The Cowles Commission approach is reviewed and compared to the approaches of real business cycle (RBC) theorists and new Keynesian economists. It is argued that RBC models are not tested in a serious enough way and that the new Keynesian literature is not empirical enough for testing even to be...

This paper shows that nominal price rigidity can arise from a failure to coordinate price changes. If a firm's desired price is increasing in others' prices, then the gains to the firm from adjusting its price after a nominal shock are greater if others adjust. This "strategic complementarity"...

An otherwise conventional Keynesian macro model is modified to include inventories of final goods by (1) drawing a distinction between production and final sales, and (2) allowing for a negative effect of the level of inventories on production. Two models are presented: one in which the labor...

Can increased uncertainty about the future cause a contraction in output and its components? An identified uncertainty shock in the data causes significant declines in output, consumption, investment, and hours worked. Standard general-equilibrium models with flexible prices cannot reproduce...

The fact that most of the persistent declines in output since the Great Recession have parlayed into equivalent declines in measures of potential output is commonly interpreted as implying that output will not return to previous trends. Using a variety of estimates of potential output for the...

We consider bank panic models in which, depending on the configuration of fundamentals, there can be a positive probability of a bank panic. A crucial assumption in these models is that new equity cannot enter in a panic. We quantify the importance of this assumption by computing the minimal...

This paper uses the old-Keynesian representative agent model developed in Farmer (2010b) to answer two questions: 1) do increased government purchases crowd out private consumption? 2) do increased government purchases reduce unemployment? Farmer compared permanent tax financed expenditure paths...

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...

The Covid-19 crisis is an unusual and seemingly all-encompassing economic shock. On the one hand, it was unquestionably a negative demand shock that, for fixed prices and incomes, reduced household spending. On the other hand, it was also unquestionably a negative supply shock that reduced...

This Chartbook, which is a companion piece to Carmen M. Reinhart and Takeshi Tashiro (2013) "Crowding Out Redefined: The Role of Reserve Accumulation," focuses on nine Asian economies: China, India, Indonesia, Japan, Korea, Malaysia, Philippines, Singapore and Thailand. Like its predecessor...
