Leadership is about making people perform better, making people better, and, making better people, at the same time

Abstract This article presents an evaluation approach for alternative electronic market designs and examines the impact of introducing an IT-enabled innovation (a social communication tool to support group coordination) in an online group-buying market in terms of group decision-making and economic performance. Drawing on theory from economics, decision theory, and information systems, we present a competitive arousal model for a social buying setting that posits that introducing competitive arousal among buyers reduces buyer profits and that social facilitation can mitigate these costs through better task completion and time to completion rates. Using an economic experiment, we found that rivalry has a negative effect on buyer profits but also that pressure increases the efficiency of social communication in terms of group formation. We discuss the implications of these results.

Ammunition: Essentials of Leadership

I wrote this book as a complement to management material found in a number of business schools. I was inspired by the book called The Goal by Eliyahu Goldratt, from my days as an MBA student. Using fiction to teach concepts taught in business school, I think, are very effective. My aim with the book was to collect stories from a number of people I have experienced in my career and weave them into a single character. The books demonstrates key aspects of management and leadership and as the story evolves, so does the character, in the same way every good manager/leader does in their occupation.

Note to instructors in colleges there is an accompanying instructors guide for use with the books. It contains questions and case material for discussion. Contact me @ Alexander.Pelaez@hofstra.edu for more information.
