That complacency, of course, vanished with the financial crisis and the Great Recession that followed. Modern research on rules and discretion has helped illuminate the tradeoffs inherent in a range of policy questions. I started a Phd in Economic History at Lund University, Sweden, in September 2015. This result offers the worst of both worlds—homes are destroyed by floodwater, and victims who ignored warnings are indemnified with taxpayer funds. Central banks are bureaucracies, and bureaucracies are not adept at processing new information and making changes to policies in response. Supplying excess liquidity to support growth that turns out to have been ephemeral would undermine the very good economic performance we have enjoyed. Read this paper for more:.
However, Keynesians find that output, unemployment, and prices can be stabilized in the short run by autonomous expenditures, including those by the government. The book attributed inflation to excess money supply generated by a central bank. Rules rely on past observations, but the economy and its institutions continually evolve. As I indicated to the Congress recently, however, the period of predictable velocity is too brief to justify restoring M2 to its role of earlier years, though clearly persistent outsized changes would get our attention. Thus, as the historic relationship between measured money supply and spending deteriorated, policymaking, seeing no alternative, turned more eclectic and discretionary. This increase in demand leads to higher prices, causing more inflation.

Discretionary policy may be inconsistent when it does not change the initial conditions that create a disturbance, or shortsighted when a policy requires lags to materialize. Having established the superiority of a rules-based approach, the study looks at the pros and cons of several popular proposed rules. Please do not remove this message until. Must It Be a Rule? They assume that central banks can appropriately pay attention simultaneously to developments in both output and inflation, provided their reactions occur in the context of a longer-run goal of price stability and that they recognize that activity is limited by the economy's sustainable potential. Further, sometimes higher inflation is a good thing because it stimulates spending.
Potential output and the natural rate of interest are only concepts in the mind of economists and they cannot be observed directly. What if there is a mistake? Rules Rather Than Discretion: The Inconsistency of Optimal Plans. If data on profits and prices are even approximately accurate, total consolidated corporate unit costs have, of necessity, been materially contained. Further, as commented by Milton Friedman who argued in favor of a rules-based approach, the dynamics of discretionary policy present a lag between observation and implementation. This certainty stimulates economic activity. History, however, is somewhat ambiguous on the issue of whether central banks can safely ignore asset markets, except as they affect product prices.
According to Kenneth Arrow, the world of uncertainty necessitates discretionary policies. Still, sensible policy does presuppose a conceptual framework, or implicit model, however incompletely specified, of how the economic system operates. For Simon, such a systemic policy appears paradoxical, as it would require an intelligent monetary system on the one hand, and credibility of rules on the other. The inflationary shocks of the 1970s and the financial crisis of the Great Recession are the two biggest events in this category. Increasing government spending, creating a budget deficit, and financing the shortfall through debt issuance are typical policy actions in an expansionary fiscal policy scenario.
These are the events that make expert discretionary policymaking invaluable. Remember that government revenue is based on collected taxes. Unfortunately, however, history is not an infallible guide to the future, and the levels of these two variables are currently under active debate. And no floodplain construction today means no need for flood relief tomorrow—a time-consistent outcome. When taxes equal government expenditures, the government has a balanced budget. Even more important than evolutionary changes, the big challenges to monetary policy come from shocks and surprises that rules cannot anticipate or prepare for. Taylor extended his policy rule to price and nominal income rules for the open economy under fixed versus flexible exchange rates.
If a rule is placed on the money supply, the monetarists look for a causal link between money and prices. People ignore these warnings and build anyway. Monetary policy, to a great extent, is the management of expectations between interest rates, the price of the use of money, and the total supply of money. He argued specifically for a rule restricting growth of the M2 measure of the money supply to 3 to 5 percent per year. Unlike many uncertain situations that have confronted monetary policy, there was little question that the appropriate central bank action was to ease policy significantly. Monetary policy that effectively manages the money supply helps ensure that prices for goods and services accurately reflect changes in supply or demand for those goods and services. Suppose, for example, a river that seldom floods rises above its banks and sweeps away homes.
For much of the 20th century, governments adopted discretionary policies to correct the business cycle. The definition of money and a stable velocity-of-circulation function are necessary for empirical investigation. Because policymakers cannot know everything about the economy at one time and their incentives as public actors remain the same as their incentives as private actors, establishing rules for their decision-making is preferable to prolonging the current discretion-based policymaking at the Fed. London: Institute for International Affairs, 1981. Congress regularly calls on the Fed Chairperson to explain its actions and part of Wall Street is always blaming the Fed for something it did or did not do. Journal of Political Economy 44 1 : 1 —30. The problem, in this scenario, is that not that the Fed is wrong per se.
