In the present paper author attempts to support through an econometric panel data analysis the view of (Darmon and Drewnowski, 2008) that higher income classes have healthier diet, therefore lower obesity levels. The sample covers Western Europe and the United States. Data are taken from...

The paper investigates the effects of nursing overtime on nosocomial infections and medical accidents in a neonatal intensive care unit (NICU). The literature lacks clear evidence on this issue and we conjecture that this may be due to empirical and methodological factors. We thus focus on a...

Evidences from nonparametric and semiparametric unbalanced panel data models with fixed effects show that Kuznets' inverted-U relationship is confirmed when economic development reaches a threshold. The model tests justify semiparametric specification. The integrated net contribution of control...

This research paper aims at investigating the social factors affecting poverty in selected developing countries which was hardly been investigated, yet. We incorporated income poverty index (poverty headcount ratio and poverty gap) and human poverty index as dependent variables, while social...

How should researchers design panel data experiments? We analytically derive the variance of panel estimators, informing power calculations in panel data settings. We generalize Frison and Pocock (1992) to fully arbitrary error structures, thereby extending McKenzie (2012) to allow for...

In the present paper, author will attempt to point out empirically that if alcohol is used in moderation up to a certain critical volume, then this will have a positive impact on human life expectancy, but beyond that critical volume life expectancy will be reduced. The sample covers all...

In the present paper it will be shown empirically that smoking decreases labour productivity. Panel data analysis is based on a single equation model estimated through the Eviews software package. Our sample refers to the period 1993-2008 and covers many western countries, the United States and...

In the present paper through an empirical analysis author will point out with pane data analysis that obesity has a negative impact on life expectancy, thus supporting the view of (Joint Regional Board, 2009); (Edward, 2001). The sample covers most Western world. Data are drawn from OECD and are...

In the present paper through an empirical analysis using panel data it will be pointed out that alcohol consumption impairs fertility, thus supporting the findings of (Anderson and Baumberg, 2006). The sample covers Western Europe. Data, which are taken from Eurostat and OECD, are elaborated by...
