The purpose of the Brightline simulation
is to create a simplified, accurate model of a market economy in which
businesses compete against each other for a fixed pool of consumers.
Brightline currently models five companies that can be customized by the
user. Additionally, the shareowners (owners) of one of the five
companies are given the potential to become actively involved in running
the company, should the company's performance fall below their
expectations. The company assigned to have potentially active
shareholders will be called the "Focus" company.
Scope
The Brightline simulation encompasses
five companies from any given industry competing against each other for
a fixed pool of consumers. All parameters in the simulation are created
to operate on a random basis. The user then adds certain
"influences" to the basic random nature of the program to
entice the companies and consumers to act in a manner consistent with a
certain market. The time span for the market competition can be
determined by the user, but ten to fifteen years is suggested for
purposes of simulating the long term investing typically used by
institutional investors.
The five companies must compete in the
presence of potential government regulation and shareowner
"moderation" of their externalization practices. The fixed
pool of consumers represents the total market for the industry. The
fraction of the total customer pool using a given company as its
supplier therefore represents that company's market share in the
industry. Highlights of the simulation are described below:
Principles of Customer Movement:
Consumers, or customers, are directly correlated to earnings in
Brightline. Companies therefore compete to gain and retain the largest
customer base possible. Consumers are attracted to companies with the
lowest price product, also known as the best value supplier. Companies
can only make their product more attractive by increasing their
externalization and, therefore, lowering the price of their product.
In the Brightline simulation, customers will remain with their current
supplier until they notice a lower price supplier. Once
"seen", through a survey of the market, they will consider
moving to the new supplier according to predefined Brand Loyalty
levels.
Government and Shareowner
Intervention: When a company is externalizing beyond the
government-defined legal limit, the government can impose a fine and
bring the company's externalization back down below the legal limit
for a set amount of time. Fining therefore makes the illegally
operating company less competitive for a set amount of time.
Shareholders of the Focus company have the potential to become active
managers in their company, should two conditions be met: 1) their
company's market share must fall below a specified level, and 2) the
company must be externalizing beyond the legal limit. Once activated,
the Focus company shareholders prevent their company from
externalizing over the legal limit for the remainder of the
simulation.
Statistical Analysis of Brightline
A statistical analysis of the Brightline
program was performed to ensure the integrity and non-biased performance
of the program. To demonstrate the validity of simulation results in
Brightline, we began by analyzing the functioning of all input
parameters for the simulation independently and in relation to each
other. We began by demonstrating that, with all companies set to
function according to the same rules, the basic random movement of
consumers does function properly. We then determined that with each
company set, one at a time, to have a differential market advantage or
disadvantage, the other four companies would win randomly. Such tests
were conducted for each parameter that can be set by the user.
Extensive efforts were taken to ensure
that the Focus company was modeled in an impartial, unbiased way with
the exception of the intended functions of the active shareowners.
Indeed, testing demonstrated that the only additional inputs into the
Focus company are active shareowner effects.
We have begun testing to determine the
potential advantages of Eco-friendly companies and of active shareholder
intervention in long-term investment demonstrated by most institutional
investors. Analyses presented in this book, while still in their early
stages, clearly demonstrate these proposed advantages. We have seen
that, in the short-term, the most aggressive, externalizing and
Eco-unfriendly companies gain a market advantage. However, we can
reliably demonstrate that, with a 12-year investment horizon, a discount
rate of 6%, and all companies operating with the same management
strategy, the Focus company "wins" the market 17 out of 20
times (p<0.01).
Oil Industry Analysis
For our Brightline analysis of the oil
industry, we were fortunate to have the expert input of Dr. Martin
Whittaker, principal author of the 2000 Global Integrated Oil and Gas
Survey for Innovest. Dr. Whittaker took the lead role in defining how to
accurately represent the oil industry in the Brightline parameters. With
Dr. Whittaker's assistance, we were able to pit British Petroleum,
ExxonMobil, Total Fina, Imperial Oil, and Occidental against each other
for 12 years of simulated industry competition. Detailed and described
below are explanations of the Brightline parameters used as inputs in
this simulation.
Interest rate used for discounting:
Because of the 12-year time span of the simulation, we needed to
provide the asset managers with a consistent language with which to
evaluate and justify alternatives. We applied a 6% discount rate to
all earnings to account for inflation.
Run time: In this analysis, we
sought to simulate the long-term investing of most institutional
investors. We chose 12 years in order to represent investments longer
then the average tenure of senior executives, and yet be short enough
to be realistic in terms of projection.
(Cycle length): Although not a
parameter to be set in Brightline, it merits description here. Each
year in a Brightline simulation is broken down into 24 two-week cycles
(for a total of 288 cycles). In the simulation, customers, companies
and shareholders are given the option to make decisions and changes in
their business once every cycle. This two-week time span for a cycle
is intended to be short enough to allow consumers and customers to
react quickly to a changing environment, yet be long enough to
stabilize the potentially frenetic movement of customers allowed by
the speed of computer modeling.
Customer Brand Loyalty: In every
industry there is a notion of loyalty to the brand, or reluctance to
change suppliers for whatever reasons. In the oil industry, there are
two main types of customers: industrial customers (large corporations)
and customers who pay at the pump. Brand loyalty at the pump tends to
be low, as customers can willingly and easily, say, drive a block
further to buy gas at 2 cents less per gallon. We chose a 30% brand
loyalty for this portion of the market. Industrial customers are more
reluctant or unable to change suppliers than individuals. We estimated
80% brand loyalty for them. We then estimated that 2/3 of industry
revenues are ultimately due to individuals and 1/3 to industrial
customers. Using these numbers to average the loyalty, we arrived at a
60% overall brand loyalty which we used in the simulation.
Shareholder Reactivity:
Shareholder reactivity determines the likelihood that shareholders of
the Focus company will become "angry", and thus actively
involved in the management of a company, should certain conditions in
the Shareholder Anger Mode (described below) be met. This parameter
was not used in these analyses because, in the baseline simulation, no
shareholders were allowed to become actively involved, and in the
Focus company simulations, shareholders were set to be active from the
start.
Government Vigilance: Different
industries are more or less scrutinized by regulators, public interest
groups, and the general public eye. The Government Vigilance parameter
is intended to represent this scrutiny that keeps companies in an
industry from externalizing their costs beyond reason. In Brightline,
this parameter functions by determining the probability that the
government will fine a company if it has exceeded the legal limit. We
decided that a 60% probability of fining, in each cycle, would best
represent the world environment within which the oil industry
operates.
Vigilance Mode: This parameter
determines how the government selects a company to fine, should it
choose to fine one in a given cycle. We have used what we call the
"weighted-exceed mode". In this mode, one company among
those that have exceeded the Legal Externalization Limit (described
below) is selected to be fined at a probability proportional to its
externalization over the legal limit in that cycle. Using this
setting, the company that is operating most illegally has the highest
probability of being fined, but all illegally operating companies are
vulnerable.
Brightline: Brightline is a
parameter which represents the "operating freedom" that a
new industry enjoys before they externalize their costs on the world
to an excessive level. It is in essence a period of time when
companies are operating within reasonable bounds on their own accord,
and are thus not moderated by the government or shareholders. In the
Brightline simulator, this parameter functions by allowing a set
"pool" of total externalization that is allowed to an
industry before the government is activated to control externalization
via fining. Because the oil industry is quite mature and well
monitored, we did not use this parameter in our simulation.
Legal Externalization Limit:
This parameter is used to set the total "units" of
externalization that are allowed for a given company before they risk
fining. Although it will be described in more detail below (in
Management Aggressiveness), suffice it to say that a unit of
externalization is equal to a unit of competitiveness. The more a
company externalizes its costs, the lower the price of its product.
However, externalizing costs are placed on society (for example,
higher toxic gas emissions due to outdated equipment), and society
will only absorb a finite amount of "waste". This parameter
defines that limit which society (the government) determines is
allowable.
Cycle shareowners may become active:
This parameter allows us to keep shareowners of the Focus company from
becoming active shareholders for a specified amount of time. For our
baseline analysis, where no company was allowed to have active
shareholders, we set this to the 289th cycle (after the simulation had
already ended), to prevent shareholders from activating. For our
analyses with different Focus companies, we set all shareowners to be
active from the beginning, so as to show the current potential of
active shareholders.
Number of votes needed for
shareowners to become active: Brightline assumes that there are 5
significant shareowners in each company. If the company is a Focus
company, their shareholders have the potential to become active,
should the performance of a company fall below defined standards
(established in Shareholder Anger Mode, below). This parameter defines
the number of votes, out of 5, needed to activate the shareowners and
force the company into compliance with the Legal Externalization
Limit. This parameter was not needed in our analyses.
Supplier Selection Mode: This
parameter determines how customers potentially choose a new supplier
(company) for their services. We used what we call a "random
mode". Using this mode, in each cycle, customers will look at one
other company, chosen at random, as a potential supplier. If the price
of their product is lower, and their Brand Loyalty allows, they will
move to the new company. If the other company's price is higher, they
will stay with their current company. Consumers therefore do not
survey the whole market place every two weeks for a new supplier. Use
of this mode in particular reflects Brightline's roots as an
agent-based, complexity theory model. A former member of the SWARM
programming team at the Santa Fe Institute created the core simulation
classes used in Brightline. Experimentation with SWARM which suggests
this approach to be more realistic than a completely random mode.
Shareholder Anger Mode: This
parameter sets the conditions that make the shareholders angry, thus
involving them in the running of their company. We used a mode that
causes the shareholders to become angry if their company's share price
falls below ½ of the market leader's share price.
Penalty Hold Time: This
parameter determines how long the effect of a fine imposed on a
company will last (fining will be described in more detail below in
Constraint Level). We estimated that in the oil industry, 6 months
would best represent the real world. This estimation is based on
observations that results even as tragic as the Exxon Valdez incident
are real, but not long lasting in the public market.
Constraint Mode: This parameter
gives a number of options for how a company is penalized when they are
fined. We selected a mode (mode 4) that holds the company's
externalization at a pre-defined level (to be defined in Constraint
Level, below).
Constraint Level: This parameter
defines the externalization limit at which a company is held for the
duration of the Penalty Hold Time if they are fined. This parameter is
only used if Constraint Mode is set to 4. We estimated that in the oil
industry, a 25% reduction in competitiveness would be most
appropriate. This estimate is based on observations that companies can
be hit fairly hard in the short term for certain acts. Take for
example Shell attempting to dump the Brent Spar platform in the North
Sea. Although this is not illegal, Shell lost 20% of its market share
in Germany in one week. We set this parameter to 3, or 25% below the
legal limit of 4.
Company Management Aggressiveness:
This parameter is the crux of the oil industry analysis, and the data
for which we are most indebted to Innovest. This parameter sets the
willingness of the management of each of the 5 companies to
externalize their costs. Recall that externalizing costs makes a
company more competitive in price, but unloads the company's internal
burdens on society. Therefore, the more aggressive a company, the more
they unload their costs on society. We used the Innovest EcoValue 21
scores from their 2000 Global Integrated Oil and Gas Survey. We picked
our 5 companies based on their international presence and their broad
range of EcoValue scores. Dr. Whittaker was kind enough to provide us
with preliminary scores before the actual publication was released.
EcoValue scores go from best to worst as follows: AAA, AA, A, BBB, BB,
B, CCC. BP received an AAA, ExxonMobil an A, Total Fina a BBB,
Imperial a B, and Occidental a CCC. To these scores we attached the
following Management Aggressiveness numbers (significance to be
explained later). BP was a 20, ExxonMobil a 16, Total Fina a 14,
Imperial a 12, and Occidental an 8. These numbers determine the
likelihood that a company will increase their externalization in a
given cycle. A 20 means that there is a 1 in 20 chance in each cycle
that a company will increase externalization. An 8 means that there is
a 1 in 8 chance (more likely) that they will increase, and so on in
between.
The results presented in the main text of
the book use the Brightline settings we have described above. The
Brightline simulator and the parameter file used for the baseline Oil
Industry analysis can be seen at http://www.ragm.com/brightline/index.html.
The version currently available online is slightly older than the one we
have used here. However, Brightline is a work-in-progress and new
versions will be updated regularly. Indeed, we encourage any interested
parties to use Brightline and give us feedback on the program. We
consider Brightline to be an ongoing project and value users
suggestions.
