Description
This paper presents a two-period general equilibrium model that incorporates the firm's learning-by-doing under the green subsidies. I use a dynamic version of the Dixit-Stiglitz monopolistic competition model to analyze the impact of the introduction of green subsidies in the presence of pre-existing effluent taxes. I first show that the introduction of green subsidies promotes the demand for green goods, and consumers are better off each period. I then show that even when the green subsidies directly accrue to consumers, firms in the green sector also benefit via boosted demand for green goods. The learning-by-doing effect accelerates the speed of expansion of the green sector in the face of green subsidies. On the other hand, even when the demand for the green goods increases, and greater pollution may result from meeting the increased demand as a whole, environmental quality may still improve if the technology is good enough to sufficiently boost the net positive impact of green consumption on the environment.

Description
The construction industry faces important performance problems such as low productivity, poor quality of work, and work-related accidents and injuries. Creating a high reliability work system that is simultaneously highly productive and exceptionally safe has become a challenge for construction practitioners and scholars. The main goal of this dissertation was to create an understanding of high reliability construction work systems based on lessons from the production practices of high performance work crews. High performance work crews are defined as the work crews that constantly reach and maintain a high level of productivity and exceptional safety record while delivering high quality of work. This study was conceptualized on findings from High Reliability Organizations and with a primary focus on lean construction, human factors, safety, and error management. Toward the research objective, this dissertation answered two major questions. First, it explored the task factors and project attributes that shape and increase workers' task demands and consequently affect workers' safety, production, and quality performance. Second, it explored and investigated the production practices of construction field supervisors (foremen) to understand how successful supervisors regulate task and project demands to create a highly reliable work process. Employing case study methodology, this study explored and analyzed the work practices of six work crews and crew supervisors in different trades including concrete, masonry, and hot asphalt roofing construction. The case studies included one exceptional and one average performing crew from each trade. Four major factors were considered in the selection of exceptional crew supervisors: (1) safety performance, (2) production performance, (3) quality performance, and (4) the level of project difficulty they supervised. The data collection was carried out in three phases including: (1) interview with field supervisors to understand their production practices, (2) survey and interview with workers to understand their perception and to identify the major sources of task demands, and (3) several close field observations. Each trade's specific findings including task demands, project attributes, and production practices used by crew supervisors are presented in a separate chapter. At the end the production practices that converged to create high reliability work systems are summarized and presented in nine major categories.

Description
The dissertation consists of two essays in misallocation and development. In particular, the essays explore how government policies distort resource allocation across production units, and therefore affect aggregate economic and environmental outcomes.
The first chapter studies the aggregate consequences of misallocation in a firm dynamics model with multi-establishment firms. I calibrate my model to the US firm size distribution with respect to both the number of employees and the number of establishments, and use it to study distortions that are correlated with establishment size, or so-called size-dependent distortions to establishments, which are modeled as implicit output taxes. In contrast to previous studies, I find that size-dependent distortions are not more damaging to aggregate productivity and output than size-independent distortions, while the implicit tax revenue approximately summarizes the effects on aggregate output. I also use the model to compare the effects of size-dependent distortions to establishments and to firms, and find that they have different effects on firm size distribution, but have similar effects on aggregate output.
The second chapter studies the effects of product market frictions on firm size distribution and their implications for industrial pollution in China. Using a unique micro-level manufacturing census, I find that larger firms generate and emit less pollutants per unit of production. I also provide evidence suggesting the existence of size-dependent product market frictions that disproportionately affect larger firms. Using a model with firms heterogeneous in productivity and an endogenous choice of pollution treatment technology, I show that these frictions result in lower adoption rate of clean technology, higher pollution and lower aggregate output. I use the model to evaluate policies that eliminate size-dependent frictions, and those that increase environmental regulation. Quantitative results show that eliminating size-dependent frictions increases output by 30%. Meanwhile, the fraction of firms using clean technology increases by 27% and aggregate pollution decreases by 20%. In contrast, a regulatory policy which increases the clean technology adoption rate by the same 27%, has no effect on aggregate output and leads to only 10% reduction in aggregate pollution.

Description
This dissertation consists of three essays on education and macroeconomics. The first chapter analyzes whether public education financing systems can account for large differences among developed countries in earnings inequality and intergenerational earnings persistence. I first document facts about public education in the U.S. and Norway, which provide an interesting case study because they have very different earnings distributions and public education systems. An overlapping generations model is calibrated to match U.S. data, and tax and public education spending functions are estimated for each country. The benchmark exercise finds that taxes and public education spending account for about 15% of differences in earnings inequality and 10% of differences in intergenerational earnings persistence between the U.S. and Norway. Differences in private education spending and early childhood education investments are also shown to be quantitatively important. The second chapter develops a life-cycle model to study increases in college completion and average ability of college students born from 1900 to 1972. The model is disciplined with new historical data on real college costs from printed government surveys. I find that increases in college completion for 1900 to 1950 cohorts are due primarily to changes in college costs, which generate large endogenous increases in college enrollment. Additionally, I find strong evidence that post-1950 cohorts under-predicted large increases in the college earnings premium. Modifying the model to restrict perfect foresight of the education premia generates a slowdown in college completion consistent with empirical evidence for post-1950 cohorts. Lastly, I find that increased sorting of students by ability can be accounted for by increasingly precise ability signals over time. The third chapter assesses how structural transformation is affected by sectoral differences in labor-augmenting technological progress, capital intensity, and capital-labor substitutability. CES production functions are estimated for agriculture, manufacturing, and services on post-war U.S. data. I find that sectoral differences in labor-augmenting technological progress are the dominant force behind changes in sectoral labor and relative prices. Therefore, Cobb-Douglas production functions with labor-augmenting technological change capture the main technological forces behind post-war U.S. structural transformation.

Description
The dissertation explores how participants view the relationships between democratic principles such as freedom, liberty, justice, and equality in work and home environments and their impact on the health and productivity of people living within these environments. This information can be used to determine the gap between legal democratic instruments established the published laws and rights and the participants understanding and awareness of these rights. The first step in effectively capturing information from the participants involved developing a virtual ethnographic research system architecture prototype that allowed participants to voice their opinions related to democracy and how the application of democratic principles in various lived environments such as the workplace and home can affect their health and productivity. The dissertation starts by first delving into what democracy is within the context of general social research and social contracts as related to everyday interactions between individuals within organizational environments. Second, it determines how democracy affects individual human rights and their well-being within lived environments such as their workplace and home. Third, it identifies how technological advances can be used to educate and improve democratic processes within various lived environments such that individuals are given an equal voice in decisions that affect their health and well-being, ensuring that they able to secure justice and fairness within their lives. The virtual ethnographic research system architecture prototype tested the ability of a web application and database technology to provide a more dynamic and longitudinal methodology allowing participants to voice their opinions related to the relationship of democracy in work and home environments to the health and productivity of the people who live within these environments. The technology enables continuous feedback as participants are educated about democracy and their lived environments, unlike other research methods that take a one-time view of situations and apply them to continuously changing environments. The analysis of the participant's answers to the various qualitative and quantitative questions indicated that the majority of participants agree that a positive relationship exists between democracy in work and home environments and the health and productivity of the individuals who live within these environments.
