Editing Keynesian economics (section)

===<span id=remedies>Remedies for unemployment</span>===
====<span id=monetary>Monetary remedies</span>====
An increase in the money supply, according to Keynes's theory, leads to a drop in the interest rate and an increase in the amount of investment that can be undertaken profitably, bringing with it an increase in total income.

====<span id=fiscal>Fiscal remedies</span>====
Keynes' name is associated with fiscal, rather than monetary, measures but they receive only passing (and often satirical) reference in the ''General Theory''. He mentions "increased public works" as an example of something that brings employment through the ''multiplier'',<ref>Chapter 10.</ref> but this is before he develops the relevant theory, and he does not follow up when he gets to the theory.

Later in the same chapter he tells us that:
<blockquote>Ancient Egypt was doubly fortunate, and doubtless owed to this its fabled wealth, in that it possessed two activities, namely, pyramid-building as well as the search for the precious metals, the fruits of which, since they could not serve the needs of man by being consumed, did not stale with abundance. The Middle Ages built cathedrals and sang dirges. Two pyramids, two masses for the dead, are twice as good as one; but not so two railways from London to York.</blockquote>
But again, he does not get back to his implied recommendation to engage in public works, even if not fully justified from their direct benefits, when he constructs the theory. On the contrary he later advises us that ...
<blockquote>... our final task might be to select those variables which can be deliberately controlled or managed by central authority in the kind of system in which we actually live ...<ref>Chapter 18.</ref></blockquote>
and this appears to look forward to a future publication rather than to a subsequent chapter of the ''General Theory''.
