Como intentaron los europeos mantener el control sobre sus colonias en Africa
​

Los europeos usaron todo tipo de métodos para mantener el control de sus colonials en África, tales como la intimidación a la población civil, las alianzas estratégicas con otras naciones europeas, la explotación laboral o esclavitud, y la negación de derechos civiles y económicos a las poblaciones nativas.

También usaron métodos más sutiles tales como la imposición del idioma, la educación de burocracias locales, y la promoción, hasta cierto punto, de una cultural europea en África.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
