How Consumers Make Impulse Purchases and the Influence of Peers and a Market-Based Setting

By Arjan Saraon

Many organizations are designed to protect, educate and helping consumer with their financial decisionmaking. This paper examines the valuation of various nonessential goods in both a marketplace setting and sliderbased setting, and in both a neutral influence and social influence conditionIn a marketplace valuation setting, it is found that prices and pricesearching behavior are the most significant predictors of a decision to checkout a good. In the sliderbased valuation setting, it is found that the condition and a psychological impulsive measure are the most significant indicators of willingnesstopay. Pricesearching behavior indicated that the influence of responsible peers is as effective at reining in impulsive decisions as the more conventional, neutral method. Finally, a phenomena of paying more in the marketplace schema compared to the slider based schema appeared, despite the incentives being exactly the same. This was likely due to anchoring effects of the presented prices and list price.

Program Characteristics and Economic Conditions That Affect WIC Participation

By Amy Tingle

WIC is one of the most expansive food assistance programs in the United States. Despite extensive research demonstrating the health benefits of participation, there is a sizable gap between those that are eligible and those that enroll. This paper studies how economic conditions and program characteristics affect both eligibility and coverage rates using post recession data from 20102013. The results show that the average monthly food benefit is positively correlated with takeup. They also indicate that the unemployment rate is correlated with eligibility but not takeup, meaning that in times of economic downturn, people enroll at the same rate as before.

Proposing an Alternative to the European Central Bank’s Fiscal Convergence Criteria

By Junaid Arefeen

The recent onset of the sovereign debt crisis in the Eurozone has brought the viabil-ity of the Eurozone as a currency area into question. The unsustainable debt and deficit balances accumulated by several Eurozone nations since the adoption of the common currency in 1999, and the consequent incidence of high levels of sovereign default risk in the euro-area, indicate that the fiscal convergence criteria employed by the European Central Bank to monitor the fiscal discipline and sustainability of its members have been largely ineectual. This paper draws upon the theory of optimum currency areas, and proposes a set of business cycle convergence criteria that can be employed as an alternate means to minimize the risk of fiscal imbalances and sovereign default. Economic theory suggests that a currency union with convergent business cycles will be insulated from asymmetric shocks, removing the need for countries to rely wholly on their fiscal policies when dealing with negative shocks (as would be the case in a currency union with non-synchronous countries suering from negative asymmetric shocks). Therefore, as the risk of fiscal imbalances is minimized, a currency union with synchronous business cycles is expected to have low incidences of sovereign default risk. This paper tests this economic intuition empirically, and employs a multivariable panel regression model to determine the relationship between business cycle convergence and sovereign default risk (proxied using sovereign yield spreads). The regressions reveal that the degree of business cycle convergence is one of the main determinants of yield dierentials, and the relationship between the two is negative (as expected). The consistency of the results to numerous robustness checks provide a strong case for substituting the current fiscal convergence criteria with measures that assess the degree of business cycle convergence.

Variations in Turkey’s Female Labor Market: The Puzzling Role of Education

By Rachel Anderson

Although Turkey ranks among the world’s 20 largest economies, female labor force participation in Turkey is surprisingly low.  Relative to other developed countries, however, the proportion of Turkish women in senior management is high.  One explanation for these contrasting pictures of Turkey’s female labor force is education.  To better understand how women’s education and household characteristics explain variations in Turkey’s female labor market, I use annual Turkish Household Labour Force Survey data from 20042012 to estimate five probabilities: the likelihood that a woman (1) participates in the labor force, or is employed in an (2) agricultural, (3) blue collar, (4) lower white collar, or (5) upper white collar job.  I find that labor force participation is relatively high among female primary school graduates, who are most likely to work in agricultural and blue collar jobs.  Highly educated married women are the most likely group to participate in upper white collar jobs, and families favor sending single daughters over wives to work during periods of reduced household income.

The Professor and the Coal Miner: The effect of socioeconomic and geographical factors on breast cancer diagnosis and survival outcome

By Shelley Chen

Previous studies reported that patients who live farther from cancer centers do not necessarily experience delayed cancer detection and shortened survival. However, the results are biased because of the incomplete observation of patient survival, which cannot be properly accounted for with the multivariable regression model. In this thesis, I isolated the effect of the breast cancer patient’s distance to a comprehensive cancer center on the stage of diagnosis and survival using the Cox Proportional Hazards model. I linked data from the Kentucky Surveillance, Epidemiology, and End Results 18, the Kentucky Life Tables, and the Kentucky Area Health Resource Files and identified 37654 patients diagnosed with breast cancer. I estimated the effect of distance on marginal probability of cancer mortality, controlling for non-cancer related death, socioeconomic status, and demographic factors in patients. After controlling for covariates, travel distance between the patient and the nearest comprehensive cancer center was statistically significantly on the breast cancer mortality probability, but not on the stage of diagnosis. In the Kentucky population, patients who were located farther from comprehensive cancer centers experience an increased marginal probability of mortality (proportional hazard = 1.004; 95% CI: [1.000502 1.007311]). The linkage of SEER 18 and AHRF data provided more comprehensive information on the socioeconomic risk factors of cancer mortality than past study datasets. For the stage of diagnosis, a low physician to population ratio and high county-level Medicaid coverage were associated with more advanced stages of diagnosis. In turn, a more advanced stage of diagnosis, lower physician to population ratio, and identification as African American increased the marginal probabilities of mortality.

Deterring Ineffcient Gambling in Risk-Taking Agents

By Ryan Westphal

This paper proposes a model describing the incentive issues faced by principals and agents when the agent has limited liability and is capable of undertaking unidentifiable, inefficient risky behavior. We propose a contract structure by which the principal deters risk by deferring payment to the agent until she reaches an absorbing steady-state in which promised equity alone deters inefficient behavior. The paper discusses the effect of exogenous parameters on the tradeoffs facing the principal as well as the implications they have on the efficient choice of contract. We also outline extensions to the model in which the principal has access to a costly monitoring technology to identify inefficient risk taking. The theoretical results have implications for real-world employment contracts and practices in financial firms such as investment banks and private equity funds.

Medicare’s Prospective Payment System: Do Differences in the Reimbursement Rate Affect Quantity of Care Delivered and Hospital Billing Practices?

By Russell Hollis

When the government changes Medicare policy, payment structures often accommodate the change through lowering reimbursement rates. Changes in reimbursements raise the question of what effect changes have on patient care. Using data sets from the Center for Medicare and Medicaid Services, I examine the diagnosis of major replacement or reattachment of the lower extremity and how the length of stay for patients responds to changing reimbursement rates. I extend my investigation of price incentives to monitor fraudulent coding by hospitals. In a sample of over 470,000 patients in 2,696 hospitals for fiscal year 2012, I find that a 1% increase in reimbursement leads to a .007% increase in length of stay for DRG 470 (without complications) patients and a .057% percent increase for DRG 469 (with complications) patients. I then find that a 10% decrease in reimbursement for DRG 470 or one percent increase for DRG 469 leads to a .0011 increase in fraction of DRG 469 patients in a particular hospital. Lastly, I comment on these results, which point to the evidence of price incentives in quantity of care an the possibility of “upcoding”1.

Google Search Volume Index: Predicting Returns, Volatility and Trading Volume of Tech Stocks

By Rui Xu

This paper investigates the efficacy of using Google Search Volume Index (SVI), a publicly available tool Google provides via Google Trends, to predict stock movements within the tech sector. Relative changes in weekly search volume index are recorded from April 2004 to March 2015 and correlated with weekly returns, realized volatility and trading volume of 10 actively traded tech stocks. Correlations are drawn for three different time periods, each representing a different stage of the financial business cycle, to find out how Search Volume Index correlates with stock market movements in economic recessions and booms. Google SVI is found to be significantly and positively correlated with trading volume and weekly closing price across 2004 to 2015, and positively correlated with realized volatility from 2009-2015. There exists a positive correlation between weekly stock returns and SVI for half of the stocks sampled across all 3 periods. The regression model was a better fit before and during the recession, suggesting the possibility of stronger “herding” behavior during those periods than in recent years.

Understanding Financial Incentive Health Initiatives: The Impact of the Janani Suraksha Yojana Conditional Cash Transfer Program on Institutional Delivery Rates and Out-of- Pocket Health Expenditure

By Ritika Jain

Demand-side financing is a policy tool used by nations to incentivize utilization of public institutions, and India’s Janani Suraksha Yojana (JSY) is one of the largest such financial incentive programs in the world. The program pays eligible pregnant women to deliver their babies in health institutions partnered with the program. This paper studies the impact of the JSY on changes in mothers’ health-seeking behavior to deliver in-facility and on the out-of-pocket expenditure (OOPE) for delivery that they incur. Using data from the most recent wave of India’s District-Level Household Survey conducted in 2007-08, this paper finds that the overall introduction of the program in districts in India does not lead to significant changes in institutional delivery or out-ofpocket expenditure outcomes. Further analysis of subpopulations shows that marginalized populations are responsive to JSY introduction in their district with increased probability of delivering in-facility of 1.10 – 3.40 percentage points. Lastly, results show that receiving JSY payments leads to a 1.34 percentage point increase in the probability of incurring OOPE, but a 4.81 percent decrease in the amount of OOPE incurred. The JSY is helping to reduce overall out-of-pocket spending on deliveries. However, the majority of program benefits are not reaching poor pregnant women as the JSY aims, communicating the need for improvement in population targeting.

The Implications of Population Aging for Economic Growth a Regional Comparative Study

By Paige Muggeridge

I use a reduced form regression model to determine the extent to which population aging accounts for economic growth in each of the nine regions of the world. Predominantly, I build upon the research of Bloom et al. (2010), which is central to formulating my regression equation. I separate the difference between each region’s average growth rate from the world average growth rate into demographic and non-demographic effects using the estimated coefficients. The results suggest that more economically developed regions have potentially benefited from population aging, while less economically developed regions have not.
