Theory of binary-valued data envelopment analysis: an application in assessing the sustainability of suppliers

Karimi, Balal; Azadi, Majid; Saen, Reza Farzipoor; … - In: Industrial Management & Data Systems 122 (2022) 3, pp. 682-701

Purpose The objective of this study is to present a binary-valued data envelopment analysis (DEA) theory. The authors’ proposed approach, for the first time, combines binary-valued and integer-valued theories concurrently in the DEA context. To do so, new production possibility sets (PPSs)...

Does the Open Limit Order Book Reveal Information About Short-run Stock Price Movements?

Hellström, Jörgen; Simonsen, Ola - Institutionen för Nationalekonomi, Umeå Universitet - 2006

This paper empirically tests whether an open limit order book contains information about future short-run stock price movements. To account for the discrete nature of price changes, the integer-valued autoregressive model of order one is utilized. A model transformation has an advantage over...

Additive super-efficiency in integer-valued data envelopment analysis

Du, Juan; Chen, Chien-Ming; Chen, Yao; Cook, Wade D.; … - In: European Journal of Operational Research 218 (2012) 1, pp. 186-192

higher discrimination power among decision making units, especially for integer-valued data. We use an empirical application … targets to the nearest integers can lead to misleading solutions and efficiency evaluation. Addressing this kind of integer-valued … data, the current paper proposes models that deal directly with slacks to calculate efficiency and super-efficiency scores …

A Bivariate Count Data Model for Household Tourism Demand

Hellström, Jörgen - Institutionen för Nationalekonomi, Umeå Universitet - 2002

Households' choice of the number of leisure trips and the total number of overnight stays is empirically studied using Swedish tourism data. A bivariate hurdle approach separating the participation (to travel and stay the night or not) from the quantity (the number of trips and nights) decision...
