入力効率 II

Imagine two farmers—one growing apples and the other oranges. They share the same fixed resources: labor and capital. The challenge lies in efficiently allocating these inputs to maximize total output. 

To visualize this, we use an Edgeworth box, which represents all possible ways to distribute labor and capital between the two farmers. 

Now, consider Point F, an initial allocation of inputs. At this point, both farmers’ isoquants intersect, but they also enclose an area. 

Any input combination inside this area allows at least one farmer to increase output without reducing the other farmer’s output. Since reallocation can improve efficiency for at least one farmer, F is not Pareto-efficient.

Now, look at Point G, where the farmers’ isoquants are tangent. 

At this point, there is no way to reallocate inputs and increase one farmer’s production without reducing the other’s output. Point G appears to be a Pareto-efficient allocation of inputs.
