Essays on the Political Economy of Education Reforms

“Books will soon be obsolete in the public schools. Scholars will be instructed through the eye. It is possible to teach every branch of human knowledge with the motion picture. Our school system will be completely changed inside of ten years.” Thomas Edison, 1913A century after the great inventor Thomas Edison’s bold prediction about the future of education, we find ourselves in an era where the school system looks strikingly similar to that of a hundred years ago. Teachers still make lectures in front of students, and students still take notes from the blackboard. The motivation for my research springs from the puzzle of why Thomas Edison was sorely mistaken. My work engages with the study of the political economy of education policy formation and the dynamics affecting the passage of education reforms. This dissertation revolves around a few basic questions. What political and economic environment engenders reforms in education? Through which mechanisms do interest groups influence the composition of education policy? What role does social mobility play in the way democratic processes shape education reforms? To answer these questions, I use variations of a unique dataset on education reforms, which I compiled from state-level education legislation in the United States.publishe

From planning to chaos to market : Ethnic inequality in Bulgaria

We document changes in relative earnings of the ethnic Turkish workers in Bulgaria through the country’s transition from planning to markets. Using data from four periods: pre-transition communist era (late 1980s), early transition years (early 1990s), late transition years (early 2000s), and post-transition (late 2000s), we find that the level of raw ethnic inequality (measured as earnings differences between Turkish and Bulgarian workers) increased immediately after the regime change and plateaued throughout the course of transition. Ethnic inequality measures adjusted for observable characteristics follow a similar pattern but post-transitional differences between ethnic groups disappear. Changes over time in the ethnic earnings gaps differ for men and women. The raw and adjusted male ethnic gaps increased steadily during transition years but dropped post-transition, while the raw female ethnic gap fluctuated across the four periods. The adjusted female ethnic gap disappeared completely in the postransitional years. We identify different sources of the changes in the level of ethnic inequality, such as changes in the labor market characteristics and in the wage structure. Evidence suggests that the decline in the relative earnings of Turkish men was due primarily to the widening of the wage structure. Turkish working women improved their relative standing mainly from more favorable changes in labor market characteristics. These changes were only partially due to a selection in labor force participation.publishe

Resilience of Railway Transport to Four Types of Natural Hazards: An Analysis of Daily Train Volumes

A crucial step in measuring the resilience of railway infrastructure is to quantify the extent of its vulnerability to natural hazards. In this paper, we analyze the vulnerability of the German railway network to four types of natural hazards that regularly cause disruptions in German rail operations: floods, mass movements, slope fires, and tree falls. Using daily train traffic data matched with various data on disruptive events, we quantify the extent to which these four types of natural hazard reduce daily train traffic volumes. With a negative binomial count data regression, we find evidence that the track segments of the German railway network are most vulnerable to floods, followed by mass movements and tree-fall events. On average, floods reduce traffic on track segments by 19% of the average daily train traffic, mass movements by 16%, and tree fall by 4%. Moreover, when more than one type of natural hazard affects the track segment on the same day, train traffic on that segment falls by 34% of the average train traffic. Slope fires have an ambiguous and nonrobust effect on train traffic due to the reverse causality due to its triggering factors. This is the first study that attempts to rank different natural hazards according to their impact on railway traffic. The results have implications for the selection of resilience strategy and can help prioritize policy measures

Democracy and poverty reduction

The past decade was witness to the rapid economic growth of countries whose political systems deviate from conventional democratic philosophy. Countries such as Taiwan, Singapore, and South Korea, among others, have become big economies rivaling major players like the United States and the United Kingdom. On the other hand, democratic, low-income countries have experienced relatively sluggish growth. In this paper, we explore the influence of democracy and political freedom on economic growth, utilizing poverty reduction as its indicator. We will focus on identifying the requisites of a functioning democracy within the context of developing nations that will enable it to effectively reduce poverty. Utilizing the 2-stage least squares method of estimation, our findings suggest that democracy, in general, has a negative influence on poverty reduction for developing countries. However, when complemented with trade openness, primary education, regulatory quality, effective governance, and voice and accountability, the outcome becomes positive.democracy, poverty, 2-stage least squares
