The big question was always, where do you get values for exogenous variables?

The first simulation takes the historical values of all exogenous variables as given.

The model has over 450 endogenous and nearly 500 exogenous variables.

This gives the latter as a function of the exogenous variables, if any.

That produced huge effects, but it was not an exogenous variable, introduced from outside.

Consequently, a number of exogenous variables were added to improve the estimates.

The main exogenous variables are the gross domestic product and population for each country or region.

Without an alien influence as an exogenous variable, the model always reached a crisis point about 2140.

In today's global business, however, multinational activities represent much more than just an exogenous variable.

New exogenous variables were a source of possible instability.

Consequently, they assert that economic models must take these typically exogenous variables into account.

Exogenous variables are sometimes known as parameters or constants.

Notice that these models may also use exogenous variables, mostly representing national aggregates.

But from the point of view of the model, the plague would have to be fed in as a new exogenous variable.

Note that both endogenous variables depend on the exogenous variable Z.

Exogenous variables are variables which are not determined by the system.

Accordingly, entrepreneurship is not (as it usually assumed) an exogenous variable with a life and importance of its own.

We have to introduce our own exogenous variables, things that we believe are possible logical components of the future.

In this type of analysis, the relative supply of labour is considered to be an exogenous variable (Johnson, 1997).

The variables that are solved inside the economic model. Exogenous variables:

However, in the social realm, life style is the exogenous variable, with prestige, status, and power dependent thereupon.

If we assume that demand is influenced not only by price, but also by an exogenous variable, Z.

Without further restrictions, the first equation is not identified because there is no excluded exogenous variable.

The controlling factor must be internal and not nutrients or sunlight acting as causal exogenous variables.

Critics of earlier development theories, mentioned above, point out that "ethnicity" and ethnic conflict cannot be treated as exogenous variables.
