A Mixture Autoregressive Model Based On Student’S T–Distribution, Mika Meitz, Daniel Preve, Pentti Saikkonen

Research Collection School Of Economics

A new mixture autoregressive model based on Student’s t–distribution is proposed. A key feature of our model is that the conditional t–distributions of the component models are based on autoregressions that have multivariate t–distributions as their (low-dimensional) stationary distributions. That autoregressions with such stationary distributions exist is not immediate. Our formulation implies that the conditional mean of each component model is a linear function of past observations and the conditional variance is also time-varying. Compared to previous mixture autoregressive models our model may therefore be useful in applications where the data exhibits rather strong conditional heteroskedasticity. Our formulation also has …

Is Democracy Good For Growth? Development At Political Transition Time Matters, Di Sima, Fali Huang

Research Collection School Of Economics

Is democracy a better political regime for economic prosperity than autocracy? This paper shows that the answer depends on the initial economic development level during the democratic transition when the foundation of institutions was laid. Democracy facilitates growth only in countries that already have adequate development at transition time. These countries are more likely to create and sustain growth-enhancing institutions than others. Without appropriate development, democracy does not improve growth; this applies to about 40% of the third-wave democratized countries. These results are based on a sample of 153 countries in 1960–2010 and robust to various specifications and endogeneity issues.

School Attendance Information Or Conditional Cash Transfer? Evidence From A Randomized Field Experiment In Rural Bangladesh, Tomoki Fujii, Christine Ho, Rohan Ray, Abu S. Shonchoy

Research Collection School Of Economics

Low school attendance remains an important challenge in resource-poor settings with cash and information constraints. We compare conditional cash transfer (CCT) treatments with framing variations (gain and loss) against attendance information treatment as interventions to address these constraints in a unified framework. Our randomized evaluation shows CCT treatments increase attendance by 11 percentage points, about half of which is attributable to attendance information. These treatments improve girls’ academic aspirations and reduce early marriage. Daily CCT set at a quarter of local child wage maximizes attendance impact. We highlight the importance of low-cost information technology to boost attendance sustainably and cost-effectively.

Retail Pharmacies And Drug Diversion During The Opioid Epidemic, Aljoscha Janssen, Xuan Zhang

Research Collection School Of Economics

This study investigates the role of retail pharmacy ownership in the opioid epidemic. Using data of prescription opioid orders, we show that compared with chain pharmacies, independent pharmacies dispense 39.1% more opioids and 60.5% more OxyContin. After an independent pharmacy becomes a chain pharmacy, opioid dispensing decreases. Using the OxyContin reformulation, which reduced non-medical demand but not the legitimate medical demand, we show that at least a third of the difference in the amount of OxyContin dispensed can be attributed to non-medical demand. We show that differences in competitive pressure and whether pharmacists own the pharmacy drive our estimates.

Volatility Puzzle: Long Memory Or Antipersistency, Shuping Shi, Jun Yu

Research Collection School Of Economics

The log realized volatility (RV) is often modeled as an autoregressive fractionally integrated moving average model ARFIMA(1, d, 0). Two conflicting empirical results have been found in the literature. One stream shows that log RV has a long memory (i.e., the fractional parameter d > 0). The other stream suggests that the autoregressive coefficient α is near unity with antipersistent errors (i.e., d

How Public Health Expenditure Affect Health Outcomes In Cameroon, Gilbert Njinju Ayimaleh

Walden Dissertations and Doctoral Studies

Most African governments, and Cameroon in particular, have identified the reduction of infant mortality and life expectancy in Africa as a critical priority. The United Nations Millennium Development Goals set a target objective of reducing infant mortality by 60% from 1990 to 2015 in less-developed countries. Good health contributes significantly to the attainment of sustainable development and health outcomes. Despite Cameroon’s progress in achieving health-related Millennium Development Goals regarding reducing infant mortality and increasing life expectancy, the country is still worse in respect to health outcomes compared to other Sub-Saharan Countries like Nigeria and Ghana thus more need to be …

Essays In Applied Microeconomics, Joshua C. Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first chapter examines the role that same-sex marriage legalization had on the number of adoptions of children from foster care in the United States. We do so by employing a synthetic difference-in-differences estimator which leverages both the differential timing of these laws across states and the subsequent wave of state-level legal protections which give foster-care agencies the right to deny service to same-sex couples based on religiously-held beliefs. Using highly detailed, county-level data of nearly 20 million children in the foster care system from 1995-2020, our findings reveal that same-sex marriage legalization led to a 3.8%-5.9% increase in the …

Synergies Between Residents: Evaluating Support And Concerns Of Recreation And Tourism Economic Development Within The Monongahela National Forest Region, Morgan R. Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tourism has continually been presented as a growing economic sector around the world. Having become an area of increased interest for diversifying rural economies, tourism is an attractive alternative to the declining traditional economic engines of rural communities like agriculture, forestry, and mining. Rural destinations have become increasingly attractive to outside visitors who seek to pursue activities embedded within the local culture and distinctive attractive assets available in rural regions. The USDA has recognized the increasing importance of recreation and tourism economies as an emerging or priority area of national need and an effective means for rural development. Even with …

Integrating Feminist Approaches In Counseling Work With Adult Women, Kristen M. Toole

Adultspan Journal

The scope of ‘women’s issues’ in counseling is an ever-evolving landscape. Recent events such as the reversal of Roe v. Wade and the disproportionate impact of COVID-19 on women serve as powerful reminders of the necessity of this focus while underscoring a deep-rooted history of oppressive patriarchal structures. Therefore, counselors must remain informed of the unique considerations surrounding adult women in counseling and acquire proficiency in versatile techniques to meet this population’s nuanced needs. This article examines the complexity of contemporary womanhood and explores the fundamentals of Feminist Counseling Theory (FCT), a holistic, multiculturally conscious, social justice theory in counseling. …

Beyond The Labor Exemption: Labor's Antimonopoly Vision And The Fight For Greater Democracy, Kate Andrias

Faculty Scholarship

Although the labor movement and the antimonopoly movement both oppose concentrated economic power and bemoan rising inequality, their projects are frequently viewed as divergent, if not incompatible. According to the conventional account, the labor movement has historically lacked an affirmative antimonopoly agenda, instead focusing its demands on achieving a labor exemption to the antitrust laws. This chapter shows, however, that left-leaning industrial unions from the late nineteenth century through the mid-twentieth century repeatedly and insistently used the language of antimonopoly to argue that private concentrations of economic power posed a grave threat to workers and to democracy. But labor’s vision …

Relationship Between Perceived Language Proficiency And Economic Life Satisfaction For Migrants, John Ndunduma

Walden Dissertations and Doctoral Studies

The United States needs migrant workers to fill the labor market gap because baby boomers are retiring from the US workforce in large numbers beginning in 2020. Approximately 2.1 million migrants came from Africa to fill the U.S. labor shortage. Many of these African migrants faced challenges with English language proficiency. There are benefits to the United States involved with increasing the economic wellbeing of migrants, such as reducing remigration, increasing the high-skilled labor force, and increasing cultural diversity. This study used Maslow’s motivational theory to test significant relationships between perceptions of English language proficiency (PELP) and economic life satisfaction …

Part 6: Should Taxpayers Subsidize Private Facilities In Hampton Roads? Glitz Vs. Reality, Dragas Center For Economic Analysis And Policy, Old Dominion University

State of the Region Reports: Hampton Roads

Hampton Roads can learn from the experience of other cities and states. If there is a strong business case for a sports stadium, sports park, or entertainment venue, then investors should be able to tap into financial markets. In this chapter, we examine the arguments surrounding public investments in highly visible facilities. We pose questions that should be asked when considering such investments and explore the potential opportunity costs of these projects. We offer a cautionary tale that such projects are sold as transformative but often fail to generate the promised benefits, not only for taxpayers but also for the …

Pollution Emissions And Economic Growth In Asia Through The Lens Of The Environmental Kuznets Curve, Brian Jason H. Ponce, Yolanda T. Garcia, Gideon P. Carnaje, Agham C. Cuevas

Journal of Economics, Management and Agricultural Development

The nonlinear relationship of pollution emissions with economic growth alongside energy consumption variables was examined to test the Environmental Kuznets Curve (EKC) hypothesis using a panel sample comprising 34 Asian economies from 2001 to 2013. Panel Autoregressive Distributed Lag models in the forms of Pooled Mean Group and Mean Group models were estimated and tested against one another using the Hausman test. For robustness checks, the same econometric techniques were applied to disaggregated panel groups based on income classifications. The study reveals that, while the EKC hypothesis holds in Asia, the findings were not robust across the disaggregated panel groups. …

Economic Implications Of International Energy Trade : A Comparative Analysis Across Developed, Developing, And Least Developed Nations, Mmaduabuchi Chigozie Emeghebo, Bintou K.B. Janneh, Semeria Youlo Maurice

World Maritime University Dissertations

Energy trade and consumption constitute vital components of international trade, a significance that has been amplified by escalating global industrialization and globalization. Nonetheless, the patterns of demand, trade, and utilization of energy differ markedly across various categories of economies, as delineated by the United Nations into Developed, Developing, and Least Developed Nations.

This study endeavors to elucidate the influence of international energy trade and consumption on the economic development trajectories of these three distinct categories of nations. Employing linear panel regression methodologies on panel data sets spanning the period from 1995 to 2021 for each category, the analysis reveals that …

Human Development And Macroeconomic Shocks In Nigeria: An Empirical Investigation, Risikat O.S. Dauda, Onyebuchi Iwegbu

Journal of Social, Behavioral, and Health Sciences

This paper explores how human development responds to selected macroeconomic shocks in Nigeria. The study employed the Sen’s capabilities approach as the analytical approach and posited that the level of education, health status, quality of investment, technology, and government fiscal and monetary policies are plausible determinants of human development. We used the Structural Vector Autoregression (SVAR) to estimate the responses of such selected shocks, which are inflation, interest rate, government capital expenditure, exchange rate, current account balance, and savings shocks. The Forecast Error Variance Decomposition (FEVD) and the Impulse Response (IR) showed that a fiscal policy shock is the major …

Growth And Distribution: Revisting Solow’S Growth Models From The Perspective Of The Marxian Circuit Of Capital, Hee-Young Shin

Economics Faculty Publications

The aggregate production function used in Solow’s growth models assumes the constancy in relative income distribution between owners of capital and labor input. The paper discusses the validity of this fundamental assumption and attempts to identify the necessary condition for the balanced and equi-proportional growth of relative incomes from the perspective of the Marxian circuit of capital model. The analysis in this paper shows that the constancy and proportionality in the growth of two social class incomes are not consistent with real-world patterns of the capital accumulation process, in which the decision over capitalization of realized surplus value that determines …

“Model Minorities” In The Classroom? Positive Evaluation Bias Towards Asian Students And Its Consequences, Ying Shi, Maria Zhu

Center for Policy Research

The fast-growing demographic group of Asian Americans is often perceived as a “model minority.” This paper establishes empirical evidence of this stereotype in the context of education and then analyzes its consequences. We show that teachers rate Asian students’ academic skills more favorably than observationally similar White students in the same class, even after accounting for test performance and behavior. This contrasts with teachers’ lower likelihood of favoring Black and Hispanic students. Notably, teachers respond to the presence of any Asian student in the classroom by exacerbating Black-White and Hispanic-White assessment gaps. This suggests that the “model minority” stereotype can …

Robust Dynamic Space-Time Panel Data Models Using Ε- Contamination: An Application To Crop Yields And Climate Change, Badi H. Baltagi, Georges Bresson, Anoop Chaturvedi, Guy Lacroix

Center for Policy Research

This paper extends the Baltagi et al. (2018, 2021) static and dynamic ε-contamination papers to dynamic space-time models. We investigate the robustness of Bayesian panel data models to possible misspecification of the prior distribution. The proposed robust Bayesian approach de-parts from the standard Bayesian framework in two ways. First, we consider the ε-contamination class of prior distributions for the model parameters as well as for the individual effects. Second, both the base elicited priors and the ε-contamination priors use Zellner (1986)’s g-priors for the variance-covariance matrices. We propose a general “toolbox” for a wide range of specifications which includes the …

Lessons Learned: Patrick Honohan, Maryann Haggerty

Journal of Financial Crises

Patrick Honohan, an economist, was governor of the Central Bank of Ireland and a member of the Governing Council of the European Central Bank (ECB) from September 2009 until November 2015. Early in his tenure, he led a team that investigated the causes of the Irish banking crisis that broke out in 2008 during the Global Financial Crisis. Resolving the problems of bank failure and over-indebtedness that emerged in that crisis dominated his term of office. In late 2010, Ireland had to request financial assistance from the “troika” of the International Monetary Fund (IMF), the European Commission, and the European …

Malaysia: Reserve Requirements, Afc, Bailey Decker

Journal of Financial Crises

Bank Negara Malaysia (BNM) unpegged the ringgit in July 1997, days after Thailand floated the baht. Ringgit depreciation and adverse investor sentiment worsened, contributing to a domestic liquidity shortage and capital flight. Malaysia experienced market instability in the early months of 1998, particularly pressure on its exchange rate, foreign currency reserves, and interest rates. At the same time, disruptions in the domestic money market and loan intermediation process caused an increase in lending rates, which resulted in debt servicing problems and weakened financial stability. To facilitate lending and productive economic activity, BNM twice lowered the statutory reserve requirement (SRR) at …

Jamaica: Reserve Requirements, Gfc, Corey N. Runkel

Journal of Financial Crises

In October 2008, the Global Financial Crisis (GFC) and liquidity shortages rocked American and European markets, causing investors to exit liquid Jamaican-dollar assets. The Bank of Jamaica (BOJ) feared a “disorderly depreciation” in the Jamaican-dollar (JMD) exchange rate to the US dollar (BOJ 2009, 44). In response, the BOJ raised required reserve ratios for cash and other liquid assets, the first increases since 2002. The BOJ raised reserve ratios three times—in December 2008, January 2009, and February 2009—because the central bank could not change its requirements by more than 200 basis points per month. The BOJ raised the requirement for …

India: Reserve Requirements, Gfc, Sharon Nunn, Carey K. Mott

Journal of Financial Crises

As international funding sources dried up during the Global Financial Crisis of 2007–2009 (GFC), businesses in India sought funds from domestic financial institutions, straining banks and lifting short-term lending rates. The liquidity pressure, coupled with sharp asset price corrections and rupee depreciation, restricted credit expansion in India. The Reserve Bank of India (RBI) responded with a suite of liquidity measures, including cuts to its two reserve requirement ratios, the cash reserve ratio (CRR) and the statutory liquidity ratio (SLR). The RBI cut the CRR over the course of four months from October 2008 to January 2009, lowering the ratio from …

Czech Republic: Reserve Requirements, 1997, Benjamin Hoffner

Journal of Financial Crises

In the first quarter of 1997, fiscal and current account deficits in the Czech Republic put pressure on the koruna’s pegged exchange rate as capital flowed out of the domestic economy. Although the Czech National Bank (CNB) committed to tight monetary policy to protect the peg, on April 11, the CNB announced a lowering of the minimum reserve requirement (RR) ratio from 11.5% to 9.5%, effective May 8. The RR ratio (RRR) reduction (RRR) reflected a compromise with the government, which had petitioned the central bank to ease monetary policy. To improve the balance of payments, the government also implemented …

Ecuador: Blanket Guarantee, 1998, Bailey Decker

Journal of Financial Crises

After a series of exogenous shocks hit the Ecuadorian economy in 1997–1998, foreign creditors reassessed their emerging-market risk and reduced external credit lines to Ecuador, thus draining liquidity. The closure of a small bank called Solbanco in April 1998 triggered deposit runs at other banks. Banks sought assistance from the Central Bank of Ecuador (Banco Central del Ecuador, or BCE). By the end of September 1998, the BCE had issued emergency loans to 11 financial institutions, totaling nearly 30% of the money base. The crisis accelerated in August 1998 when Banco de Prestamos, the sixth-largest bank, was closed; the existing …
