Williams and Liebhold then suggest that generalist predators could act as exogenous factors

like state policy have a common influence on all regions in the agrarian sector.
Number of significant second-order models per 1000 time-series simulations for the Ricker model under 18 combinations of the parameters, r and [Psi], using two analyses (r = the intrinsic rate of population increase; [Psi] = the autoregressive parameter of the exogenous factor
Therefore, theory that emphasizes exogenous factors
like state policy as the only determinant of investment increases cannot explain such important increases in the scale of investment and production.
Thus, a population process without explicit second-lag effects can be represented as a second-order process through change in a random exogenous factor
. This clearly may affect the interpretation of delayed density dependence using a model such as Eq.
Even a weak 2Q result kept investors undeterred where exogenous factors
(FX Losses, losses on equities) overshadowed strong performance on core metrics.
There's not a lot of data ahead to add insight on the economic front, though exogenous factors

Reproductive patterns are regulated by both endogenous factors such as neuroendocrine cycles and genotype and exogenous factors
such as water temperature, food, salinity, and light (Gosling 2003, Lucas 2012).
Africa's problems have always been endogenous though exploited by exogenous factors
. Outsiders have always taken advantage of our internal weaknesses to dominate us," he said.
Exports depend on several endogenous and exogenous factors
. These include foreign market access including the size of key trading partners, their growth rates and trade barriers; the real exchange rate (nominal exchange rate plus relative price movements at home and abroad); and supply-side situation in the exporting country.
that are outside the scope of monetary policy may lead to transitory deviations from pre-announced target rates.
