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...

We propose that analysis of purchasing power parity (PPP) and the law of one price (LOOP) should explicitly take into account the possibility of ‘commodity points’ – thresholds delineating a region of no central tendency among relative prices, possibly due to lack of perfect arbitrage in...

This paper surveys the performance of international capital markets and the literature on measuring international capital mobility. Three main functions of a globally integrated and efficient world capital market provide focal points for the analysis. First, asset-price arbitrage ensures that...

Simple techniques of regulated Brownian motion are used to analyse the behaviour of the exchange rate when official policy reaction functions are subject to future stochastic changes. We examine exchange rate dynamics in cases where the authorities promise (i) to confine a floating rate within a...

This paper develops a dynamic model of seigniorage in which economies' equilibrium paths reflect the ongoing strategic interaction between an optimizing government and a rational public. The model extends existing positive models of monetary policy and inflation by explicitly incorporating the...

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...

The rapid growth of international reserves|a development concentrated in the emerging markets|remains a puzzle. In this paper we suggest that a model based on financial stability and financial openness goes far toward explaining reserve holdings in the modern era of globalized capital markets....
