Inefficiency in Childcare Production. Evidence from Italian Microdata

The purpose of the paper is to study inefficiency in the production technology of the childcare service and to carry out a comparative analysis of public and private day-care centres. An empirical analysis on cross-section micro-data from a region of northern Italy has been conducted by using an input-distance function with a translog specification. Estimates of the multi-output production technology and input-oriented technical inefficiency are obtained in a stochastic frontier model with a half-normally distributed one-sided error. Heteroscedasticity has been modelled to investigate the determinants of inefficiency and estimate their marginal e ects. We find that production exhibits increasing returns with an estimated elasticity of scale of 1.21. Separability between inputs and outputs is rejected at a 5% level of significance. The average estimate of technical inefficiency is 10% and public centres are more ine cient than private centres by 4.1 percentage points. The proportion of part-time children and the presence of mixed-age classrooms are significant determinants of inefficiency which equally a ect both public and private centres.
