We construct a simple firm-based model of global interdependence. We show how extremely strong statistical correlations can naturally develop between countries even if the interconnections between those countries remain very weak. Potential policy implications of this result are also discussed.

The growth of East Asia's intra-regional trade is driven largely by increased component trade within global electronics production networks. Data on both electronics trade and production elucidate a pattern of specialization in which upper- and middle-income countries produce sophisticated...

This paper develops a two-country macro model with endogenous tradability to study features of international economic integration. Recent episodes of integration in Europe and North America suggest some surprising observations: while quantities of trade have increased significantly, especially...

We use consumer price data for 205 cities/regions in 21 countries to study PPP deviations before, during and after the major currency crises of the 1990s. We combine data from industrialized nations in North America (Unites States, Canada and Mexico), Europe (Germany, Italy, Spain and Portugal),...

This study proposes a new measure of the tradability of 120+ commodities based on price dispersion. This approach is used to construct price indices of tradables and non-tradables for 150+ countries. The expenditure share of tradables is lower for richer countries, while the relative price of...

We use CPI data for U.S. and Canadian cities for 14 categories of consumer prices to examine the nature of the deviations from the law of one price. The distance between cities explains a significant amount of the variation in the prices of similar goods in different cities. But the variation of...

The empirical literature on contagion has mainly measured the propagation of shocks across countries using daily stock markets, interest rates, and exchange rates. Several methodologies have been used for this purpose, however, the properties of the data introduces important limitations on the...

I identify new patterns in countries' economic performance over the 2007-2014 period based on proximity through distance, trade, and finance to the US subprime mortgage and Eurozone debt crisis areas. To understand the causes of the cross-country variation, I develop an open economy model with...

This paper studies the role of cross-border supply-chains for international financial contagion. Following large country-level shocks abroad, such as country-index return jumps and natural disasters, the dynamic conditional correlation (DCC) of stock returns between U.S. suppliers and their...

The accumulation of large amount of sovereign reserves has fuelled an intense debate on the associated costs. In a world with liquidity crises and strategic default, we model a contracting game between international lenders and a country, which delivers the country's optimal portfolio choice and...
