Evidence from recent randomized …eld experiments on community-based monitoring reveals substantial heterogenous treatment e¤ects. Using data from a randomized experiment in primary health in Uganda, we test whether social heterogeneity can explain why some communities managed to push for better health service delivery while others did not. The results suggest that income inequality, and particu...

This paper employs the Ordinary Least Squares, Instrumental Variables and Treatment Effect models to a new dataset from the Vietnam Household Living Standards Survey (VHLSS) to estimate return to four-year university education in 2008. Our estimates reveal that income premium of four-year university education is about 97 percent above that of high school education, and robust to the various est...

Using a strict, age-specific lockdown order for adults aged 65 and older in Turkey, we examine the mental health consequences of an extended period tight mobility restrictions on senior adults. Adopting regression discontinuity design, find that curfew-induced decline substantially worsened outcomes, including somatic nonsomatic symptoms distress (approximately 0.2 standard deviation). Explorin...

We assess whether imperfect knowledge of labor regulation hinders job creation at small and medium-sized firms. partner with a law expert organization that provides information about via newsletters access to specialized website. randomly assign 1,800 firms get this service for 21-week period. Six months later, the average employment level treatment was 12 percent higher than control The interv...

We consider a Rebelo (1991) type model of endogenous growth in which the environmental quality positively affects the rate of human capital accumulation and the environmental quality itself is positively affected by human capital accumulation and is negatively affected by physical capital accumulation. We analyse the effects of taxation on the steady state equilibrium growth rate in this model....

We study how search frictions in the labor market affect firms’ ability to recruit talented workers. In a field experiment Ethiopia, we show that an employer can attract more applicants by offering small monetary incentive for making job application. Estimates from structural model suggest intervention is effective because cost of application large, and positively correlated with jobseeker abil...

We study the effect of political ideology on sustainable development, measured as investment in genuine wealth, in a dynamic panel of 79 countries between 1981 and 2013. We find that a switch from a left-wing or centrist government to a right-wing government has a robust positive and statistically significant effect on investment in genuine wealth. We find no evidence of opportunistic cycles in...

Quintuple perovskites Sm2Ba3Fe5-xCoxO15-δ (x ​= ​0.5, 1.0 and 1.5) have been prepared by glycerin-nitrate technique in air. The phase purity was confirmed XRD. Partial substitution of Co for Fe decreases the oxygen content thus mean oxidation state 3d-metals. It also slightly thermal expansion coefficient oxides. Positive value Seebeck p-type conductivity, though thermopower as increases. tempe...
