Estimation procedures for ordered categories usually assume that the estimated coefficients of independent variables do not vary between the categories (parallel-lines assumption). This view neglects possible heterogeneous effects of some explaining factors. This paper describes the use of an...

We examine the effect of testing for Coronavirus on deaths in eight countries over the month of March 2020 by estimating a fixed-effect regression model using the Generalized Method of Moments (GMM). On average, the data reject the hypothesis that "testing" for the virus does not affect death....

We propose a new non-linear regression model for rating dependent variables. The rating scale model accounts for the upper and lower bounds of ratings. Parametric and semi-parametric estimation is discussed. An application investigates the relationship between stated health satisfaction and...

In this paper, a control function approach is developed to deal with endogeneity issue in estimating panel data models with ordered response. This methodology is characterized by a two-step procedure, requiring only standard regression to be implemented in each step. To demonstrate the...

This paper applies a two-step dynamic BBS-GMM panel estimation technique alongside with the Diebold and Yilmaz (2012) index variance decomposition approach. This was done to achieve conditional convergence in the growth equation and also to disaggregate the shock due to the epidemic prevalence....

HIV/AIDS is seen as not only the leading cause of death in SSA region but a major public health challenge. Currently, 13% of total population workforce in the region lives with the epidemic; the above means that one in every ten adults in the region is HIV/AIDS positive. Regrettably so, there is...

Understanding the relationship between disability and employment is critical and has long been the subject of study. However, estimating this relationship is difficult, particularly with survey data, since both disability and employment status are known to be misreported. Here, we use a partial...

This paper examines the relationship between health aid and infant mortality, using data from in total 135 countries, between 1975 and 2010. According to the findings, aid comes to have a statistically significant and positive effect on infant mortality rate, as doubling of aid leads to an...

This paper examines the relationship between health aid and infant mortality, using data from in total 135 countries (for the purposes of this study, developing countries), between 1975 and 2010. Utilizing both conventional Instrumental Variable and System GMM approaches, a tentative conclusion...
