Do global current account imbalances still matter in a world of deep international financial markets where gross two-way financial flows often dwarf the net flows measured in the current account? Contrary to a complete markets or 'consenting adults' view of the world, large current account...

The elasticity of substitution between goods from different countries—the Armington elasticity—is important for many questions in international economics, but its magnitude is subject to debate: the "macro" elasticity between home and import goods is often found to be smaller than the...

Greater financial integration between core and peripheral EMU members had an effect on both sets of countries. Lower interest rates allowed peripheral countries to run bigger deficits, which inflated their economies by allowing credit booms. Core EMU countries took on extra foreign leverage to...

Banking systems have rapidly grown to a point where for many countries bank assets amount to multiples of GDP. As a consequence, government’s capacity to provide stability-enhancing fiscal guarantees against systemic crises can no longer be taken for granted. As regulation of dynamic financial...

This paper makes a case that the global imbalances of the 2000s and the recent global financial crisis are intimately connected. Both have their origins in economic policies followed in a number of countries in the 2000s and in distortions that influenced the transmission of these policies...

The interwar period was marked by the end of the classical gold standard regime and new levels of macroeconomic disorder in the world economy. The interwar disorder is often linked to policies inconsistent with the constraint of the open-economy trilemma - the inability of policy-makers...

The New Open Economy Macroeconomics has allowed economists to tackle classical problems with new tools, while also generating new ideas and questions. In their attempts to make the new models capture empirical regularities, researchers have entertained a variety of assumptions about the...

This paper studies the mechanisms of international payments adjustment at work under the Bretton Woods system of fixed exchange rates between 1945 and 1971. I argue that two market failures - imperfect international capital mobility and imperfect wage-price flexibility - are central to...

Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. We show that even were this the case, there remains a...

This paper studies the merits of policy rules with escape clauses, analysing as an example fixed exchange rate systems that allow member countries the freedom to realign in periods of stress. Motivating this example is the debate within the European Monetary System over how quickly to move from...
