The shift of the frontier from A to B was most likely caused by which of the following?

A. technological improvement in the production of batteries
B. more labour available in the economy
C. a general technological breakthrough
D. more capital available in the economy

The shift of the frontier from A to B was most likely caused by which of the following?A. technological improvement in the production of batteriesB. more labour available in the economyC. a general technological breakthroughD. more capital available
A
这是电池和面包圈两商品的边际效益图
由A曲线变成B曲线后,单位面包圈能换取更多的电池了,说明电池价格降低
而电池生产技术的提高能使电池生产成本降低,进而使电池价格降低
因此选A

A 电池生产的技术进步

读图可知,这是“电池”和“面包圈”的生产曲线。

首先把握曲线与坐标轴的交点(极端情形),可以得到两个结论:
1、全部生产电池时,A到B表示电池的生产量增加
2、全部生产面包圈时,A到B表示面包圈的生产量没有变化

所以可知这是一个部分的生产资料或技术增长。

BCD选项,无论劳动力要...

A 电池生产的技术进步

读图可知,这是“电池”和“面包圈”的生产曲线。

首先把握曲线与坐标轴的交点(极端情形),可以得到两个结论:
1、全部生产电池时,A到B表示电池的生产量增加
2、全部生产面包圈时,A到B表示面包圈的生产量没有变化

所以可知这是一个部分的生产资料或技术增长。

BCD选项,无论劳动力要素、资本要素或者技术要素整体增加,都会带来两种产品的产量增加,所以不符合结论二的情形。排除之。
