Why is GDP so much more volatile in poor countries than in rich ones? To answer this question, we propose a theory of technological diversification. Production makes use of different input varieties, which are subject to imperfectly correlated shocks. As in endogenous growth models,...

This paper endeavours to provide a comprehensive analysis of the nature and the possible importance of “global excess liquidity”, a concept which has attracted considerable attention in recent years. The contribution of this paper is threefold. First, we present some conceptual discussion on...

In this paper we present a two-country dynamic general equilibrium model of ex ante unequally developed countries. The model explains a key feature recently observed in transition economies – the long-run trend real exchange rate appreciation – through investments into quality. Our...

The reaction of exports to real exchange rate movements can differ according to the nature of the destination country. We derive and estimate a gravity equation for 20 OECD exporting countries and 52 developed and developing importing countries. We test how trade costs dampen the effect of real...

This paper aims at showing heterogeneity in the degree of exchange rate pass-through to import prices in major advanced economies at three different levels: 1) across destination markets; 2) across types of exporters (distinguishing developed economy from emerging economy exporters); and 3) over...

This paper explores implications of climate change for fiscal policy by assessing the impact of large scale extreme weather events on changes in public budgets. We apply alternative measures for large scale extreme weather events and conclude that the budgetary impact of such events ranges...

The impact of currency collapses (i.e. large nominal depreciations or devaluations) on real output remains unsettled in the empirical macroeconomic literature. This paper provides new empirical evidence on this relationship using a dataset for 108 emerging and developing economies for the period...

We search for early warning indicators that could indicate important risks in developed economies. We therefore examine which indicators are most useful in explaining costly macroeconomic developments following the occurrence of economic crises in EU and OECD countries between 1970 and 2010. To...

We construct and explore a new quarterly dataset covering crisis episodes in 40 developed countries over 1970–2010. First, we examine stylized facts of banking, debt, and currency crises. Banking turmoil was most frequent in developed economies. Using panel vector autoregression, we confirm...

We show that traditional gravity variables play a significant role in explaining trade flows related to global value chain participation. We find evidence that cooperation costs – measured by linguistic and geographical proximity – are more relevant for trade that reflects cross-border...
