  • De Witte, K. and Kortelainen, M. (2008), Blaming the exogenous environment? Conditional efficiency estimation with continuous and discrete environmental variables. - TIER research
    Papers UvA Working Papers UM Working Papers RUG Blaming the exogenous environment Conditional efficiency estimation with continuous and discrete environmental variables This paper proposes a fully nonparametric framework to estimate relative efficiency of entities while accounting for a mixed set of continuous and discrete both ordered and unordered exogenous variables Using robust partial frontier techniques the probabilistic and conditional characterization of the production process as well as insights from the recent developments in nonparametric econometrics we present a generalized approach for conditional efficiency measurement To do so we utilize a tailored mixed kernel function with a data driven bandwidth selection So far only descriptive analysis for studying the effect of heterogeneity in conditional efficiency estimation has been suggested We show how to use and interpret nonparametric bootstrap based significance tests in a generalized conditional efficiency framework This allows us to study statistical significance of continuous and discrete exogenous variables on production process The proposed approach is illustrated using simulated examples as well as a sample of British pupils from the OECD Pisa data set The results of the empirical application show that several exogenous discrete factors have a statistically significant effect on the educational process Keywords Nonparametric estimation Conditional e ciency measures Exogenous factors Generalized kernel function Education JEL classi cation C14 C25 I21 Related information Related People Prof dr De Witte Kristof Working Paper Download TIER About Tier About Tier UvA About Tier UM About Tier RUG Tier Business Plan TIER Midterm Report 2010 Vacancies People All People People UvA People UM People RUG Visiting scholars Working Papers All Working Papers Working Papers UvA Working Papers UM Working Papers RUG Education Programme Master MEBIT Master MEPE Premaster MEBIT Academische Meesterwerken Enrollment Courses Graduate program Workshops Seminars Workshop on Education Economics News LEER Workshop on Education Economics Nederland in ideeën

    Papers UvA Working Papers UM Working Papers RUG Does School Time Matter On the impact of compulsory education age on school dropout 2010 Cabus Sofie J and Kristof De Witte Abstract A straightforward way to prevent students from leaving education without a higher secondary diploma consists of increasing the compulsory education age By staying longer in school the idea is that more students eventually obtain a higher secondary diploma This paper examines by a difference in differences analysis the causal impact of a one year increase in compulsory school age on dropping out at secondary education To do so we exploit a recent compulsory education policy reform in the Netherlands After controlling for confounding factors and observable covariates significant results of about 2 5 percentage points fewer dropouts are found The effect however is entirely situated in the student group non liable to the policy reform We observe that native Dutch vocational students mostly without retention in grade but also without a higher secondary diploma at hand more often left school in the immediate period before the policy reform Given the economic revival at that time this fact may suggest anticipation on labor market opportunities Keywords Compulsory education age difference in differences school dropout Related information Related People Dr Cabus Sofie Prof dr De Witte Kristof Related Projects Meaning of standards based education Working Paper Download TIER About Tier About Tier UvA About Tier UM About Tier RUG Tier Business Plan TIER Midterm Report 2010 Vacancies People All People People UvA People UM People RUG Visiting scholars Working Papers All Working Papers Working Papers UvA Working Papers UM Working Papers RUG Education Programme Master MEBIT Master MEPE Premaster MEBIT Academische Meesterwerken Enrollment Courses Graduate program Workshops Seminars Workshop on Education Economics News LEER Workshop on Education Economics Nederland in ideeën
