- Abstract:
- Recent studies that have emphasized the costs of accumulating reserves for self-insurance purposes have overlooked two potentially important side-effects. First, the impact of the resulting lower spreads on the service costs of the stock of sovereign debt, which could substantially reduce the marginal cost of holding reserves. Second, when reserve accumulation reflects countercyclical LAW central bank interventions, the actual cost of reserves should be measured as the sum of valuation effects due to exchange rate changes and the local-to-foreign currency exchange rate differential (the inverse of a carry trade profit and loss total return flow), which yields a cost that is typically smaller than the one arising from traditional estimates based on the sovereign credit risk spreads. We document those effects empirically to illustrate that the cost of holding reserves may have been considerably smaller than usually assumed in both the academic literature and the policy debate.

- Abstract:
- Exchange rates have been changed unusually large these days. From 2011 to 2016, the Euro and the Japanese Yen have depreciated against the US Dollar by more than 25 percent. According to a theory, since competitively valued exchange rate helps to boost export growth, we should have observed a sub-stantial increase in export in the EU and Japan. However, the effectiveness of the exchange rates on exports appears to be weak across countries. This anomaly is one of the central puzzles in international macroeconomics: why large movements in the exchange rate have modest effects on the aggregate variables such as import prices, consumer prices, and quantity of exports. In this paper, we examines the role of global production linkages on ex-change rate elasticities by using Korean firm-level data. At firm-level, foreign-owned firms or firms with foreign subsidiaries participated in the Global Value Chains (GVC) play an important role in weakening the effect of ex-change rate movements on firm exports. The empirical results show that the exchange rate elasticity of total export is about -0.64, which implies that 10% appreciation of Korean Won would make a drop in total export by 6.4%. However, the exchange rate elasticities of firms are not the homogeneous across firms. We find that the exchange rate elasticities of firm exports are significant and negative for domestic-owned firms and firms without foreign subsidiary whereas those are insignificant for foreign-owned firms and firms with foreign subsidiaries. After controlling exports to foreign affiliates, we still find that the estimated exchange rate elasticities of exports are statistically insignificant, but become negative and relatively larger for firms with global production linkages. More-over, firms with higher GVC integration measure or more imported inter-mediate inputs have the significantly lower exchange rate elasticities of firm exports. It suggests that developments of global production linkages via firm ownership, within-industry or within-firm in the last decade play an essential role in alleviating the effect of exchange rate movements on the firm exports.

4. Global Monetary Policy Divergence and the Reemergence of Global Imbalances

- Abstract:
- Developed economies are paying remarkably little attention to coordinating their monetary policies. This is an unavoidable consequence of the independence of central banks, which faithfully follow their purely domestic mandates except in times of crisis. As a result, global monetary policies have reached unprecedented levels of divergence. This divergence is set to widen—primarily due to differences in the relative strength of labor markets—while global current account imbalances return. Meanwhile, exchange rates have not reacted as economists expected; the dollar has weakened even as policy rates have increased. Economic tensions will likely become more disruptive the longer global imbalances go uncorrected. Likewise, the global economy will become more vulnerable to shocks. Yet by focusing on bilateral trade imbalances, the United States has mistakenly singled out China when the global imbalances between the United States and the eurozone is the more critical issue. The growing global imbalances are reflected more in the eurozone current account surplus and U.S. fiscal policy than in China’s shrinking surplus.

5. Classifying Exchange Rate Regimes: 15 Years Later
- Author:

- Abstract:
- Levy Yeyati and Sturzenegger (2001, 2003, 2005) proposed an exchange rate regime classification based on cluster analysis to group countries according to the relative volatility of exchange rates and reserves, thereby shifting the focus from a de jure to de facto approach in the empirical analysis of exchange rate policy. This note extends the classification through 2014 and broadens the country sample, increasing the number of classified country-year observations from 3335 to 5616. Based on this extension, the note documents the main stylized facts in the 2000s, including the behavior of exchange rate policy around the global financial crisis, and the prevalence of floating regimes.

6. The Taylor Rule and Interval Forecast For Exchange Rates

- Abstract:
- This paper attacks the Meese-Rogoff (exchange rate disconnect) puzzle from a different perspective: out-of-sample interval forecasting. Most studies in the literature focus on point forecasts. In this paper, we apply Robust Semi-parametric (RS) interval forecasting to a group of Taylor rule models. Forecast intervals for twelve OECD exchange rates are generated and modified tests of Giacomini and White (2006) are conducted to compare the performance of Taylor rule models and the random walk. Our contribution is twofold. First, we find that in general, Taylor rule models generate tighter forecast intervals than the random walk, given that their intervals cover out-of-sample exchange rate realizations equally well. This result is more pronounced at longer horizons. Our results suggest a connection between exchange rates and economic fundamentals: economic variables contain information useful in forecasting the distributions of exchange rates. The benchmark Taylor rule model is also found to perform better than the monetary and PPP models. Second, the inference framework proposed in this paper for forecast-interval evaluation can be applied in a broader context, such as inflation forecasting, not just to the models and interval forecasting methods used in this paper.

7. Currency Crashes in Industrial Countries: Much Ado About Nothing?

- Abstract:
- Sharp exchange rate depreciations, or currency crashes, are associated with poor economic outcomes in industrial countries only when they are caused by inflationary macroeconomic policies. Moreover, the poor outcomes are attributable to inflationary policies in general and not the currency crashes in particular. On the other hand, crashes caused by rising unemployment or external deficits have always had good economic consequences with stable or falling inflation rates.

- Abstract:
- We analyze retail prices and at-the-dock (import) prices of speciÖc items in the Bureau of Labor Statisticsí(BLS) CPI and IPP databases, using both databases simultaneously to identify items that are identical in description at the dock and when sold at retail. This identiÖcation allows us to measure the distribution wedge associated with bringing traded goods from the point of entry into the United States to their retail outlet. We Önd that overall U.S. distribution wedges are 50-70%, around 10 to 20 percentage points higher than that reported in the literature. We discuss the implications of this for measuring the size of the "pure" tradeables sector, exchange rate pass-through, and real exchange rate determination. We Önd that distribution wedges are very stable over time but there is considerable variation across items. There is some variation across the country of origin for the imported item, for our major trading partners, but not as much as the cross-item variation. We also investigate the determinants of distribution wedges, Önding that wedges do not vary systematically with exchange rates, but are related to other features of the micro data.

9. Exchange Rates and Fundamentals: A Generalization

- Abstract:
- Exchange rates have raised the ire of economists for more than 20 years. The problem is that few, if any, exchange rate models are known to systematically beat a naive random walk in out of sample forecasts. Engel and West (2005) show that these failures can be explained by the standard-present value model (PVM) because it predicts random walk exchange rate dynamics if the discount factor approaches one and fundamentals have a unit root. This paper generalizes the Engel and West (EW) hypothesis to the larger class of open economy dynamic stochastic general equilibrium (DSGE) models. The EW hypothesis is shown to hold for a canonical open economy DSGE model. We show that all the predictions of the standard-PVM carry over to the DSGE-PVM. The DSGE-PVM also yields an unobserved components (UC) models that we estimate using Bayesian methods and a quarterly Canadian--U.S. sample. Bayesian model evaluation reveals that the data support a UC model that calibrates the discount factor to one implying the Canadian dollar--U.S. dollar exchange rate is a random walk dominated by permanent cross-country monetary and productivity shocks.
