Tiny changes in the American monetary policy can have dramatic effects on the rest of the world because of dollar's double role of national and international currency. This is the Triffin dilemma. The paper shows how it works through three examples: price of commodities, dollarization, and the...

Business cycle correlations are state-dependent and higher in recessions than in expansions. In this paper, I suggest a mechanism to explain why this is the case. For this purpose, I build an international real business cycle model with occasionally binding constraints on capacity utilization...

This paper studies the impact of the state-dependent risk of a government default on the correlation of the scal balance and current account. We use a small open economy model where nonlinear risk premia arise endogenously when the government operates close to its scal limit, i.e. the maximum...

This paper relates the inflationary impact of commodity price shocks across countries to a broad range of structural characteristics and policy frameworks over the period 2001-2010, using several approaches. The analysis suggests that economies with higher food shares in CPI baskets, fuel...

This paper provides a broad brush look at the impact of fluctuations in global food prices on domestic inflation in a large group of countries. For advanced economies, we find that these fluctuations have played a significant role over the period from 1960 to the present, but the impact has...

The weak global GDP growth since the financial crisis in 2007-2009 has coincided with unusually weak growth in global trade. Organisations that monitor international macro-economic development have identified growing protectionism – not least the increase in non-tariff barriers to trade, such...

How should monetary policy respond to large fluctuations in world food prices? We study this question in an open economy model in which imported food has a larger weight in domestic consumption than abroad and international risk sharing can be imperfect. A key novelty is that the real exchange...

Population aging challenges the financing of social security systems in developed economies, as the fraction of the population in working age declines. The resulting pressure on capital-labor ratios translates into a pressure on factor prices and production. While European countries all face...

Some of the topical problems of the harmonization of the global economy are outlined.Harmony is treated in Physical Macroeconomics as a dynamic balance of all energy and informational factors. Harmony is an objective property of the sustainable development of all living systems.Primarily,...

The paper continues a series of publications on the natural science foundations of the global economy. Physical macroeconomics treats the global economy as a living system, formed during biological and socio-economic evolution.In this Part VI of physical macroeconomics, qualitatively...
