The implemented policies have not been successful in fostering the development of a more efficient market that would ultimately benefit social welfare. Overall, our findings indicate that bigger firms lag behind their smaller counterparts in terms of efficiency, even in the long run. Our findings also suggest that an efficient pharmaceutical wholesaler is currently unable to generate normal profit from the distribution of reimbursable drugs.

Our objective is to estimate the effects that depressive symptoms (among other factors) have on absenteeism while avoiding inconsistency in estimators due to sample selection and endogenous regressor. We are unwilling to impose strong assumptions, which are sometimes not required by theory, so our model is semiparametric. Based on microdata from the European Health Survey in Spain, our results indicate that depressive symptoms have a negative effect on working time and increase absenteeism. We conclude that depressed workers lose on average around 12 more days per year than non depressed ones. Levels of absenteeism are also estimated to be higher on average among obese people and among older people (the effect of age is positive).

On the one hand, because private providers are profit-driven, they are more motivated to compete for demand by enhancing quality if demand is elastic. However, because they are more motivated to maximize revenue, they may sacrifice quality to maximize profit. A crucial factor in determining whether private providers should be encouraged is the extent to which their quality exceeds or falls short of that of the public provider. This study, therefore, investigates whether the public and private differ in providing quality healthcare services using the 2014 Ghana Demographic and Health Survey. Our measure of healthcare quality is based on patient satisfaction level with nine healthcare services (cleanliness, waiting time, comfort and safety, consultation time, privacy, listening, explanation, treatment advice and confidentiality) provided by public and private healthcare facilities. We applied an instrumental variable approach to account for endogeneity issues related to the patient’s choice of healthcare provider. We find that private facility users have a higher probability of being very satisfied with “waiting time”, “consultation time”, “listening”, “cleanliness”, “comfort and safety”, “confidentiality”, and “privacy” than public users, thus suggesting that private facilities provide better service than public. We thus recommend encouraging the private sector to enter the healthcare market.
