This paper presents a model of the macroeconomy that reformulates what I take to be two important ideas from Keynes General Theory. The first is that there may be a continuum of steady state unemployment rates. The second is that beliefs select an equilibrium. I argue that search and matching...

This paper deals with the relationship between inflation targeting and exchange rates. I address three specific issues: first, I analyze the effectiveness of nominal exchange rates as shock absorbers in countries with inflation targeting. This issue is closely related to the magnitude of the...

Changes in both the macroeconomy and in macroeconomics suggest that the IS-LM-AS model is no longer the best baseline model of short-run fluctuations for teaching and policy analysis. This paper presents an alternative model that replaces the assumption that the central bank targets the money...

We propose an easy-to-use search friction in the goods markets in medium-sized New Keynesian models. This friction allows increases in measured productivity in response to increases in expenditures via higher search effort from households. As a result markups can become procyclical and labor...

This paper revisits and proposes a resolution to an empirical and theoretical controversy between Keynes and the "classics" (or monetarists). The controversy dates to Keynes's General Theory (1936)--most famously formalized in Hicks's (1937) classic Econometrica article, in which the IS-LM model...

Much of the new theory of macro-economics that has been built upon micro-economic models of imperfect information leads to conclusions which are surprisingly close in spirit to Keynes' original analysis. This paper summarizes the macro-economic implications of information-based models of...

This paper provides an outline of the historical development of Keynesian macroeconomics. It first argues that the business-cycle model of J.M. Keynes's General Theory featured analytical ingredients that were present in earlier writings and attained its theoretical precision only in...

This paper outlines a general set of principles for tax avoidance. Most of at least the common tax avoidance schemes can be reinterpreted as making use of one or more of these principles. Four such methods are described. In a perfect capital market, these methods would enable the astute taxpayer...

This paper develops a model of dual labor markets based on employers' need to motivate workers. In order to elicit effort from their workers, employers may find it optimal to pay more than the going wage. This changes fundamentally the character of labor markets. The modelis applied to a wide...
