Description
Schennach (2007) has shown that the Empirical Likelihood (EL) estimator may not be asymptotically normal when a misspecified model is estimated. This problem occurs because the empirical probabilities of individual observations are restricted to be positive. I find that even the EL estimator computed without the restriction can fail to be asymptotically normal for misspecified models if the sample moments weighted by unrestricted empirical probabilities do not have finite population moments. As a remedy for this problem, I propose a group of alternative estimators which I refer to as modified EL (MEL) estimators. For correctly specified models, these estimators have the same higher order asymptotic properties as the EL estimator. The MEL estimators are obtained by the Generalized Method of Moments (GMM) applied to an exactly identified model. The simulation results provide promising evidence for these estimators. In the second chapter, I introduce an alternative group of estimators to the Generalized Empirical Likelihood (GEL) family. The new group is constructed by employing demeaned moment functions in the objective function while using the original moment functions in the constraints. This designation modifies the higher-order properties of estimators. I refer to these new estimators as Demeaned Generalized Empirical Likelihood (DGEL) estimators. Although Newey and Smith (2004) show that the EL estimator in the GEL family has fewer sources of bias and is higher-order efficient after bias-correction, the demeaned exponential tilting (DET) estimator in the DGEL group has those superior properties. In addition, if data are symmetrically distributed, every estimator in the DGEL family shares the same higher-order properties as the best member.

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 Chinese capital market is characterized by high segmentation due to governmental regulations. In this thesis I investigate both the causes and consequences of this market segmentations. Specifically, I address the following questions: (1) to which degree this capital market segmentation is caused by the fragmented regulations in China, (2) what are the key characteristics of this market segmentation, and (3) what are the impacts of this market segmentation on capital costs and resources allocations. Answers to these questions can have important implications for Chinese policy makers to improve capital market regulatory coordination and efficiency. I organize this thesis as follows. First, I define the concepts of capital market segmentation and fragmented regulation based on literature reviews and theoretical analysis. Next, on the basis of existing theories and methods in finance and economics, I select a number of indicators to systematically measure the degree of regulatory segmentation in China’s capital market. I then develop an econometric model of capital market frontier efficiency analysis to calculate and analyze China’s capital market segmentation and regulatory fragmentation. Lastly, I use the production function analysis technique and the even study method to examine the impacts of fragmented regulatory segmentation on the connections and price distortions in the equity, debt, and insurance markets. Findings of this thesis enhance the understanding of how institutional forces such as governmental regulations influence the function and efficiency of the capital markets.

Description
Merton (1987) predicts that idiosyncratic risk can be priced. I develop a simple equilibrium model of capital markets with information costs in which the idiosyncratic risk premium depends on the average level of idiosyncratic volatility. This dependence suggests that the idiosyncratic risk premium varies over time. I find that in U.S. markets, the covariance between stock-level idiosyncratic volatility and the idiosyncratic risk premium explains future stock returns. Stocks in the highest quintile of the covariance between the volatility and risk premium earn an average 3-factor alpha of 70 bps per month higher than those in the lowest quintile.

Description
This paper examines dealers' inventory holding periods and the associated price markups on corporate bonds from 2003 to 2010. Changes in these measures explain a large part of the time series variation in aggregate corporate bond prices. In the cross-section, holding periods and markups overshadow extant liquidity measures and have significant explanatory power for individual bond prices. Both measures shed light on the credit spread puzzle: changes in credit spread are positively correlated with changes in holding periods and markups, and a large portion of credit spread changes is explained by them. The economic effects of holding periods and markups are particularly sharp during crisis periods.

Description
The dissertation is composed by three chapters. In Chapter 2 (coauthored with Matthew Wiswall) I develop new results for the identification and estimation of the technology of children’s skill formation when children’s skills are unobserved. In Chapter 3 I shed light on the importance of dynamic equilibrium interdependencies between children’s social interactions and parental investments decisions in explaining developmental differences between different social environments. In Chapter 4 (coauthored with Giuseppe Sorrenti) I study the effect of family income and maternal hours worked on both cognitive and behavioral child development.

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.

This paper looks at defined contribution 401(k) plans in the United States to analyze whether or not participants have plans with better plan characteristics defined in this study by paying more for administration services, advisory services, and investments. By collecting and analyzing Form 5500 and audit data, I find that there is no relation between how much a plan and its participants are paying for recordkeeping, advisory, and investment fees and the analyzed characteristics of the plan that they receive in regards to active/passive allocation, revenue share, and the performance of the funds.

Description
The purpose of this thesis is to investigate the history of the Bitcoin arbitrage premium to see if the possibility of 'risk-free' gains existed previously and whether or not the opportunity is still present today. It investigates market structure and price discrepancies in $147B of trading volume across 53 different exchanges between July 2010 and February 2017. This paper aggregates exchange trading into five minute buckets of transaction volume in order to see what exchange volume could have been successfully arbitraged within the context of two cases. The first requires trades to close within the same 5-minute interval and the second requires a 10-minute delay before the position is closed. It finds that the monthly average spreads of these cases have fallen below 3% in 2017 from nearly 10% in 2010. Once exchange fees are included, these spreads fall below 2% on average.

Description
This paper studies the dynamic relationship between the pricing of Alternative Asset Management products and macroeconomic variables. It does so using an index of Alternative Asset Management products, employing a VAR framework and examining the implied impulse response functions. I find a bivariate causal relation between the expected rate of return on Alternative Asset Management products and the growth rate of industrial value added. I also find that the CPI, the yield on one-year national debt, the weighted average yield of bond repurchases in interbank bond market, and the one-year loan interest rate can influence the expected return rate of Alternative Asset Management products. An analysis of the variance decomposition suggests that macroeconomic variables have a different impacts on forecast errors variance.
