Approximate Solutions Of Walrasian Equilibrium Inequalities With Bounded Marginal Utilities Of Income, Donald J. Brown

Cowles Foundation Discussion Papers

Recently Cherchye et al. (2011) reformulated the Walrasian equilibrium inequalities, introduced by Brown and Matzkin (1996), as an integer programming problem and proved that solving the Walrasian equilibrium inequalities is NP-hard. Brown and Shannon (2002) derived an equivalent system of equilibrium inequalities, i.e., the dual Walrasian equilibrium inequalities. That is, the Walrasian equilibrium inequalities are solvable iff the dual Walrasian equilibrium inequalities are solvable. We show that solving the dual Walrsian equilibrium inequalities is equivalent to solving a NP-hard minimization problem. Approximation theorems are polynomial time algorithms for computing approximate solutions of NP-hard minimization problems. The primary contribution of this …

Adaptive Testing On A Regression Function At A Point, Timothy B. Armstrong

Cowles Foundation Discussion Papers

We consider the problem of inference on a regression function at a point when the entire function satisfies a sign or shape restriction under the null. We propose a test that achieves the optimal minimax rate adaptively over a range of Holder classes, up to a log log n term, which we show to be necessary for adaptation. We apply the results to adaptive one-sided tests for the regression discontinuity parameter under a monotonicity restriction, the value of a monotone regression function at the boundary, and the proportion of true null hypotheses in a multiple testing problem.

The Role Government Should Play In The American Recovery And Reinvestment Act 2009, Jungmi Bang

Maurer Theses and Dissertations

The purpose of this research is to determine the most effective way to administer an economic stimulation act and what role the government should play. More specifically, the paper will discuss administrative problems and limitations, such as the government’s possible disengagement from the real market stake holders’ assessment in the ARRA and will provide possible solutions to eliminate or minimize those defects. Ultimately, the research seeks to satisfy the real market stake holders’ expectation by analyzing the pros and cons of the ARRA, and by comparing Korea’s administrative approach to adopting an economic stimulation plan in the real market with …

Risk Preferences And Prenatal Exposure To Sex Hormones For Ladinos, Diego Aycinena, Rimvydas Baltaduonis, Lucas Rentschler

Economics Faculty Publications

Risk preferences drive much of human decision making including investment, career and health choices and many more. Thus, understanding the determinants of risk preferences refines our understanding of choice in a broad array of environments. We assess the relationship between risk preferences, prenatal exposure to sex hormones and gender for a sample of Ladinos, which is an ethnic group comprising 62.86% of the population of Guatemala. Prenatal exposure to sex hormones has organizational effects on brain development, and has been shown to partially explain risk preferences for Caucasians. We measure prenatal exposure to sex hormones using the ratio of the …

El Mal De Chagas Y Su Potencial De Eliminación, Eileen Stillwaggon

Economics Faculty Publications

La Asamblea Mundial de la Salud ha elegido algunas enfermedades como blancos para la eliminación. Hay mucha esperanza y una alta probabilidad de que varias enfermedades, recientemente llamadas desatendidas, sean eliminadas en las próximas décadas. Vamos a presenciar el fin de la transmisión de la dracunculiasis, la filariosis linfática, la poliomielitis, y en las Américas por lo menos, la oncocercosis. Ya se ven éxitos significativos como la cuasi erradicación de la dracunculiasis y paso importantes en contra de otras aflicciones. [Original Spanish version]

The World Health Assembly has chosen some diseases as targets for elimination. There is much …

Unrecognized States: A Theory Of Self-Determination And Foreign Influence, Kristina Buzard, Benjamin A.T. Graham, Ben Horne

Economics - All Scholarship

Unrecognized states are characterized by stagnant or crumbling economies and political instability, often serve as havens for illicit trade, and challenge the territorial sovereignty of recognized states. Their persistence is both intellectually puzzling and normatively problematic, but unrecognized statehood can be a remarkably stable outcome, persisting for decades. Our four-player model reveals that unrecognized statehood emerges as an equilibrium outcome when a patron state is willing and able to persistently invest resources to sustain it. We assess options available to actors in the international community who seek to impose their preferred outcomes in these disputes and find that, although sanctions …

Learning Tastes Through Social Interaction, Alice Hsiaw

Economics Department Working Papers

This paper offers an information-based model of social interaction, and analyzes optimal investment and pricing of services that facilitate interaction in a duopoly. Agents have uncertainty over their preferences but are aware that they are correlated with others’, so there exists an incentive to communicate with others in the population. When a firm’s good can be bundled with a coordination mechanism for its consumers, its value is endogenously determined due to a consumption externality. Although this mechanism increases total surplus, it is underprovided and consumer surplus decreases.

Nonmedical Prescription Drug Use: Theory And Policy Implications, Gabriele Camera, Bryan Engelhardt

Economics Department Working Papers

The illicit nonmedical use of prescription drugs is studied in a model where individuals with imperfectly observable health conditions seek prescription drugs for either medical or nonmedical reasons. The equilibrium number of medical and nonmedical users is endogenous and depends on economic and non-economic barriers to drugs consumption, such as pricing, health care costs, refill policies, monitoring programs, and the medical community’s prescription standards. The results show policies centered around raising economic barriers reduces nonmedical use but inhibits medical use due to imperfect screening. Alternatively, the results suggest a national drug registry may be more effective at preventing nonmedical use.

Effects Of Health Expenditures On Population Age Distribution And Labor Force Participation Rates: Empirical And Comparative Analysis, Jassim M. H. Al-Jebory

Masters Theses

Baby boom and population aging are the main features of the world population that are leading to child and elderly people in the labor force. Categorizing the world into low and high-income countries, the baby boom and child labor can be found in low-income countries, while population aging and elderly people in the labor force can be found in high-income countries. The cause of these features is declining rates of population and labor force ages 15-64, which is the most productive and active proportion. Health expenditures is one of the main factors that is associated with undesired trends of population …

Paying To Put Out Fires, Kevin F. Hallock

Economics Faculty Publications

There is surprisingly little academic work on the compensation of firefighters. This may be, in part, because their wages are often set by collective bargaining agreements and that those paid as firefighters are regularly paid by seniority. But many aspects of the labor market can still be studied through this interesting occupation, including labor unions, compensation for job risk and even volunteerism. Consider the mountains of papers on Fortune 500 CEOs relative to the number (500) of employees doing this job in the US. In contrast, consider the tiny number of papers on firefighters relative to the large numbers who …

Cash On The Table? A Behavioral Analysis Of Refund Claimants And Annuitants In The Illinois Teachers' Retirement System, Martin F. Lueken

Graduate Theses and Dissertations

This dissertation documents pension benefit choices made by public school teachers enrolled in the Illinois Teachers' Retirement System (TRS), where they choose between taking a lump-sum withdrawal of their refundable contributions and deferring a pension benefit. The analysis explores the extent to which vested teachers enrolled in TRS separate from service with positive pension wealth, estimates how much money is "left on the table" at a conventional discount rate, and investigates what types of teachers display higher or lower discount rates as indicated by cashout patterns. To control for the relative attractiveness between choices, the analysis relies on three central …

Trading Income And Bank Charter Value During The Financial Crisis: Does Derivatives Dealer Designation Matter?, Peter V. Egly, Jun Sun

School of Economics and Finance Faculty Publications

Derivative markets have exploded over the last decade, remained active in the midst of the 2007-2009 financial crises and continue to be dominated by a small group of bank holding companies (BHC). BHC motives for derivative usage are usually tied to hedging purposes (balance sheet risk management), trading purposes (profit motives) or some combination thereof. This paper examines the relationship between derivative trading income and bank charter value for 27 BHC between 2001Q1-2011Q3. We find that the impact of derivative trading income on bank charter value, using Tobin’s Q, is very small and seems to be tied to BHCs derivatives …

An Alternative View To The Cause Of Market Failures: A Dynamic Approach, Salvador Contreras

School of Economics and Finance Faculty Publications

This paper presents an alternative view to the cause and size of market failures. The work here suggest that the size of the market failure is not man made per se but rather given a full set of initial conditions it is endogenous to the dynamical forces at play. It is shown that the level and variance of market failures is tied to the location of the steady state (i.e. level of development). The paper finds that only changes to the location of the steady state produces changes to the potential level of the market failure. This paper …

Financial Crisis And The Supply Of Corporate Credit, Jorge Santiago Emmanuel Barraza

Graduate Theses and Dissertations

This dissertation consists of three essays that study the relationship between distress and credit and the role this relationship has in determining corporate investment and economic activity. The first essay studies the supply of credit during the recent financial crisis. It shows that distress in the banking sector led to bank credit rationing, which a portion of nonfinancial borrowers palliated by migrating to the public market for credit. The overall reduction in credit, however, was followed by a severe drop in corporate investment, which in time led to a fall in the levels of aggregate production.

The second essay examines …

Essays In Pro-Social Behavior, Joshua R. Foster

Graduate Theses and Dissertations

This dissertation examines individuals' actions to improve social outcomes when unrecoverable investments are necessary. Situations involving non-pecuniary and pecuniary investments are considered. In the former, the prerequisite of real effort - a non-pecuniary, unrecoverable investment - is examined when said effort determines an individual's ability to procure their preferred social outcome. Theoretical predictions over an individual's effort provision are based on their revealed preferences for the social distribution of wealth according to the general axiom of revealed preference (GARP). Laboratory experiments reveal that individuals' effort provisions do not support the assumption of stable preferences (transitivity) of wealth distribution. Specifically, individuals …

Economic Impacts Of Increased Corporate Average Fuel Economy (Cafe) Standards, Ann K. Hunter-Pirtle

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The Renewable Fuel Standard (RFS) mandates that U.S. transportation fuel producers blend specific volumes of ethanol and other biofuels with fossil fuels to spur U.S. biofuel production and to minimize foreign oil imports. Ethanol is more corrosive to auto engines than gasoline, and although vehicles manufactured since 2001 are approved to use up to a 15% ethanol blend (E15) (Naylor & Falcon, 2011), E10 is much more widely available. Ethanol producers therefore face a so-called blend wall at 10 percent—a maximum amount of ethanol that is usable domestically based on the demand for gasoline.

Meanwhile, gasoline demand in the U.S. …

Promotional Reviews: An Empirical Investigation Of Online Review Manipulation, Dina Mayzlin, Yaniv Dover, Judith Chevalier

Dartmouth Scholarship

Firms' incentives to manufacture biased user reviews impede review usefulness. We examine the differences in reviews for a given hotel between two sites: Expedia.com (only a customer can post a review) and TripAdvisor.com (anyone can post). We argue that the net gains from promotional reviewing are highest for independent hotels with single-unit owners and lowest for branded chain hotels with multi-unit owners. We demonstrate that the hotel neighbors of hotels with a high incentive to fake have more negative reviews on TripAdvisor relative to Expedia; hotels with a high incentive to fake have more positive reviews on TripAdvisor relative to …

International Reserves Before And After The Global Crisis: Is There No End To Hoarding?, Joshua Aizenman, Yin-Wong Cheung, Hiro Ito

Economics Faculty Publications and Presentations

We evaluate the global financial crisis (GFC) and the structural changes of recent years that have been associated with new patterns of hoarding international reserves. We confirm that the determining factors of international reserves are evolving with developments in the global economy. From 1999–2006, the pre-GFC period, gross saving is associated with higher international reserves in developing and emerging markets. An outward direct-investment effect is consistent with the view of diverting international assets from the international reserve account, the “Joneses’ effect” lends support to the rivalry hoarding motivation, and commodity price volatility induces hoarding against uncertainty. During the 2007–2009 GFC, …

Ageism, Honesty, And Trust, Eric Schniter, Timothy W. Shields

ESI Publications

Age-based discrimination is considered undesirable, yet we know little about age stereotypes and their effects on honesty and trust. To investigate this aspect of ageism, we presented older adults (over age 50) and younger adults (under age 25) with incentivized belief elicitation tasks about anticipated interaction behaviors and then a series of same, different, and unknown-aged group interactions in a strategic-communication game. All adults shared consensual stereotypes about uncooperative younger adults and cooperative older adults that demonstrated “wisdom of crowds”. While the out-group was consistently stereotyped as relatively different and more dishonest and suspicious than observed to be, the in-group …

Utilization Of Savings And Credit By Household Characteristics In Uganda And The Implications For Linkage Banking Programs, Kathryn Oswald

All Theses

The objectives of this thesis are to 1) estimate the overall distributions of household characteristics, 2) estimate the overall distributions of access to savings and credit products, and 3) determine the relationship between household characteristics and access to savings and credit products from various formal, semi-formal, and informal institution types. The goal of this thesis is to provide a direction for future linkage banking programs by finding which household characteristics should be targeted by this type of program. Panel data published by World Bank from the Uganda National Household Survey (UNHS) collected in 2005/06 and the Uganda National Panel Survey …

Extension Assessments Of Farmer Interest In And Uses Of Climate Forecasts In Florida, North Carolina, And South Carolina, Alan Hooper

All Theses

Farmers can reduce the risks associated with climate variability by using climate forecasts. Extension personnel, as knowledgeable informants about farmers, can assess farmer interest in and uses of climate forecasts in agricultural decision making. Three surveys of extension personnel were conducted in Florida, North Carolina, and South Carolina to assess, among other things, farmer interest in and uses of climate forecasts. Models of conditional probabilities are estimated with data from the surveys to show how extension assessments depend on characteristics of the extensionist and her clientele. An extensionist with more than six years of experience is more likely to think …

The main focus is on education finance in New York State, but general research findings in education and education policy issues in several other states are also discussed. John Yinger, Professor of Economics and Public Administration at the Maxwell School, Syracuse University is the author of most of these essays, although a few are written by or co-authored with other scholars.

The Spatial Polish Wage Curve With Gender Effects: Evidence From The Polish Labor Survey, Badi H. Baltagi, Bartlomiej Rokicki

Center for Policy Research

This paper reconsiders the Polish wage curve using individual data from the Polish Labor Force Survey (LFS) at the 16 NUTS2 level allowing for spatial spillovers between regions. In addition it estimates the total and gender-specific regional unemployment rate elasticities on individual wages. The paper finds significant spatial unemployment spillovers across Polish regions. In addition, it finds that the results for the Polish wage curve are sensitive to gender-specific regional unemployment rates. This is especially true for women.

Qualitative And Quantitative Analysis Of Wage Differentials Using Nonparametric Methods, Eric Makela

All Dissertations

The vast empirical literature on wage differentials reflects extreme interest in the subject from economists, social scientists, and policymakers alike. A review of the literature reveals two noticeable shortcomings. First, nearly all past studies have assumed a linear relationship between earnings and worker characteristics without consideration as to the potential specification error this imposes on their estimates. Second, researchers have generally focused on simple mean effects rather than estimating the effects of characteristics and wage rates on earnings distributions as a whole. Using data from the American Community Survey, this Dissertation addresses both issues with a simple nonparametric approach, and …

Essays In International Economics, Eyup Dogan

All Dissertations

This Dissertation consists of three chapters. These chapters use the power of the gravity model widely employed in the international economics literature. The first chapter investigates how economic integration agreements impact countries' local technology, wages, prices and market access, and how to aggregate these effects to compute the changes in countries' welfare. By examining 16 countries that have harmonized with the European Union since 1980, we show that almost all of the participating countries experience welfare gains as a result of signing integration agreements with the European Union. The objective of the second chapter is to explain the determinants of …

Essays On The Political Geography Of The United States Of America, Wesley Harris

All Dissertations

The Correlation between income and voting is very different based on what part of the country a voter resides. In rural areas, there is a strong and negative correlation between income and probability of voting for a Democratic Presidential Candidate, while in urban areas, the correlation is much weaker. This paper shows that once you control for not only individual specific characteristics of voters but also geographic characteristics such as racial diversity, population density, and economic diversity, the regional differences between the effects of income on voting disappears. One potential explanation for this geographical significance is in urban areas the …

Wage A Measured Battle Against The Bottle, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

In a commentary, SMU Associate Professor of Law and Nominated Member of Parliament Eugene Tan believed that there are legitimate and pressing concerns to justify the close scrutiny of the existing regime on alcohol sale and consumption. He felt that the authorities could leverage market research data to understand the drinking culture and norms here and generate nuanced regulatory responses to alcohol sale and consumption. The insights gleaned from such research could aid our understanding of the dynamics of the drinking culture here. Associate Prof Tan added that the key policy challenge in the review process is to tackle the …

Economic Voting In The Developing World, Rafael Oganesyan

UNLV Theses, Dissertations, Professional Papers, and Capstones

A plethora of ink has been spilled demonstrating the relationship between economics and voter behavior. Unfortunately, the overwhelming majority of scholarship has concentrated on the empirical assessment of economic voting within the context of developed countries. The present thesis widens the scope of study by testing the applicability of the classic economic voting theory (CEVT) strictly within developing countries. The results suggest that while voters in developing countries do take the economy into account, they do so in a manner that's partially different from what CEVT predicts. Voters in developing countries simultaneously assume both retrospective sociotropic and prospective sociotropic characteristics. …

Bayesian Testing Volatility Persistence In Stochastic Volatility Models With Jumps, Xiaobin Liu, Yong Li

Research Collection School Of Economics

Whether or not there is a unit root persistence in volatility of financial assets has been a long-standing topic of interest to financial econometricians and empirical economists. The purpose of this article is to provide a Bayesian approach for testing the volatility persistence in the context of stochastic volatility with Merton jump and correlated Merton jump. The Shanghai Composite Index daily return data is used for empirical illustration. The result of Bayesian hypothesis testing strongly indicates that the volatility process doesn’t have unit root volatility persistence in this stock market.
