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

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).

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).

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.

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.

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.

“Fair” Target Setting

Target setting for two divisions

Target setting for two identical divisions

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.
