Does Faculty Tenure Improve Student Graduation Rates?, G. Thomas Sav

Economics Faculty Publications

The primary objective of this paper is to determine whether tenure in comparison to non-tenure faculty employment is efficient in producing the academic success of university students. A stochastic production frontier is estimated for university graduation rates while the inefficiency specification includes measures of tenured, tenure-track, and non-tenure track faculty employment. Using panel data for U.S. doctoral and master level public universities, the evidence indicates that the employment status does matter and that increases in the pro- portion of tenured faculty employment lead to efficiency gains in graduation rates. Effects of tenure-track and non-tenure track faculty are somewhat mixed with …

Selective Asymmetric Capital Financing Behavior: Preference Towards Equity Financing, Donald Lien, Melody Lo, Jinlan Ni

Economics Faculty Publications

Using data from 1,217 publicly traded Chinese companies from 1994–2006, we show that the capital financing behavior of Chinese firms deviates substantially from the pecking order theory in that equity issues are always the preferred financing source for funding requirements. We further document the existence of a stylized asymmetric financing pattern — equity issues are used much more heavily over debt issues under the condition of a fund flow surplus versus a fund flow deficit, which is the result of Chinese firms selecting the degree of inherent equity-issue preference feasible to pursue given their fund flow condition.

Minority Serving College And University Cost Efficiencies, G. Thomas Sav

Economics Faculty Publications

Problem Statement:

Higher education minority enrollment growth has far outstripped white non-minority growth in the United States. Minority serving colleges and universities have disproportionately attended to that growth and will continue to play a critical role in providing minority educational opportunities in a knowledge based and globally diverse economy. However, they will face new and challenging budgetary and managerial reforms induced by the global financial crisis. As a result, they will be pressured to operate in the future with greater cost efficiency.

Approach:

Panel data pertaining to minority serving colleges and universities was used along with stochastic frontier analysis to …

Are Low Wages Risk Factors For Hypertension?, J. Paul Leigh, Juan Du

Economics Faculty Publications

Objective: Socio-economic status (SES) is strongly correlated with hypertension. But SES has several components, including income and correlations in cross-sectional data need not imply SES is a risk factor. This study investigates whether wages-the largest category within income-are risk factors. Methods: We analysed longitudinal, nationally representative US data from four waves (1999, 2001, 2003 and 2005) of the Panel Study of Income Dynamics. The overall sample was restricted to employed persons age 25-65 years, n = 17 295. Separate subsamples were constructed of persons within two age groups (25-44 and 45-65 years) and genders. Hypertension incidence was self-reported based on …

Formal And Informal Care: An Empirical Bayesian Analysis Using The Two-Part Model, Juan Du

Economics Faculty Publications

Informal care provided to the elderly by their children is proposed as a less expensive alternative to institutional long-term care. This paper explores how the elderly's consumption of medical care changes in response to changes in the informal care they receive from their children. Many earlier studies have ignored both the endogeneity of informal care and the complicated nature of health care utilization data. This paper develops a two-part model with informal care treated as an endogenous regressor and imposes exclusion restrictions on the selection process. The model is fitted using the Bayesian Markov Chain Monte Carlo (MCMC) methods, in …

Is There Deadweight Loss In Holiday Rewards?, Kevin F. Hallock

Economics Faculty Publications

An interesting and provocative study was conducted by Joel Waldfogel of the University of Minnesota some 20 years ago. He wrote "The Deadweight Loss of Christmas." Waldfogel was not only discussing Christmas but noted that the ideas could apply to other holidays with gift-giving rituals. The study noted that although gift giving is generally applauded by economists since it is a way to help the macro economy, there is another side to the story. A problem with gift giving (or non-monetary rewards) is that the gift giver often does not perfectly know the preferences of the person receiving the gift. …

Pay System Gender Neutrality, Kevin F. Hallock

Economics Faculty Publications

It was Francine Blau's "Equal Pay in the Office" (1977) that laid out some of the seminal research on gender differences in labor market outcomes. Blau and other pioneering researchers established decades ago that the gender pay gap (then around 40%) could not be ignored by academic economists. Many organizations are concerned with whether their individual pay systems are gender neutral, but it is not easy to test robustly a pay system's gender neutrality. To build such a test requires consideration of several issues, including control variables, occupational patterns, statistical specifications, and the often-overlooked difference between wage and salary income …

China’S Energy Inefficiency: A Cross-Country Comparison, Chu Wei, Jinlan Ni, Manhong Sheng

Economics Faculty Publications

This paper constructs a total-factor energy technical efficiency index using the data envelopment analysis (DEA) method following the total factor productivity framework. We then compare energy technical efficiency across 156 countries from 1980 to 2007. The results show that China's energy efficiency considerably trails other countries’ although it has made significant gains within the last 28 years. Further analysis indicates that scale inefficiency rather than pure technical efficiency contributes to China's energy inefficiency.

Say On Pay And Compensation Design, Kevin F. Hallock

Economics Faculty Publications

Say on pay is demanding far more time and energy than expected, and its full impact on the world won't be known for years. The 2011 proxy season was the first time publicly traded firms in the U.S. were required by law to solicit from their shareholders advisory yes or no votes on the pay package awarded to the CEO. In every industry, the median CEO received a raise (positive year-on-year change) in total CEO compensation. The mix of pay shifted some. For example, in the communications industry, the average share of total compensation paid in salary fell by 6.53 …

Hiv And Concurrent Sexual Partnerships: Modelling The Role Of Coital Dilution, Larry Sawers, Alan G. Isaac, Eileen Stillwaggon

Economics Faculty Publications

Background: The concurrency hypothesis asserts that high prevalence of overlapping sexual partnerships explains extraordinarily high HIV levels in sub-Saharan Africa. Earlier simulation models show that the network effect of concurrency can increase HIV incidence, but those models do not account for the coital dilution effect (nonprimary partnerships have lower coital frequency than primary partnerships).

Methods: We modify the model of Eaton et al (AIDS and Behavior, September 2010) to incorporate coital dilution by assigning lower coital frequencies to non-primary partnerships. We parameterize coital dilution based on the empirical work of Morris et al (PLoS ONE, December …

Publicly Vs. Privately Controlled Higher Education Costs: Panel Data Estimates, G. Thomas Sav

Economics Faculty Publications

More so now than ever, budgetary problems and widespread reforms are generating questions regarding higher education costs among publicly controlled compared to privately controlled colleges and universities. Past studies have offered scale and scope estimates anchored in 1995 and earlier cross sectional data that could contain omitted variable biased. In contrast, this paper employs panel data spanning the 2005 through 2009 years to estimate a multiproduct cost function and scale and scope economies separately for public and private sector colleges and universities. The two-way fixed effects results indicate the presence of significant institutional and time effects. Overall, the findings suggest …

Linking Compensation And Job Losses During A Recession, Kevin F. Hallock

Economics Faculty Publications

For more than 60 years, no permanent Lincoln Electric employee has been laid off for lack of work. 2010 marked the 10th consecutive year year that the company increased its dividend and stock price gains have fairly consistently outperformed the S&P 500 during the past five years. For most organizations, when costs need to be cut, shedding some workers is part of the solution. Work Sharing Unemployment Insurance tries to mitigate the negative repercussions of layoffs. Under WSUI, workers are eligible for a prorated fraction of unemployment insurance benefits. Proponents of WSUI contend that hiring, firing, and retraining costs are …

Does That Pay Practice Really Have Any Impact?, Kevin F. Hallock

Economics Faculty Publications

Few organizations take the time to credibly study whether some pay, benefits, work-life balance or other total rewards practices have any impact on the organizations' bottom line or employee outcomes like productivity or turnover. It's too difficult to do well, organizations don't actually want to know the answer, and/or organizations don't have the know-how or time. One successfully executed, evidence-based study of a new compensation practice is Safelite AutoGlass. Edward Lazear compared the productivity change worker by worker, for only those employees present under both pay arrangements. Lazear found that not only did productivity increase after the change from hourly …

Empirical Methods For Predicting Student Retention- A Summary From The Literature, Matt Bogard

Economics Faculty Publications

The vast majority of the literature related to the empirical estimation of retention models includes a discussion of the theoretical retention framework established by Bean, Braxton, Tinto, Pascarella, Terenzini and others (see Bean, 1980; Bean, 2000; Braxton, 2000; Braxton et al, 2004; Chapman and Pascarella, 1983; Pascarell and Ternzini, 1978; St. John and Cabrera, 2000; Tinto, 1975) This body of research provides a starting point for the consideration of which explanatory variables to include in any model specification, as well as identifying possible data sources. The literature separates itself into two major camps including research related to the hypothesis testing …

Empirical Methods-A Review: With An Introduction To Data Mining And Machine Learning, Matt Bogard

Economics Faculty Publications

This presentation was part of a staff workshop focused on empirical methods and applied research. This includes a basic overview of regression with matrix algebra, maximum likelihood, inference, and model assumptions. Distinctions are made between paradigms related to classical statistical methods and algorithmic approaches. The presentation concludes with a brief discussion of generalization error, data partitioning, decision trees, and neural networks.

Pay Ratios And Pay Inequality, Kevin F. Hallock

Economics Faculty Publications

Some argue that reporting the ratio of CEO pay to that of the median-compensated worker in the organization is useful since it highlights the sometimes large discrepancy between the pay of an average worker and that of corporate executives. One argument against reporting the ratio of CEO pay to median worker pay is that this is much more difficult to calculate in practice than in theory. The hourly earnings of workers at the bottom have been incredibly flat for the last generation. Only the top 5% have seen large gains over time. For CEOs, the gains are substantial. the multiple …

Monopsony And Salary Suppression: The Case Of Major League Soccer In The United States, John Twomey, James Monks

Economics Faculty Publications

Top tier professional soccer in the United States is operated by Major League Soccer (MLS). The MLS was established and operates under a single entity structure, such that all players negotiate and sign contracts with the league rather than with individual teams. This monopsonistic structure was designed to eliminate competition for players across teams within the league and thus allow the league to suppress player salaries. This paper investigates how effective the MLS has been in achieving this goal and finds that the MLS devotes only about 25 percent of its revenues to player salaries, compared to 50 to 60 …

Pay Secrecy And Relative Pay, Kevin F. Hallock

Economics Faculty Publications

In March 2008, the Sacramento Bee began publishing the salaries of all California state workers, including public universities. UC Berkeley professors took this information and used it to learn about pay secrecy, relative income, and how people feel and react to knowing what their co-workers earn. It turns out that there is a dramatic difference in the response to new information about wages of co-workers, depending on whether an individual has wage and salary pay above or below the median for his or her workgroup. For those who earn below the middle of their group, the new information about the …

Motivating With Efficiency Wages And Delayed Payments, Kevin F. Hallock

Economics Faculty Publications

In the delayed payment system, companies motivate workers to work hard year after year by paying them less than the value they create for the company early in the workers' tenure and more than the value they create for the company later in the workers' tenure. With efficiency wages, workers are essentially paid a wage that is higher than the next-best offer they could get. A paper by Alan Krueger found that at company-owned fast food restaurants, employee compensation is higher and the delayed payment profile is steeper than at franchised outlets. In a recent paper, Matthew Freedman and Renata …

The Relationship Between Company Size And Ceo Pay, Kevin F. Hallock

Economics Faculty Publications

The link between the size of the company and the pay of the CEO is one that is nearly impossible to make go away. One measure of the company-size-to-CEO-pay relationship is called elasticity by economists. It turns out that we can estimate the CEO compensation elasticity with respect to firm revenue, and this number is around 0.3. That is, for a 1% increase in company size, CEO pay goes up by about one-third of 1%, or for a 10% increase in company size, CEO pay goes up by about 3%. The relationship between organization size and top executive pay in …

Social Networks, Neighborhood Effects, And Credit Access: Evidence From Rural Guatemala, Bruce Wydick, Harmony Karp Hayes, Sarah Hilliker Kempf

Economics Faculty Publications

We measure the extent to which social networks determine sources of credit from a survey of 465 households in western Guatemala. We estimate correlated, contextual and endogenous effects of networks at the neighborhood, church, and village levels, finding that church networks display endogenous effects in credit access. We calculate an elasticity of social imitation (ESI) indicating if the percentage of people accessing microfinance in a church network doubles, the probability of an individual household accessing microfinance increases by 14.1 percent, a magnitude similar to our estimated ESIs for televisions and cell phones within church and neighbor networks.

Microfinance And Home Improvement: Using Retrospective Panel Data To Measure Program Effects On Fundamental Events, Craig Mcintosh, Gonzalo Villaran, Bruce Wydick

Economics Faculty Publications

Rigorously estimating the effects of development programs is notoriously difficult. In this paper we present a methodology that borrows from "event studies" commonly used in the finance literature to ascertain the impacts of corporate mergers. In our RETRAFECT methodology a retrospective panel data set is created based on “fundamental” events in the history of surveyed households, events that are discrete, unforgettable, and important to welfare. Based on the relationship between the changes in the estimated probabilities of these events and the timing of the introduction and uptake of a treatment, it is possible to ascertain if the probability of these …

The Economics Of Parenting, Self-Esteem, And Academic Performance: Theory And A Test, Rajeev Darolia, Bruce Wydick

Economics Faculty Publications

This paper develops a theory about how signals sent to a child by an altruistic parent affect a child's self-esteem, effort and long-term performance when a parent has better information about child ability than children do themselves. We carry out OLS, 2SLS, and 3SLS estimations of our model on a sample of 651 college students. Our results show some complementary actions before college, such as parental praise, foster academic achievement above what natural ability would predict. Conversely, we find some substitutionary actions before college, such as providing them cars as gifts, are associated with lower effort in college and underachievement. …

Using Real World Applications To Policy And Everyday Life To Teach Money And Banking, Dean D. Croushore

Economics Faculty Publications

Teaching a course in money and banking can be simultaneously challenging and easy. It is challenging because teaching the course well often requires a fair amount of institutional knowledge, which an instructor may not have acquired in graduate school. However, it is easy because the course can be geared to the coverage of current events, so economic data releases and the state of the economy help the instructor develop a new course every semester and produce an interesting lecture every day.

There are many different ways to teach a course on money and banking. At most schools, the only prerequisite …

Confucianism And The Legalism: A Model Of The National Strategy Of Governance In Ancient China, Haiwen Zhou

Economics Faculty Publications

The Confucian school emphasizes family value, moral persuasions, and personal relations. Under Confucianism, there is a free-rider issue in the provision of efforts. Since national officials are chosen through personal relations, they may not be the most capable. The Legalist school emphasizes the usage of incentives and formal institutions. Under the Legalism, the ruler provides strong incentives to local officials which may lead to side effects because some activities are noncontractible. The cold-blood image of the Legalism may alien citizens. By exploiting the paternalistic relationship between the ruler and the ruled under Confucianism and the strength of institution-building under the …

Public Policy, Human Instincts, And Economic Growth, Jonathan B. Wight

Economics Faculty Publications

Alfred Marshall famously insisted that economics is more like biology than physics. Societies are organic ecologies that evolve and produce organized but unplanned complexity (Hayek 1979). Although no public policy reliably produces economic growth across all ecosystems, a key element unites diverse institutions and policies that do seem to work: they all are reasonably compatible with human instinct. Institutions that build on the basic instinct for self-betterment (as in markets) have a much easier time in achieving success than institutions that oppose it (as in communism). Instincts, like gravity, are a force of nature. Adam Smith theorized, for example, …

Cost Efficiencies And Rankings Of Flagship Universities, G. Thomas Sav

Economics Faculty Publications

Problem Statement:

Each state in the U.S. touts a premier university as the flagship of its publicly funded higher education system. With decreased government budgets and increased interest in public management reforms, these institutions are being pressured to provide evidence of and set examples for ever greater improvements in operating cost efficiencies. The problem, however, is that empirical measures of their efficiencies or inefficiencies can be sensitive and, therefore, vary widely depending upon the underlying model specification.

Approach:

The study used stochastic frontier analysis to estimate university cost inefficiencies over the 2005-09 academic years. Transom and Cobb-Douglas specifications were combined …

Real-Time Forecasting, Dean D. Croushore

Economics Faculty Publications

This chapter will discuss real-time forecasting in a macroeconomic policy context. I will begin by talking about the Survey of Professional Forecasters (SPF), a survey of private-sector forecasters. Next, I will discuss research on real-time data analysis and its importance in forecasting. Finally, I will discuss real-time forecasting in the 1990s.
