Network Competition And Team Chemistry In The Nba, William C. Horrace, Hyunseok Jung, Shane Sanders
Network Competition And Team Chemistry In The Nba, William C. Horrace, Hyunseok Jung, Shane Sanders
Center for Policy Research
We consider a heterogeneous social interaction model where agents interact with peers within their own network but also interact with agents across other (non-peer) networks. To address potential endogeneity in the networks, we assume that each network has a central planner who makes strategic network decisions based on observable and unobservable characteristics of the peers in her charge. The model forms a simultaneous equation system that can be estimated by Quasi-Maximum Likelihood. We apply a restricted version of our model to data on National Basketball Association games, where agents are players, networks are individual teams organized by coaches, and competition …
Model And Analysis Of Labor Supply For Ride-Sharing Platforms In The Presence Of Sample Self-Selection And Endogeneity, Hao Sun, Hai Wang, Zhixi Wan
Model And Analysis Of Labor Supply For Ride-Sharing Platforms In The Presence Of Sample Self-Selection And Endogeneity, Hao Sun, Hai Wang, Zhixi Wan
Research Collection School Of Computing and Information Systems
With the popularization of ride-sharing services, drivers working as freelancers on ride-sharing platforms can design their schedules flexibly. They make daily decisions regard- ing whether to participate in work, and if so, how many hours to work. Factors such as hourly income rate affect both the participation decision and working-hour decision, and evaluation of the impacts of hourly income rate on labor supply becomes important. In this paper, we propose an econometric framework with closed-form measures to estimate both the participation elasticity (i.e., extensive margin elasticity) and working-hour elasticity (i.e., intensive margin elasticity) of labor supply. We model the sample …
Structural Changes In Heterogeneous Panels With Endogenous Regressors, Badi Baltagi, Qu Feng, Chihwa Kao
Structural Changes In Heterogeneous Panels With Endogenous Regressors, Badi Baltagi, Qu Feng, Chihwa Kao
Center for Policy Research
This paper extends Pesaran (2006) common correlated e¤ects (CCE) by allowing for endogenous regressors in large heterogeneous panels with unknown common structural changes in slopes and error factor structure. Since endogenous regressors and structural breaks are often encountered in empirical studies with large panels, this extension makes the Pesaran’s (2006) CCE approach empirically more appealing. In addition to allowing for slope heterogeneity and cross-sectional dependence, we find that Pesaran’s CCE approach is also valid when dealing with unobservable factors in the presence of endogenous regressors and structural changes in slopes and error factor loadings. This is supported by Monte Carlo …
Does Medicaid Increase Emergency Room Use: Evidence From Oregon Health Program?, Md Fourkan
Does Medicaid Increase Emergency Room Use: Evidence From Oregon Health Program?, Md Fourkan
Electronic Theses and Dissertations
This thesis paper strives to identify the relationship between Medicaid expansion and Emergency Department use. I use a Monte Carlo simulation for demonstrating the endogeneity problem and a copula model using the Oregon Health Program (OHP) data to show the previous literature has exaggerated the causal relation between Medicaid expansion and Emergency Department use. This paper can be divided into two parts. First, it tries to focus on the under-identification of multiple endogenous variables problem in typical econometrics papers, where researchers correct for a single endogenous variable but intentionally or unintentionally ignore the endogeneity of one or more other independent …
How Endogeneity Matters In Framing Legalization: A Case Study Of Urban Self Help Groups In Ethiopia, Bisrat Kabeta
How Endogeneity Matters In Framing Legalization: A Case Study Of Urban Self Help Groups In Ethiopia, Bisrat Kabeta
Sustainability and Social Justice
The future of an estimated 20,000 Self Help Groups (SHGs) in Ethiopia is uncertain because they lack legal status and, therefore, are unable to access funds and service for their members. The Government of Ethiopia (GoE) does not recognize the SHGs as unique development groups, but only offers to register them as Micro and Small Enterprises (MSEs) or cooperative societies, which are solely economic entities that serve more narrow functions than SHGs do. There has not been any coherent explanation for why the SHGs need a formal status, but should not register as anything but SHGs. From May to August …
The Supplemental Nutrition Assistance Program And Childcare, Kyle Kopplin
The Supplemental Nutrition Assistance Program And Childcare, Kyle Kopplin
Electronic Theses and Dissertations
This paper attempts to analyze the effects of subsidized food dollars on the amount of daily childcare in households. More specifically, households in the low income category are of interest because they are the most likely to receive food subsidies. There has been a political debate recently in the United States which argues over the appropriate level of subsidies, if any. More importantly, food insecurity is an issue in the world; many do not know where will the next meal come from. This paper provides statistical evidence that food subsidies in the form of the Supplemental Nutrition Assistance Program (SNAP) …
Do Tax Havens Really Flourish? Accounting For Endogeneity In Growth Regressions, Luisa Blanco, Cynthia Rogers
Do Tax Havens Really Flourish? Accounting For Endogeneity In Growth Regressions, Luisa Blanco, Cynthia Rogers
School of Public Policy Working Papers
That tax haven policies contribute to favorable economic growth in tax haven countries is commonly accepted. There is, however, minimal empirical evidence to substantiate this assertion and empirical investigations are subject to endogeneity bias. Using a sample of 155 countries from 1982 to 2003, we find that the standard tax haven variable is endogenous to the error term in a typical growth regression. We offer land area measures as valid instruments for tax haven status. Results based on two-stage least squares estimation with heteroskedastic standard errors and controls for initial conditions provide support for the claim that tax havens “flourish” …
