This paper estimates the impact of BMI, obesity and overweight on direct medical costs. We apply panel data econometrics and use a two-part model with a longitudinal dataset of medical and administrative records of patients in primary and secondary healthcare centres in Spain followed up over...

The main objective of this paper is to investigate the determinants of collateral requirements on loans that are extended to small and medium enterprises (SMEs) in less–developed countries. Our primary data source is the Business Environment and Enterprise Performance Survey (BEEPS) results...

This paper estimates the increase of direct medical costs of both severe and moderate obesity and overweight with respect to a normal-weight individual using a two-part generalised linear model and a longitudinal dataset of medical and administrative records of patients in primary and secondary...

This paper replicates the estimates of a fractional response model for share data reported in the seminal paper of Leslie E. Papke and Jeffrey M. Wooldridge published in the Journal of Applied Econometrics 11(6), 1996, pp.619-632. We have been able to replicate all reported estimation results...

In many economic settings, the variable of interest is often a fraction or a proportion, being defined only on the unit interval. The bounded nature of such variables and, in some cases, the possibility of nontrivial probability mass accumulating at one or both boundaries raise some interesting...
