Inefficiency inside the PPF curve means that resources are not being fully utilized in the economy. This could be due to factors such as unemployment or underutilization of technology, resulting in less than optimal production levels. Inefficiency inside the PPF curve indicates that it is possible to produce more of one good without sacrificing the production of another.
Operating at an inefficient point, i.e. inside the PPF and not on the edge or line of the PPF
You must mean PPF? PPF: Production Possibilities Frontier.
The PPF graph is a bowed out curve. The x-axis being quantity produced of one product/service and the y-axis being another quantity produced of a product/service. Any point on the curve is productive efficiency. Outside of the curve is unattainable and inside of the curve is inefficient.
Production Possibility Curve this is an image of a ppf/ ppc
An economy can be producing on the PPF curve only in theory. In reality, economies constantly struggle to reach an optimal production capacity.
When there are diminishing marginal returns to factors of production, the PPF is "bowed out" from the origin.
The production possibility curve is not always linear, in fact, it is usually concave down (bowed-in). The shape of the curve depends on the substutability of the goods described by the curve in the question. When goods are perfectly substitutable in production, the PPP (or PPF) is linear.
An inrease in the retirement age would effectively increase a country's labor supply, shifting the production possibilities curve right.
A PPF is the locus of points such that all the economy's resources are used to its fullest potential. A PPF is concave to the origin because of the increasing opportunity cost to produce an additional unit of x (on the horizontal axes). A point inside the PPF is attainable because (1) there may be no full employment or (2) inspite of full employment they are used to less potential. On the contrary a point outside the PPF is not attainable because the PPF itself is the locus of the maximum attainable output given resources, the PPF may however expand due to increase in resources or their efficiency.
The PPF is bowed outwards (concave to the origin) as tradeoffs between the production of any two goods are constant.
why PPF in economics is negatively sloped
PPF - company - was created in 1991.
