  • Van Klaveren C. and J. Ghysels. Collective Labor Supply and Child Care Expenditures: Theory and Application - TIER research
    Papers UvA Working Papers UM Working Papers RUG Collective Labor Supply and Child Care Expenditures Theory and Application Chris Van Klaveren Joris Ghysels Abstract In this study we examine the collective labor supply choices of dual earner parents and take into account child care expenditures We find that the individual labor supplies are hardly affected by changes in the prices of child care services In addition the child care price effects on the individual labor supplies are much smaller than the wage effects Furthermore we find that the additional earnings due to an increase in household non labor income minus the child care expenditures are mainly transferred to the female partner Related information Related People Prof dr Henriëtte Maassen van den Brink 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 2015

  • De Witte, K. and C. Van Klaveren How are Teachers Teaching? A Nonparametric Approach - TIER research
    UvA Working Papers UM Working Papers RUG How are Teachers Teaching A Nonparametric Approach C Van Klaveren and K De Witte Abstract This paper examines which configuration of teaching activities expressed in e g problem solving homework lecturing maximizes student performance To do so it formulates a non parametric efficiency model that is rooted in the Data Envelopment Analysis literature In the model we account for 1 self selection of students and teachers in better schools and 2 complementary teaching activities The analysis distinguishes both individual teaching i e a personal teaching style adapted to the individual needs of the student and collective teaching i e a similar style for all students in a class Exploiting the data set we compare the actual teaching style as revealed by the teacher in the data to the model estimations As such we analyse which students in the class the teacher is targeting with his her teaching style The main results show that high test scores are associated with teaching styles that emphasise problem solving and homework In addition teachers seem to adapt their optimal teaching style on the 70 percent least performing students JEL Codes C14 C61 C23 I21 Keywords Data Envelopment Analysis Teacher Quality Student Performance Nonparametric estimation Revealed teaching style Related information Related People Dr Chris Van Klaveren 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

  • De Witte, K. and Verschelde, M. (2010) Estimating and explaining effciency in a multilevel setting: A robust two-stage approach. - TIER research
    RUG Estimating and explaining effciency in a multilevel setting A robust two stage approach Various applications require multilevel settings e g for estimating fixed and random effects However due to the curse of dimensionality the literature on non parametric efficiency analysis did not yet explore the estimation of performance drivers in highly multilevel settings As such it lacks models which are particularly designed for multilevel estimations This paper suggests a semi parametric two stage framework in which in a first stage non parametric α efficiency estimators are determined As such we do not require any a priori information on the production possibility set In a second stage a semiparametric Generalized Additive Mixed Model GAMM examines the sign and significance of both discrete and continuous background characteristics The proper working of the procedure is illustrated by simulated data Finally the model is applied on real life data In particular using the proposed robust two stage approach we examine a claim by the Dutch Ministry of Education in that three out of the twelve Dutch provinces would provide lower quality education When properly controlled for abilities background variables peer group and ability track effects we do not observe differences among the provinces in educational attainments Keywords Productivity estimation Multilevel setting Generalized Additive Mixed Model Education Social segregation JEL classification 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

    Papers RUG Accounting for exogenous influences in a benevolent performance evaluation of teachers Students evaluations of teacher performance SETs are increasingly used by universities and colleges for teaching improvement and decision making e g promotion or tenure However SETs are highly controversial mainly due to two issues 1 teachers value various aspects of excellent teaching differently and to be fair 2 SETs should be determined solely by the teacher s actual performance in the classroom not by other influences related to the teacher the students or the course which are not under his or her control To account for these two issues this paper constructs SETs using a specially tailored version of the popular non parametric Data Envelopment Analysis DEA approach In particular in a so called Benefit of the doubt model we account for different values and interpretations that teachers attach to good teaching Within this model we reduce the impact of measurement errors and a typical observations and account explicitly for heterogeneous background characteristics arising from teacher student and course characteristics To show the potentiality of the method we examine teacher performance for the Hogeschool Universiteit Brussel located in Belgium Our findings suggest that heterogeneous background characteristics play an important role in teacher performance Keywords Teacher performance Data envelopment analysis Conditional efficiency Education JEL classification 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
