INFORMS Revenue Management and Pricing conference - some feedback!

Dear Readers,

Earlier this summer, Julien went to the INFORMS Revenue Management and Pricing conference at Columbia University. Held in NYC, this event “is the premier forum for both academics and practitioners who are active in research in the fields of pricing analytics and revenue management”. The objective was to get up to speed with the latest research, practicesand burning topics in the industry.


He was amazed to see how Revenue Management and Pricing (RMP) techniques are developed and widely used in the United States. Most of the conference participants originate from the US and this discipline seems far more advanced there than in Europe. There are business cases in many unconventional areas (e.g. Google, with its Ad Exchange is using RMP techniques to grow the online advertising pie in an unconventional way – more about that in an incoming article), and the markets have really understood the potential of the price dimension in the 4 Ps marketing mix.

We would like to share a few findings with you…

1) The prerequisites for RM revisited 
This conference enabled us to put this discipline in perspective; it also got us to rethink several ideas we had about pricing:
  • Market power: it is commonly accepted that individual consumers represent a fragmented demand, which doesn’t have much bargain power when it comes to pricing. This statement doesn't hold in a context of "social learning", where information is shared, and expectations tend to converge.
  • Market segmentation. For a while, we were wondering which came first: the chicken (pricing) or the egg (revenue management)? Well, for sure, pricing is not a sub-set of RMP (as well as inventory management is)- it goes along with it and is on a higher level of analysis. It has a strategic aspect that would lead RMP in the organization. Actually, proper market segmentation (and calculation of pricing break-even points) is probably the real pre-requisite to any price related activity. 
  • Price as a signal: It tends to be accepted that RMP cannot be implemented in an organization where the price a signaling characteristic regarding the product. Research has gone further and presents the price as a signaling device of product availability (demand forecast vs. inventory available). On this regard, we are looking forward to the publication of "Markdown Management: Pricing as a Signaling Device", by Gad Allon (Northwestern University), AchalBassamboo (Northwestern University), Ramandeep Randhawa (University of Southern California). Adapting pricing to product availability is an issue that most companies are facing : Who has never wondered what is communicated by the price a good is sold (eg. Used items on ebay, amazon marketplace, craigslist etc)?
Above all, the concept of perishability remains: a product/service is lost when not sold due to a limited life span. Of course, some pre-requisites vary, and must be stabilized on a case by case basis.

2) A taxonomy of RM
Acknowledging RMP by sector is, we believe, not the right level of analysis. After having attended this conference, and thus analyzed the latest research, we believe that RMP could be classified into three core areas.

RMP focuses on the “Maximization of Revenue” through:
  • A proper segmentation and an optimized pricing policy: This is a key component when willing to market you product differently to different groups (bundling questions, break-even point for segmentation, demand and promo management). This must be sufficient when no real binding constraint can be found 
  • The management of a limited inventory: This is the origin of RMP 
  • The management of a network’s congestion where capacity has a very limited life span, and could not be stocked: This is under implementation by Telcos, Energy providers … Stochastic demand analysis is at the heart of it. 
3) The power of social learning in RMP
As mentioned previously, strong social learning reshapes a market's forces.

A very interesting presentation dealt with the issue of whether the customers manage to get a rationale and can understand basic RMP concepts. Therefore, they could act upon it and compare the quality of products (don’t mix the comparability of products and their lookalike)

Our model postulates a fairly simple learning mechanism. Given the number of past agents that purchased and of them the number of agents that liked the product, each agent forms an estimate of the quality sensitivity parameters (QSP) of the marginal agent that purchased and liked the product. The agent then compares this marginal QSP to his own QSP.” In "Monopoly Pricing in the Presence of Social Learning", by B.Ifrach, C.Maglaras, and M.Scarsini.

This presentation offers a vision of customer behavior and its impact on market actors. More to come in a separate article

4) The impact of research on RM practices
The RM industry is interesting in its ability to absorb state-of-the art research, and to always go further into details. Lately, this has resulted in an ability to:
  • Build disruptive and even more robust RMP : several business case emerged for various new industries. Demand shocks management is one of them. 
  • Use an industry minded research, with a focus on reality: Cancel and rebooking behavior and how to act upon 
  • Build incremental innovation: Bundling services and its efficiency 
  • Gather a growing number people from various horizons and nationalities 
5) RMP and value creation revisited
Boarder line subjects are lightly emerging and we are thrilled to see that coming.

Once again, through this blog, we are trying to explore how organizations can implement Revenue Management and Pricing techniques.

The first hurdle we have to overcome is the financial evaluation of a RMP project. Several options are available: i) The traditional NPV, ii) an NPV model associated with a Monte Carlo simulation (used by Hilton Hotels’ Revenue Management), iii) through an option-like valuation (This method, and the business case for RMP will be available later on this blog). Let’s not neglect the other aspects: the strategic fit, Finance and cash flow considerations, the existing IT infrastructure, People and the corporate culture, and the Marketing and Communication.

Implementing RMP should also mean bringing superior value to the organization. That is the article that we have initiated earlier and that we will keep on updating.

In short, this conference helped us realize how fast the Revenue Management and Pricing field is moving. In order to get a grasp of how innovative and far reaching RMP is, we will publish a couple of industry focused articles within the next few weeks.

Thanks for following us!

Revenue Management: a fresh perspective from the field


Two months ago, we published a survey aimed at RM professionals, in order to add a practical perspective to our articles.

This survey had a relatively explorative goal – even though it had some closed-ended questions: We wanted to get professionals to put their own words on what they do.

It is not surprising that most of our respondents are currently working in the airline industry. Yet, we received contributions from the outdoor advertising, timeshare, hotel, and car rental industries.

We would like to thank all the respondents for their insights, and for their time. As we analyzed the results, we were glad to see certain issues that we had not completely addressed in the blog at that time - this will change soon.

The following are the main findings of our survey.

Organization – role in the company
All professionals believe that their role is crucial for their company’s success. The majority of them report directly to the top management, even if certain professionals have an extra hierarchical layer – sometimes, they report to the Revenue Management / Planning department.

As one of our respondents (obviously an airline RM professional) said: “The RM department should be the heart of the company, its main engine. It is the sector that assists in route planning, strategic planning and business strategies and marketing actions. Therefore, it should receive the best structure in the company.”

Pros and cons
Our respondents view Revenue Management as a sound, scientific and well justified approach to optimize revenue, and thus to boost the bottom line.

On the other hand, it seems that the main issue Revenue Management has to address is corporate culture. Top management does not always "trust" Revenue Managers, and does not always believe in RM’s potential. It can result in a poorly adapted organizational structure, and sloppy decision making process. In sufficiently large organizations, it appears that some Revenue Managers have trouble in getting credibility from other departments: The marketing department accuses them of neutralizing their efforts, whereas the sales department complains about removed responsibility.

Due to the same cultural issues, outsourcing Revenue Management does not seem completely feasible yet. As suggested, the data analysis part could be outsourced, while the interpretation part should stay within the company, close to the top management.

Metrics used / Analytics
Not surprisingly, most respondents declared that they use the following main structural variables:
  • Revenue (price)
  • Booking/reservation/inventory information (quantity) 
  • Forecast data
The other indicators used include: competitors fares, sales channels, market changes, demand elasticity and costs.

Implementing Revenue Management
As one of the respondents summarizes it, “RM is far reaching”. Revenue Management is applicable to a wide scope of businesses, from the obvious to the not so obvious: Hotels, sales online in general, parking lots, hairdressers, supermarkets and retail as a whole.

If the pricing is dynamic in the airline industry, whether it should be uniform or dynamic when applied to other areas depends on the sector and the particular needs of the business.

Introduction to Revenue Management as a sustainable value creator for the company

Value creation is driving companies at every stage of their activity: from products to shareholders, including employees, the community, the environment, etc. The definition of Value creation is wide, and there is no consolidated literature about it: IndustryWeek has a whole section dedicated to value creation, and companies have their own view on this issue (see what value creation is according to BHP Billiton). The finance oriented approach is central. Corporate Finance from Brealey Myers & Marcus explains extensively own a project "creates value" for its owner/investor. Marketing Managementfrom Kotler and Keller, drags the concept of value creation all along the book. Strategy mainstream authors, and especially Michael Porter  in his early papers (Competitive Advantage, 1985) prefer to define it using the concepts of competition and the company : Competitive advantage brings a sustainable added value vs. competition and the market. We believe this last definition symbolizes the most Revenue Management in its expected effects. Now, let's try to make our own generic and simple definition... there we go: Value creation is what brings a superior worth to a good or a service, on the perspective of a market. A good can be a company, a business unit, a product and it is to be viewed as positioned within an environment.

This is much discussed at every level of the corporate ladder. We believe this question is key for any RM implementation proposal. It is the role of the manager supporting the idea to bring some milestones along.
Evaluating the financial benefits of the implementation of an RM system in a company quickly proves to be complicated: We will dedicate an article to address this issue. Indeed, one can calculate an expected rate of return on an investment in software, machines or any tangible asset, where the material’s life span, cash flows and depreciation period are known a priori. 

Here, we are talking about a change that is probably one of the most difficult to assess in a company: The impact of a new, structural management methodology, which is all but certain. The greater the expected returns are, the higher the risk is (yes... we have heard of this too!).
In this context, we think the concept of sustainability makes sense. Implementing a new management methodology is a long term project. To create value, Revenue Management first has to be seen as at the crossroads of strategy, finance and organizational theory; and secondly, optimization, demand forecast and customer behavior issues can be addressed. Building a transverse management methodology is a key prerequisite to generate organizational alignment and thus survive external events.
That is why we believe that a structured approach must be drawn: This article proposes a series of steps that would enlighten the feasibility study to support such a project. We therefore list a couple of steps or milestones that one should address when you coming with the idea of implementing Revenue Management.

Step 1: Be aware that you may find yourself in a difficult position
Due to the influence of capital markets and private equity (and the related expected returns), business today (and probably yesterday as well) tends to focus on high yield and short term payback, The investor follows the risk paradigm and expects a proportional (or at least not contrary) return / yield. Therefore, everyone can understand that an investor, who is endowing in a firm in capital need to finance projects, is experiencing a risk, especially if the investment is about implementing a new, challenging management technique!

From our experience and readings (see Talluri and Van Ryzin, The Theory and Practice of Revenue Management), it takes quite some time to implement Revenue Management; even more if it is the first time: the needs have to be properly defined and studied, the organization’s rules, design and processes have to be reengineered to support RM. This means that, whatever the size of the business, a transition time is needed to get from the current to the targeted /optimal situation. An implementation can take several months up to several years. 

This puts the manager in charge of the implementation in a difficult position: Investors could expect a “return” before the end of it, and will ask for an assessment of the first results of the newly implemented Revenue Management system. There is an inherent contradiction between a latent short-termism, and RM’s value creation which can take a bit of time before ramping up. This underlines the importance of sustainability.

Step 2: Build something called strategy, or at least, steer your organization. 
First of all, Revenue Management is not a secret formula, enabling managers to create growth and value, forever (neither is value creation in general by the way). We think that such a sustainable value creation is the coordinate action of an organization with aligned people, methodologies, and stakeholders, willing to make the move and bring the company to the next level. This implies the alignment on long run business objectives and changes together with a short run operational management. Making this change be part of a strategic positioning would have more success and meet expectations (Michael Porter,  What is strategy?, HBR Nov-Dec 1996) This whole is called “strategy”, and 2 companies out 3 lacks one – according to Henri Bouquin, Head of EMBA at Université Paris Dauphine, France in his book, Les fondamentaux du contrôle de gestion.)

Step 3: Try to assess a time period for Revenue Management. 
Revenue Management has currently no standard usage time (even if depreciation is a calculation made by accounting…but everyone knows how accounting can sometimes not represent reality!). This is a key as depreciation is based on utilization rate or time of the asset Obsolescence, from to our point of view, can only come from superior optimization and forecasting algorithms within the competition, preventing your company to reach all your usual revenue streams. To our opinion, the prerequisite to the kick-off of a project, before convincing any investor and being misled thereafter, is assessing timing and usage time. For example, usage time could follow the life cycle of the product or the foreseeable market macro-changes. This way, you can adapt your management to your activity. Basic idea, but robust in a globalized world!

Step 4: Assess revenue increase and value creation.
This will be the full content of an article to be published later in May

Step 5: Keep in mind your (high) fixed costs and the levers to keep Revenue in a good shape
Rule of thumb: Revenue Management will create positive results as long as the activity of your company is not affected by uncontrollable exterior factors (we’re pretty smart on this blog J). If the activity slows down, revenues may lower, and it will be quite critical to determine whether or not Revenue Management is generating superior value for the company. In this context, value is strongly needed by the organization which has, more than ever, to sell to high yield customers. This is when capacity adjustments have to come into play. Indeed so far, one of the hypotheses was a fixed capacity. However companies can to take advantage of that and must have rescue plan that assess the opportunity cost of shutting down part of the capacity.

Even if Revenue Management works well in capacity constrained industries, it doesn’t mean that it should not be changed if needed. This is easy for some businesses like hotels and cruise lines for example, where you can scale down more or less rapidly (selling part of your assets) and try to diminish slightly your costs. Unfortunately, other businesses (parking lots, restaurants for example) have more difficulties to reduce their capacities due to limited levers. Indeed it is not easy to fire employees in restaurants in Europe (ok… in France!) to wait fewer tables for example. Anyhow, shutting half of a car park or of a restaurant off would not have any effect on reducing the costs, as opportunity costs remain for the whole occupied space.

Step 6: Have a look around.
Of course, your market is not revolving around you and key players could look at each other and find ways to set up alliances, leaving you behind, alone. This has happened recently in the airline industry: the three main alliances (Star Alliance, Skyteam, Oneworld) created JV to form oligopoly in some transatlantic markets. This leaves remote players like SAS, Finnair with low market shares. Their only alternative to keep the statu quo is low prices. This is for sure a more of a strategic subject, but RM is a topic for alliances (Can we align our pricing policy? Who will manage the inventory?).
Well, as an entrepreneur or a small business owner, you may not feel concerned with what is said above (even if we think that for every company size, there are markets and predators which will, as it is the goal of most corporations, grow!). We still believe distribution is a core lever for the successful implementation of revenue management. Indeed History shows that the first Global Distribution System (GDS) brought the first RM. Today, with the new techs, multi-channel distribution becomes easier than ever: Less complicated selling platforms have to be built (unlike GDS in the business travel industry. We are actively researching how could SMEs build their own distribution systems (based on a pool of companies, or one major) in order to secure the value chain and therefore increase overall chance to reach value creation expectations.

You might have noticed that in this article, value is not only addressed from a financial standpoint but also from an organizational and strategic point of view, as sustainability involves the whole company: This is our vision!
Despite the need for an overall view of business, numbers convince easily: We will go further in details for step 4 later this month.

See you soon!

Revenue Management and its applications: Airlines

A brief context of the implementation
Revenue Management systems (also known as Yield Management) were first implemented at American Airlines and Delta Airlines about 30+ years ago. Robert Cross – now president at Revenue Analytics, and author of the famous Revenue Management, Hard-core tactics for market domination – implemented this system at Delta. Robert Crandall – retired CEO at AMR Corp. and founder of Sabre distribution system – implemented it at American Airlines.

At that time, airlines used to set prices per class of service and per season.

In the hospitality industry, the implementation of a Revenue Management system was an answer to the necessity to steer an entropic market, with unreachable and numerous customers: every flight and every route represented new markets, where revenue had to be maximized. Revenue Management systems enabled continuous growth of travelers, (who were booking tickets over the counter at that time) along with the development of global distribution systems (SABRE, and later Amadeus), and the very first strong information systems.

The first preoccupation of early adopters of Revenue Management systems was to face the growing competition and the crawling crisis. Long story short, marketing efforts to stop the fare war were not enough, and a backroad between supply chain management, marketing, and information systems was the creation of Revenue Management systems. Revenue Management systems aimed at controlling inventory and maximizing the price of each seat contingent on demand in a real time system. The primary goal was to repair the market. In addition to the fare war, the expansion of the low cost airline PeopleExpress forced the market to offer more competitive call fares, such as ”ultimate super savers” by American Airlines in 1985.

The way it works in the airline industry…
As you may understand, Revenue Management is a very sensitive topic within airlines, but some of the key features are common to most carriers (including both flag carriers and low cost carriers).

Basic principles: How a plane gets filled
The fares are mostly function of time and load factor of the aircraft. During the weekdays, the main goal is to separate business travelers from leisure ones. During weekends, it is the contrary, which affects significantly the perspective for revenue: the strategy aims at having less but more profitable customers during weekdays in order to reduce operational costs. Every flight / route combination (one origin and one destination) is managed as a new service, where profit – and consequently the load factor - must be maximized. The more filled-up a flight gets, the more expensive your ticket will be. Besides, airlines usually like to offer tickets with distinct characteristics: flexible, reimbursable and re-bookable with or without fee, or non-flexible (simply put, if you don’t use the ticket you lose it).

Assuming that bookings increase over time, as a linear function, here are two graphs representing the evolution of the fares function of number of bookings (and so function of advance booking):
fare curve airline
revenue management
fare curve airline study
From what we explained in the previous paragraph, fares should increase with time. However, praxis showed a real difference. The second graph is the relevant one: there you can assess the dynamic of Revenue Management and its interest for a corporation - adapting exactly the pricing to the market situation based on historical data.


Note that the charts presented above, represent an observed trend, and not precise data to be analyzed in details.

Fares and booking systems
To model pricing in their revenue management system, airlines use price brackets, called “booking classes”, which contain a reference fare, (i.e. the flexibility and availability during the weekdays). Each booking class can be opened or closed according to the aircraft load factor and the achievement of the profit objectives. Cheaper booking classes have limited inventory (at the bottom of the ladder), last seat availability classes are available as long as a seat is available in the aircraft (at the top of the ladder).
yield management fare table airline
Every airline has its own coding system for the reference fare (booking class + fare basis). Airlines also like to set low fares with more flexible reference fares for their corporate customers. This is a way to bias the market. This is what a travel agent can get in its global distribution system.

If you would like to have a better understanding on how Revenue Management systems work in a real life case, the MIT proposed a
simulation of an Airline Revenue Management.

…and in other businesses
We want this blog to be interactive, and our goal is to gather a community of beginners and insiders, trying to create inspirations for businesses. Therefore, any valuable input is much appreciated.
More specifically, we invite readers from any background to submit ideas of business sectors where Revenue Management principles could be applied.

Introduction - Companies should pay more attention to their top line

Dear Reader,

Thank you for passing by and visiting this blog! We would just like to share with you a quick introduction on our blog, its purpose and content.

We are two French students, Julien GUBIANI and Yoann PINET:
- Yoann is a MBA candidate at Pepperdine University (California): He has 2 years of experience in corporate finance and consulting, and is now focusing his career on consulting. 
- Julien just graduated from Rouen Business School's Master in Management (France): He his now consutling in the Revenue Management field with air management companies. He has 2 years of experience in business consulting. More particularly, Julien addressed yield management issues as intern at Carlson Wagonlit Travel for 7 months. 

Revenue Management is not a common topic in management science - at school or within corporations. It is widely associated with airlines companies and hotel chains. We have created this blog to cast Revenue Management in a different light 
It seems that many corporations are primarily focused on optimizing costs. Obiously, the outcomes of the financial crisis give a good example: companies' first move was to cut costs. Even in regular economic conditions, they are clearly communicating shareholders and third parties about the successful results of cost-cutting measures, rather than actions to maximize revenue (sensitive subject or lack of tactic to drive revenue? Maybe both…). 

In corporate communication (internal and external), the reporting of actions on revenue is conducted through the P&L, as well as through the very “unique” mission statement: “We commit on delivering the best value to our customers” - which at first sight is a widespread PR or sales speech. Taking a closer look at that kind of mission statement, we could see another explanation: delivering the best value to customers can also mean achieving a price and service combination that matches expectations with regard to the limited ressources available for sale. The hospitality industry (airlines, hotels…) has been applying this principle for 25 years, with the results we know: top airlines & low cost carriers operating profits are in the top 30 list, see the 2010 IATA report

The optimization of supply and demand, matching constraints of profitability and available inventory on a given market, is Revenue Management.

In this blog, after a more detailed explanation of Revenue Management objectives and methods; we will try to demonstrate that this discipline is at an early stage in terms of implementation, and that it can still be implemented (partially or fully) in many sectors.
