In spite of elaborate descriptive and correlational studies, the most ubiquitous phenomenon in economics, namely inflation, has remained unexplained in terms of its mathematical origins. Keynes had attempted to relate inflation to a mechanism of "sticky wages and prices". Hitherto, such theories...

Deterministic simulations with the Reserve Bank of New Zealand’s core FPS model show how New Zealand’s broad macroeconomic environment might have evolved over the 1990s, if a US nominal yield curve and US TWI exchange rate movements under a common currency arrangement had been...

Most prices and interest rates display fluctuating levels that embody extractable energy and equivalent amounts of money. Such fluctuations are also associated with varying degrees of uncertainty. Shannon's derivations of spectral entropy and information content offer computational techniques...

This paper reviews the existing empirical evidence on the short-term impact on prices of fiscal variables and assesses it against new results from harmonised simulations, conducted with six well-established econometric models used by the ECB and five national central banks (NCBs) of the...

In this paper we assess the stability of open economy backward-looking Phillips curves estimated over two different exchange rate regimes. The pseudo-data employed in our econometric exercise come from the simulation of a New-Keynesian hybrid model suited for performing monetary policy analysis....

Using an optimisation-based model with endogenous labour supply and a proportional tax rate, we compare the stabilising properties of different fiscal policy rules. The economy is affected by shocks from both government spending and technology. The fiscal policy rule can be based on government...

Unanticipated inflation or deflation causes one party of a nominal contract to gain at the expense of the other party, an effect absent in macroeconomic models with one representative consumer or with consumers having identical consumption. In this paper's general dynamic and stochastic...

In this paper we introduce an application of the supply-side channel for fiscal policy to the basic New Keynesian model. We use a proportional tax rate instead of lump sum tax and introduce the distortions of a tax wedge. We derive a closed economy forward-looking model with government...

This paper shows the way how persistent world inflation shocks hitting a small open economy can re-weight the importance of domestic and foreign factors in the determination of prices. In this sense, we study why the recently observed global disinflation environment may imply a weakening of the...

The paper presents a structural model framework for a small open economy. The model, based on optimising households and firms, has been calibrated on Czech macroeconomic data in order to develop an analytic framework suitable for analysing key policy questions related to the Czech Republic’s...
