can experience faster economic growth through absorbing, accepting, and using available technology experience. in this study, we have examined the relationship between tfp of industry sectors and regional convergence in iran's prov...

We assess long-run patterns of global agricultural productivity growth between 1970 and 2005 and examine the relationship between investments in technology capital and productivity. To measure agricultural total factor productivity (TFP) we employ a Solow-type growth accounting method to decompose output growth into input and TFP growth. For technology capital we construct two indexes reflectin...

The U.K. skill premium fell from the 1950s to the late 1970s and then rose very sharply. This paper examines the contributions to these relative wage movements of international trade and technical change. We first measure trade as changes in product prices and technical change as TFP growth. Then we relate price and TFP changes to a set of underlying factors. Among a number of results, we find ...

Despite occasional objections total factor productivity (TFP) has been widely recognised as the key determining composite component in the literature on economic growth. Most empirical studies of the contribution of TFP to growth are based simply on the conventional calculations of growth accounting. This paper argues that judging TFP solely in terms of growth accounting carries risks and loses...
