Ideas of Milton Friedman Positive economics is in principle independent of any particular ethical position or normative judgments … it deals with “what is,” not with “what ought to be.” The ultimate goal of a positive science is … a theory or hypothesis that yields valid and meaningful predictions about phenomena not yet observed … [T]heory is to be judged for its predictive power... The choice among alternative hypotheses equally consistent with the available evidence … [is] suggested by the criteria of “ simplicity ” and “ fruitfulness ”… within a given field of phenomena. Truly important and significant hypotheses will have “assumptions” that are wildly inaccurate descriptive representations of reality … A hypothesis is important if it “explains” much by little … [T]he relevant question is not whether [“assumptions”] are descriptively realistic … but whether they are sufficiently good approximations for the purpose in hand. Economics is a “dismal” science because it assumes man to be selfish and money-grubbing … it assumes markets to be perfect, competition to be pure, and commodities, labor, and capital to be homogeneous … [C]riticism of this type is largely beside the point unless supplemented by evidence that a [different] hypothesis yields better predictions.

More Ideas of Milton Friedman “ I never reached a judgment about monetary or fiscal policy because of my belief in free markets. ” A Monetary and Fiscal Framework for Economic Stability, AER 1948 –Eliminate private creation of money and discretionary control of M s by central bank  100% reserve banking –Base G on community’s desire, need, and willingness to pay for public services –A predetermined program of transfer payments –A progressive personal income tax system  Rely on automatic stabilizers … countercyclical action … [can] do too much as well as too little. (1951) The Case for Flexible Exchange Rates (1950) Instability of exchange rates is a symptom of instability in the underlying economic structure. Elimination of this symptom by administrative freezing cures none of the underlying difficulties and only makes adjustment to them more painful. Studies in the Quantity Theory of Money (1956) –The Quantity Theory of Money: A Restatement There is perhaps no other empirical relation in economics that has been observed to recur so uniformly under so wide a variety of circumstances as the relation between substantial changes over short periods in the stock of money and in prices … –Phillip Cagan, Monetary Dynamics of Hyperinflation Adaptive expectations and stable money demand –John Klein, German Money and Prices, l –Eugene Lerner, Inflation in the Confederacy, –Richard Seldon, Velocity in the United States

Yet More Ideas of Milton Friedman A Theory of the Consumption Function (1957) –“Errors” are in income, not in consumption  Permanent income hypothesis A Monetary History of the United States (1963) … inflation is always and everywhere a monetary phenomenon. …small events at times have large consequences. A liquidity crisis in a fractional reserve banking system is precisely the kind of event that can trigger – and often has triggered – a chain reaction. And economic collapse often has the character of a cumulative process. Let it go beyond a certain point, and it will tend for a time to gain strength from its own development as its effects spread and return to intensify the process of collapse. Because no great strength would be required to hold back the rock that starts a landslide, it does not follow that the landslide will not be of major proportions.

Paul Samuelson on Naïve Monetarism The pity increases for one who adopts a simple theory of positivism that exonerates a nominated theory (the quantity theory), even if its premises are unrealistic, so long as it seems to describe with approximate accuracy some facts. Particularly vulnerable is the scholar who tries to test competing theories by submitting them to simplistic linear regressions with no sophisticated calculations of Granger causality, cointegration, collinearities… The proof of the pudding is in the eating. There was a widespread myth of the 1970s… A new paradigm, monistic monetarism, gave a better fit. King Keynes is dead! Long live King Milton! [But] contemplate the true facts…In terms of accuracy…never did post-1950 monetarism score well.

Monetarism in Theory and Practice Theory: M  P and Y in short – run M  P in long - run Friedman’s restated quantity theory Expectations augmented Phillips Curve  Vertical long – run Phillips Curve  “Monetary mischief” Practice: oppose Keynesian activism Monetary vs. fiscal policy: what matters? Inherent stability vs. instability of enterprise economy Policy: Long – run vs. short – run focus Varying policy lags … “too much too late” »Steady money growth as automatic stabilizer
