To what extent do national borders and national currencies impose costs that segment markets across countries? To answer this question we use a dataset with product level retail prices and wholesale costs for a large grocery chain with stores in the U.S. and Canada. We develop a model of pricing...

Relative cross-border retail prices, in a common currency, comove closely with the nominal exchange rate. Using product-level prices and wholesale costs from a grocery chain operating in the United States and Canada, we decompose this variation into relative costs and markup components. The high...

The paper proposes a unified framework to study the dynamics of net foreign assets and exchange rate movements. We show that deteriorations in a country's net exports or net foreign asset position have to be matched either by future net export growth (trade adjustment channel) or by future...

Three of the most important recent facts in global macroeconomics - the sustained rise in the US current account deficit, the stubborn decline in long run real rates, and the rise in the share of US assets in global portfolio - appear as anomalies from the perspective of conventional wisdom and...

We explore the implications of a country's external constraint for the dynamics of net foreign assets, returns, and exchange rates. Deteriorations in external accounts imply future trade surpluses (trade channel) or excess returns on the net foreign portfolio (valuation channel). Using a new...

We examine the extent to which vertical and horizontal market structure can together explain incomplete pass-through. We develop a model that highlights the interactions between horizontal and vertical structure and their effects on pass-through from commodity to wholesale prices and wholesale...
