A Quantitative Model for Profit-Target Setting Chunming (Victor) Shi (Wilfrid Laurier Univ.) Xuan Zhao (Wilfrid Laurier Univ.) Amy Xia (Middle Tennessee State Univ., USA) Outline I. Background and Motivation II. A Single Division Manager III. A Risk-neutral Upper Manager and n Division Managers IV. A Target-oriented Upper Manager with n Division Managers V. Conclusions and Future Research 2 I. Background and Motivation 3 The Gap Most research assumes Expected utility maximization Expected profit maximization Target-based decision making Individuals and firms are regularly assigned targets. They make decisions to maximize the probability to achieve those targets. 4 Why target-based decision making? It is more natural. It is practically important: Yahoo! in the 3rd quarter of 2005 Reported revenue $875M (a 44% gain) Target revenue $881M Stock down 10% in after-hours trading It is risk-averse Variance Semi-variance Critical Probability 5 Empirical Research on Target-based Decision Making In 20 larger companies, manager’s most typical goal is target return on investment (Lanzillotti, 1958). In 728 British manufacturing firms, typical goals are target profit and target return on investment (Shipley, 1981). For 250 MBA students and 6 professional buyers making newsvendor-type decisions, important objectives include meeting targets on sales and gross margin (Brown and Tang, 2006). 6 Theoretical Research on Target-based Decision Making The classical newsvendor (NV) model with a profit-target (Kabak and Schiff 1978, Lau 1980). The two-product NV model with a profit target (Lau and Lau 1988, Li et al 1990, Li et al 1991): specific distributions. Supply chain coordination when both supplier and retailer are profit-target oriented (Shi and Chen 2007). Contract design when both supplier and retailer are profit maximizers and profit-target oriented (Shi and Chen, 2008). 7 Quantitative Target Setting Most existing research assumes exogenous targets. Targets need to be set properly to be useful Very limited research in target setting in OM. Three papers indirectly relate to quantitative target setting (Lau and Lau 1988, Li et al 1990, Li et al 1991). 8 Business Scenario An upper manager is in control of n divisions facing uncertain demand. Each division manager will be rewarded based on if he can achieve a profit target. Each division manager decides on retail price and stocking level. The upper manager assigns a profit target to each division manager. 9 II. A Division Manager under a Profit Target 10 A Price-setting NV under a Profit Target To decide the order quantity and retail price under a demand distribution Multiplicative Demand Model An individual product tends to have a high price elasticity; Chevrolet automobiles b=4.0 (Gwartney 1976) 11 Multiplicative Demand Model Price affects the scale only! Most frequently used demand specification. Four reasons for its popularity besides it analytic appeal (Monahan et al 2004): Consistent with consumer-utility-maximization theory Nice economic interpretation Amenable to empirical analysis Good statistical fit with available sales data 12 A Price-setting NV under a Profit Target When bc>(b-1), higher b lower profit prob. 13 Achievable Profit Target A target is said to be achievable if the probability of achieving it is larger than 0! 14 III. A risk-neutral upper-manager and n division managers 15 Results n divisions: n products or n regions. The risk-neutral upper manager maximizes total expected profitMaximizes the expected profit for each division. Higher c lower profit target When bc>(b-1), higher b lower profit target. 16 IV. A target-oriented upper-manager and n division managers 17 The Optimization Problem 18 “Fair” Target Setting Two reasons: It is fair; especially when all managers know the targets. It leads to global optimum in some situations. 19 “Fair” Target Setting 20 21 Target setting for two divisions 22 Target setting for two identical divisions 23 The case of b < 2 24 The case of b < 2 25 The case of b < 2 26 VI: Conclusions and Future Research 27 Conclusions We present a first study on quantitative target setting in OM. Optimal profit target for a division decreases in c; and decreases in b in most cases. If the upper manager is risk-neutral If the upper manager is profit-target oriented and “fair” target setting is assumed. For the case of two identical divisions, optimal target of each division is half of the upper manager’s profit when b>=2. 28 Future Research Target setting on multiple performance measures such as profit and revenue. Target setting in multiple periods. Empirical studies on target setting practice. 29 Questions? 30
