The international transactions accounts provide information on trade in goods and services (including the balance of payments and the balance of trade), investment income, and government and private financial flows. In addition, the accounts measure the value of U.S. international assets and...

Using structural VARs, I find that external shocks are an important source of macroeconomic fluctuations in emerging markets. Furthermore, U.S. monetary policy shocks affect quickly and strongly interest rates and the exchange rate in a typical emerging market. The price level and real output in...

While consumption habits have been utilised as a means of generating a hump shapedoutput response to monetary policy shocks in sticky-price New Keynesian economies,there is relatively little analysis of the impact of habits (particularly, external habits) onoptimal policy. In this paper we...

In practice, central banks have been confronted with a trade-off between stabilising inflation and output when dealing with rising oil prices. This contrasts with the result in the standard New Keynesian model that ensuring complete price stability is the optimal thing to do, even when an oil...

This paper seeks to disentangle the sources of correlations between high-, mid- and lowcap stock indexes from the German prime standard. In principle, such comovement can arise from direct spillover between the variables or due to common factors. By standard means, these different components are...

This paper is a progress report on understanding the relationship betweenprices and allocations of risks on financial markets versus macroeconomicchoices and allocations. In this paper, I investigate the scope of a modelwith exogenous habit formation – or “catching up with the Joneses”,...

Are ethnic specialization and thus a downward sloping labor demand curve fundamentalfeatures of labor market competition between ethnic groups? In a general equilibrium model,this paper argues that spillover effects in skill acquisition and social distances between ethnicgroups engender...

We decompose by origin the sources of the variation in real aggregate output and aggregate price level in the Czech Republic, Hungary and Poland. We find that a sizable fraction of the variation is attributable to external shocks, especially so for aggregate price level. We show that euroarea...

In the data, individual prices change frequently and by large amounts. In standardsticky price models, frequent and large price changes imply a fast response of the aggregate price level to nominal shocks. This paper presents a model in which price setting firms optimally decide what to observe,...
