Longitudinal associations between neighborhood characteristics and body mass index (BMI; weight (kg)/height (m)2) were assessed from 2000 to 2011 among 5,919 participants in the Multi-Ethnic Study of Atherosclerosis. The perceived availability of healthy food and walking environment were assessed via surveys, and 1-mile (1.6-km) densities of supermarkets, fruit-and-vegetable stores, and recreational facilities were obtained through a commercial database. Econometric fixed-effects models were used to estimate the association between within-person changes in neighborhood characteristics and within-person change in BMI...

Incentives to improve hospital performance under prospective payments may come at a cost. First, there may be a strong incentive for hospitals to choose only low-severity patients. Second, hospitals may have an incentive to reduce the quality of care. I analyze the role of hospital ownership on patient selection and quality of care by comparing private nonprofit and public hospitals. The analysis is performed by using unique hospital admission data for cardiovascular procedures in Norway, covering the period from 1999 to 2006...

Risk factors can drive socioeconomic inequalities in cardiovascular disease (CVD) through differential exposure and differential vulnerability. We show how econometric decomposition directly enables simultaneous, policy-oriented assessment of these two mechanisms. We specifically estimated contributions via these mechanisms of neighborhood environment and proximal risk factors to socioeconomic inequality in CVD incidence. We followed 5,608 participants in the Multi-Ethnic Study of Atherosclerosis (2000-2012) until the first CVD event (median follow-up 12...

OBJECTIVE: To use econometric methods to assess comparative overall survival of mRCC patients managed with initial cytoreductive nephrectomy (CN) versus initial systemic therapy. Randomized data demonstrate improved survival for CN preceding cytokine-based therapy in metastatic renal cell carcinoma (mRCC). This benefit may be attenuated in the contemporary mRCC era given more effective systemic therapies. METHODS: Patients over age 65 with mRCC from the Surveillance, Epidemiology, and End Results (SEER) registries linked with Medicare claims from 2006-2011 were categorized by initial treatment...

INTRODUCTION: Hypertension and diabetes, both independent risk factors for cardiovascular disease, often coexist. The hypertension-increased medical expenditures by diabetes status is unclear, however. This study estimated annual total medical expenditures in U.S. adults by hypertension and diabetes status. METHODS: The study population consisted of 40,746 civilian, non-institutionalized adults aged ≥18 years who participated in the 2013 or 2014 Medical Expenditure Panel Survey...

The role played by working conditions in worker health status has been widely acknowledged in the literature in general but has received less attention in economics, due to the inherent statistical biases and lack of data available to determine the role of simultaneous and chronic exposures. This study aims to estimate the causal impact of detrimental working conditions on the self-declaration of chronic diseases in France. Using a rebuilt retrospective lifelong panel and defining indicators for physical and psychosocial strains, I implement a mixed econometric strategy that relies on difference-in-differences and matching methods to take into account for selection biases as well as unobserved heterogeneity...

BACKGROUND: Achieving the Sustainable Development Goals will require careful allocation of resources in order to achieve the highest impact. The Lives Saved Tool (LiST) has been used widely to calculate the impact of maternal, neonatal and child health (MNCH) interventions for program planning and multi-country estimation in several Lancet Series commissions. As use of the LiST model increases, many have expressed a desire to cost interventions within the model, in order to support budgeting and prioritization of interventions by countries...

We completed a retrospective multivariate panel study to evaluate the effect of Gavi Vaccine Alliance grants on vaccine-preventable disease (VPD) postneonatal mortality. We separately tested a composite VPD mortality rate and five vaccine-preventable mortality rates: pertussis, meningitis, measles, diarrhea, and pneumonia (lower-respiratory infection) as dependent variables. All 77 countries eligible for Gavi assistance from 2000 to 2014 were included in the study. To isolate the effect of Gavi funding in our primary model, we controlled for known and likely predictors of child mortality...

This study aims to examine the impact of renewable and non-renewable energy consumption on the agriculture, industry, services, and overall economic activities (GDP) across a panel of G20 nations. The study makes use of annual data from 1980 to 2012 on 17 countries of the G20. To achieve the study objectives, we apply several robust panel econometric models which account for cross-sectional dependence and heterogeneity in the analysis. The empirical findings confirm the significant long-run equilibrium relationship among the variables...

BACKGROUND: Estimating health care costs, either in the context of understanding resource utilization in the implementation of a health plan, or in the context of economic evaluation, has become a common activity of health planners, health technology assessment agencies and academic groups. However, data sources for costs outside of direct service delivery are often scarce. WHO-CHOICE produces global price databases and guidance on quantity assumptions to support country level costing exercises...

Different academic disciplines exhibit different styles, including styles in journal titles. Using data from the 2014 Research Excellence Framework (REF) in the UK we are able to identify the stylistic trends of different disciplines using 155,552 journal titles across all disciplines. Cluster analysis is then used to group the different disciplines together. The resulting identification fits the social sciences, the sciences and the arts and humanities reasonably well. Economics overall, fits best with philosophy, but the linkage is weak...

Performance-based financing (PBF) is a mechanism by which health providers are paid on the basis of outputs or results delivered. A PBF program was implemented on the provision of HIV, prevention of mother-to child HIV transmission (PMTCT), and maternal/child health (MCH) services in two provinces of Mozambique. A retrospective case-control study design was used in which PBF provinces were matched with control provinces to evaluate the impact of PBF on 18 indicators. Due to regional heterogeneity, we evaluated the intervention sites (North and South) separately...

This work aims to study and explain the business cycle correlations of the Japanese production network. We consider the supplier-customer network, which is a directed network representing the trading links between Japanese firms (links from suppliers to customers). The community structure of this network is determined by applying the Infomap algorithm. Each community is defined by its GDP and its associated business cycle. Business cycle correlations between communities are estimated based on copula theory...

V Stránský, L Thinová
In the year 2010 a continual radon measurement was established at Mladeč Caves in the Czech Republic using a continual radon monitor RADIM3A. In order to model radon time series in the years 2010-15, the Box-Jenkins Methodology, often used in econometrics, was applied. Because of the behavior of radon concentrations (RCs), a seasonal integrated, autoregressive moving averages model with exogenous variables (SARIMAX) has been chosen to model the measured time series. This model uses the time series seasonality, previously acquired values and delayed atmospheric parameters, to forecast RC...

Sihan Xiong, Yiwei Fu, Asok Ray
This paper proposes a Bayesian nonparametric regression model of panel data for sequential pattern classification. The proposed method provides a flexible and parsimonious model that allows both time-independent spatial variables and time-dependent exogenous variables to be predictors. Not only this method improves the accuracy of parameter estimation for limited data, but also it facilitates model interpretation by identifying statistically significant predictors with hypothesis testing. Moreover, as the data length approaches infinity, posterior consistency of the model is guaranteed for general data-generating processes under regular conditions...

In this paper, we investigate the extent to which the economic outcomes of restaurants, bars, and cafés have been affected by the introduction of anti-smoking regulations in Europe. We use an unexploited panel database to collect a comprehensive set of information on financial indicators regarding the balance sheets of private and public companies in various economic sectors. The results show that smoke-free policies did not significantly affect the firms' economic performance, irrespective of the balance sheet indicators analyzed...

The study aims to combine the autoregressive distributed lag (ARDL) cointegration framework with smooth transition autoregressive (STAR)-type nonlinear econometric models for causal inference. Further, the proposed STAR distributed lag (STARDL) models offer new insights in terms of modeling nonlinearity in the long- and short-run relations between analyzed variables. The STARDL method allows modeling and testing nonlinearity in the short-run and long-run parameters or both in the short- and long-run relations...

One of the lasting legacies of the financial crisis of 2008, and the legislative energies that followed from it, is the growing reliance on econometrics as part of the rulemaking process. Financial regulators are increasingly expected to rationalize proposed rules using available econometric techniques, and the courts have vacated several key rules emanating from Dodd-Frank on the grounds of alleged deficiencies in this evidentiary effort. The turn toward such econometric tools is seen as a significant constraint on and challenge to regulators as they endeavor to engage with such essential policy questions as the impact of financial speculation on food security...
