  Path dependence - Wikipedia, the free encyclopedia
Path dependency theory was originally developed by economists to explain technology adoption processes and industry evolution.
Path dependence has primarily been used in comparative-historical analyses to analyze the development and persistence of institutions, whether they be social, political, or cultural.
This is akin to the concepts of lock-in or positive feedback derived from path dependence in economics.

The literature of path dependence may be understood to argue that these lock-ins and errors occur, even in a world characterized by voluntary decisions and individually maximizing behavior.
The claim for path dependence is that a minor or fleeting advantage or a seemingly inconsequential lead for some technology, product or standard can have important and irreversible influences on the ultimate market allocation of resources, even in a world characterized by voluntary decisions and individually maximizing behavior.
Third-degree path dependence is the only form of path dependence that conflicts with the neoclassical model of relentlessly rational behavior leading to efficient, and therefore predictable, outcomes.

Path dependence, lock-in and sub-optimal efficiencies are to be expected.
In political science path dependence is formalized recognition that decisions made in the past have a continuing influence on policy development.
But because of investment in catching capacity, because the ‘stakeholders’ were boat owners and cannery managers dependent upon the promised volumes of fish, and coastal communities dependent upon the cash flow from the fishery, government and regulators were ‘locked in’ to this particular approach to a fishing industry.

In traditional processual story based strategy titles, path dependency is probably one of the most often used variables that influences in-game technological development.
Basically, path dependency means that that technological change and innovation depends on its own past.
For example, designers can start with a base technological path that is defined by the geographic environment in which the scenario is going to be played out, the level of technological sophistication (probably something set by the back-story), and pre-defined parameters of the technological path (what innovations are available to the player).

Path dependence contends that decisions made in the past are likely to have long-term impacts on water systems by binding, limiting or postponing alternative options.
The argument for path dependence is that a minor or fleeting advantage or a seemingly inconsequential lead for some technology, product or standard can have important and irreversible influences on the ultimate market allocation of resources, even in a world characterized by voluntary decisions and individually maximizing behavior.
The path of institutional change is shaped by (1) the lock-in that comes from the symbiotic relationship between institutions and the organisations that have evolved as a consequence of the incentive structure provided by those institutions and (2) the feedback process by which human beings perceive and react to changes in the opportunity set.

 EH.R: Path dependency
First, it is well to remember that path dependence is part of a broad, growing literature that takes history seriously in social theory.
If correct, then path dependence is calling our attention to a limit of markets (not perhaps in the strict, Pareto sense a failure) in assuring the best technology ever gets invented, or sees the light of day.
The point of path dependence is, the way back (to B) is difficult, if not impossible, not because markets fail but because in a market sitatuion no rational actor would ever want to pay the costs of backtracking.

 Intelligible Differences
Both beliefs combine in the familiar idea of path dependency; but it is the predominance of the second which makes of that notion at once a shorthand expression for certain methodological convictions and the expression of a deep pessimism about the possibility of effective, deliberate action in the world.
It is, as you know, the world of path dependency; and the rapid diffusion of this set of ideas among economists in particular may be an indication that they have more in common with the moods of the average Joe than they themselves may suppose.
The surprise, to which we turn next, is that neither story supports the view of path dependency associate with it, and that the second, in particular, opens the way to a direct challenge to the fourth and apparently weightiest item on the list of possible causes of path dependence: cognitive self entrapment.

Theories II and I deal with the idea that the consequence that happens could not have been avoided or was not known at the time of the purchase, thus there is not an inefficiency.
Theory III on the other hand is a path dependency that deals with market inefficiency; the consequence was known but not avoided.

For civilizations that reside in river valleys or close to the ocean, the technological path could include maritime trade, the waterwheel, shipbuilding, and hydroelectricity.
For civilizations where population centers are widely dispersed, the path could include long distance trade, communication devices, and high-speed travel.
The pace and manifestation of this technological path would in turn be influenced and affected by a suite of other variables (like those discussed in this article).

In 1999-2000, three more speakers who dealt with wide-ranging topics related to the problem of path dependency, (i.e., the institutional constraints often ignored by transition economists as they conceptualize the development of market societies) were invited to Rice.
Recent research on the path of privatization in the 1990s in the former centralist planned economies of China, Eastern Europe and the former Soviet Union has emphasized the role of "path-dependency," or the historical constraints on the selection of privatization strategies.
Both the privatization and democratization reforms in these societies seem to follow a path constrained by a reverse logic of the way in which the institutions of the planned economies were set up in the 1950s.

A derivative is path-dependent if its payoff at exercise or maturity depends not only on the value of the underlying asset at the time, but also on some history of the underlying asset values.
An example of a path-dependent derivative would be a lookback option where the payoff at maturity or exercise depends on the maximum or minimum of the underlying asset price during the lifetime of the contract.
This is because if any of these outstanding securities are exercised during the lifetime of the CB we are valuing, we might expect the share price to drop to reflect the resultant dilution effect.

 Urban Sprawl as a Path Dependent Process - Questia Online Library
According to Michael Radzicki and John Sterman, "Path dependency is a characteristic of models that get locked into the particular dynamical path they initially 'choose' (usually by chance)" [Radzicki and Sterman 1994, 64].
Models are a useful means of simulating dynamic change and presenting the logical consequences of remaining on a particular path.
Path dependency is therefore another way of understanding economic change as a process of cumulative causation where the dominant feedback loops are self-reinforcing rather than self-correcting as they are in equilibrium models.

Well, one useful answer is an idea known as path dependency, i.e., once enough people follow a particular path in technology, that path becomes the standard one on which future technology and products depend.
Microsoft has, in effect, done the same thing, promoted a sharing of strategy to create an industry standard and to be sure, it's also marketed like mad, throwing its weight around monopoly-like, some would say illegally, to keep the competition at bay.
But for the present, path dependence can explain a lot about how and why the world of technology around us has taken the shape it has and why the better mousetrap doesn't necessarily prevail.
