Linear Programming-Based Estimators In Nonnegative Autoregression, Daniel P. A. Preve

Research Collection School Of Economics

This note studies robust estimation of the autoregressive (AR) parameter in a nonlinear, nonnegative AR model. It is shown that a linear programming estimator (LPE), considered by Nielsen and Shephard (2003) among others, remains consistent under severe model misspecification. Consequently, the LPE can be used to seek sources of misspecification and to isolate certain trend, seasonal or cyclical components. Simple and quite general conditions under which the LPE is strongly consistent in the presence of heavy-tailed, serially correlated, heteroskedastic disturbances are given, and a brief review of the literature on LP-based estimators in nonnegative autoregression is presented. Finite-sample properties of …

The Impact Of Agglomeration Economies On Hospital Input Prices, Andrew Friedson, Jing Li

Research Collection School Of Economics

This paper examines the extent to which agglomeration of the hospital service industry enhances the productivity of producing health care. Specifically, we use a large set of private insurance claims from the FAIR Health database to show that an increasing spatial concentration of hospital services results in a decreased cost of obtaining intermediate medical services. We explicitly test whether the reduced cost at concentrated locations arises from the ability to share intermediate service providers. The identification relies on state variation in medical lab technician licensure requirements, which influence the cost of intermediate services only through the cost of running a …

Trade Integration, Income Divergence, And Global Imbalances, Haiping Zhang

Research Collection School Of Economics

We embed financial frictions and sector-specific minimum investment requirements (MIR) in a two-factor, two-sector, overlapping-generation model and showthat whether trade integration leads to convergence of the income levels among member states depends on their level of financial development. It helps reconcilethe mixed empirical evidence on trade integration and income dynamics in differentgroups of countries from the institutional perspective. In the recent decades, trade globalization has allowed developed countries to specialize towards the high-MIR, high-return production stages and tasks through international fragmentation of production and global sourcing. In our model, the “sectors” can be interpreted broadly as production stages and tasks. …

Unified M-Estimation Of Fixed-Effects Spatial Dynamic Models With Short Panels, Zhenlin Yang

Research Collection School Of Economics

It is well known that quasi maximum likelihood (QML) estimation of dynamic panel data (DPD) models with short panels depends on the assumptions on the initial values, and a wrong treatment of them will result in inconsistency and serious bias. The same issues apply to spatial DPD (SDPD) models with short panels. In this paper, a unified Mestimation method is proposed for estimating the fixed-effects SDPD models containing three major types of spatial effects, namely spatial lag, spatial error and space-time lag. The method is free from the specification of the distribution of the initial observations and robust against nonnormality …

Institutional Complementarity Across Countries In Bilateral Fdi Flows: Theory And Evidence, Pao-Li Chang

Research Collection School Of Economics

This paper builds a theory to characterize the comparative advantage of MNEs based in countries of different institutional qualities. It is shown that MNEs headquartered in countries of poorer state institutions will invest more in `informal institutions; and choose to undertake FDI in countries of weaker institutions. At the aggregate, MNEs on average generate more net profits in countries of weaker institutions, the poorer the institutional environment at home. I conduct an extensive test of the theory using bilateral FDI volume for 219 economies in year 2001-2010. The results indicate a statistically significant and robust institutional complementarity effect in bilateral …

New Methodology For Constructing Real Estate Price Indices Applied To The Singapore Residential Market, Liang Jiang, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This paper develops a new methodology for constructing a real estate price index that utilizes all transaction price information, encompassing both single-sales and repeat-sales. The method is less susceptible to specification error than standard hedonic methods and is not subject to the sample selection bias involved in indexes that rely only on repeat sales. The methodology employs a model design that uses a sale pairing process based on the individual building level, rather than the individual house level as is used in the repeat-sales method. The approach extends ideas from repeat-sales methodology in a way that accommodates much wider datasets. …

Intraday Value-At-Risk: An Asymmetric Autoregressive Conditional Duration Approach, Shouwei Liu, Yiu Kuen Tse

Research Collection School Of Economics

We propose to compute the Intraday Value-at-Risk (IVaR) for stocks using real-time transaction data. Tick-by-tick data filtered by price duration are modeled using a two-state asymmetric autoregressive conditional duration (AACD) model, and the IVaR is calculated using Monte Carlo simulation based on the estimated AACD model. Backtesting results for the New York Stock Exchange (NYSE) show that the IVaR calculated using the AACD method outperforms those using the Dionne et al. (2009) and Giot (2005) methods.

Adaptive Nonparametric Regression With Conditional Heteroskedasticity, Sainan Jin, Liangjun Su, Zhijie Xiao

Research Collection School Of Economics

In this paper, we study adaptive nonparametric regression estimation in the presence of conditional heteroskedastic error terms. We demonstrate that both the conditional mean and conditional variance functions in a nonparametric regression model can be estimated adaptively based on the local profile likelihood principle. Both the one-step Newton-Raphson estimator and the local profile likelihood estimator are investigated. We show that the proposed estimators are asymptotically equivalent to the infeasible local likelihood estimators [e.g., Aerts and Claeskens (1997) Journal of the American Statistical Association 92, 1536-1545], which require knowledge of the error distribution. Simulation evidence suggests that when the distribution of …

Social-Family Network And Self-Employment: Evidence From Temporary Rural–Urban Migrants In China, Junfu Zhang, Zhong Zhao

Economics

We hypothesize that individuals with a larger social-family network are more likely to choose self-employment. We test this hypothesis using data on temporary rural–urban migrants in China. The size of a migrant’s social-family network is measured by the number of relatives and friends this migrant greeted during the past Spring Festival. After controlling for endogeneity using an instrumental variable approach, our results show that a rural–urban migrant with a larger social-family network is more likely to be self-employed. This finding is robust to alternative model specifications and various restrictions on the estimation sample.

Competition And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu

Research Collection School Of Economics

This paper provides a quantitative analysis of gains from trade for China over the period of 1995-2004, which was when China's openness drastically improved. We decompose gains from trade in two ways. First, we disentangle pro-competitive effects from a traditional Ricardian effect. Second, we separate the effect due to tariff reductions from that due to reductions in non-tariff trade costs. Our quantitative analysis shows that the pro-competitive effects account for 25.4% of the total welfare gains from trade, whereas the allocative efficiency alone accounts for 22.3%. We also find that tariff reductions account for about 31.6% of reductions of overall …

Cross-Listing Performance And Insider Ownership: The Experience Of U.S. Investors, Omar A. Esqueda, Dave Jackson

School of Economics and Finance Faculty Publications

Insider-owned firms pursue U.S. cross-listings following periods of extraordinary performance. However, the long-run post-cross-listing abnormal returns become negative only for insider-controlled cross-listings. We find that the Sarbanes–Oxley Act (SOX) has mitigated the market-timing attempts as negative abnormal returns are limited to the pre-SOX period, supporting a cross-listing bonding benefit after U.S. securities regulation was enhanced. In addition, investors anticipate future operating performance as stock returns incorporate forthcoming operating outcomes one and two years ahead. Whereas capital-raising cross-listings show better operating performance than non-capital-raising, the returns of capital-raising firms are more sensitive to the potential agency problems created by insider-ownership.

The Job Of Human Capital: What Occupational Data Reveal About Skill Sets, Economic Growth And Regional Competitiveness, Lillian Frances Stewart

ETD Archive

A region's workforce has been described as its greatest asset. Guided by human capital theory and new growth theory, regions have pursued economic development policies to increase the number of college-educated workers and expand the pool of STEM -- science, technology, engineering, and math -- talent. Academic literature and policy interventions have focused on a region's human capital in terms of educational attainment instead of a more fine-grained definition of human capital based on skills and competencies. This dissertation integrates economic and business theory and combines three federal databases to explore regional human capital assets. Findings suggest that policymakers may …

The Social Relations Of Consumption: Corporate Law And The Meaning Of Consumer Culture, David G. Yosifon

BYU Law Review

A mature assessment of the society we are making for ourselves, and the legacy we are leaving to the future, must come to terms with consumer culture. Theoretical discourse, as well as common experience, betray persistent ambiguity about what consumerism means to and says about us. In this Article, I argue that this ambiguity can in part be explained by examining the social relations of consumption in contemporary society. These involve, crucially, the relationship between producer and consumer that is dictated by corporate governance law, and embodied in the decision-making dynamics of the directors who command corporate operations. The enigmatic …

Monopsony Exploitation In Professional Sport: Evidence From Major League Baseball Position Players, 2000-2011, Brad R. Humphreys, Hyunwoong Pyun

Economics Faculty Working Papers Series

Some professional athletes still face monoposony power in labor markets, underscoring the importance of estimating players' marginal revenue product (MRP) to assess its effects. We introduce two new empirical approaches, spline revenue functions and fixed-effects stochastic production functions, into the standard Scully (1974) approach to MRP estimation, and calculate Monoposony Exploitation Ratios (MERs) for position players in Major League Baseball over the 2001-2011 seasons. Estimates indicate that MERs are about 0.89 for rookie players, 0.75 for arbitration eligible players, and 0.21 for free agents. Recent collective bargaining agreements have reduced MERs for free agents, but had no effect on MERs …

Financing Terrorism: A Look At The Past, Present, And Future Of Defunding Terror Organizations, Mitchell Wasmund

University Honors Program

Terrorism is a major problem facing governments across the globe in the 21st century. Terror organizations, domestic and international, are complex and vary in structure as well as how they are financed. By using various governmental and journalistic resources, this paper will examine four different terror organizations in how they are operated and financed. It will focus on what are the current practices by law enforcement officials to stop the sources of terror organizations’ funds. This paper will also examine future areas of concern related to where terror organizations will receive their financing in the future. The impacts of economic …

In the process it clarifies issues that are often muddled in the steady-state and de-growth literatures.

Theory Of Mind Predicts Cooperative Behavior, Gregory Deangelo, Bryan C. Mccannon

Economics Faculty Working Papers Series

Explanations for cooperation in Prisoner’s Dilemma games (PD) have generated significant interest. While institutional explanations, such as the role of repeated interactions and communication, have offered considerable explanatory ability, a psychological measure of Theory of the Mind (ToM) – Reading the Mind in the Eyes – of an individual’s ability to process social and emotional cognition offers new insights. Using this measure, we examine how ToM explains (un)cooperative behavior in a standard PD game. We find that subjects who have higher ToM are less cooperative in PD games and extract higher payoffs.

Managerial Segmentation Of Service Offerings In Work Commuting, Steven D. Silver

Faculty Publications

This study reports an implementation of procedures that multivariate methodology make available to assess the relative importance of attributes of service offerings to work commuters. Adaptive choice conjoint analysis was used to derive the importance weights of attributes in available service offering to a commuter sample. A clustering procedure was then used to define homogeneous sub-groups of the sample and the combination of demographic differences that discriminate clusters. Results of this assessment are used to indicate how a market in workcommuting can be segmented on the basis of user indications of the importance of attributes of service offerings.

Strategic Generation Bidding Using A Learning Algorithm Through Updates Of Supply Offer Selection Propensities, Sriram Raghavan, Jhi Young Joo

Economics Faculty Research & Creative Works

This paper discusses a novel bidding strategy of a generation company (genco) in an hourly day-Ahead market. In the proposed method, a genco learns the returns of supply offers and adapts its strategy, accordingly, based on the Variant Roth-Erev (VRE) reinforcement learning algorithm. Every supply offer submitted to the market receives a profit at the end of each day and is strategically updated for the next day based on this profit. The novelty of our proposed method is that every supply offer has a propensity (an inclination or a tendency) to be selected associated with it. The propensity is updated …

Helminth Infection, Fecundity, And Age Of First Pregnancy In Women, Aaron D. Blackwell, Marilyne D. Tamayo, Bret Beheim, Benjamin C. Trumble, Jonathan Stieglitz, Paul L. Hooper, Melanie Martin, Hillard Kaplan, Michael Gurven

ESI Publications

Infection with intestinal helminths results in immunological changes that influence the odds of comorbid infections, and might also affect fecundity by inducing immunological states supportive of conception and pregnancy. Here we investigate associations between intestinal helminths and fertility in human females, utilizing nine years of longitudinal data from 986 Bolivian forger-horticulturalists, experiencing natural fertility and a 70% helminth prevalence. We find that different species of helminth are associated with opposing effects on fecundity. Infection with roundworm (Ascaris lumbricoides) is associated with earlier first births and shortened interbirth intervals, while infection with hookworm is associated with delayed first pregnancy and extended …

Using Linked Survey And Administrative Data To Better Measure Income: Implications For Poverty, Program Effectiveness And Holes In The Safety Net, Bruce D. Meyer, Nikolas Mittag

Upjohn Institute Working Papers

We examine the consequences of underreporting of transfer programs in household survey data for several prototypical analyses of low-income populations. We focus on the Current Population Survey (CPS), the source of official poverty and inequality statistics, but provide evidence that our qualitative conclusions are likely to apply to other surveys. We link administrative data for food stamps, TANF, General Assistance, and subsidized housing from New York State to the CPS at the individual level. Program receipt in the CPS is missed for over one-third of housing assistance recipients, 40 percent of food stamp recipients, and 60 percent of TANF and …

Estimating Hispanic-White Wage Gaps Among Women: The Importance Of Controlling For Cost Of Living, Peter Mchenry, Melissa Mcinerney

Upjohn Institute Working Papers

Despite concern regarding labor market discrimination against Hispanics, previously published estimates show that Hispanic women earn higher hourly wages than white women with similar observable characteristics. This estimated wage premium is likely biased upwards because of the omission of an important control variable: cost of living. We show that Hispanic women live in locations (e.g., cities) with higher costs of living than whites. After we account for cost of living, the estimated Hispanic-white wage differential for non-immigrant women falls by approximately two-thirds. As a result, we find no statistically significant difference in wages between Hispanic and white women in the …

A Theoretical And Methodological Framework To Analyze Long Distance Pleasure Travel, Vijayaraghavan Sivaraman

USF Tampa Graduate Theses and Dissertations

The United States (US) witnessed remarkable growth in annual long distance travel over the past few decades. Over half of the long distance travel in the US is made for pleasure, including visiting friends and relatives (VFR) and leisure activities. This trend could continue with increased use of information and communication technologies for socialization, and enhanced mobility being achieved using fuel-efficient (electric/hybrid) and technology enhanced vehicles. Despite these developments, and recent interest to implement alternate mass transit options to serve this market, not much exists on the measurement, analysis and modeling of long distance pleasure travel in the U.S.

Optimal Social Assistance And Unemployment Insurance In A Life-Cycle Model Of Family Labor Supply And Savings, Peter Haan, Victoria Prowse

Upjohn Institute Working Papers

We analyze empirically the optimal design of social insurance and assistance programs when families obtain insurance by making labor supply choices for both spouses. For this purpose, we specify a structural life-cycle model of the labor supply and savings decisions of singles and married couples. Partial insurance against wage and employment shocks is provided by social programs, savings, and the labor supplies of all adult household members. The optimal policy mix focuses mainly on Social Assistance, which provides a permanent universal household income floor, with a minor role for temporary earnings-related Unemployment Insurance. Reflecting that married couples obtain intra-household insurance …

Accounting For Indirect Costs In Public Health Cost Analyses, Melanie D. Whittington, Adam Atherly, Lisa Vanraemdonck

Frontiers in Public Health Services and Systems Research

Background. There is a gap in research regarding the resources needed to deliver public health activities, which inhibits informed decision making around investments in public health and the allocation of funds among activities. When conducting cost analyses in public health, it is important to include costs from all cost components, including personnel, non-personnel, and indirect costs. However, defining, identifying, and measuring indirect costs is challenging and can impede studies of this type. Purpose. The purpose of this pilot study is to create a catalog of the methodologies public health researchers have used to account for indirect costs. Methods. We surveyed …

The Pros And Cons Of Sick Pay Schemes: Testing For Contagious Presenteeism And Shirking Behavior, Stefan Pichler, Nicolas R. Ziebarth

Upjohn Institute Working Papers

This paper proposes a test for the existence and degree of contagious presenteeism and negative externalities in sickness insurance schemes. First, we theoretically decompose moral hazard into shirking and contagious presenteeism behavior and derive testable conditions. Then, we implement the test exploiting German sick pay reforms and administrative industry-level data on certified sick leave by diagnoses. The labor supply adjustment for contagious diseases is significantly smaller than for noncontagious diseases. Lastly, using Google Flu data and the staggered implementation of U.S. sick leave reforms, we show that flu rates decrease after employees gain access to paid sick leave.
