The data mining technique of time series clustering is well established in many fields. However, as an unsupervised learning method, it requires making choices that are nontrivially influenced by the nature of the data involved. The aim of this paper is to verify usefulness of the time series...

Economic theory is prone to hysteresis. Once an idea is adopted, it is difficult to change. In the 1970s, the economics profession abandoned the Keynesian Phillips curve and adopted Milton Friedman's natural rate of unemployment (NRU) hypothesis. The shift was facilitated by a series of lucky...

We study the revision of survey expectations in response to macroeconomic shocks, which we identify in vector autoregressive models with sign restrictions. We find that survey respondents distinguish between movements along the Phillips curve and shifts of the Phillips curve, depending on the...

We use survey data to study how consumers assess the macroeconomic effects of structural oil market shocks on the U.S. economy using vector autoregressive models. To structurally decompose oil price changes, we impose sign restrictions on impulse responses. We find that the survey respondents'...

Serial correlation in macroeconomics is pervasive. Macroeconomic modellers find it impossible to model this feature without relying on serially correlated shocks. Using a behavioral macroeconomic model, I show that serial correlation in inflation and output can easily be explained in the context...

This study seeks to examine the effects of trade diversification on macroeconomic performance in Nigeria. To achieve this, the study employs bound test of ARDL to determine the existence of cointegration between trade diversification and key macroeconomic variables. We further estimate the...

This paper focuses on macroeconomic interdependencies between the Euro area and three transition economies (Estonia, Lithuania and Latvia), with the aim of establishing whether the latter are ready to adopt the Euro. The theoretical framework is based on the Generalised Purchasing Power Parity...

Die Schaffung eines einheitlichen Geldes in Europa und die Vergemeinschaftung der Geldpolitik bedeuten eine einschneidende institutionelle Änderung. In diesem Beitrag wird analysiert, was zu tun und was zu lassen ist, damit das historisch bedeutsame Vorhaben ein Erfolg wird. Zwölf...

In an evolutionary approach to macroeconomics, the market disequilibrium dynamics resulting from structural change need to be properly represented at the aggregate level. As suggested by the late F.A.Hayek, a suitable equilibrium concept required to this end as a frame of reference, is that of a...

This paper examines the effects of fiscal policy measures on GDP and the government budget balance in a structural VAR model. In order to identify expenditure shocks we follow Blachard/Perotti (2002) and assume that government expenditure is partly predetermined in the budget. For the...
