Aflatoxins, carcinogenic toxins produced by Aspergillus fungi, contaminate maize, peanuts, and tree nuts in many regions of the world. Pistachios are the main source of human dietary aflatoxins from tree nuts worldwide. Over 120 countries have regulations for maximum allowable aflatoxin levels in food commodities. We developed social network models to analyze the association between nations' af...

abstract-due to the important role productivity plays in future decision making and programming, the productivity indexes should have accurate quantities. in this study, auto-regressive distributed lag (ardl) and genetic algorithm (ga) methods are applied to time series of 1978-2008 to accurately measure total factor productivity (tfp) in the agricultural sector of iran. the comparison of these...

This paper presents an empirical analysis to improve our understanding of the catch-up and convergence tendencies of total factor productivity (TFP) growth across the Chinese provinces over 2003–2012. After controlling for the province heterogeneity, our regression results show that the Chinese provinces exhibit significant conditional convergence in TFP growth over the sample period. This indi...

this study analyzes the contribution of the sectoral total factor productivity growth (tfpg) and the input's growth to the iran's economy sectors growth during 1345 -1383. the major findings show that the average contribution of tfp growth to non-oil output's growth during first, second and third development plans has been 39.5%, 12.2% and 24.8% respectively, amounting to (as est...

The analysis of the composition of economic growth in the G7 countries has been motivated by the desire to identify regularities that contribute to explaining economic success. Such analysis must be carried out with a long term perspective, and the relevant production function should reflect existing world technology and not just domestic conditions. Moreover, in order to assess the relative pe...

Based on panel data from the National rural fixed point survey 2011 to 2018 and Peking University digital financial inclusion (DFI) index data, this article uses dynamic effect model analyze of access inclusive financing platforms agricultural total factor productivity (TFP) its contributing factors at household level. The results show that DFI have a significant hysteresis positive impact TFP ...

Health is a very essential component of human development because healthy workers are more productive. Using the conventional growth accounting method the study first estimates the aggregate TFP growth for the Indian economy. It examines the impact of health on TFP growth for the Indian economy. It has been observed that TFP growth in India has been fluctuating in nature. Granger Causality test...

Narrowing the rural–urban income gap is an important challenge in achieving sustained and stable economic social development China. The present study investigates role of farmers’ education agricultural productivity growth influencing by applying mediation, interaction, quantile regression models to provincial panel data China from 2003 2017. Results show that, first all, China’s (TFP) continue...

Optimizing the industry development system and implementing a high-quality strategy in China’s coal require us to grasp overall status regional differences of industrial development. Measuring decomposing total factor productivity growth is necessary prerequisite. In this study, we estimated (TFP) 24 major coal-producing provinces China by constructing stochastic frontier analysis (SFA) model b...
