We experimentally examine to what extent long‐term “lender–borrower” relationships mitigate moral hazard. The originality of our research lies in recruiting not only students but also commercial and social bankers. The opportunity to engage in bilateral long‐term relationships mitigates the repayment problem. Lenders take advantage of their long‐term situation by increasing their rates. Consequently, borrowers are incited to take more risk. Improving information disclosure ameliorates the repayment but does not incite lenders to offer more credits. Social bankers exhibit a higher probability of granting a loan and make fairer credit offers to borrowers than the other subject pools do.
The primary purpose of this study is to measure the technical efficiency of 30 doctorategranting universities, the universities or the higher education institutes with PhD training programs, in Vietnam, applying the sensitivity analysis of data envelopment analysis (DEA). The study uses eight sets of input-output specifications using the replacement as well as aggregation/disaggregation of variables. The measurement results allow us to examine the sensitivity of the efficiency of these universities with the sets of variables. The findings also show the impact of variables on their efficiency and its "sustainability".Growing Science Ltd. All rights reserved. 5
L’article compare la méthode DEA au Pendiscan pour apprécier la productivité dans le secteur des services. Chaque outil est étudié sur les plans théorique et pratique, en essayant de répondre à la question : comment mesurer la productivité sans oublier la qualité et la flexibilité ?
Cet article consiste, tout d’abord, à mesurer de plusieurs manières l’efficience de 61 institutions de microfinance (IMF) boliviennes et péruviennes avec la méthode Data Envelopment Analysis. Nos résultats indiquent que les IMF examinées observent des niveaux d’efficience financière élevés et des scores d’efficience sociale plutôt faibles. Les scores d’efficience sont ensuite régressés sur une série de facteurs explicatifs des caractéristiques des IMF. Nous montrons que le statut juridique, la méthode de prêt, l’âge et la zone d’opération déterminent l’efficience sociale. En revanche, ces facteurs influencent de manière beaucoup plus limitée les scores des efficiences financière et globale
