There is a well-established debate between Heckman sample selection and two-part models in health econometrics, particularly when no obvious exclusion restrictions are available. Most of this debate has focussed on the application of these models to health care expenditure. This paper revisits...

This paper proposes a new method of measuring obesity using Body Mass Index (BMI) data. Conventional measures which simply count the number of individuals with BMI in excess of an upper limit ignore the extent by which individuals exceed BMI limits and also the increased risk ratios for various...

There is a well-established debate between Heckman sample selection and two-part models in health econometrics, particularly when no obvious exclusion restrictions are available. Most of this debate has focussed on the application of these models to health care expenditure. This paper revisits...

This paper analyses the pure time-series properties of doctors’ fees in Ireland to assess whether a structural change in the series is observed at the time of the change in reimbursement in 1989. Such a break would be consistent with doctors responding to the reimbursement change in a manner...

In Ireland, approximately 30 per cent of the population (medical cardholders) receive free GP services while the remainder (non-medical cardholders) must pay for each visit. In 1989, the manner in which GPs were reimbursed by the State for their medical cardholder patients was changed from...

This paper uses duration analysis to investigate the role of tobacco taxes in starting and quitting smoking. Applying a variety of parametric duration models, including a split population model, to a sample of Irish women, it finds that in general tobacco taxes do influence starting and quitting...

There is now fairly substantial evidence of a socioeconomic gradient in low birthweight for developed countries. The standard summary statistic for this gradient is the concentration index. Using data from the recently published Growing Up in Ireland survey, this paper calculates this index for...

This note examines the sensitivity of tests for homogeneity in demand systems to such factors as omitted variables and dynamic and stochastic specification. It estimates demand systems for Ireland using time-series data for different unconditional demand systems with differing dynamic and...
