The Impact of a Disorderly Resolution of Global Imbalances on Global Wealth

Partly reflecting structural advantages such as liquidity and strong investor protection, foreigners have built up extremely large positions in US (as well as other dollar‐denominated) financial assets. This paper describes the impact on global wealth of an unanticipated shock to US financial markets. For every 10 per cent decline in the dollar, US equity markets, and US bond markets, total wealth losses to foreigners could amount to about 5 percentage points of foreign GDP. Four stylized facts emerge: (i) foreign countries, particularly emerging markets, are more exposed to US bonds than to US equities; (ii) over time US exposure has increased for most countries; (iii) on average, US asset holdings of developed countries and emerging markets (scaled by GDP) are very similar; and (iv) based on their reserves position alone, wealth losses of emerging market governments could on average amount to about 2¾ percentage points of their GDP.     

The turning black tide: energy prices and the Canadian dollar

Abstract.  This paper revisits the relationship between energy prices and the Canadian dollar, using an equation first developed by Amano and van Norden (1995) . They found evidence of a negative relationship between these two variables, such that higher real energy prices led to a depreciation of the Canadian dollar. Based on structural break tests, we find a break point in the sign of this relationship, which changes from negative to positive in the early 1990s. The timing of the break is consistent with major changes in Canada's energy policies and in energy-related cross-border trade and investment.     

Changing International Financial Architecture: Growing Chinese Influence?

It is often said that the 21st century will be the Asian century. Based on population and gross domestic product projections, it certainly looks as if this will be so. Will the existing international financial institutions give more voices, votes, and top positions to Asia? Or will Asia create its own institutions that would rival the old architecture? This present paper argues, first, that China, and possibly India, will be in a position to be so influential that the international financial architecture may have to go through significant changes. Second, the three large crises in the last 20 years have made Asian countries more confident that they can manage capital flows by accumulating large foreign reserves and by adopting sound macrofinancial policies. After 2009, China started to push various initiatives that will amount to creating its own sphere of influence with new regional institutions in the future.     

Exchange rate puzzles: A tale of switching attractors

The rational expectations efficient market model of the exchange rate has failed empirically. In this paper, we develop a model of the exchange rate in which agents use simple forecasting rules. Based on an ex post evaluation of the relative profitability of these rules they decide whether to switch or not. In addition, transactions costs in the goods market are introduced. We show that this simple model creates great complexity in the market which is characterised by the fact that the exchange rate is disconnected from its fundamental most of the time. Finally we show that this model mimicks most of the empirical puzzles uncovered in the literature.     

Risk aversion,exchange‐rate uncertainty,and the law of one price: insights from the market for online air‐travel tickets

Abstract We argue that risk aversion driven by exchange‐rate uncertainty causes a wedge between the domestic and foreign prices of a homogeneous good. We test our hypothesis using a unique micro‐data set from a market with minimum imperfections. The empirical findings validate our hypothesis, as accounting for exchange‐rate uncertainty we are able to explain a significant proportion of deviations from the law of one price. Overall, our analysis suggests the possibility of a new solution to the purchasing power parity puzzles.     

Exchange-rate pass-through at the product level

Abstract.  We use a detailed database to investigate exchange-rate pass-through at the product level for a large number of countries. The empirical analysis suggests that pricing behaviours are dichotomous, with complete pass-through in around 25% of sectors and significant pricing-to-market in the remaining ones. Average long-run pass-through coefficient is close to 80%; this result hides a strong heterogeneity of pass-through behaviours across sectors. Even when composition effects are controlled for, average pass-through varies across importing countries. The econometric analysis shows that pass-through tends to be higher in volatile environments; in less developed countries; in weakly integrated markets.     

The effect of firm-level productivity on exchange rate pass-through

A heterogeneous-firm trade model can explain the recent decrease in exchange rate pass-through to aggregate US import prices as a result of decreased trade costs. This paper finds support for this explanation by testing another implication of this type of heterogeneous firm model: lower exchange rate pass-through for goods that are traded for short periods of time.     

External wealth, the trade balance, and the real exchange rate

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.     

Has Australia's floating exchange rate regime been optimal?

This paper develops a straightforward theoretical framework for evaluating exchange rate regime choice for small economies. It proposes that a floating exchange rate minimises national income and employment variation when real macroeconomic shocks predominate, whereas a pegged exchange rate achieves this goal should monetary shocks predominate. It then shows econometrically that, in the case of Australia, a floating exchange rate best suited the economy for the period 1985 to 2010, because real shocks were more significant than monetary shocks. Moreover, consistent with the theory, further results showing that a stronger (weaker) exchange rate correlated with positive (negative) deviations from trend GDP affirm that a floating exchange rate regime was optimal for Australia over this time.

Currency substitution,inflation, and welfare

Currency substitution affects the mapping between social welfare and inflation by altering the underlying money demand function and influencing interest rates. In order to explore the essence of this effect, I build a model with working capital under which foreign currency is substituted with the less liquid components of domestic money. The framework closely mimics the actual pattern of currency substitution across varying rates of inflation and enables the study of an additional channel that works through the impact of currency substitution on interest rates. It is found that there is a threshold inflation rate, which turns out to be 44% under baseline calibration, below which currency substitution decreases welfare and vice versa. A practical implication is that, at inflation rates lower (greater) than the threshold, the potential welfare gains from disinflation to a near-zero inflation rate are higher (lower) if there is currency substitution than otherwise.     

Financial constraints,firm entry,and exchange rate pass-through

Using a heterogeneous firm model with firm entry and endogenous markups, I study how the financial constraints of exporting firms affect exchange rate pass-through behaviors. I find that the financial constraints increase the degree of exchange rate pass-through.     

The coordination channel of foreign exchange intervention: A nonlinear microstructural analysis

Taylor (1994, 1995) [Taylor, M.P., 1994. Exchange rate behaviour under alternative exchange rate regimes. In: Kenen, P. (Ed.), Understanding Interdependence: The Macroeconomics of the Open Economy. Princeton University Press, Princeton; Taylor, M.P., 1995. The economics of exchange rates. Journal of Economic Literature 33, 13-47] has proposed the coordination channel as a means by which foreign exchange market intervention may be effective, in addition to the traditional portfolio balance and signalling channels. If strong and persistent misalignments of the exchange rate are caused by nonfundamental influences, such that a return to equilibrium is hampered by a coordination failure among fundamentals-based traders, then official intervention may act as a coordinating signal, encouraging stabilising speculators to re-enter the market at the same time. We develop this idea in the framework of a simple microstructural model of exchange rate movements, which we then estimate using daily data on the dollar-mark exchange rate and on Federal Reserve and Bundesbank intervention operations. The results are supportive of the existence of a coordination channel of intervention effectiveness.     

The behaviour of relative prices in the European Union: A sectoral analysis

Using multivariate unit root test methods, this paper investigates the Purchasing Power Parity (PPP) hypothesis at the sectoral level across six European countries over the last 17 years. Evidence of mean reversion towards PPP is found for the relative prices of some sectors and countries. Mean reversion in relative prices is explained by cross-country and cross-sectoral characteristics such as the distance between countries, nominal exchange rate volatility, differences in GDP per capita, non-tariff barriers, research and development, advertising, industrial concentration and tradeability of the products.     

Monetary and Fiscal Policy Rules in the EMU

Abstract. This paper studies the design and effects of monetary and fiscal policy in the euro area. To do so, a stylized two‐region model of monetary and fiscal policy rules in the EMU is built. We analyse how monetary and fiscal rules affect the adjustment dynamics in the model. Both the effects on the individual countries and on the EMU aggregate economy are studied. Three aspects play an important role in the analysis: (i) the consequences of alternative monetary and fiscal policy rules, (ii) the consequences of asymmetries between EMU countries (asymmetries in macroeconomic shocks and macroeconomic structures), and (iii) the role of alternative degrees of backward‐ and forward‐looking behaviour in consumer decisions and inflation expectations.
