Regression spline bivariate probit models: A practical approach to testing for exogeneity

Bivariate probit models can deal with a problem usually known as endogeneity. This issue is likely to arise in observational studies when confounders are unobserved. We are concerned with testing the hypothesis of exogeneity (or absence of endogeneity) when using regression spline recursive and sample selection bivariate probit models. Likelihood ratio and gradient tests are discussed in this context and their empirical properties investigated and compared with those of the Lagrange multiplier and Wald tests through a Monte Carlo study. The tests are illustrated using two datasets in which the hypothesis of exogeneity needs to be tested.     

Students’ views on thesis supervision in international master’s degree programmes in Finnish universities

This paper employs an intercultural perspective to examine students’ views on master’s thesis supervision and the roles and responsibilities of supervisors and students. The 302 respondents who answered the online questionnaire were enrolled in international master’s degree programmes in four Finnish universities. The study revealed asymmetric views by students regarding the division of responsibilities between themselves and their supervisors. It was found that very few students and supervisors discuss the differences in study cultures between Finland and students’ countries of origin, their cultural backgrounds or the aspects of Finnish society that students do not understand. The research suggests that supervisors and students need to conduct early discussions on supervision and culture.
