We develop a theory of money and credit as competing payment instruments, then put it to work in applications. Buyers can use cash or credit, with the former (latter) subject to the inflation tax (transaction costs). Frictions making the choice of payment method interesting also imply equilibrium price dispersion, and together these deliver closed-form solutions for money demand. The model can ...

Waves of globalization reflect the historical technical progress and modern economic growth. The dynamics of this process are here approached using the multidimensional scaling (MDS) methodology to analyze the evolution of GDP per capita, international trade openness, life expectancy, and education tertiary enrollment in 14 countries. MDS provides the appropriate theoretical concepts and the ex...

Using a New-Keynesian framework, we investigate how far the inflationary processes in member states of EMU cause regional price levels to converge. We fail to produce hard evidence of the present existence of such an adjustment mechanism, notwithstanding that inflation in some countries tends to converge towards the euro area level. Overall, inflation persistence has declined significantly over...

This paper presents a theory of inflation in an economy with commodity money and supports it by evidence from the inflationary episodes in France during the fourteenth and fifteenth centuries. The paper shows that commodity money can be inflated similarly to fiat money through repeated debasements, which act like devaluation. Furthermore, as with fiat money, demand for commodity money falls wit...

Phillips curves are central to discussions of inflation dynamics and monetary policy. New Keynesian Phillips curves describe how past inflation, expected future inflation, and a measure of real marginal cost or an output gap drive the current inflation rate. This paper studies the (potential) weak identification of these curves under generalized methods of moments (GMM) and traces this syndrome...

This paper reviews analytical work carried out by central banks that participated in the Autumn Meeting of Central Bank Economists on “The evolving inflation process” which the BIS hosted on 28-29 October 2005. The paper first discusses efforts to document the univariate statistical properties of inflation and how they have changed over the last decades. It then reviews studies of disaggregated...

In brane inflationary scenarios, the cosmological perturbations are supposed to originate from the vacuum fluctuations of the inflaton field corresponding to the position of the brane. We show that a significant, and possibly dominant, contribution to the curvature perturbation is generated at the end of inflation through the vacuum fluctuations of fields, other than the inflaton, which are lig...

abstract in this paper, the effect of foreign sector macro-variable on inflation dynamics and firms’ pricing behavior has been investigated in the context of a small open economy new keynesian phillips curve. this curve is derived and estimated for a developing oil-exporting economy suffering from dutch disease. this version of nkpc is an extension of leith and malley’s (2007) small open econom...

In this paper we identify the main determinants of the exchange rate regimes in Central and Eastern European Countries (CEECs). For this purpose, we use an ordered logit model for the official (de jure) and the actual (de facto) exchange rate classifications. We find that trade openness and concentration, inflation differentials, international reserves stocks, and financial conditions are the m...
