SAVING LINE: A graphical depiction of the relation between household saving and household disposable income. The slope of this line is positive, greater than zero, less than one, and goes by the name marginal propensity to save. The vertical intercept of the saving line is autonomous saving. The saving and investment, or leakage and injection, analysis used in Keynesian economics begins with the saving line. Because consumption is the difference between disposable income and saving, the consumption line is a complementary relation to the saving line.

Economic Science
In this lesson you'll see why and how the scientific method is a process of discovery. You'll see that it's a process of building theories to explain the workings of the world (the economy) by proposing then testing hypotheses. The five units making up this lesson will guide you through the basics of the scientific method and how it's used in the study of economics. - The first unit introduces the scientific method, especially its' four key components -- theories, principles, hypothesis, and data.
- The second unit then takes a closer look at theories, including the central role played by abstraction.
- In the third unit, we will focus on the process of verification -- how and why hypothesized relationships about the workings of the economy are compared with actual data.
- We then turn out attention to a simple example of how the scientific method is used to test a hypothesized relation between course grades and where students are seated in a classroom.
- The fifth and final unit in this lesson examines the role that cause and effect plays in the scientific method and economic science.

BALANCE OF TRADE SURPLUS The positive difference of the value of goods and services exported out of a country less the value of goods and services imported into the country. A balance of trade surplus is the official term for positive net exports that occurs when exports exceed imports. A balance of trade surplus is also termed a "favorable" balance of trade because it results in a net inflow of monetary payments into the domestic economic from the foreign sector, which tends to be beneficial to a country. The alternative is a balance of trade deficit in which imports exceed exports.
