Using breast cancer registry data from the United States and regression models controlling for race, marital status, and county-level variation, this research analyzes the connections between these statistics and the geographic variation of each of them. In doing so, it determines that stage of diagnosis has a significant impact on survival likelihood and the likelihood of death due to breast cancer. It also determines that survival reduces mortality likelihood. Additionally, it determines that stage of diagnosis, survival, and mortality all vary geographically, postulating that the reason for this variation is due to lifestyle variation and uneven medical talent distribution.

Video Game Sales: Does Diversity Pay?

By Hai Lin “Helena” Wu

The video game industry has grown into a mature market in the past decade, surpassing the size of the U.S. film industry in 2009. As a result of the rise in popularity of video gaming amongst many demographic groups of the American population, the underrepresentation of female and ethnic minorities in video games has become an increasingly relevant topic of discussion. This paper empirically examines the effects of including female and ethnic minority lead characters on the equilibrium sales volume of video games. Through the use of a reduced-‐form regression, the equilibrium quantity is regressed on a list of exogenous variables pertinent to the interest of this study. The findings suggest that the inclusion of female and minority lead characters affects sales of different genres of games in distinct manners, suggesting that the video game market has a heterogeneous consumer base with a diverse range of preferences. In addition to empirical work, one of the main contributions of this paper is creating a new and unique dataset (N=712) on game attributes, especially with regard to character gender and ethnicity. This paper’s findings have implications on the game design decisions for video game producers.

Conditional Beta Model for Asset Pricing By Sector in the U.S. Equity Markets

By Yuci Zhang

In nance, the beta of an investment is a measure of the risk arising from exposure to general market movements as opposed to idiosyncratic factors. Therefore, reliable estimates of stock portfolio betas are essential for many areas in modern nance, including asset pricing, performance evaluation, and risk management. In this paper, we investigate Static and Dynamic Conditional Correlation (DCC) models for estimating betas by testing them in two asset pricing context, the Capital Asset Pricing Model (CAPM) and Fama-French Three Factor Model. Model precision is evaluated by utilizing the betas to predict out-of-sample portfolio returns within the aforementioned asset-pricing framework. Our findings indicate that DCC-GARCH does consistently have an advantage over the Static model, although with a few exceptions in certain scenarios.

Market Dynamics and the Forward Premium Anomaly: A Model of Interacting Agents

By Phillip Hogan and Evan Myer

This paper presents a stochastic model of exchange rates, which is used to explain the forward premium anomaly. In the model, agents switch between four trading strategies, and these changes drive the evolution of the exchange rate. This framework is meant to more realistically represent the important market dynamics of exchange rates, as we suspect these to be the cause of the forward premium anomaly. Our simulations of the model indicate two conclusions: (i) many of the statistical regularities observed in currency markets, including the forward premium anomaly, can be thought of as macro-level scaling laws emerging from micro-level interactions of heterogeneous agents, and (ii) the dynamics of estimates of the beta coefficient in tests of UIP are driven by perceived relationships between changes in interest rates and agents’ aggregate views on the value of the exchange rate, which we call the fundamental value. Section I presents an introduction to the topic and section II reviews the relevant literature. Section III provides the theoretical basis of the forward premium anomaly and our model, then the mathematical definition of the model. Section IV presents the results of a typical simulation which section V compares to relevant stylized facts of the currency markets. Sections VI and VII present our results and a conclusion of what we have drawn from the model.

Exceeding the Threshold: Analysis of Public Information Transfer using Instrumental Variables

By Gabrielle Inder

This paper examines how information transfer about contamination levels found at brownfield sites capitalizes into nearby property values. More specifically, a hedonic model is used to test the impact on housing transaction prices when a binary measure (i.e. exceeding a threshold or not) or a continuous measure (i.e. chemical levels) is used. In the analysis, I exploit the variation in the contaminant thresholds, caused by regulatory conditions defined by the state of Massachusetts, holding the contaminant level constant. As thresholds are tied to neighborhood attributes in areas surrounding brownfields, threshold exceedance is potentially correlated to unobserved factors that impact housing values. An instrumental variables approach is used to create variation in threshold
exceedance through the use of an instrument that measures the presence to underground aquifers. After instrumenting for threshold exceedance, my estimates indicate that a 10.8% decrease in housing values occurs when a contaminant threshold is exceeded, while the continuous measures of toxicity indicate a negative but insignificant effect. These findings suggest that policy makers should consider information conveyance when creating policies to inform homeowners of pollution presence, as improved information provision may increase public awareness about local environmental concerns.

Are the Chinese Altruistic? Explaining Motives behind Chinese Intergenerational Transfers using the Strategic Bequest Motive

By Lucy Yin

Two main competing theories regarding intergenerational transfers from adult children to elderly parents exist: the altruism model and the exchange model. The strategic bequest motive supports the exchange model in claiming parents with bequeathable wealth will incentivize children to devote more resources to parents in order to receive a larger bequest. I use data from the Chinese Longitudinal Healthy Longevity Survey to assess whether children increase monetary or time transfers to elderly parents with bequeathable property ownership. My findings suggest an altruistic model at play, which contradicts most findings in East Asian countries but may be a trend found in other developing countries.

The Impact of Online Streaming on Primetime Viewership An Econometric Analysis of Technological Change, Network Practices and Audience Behavior

By Yeshwanth Kandimalla

This study considers the impact of online streaming on the viewership of popular primetime programs aired on four major U.S broadcast networks: ABC, CBS, FOX and NBC. The time period considered will begin with the 2004-2005 TV season through the 2011-2012 season. Technological change, primarily with faster Internet speeds, spurred some growth of online video streaming. Furthermore, over this time period, the four major networks all authorized streaming at different levels. This variation in availability provides the heterogeneity needed to compare the effect of making programs available
online. The existing literature has posited two effects of online streaming: substitution away from traditional TV viewing due to lower costs or complementarity by drawing in additional viewers. Using this framework, this study conducts an empirical analysis of TV viewership and online availability with a panel of more than 3,500 episodes across 8 seasons and 42 programs. The results strongly suggest that online streaming options drive statistically significant substitution away from traditional TV viewing, a trend that can have major consequences for the distribution of TV programs and the broadcast TV business as a whole.

Faith in the Future and Social Conflict: Economic Growth as a Mechanism for Political Stabilization

By Alexander Bloedel

This paper studies the mechanisms that link sociopolitical conflict and (expectations about) economic prosperity. Motivated by a large body of empirical and historical work on the correlation between economic development and democratization, I develop a game-theoretic model of economic growth with political economy constraints. In an economy where low income agents are credit constrained, rapid and robust economic growth leads to increasing inequality early on, but provides the means to mitigate civil conflict when inequality becomes suciently large. The rate and persistence of growth similarly determines the stability of extant political institutions and the ability to transition from dictatorship to democracy.

Implications of Teacher Tenure on Teacher Quality and Student Performance in North Carolina

By Dana Fenster

This paper examines the relationship between teacher tenure and teacher quality in North Carolina, measured via student performance on the state End of Grade (EOG) standardized tests. After presenting a comprehensive synopsis of the current teacher tenure policy, I use data from the North Carolina Education Research Data Center (NCERDC) to compare demonstrated teacher effectiveness across the tenure bubble, defined as one to eight years of teaching experience within the same district. Ultimately, I find that there is significant jump in average teacher quality at the tenure cutoff, suggesting that tenure policy is effective in retaining high quality teachers while removing those who are ineffective.

Determining the Effect of Personal and Familial Wealth on Congressional and State Legislative Election Outcomes

By Anisha Khemlani

This paper seeks to further the debate on money and politics. Specifically, it focuses on the effect of wealth on election outcomes. The goal is to determine the relationship between personal wealth and voter margins of congressional elections and the effect of familial wealth on state legislative elections. A regression analysis of the congressional data suggests that personal wealth does not significantly impact the voter margins of successful candidates. However, a probit analysis of state legislative data suggests that familial wealth can increases candidate’s chances of winning, all else equal. This implies that at the state level, wealth could provide a candidate with advantages, suggesting that money and power may go hand in hand.
