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...

This paper points out an empirical failing of real business cycle models in which unemployment is endogenized through a matching function. One can easily choose a calibration to make the cyclical fluctuation in unemployment as large in the model as it is in the data, or to make the response of...

This paper develops a method that uses a likelihood approach to directly compare two or more non-nested dynamic, stochastic general equilibrium (DSGE) models. It is shown how DSGE models can be compared across the whole sample and how this measure can be decomposed across individual observations...

A key parameter in real business cycle models is the weight on the utility of leisure. Typically this parameter is chosen so that the steady-state level of work activity matches the corresponding measure in the data, i.e. the amount of time workers spend in market activity. While the calibration...

This paper elaborates on the relative importance of sectoral shocks for real economic activity in Germany. Implications of multisectoral real business cycle models are examined by resorting to testing techniques based on stock market returns. The empirical evidence is obtained by calculating...

This paper incorporates an uncoordinated struggle for extra fiscal favors into an otherwise standard Dynamic Stochastic General Equilibrium model. This reflects the popular belief that interest groups compete for privileged transfers and tax treatment at the expense of the general public...

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...
