Prosocial Option Increases Women’S Entry Into Competition, Alessandra Cassar, Mary L. Rigdon

ESI Publications

We provide evidence that women enter competitions at the same rate as men when the incentive for winning includes the option to share part of the rewards with the losers (i.e., when the incentive system is socially oriented). Using an experiment (with N = 238 subjects from three laboratories), we find that about 16% more men than women choose to compete in the standard tournament; this gender gap is eliminated in the socially oriented incentive treatment. While men’s choice to compete remains unchanged, at around 52% in both conditions, women increase their entry rate from 35% in the standard tournament …

Coresets For Regressions With Panel Data, Lingxiao Huang, K. Sudhir, Nisheeth Vishnoi

Cowles Foundation Discussion Papers

This paper introduces the problem of coresets for regression problems to panel data settings. We first define coresets for several variants of regression problems with panel data and then present efficient algorithms to construct coresets of size that depend polynomially on 1/ε (where ε is the error parameter) and the number of regression parameters – independent of the number of individuals in the panel data or the time units each individual is observed for. Our approach is based on the Feldman-Langberg framework in which a key step is to upper bound the “total sensitivity” that is roughly the sum of …

Organizational Structure And Pricing: Evidence From A Large U.S. Airline, Ali Hortaçsu, Olivia R. Natan, Hayden Parsley, Timothy Schwieg, Kevin R. Williams

Cowles Foundation Discussion Papers

Although typically modeled as a centralized firm decision, pricing often involves multiple organizational teams that have decision rights over specific pricing inputs. We study team input decisions using comprehensive data from a large U.S. airline. We document that pricing at a sophisticated firm is subject to miscoordination across teams, uses persistently biased forecasts, and does not account for cross-price elasticities. With structural demand estimates derived from sales and search data, we find that addressing one team’s biases in isolation has little impact on market outcomes. We show that teams do not optimally account for biases introduced by other teams. We …

Teaching Math With Confidence-Recommendations For Improving Numeracy From The Lens Of Confidence Building, Louie Bernard A. Jacob, Miguel Angelo S. Rabago, Hans Erickson A. Tan, Lawrence Dacuycuy, Gerardo L. Largoza, Maria Fe Carmen L. Dabbay

Angelo King Institute for Economic and Business Studies (AKI)

Despite the vast amount of literature surrounding the topic of financial literacy and related problems, there is still no universally accepted solution to this issue because the main factors causing financial literacy problems are still not fully understood both by researchers and current policy-makers. A possible new approach was discovered by Skagerlund et al. (2018), as their research suggested that financial literacy is driven by numeracy (the ability to process and perform basic numerical concepts and calculations) rather than direct knowledge about financial concepts. Given that numeracy is an effort based task, this policy brief provides a list of recommendations …

Behavioral Bias In Occupational Fatality Risk: Theory, Evidence, And Implications, Perry Singleton

Center for Policy Research

Behavioral bias in occupational fatality risk is introduced to the theoretical framework of hedonic wages, yielding an endogenous risk ceiling that increases social welfare. Empirically, bias is most evident among workers with no high school diploma, who do not report relatively greater exposure to death in high fatality rate occupations. These findings suggest that extant population estimates of value of statistical life are biased downwards and should be factored by at least 1.35. Under reasonable assumptions, simulations suggest an optimal risk ceiling between 73.0 to 85.9 percentile of the population distribution of occupational fatality risk.

The Effects Of Recreational Cannabis Access On Labor Markets: Evidence From Colorado, Avinandan Chakraborty, Jacqueline Doremus, Sarah Stith

Economics

Recreational cannabis markets possibly increase labor demand through investments in facilities for growing, processing, and retail sales of cannabis, as well as through other industries such as manufacturing, leisure, and hospitality. However, this increase in labor demand may vary substantially across counties within a state as most states with legal recreational canna-bis allow individual counties to ban commercial cannabis sales. Meanwhile, labor supply may change through positive and negative effects from cannabis use. Using county-level Colorado data from 2011 to 2018 and exploiting variation across counties in the existence and timing of the start of dispensary sales, we test for …

A Data Envelopment Analysis Approach To Portfolio Selection: An Application To The Blue Chip Stocks In The Philippine Stock Exchange (2010-2019), Vishal Bhagia, Colleen Monica K. Chiu, Paulynne J. Castillo, Roberto B. Raymundo, Joel Q. Tanchuco

Angelo King Institute for Economic and Business Studies (AKI)

There has been a growing interest in the application of data envelopment analysis (DEA) as a nonparametric approach in portfolio optimization due to its flexibility in overcoming the limitations of the conventional mean-variance portfolio (MVP) model. Therefore, this study aims to validate the allocative efficiency of the DEA cross-efficiency model using blue chip stocks in the Philippine Stock Exchange from 2010 to 2019. This study finds that the proposed model is able to distinguish a unique set of best-performing stocks across each holding period and outperforms the MVP more consistently. The results of this study suggest that the proposed DEA …

Co-Worker Altruism And Unemployment, Jorge Vásquez, Marek Weretka

Economics: Faculty Publications

It is well-known that social relationships and altruism among workers foster cooperation in the workplace and, therefore, may have beneficial effects for firms. Yet it is unclear how and to what extent co-worker altruism impacts labor market outcomes. In this paper, we find that, although co-worker altruism may be seamless in good times, it may impact the functioning of labor markets during bad times. Specifically, co-worker altruism may potentially lead to wage rigidity and involuntary unemployment in economic downturns. These results seem to be consistent with recent empirical findings.

Stock Return Prediction Using Financial News: A Unified Sequence Model Based On Hierarchical Attention And Long-Short Term Memory Networks, Haoling Chen, Peng Liu

Research Collection Lee Kong Chian School Of Business

Stock return prediction has been a hot topic in both research and industry given its potential for large financial gain. The return signal, apart from its inherent volatility and complexity, is often accompanied by a multitude of noises, such as other stocks’ performance, macroeconomic factors and financial news, etc. To better characterize these factors, we propose a new model that consists of two levels of sequence: an NLP-based module to capture the sequential nature of words and sentences in the financial news, and a time-series-based module to exploit the sequential nature of adjacent observations in the stock price. In this …

Health Insurance And Subjective Well-Being: Evidence From Two Healthcare Reforms In The United States, Seonghoon Kim

Research Collection School Of Economics

We study the role of access to health insurance coverage as a determinant of individuals' subjective well-being (SWB) by analyzing large-scale healthcare reforms in the United States. Using data from the Behavioral Risk Factor Surveillance System and Panel Study of Income Dynamics, we find that the 2006 Massachusetts reform and 2014 Affordable Care Act Medicaid expansion improved the overall life satisfaction of Massachusetts residents and low-income adults in Medicaid expansion states, respectively. The results are robust to various sensitivity and falsification tests. Our findings imply that access to health insurance plays an important role in improving SWB. Without considering psychological …

Monetary Transmission In Money Markets: The Not-So-Elusive Missing Piece Of The Puzzle, Zhengyang Chen, Victor Valcarcel

Faculty Publications

We investigate the effects of U.S. monetary policy shocks from alternative policy indicators for a modern sample encompassing 1988–2020. The choice of the Wu and Xia (2016) shadow federal funds rate leads to persistent price puzzles. These puzzles arise despite inclusion of the usual suspect fixes such as commodity prices, federal funds futures and forward rate data. We find they occur at monthly and quarterly frequencies. We consider alternative indicators with the same broad monetary aggregates Keating et al. (2019) employed in their investigation of a historical sample. They provide a consistent resolution of the price puzzle and they do …

Journal of Extension

The purpose of this paper is to present a profile of middle-school-age youth who participated in a week-long experiential residential camp focused on helping campers learn about and interact with money, personal finance topics, and mainstream financial service providers. Based on pre- and post-test data, it was determined an experiential real-world camp experience can increase the financial confidence and goal-setting abilities of young people.

Futurological Fodder: On Communicating The Relationship Between Artificial Intelligence, Robotics, And Employment, Michael E. Samers Dr

Geography Faculty Publications

This article examines the debate concerning the employment implications of the so-called ‘Fourth Industrial Revolution’ (FIR) or the increasing presence of artificial intelligence and robotics in workplaces. I analyze three ‘genres’ associated with this debate (academic studies including neo-classical and heterodox/post-human approaches, the ‘gray literature’, and popular media) and I argue that together they represent ‘futurological fodder’ or discourses and knowledges that ‘perform’ the FIR and its purported consequences. I contend further that these genres involve a complex mix of ethics and politics, and I conclude with a reflection on the political implications of the FIR debate.

Herding With Heterogeneous Ability: An Application To Organ Transplantation, Stephanie De Mel, Kaivan Munshi, Soenje Reiche, Hamid Sabourian

Cowles Foundation Discussion Papers

There are many economic environments in which an object is offered sequentially to prospective buyers. It is often observed that once the object for sale is turned down by one or more agents, those that follow do the same. One explanation that has been proposed for this phenomenon is that agents making choices further down the line rationally ignore their own assessment of the object’s quality and herd behind their predecessors. Our research adds a new dimension to the canonical herding model by allowing agents to di er in their ability to assess the quality of the offered object. We …

Comparisons Of Cooking, Dietary, And Food Safety Characteristics Of Food Secure And Food Insecure Sophomores At A University In Appalachia, Hannah Boone, Melissa D. Gutschall, Alisha Farris, Kimberly Fasczewski, Don Holbert, Laura Mcarthur

Journal of Appalachian Health

Introduction: Food insecurity means lacking access to adequate, nutritious, and safe food. Collegiate food insecurity rates at ten Appalachian campuses range from 22.4% to 51.8%, and have been associated with unfavorable health and academic outcomes.

Purpose: This study compared cooking, dietary, and food safety characteristics of food secure (FS) and food insecure (FI) sophomores at a university in Appalachia in the context of the USDA definition of food security.

Methods: Data were collected using an online questionnaire. Descriptive and inferential procedures compared FS and FI sophomores (p < 0.05).

Results: Participants (n = 226) were 65.0% females, 76.1% …

Perceived Hearing Loss And Availability Of Audiologists In Appalachia, Charles B. Pudrith, Ellyn Grider, Blythe Kitner

Journal of Appalachian Health

Introduction: There is a high demand for audiologists throughout the United States. Previous research has supported an additional demand for these providers within Appalachia.

Purpose: The purpose of the study was to determine if Appalachia has a disproportionally high demand for audiologists compared to the rest of the United States.

Methods: A cross-sectional retrospective study was performed with population data from the Appalachian Regional Commission, the American Academy of Audiology, and the United States Census Bureau. County-level population-weighted averages of individuals with perceived hearing loss and number of audiologists per capita were compared between Appalachian and non-Appalachian counties. …

Estimation And Inference With Near Unit Roots, Peter C. B. Phillips

Cowles Foundation Discussion Papers

New methods are developed for identifying, estimating and performing inference with nonstationary time series that have autoregressive roots near unity. The approach subsumes unit root (UR), local unit root (LUR), mildly integrated (MI) and mildly explosive (ME) specifications in the new model formulation. It is shown how a new parameterization involving a localizing rate sequence that characterizes departures from unity can be consistently estimated in all cases. Simple pivotal limit distributions that enable valid inference about the form and degree of nonstationarity apply for MI and ME specifications and new limit theory holds in UR and LUR cases. Normalizing and …

Limit Theory For Locally Flat Functional Coefficient Regression, Peter C. B. Phillips, Ying Wang

Cowles Foundation Discussion Papers

Functional coefficient (FC) regressions allow for systematic flexibility in the responsiveness of a dependent variable to movements in the regressors, making them attractive in applications where marginal effects may depend on covariates. Such models are commonly estimated by local kernel regression methods. This paper explores situations where responsiveness to covariates is locally flat or fixed. In such cases, the limit theory of FC kernel regression is shown to depend intimately on functional shape in ways that affect rates of convergence, optimal bandwidth selection, estimation, and inference. The paper develops new asymptotics that take account of shape characteristics of the function …

On Multicointegration, Peter C. B. Phillips, Igor Kheifets

Cowles Foundation Discussion Papers

A semiparametric triangular systems approach shows how multicointegration can occur naturally in an I(1) cointegrated regression model. The framework reveals the source of multicointegration as singularity of the long run error covariance matrix in an I(1) system, a feature noted but little explored in earlier work. Under such singularity, cointegrated I(1) systems embody a multicointegrated structure and may be analyzed and estimated without appealing to the associated I(2) system but with consequential asymptotic properties that can introduce asymptotic bias into conventional methods of cointegrating regression. The present paper shows how estimation of such systems may be accomplished under multicointegration without …

Discrete Fourier Transforms Of Fractional Processes With Econometric Applications, Peter C. B. Phillips

Cowles Foundation Discussion Papers

The discrete Fourier transform (dft) of a fractional process is studied. An exact representation of the dft is given in terms of the component data, leading to the frequency domain form of the model for a fractional process. This representation is particularly useful in analyzing the asymptotic behavior of the dft and periodogram in the nonstationary case when the memory parameter d ≥ 1 2: Various asymptotic approximations are established including some new hypergeometric function representations that are of independent interest. It is shown that smoothed periodogram spectral estimates remain consistent for frequencies away from the origin in the nonstationary …

Effects Of Cyproheptadine On Body Weight Gain In Children With Nonorganic Failure To Thrive In Taiwan: A Hospital-Based Retrospective Study, Yi-Chun Lin, Hung-Rong Yen, Fuu-Jen Tsai, Chung-Hsing Wang, Lung-Chang Chien, An-Chyi Chen, Ro-Ting Lin

Epidemiology & Biostatistics Faculty Research

Failure to thrive (FTT) impairs the expected normal physical growth of children. This study aimed to evaluate the effects of cyproheptadine hydrochloride on growth parameters in prepubertal children with FTT. The medical records of prepubertal children who were newly diagnosed with FTT at China Medical University Hospital between 2007 and 2016 were retrospectively examined. The patients were divided into two groups depending on whether they had (T-group) or had not (NT-group) received cyproheptadine hydrochloride (0.3 mg/kg daily) for at least 14 days. The mean length of the treatment period was 97.22 days (range: 14–532 days). Weight, height, and body mass …

A Reassessment Of The Potential For Loss-Framed Incentive Contracts To Increase Productivity: A Meta-Analysis And A Real-Effort Experiment, Paul J. Ferraro, J. Dustin Tracy

ESI Working Papers

Substantial productivity increases have been reported when incentives are framed as losses rather than gains. Loss-framed contracts have also been reported to be preferred by workers. The results from our meta-analysis and real-effort experiment challenge these claims. The meta-analysis' summary effect size of loss framing is a 0.16 SD increase in productivity. Whereas the summary effect size in laboratory experiments is a 0.33 SD, the summary effect size from field experiments is 0.02 SD. We detect evidence of publication biases among laboratory experiments. In a new laboratory experiment that addresses prior design weaknesses, we estimate an effect size of 0.12 …

The Macroeconomic Impacts Of Entitlements, Ateeb Akhter Shah Syed, Kaneez Fatima, Riffat Naseer

The Hilltop Review

The worries expressed by Alan Greenspan that the long run economic growth of the United States will fade away due to increasing burden of entitlements motivated us to empirically investigate the impact of entitlements of key macroeconomic variables. To examine this contemporary issue, we estimate a vector error-correction model to analyze the impact of entitlements on the price level, real output, and the long-term interest rate. The results show that a shock to entitlements leads to decrease in output and lends support to the assertion made by Alan Greenspan. Several robustness checks verify that the results remain unchanged qualitatively.

Mixed-Signal Stock Splits, Ahmed M. Elnahas, Pankaj K. Jain, Thomas H. Mcinish

School of Economics and Finance Faculty Publications

We investigate CEOs who combine insider selling with stock splits, which is suspicious, because dumping stocks is inconsistent with the positive stock-split signal. Our empirical results indicate that, compared with other splits, these mixed-signal splits perform poorly and are followed by much lower buy-and-hold abnormal returns and much higher likelihoods of announcing an earnings restatement and CEO turnover in the post-split period. Our results are robust to entropy balancing and controlling for CEO characteristics, incentives, and corporate governance and highlight previously ignored agency issues around stock splits. Attention to insider trades is essential to properly interpret a stock-split signal.

China’S Geopolinomic Goals In Argentina, Chile, And Ecuador: How Chinese Resource Extraction Is Reinvigorating The Debate On Dependency, Eric Stephen Cruz

Masters Theses

The purpose of this study is to identify signs of economic dependency China creates in South America. The study builds on dependency theory by challenging China's self-categorization as a periphery nation. Using the mixed-methods case study approach, this study explores the effects of China's going out policy in South America. Specifically, the focus in the study is on asymmetric trade, increased debt, and economic dependency in the context of Argentina, Chile, and Ecuador. One of the study's significant findings is that dependency begins with access. China is efficient at securing access to natural resources through its trade arrangements, which seem …
