This note critically evaluates the New Classical Macroeconomics from a Marshallian perspective. Revisiting the famous Keynes-Tinbergen controversy, it is argued that Keynes' criticism comprises the "Lucas critique," and that it is misleading to label this a critique of Keynesian economics. The...

During the pandemic, African banks rebalanced their portfolio towards sovereign assets, and crowding out of credit to private sector intensified. Policy support, however, averted a credit crunch. The increase in public debt across Africa due to the COVID-19 crisis intensified crowding out of...

We identify measures of shocks to total factor productivity and preferences from two real business cycle models and subject them to Granger causality tests to see whether they can be considered exogenous to other plausible sources of the German business cycle in the mid nineteen seventies and...

We consider the cyclical properties of the German economy prior and after reunification in 1990 from the perspective of a real business cycle model. The model provides the framework for the selection and consistent measurement of the variables whose time series properties characterize the cycle....

This paper shows that adjustment costs modelled as firing costs of moderate size go a long way in explaining the variability and counter-cyclicality of the labour share at the firm and aggregate level. Firing costs cause firms to hire less in recessions and hire less in booms causing wage costs...

We take as a starting point the existence of a joint distribution implied by different dynamic stochastic general equilibrium (DSGE) models, all of which are potentially misspecified. Our objective is to compare "true" joint distributions with ones generated by given DSGEs. This is accomplished...

Weakening bargaining power of unions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This paper documents and explains changes in income volatility. Using a theoretical framework which builds distribution risk into a real business cycle...

This paper studies the role of the German economy for the existence of the so called European business cycle, a term referring to the regularly observed synchronization of the national business cycles in Europe. Using a three-country general equilibrium model, we are able to simulate impulse...

We identify measures of shocks to total factor productivity and preferences from two real business cycle models and subject them to Granger causality tests to see whether they can be considered exogenous to other plausible sources of the German business cycle. For the period 60.i to 89.iv no...
