Social Determinants Of Health: The Impact On Health Outcomes And Hospital Profitability, Danielle Mcpherson
Social Determinants Of Health: The Impact On Health Outcomes And Hospital Profitability, Danielle Mcpherson
Doctor of Business Administration Dissertations
Hospitals are experiencing decreasing profitability due to increasing healthcare cost. In this paper, I demonstrate that there is financial value to hospitals by addressing social determinants of health (SDOH) as this strategy improves health outcomes and yields cost savings. I estimate the impact of SDOH on the health outcomes using an IV probit regression analysis and estimated the impact of health outcomes on cost using a basic linear regression. I estimate that improving SDOH by one standard deviation will result in hospital cost savings as follows: addressing Violent Crime will decrease hospital cost between 0.16% and 0.21%, addressing Supplemental Nutrition …
The Chow Test With Time Series-Cross Section Data, James K. Binkley, Jeffrey Young
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.
Purchasing Power Parity Approach To Exchange Rate Misalignment In Nigeria, Nakorji Musa, Agboegbulem Ngozi T. I., Gaiya Blessing A., Atoi Ngozi V.
Purchasing Power Parity Approach To Exchange Rate Misalignment In Nigeria, Nakorji Musa, Agboegbulem Ngozi T. I., Gaiya Blessing A., Atoi Ngozi V.
CBN Journal of Applied Statistics (JAS)
This study examines the purchasing power parity (PPP) approach to the determination of exchange rate misalignment in Nigeria by using two variants of the PPP: the absolute PPP (aPPP) and the relative PPP (rPPP). Data on the Nigerian Naira to US Dollar (N/$), British Pound (N/£) and Chinese Yuan (N/¥) interbank exchange rates, Nigeria consumer price index and Inflation as well as the US, UK and China consumer price indices and inflation rates spanning 2008:M1 to 2018:M12 were utilized. A recently modified fractional cointegration framework was employed, taking care of smooth structural breaks and nonlinearity, while the unit root tests …
Analysing User Experience Of Mobile Banking Applications In Nigeria: A Text Mining Approach, Omotosho Babatunde S.
Analysing User Experience Of Mobile Banking Applications In Nigeria: A Text Mining Approach, Omotosho Babatunde S.
CBN Journal of Applied Statistics (JAS)
This paper analyses textual data mined from 37,460 reviews written by mobile banking application users in Nigeria over the period November 2012 – July 2020. On a scale of 1 to 5 (5 being the best), the average user rating for the twenty-two apps included in our sample is 3.5; with the apps deployed by non-interest banks having the highest average rating of 4.0 and those by commercial banks with national authorisation having the least rating of 3.4. Results from the sentiment analysis reveal that the share of positive sentiment words (17.8%) in the corpus more than double that of …
Money And Foreign Exchange Markets Dynamics In Nigeria: A Multivariate Garch Approach, Atoi Ngozi V., Nwambeke Chinedu G.
Money And Foreign Exchange Markets Dynamics In Nigeria: A Multivariate Garch Approach, Atoi Ngozi V., Nwambeke Chinedu G.
CBN Journal of Applied Statistics (JAS)
This study examines the money market and foreign exchange market dynamics in Nigeria by estimating the dynamic correlation and volatility spillovers between the Nigeria Naira/US Dollar Bureau De Change (BDC) exchange rate and interbank call rate with data from January 2007 to August 2019. The study employs a dynamic conditional correlation form of the GARCH model (DCC-GARCH) to assess the nature of correlation, while an unrestricted bivariate BEKK-GARCH (1, 1) form of the multivariate GARCH model is utilized to investigate shocks and volatility spillover of the rates. The estimated DCC-GARCH (1, 1) reveals that interest rate and exchange rate are …
Impact Of Government Expenditure On Economic Growth In Nigeria, 1970-2019, Aluthge Chandana, Jibir Adamu, Abdu Musa
Impact Of Government Expenditure On Economic Growth In Nigeria, 1970-2019, Aluthge Chandana, Jibir Adamu, Abdu Musa
CBN Journal of Applied Statistics (JAS)
This study investigates the impact of Nigerian government expenditure (disaggregated into capital and recurrent) on economic growth using time series data for the period 1970-2019. The paper employs Autoregressive Distributed Lag (ARDL) model. To ensure robustness of results, the study accounts for structural breaks in the unit root test and the co-integration analysis. The key findings of the study are that capital expenditure has positive and significant impact on economic growth both in the short run and long run while recurrent expenditure does not have significant impact on economic growth both in the short run and long run. The study …
Data Driven Value-At-Risk Forecasting Using A Svr-Garch-Kde Hybrid, Marius Lux, Wolfgang Karl Hardle, Stefan Lessmann
Data Driven Value-At-Risk Forecasting Using A Svr-Garch-Kde Hybrid, Marius Lux, Wolfgang Karl Hardle, Stefan Lessmann
Sim Kee Boon Institute for Financial Economics
Appropriate risk management is crucial to ensure the competitiveness of financial institutions and the stability of the economy. One widely used financial risk measure is value-at-risk (VaR). VaR estimates based on linear and parametric models can lead to biased results or even underestimation of risk due to time varying volatility, skewness and leptokurtosis of financial return series. The paper proposes a nonlinear and nonparametric framework to forecast VaR that is motivated by overcoming the disadvantages of parametric models with a purely data driven approach. Mean and volatility are modeled via support vector regression (SVR) where the volatility model is motivated …
Commodities Are Not Industries! A Value Chain Example, Randall W. Jackson, Patricio Aroca
Commodities Are Not Industries! A Value Chain Example, Randall W. Jackson, Patricio Aroca
Regional Research Institute Working Papers
Leontief and Stone both received Nobel Prizes in Economics for development and extension of input-output (IO) analysis, a framework that has gained little traction in mainstream U.S. economics. Although IO modeling has gained renewed focus in several problem domains, many contemporary economists eschew Stone's enhancements, resulting in inconsistent analytics, even in top economics journals. In this paper, we use an increasingly common approach to value chain analysis as one example that demonstrates such conceptual misunderstandings and by presenting properly formulated alternatives, we demonstrate the extent of the consequences of neglecting the Stone enhancements and important role of reproducing results.
Regional Household Economic Stress And Retail Sales Fluctuations, Thomas M. Fullerton Jr., Ana P. Gutierrez-Zubiate
Regional Household Economic Stress And Retail Sales Fluctuations, Thomas M. Fullerton Jr., Ana P. Gutierrez-Zubiate
Departmental Papers (E & F)
Economic stress indices are used to monitor business cycle conditions in several regions.Although the deployment of these tools is spreading, there have been relatively few efforts to empirically assess the performance of these gauges, especially at the regional level.This study takes advantage of one such index that is published monthly and has more than 15 years of historical data.Results obtained confirm an inverse relationship between household economic duress and retail sales activity, but it is not found to be statistically reliable over the long-run.Deviations from equilibrium are found to last for 142 months.More relevantly, a 1-point increase in the index …
Analyzing Competitive Balance In Professional Sport, Kevin Alwell
Analyzing Competitive Balance In Professional Sport, Kevin Alwell
Honors Scholar Theses
In this paper we review several measures to statistically analyze competitive balance and report which leagues have a wider variance of performance amongst its competitors. Each league seeks to maintain high levels of parity, making matches and overall season more unpredictable and appealing to the general audience. Here we quantify competitive advantage across major sports leagues in numbers using several statistical methods in order for leagues to optimize their revenue.
Unconditional Quantile Regression Analysis Of Uk Inbound Tourist Expenditures, Abhijit Sharma, Richard Woodward, Stefano Grillini
Unconditional Quantile Regression Analysis Of Uk Inbound Tourist Expenditures, Abhijit Sharma, Richard Woodward, Stefano Grillini
Articles
Using International Passenger Survey (2017) data, this paper employs unconditional quantile regression (UQR) to analyse the determinants of tourist expenditure amongst inbound tourists to the United Kingdom. UQR allows us to estimate heterogeneous effects at any quantile of the distribution of the dependent variable. It overcomes the econometric limitations of ordinary least squares and quantile regression based estimates typically used to investigate tourism expenditures. However, our results reveal that the effects of our explanatory variables change across the distribution of tourist expenditure. This has important implications for those tasked with devising policies to enhance the UK’s tourist flows and expenditures.
Environmental Governance For Whom? Examining The Political, Institutional, Fiscal, And Legal Determinants Of State Environmental Agency Budget Policy In The Us, Andrew R. Duggan
Environmental Governance For Whom? Examining The Political, Institutional, Fiscal, And Legal Determinants Of State Environmental Agency Budget Policy In The Us, Andrew R. Duggan
Theses and Dissertations
Budgets are a prospective tool of governance, and appropriations are a planning vehicle reflecting: bureaucracies’ values, complex interactions, collective preferences, political influences, and available resources. Research spanning 30 years finds that environmental pollution is a key determinant of environmental budgets in the US, though myriad factors, actors, and subsystems are important to consider. Due to federalism and devolution of responsibilities and authorities, environmental governance falls largely to the states. While the dynamics that shape state environmental budget policy have received scholarly interest, theoretically-driven examinations of environmental appropriations remain limited within the public budgeting and environmental policy literature.

Does Racial Discrimination Exist In The Nba?, Logan Kendall
Does Racial Discrimination Exist In The Nba?, Logan Kendall
Williams Honors College, Honors Research Projects
This paper aims to examines the affect of race on compensation for NBA players. Based on prior research, I pose the hypothesis that racial discrimination does exist in the NBA with there being a premium for white players. A second hypothesis I present based on the previous research is that the premium for white players exist for only some groups of players and for other groups there with not exist discrimination based on player race. By using career data from every player who played in the 2019-2020 NBA season and their 2019-2020 salaries, a few different models where ran. The …

Three Essays On Health Economics And Policy Evaluation, Shishir Shakya
Graduate Theses, Dissertations, and Problem Reports
This dissertation consists of three essays on the U.S. Health care policy. Each paragraph below refers to the three abstracts for the three chapters in this dissertation, respectively. I provide quantitative evidence on how much Prescription Drug Monitoring Programs (PDMPs) affects the retail opioid prescribing behaviors. Using the American Community Survey (ACS), I retrieve county-level high dimensional panel data set from 2010 to 2017. I employ three separate identification strategies: difference-in-difference, double selection post-LASSO, and spatial difference-in-difference. I compare how the retail opioid prescribing behaviors of counties, that are mandatory for prescribers to check the PDMP before prescribing controlled substances …
