When Vertical Is Horizontal: How Vertical Mergers Lead To Increases In “Effective Concentration”, Serge Moresi, Steven C. Salop

Georgetown Law Faculty Publications and Other Works

This article explains the inherent loss of an indirect competitor and reduction in competition when a vertical merger raises input foreclosure concerns. We then calculate a measure of the effective increase in the HHI measure of concentration for the downstream market, and we refer to this “proxy” measure as the “dHHI.” We derive the dHHI measure by comparing the pricing incentives and associated upward pricing pressure (“UPP”) involved in two alternative types of acquisitions: (i) vertical mergers that raise unilateral input foreclosure concerns (and the associated vertical GUPPI measures), and (ii) horizontal acquisitions of partial ownership interests among …

The Conservatism Principle And Asymmetric Preferences Over Reporting Errors, Jivas Chakravarthy, Timothy W. Shields

ESI Working Papers

At present, accounting conservatism is generally viewed from a measurement or reporting perspective. In contrast, we consider whether it relates to a moral rule of conduct. Conservatism has been described as deriving from a preference for reporting errors to be in the direction of understatement rather than overstatement. We experimentally pair Reporters who provide information with Users who rely on the information. We posit that under misaligned incentives that motivate aggressive reporting, Users view an aggressive report as reflecting Reporters’ exploitative intent and expect that a social norm prohibiting aggressive reporting applies. We predict that Users use noisy reporting errors …

The Evolutionary Global Vision Of Chinese Political Philosophy; China's Socio-Economic Transformation In The 21st Century, Meryem Gurel

Master's Projects and Capstones

Evolving relations of East Asia due to trade liberalization raised the search for financial stability for institutional development. It also increased the importance of China integrating the global economy into renewing its political philosophy in the new century. This capstone project aims to examine why China has transformed its socio-economic structure by generating outward investments and how it has affected international political relations in terms of the role of the economic institution Asian Infrastructure Investment Bank (AIIB). Quantitative methodology aims to examine the impact of China’s export trade on income distribution and economic growth through linear regression analysis for the …

Credit Cards, Credit Utilization, And Consumption, Scott Fulford, Scott Schuh

Economics Faculty Working Papers Series

Credit bureau data show remarkably stable consumer utilization of unsecured debt over the business cycle, life cycle, and individually quarter-to-quarter, despite massive variation in available credit. To explain these new findings, we propose a life-cycle consumption model with heterogeneous preferences, endogenous payment choice, and the option to revolve debt for consumption smoothing. Using diary data to identify payment use, the estimated model matches consumption and credit use at every frequency and suggests that around half the population has an endogenously high marginal propensity to consume. The results suggest understanding credit availability and heterogeneous use may lead to richer counter-cyclical policies.

A Capital Asset Pricing Model With Idiosyncratic Risk And The Sources Of The Beta Anomaly, Mark Schneider, Manuel A. Nunez

ESI Working Papers

We introduce a generalization of the classical capital asset pricing model in which market uncertainty, market sentiment, and forms of idiosyncratic volatility and idiosyncratic skewness are priced in equilibrium. We derive two versions of the model, one based on a representative agent who cares about three criteria (risk, robustness, and expected returns), and the other with a microfoundation based on three types of investors (speculators, hedgers, and arbitrageurs). We apply the resulting capital asset pricing model with idiosyncratic risk (IR-CAPM) to provide a new theoretical account of the beta anomaly, one of the most fundamental and widely studied empirical limitations …

When The Great Equalizer Shuts Down: Schools, Peers, And Parents In Pandemic Time, Francesco Agostinelli, Matthias Doepke, Giuseppe Sorrenti, Fabrizio Zilibotti

Cowles Foundation Discussion Papers

What are the effects of school closures during the Covid-19 pandemic on children’s education? Online education is an imperfect substitute for in-person learning, particularly for children from low-income families. Peer effects also change: schools allow children from different socio-economic backgrounds to mix together, and this effect is lost when schools are closed. Another factor is the response of parents, some of whom compensate for the changed environment through their own efforts, while others are unable to do so. We examine the interaction of these factors with the aid of a structural model of skill formation. We find that school closures …

Beyond Mechanical Markets: Asset Price Swings, Risk, And The Role Of The State (Book Review), Adrian Ravier

Journal of New Finance

In its opening section, Frydman and Goldberg’s book lays out important methodological contributions questioning the hypothesis of rational expectations, constructed on the basis of the writings of Knight, Keynes and Hayek. But in the second part, it does not propose a convincing model that would help avoid the formation of new financial bubbles. While accepting to some extent that the government entity has no greater knowledge than economic agents, it ignores the perverse public-sector incentives that James M. Buchanan and the School of Public Choice have explored in recent decades. Furthermore, although the repeated reference to Hayek is encouraging, the …

The Structure Of Production And Endogenous And Exogenous Liquidity Of Financial Intermediaries, Daniel Fernández

Journal of New Finance

Banks directly manage their own liquidity. Banks also indirectly manage the liquidity of the entire economic system. In this article we discuss the relationship between endogenous and exogenous bank liquidity, and their corresponding relationship to the structure of production. We explore these liquidity relationships in the context of both a decentralized and centralized system of free banking, comparing both with the monopoly regime of central banks, “convertible and inconvertible liabilities. We analyze the incentives that engender a liquid “system in the context of free banking as well as the perversion of those same incentives in the context of central banking, …

Working Paper No. 45, An Intellectual History Of Josiah Warren, Jaye Balentine

Working Papers in Economics

This inquiry seeks to establish that Josiah Warren (1798-1874) developed a synthesis of anti-capitalist economics and radical individualism which became a unique, yet highly practical strand of anarchism in the United States. This inquiry relies heavily upon Crispin Sartwell’s The Practical Anarchist: Writings of Josiah Warren (2011) for insight into Warren’s contributions. Warren registers as distinct because of his relative isolation from other anarchist thinkers, existing largely as a lone practitioner operating in the western territories of the United States during middle-part of the 19th century. This inquiry considers Warren’s philosophical views as well as his practical program—namely his doctrines …

Working Paper No. 46, Foundations For Feminist Legal Theory, Taylor Feltham

Working Papers in Economics

This inquiry seeks to establish the foundations for Feminist Legal Theory through considering its three important dimensions. These dimensions are: a) a distinct and unique historical background; b) an ongoing legacy of occupational segregation; and c) a persistence of gender inequality. This inquiry relies heavily upon Feminist Legal Theory: A Primer (2016) authored by Nancy Levit, et al. Since the emergence of the area of inquiry known as “critical race feminism,” feminist legal theory has been moving away from the principle of formal equality and towards intersectional equity. Feminist legal theorists like Angela Harris (1990), in her work Race and …

Explaining The Nonlinear Response Of Stock Markets To Oil Price Shocks, Diego Escobari, Shahil Sharma

School of Economics and Finance Faculty Publications

This paper is set to reconcile the existent conflicting empirical evidence on the effect of oil prices on stock prices. We estimate various nonlinear models where the response changes according to a first-order Markov switching process. More importantly, we model the transition probabilities between the high- and low-response regimes to depend on state variables to allow us to explain the forces behind the asymmetry in the response. The results show statistically significant asymmetries that can be explained by economic recessions and to a lower extent depend on the magnitude of the oil price shift and on whether the shift is …

Mum’S The Word: Are Mothers Choosing To Give Up Their Careers Or Being Booted Out Of The Labor Force?, Harini Chakrapani

Capstones

Since the pandemic began, mothers have been leaving the labor force in droves. Mum’s the Word: Are mothers choosing to give up their careers or being booted out of the labor force examines the reasons that are forcing mothers to quit their jobs, the cost of mothers’ not participating in the labor force and what steps corporations and the government can take to support mothers’ return to the labor force. https://www.hcpani.com/post/mum-s-the-word-are-mothers-choosing-to-give-up-their-careers-or-being-booted-out-of-the-labor-force

Financial Literacy For Latino Immigrants: A Guidebook For Esl Teachers, Anna Braden

Master's Projects and Capstones

Latino immigrants face many financial challenges in the United States. Language barriers exclude them from jobs as well as financial and consumer markets. Lack of familiarity with the U.S. financial system or bad experiences with financial systems in their home countries can create mistrust and lead to Latino immigrants being unbanked or underbanked. Consumer vulnerabilities may also be exploited as immigrants turn to nonbank financial services such as predatory lenders (check cashers, payday lenders, etc.). Lack of access to jobs and marketplaces results in lower income and less wealth accumulation. Over time this results in wealth inequality between Latino immigrants …

Income In The Off-Season: Household Adaptation To Yearly Work Interruptions, John Coglianese, Brendan M. Price

Upjohn Institute Working Papers

Joblessness is highly seasonal. To analyze how households adapt to seasonal joblessness, we introduce a measure of seasonal work interruptions premised on the idea that a seasonal worker will tend to exit employment around the same time each year. We show that an excess share of prime-age U.S. workers experience recurrent separations spaced exactly 12 months apart. These separations coincide with aggregate seasonal downturns and are concentrated in seasonally volatile industries. Examining workers most prone to seasonal work interruptions, we find that these workers incur large earnings losses during the off-season. Lost earnings are 1) driven mainly by repeated separations …

The Chow Test With Time Series-Cross Section Data, James K. Binkley, Jeffrey Young

Faculty & Staff Research and Creative Activity

The Chow test is a standard method to test for differences in regression response across groups. In some cases, the groups being tested are composed of a time series of cross sections. If the individual units within the groups have systematic differences, the Chow test is compromised: individual and group effects become confounded. This can cause rejections in the absence of the group effect of interest. We illustrate the problem with Monte Carlo analyses, and propose an alternative bootstrap-like testing procedure that helps eliminate excessive Type I errors.

Causality Analysis Of Disaggregated Fdi Inflows On Sectorial Growth In Oecd Area, Lawrence Ogbeifun, Olatunji Abdul Shobande

Faculty and Student Publications

This article revisits the link between disaggregated Foreign Direct Investment (FDI) inflows and sectorial growth using the panel dataset of 25 Organisation for Economic Co-operation and Development (OECD) countries for the period 1990 to 2017. It adopted the panel fixed effect and Feasible Generalized Least Squares Approach in its analysis. The findings show that disaggregated FDI inflows have the potential to improve growth in the OECD area with adverse effects on domestic investment and inflationary pressure. Additionally, the results further indicate that disaggregated FDI inflows have a positive and significant relationship on the service and manufacturing sector but with no …

The Effect Of Robo-Advisor On Investors' Trading Behavior, Shaowei Shen

Fordham Dissertations and Theses

Robo-advisors have surged in popularity in recent years and have been attracting more and more attention from both academia and industry. In this paper, we examine the factors that attribute to investors’ decision to adopt Robo-advisor and test how Robo-advisor affects investors’ trading behavior by using a unique account-level dataset from a major China’s financial institution.

We first compare the characteristics of users and non-users of Robo-advisor. We show that investors with more diversified portfolios and less assets under management, and female investors are more likely to invest in …

Point Optimal Testing With Roots That Are Functionally Local To Unity, Anna Bykhovskaya, Peter C. B. Phillips

Research Collection School Of Economics

Limit theory for regressions involving local to unit roots (LURs) is now used extensively in time series econometric work, establishing power properties for unit root and cointegration tests, assisting the construction of uniform confidence intervals for autoregressive coefficients, and enabling the development of methods robust to departures from unit roots. The present paper shows how to generalize LUR asymptotics to cases where the localized departure from unity is a time varying function rather than a constant. Such a functional local unit root (FLUR) model has much greater generality and encompasses many cases of additional interest that appear in practical work, …

Decomposing Duration Dependence: Skill Depreciation Vs. Statistical Discrimination, Ismail Baydur, Jianhuan Xu

Research Collection School Of Economics

This paper develops a random matching model with unobserved worker heterogeneity and learning about worker types from unemployment duration. The model features negative duration dependence that stems from unobserved heterogeneity as well as statistical discrimination and skill depreciation. We estimate our model using micro-level data from Current Population Survey (CPS) and we decompose the contribution of each channel to job finding rates by duration. We find that shutting down statistical discrimination substantially increases the job finding rates of the long-term unemployed while skill depreciation mainly affects the medium-term unemployed.

Three Essays On Health Economics, Jihye Kim

Legacy Theses & Dissertations (2009 - 2024)

This thesis focuses on various factors affecting health of American adults and the elderly based on the Health and Retirement Study (HRS). In chapter 1, I examine the role of educational and racial differences in life expectancy (LE) and health-adjusted life expectancy (HALE) for Americans at ages 45-64 using Health and Retirement Study (HRS) during 2000-2016. I compute severity-weighted prevalence of diseases with comorbidity adjustments based on the Global Burden of Disease (2015), and map onto the information on 17 doctor-diagnosed diseases and four self-rated disabling health conditions from HRS. This approach allows us to evaluate the importance of major …

The Drug Overdose Epidemic Seen Through Different Lenses, Barbara Blake Gonzalez, Richard Cebula, James V. Koch

Economics Faculty Publications

The age-adjusted death rate from drug overdoses in the United States per 100,000 individuals rose from 6.8 in 2010 to 17.1 in 2018. The most common explanation offered is the deaths of despair hypothesis. We identify additional factors that have contributed to the rise in drug overdose deaths in cities and counties. Methods: We utilize a period fixed effects model with a multi-variate panel data set for 94 independent cities and counties in Virginia for the period 2008 through 2017. Results: The drug overdose mortality rate is: (a) an increasing function (prob.

He, She, We: Gender Impacts In Teamwork, Arlene J. Nicholas

Faculty and Staff - Articles & Papers

It is well known that organizational teams are highly valued in work settings (Marquis, 2019). Some research has shown gender differences such as "team collaboration is greatly improved by the presence of women in the group" (Baer & Woolley, 2011). Other studies support mixed gender teams as advantageous (Sachiko & Takeda, 2014). This paper will review the perceptions of gender contributions in teams from the literature and report on a study of current business students in a liberal arts university. Some comparisons are made to the author's 2017 survey on gender effects in team projects in the same school.

Technical Efficiency Of Public Middle Schools In New York City, William C. Horrace, Michah W. Rothbart, Yi Yang

Center for Policy Research

Using panel data and a “true” fixed effect stochastic frontier model, we estimate persistent and transient technical inefficiency in mathematics (Math) and English Language Arts (ELA) test score gains in NYC public middle schools from 2014 to 2016. We compare several measures of transient technical inefficiency and show that around 58% of NYC middle schools are efficient in Math gains, while 16% are efficient in ELA gains. Multivariate inference techniques are used to determine subsets of efficient schools, providing actionable decision rules to help policymakers target resources and incentives.

The Role Of Agriculture In The Economic Diversification Of The Nigerian Economy: (1980 – 2016), Adamu Hassan Muhammad, Tahir Hussaini Mairiga, Iliya Ayuba Thompson, Usman Ismaeel Bello

Bullion

This study empirically examines the role of agriculture in the diversification of the Nigerian economy, using time series data from 1980–2016. Estimation results using Cointegration and Vector Error Correction Technique indicate that agricultural output has a positive relationship and significant impact with non-oil exports (NOE) and that non-oil revenue has a positive relationship with non-oil exports (NOE). It was recommended that, government should endeavor to increase agricultural productivity by improving its expenditure on the sector so as to enhance the growth of the economy. Government should also increase its non-oil revenue and revive the sector through sufficient budgetary allocation and …

Impact Of Monetary Policy On Inflation Rate In Nigeria: Vector Autoregressive Analysis, Eggon Ahmed Henry, Ajidani Moses Sabo

Bullion

The Nigerian monetary authorities have implemented several monetary management policies with the aim of achieving price stability and economic growth in the country, but without success. This study was conducted to examine the impact of monetary policy management on inflation in Nigeria during the 1985- 2019. Autoregressive distributed lag analysis was employed on time series data covering the period. It was found that while monetary policy rate and foreign exchange rate impacted negatively on inflation; broad money supply impact positively on it. Therefore, the study recommended that monetary authorities should fix the exchange rate at where the value of Naira …

The Political Economy Of Small Medium Enterprise Development: Characteristics, Productive Value, And Market Constraints In Industrial Manufacturing, Christine Ngo, Miao Chi

Faculty Journal Articles

This paper highlights the importance of small and medium-sized enterprise (SME) development and introduces the theoretical concept of productive value for qualitative analysis of firms. Vietnam’s industrial development experience is used as a case study. Although the Vietnamese government has channelled rents and business opportunities towards the state sector, the domestic private sector has been crucial to the country’s industrial development. Given this context, this study analyses how Vietnamese SMEs in the private sector generate productive value and overcome market failures that constrain their growth. Research findings demonstrate that most local SMEs in the industrial sectors rely on low pricing …
