The sharp depreciation of the Canadian dollar and the successful launch of the euro have sparked a lively debate in Canada about the possible benefits of formally adopting the U.S. dollar as our national currency. Some observers have suggested that this debate is largely irrelevant, since Canada is already highly "dollarized." Canadian businesses and households, they assert, often use the U.S. dollar to perform standard money functions in preference to their own currency. Very little evidence has been provided, however, to support these claims. The authors review the available data with a view to drawing some tentative conclusions about the extent to which Canada has already been informally dollarized. The evidence suggests that many of the concerns that have been expressed about the imminent demise of the Canadian dollar have been misplaced. The Canadian dollar continues to be used as the principal unit of account, medium of exchange, and store of value within our borders. Moreover, there is no indication that dollarization is likely to take hold in the foreseeable future. Indeed, in many respects, the Canadian economy is less dollarized now than it was 20 years ago.

This article examines the concept of purchasing-power parity (PPP) and its implications for the equilibrium value of the Canadian exchange rate. PPP has two main applications, as a theory of exchange rate determination and as a means to compare living standards across countries. Concerning exchange rate determination, PPP is mainly useful as a reminder that monetary policy has no long-run impact on the real exchange rate, since the exchange rate can deviate persistently from its PPP value in response to real shocks. To compare living standards across countries, PPP exchange rates constructed by comparing the prices of national consumption baskets are used to translate per capita national incomes into a common currency. These rates are useful because they offset differences in national price levels to obtain comparable measures of purchasing power, but they are not an accurate measure of the equilibrium value of the exchange rate. The authors conclude that the current deviation of the Canadian exchange rate from the PPP rate does not imply that the exchange rate is undervalued, but that this deviation reflects the impact of persistent real factors, in particular, lower commodity prices.

This paper reviews both the theoretical and empirical literature on the impact of common currencies on financial markets and evaluates the first three years of experience with Economic and Monetary Union (EMU).

In this paper, we study the impact of supply shocks on the Canadian real exchange rate. We specify a structural vector-error-correction model that links the real exchange rate to different fundamentals.

This paper develops and estimates a dynamic general-equilibrium sticky-price model that accounts for real exchange rate persistence.

The sharp depreciation of the Canadian dollar and the successful launch of the euro have spawned an animated debate in Canada concerning the potential benefits of formally adopting the U.S. dollar as our national currency.

Previous studies on whether the nature of the exchange rate regime influences a country's medium-term growth performance have been based on a tripartite classification scheme that distinguishes between pegged, intermediate, and flexible exchange rate regimes.

This paper clarifies the role and the impact of foreign exchange dealers in the relationship between foreign exchange intervention and nominal exchange rates using a unique dataset that disaggregates trades by dealer and by type of trade.

Since 1995, acquisitions of foreign firms by Canadian residents and acquisitions of Canadian firms by foreign residents have increased. Through most of this period, the dollar has depreciated, but the cumulative net balance of foreign direct investment acquisition flows has remained close to zero. The recent upward trend in bilateral acquisition flows is part of the globalization process as firms consolidate and rationalize their operations, and is not related to the value of the Canadian dollar. Standard models of international asset pricing imply that there should not be a relationship between the Canadian exchange rate and foreign takeovers of Canadian firms because an exchange rate movement does not give foreign buyers a systematic advantage over domestic buyers. Purchases of domestic firms by foreign residents are likely to be welfare-improving. Transactions between foreign and domestic residents are voluntary, and they imply that the foreign buyers expect to obtain higher profits from the firms' assets.

Traditional models of exchange rate regimes ignore the destabilizing effects of sharp and unanticipated exchange rate movements.
