This paper analyzes the causes and implications of recent financial crises. Financial crises in general lead to changes in both theory and practice of economics. The paper takes an historical overview. The global consensus of economic theory during the 20th century is discussed. The paper...

This paper provides an overview of the evolution of macroeconomic thought from 1936, the year John Maynard Keynes published his general theory of employment, interest and money to the year 2010. It explores the reasons for the extension of the business cycle during the postwar period. The paper...

This paper offers a reappraisal of the inflation-unemployment tradeoff, based on "frictional growth" describing the interplay between nominal frictions and money growth. When the money supply grows in the presence of price inertia (due to staggered wage contracts with time discounting), the...

We study the effects and historical contribution of monetary policy shocks to consumption and income inequality in the United States since 1980. Contractionary monetary policy actions systematically increase inequality in labor earnings, total income, consumption and total expenditures....

This study analyzes the emergence of secular stagnation as the consequence of a rise in the preference for liquidity. Such a rise is caused by a persistent set of pessimistic expectations. This study also investigates the effectiveness of a broad range of demand-management policies in dealing...

In this paper we argue that both statistics and economic theory-based evidence largely indicate the absence of long run relationships between the real output and the most relevant monetary indicator for the U.K. and the U.S short term interest rates. These findings are not only a full sample...

Conventional Phillips-curve models that are used to estimate the output gap detect a substantial decline in potential output due to the present crisis. Using a multivariate state space model, we show that this result does not hold if the long run role of excess liquidity (that we estimate...

We study the effects and historical contribution of monetary policy shocks to consumption and income inequality in the United States since 1980. Contractionary monetary policy actions systematically increase inequality in labor earnings, total income, consumption and total expenditures....

Recent empirical research found that the strong short-term relationship between monetary aggregates and US real output and inflation, as outlined in the classical study by M. Friedman and Schwartz, mostly disappeared since the early 1980s. In the light of the B. Friedman and Kuttner (1992)...

We study the cyclical properties of sales, regular price changes and average prices paid by consumers ("effective" prices) using data on prices and quantities sold for numerous retailers across many U.S. metropolitan areas. Inflation in the effective prices paid by consumers declines...
