Why is Canada’s Price Level So Predictable?
Description: One of the pioneers of inflation targeting (IT), the Bank of Canada is now considering a possibility of switching to price-level-path targeting (PLPT), where past deviations of inflation from the target would have to be offset in the future, bringing the price level back to a predetermined path. This paper draws attention to the fact that the price level in Canada has strayed little from the path implied by the two percent inflation target since its introduction in December 1994, and has tended to revert to that path after temporary deviations. Econometric analysis using Bayesian estimation suggests that a low probability can be assigned to explaining this behavior by sheer luck manifesting itself in mutually offsetting shocks. Much more plausible is the assumption that inflation expectations and interest rates are determined in a way that is consistent with an element of PLPT. This suggests that the difference between IT as it is actually practiced (or perceived) and PLPT may be less stark than what pure theoretical constructs posit, and that the transition to a fullfledged PLPT regime will likely be considerably easier than what was previously thought. The paper also shows that inflation expectations are a major driver of actual inflation in Canada, which makes it easier to keep inflation close to the target without large output costs.

Microeconomic Implications of Remittances in an Overlapping Generations Model with Altruism and Self-Interest
Description: The paper explicitly models the dynamic strategic aspects of the interaction between the migrant and the remittance-receiving relative(s), with the migrant behaving as a Stackelberg leader. It is also different from other formalizations of remittance behavior in its treatment of the two parties' interaction to realize potential gains from exchange. We demonstrate that when the migrant and the relative(s) cooperate to maximize the joint utility of the household, this leads to higher level of remittances as well as investment and hours worked by the relative(s). We use data from Armenia to test our predictions regarding implications of remittances flows on behavior of receiving households. Consistent with our predictions, remittance-receiving households work fewer hours and spend less on the education of their children. While saving more, these households are not leveraging their savings to borrow from the banking system to expand their business activities. This evidence suggests that the benefits of remittances might be overstated and emphasizes the importance of measuring their impact in a general- rather than a partial-equilibrium context.

Taylor Rule Under Financial Instability
Description: This paper contributes to the analysis of monetary policy in the face of financial instability. In particular, we extend the standard new Keynesian dynamic stochastic general equilibrium (DSGE) model with sticky prices to include a financial system. Our simulations suggest that if financial instability affects output and inflation with a lag and if the central bank has privileged information about credit risk, monetary policy that responds instantly to increased credit risk can trade off more output and inflation instability today for a faster return to the trend than a policy that follows the simple Taylor rule with only the contemporaneous output gap and inflation.

Islamic Banks and Financial Stability: An Empirical Analysis
Description: The relative financial strength of Islamic banks is assessed empirically based on evidence covering individual Islamic and commercial banks in 18 banking systems with a substantial presence of Islamic banking. We find that (i) small Islamic banks tend to be financially stronger than small commercial banks; (ii) large commercial banks tend to be financially stronger than large Islamic banks; and (iii) small Islamic banks tend to be financially stronger than large Islamic banks, which may reflect challenges of credit risk management in large Islamic banks. We also find that the market share of Islamic banks does not have a significant impact on the financial strength of other banks.

Trade Restrictiveness in the CEMAC Region: The Case of Congo
Description: Congo's vital dependence on trade for development stands in contradiction with its trade policy. As a member of the CEMAC, Congo's tariff scheme at least formally is guided by CEMAC's 1994 trade regime agreement. This paper shows CEMAC's customs code is restrictive relative to that of comparable regional integration groups. The paper also discusses a number of quantitative and qualitative barriers to trade applied by Congo that render its current regime complex, nontransparent, and relatively unpredictable, compromising efforts to develop the non-oil sector and the country's export base. Moreover, Congo's high tariffs and other taxes have not led to higher fiscal revenues, as the number of exemptions granted in recent years has surged and customs administration remains weak.

Real Exchange Rates and Fundamentals: A Cross-Country Perspective
Description: This paper employs newly constructed measures for productivity differentials, external imbalances, and commodity terms of trade to estimate a panel cointegrating relationship between real exchange rates and a set of fundamentals for a sample of 48 industrial countries and emerging markets. It finds evidence of a strong positive relation between the CPI-based real exchange rate and commodity terms of trade. The estimated impact of productivity growth differentials between traded and nontraded goods, while statistically significant, is small. Increases in net foreign assets and in government consumption tend to be associated with appreciating real exchange rates.

Capital Flows and Economic Fluctuations: The Role of Commercial Banks in Transmitting Shocks
Description: This paper uses a general equilibrium model to examine the central role played by commercial banks in intermediating and amplifying the capital flow shocks to the local economy in the 1997 Asia financial crisis. It finds that a sudden stop of capital inflows affects the equilibrium credit supply through two channels: first, the plunge of foreign financing decreases the loanable funds directly; and second the sudden stop drives up the cost of providing banking services, thereby additionally reducing the available bank credit to firms through a "deposit run". Empirical results from a VAR model broadly support the theoretical implications.

International Reserves—Too Much of a Zipf’s Thing
Description: Concentrated distribution of international reserves is puzzling. I show that the growth rates of international reserves bear only a very weak relationship to their initial stocks (scaled by GDP or in absolute terms), and that, by implication, the cross-sectional distribution of reserves conforms to Zipf's law. The law states that the size of reserves is inversely related to their ranking. Evidence in favor of the law is strong and time robust. I compare the crosssection distribution of international reserves embedded in the WEO projections to that implied by Zipf's law and find that international reserves are much less concentrated in the WEO projections than implied by Zipf's law.

Evaluating Alternative Approaches to Poverty Alleviation: Rice Tariffs Versus Targeted Transfers in Madagascar
Description: This paper uses a partial equilibrium framework to evaluate the relative efficiency, distributional and revenue implications of rice tariffs and targeted transfers in Madagascar, especially in the context of identifying their respective roles for poverty alleviation. Although there are likely to be substantial efficiency gains from tariff reductions, these accrue mainly to higher income households. In addition, poor net rice sellers will lose from lower tariffs. Developing a system of well designed and implemented targeted direct transfers to poor households is thus likely to be a substantially more costeffective approach to poverty alleviation. Such an approach should be financed by switching revenue raising from rice tariffs to more efficient tax instruments. These policy conclusions are likely to be robust to the incorporation of general equilibrium considerations.

Spillovers Across NAFTA
Description: This paper examines linkages across North America by estimating the size of spillovers from the major regions of the world-the United States, euro area, Japan, and the rest of the world-to Canada and Mexico, and decomposing the impact of these spillovers into trade, commodity price, and financial market channels. For Canada, a one percent shock to U.S. real GDP shifts Canadian real GDP by some ¾ of a percentage point in the same direction- with financial spillovers more important than trade in recent decades. Thus, a large proportion of the reduction in Canadian output volatility since the 1980s can be accounted for by the "Great Moderation" in U.S. growth. Before 1996, domestic volatility in Mexico swamped the contribution of external factors to the business cycle. After 1996, the response of Mexican GDP is 1½ times the size of the U.S. shock-"when the U.S. sneezes, Mexico catches a cold". These spillovers are transmitted through both trade and financial channels.
