This paper develops a New-Keynesian Dynamic Stochastic General Equilibrium (NKDSGE) model for forecasting the growth rate of output, inflation, and the nominal short-term interest rate (91 days Treasury Bill rate) for the South African economy. The model is estimated via maximum likelihood...

Both from theoretical and practical viewpoints, I argue that the New Keynesian model's forward-looking IS curve should be derived by quadratic approximation. This leaves uncertainty in the basic three-equation model. After adding exogenous AR(1) processes, I examine the results by numerical...

We construct a new-Keynesian DSGE model tailored to the Netherlands and interpret it as a multivariate unobserved components model. We identify three major stochastic trends in the data — trends in general - purpose technology, investment-specific technology, and labor supply — and model...

Dynamic stochastic general equilibrium models have recently become standard tools for policy-oriented analyses. Nevertheless, their forecasting properties are still barely explored. We fill this gap by comparing the quality of real-time forecasts from a richly-specified DSGE model to those from...

This paper describes the Macedonian Policy Analysis Model (MAKPAM), which is used at the National Bank of the Republic of Macedonia (NBRM) for medium term macroeconomic forecasting and policy analysis. The MAKPAM is a medium scale, New Keynesian gap model that incorporates the key...

This chapter aims to provide a hands-on approach to New Keynesian models and their uses for macroeconomic policy analysis. It starts by reviewing the origins of the New Keynesian approach, the key model ingredients and representative models. Building blocks of current-generation dynamic...

Bruun and Heyn-Johnsen (2009) state the paradox that economics has failed to provide a satisfactory explanation of how monetary profits are generated, even though the generation of a physical surplus is an established aspect of non-neoclassical economics. They emphasise that our ability to...

This paper analyses the theoretical and policy implications of assuming firm-specific lumpy investment behaviour by firms and compares such implications to those occurring when adopting different investment specifications in a new-Keynesian framework. We develop numerical simulations of the...
