3Introduction
CRM is not optional in today’s Business environment
At the core of CRM is Development long-term Relationships Maintenance long-term relationships
Differentiating Profitable and Non-profitable customers In fact, CLV fundamentally measures the financial return of the customer
and the firm relationship (Kumar, Peterson & Leon, 2010)
Using CLV, Firms are capable of
With Customers
Investment on profitable customers
Customer Segmentation
Customized Promotion
New Product Offer
4CLV Definition
Author Definition(Kumar et al., 2004) The sum of cumulated cash flows—discounted using the weighted average cost
of capital—of a customer over his or her entire lifetime with the firm P.61(Jain & Singh, 2002) The net profit or loss to the firm from a customer over the entire life of
transactions of that customer with the firm (Bauer et al., 2003) The profit streams of a customer across the entire customer life cycle. P.333
(Berger & Nasr Bechwati, 2001) The excess of a customer's revenues over time over the company costs of
attracting, selling, and servicing that customer P.49
(Sargeant, 2001) The total net contribution that a customer generates during his/her lifetime on a house-list P.28
(Hoekstra & Huizingh, 1999) LTV is the total value of direct contributions and indirect contributions to overhead and profit of an individual customer during the entire customer life cycle that is from the start of the relationship until its projected ending. P.266
First Group: Emphasize on Profit
5CLV Definition
Author Definition
(Payne & Holt, 2001)The net present value of the future profit flow over a customer’s lifetime P.167
(Venkatesan et al., 2007) The net present value of long-term cash flows from a customer
(Gloy et al., 1997) The net present value of cash flows a customer is expected to generate for a firm over the length of The customer's relationship with the firm P.336
(Peppers & Rogers, 2005) The net present value of the future stream of cash flows a company expects to generate from the customer
(Stahl et al., 2003)The net present value of future cash flows generated by the firm’s assets, discounted at an appropriate interest rate and adjusted for inflation and risk P.267
Second Group: Emphasize on Net Present Value
6CLV Definition
Author Definition(Pfeifer et al., 2005) The present value of the future cash flows attributed to the customer
relationship P.17(Hidalgo et al., 2007) The present value of all future earnings a firm may generate from a customer
P.695(Chen & Fan, 2013) The Present value of future profits obtained from a customer P.123
(Benoit & Poel, 2009) Present value of the future cash flows associated with a customer P.10475
(Dwyer, 1997) The customer’s present value of the expected benefits less the burdens
Third Group: Emphasize on Present Value
7Variables incorporated into CLV Models
Independent Variables (Uncontrollable) Customer Demography Purchase Behavior
Controlled Variables Marketing Intervention Customer-Firm Interaction
(Khan, 2009; Gupta et al., 2009; Kumar et al., 2011; Khajevand et al., 2011)
Number of household members
Nationality
Social Class
Customer Churn
RFM Variables
Customized Promotion
Customer Status (Active, Inactive, Potential)
Examples
8CLV Prediction Methods & Techniques
One-Step Methods (Relationship-Level Models) Linear Regression Quantile Regression Markov Chain Mathematical
Two-Step Methods (Service-Level Models) Pareto/NBD Hierarchy Bays RFM MK-SVR
9Prediction Models Comparison
Providing more insight into the factors that drive customer value
Advantage- Amount of modeling required and the often poorer predictions- Modeling rare event
Disadvantage
- Less Amount of Modeling - CLV estimation is much more Straightforward-Prediction accuracy is higher
Advantage
Due to aggregation, insight into the factors that drive consumer profitability is limited
Disadvantage
Two-Step Models One-Step Models
(Benoit & Poel, 2009; Vankatesan et al., 2010; Donkers, Verhoef & Jong; 2012)
10Prediction Models Comparison
Pareto/NBD
Powerful Predictor in non-contractual
business
Needs very long history of
transaction
MK-SVR
Good in non-normal distribution
(imbalance data)
Consider dynamic prediction
Quantile Regressio
n
High predictive performance
Provide view of relationship between
covariate and dependent variable
Provide prediction interval
Combine best of two approaches
Linear Regressio
n
Challenge in model non-normal data
Markov Chain
Flexible
Supporting Probabability
Having well developed theory
RFM
Predict customer short term behavior
Popular in segmentation
Combine two teqnique
Hierarchy Bays
Conditional Inference on
observed data
Deals better with parameter uncertainty
11Mathematical Models
(1) sales take place once a year (2) both yearly spending to retain customers and the customer retention rate remain constant over time 3) revenues achieved per customer per year remain the same.
(1) Sales occur more frequently than once a year (2) both yearly spending to retain customers and the customer retention rate remain constant over time 3) revenues achieved per customer per year remain the same.

profit Serv Usage M in
In multi-service industries, Profit is defined as:
CLV for Customer i at time t
Pre-determined Discount rate
Finite time horizon
number of different services sold
dummy indicating whether customer I purchases service j at time t
amount of that service purchased
average profit margin for service j
(Berger & Nasr, 1998; Benoit & Poel, 2009; )
13RFM Model
RFM
Recency: the period since the last purchase; higher probability of a repeat purchaseFrequency: number of purchases made within a certain period; higher frequency indicates greater loyaltyMonetary: the money spent during a certain period; a higher value indicates that the company should focus more on that customer
WRFM
-Weighted RFM- instead of RFM. They dedicated weights to Recency, Frequency, and Monetary. depends on characteristics of the industry, different weights should be assigned to RFM parameters.
RFMTC
Recency, Frequency, Monetary value, Time since first purchase, and Churn probability using Bernoulli sequence in probability theory.

linking with other approaches such as
Pareto/NBD and Markov Chain Model. Pfeifer and Carraway (2000) are the
first researchers who introduced the idea of
combining two techniques to
overcome limitations of each method.
14MK-SVR Framework
Controlled Variables
Independent Variables
String Kernels
Gaussian Kernels
Ensemble Prediction
Promotion Optimization
Dynamic Prediction
UpdateLongitudinal
Data
MK-SVR
(Chen & Cheng, 2013)
Major Contributions
1. Longitudinal data are first introduced into the CLV prediction model to facilitate the dynamic prediction and improve the prediction performance.
2. An improved MK-SVR approach is proposed to simultaneously model the controlled and independent variables using multiple kernels.
3. A controlled variable about multiple promotion activities is incorporated into the dynamic CLV predictionmodel, and the dynamic customized promotion policy is determined by maximizing the CLV.
15Prediction Performance Metrics
Quantile Regression
Linear Regression
Quantile Regression
SVR
• Measures of the deviation between the actual and predicted values
MAE (Mean Absolute Error)
• Appropriate for prediction interval comparison from one data set not multiple
RMSE(Root Mean Squared
Error)
• percentage of customers whose predicted CLV falls into the same category as their true CLV
Hit-Rate
• provides an indication of the correctness of the direction
DS(Directional Symmetry)
(Donkers & Verhoef, 2007; Benoit & Poel, 2009; Abdolvand, Albadvi & Koosha, 2009; Chen & Fan, 2013)

17Conclusion
Current limitations of CLV are applicability and utilizing its potential in improving business strategies. limitations of predicting customer behavior, accuracy, the lack of empirical implementations, implementation challenges, the lack of integration between customer data, and marketing efforts CLV models ignore the potential risks
Future Research Calculating referral Value of customer Take Risk into account in CLV Extend Gupta et al (2009) to analyze sensitivity of each CLV variables Determine the multiple personalized marketing interventions to maximize the CLV
over time. The optimization of the best composition of the promotions
