Recent progress in artificial intelligence (AI) - a general purpose technology affecting many industries - has been focused on advances in machine learning, which we recast as a quality-adjusted drop in the price of prediction. How will this sharp drop in price impact society? Policy will...

Over the past three decades, a large amount of research has attempted to identify the determinants of the natural rate of unemployment. It is this body of work we assess in this paper. We reach two main conclusions. First, there has been considerable theoretical progress over the past 30 years....

This paper begins by identifying nominal price stickiness as the logical basis for the Keynesian or activist point of view concerning demand management policy. It then characterizes two alternative approaches to policy analysis that have been adopted by adherents of the Keynesian position, the...

Most governments are mandated to maintain their economies at full employment. We propose that the best marker of full employment is the efficient unemployment rate, u*. We define u* as the unemployment rate that minimizes the nonproductive use of labor--both jobseeking and recruiting. The...

I show that a determinate, finite price level can be achieved in an economy with no monetary frictions, and no commodity standard or other explicit redemption commitment. I make one small modification to a standard cash in advance model: I reopen the security market at the end of the day. With...

The effects on ex ante optima of a lag in seeing monetary realizations are studied using a matching model of money. The main new ingredient in the model is meetings in which producers have more information than consumers. A consequence is that increases in the amount of money that occur with...

Both academic thinking about monetary economics and the practice of monetary policy have changed dramatically since 1971-1973, when the rational expectations revolution was beginning and the Bretton Woods system was crumbling. The present paper considers whether the various changes that have...

In the absence of monetary superneutrality, inflation affects capital accumulation and the demand for real balances. This paper derives the combination of monetary and lump-sum fiscal policy which maximizes the sum of discounted utilities of representative consumers in present and future...

This paper demonstrates that if current shocks are observed instantaneously, output can be stabilized perfectly for completely general supply disturbances, using simple monetary rules based only on: (i) the current shock, (ii) the previous forecast of the current shock, (iii) the forecast for...

This paper examines the interaction between the financial and real sectors of the economy within the framework of a stochastic, rational expectation model that distinguishes between inside and outside money. The model also can be used to study the impact of variations in the degree of...
