This paper introduces a new trade model type. It combines the gravity model, well-known in international economics, with network theory. With this approach, complicated trade networks can be algebraically solved in form of systems of linear (differential) equations. Business cycles and productivity shocks can be represented via complex numbers or the Laplace transformation. With the help of thi...

The economic performances of the Eurozone look weaker than those of the United States over the period 1999-2006, in spite of the fact that the former applies more thoroughly the 'new macroeconomics' governance rules concerning public deficits and inflation control. The literature emphasizes Alan Greenspan's pragmatism when discussing the relative success of the Fed, but the reasons why pragmati...

In this paper we investigate the empirical pass-through of the nominal exchange rates to the consumer price indexes (CPIs) for five Eurozone countries vis-à-vis the United States. There are significant structure changes in these countries during the European integration. The Eurozone CPIs have been insulated from the exchange rate shocks since that integration; on the other hand, we find that t...

This paper is an extension of the debate on the nexus between the strength of IPRs and prospects for knowledge economy. It assesses the relationships between software piracy and scientific publications in African countries for which data is available. The findings which reveal a positive nexus are broadly consistent with the school of thought postulating that, the East Asian miracle has been la...

Objective – The circular economy aims to preserve the value of products and materials within a closed supply chain. existing models decision-making methods for managing end product life cycle are mostly focused on economic aspects. While is aimed at combining environmental, social goals. This article develop model enterprise disposal used products, taking into account socio-environmental factor...

In Kohler (2002) we analyse coalition formation in monetary policy coordination games between n countries. We find that positive spillovers of the coalition formation process and the resulting free-rider problem limit the stable coalition size: since the coalition members are bound by the union’s discipline, an outsider can successfully export inflation without fearing that the insiders will tr...

Building on previous literature, we assess when foreign aid is effective in fighting terrorism using quantile regressions on a panel of 78 developing countries for the period 1984-2008. Bilteral, multilateral and total aid indicators are used whereas terrorism includes: domestic, transnational, unclear and total terrorism dynamics. We consistently establish that foreign aid (bilateral, multilat...

In this paper, we look at the role of export composition in the growth process, considering how increased similarity in trade structure among countries can induce catching-up in income levels in a group of countries in transition. We analyze the sectoral export patterns of the Central and Eastern European countries (CEECs) by comparing them to those of the current members of the European Union ...
