Evidence from a broad panel of countries shows little overall relation between income inequality and rates of growth and investment. However, for growth, higher inequality tends to retard growth in poor countries and encourage growth in richer places. The Kuznets curve-whereby inequality first...

The market for ski runs or amusement rides often features lump-sum admission tickets with no explicit price per ride. Therefore, the equation of the demand for rides to the supply involves queues, which are systematically longer during peak periods, such as weekends. Moreover, the prices of...

Previous models of rules versus discretion are extended to include uncertainty about the policymaker's "type." When people observe low inflation, they raise the possibility that the policymaker is committed to low inflation (type 1). This enhancement of reputation gives the uncommitted...

Under a discretionary regime the monetary authority makes no commitments about future money and prices. Then, if surprise inflation conveys economic benefits and if people form expectations rationally, it turns out that the equilibrium involves high and variable monetary growth and inflation....

In a discretionary regime the monetary authority can print more money and create more inflation than people expect. But, although these inflation surprises can have some benefits, they cannot arise systematically in equilibrium when people understand the policymaker's incentives and form their...

Inflationary finance involves first, the tax on cash balances from expected inflation, and second, a capital levy from unexpected inflation. From the standpoint of minimizing distortions, these capital levies are attractive, ex post, to the policymaker. In a full equilibrium two conditions hold:...

Natural-rate models suggest that the systematic parts of monetary policy will not have important consequences for the business cycle. Nevertheless, we often observe high and variable rates of monetary growth, and a tendency for monetary authorities to pursue countercyclical policies. This...

Some previous analyses have suggested that the smoothing of tax rates over time would be a desirable guide for public debt management. One implication of this viewpoint is that future changes in tax rates would be unpredictable based on current information. This proposition is tested by...

This paper summarizes the theoretical role of intertemporal substitution variables in the "new classical macroeconomics." An important implication is that positive monetary shocks tend to raise expected real returns that are calculated from the usual partial information set, but tend to lower...

An important "empirical regularity" is the strong positive effect of money shocks on output and employment. One strand of business cycle theory relates this finding to temporary confusions between absolute and relative price changes. These models predict positive output effects of unperceived...
