Understanding EEPPSA Curves




A Self-Improvement, Self-Awareness, and Applied Game Theory Newsletter.

Helping you become more intuitive, effective, efficient, precise, productive, and financially independent through Gamer Thinking and Measuring Your Effectiveness, Efficiency, Precision, and Productivity


What is the meaning of life, and how can you use applied game theory, gamer psychology, and puzzle-solving  to not only survive but prosper in all your relationships.


Q. Lewis, I have heard you speak of EEPPSA (effectiveness, efficiency, precision, productivity, and self-awareness) as a measure of success. Is there a way to actually measure EEPPSA so that a person exploring self-improvement, and personal development know they are on the right track?

A. You are actually asking a number of related questions here concerning success, the creation of wealth, and EEPPSA in general. Many motivational leaders including Tony Robbins addresses some of these issues but not all of them. Here are the main points, questions, and areas of information addressed in this blog.

  • What are examples of self-development?
  • What do you mean by efficiency?
  • What do we mean by productivity?
  • What does self improvement mean?
  • What is the power efficiency?
  • What is productivity and its importance?
  • What is the efficiency formula?
  • What is productivity example?
  • What is productivity and types of productivity?
  • What are examples of efficiency?
  • How can we improve our self-development?




There is something we use in HAGT (Harrison’s Applied Game Theory) which we call an EEPPSA Curve. Also known in the business world as a production–possibility frontier (PPF) or production–possibility frontier curve (PPC), an EEPPSA Curve is a graph of the frequencies of different values of a variable in a statistical distribution. Such a graph shows various combinations of the amounts of two variables (usually goods and services) that can be produced within the given resources and technology. Described another way, an EEPPSA Curve is a graphical representation showing all the possible options of output for two products that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time.


An EEPPSA Curve illustrates several economic concepts, such as allocative efficiency, economies of scale, opportunity cost (or marginal rate of transformation), productive efficiency, and scarcity of resources (the fundamental economic problem that all societies face). This type of illustration is invaluable to an individual or organization seeking to maximize EEPPSA (effectiveness, efficiency, precision, productivity, and self- awareness.)


This trade-off is usually considered for an economy but also applies to each individual household, and economic organization. One good can only be produced by diverting resources from other goods, and so by producing less of them.




Graphically bounding – illustrating a data point within a specific paradigm the EEPPSA Curve shows the maximum possible production level of one commodity for any given production level of the other, given the existing state of technology. By doing so, it defines productive efficiency in the context of that production set: a point on the frontier indicates efficient use of the available inputs (for example  “A” efficiency, “B” effectiveness, “C” productivity, “D” precision,”E” self-awareness, in the graph). To create standards for success a point beneath the curve (such as A) may be said to indicate indicates inefficiency, and a point beyond the curve (such as “F”) might indicate improbability or impossibility.

EEPPSA Curves are normally drawn as bulging upwards or outwards from the origin (“concave” when viewed from the origin), but they can be represented as bulging downward (inwards) or linear (straight), depending on a number of assumptions.

An outward shift of an EEPPSA Curve results from growth of the availability of inputs, such as physical capital or labor, or from technological progress in knowledge of how to transform inputs into outputs. Such a shift reflects, for instance, economic growth of an economy already operating at its full productivity (on the An EEPPSA Curve), which means that more of both outputs can now be produced during the specified period of time without sacrificing the output of either good. Conversely, the PPF will shift inward if the labor force shrinks, the supply of raw materials is depleted, or a natural disaster decreases the stock of physical capital.


However, most economic contractions reflect not that less can be produced but that the economy has started operating below the frontier, as typically, both labor and physical capital are underemployed, remaining therefore idle as has happened during the Covid-19 Pandemic of 2020. This underemployment is addressed in HAGT research related to wasted or stored resources.

In microeconomics, the behavior of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms is explored. An EEPPSA Curve can show the options open to an individual, household, or organization in the best-case scenario. By definition, each point on the curve is individually productive, precise, efficient, and effective but, given the nature of market demand, some points will be more profitable than others. By market demand I mean the sum of the individual demand for a product or service from buyers in the market. If more buyers enter the market and they have the ability to pay for items on sale, then market demand at each price level will rise. Equilibrium for any organization will be the combination of outputs on the EEPPSA Curve that is most profitable.

Let’s explore these ideas from the perspective of macroeconomics – the study of how an overall economy—the market systems that operate on a large scale—behaves. From this perspective, one can still be highly productive even with deficiencies in some aspects of  EEPPSA.

This is because in macroeconomics one must explore and take into consideration economy-wide phenomena such as inflation, recession,  price levels, rate of economic growth, national income, gross domestic product (GDP), and changes in unemployment. From this perspective, the EEPPSA Curve can  illustrate the production possibilities available to a nation, organization, or an individual’s economic behavior during a given period of time. This illustration would also take into account broad categories of output such as would be described in 24 Core Resources (TCR) that are central to the implementation of HAGT (Harrison’s Applied Game Theory).  Some of the TCR are time, space, information, influence, and cash.

There is no way to perfectly balance all of the elements in EEPPSA however, economic behavior may achieve productive efficiency without necessarily being allocatively efficient. Market failure is an economic situation defined by an inefficient distribution of goods and services in the free market. Such a state leaves plenty of room for productivity even when there is inefficiency, ineffectiveness, and lack of precision.  In HAGT it is easy to see that in market failure, the individual incentives for rational behavior do not necessarily lead to rational outcomes for the group.

In many business environments, there are certain constraints that cannot be isolated though the ripple effect from their very existence can be measured.  For example, three common constraints are;

  1. Imperfect competition – Competition for limited resources among individual or group that have limited information about the resources or intentions of the other competitors
  2. Externalities – This has to do with external elements that cannot be measured, easily predicted or controlled, even if known.
  3. Some institutions of social decision-making such as government and tradition. Here you are dealing with a combination of corruption, incompetence, and political expediency.


These three elements, either individually or in combination may lead to the wrong combination of goods being produced (hence the wrong mix of resources being allocated between producing the two goods) compared to what consumers would prefer, given what is feasible on the EEPPSA Curve.

So in conclusion, an EEPPSA Curve which can be done as simply as creating and prioritizing a shopping list, integrates gamer psychology, wasted resources, ideas such as ripple effect and Black Swan Events, measurements for effectiveness, efficiency, precision, productivity, and self-awareness, and the distinction between want and need.
