Description
This dissertation consists of two essays. The first measures the degree to which schooling accounts for differences in industry value added per worker. Using a sample of 107 economies and seven industries, the paper considers the patterns in the education levels of various industries and their relative value added per worker. Agriculture has notably less schooling and is less productive than other sectors, while a group of services including financial services, education and health care has higher rates of schooling and higher value added per worker. The essay finds that in the case of these specific industries education is important in explaining sector differences, and the role of education all other industries are less defined. The second essay provides theory to investigate the relationship between agriculture and schooling. During structural transformation, workers shift from the agriculture sector with relatively low schooling to other sectors which have more schooling. This essay explores to what extent changes in the costs of acquiring schooling drive structural transformation using a multi-sector growth model which includes a schooling choice. The model is disciplined using cross country data on sector of employment and schooling constructed from the IPUM International census collection. Counterfactual exercises are used to determine how much structural transformation is accounted for by changes in the cost of acquiring schooling. These changes account for small shares of structural transformation in all economies with a median near zero.

Description
Microfinance is a term that refers to providing basic financial services to the poor; it has become a powerful tool for poverty alleviation. The idea is a relatively new one - modern microfinance began through experiments in the 1970's - but it has grown quickly and currently serves over 155 million clients worldwide. There are many studies that provide evidence of the positive impact of microfinance and the movement has an array of enthusiastic proponents. It is certainly not the only solution in the battle against poverty, however, and there are also studies that question the true depth of its impact. In looking at microfinance around the globe, one thing becomes clear: although it is an international phenomenon, microfinance has definitely found more success in some regions over others.

Social proof and mismatch of self-preference have been assumed to play an important role in the inference of value. They can be influential factors when it comes to decision-making in a mate-selection environment. In this thesis study, participants took an online survey in the form of a dating website. They answered a series of questions about the traits they would like to see in a potential mate. They were then presented with four potential mates and asked to rank them by their preferences. The results show that participants most preferred the potential mate with a high social proof and a low mismatch of self-preference and least preferred the potential mate with a low social proof and a high mismatch of self-preference. When comparing just social proof and mismatch of self-preference, there was not an interaction effect between the two. I conclude that even though social proof is a powerful influencing factor by itself, it did not have the power to trump the mismatch of self-preference.

Description
This dissertation consists of three essays on the task approach to labor markets. In the first chapter, I document that since 2000 the polarization of wages in the U.S. labor market stopped, as the wages of non-routine manual occupations fell in relative and absolute terms. I analyze the end of wage polarization through the lens of a dynamic general equilibrium model with occupation-biased technical change, human capital accumulation, and occupational mobility. I show that wage polarization ended because workers in non-routine manual occupations had lower initial human capital and lower human capital accumulation over time, and because after 2000 mobility across occupations fell, which magnified the differences in human capital accumulation across occupations. The second chapter estimates the effect of the import competition from China on the intensity of tasks performed by workers within U.S. manufacturing establishments between 2002 and 2017. I measure the changes in the intensity of these tasks by linking information on occupational employment from the Occupational Employment Statistics to the occupational characteristics from the Occupational Information Network (O*NET). I find that this “China shock” led establishments to significantly decrease the intensity of cognitive and interpersonal tasks, and to increase the intensity of manual and routine tasks. These estimations are consistent with US establishments reallocating employment to become more similar to their Chinese competitors and have important implications for the design of public policies. The third chapter explores the importance of changes in the intensity of tasks performed by workers to explain the evolution of wages. Despite changes in the workplace, the literature is based on the questionable assumption that the intensity of tasks remains constant over time. I harmonize and compare over time the intensity of non-routine cognitive, non-routine manual, interpersonal, and routine tasks in the Dictionary of Occupation Title (DOT) and the O*NET. I find the new fact that a sizable part of wage changes is due to increases in the return and the intensity of cognitive tasks. I show that this fact has implications for three well-documented wage trends during the last decades: wage polarization, increasing college premium, decreasing gender-wage gap.

Description
This research paper examines the short-run and long-run effects of population growth on economic growth and the variations in these effects across countries with different levels of development. Using data published by the World Bank and The Maddison Project (2020), a fixed effects model is conducted to examine the relationship between population growth and economic growth in approximately 160 countries over the span of 170 years. The results of this analysis find that lower income countries and countries with lower levels of human capital experience the greatest increases in economic growth due to population growth. Additionally, past population growth explains more of the variation in current population growth which points to strong long-term effects of population growth. These results support the economic theory of convergence whereby developing countries experience faster economic growth than developed countries and the notion that population growth can lead to greater innovative capacities which drive economic growth.
