One in five children in England are recorded as having some kind of special educational need, meaning that they receive additional help in school; yet there is very little evidence of the effect of such assistance on pupil’s academic progress. This is at least partly because it is usually very difficult to define an appropriate control group for pupils with special educational needs. To overcom...

In 2003 Kenya abolished user fees in all government primary schools. We find that this Free Primary Education (FPE) policy resulted in a decline in public school quality and increased demand for private schooling. However, the former did not reflect a decline in value added by public schools as anticipated if fees contribute to local accountability but rather the selection of weaker pupils into...

We present experimental evidence on the impact of a school choice program in the Indian state of Andhra Pradesh (AP) that provided students with a voucher to finance attending a private school of their choice. The study design featured a unique two-stage lottery-based allocation of vouchers that created both a student-level and a market-level experiment, which allows us to study both the indivi...

This experiment was conducted by using (32000) chicks classified into three houses (18000 chicks in first house, 5000 chicks in second house and 9000 chicks in third house). The first group was inoculated with inactivated oil emulsion vaccine contain NDV (La Sota) and AIV (H9N2) subcutaneous at one day, in the same time vaccinated with mixed vaccine of NDV (La Sota) and IBV H120 by spraying rou...

Education System Reform in Pakistan: Why, When, and How? Pakistan’s education system faces long-standing problems in access, quality, and equal opportunity at every level: primary and secondary schools, higher education and vocational education. In spite of recent encouraging trends, such as the rapid spread of private schooling and an expansion of higher education opportunities, systemic refor...

We recently reported that cytochrome c peroxidase (Ccp1) functions as a H2O2 sensor protein when H2O2 levels rise in respiring yeast. The availability of its reducing substrate, ferrocytochrome c (Cyc), determines whether Ccp1 acts as a H2O2 sensor or peroxidase. For H2O2 to serve as a signal it must modify its receptor so we employed high-performance LC-MS/MS to investigate in detail the oxida...

The Economics of International Differences in Educational Achievement An emerging economic literature over the past decade has made use of international tests of educational achievement to analyze the determinants and impacts of cognitive skills. The cross-country comparative approach provides a number of unique advantages over national studies: It can exploit institutional variation that does ...

The importance of infrastructure in economic development has been increasingly recognized by governments, development institutions, and the research community. Despite a sizable literature on its efficiency and growth effects, the distributive impacts of infrastructure have been largely overlooked, with a few recent exceptions. This is regrettable, particularly given the overwhelming concern ab...

The paper addresses the two-fold rise in teacher-student ratio in the American K-12 school system in the post-World War II period accompanied by the evidence of a decline in the relative quality of teachers. We develop a dynamic general equilibrium framework for analyzing the teacher quantity-quality trade-off and offer an explanation to the observed trends. Our OLG model features two stages of...
