Document Summary

Lectures 3 and 4 the economic problem. Why does food cost much more today than it did a few years ago: we now use part of our corn crop to produce ethanol (a biofuel substitute for gasoline) What are the consequences of doing this: droughts have decreased global grain production. We can use an economic model the production possibilities frontier to learn why ethanol production and drought have increased the cost of producing food. We canals use this to study how we can expand our production possibilities, how we gain by trading, and why social institutions have evolved. The production possibilities frontier (ppf) is the boundary between those combinations of goods and services that can be produced and those that cannot. To illustrate ppf, we focus of 2 goods as a time and hold the quantities of all other goods and services constant.
