Which investment model best fits firm-level data? To answer this question we estimate alternative models using Compustat data. Surprisingly, the two best-performing specifications are based on Hayashi's (1982) model. This model's foremost implication, that Q is a sufficient statistic for...

We examine the dynamics of US output and inflation using a structural time varying coefficient VAR. We show that there are changes in the volatility of both variables and in the persistence of inflation. Technology shocks explain changes in output volatility, while a combination of technology,...

We examine monetary policy in the euro area from both theoretical and empirical perspectives. We discuss what theory tells us the strategy of Central banks should be and contrasts it with the one employed by the ECB. We review accomplishments (and failures) of monetary policy in the euro area...

The paper shows how prolonged price inertia can arise in a macroeconomic system in which there are temporary price rigidities as well as production lags in the use of intermediate goods. In this context, changes in product demand -- generated, say, by changes in the money supply -- have...

We study the mechanics of transmission of fiscal shocks to labour markets. We characterize a set of robust implications following government consumption, investment and employment shocks in a RBC and a New-Keynesian model and use part of them to identify shocks in the data. In line with the...

After a brief review of classical, Keynesian, New Classical and New Keynesian theories of macroeconomic policy, we assess whether New Keynesian Economics captures the quintessential features stressed by JM Keynes. Particular attention is paid to Keynesian features omitted in New Keynesian...

We examine the dynamics of output growth and inflation in the US, Euro area and UK using a structural time varying coefficient VAR. There are important similarities in structural inflation dynamics across countries; output growth dynamics differ. Swings in the magnitude of inflation and output...

Investment in inventories is known to be important for observed changes in GDP. However, inventory investment and the possibility that firms may fail to sell all goods are typically ignored in business cycle models. Using US data, the ability to sell is shown to be strongly procyclical. By...

We compare the output and unemployment effects of fiscal adjustments in different types of government outlays in the US, Canada, Japan, and the UK. We identify shocks in government consumption, investment, vacancies and government wages in a SVAR using sign restrictions extracted from a...

This paper models Chinese inflation using an output gap Phillips curve. Inflation modelling for the world’s sixth largest economy is a still under-researched topic. We estimate a partially forward-looking Phillips curve as well as traditional backward-looking Phillips curves. Using quarterly...
