Working Papers

Seria wydawnicza WNE WORKING PAPERS prowadzona jest przez WNE UW od 2008 r. i jak dotąd opublikowano w niej ponad 400 prac.

Seria WNE Working Papers służy szybkiemu upowszechnianiu wyników badań prowadzonych na Wydziale Nauk Ekonomicznych UW. Publikowane tu teksty mają charakter wersji roboczych (pre-printów): mogą być uzupełniane lub poprawiane w miarę postępu prac nad tekstem i procesu wydawniczego. Prezentujemy aktualną wersję udostępnioną przez autorów, opatrzoną datą oraz identyfikatorami DOI/ISSN – co ułatwia jej cytowanie i śledzenie kolejnych iteracji. Każdy dokument zachowuje pełne prawa autorskie swoich twórców, a w przypadku późniejszych zmian, autorzy mogą w dowolnym momencie zamieścić zaktualizowany plik lub wskazać miejsce ostatecznego wydania.

Do serii WORKING PAPERS przyjmowane są artykuły pracowników naukowych WNE UW oraz publikacje z konferencji organizowanych na WNE UW. Artykuły powinny dotyczyć ekonomii, mieć charakter oryginalnych prac badawczych, nie być wcześniej publikowane. Przyjmowane są wyłącznie teksty w języku angielskim.

WP318. How do managers actually choose suppliers? Evidence from revealed preference data

Supplier selection plays a pivotal role in the success of any organization as it significantly reduces purchasing costs and increases corporate competitiveness. At the same time, it is a very challenging task as decision-makers have to tradeoff among different supplier attributes. In this paper, a discrete choice model of supplier selection is developed, based on revealed preference data collected from an electrical equipment manufacturer in Poland. We explore the importance of different attributes for the initial choice and subsequent switching of suppliers. The proposed logit model is proceeded by a nonparametric analysis conducted through the Chi-square Automatic Interaction Detector (CHAID) framework, which serves exploratory purposes. We find that delivery and reliability play a crucial role in decision-making with regards to choosing suppliers and switching them if necessary.

WP317. Supplier selection in emerging market economies: a discrete choice analysis

This study presents the perceived importance of different supplier attributes for managers' choice of suppliers in emerging market economies. We analyze the supplier selection process based on multiple attributes categorized into six groups: quality, cost, delivery, product, service, and business. Empirical data for this study was collected from 163 corporate executives in the automotive and fast-moving consumer goods industries operating in Poland and India.
A two-part survey was conducted; the first part consisted of a Likert scale set of questions aimed at determining the perceived importance of supplier attributes. The second part of the survey was a discrete choice experiment that examined the actual choices of experimental supplier profiles made by executives. Comparing our results to previous works in this domain, we find that the importance of the cost attribute has decreased over the past two decades, whereas the relevance of delivery and product has increased. Each of the six supplier attributes was broken down into sub-attributes, which provided us with an insight into the decision-making process. The results indicate that with respect to delivery, delivery lead time, responsiveness to demand fluctuations, and compliance with due date had a significant effect on executives' decisions. At the same time, new product availability and product range played crucial role amongst product attributes. Finally, the dataset was split into different sub-groups, based on the two industries and two countries analyzed, to examine industrial and cultural differences.
