According to the Ahlowalia hypothesis (1995), the growth of total factor productivity (TFP) beside infrastructure investments of government lead to income inequality decrease in rural areas of countries. The main objective of this study is to investigate the effects of public investments such as agricultural R&E, road, education and irrigation on income inequality in rural areas of Iran. In ord...

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...

u sing the database of the animal breeding center ofiran and based on the eligible test-day data from 78969 cows in five provinces: tehran (with 44129 cows), ghazvin (6668), zanjan (1767), isfahan (7572), khorasan-e-razavi (14521) and others (4312) the averages of 426850 ± 966840 and 473860 ± 605330 cells/ml of milk somatic cell count (scc) was calculated for individual cows and herds respectiv...

This thesis consists of two self-contained empirical essays. Essay I investigates the impact of labor subsidies on TFP, and profit per employee is included as a second outcome. Coarsened exact matching (CEM) is performed on the key variables. After matching, a difference-indifference (DID) model is applied. The study shows that firms employing workers with wage subsidies experience negative and...

JEL Bibliographic Code O15, O18, O47, O53 We postulate that inferior factor productivity in China’s noncoastal provinces is a principal reason for their lower economic growth despite high investment rates relative to coastal provinces. Using the residual from a fixed-effect Solow growth model for the years 1978-93, we find that TFP is roughly twice as high in the coastal provinces. We estimate ...
