Learning curves in collaborative planning,forecasting, and replenishment (CPFR) information systems: An empirical analysis from a mobile phone manufacturer

While Collaborative Planning, Forecasting, and Replenishment (CPFR) information systems have been increasingly deployed to improve supply chain operations in a cross section of industries, the extant literature has largely overlooked the learning effects within organizations, thereby resulting in incomplete assessment of their business value. Using an operational-level panel data for nine product lines over 2.5 years, we empirically examine the learning curves in CPFR between Motorola, a mobile phone manufacturer, and one of its U.S.-based national retail partners. We found that the two key components of CPFR, collaborative forecasting (CF) and collaborative replenishment (CR), exhibit distinct learning curves. Forecast accuracy improves immediately following CPFR implementation but the rate of improvement slows over time, whereas inventory levels increase at first and begin decreasing after a period. Further, we found different learning effects in terms of inventory levels when products are later replaced with new form factors. Product replacements have lower inventory levels than their antecedents, at least for low-end products. We discuss important implications for theory and practice at the interface of information systems and operations management.     

Sales force modeling: State of the field and research agenda

Inspired by Erin Anderson’s contributions to sales force research, this paper focuses on research that utilizes quantitative models to investigate important questions in sales force management. The purpose is to summarize several significant developments in knowledge over the last 40 years and identify major opportunities for impactful theoretical, empirical, and decision model-based research in the future.     

Effects of relationship climate, control mechanism, and communications on conflict resolution behavior and performance outcomes

In this two-year study we develop and test a comprehensive model of conflict management. The conceptual model commences by demonstrating the importance of channel members’ past history of interactions as ‘setting the stage’ for members’ present ability to interact, that is, communicate, resolve conflict disputes, and ultimately, culminate in performance outcomes (financial as well as relational). In effect, we track the full gamut of conflict management related constructs in the conceptual model, from antecedent conditions to the consequents of conflict management. Empirical results, utilizing a sample of 282 retailing agents affiliated to a large North American supplier (principal) across two years, indicate strong evidence for fourteen of the eighteen hypotheses drawn from our conceptual model. Specifically, among other effects, data reveal that past history of cooperative versus conflictive orientations and bureaucratic versus trust-based governance mechanisms significantly influence the communication strategies adopted, which in turn determine whether the distributive or integrative conflict resolution behaviors are adopted. Further, the choice of conflict resolution behaviors adopted commensurately influences relational performance, and the type of communication strategy adopted influences financial performance. The paper concludes with a series of managerial implications and an agenda for future research.     

Organizing for empowerment: an interview with AES's Roger Sant and Dennis Bakke. Interview by Suzy Wetlaufer.

The topic of empowerment is receiving a lot of attention, but how many employees are truly empowered? At the global electricity giant AES Corporation, the answer is all 40,000 of them. In this interview, chairman Roger Sant and CEO Dennis Bakke reflect on their trials and triumphs in creating an exceptional company and explain how their employee-run company works. When they founded AES in 1981, Sant and Bakke set out to create a company where people could have engaging experiences on a daily basis--a company that embodied the principles of fairness, integrity, social responsibility, and fun. Putting those principles into action has created something unique--an ecosystem of real empowerment. What does that system look like? Rather than having a traditional hierarchical chain of command, AES is organized around small teams that are responsible for operations and maintenance. Moreover, AES has eliminated functional departments; there's no corporate marketing division or human resources department. For the system to work, every person must become a well-rounded generalist--a mini-CEO. That, in turn, redefines the jobs of the people at headquarters. Instead of setting strategy and making the "the big decisions," Sant and Bakke act as advisers, guardians of the principles, accountability officers, and chief encouragers. Can other companies successfully adopt the mechanics of such a system? Not unless they first adopt the shared principles that have guided AES since its inception. "Empowerment without values isn't empowerment," says Sant. "It's just technique," adds Bakke.     

The Role of Credit in the 2007–09 Great Recession

This paper examines the financial crisis of 2007/9 and the downturn in the U.S. We argue that effective demand over the 2001?C2006 expansion was maintained by credit. The role of credit in a Vector Error Correction Model and Granger-causality between aggregate spending, credit, disposable income, and profits are examined. We show that credit itself is determined by factors outside the circular flow of income. The results raise new hypotheses about the crucial relationships in macroeconomics that sustain aggregate spending. We then compute the generalized impulse responses in the VECM to demonstrate the severity of the downturn and show that legislative changes that dismantled the restrictions placed on the financial sector and the consequent structural changes after 1980 enabled the growth of new debt instruments and credit. The overexpansion of credit when profits and house prices were declining in 2005/06 and informational asymmetries on the quality of credit and its sudden withdrawal in 2007 paralyzed the economy and led to the Great Recession.
