A Bayesian analysis of binary misclassification 2017 1155 We consider Bayesian inference about the mean of a binary variable that is subject to misclassification error. If the error probabilities are not known, or cannot be estimated, the parameter is only partially identified. For several reasonable and in...
A Bayesian approach to account for misclassification in prevalence and trend estimation 2022 448 In this paper, we present a Bayesian approach to estimate the mean of a binary variable and changes in the mean over time, when the variable is subject to misclassification error. These parameters are partially identified, and we derive identified se...
Bayesian Inference in a Sample Selection Model 2011 5663 This paper develops methods of Bayesian inference in a sample selection model. The main feature of this model is that the outcome variable is only partially observed. We first present a Gibbs sampling algorithm for a model in which the selection and ...
Bayesian moment-based inference in a regression model with misclassification error 2017 1004 We present a Bayesian analysis of a regression model with a binary covariate that may have classification (measurement) error. Prior research demonstrates that the regression coefficient is only partially identified. We take a Bayesian approach which...
Binary Misclassification and Identification in Regression Models 2012 2028 We study a regression model with a binary explanatory variable that is subject to misclassification errors. The regression coefficient is then only partially identified. We derive several results that relate different assumptions about the misclassif...
Commentary on Reuter et al. - Data triangulation for substance abuse research 2021 109 Reuter et al. [1] highlight the limitations of using a general population survey (GPS) to determine the prevalence of frequent heroin use. Data from such surveys are likely to suffer from item non-response and under-reporting. In addition, frequent h...
Community Health Center Efficiency: The Role of Grant Revenues in Health Center Efficiency 2014 1924 Objective: To test the relationship between external environments, organizational characteristics, and technical efficiency in federally qualified health centers (FQHCs). We tested the relationship between grant revenue and technical efficiency in FQ...
The Economic Impact of Smoke-Free Laws on Restaurants and Bars in 9 States 2013 1839 Introduction: Smoke-free air laws in restaurants and bars protect patrons and workers from involuntary exposure to secondhand smoke, but owners often express concern that such laws will harm their businesses. The primary objective of this study was t...
Emergency Department and Inpatient Hospital Use by Medicare Beneficiaries in Patient-Centered Medical Homes 2015 224 Study objectivePatient-centered medical homes are primary care practices that focus on coordinating acute and preventive care. Such practices can obtain patient-centered medical home recognition from the National Committee for Quality Assurance. We c...
Estimating the cumulative rate of SARS-CoV-2 infection 2020 621 Accurate estimates of the cumulative incidence of SARS-CoV-2 infection remain elusive. Among the reasons for this are that tests for the virus are not randomly administered, and that the most commonly used tests can yield a substantial fraction of fa...
Exploring the Impact of R&D on Patenting Activity in Small Women-Owned and Minority-Owned Entrepreneurial Firms. 2019 1065 The relevant economics literature on the impact of R&D on patenting activity falls within two methodological areas of inquiry. The first area might be classified as a test of the Schumpeterian hypothesis. The second and lesser research area might be ...
Going public with public money 2021 824 We analyze what we consider to be an unanticipated consequence of the SBIR program, namely, that firms, publicly funded through the SBIR program, are going public based on their new technology developed with support from the SBIR program. There is a ...
The impact of public R&D investments on patenting activity: technology transfer at the U.S. Environmental Protection Agency. 2018 1069 This paper presents estimates of the impact of public R&D on patenting activity at the U.S. Environmental Protection Agency (EPA). Using a time series of public sector agency data, we estimate the per-capita R&D elasticity of new patent applications ...
The impact of the third sector of R&D on the innovative performance of entrepreneurial firms 2021 777 Entrepreneurial firms that rely on public research institutes, the third sector of R&D, are also firms that are more innovative in terms of introducing new or significantly improved goods or services to the market. This finding is based on an analysi...
The Impact of the Vermont Support and Services at Home Program on Healthcare Expenditures 2018 231 Objective: The Support and Services at Home (SASH) program in Vermont aims to coordinate care and assist participants in accessing the health care and support services they need to maintain their health and age comfortably and safely in their homes. ...
Knowledge begets knowledge: university knowledge spillovers and the output of scientific papers from U.S. Small Business Innovation Research (SBIR) projects 2019 1198 Scientific papers submitted for publication from U.S. Small Business Innovation Research (SBIR)-funded research projects are an innovative output that has yet to be studied systematically. Using a knowledge production framework, we identify empirical...
Many-instruments Asymptotic Approximations Under Nonnormal Error Distributions 2010 2165 In this paper we derive an alternative asymptotic approximation to the sampling distribution of the limited information maximum likelihood estimator and a bias corrected version of the two-stage least squares estimator. The approximation is obtained ...
On the Transfer of Technology from Universities: The Impact of the Bayh-Dole Act of 1980 on the Institutionalization of University Research 2019 1267 While the academic and policy literature has focused on patent counts and patent quality as possible outcome measures to evaluate the impact of the U.S. Bayh–Dole Act of 1980, we argue that the impact of the Act on university effort to transfer its t...
Prescription Drug Abuse and Workplace Absenteeism: Evidence from the 2008 2012 National Survey o n Drug Use and Health 2015 414 Prescription drug abuse has become increasingly prevalent in recent years, yet little is known about its impact on workplaces. This study investigated the relation between self-reported misuse of prescription pain relievers and other drugs and self-r...
A public sector knowledge production function 2019 1215 There are no studies of the R&D-to-patenting relationship at the federal agency level. We estimate a public sector knowledge production function using federal agency patent application data over the years 2003 through 2014. We find that the patent ap...
Public support for research in artificial intelligence: a descriptive study of U.S. Department of Defense SBIR Projects 2022 503 We describe public support for AI research in small firms using data from U.S. Department of Defense-funded SBIR projects. Ours is the first collection of firm-level project information on publicly funded R&D investments in AI. We find that the likel...
