Subject of the present study is the agent-based computer simulation of Agent Island. Agent Island is a macroeconomic model, which belongs to the field of monetary theory. Agent-based modeling is an innovative tool that made much progress in other scientific fields like medicine or logistics. In...

SINCE 1930, EXPECTATIONS HAVE PLAYED AN IMPORTANT ROLE IN ECONOMIC THEORY AND THIS IS BECAUSE ECONOMICS IS GENERALLY CONCERNED WITH THE IMPLICATIONS OF CURRENT ACTIONS FOR THE FUTURE. THIS PAPER THEREFORE ARGUES THAT THE DEVELOPMENT OF RATIONAL EXPECTATIONS THEORY WILL MAKE A MORE SIGNIFICANT...

While the IS/LM-AS/AD model is still the central tool of macroeconomic teaching it has been criticised by several economists. The model is unable to deal with a monetary policy that uses the interest rate as its operating target ( Romer [2000]). Walsh [2002] has criticised that it is not suited...

Emerging markets have experienced a sizeable decline in their neutral real interest rates until recently. In this paper we try to identify the main factors that contributed to it, with a focus on Brazil. We estimate an interval for Brazil's time-varying neutral rate based on a range of...

The theoretical foundation of inflation targeting was laid out by the Swedish economist Knut Wicksell (1851-1926) in his groundbreaking treatise, Interest and Prices, published originally in German in 1898. Here he proposed price stability as the rule for monetary policy. Today, inflation...

The sensitivity of U.S. aggregate investment to shocks is procyclical: the response upon impact increases by approximately 50% from the trough to the peak of the business cycle. This feature of the data follows naturally from a DSGE model with lumpy microeconomic capital adjustment. Beyond...

Microeconomic lumpiness matters for macroeconomics. According to our DSGE model, it explains roughly 60% of the smoothing in the investment response to aggregate shocks. The remaining 40% is explained by general equilibrium forces. The central role played by micro frictions for aggregate...

Much recent monetary policy analysis has featured stochastic simulations with small structural macroeconomic models that include: a spending vs. saving ( IS') sector; a price-adjustment sector; and an interest rate policy rule. The first two are frequently specified so as to reflect optimizing...

This work has objetive to discuss a new approach for the model IS-LM proposal by Romer (2000), which curved LM is substituted by a curved MP (monetary policy of the Central Bank). The work was motivated by the need of a more coherent model with the current economic reality for forecast and...

The paper presents an update of the structural macroeconometric model of the Polish economy NECMOD. The updated version of the model is, similarly as its predecessor, used at the National Bank of Poland for forecasting and policy simulation exercises. NECMOD is a hybrid, medium-scale and...
