Description
This dissertation comprises three chapters.
In chapter one, using a rich dataset for the United States, I estimate a series of models to document the birth order effects on cognitive outcomes, non-cognitive outcomes, and parental investments. I estimate a model that allows for heterogeneous birth order effects by unobservables to examine how birth order effects varies across households. I find that first-born children score 0.2 of a standard deviation higher on cognitive and non-cognitive outcomes than their later-born siblings. They also receive 10\% more in parental time, which accounts for more than half of the differences in outcomes. I document that birth order effects vary between 0.1 and 0.4 of a standard deviation across households with the effects being smaller in households with certain characteristics such as a high income.
In chapter two, I build a model of intra-household resource allocation that endogenously generates the decreasing birth order effects in household income with the aim of using the model for counterfactual policy experiments. The model has a life-cycle framework in which a household with two children confronts a sequence of time constraints and a lifetime monetary constraint, and divides the available time and monetary resources between consumption and investment. The counterfactual experiment shows that an annual income transfer of 10,000 USD to low-income households decreases the birth order effects on cognitive and non-cognitive skills by one-sixth, which is five times bigger than the effect in high-income household.
In chapter three, with Francesco Agostinelli and Matthew Wiswall, we examine the relative importance of investments at home and at school during an important transition for many children, entering formal schooling at kindergarten. Moreover, our framework allows for complementarities between children's skills and investments from schools. We find that investments from schools are an important determinant of children's skills at the end of kindergarten, whereas parental investments, although strongly correlated with end-of-kindergarten outcomes, have smaller effects. In addition, we document a negative complementarity between children's skills at kindergarten entry and investments from schools, implying that low-skill children benefit the most from an increase in the quality of schools.

Description
This dissertation consists of two parts. The first part is about understanding the mechanism behind female labor supply movement over economic development. Female labor force participation follows a U-shape pattern over per capita GDP cross nationally as well as within some countries. This paper questions if this pattern can be explained through sectoral, uneven technological movements both at market and at home. For that I develop a general equilibrium model with married couples and home production. I defined multiple sectors both at home and in the market. And by feeding the model with uneven technological growth, I observe how participation rate moves over development. My results indicate that a decrease in labor supply is mainly due to structural transformation. Meaning, a higher technology in a large sector causes prices to go up in that sector relative to other. Hence, labor allocated to this sector will decrease. Assuming this sector has a big market share, it will decrease the labor supply. Also, I found that the increase in female labor supply is mostly because of movement from home to market as a result of a higher technological growth in the market. The second part is about developing a methodology to verify and compute the existence of recursive equilibrium in dynamic economies with capital accumulation and elastic labor supply. The method I develop stems from the multi-step monotone mapping methodology which is based on monotone operators and solving a fixed point problem at each step. The methodology is not only useful for verifying and computing the recursive competitive equilibrium, but also useful for obtaining intra- and inter-temporal comparative dynamics. I provide robust intra-temporal comparative statics about how consumption and leisure decisions change in response to changes in capital stock and inverse marginal utility of consumption. I also provide inter-temporal equilibrium comparative dynamics about how recursive equilibrium consumption and investment respond to changes in discount factor and production externality. Different from intra-temporal comparative statics, these are not robust as they only apply to a subclass of equilibrium where investment level is monotone.

Description
This dissertation consists of three essays on modern economic growth and structural transformation, in particular touching on the reallocation of labor across industries, occupations, and employment statuses.
The first chapter investigates the quantitative importance of non-employment in the labor market outcomes for the United States. During the last 50 years, production has shifted from goods to services. In terms of occupations, the routine employment share decreased, giving way to increases in manual and abstract ones. These two patterns are related, and lower non-employment had an important role. A labor allocation model where goods, market services, and home services use different tasks as inputs is used for quantitative exercises. These show that non-employment could significantly slow down polarization and structural transformation, and induce significant displacement within the labor force.
The second chapter, coauthored with Bart Hobijn and Todd Schoellman, looks at the demographic structure of structural transformation. More than half of labor reallocation during structural transformation is due to new cohorts disproportionately entering growing industries. This suggests substantial costs to labor reallocation. A model of overlapping generations with life-cycle career choice under switching costs and structural transformation is studied. Switching costs accelerate structural transformation, since forward-looking workers enter growing industries in anticipation of future wage growth. Most of the impact of switching costs shows on relative wages.
The third chapter establishes that job polarization is a global phenomenon. The analysis of polarization is extended from a group of developed countries to a sample of 119 economies. At all levels of development, employment shares in routine occupations have decreased since the 1980s. This suggests that routine occupations are becoming increasingly obsolete throughout the world, rather than being outsourced to developing countries. A development accounting framework with technical change at the \textit{task} level is proposed. This allows to quantify and extrapolate task-specific productivity levels. Recent technological change is biased against routine occupations and in favor of manual occupations. This implies that in the following decades, world polarization will continue: employment in routine occupations will decrease, and the reallocation will happen mostly from routine to manual occupations, rather than to abstract ones.

Description
A growing number of jobs in the US require a college degree or technical education, and the wage difference between jobs requiring a high school diploma and a college education has increased to over $17,000 per year. Enrollment levels in postsecondary education have been rising for at least the past decade, and this paper attempts to tease out how much of the increasing enrollment is due to changes in the demand by companies for workers. A Bartik Instrument, which is a measure of local area labor demand, for each county in the US was constructed from 2007 to 2014, and using multivariate linear regression the effect of changing labor demand on local postsecondary education enrollment rates was examined. A small positive effect was found, but the effect size in relation to the total change in enrollment levels was diminutive. From the start to the end of the recession (2007 to 2010), Bartik Instrument calculated unemployment increased from 5.3% nationally to 8.2%. This level of labor demand contraction would lead to a 0.42% increase in enrollment between 2008 and 2011. The true enrollment increase over this period was 7.6%, so the model calculated 5.5% of the enrollment increase was based on the changes in labor demand.

Description
A recession at the time of high school graduation could place multiple and competing pressures on a student deciding between entering the labor force and going to college. A recession may lower opportunity costs, increasing college enrollment and depressing the college wage premium; a downturn may also restrict enrollment to only those with sufficient family resources to pay for it. In the event that either of these illustrations holds true, recessions would seem to result in an adverse, exogenous welfare impact. This paper examines the extent to which recessions at the time of high school graduation affect students' likelihood of enrolling in college and then looks at the long-term earnings effects these early-life recessions carry. I first describe the choice between entering a volatile labor market and enrolling in higher education that faces 18-year-old high school graduates during a recession. For my analysis, I use data from the Panel Study of Income Dynamics to study the effects recessions have on high school graduates' decision-making. I then develop a model using these same data to compare the college wage premiums for individuals treated and untreated by a recession at the time of high school graduation. I find that recessions result in an economically significant uptick in college enrollment. However, the college wage premium for those who enroll in a recession is not statistically different from that witnessed by enrollees in better economic climates. Nonetheless, those young people who enter college during a recession may witness an economically appreciable earnings premium over and above the typical college premium. I conclude by exploring the significance of these findings and reflect on their seemingly contradictory implications.

Description
This dissertation consists of three chapters. The first two explore the impact of government policies on human capital accumulation.
Chapter one makes two novel contributions related to the two workhorse models in the human capital literature: Learning by Doing (LBD) and Ben-Porath (BP).
First, I show that BP is much more consistent with empirical life-cycle patterns related to individual earnings growth rates relative to LBD.
Second, I show that the same model features that generate different life-cycle predictions between models also generate different policy implications. In particular, increasing the top marginal labor tax rate, relative to the current US level, generates much larger reductions in lifetime human capital accumulation in the BP model versus the LBD model.
Chapter two examines reforms to the Social Security taxable earnings cap in the context of a human capital model. Old age Social Security benefits in the US are funded by a 10.6% payroll tax up to a cap of $118,500. There has been little work examining the likely outcomes of such a policy change. I use a life-cycle BP human capital model with heterogeneous individuals to investigate the aggregate and distributional steady state impacts of several policy changes the earnings cap. I find that when I eliminate the cap: (1) aggregate output and consumption fall substantially; (2) the role of endogenous human capital is first order; (3) total federal tax revenues are lower or roughly unchanged; (4) about 1/3 of workers are made worse off.
The final chapter studies the existence and optimality of equilibria in the presence of asymmetric information. I develop an equilibrium concept which corresponds to the presence of mutual insurance organizations for a class of adverse selection economies which includes the Spence (1973) signaling and Rothschild-Stiglitz (1976) insurance environments. The defining features of a mutual insurance organization are that policy holders are also the owners of the organization, and that the organization can write policies for which the terms depend on the experience of the mutual members. In general the equilibrium exists and is weakly Pareto optimal. Further, all equilibria have the same individual type utility vector.

Description
Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

Description
Firms reduce investment when facing downward wage rigidity (DWR), the inability or unwillingness to adjust wages downward. I construct DWR measures and exploit staggered state-level changes in minimum wage laws as an exogenous variation in DWR to document this fact. Following a minimum wage increase, firms reduce their investment rate by 1.17 percentage points. Surprisingly, this labor market friction enhances firm value and production efficiency when firms are subject to other frictions causing overinvestment, consistent with the theory of second best. Finally, I identify increased operating leverage and aggravation of debt overhang as mechanisms by which DWR impedes investment.

Description
Are heterogeneous labor market outcomes a product of markets efficiently allocating resources or the result of structural market failures which should be corrected through well-crafted policy? In order to address this fundamental question in modern economics, we must first understand the forces which shape individuals' earnings, employment, and occupational choices. This collection of essays provides new evidence to support several novel channels which influence labor markets. First, I evaluate the connection between technological change and labor market outcomes by bringing new data and methods to study the mechanization of American agriculture in the early 20th century. Using an instrumental variables estimation strategy, I find that exogenous increases in exposure to technological change generated occupational displacement for incumbent laborers, increased income inequality, and had important impacts on intergenerational mobility for the children of affected workers. Additionally, I investigate the connection between low-opportunity neighborhoods and public housing residents' labor market outcomes. Leveraging quasi-random variation in neighborhood quality due to a public housing demolition, I find that residents' wages increased after moving to higher-opportunity neighborhoods and that more intense supportive services improved post-move employment. Taken together, these essays provide new evidence that both large-scale factors like new technologies and local factors like neighborhood quality contribute to heterogeneity in labor market outcomes both historically and up to the present day.

Description
The narratives on technological change and the emergence of the "fourth industrial revolution" (4IR) play a significant role in defining what has happened and is happening in the labor market. Those narratives, mainly based in developed countries, have served as a turning point for policy development, especially regarding the design and implementation of educational and labor strategies as policy instruments to cope with the challenges of inequality and its labor-related causes. However, the specificities of past labor and educational policies play a crucial role in understanding the possible effects of large-scale transformations related to technological change. In this research, I develop a theoretical model connecting the experience of the third industrial revolution, the current assumptions for the future of work agenda, the forecast regarding the possible impacts of the fourth industrial revolutions, and the areas for policy intervention. I use the model to craft a case study, where I present evidence regarding the evolution of the Chilean labor market between 1990 and 2020, following the evolution of job polarization, occupational composition, workforce educational attainment, economic complexity, and the technological ecosystem. I compared those elements with the stylized facts and assumptions of the narratives of technological change. I argue that the differences in the process of workforce adaptation (timing and material conditions) can shed light on the assumptions of the “future of work” agendas, especially by tackling how different conditions could reach different results and craft substantively different base scenarios for policy design and implementation of human capital-based interventions as the ones suggested by international organizations and forums. In the concluding chapter, I summarize the findings and comment on how to address the design of just labor transitions.
