International comovements in inflation rates and country characteristics

Common shocks, similarities in central bank reaction functions, and international trade potentially produce common components in international inflation rates. This paper characterizes such links in international inflation rates with a dynamic latent factor model that decomposes 64 national inflation rates into world, regional, and idiosyncratic components. The world and regional components account for 35% and 16%, respectively, of annual inflation variability on average across countries, so that international influences together explain just over half of inflation variability. The importance of the world and regional components, however, differs substantially across countries. Economic policy choices and development measures strongly explain the cross-sectional variation in the relative importance of international influences. A subsample analysis reveals that the regional (world) factor increases in importance for a number of North American and European (Latin American and Asian) countries since 1980.     

Asymmetric Labor Market Institutions in the EMU and the Volatility of Inflation and Unemployment Differentials

How does the asymmetry of labor market institutions affect the adjustment of a currency union to shocks? To answer this question, this paper sets up a dynamic currency union model with monopolistic competition and sticky prices, hiring frictions, and real wage rigidities. In our analysis, we focus on the differentials in inflation and unemployment between countries, as they directly reflect how the currency union responds to shocks. We highlight the following three results. First, we show that it is important to distinguish between different labor market rigidities as they have opposite effects on inflation and unemployment differentials. Second, we find that asymmetries in labor market structures tend to increase the volatility of both inflation and unemployment differentials. Finally, we show that it is important to take into account the interaction between different types of labor market rigidities. Overall, our results suggest that asymmetries in labor market structures worsen the adjustment of a currency union to shocks.     

Time varying integration of European stock markets and monetary drivers

This study analyzes time-varying integration of stock markets among fourteen European countries and its monetary drivers relevant to the two contrasting events — the introduction of Euro in 1999 and banking crisis of GIIPS in 2011. Our panel analysis reports evidence that monetary performance convergence, lower differentials in interest rates and inflation among EU countries, has been a key driver for the increase in integration of EU stock markets post EMU. Our qualitative analysis indicates that post EMU, the GDP differences among the EU countries have reverse relations with monetary performance convergence. This finding is in line with those of our quantitative study with a price-based indicator for integration.     

Can trade costs explain why exchange rate volatility does not feed into consumer prices?

If countries specialize in imperfectly substitutable goods, trade costs increase the share of expenditure devoted to domestic output, reducing the exposure of consumer price inflation to exchange rate changes. I present a multi-country flexible-price model where expenditure shares are inversely related to trade costs through a gravity equation. In this setting, consumer price inflation can be approximated as an expenditure-share-weighted average of the contributions to inflation from all countries. I use data from 24 OECD countries, 1970-2003, to estimate a structural gravity model. I combine the fitted expenditure shares from the estimation with actual data on exchange rates to construct predictions of inflation. The behavior of these predictions indicates that trade costs can explain both qualitatively and quantitatively the failure of exchange rate volatility to feed into inflation.     

German Wage Moderation and European Imbalances: Feeding the Global VAR with Theory

German labor market reforms in the 1990s and 2000s are generally believed to have driven the large increase in the dispersion of current account balances in the Euro Area. We investigate this hypothesis quantitatively. We develop a three‐region open economy New Keynesian model with search and matching frictions from which we derive robust sign restrictions for wage bargaining and matching efficiency shocks which we term wage moderation shocks. We impose these restrictions on a Global VAR consisting of Germany and eight EMU countries to identify a wage moderation shock in Germany. Our results show that, although the German current account was significantly affected by wage moderation shocks, their contribution to European current account imbalances was negligible. We conclude that the German labor market reforms cannot be the lone driver of European imbalances.     

Saving the Euro: Mitigating Financial or Trade Spillovers?

This paper analyzes through what channels the euro crisis affected firms and the efficacy of policies to mitigate the crisis. It analyzes stock price responses for 3,045 nonfinancial firms in 16 countries to four key policy events during 2010–11. Using precrisis benchmarks, it separates financial effects from trade effects and examines how bank and trade linkages propagated shocks. It finds that policy measures affected financially dependent firms more, particularly in creditor countries with greater bank exposure to peripheral euro countries, in statistically and economically significant ways. Trade linkages with peripheral countries played little role, although euro movements meant some differential effects.     

Inflation targeting and business cycle synchronization

Inflation targeting seems to have a small but positive effect on the synchronization of business cycles; countries that target inflation seem to have cycles that move slightly more closely with foreign cycles. Thus the advent of inflation targeting does not explain the decoupling of global business cycles, for two reasons. Indeed business cycles have not in fact become less synchronized across countries.     

Monetary Policy Stress in EMU: What Role for Fundamentals and Missed Forecasts?

This article reexamines the problem of monetary policy stress in the EMU. In addition to estimating the amount of stress in particular countries, we investigate its sources by breaking it down into its “fundamental” parts, covering how it is a result of country-specific macroeconomic divergences and the EMU-wide “non-fundamental” component, with special attention given to the role of missed forecasts. Our results confirm that peripheral countries were exposed to risks emerging from low interest rates while the “core” countries did not suffer from much monetary policy stress. Interestingly, the bulk of it was non-fundamental, i.e., not caused by inflation and output gap differentials between countries. We show that missed forecasts did make an important contribution to this part of the stress and were mainly responsible for pushing the interest rate below its rule-consistent level.     

Escaping Volatile Inflation

Why has inflation been so stable in developed economies since the early 1990s? In this paper, we answer that the United States and other countries may have escaped from a volatile inflation equilibrium. Our argument builds on the story proposed by Tom Sargent in The Conquest of American Inflation, where the fall in inflation in the 1980s was attributed to changing government beliefs. To explain the escape in inflation volatility, we unwind one of Sargent's simplifications and allow the government to react to some of the shocks in the economy. In this case, when government beliefs turned against the Phillips curve in the 1980s they not only led to an escape from high inflation, but also stopped government using changes in inflation to offset shocks. Inflation and inflation volatility therefore escaped in tandem. Our analysis also sheds some light on why the escape in inflation occurred at the time it did.     

The Euro and inflation uncertainty in the European Monetary Union

This paper adopts a time-varying GARCH framework to estimate short-run and steady-state inflation uncertainty in 12 EMU countries, and then investigates their relationship with inflation. The effects of the Euro introduction in 1999 are examined by utilising a dummy variable. Tests for endogenously determined breaks are also employed. We find a considerable degree of heterogeneity across EMU countries in terms of average inflation, its degree of persistence, and both types of uncertainty, whilst the trend component of inflation is generally decreasing. Various breaks in the relationship between inflation and inflation uncertainty are found, frequently well before the Euro introduction.     

Inflation dynamics: A cross-country investigation

We document that “persistent and lagged” inflation (with respect to output) is a world-wide phenomenon in that these short-run inflation dynamics are highly synchronized across countries. In particular, the average cross-country correlation of inflation is significantly and systematically stronger than that of output, while the cross-country correlation of money growth is essentially zero. We investigate whether standard monetary models driven by monetary shocks are consistent with the empirical facts. We find that neither the new Keynesian sticky-price model nor the sticky-information model can fully explain the data. An independent contribution of the paper is to provide a simple solution technique for solving general equilibrium models with sticky information.     

Systemic and Idiosyncratic Risk in EU-15 Sovereign Yield Spreads after Seven Years of Monetary Union

The market capitalisation of international bond markets is much larger than that of international equity markets. However, compared to the large body of literature on international equity market linkages, there are far fewer empirical studies of bond systemic risk or international bond market co-movements. The extent of international bond market linkages merits investigation, as it may have important implications for the cost of financing fiscal deficit, monetary policymaking independence, modelling and forecasting long-term interest rates, and bond portfolio diversification. In this paper, we investigate the relative influence of systemic and idiosyncratic risk factors on yield spreads over 10-year German government securities during the seven years after the beginning of Monetary Integration. We estimate both panel regressions for the two groups of EU-15 countries (EMU and non-EMU) and specific-country regressions for the nine countries in the EMU group and the three countries in the non-EMU group. All estimations include both domestic (differences in market liquidity and credit risk) and international risk factors. The results present clear evidence that it was mostly idiosyncratic rather than systemic risk factors that drove the evolution of 10-year yield spread differentials over Germany in all EMU countries during the seven years after the beginning of Monetary Integration. Conversely, in the case of non-EMU countries, adjusted yield spreads (corrected from the foreign exchange factor) are influenced more by systemic risk factors. The fact that these countries do not share a common Monetary Policy might explain these results, which may show that government bonds from EMU countries have a better safe-haven status that those of non-EMU countries.     

Stochastic intramarginal interventions in target zones

In this paper, we develop an exchange rate target zone model with stochastic intramarginal interventions that generalizes Krugman's standard model. We assume that money supply changes are (negative) proportional to the velocity shocks. The model produces realistic patterns for the relationship among exchange rate, fundamentals and interest rate differentials, which can explain some empirical failures of previous target zone models. The main result derived from the model is that non-linearities in the behavior of both exchange rate and interest rate differential disappear as intramarginal interventions increase.     

The reset inflation puzzle and the heterogeneity in price stickiness

New Keynesian models have been criticised on the grounds that they require implausibly large price shocks to explain inflation. Bils et al. (2012) show that, while these shocks are needed to reduce the excessive inflation persistence generated by the models, they give rise to unrealistically volatile reset price inflation. This paper shows that introducing heterogeneity in price stickiness in the models overcomes these criticisms directed at them. The incorporation of heterogeneity in price stickiness reduces the need for large price shocks. With smaller price shocks, the new model comes close to matching the data on reset inflation.     

What causes exchange rate volatility? Evidence from selected EMU members and candidates for EMU membership countries

We allow for monetary, real, and financial variables to assess the relevant importance of each of the variables to exchange rate volatility in the case of selected EMU members and candidate countries. Ex-ante analysis shows that volatility in the Polish zloty/euro and the Hungarian forint/euro forex markets can be influenced by the monetary-side of the economy. On the other hand, ex-post analysis shows that forex markets in France, Italy and Spain had been influenced, during the pre-EMU era, by monetary and real shocks. However, the Irish pound exchange rate per ECU had been affected by only real shocks.     

Long-term foreign exchange risk premia and inflation risk

As highlighted by recent literature, long-term foreign exchange risk premia (FRP) of a currency pair tend to covary negatively with short-term real interest rate differentials (RIRD) of the pair. We fit an affine term structure model for 9 major currencies against the US dollar and estimate two components of this covariance: the real risk premia (RRP) component and the inflation risk premia differential (IRPD) component. We find that the IRPD component is significantly negative for all currency pairs in our sample. We propose a macro-finance model to understand the types of shocks that generate such covariance.     

Trade Openness and Exchange Rate Regimes

The paper evaluates the net welfare gains of inflation targeting over a fixed exchange rate as a function of a country's trade openness, using a multisectoral structural model calibrated to Chile. For most calibrations with separable preferences, net welfare gains are increasing in trade openness. The reason is that in more open economies terms of trade shocks, which favor inflation targeting, become quantitatively more important, while price markup shocks in the imperfectly competitive nontradables sector, which favor exchange rate targeting, become less important. The most important exception is heavily indebted countries, where net welfare gains are decreasing in trade openness.     

Exchange Rate Changes and Inflation in Post‐Crisis Asian Economies: Vector Autoregression Analysis of the Exchange Rate Pass‐Through

Macro‐economic consequences of large currency depreciations among the crisis‐hit Asian economies varied from one country to another. Inflation did not soar after the Asian currency crisis of 1997–98 in most crisis‐hit countries except Indonesia where high inflation followed a very large nominal depreciation of the rupiah. The high inflation meant a loss of price competitive advantage, a key for economic recovery from a crisis. This paper examines the pass‐through effects of exchange rate changes on the domestic prices in the East Asian economies using a vector autoregression analysis. The main results are as follows: (i) the degree of exchange rate pass‐through to import prices was quite high in the crisis‐hit economies; (ii) the pass‐through to Consumer Price Index (CPI) was generally low, with a notable exception of Indonesia; and (iii) in Indonesia, both the impulse response of monetary policy variables to exchange rate shocks and that of CPI to monetary policy shocks were positive, large, and statistically significant. Thus, Indonesia's accommodative monetary policy, coupled with the high degree of CPI responsiveness to exchange rate changes was an important factor in the inflation‐depreciation spiral in the wake of the currency crisis.     

Capital inflows and asset prices: Evidence from emerging Asia

The withdrawal of foreign capital from emerging countries at the height of the recent financial crisis and its quick return sparked a debate about the impact of capital flow surges on asset markets. This paper addresses the response of property prices to an inflow of foreign capital. For that purpose we estimate a panel VAR on a set of Asian emerging market economies, for which the waves of inflows were particularly pronounced, and identify capital inflow shocks based on sign restrictions. Our results suggest that capital inflow shocks have a significant effect on the appreciation of house prices and equity prices. Capital inflow shocks account for – roughly – twice the portion of overall house price changes they explain in OECD countries. We also address cross-country differences in the house price responses to shocks, which are most likely due to differences in the monetary policy response to capital inflows.     

Exchange market pressures during the financial crisis: A Bayesian model averaging evidence

In this paper, we examine whether pre-crisis leading indicators help explain pressures on the exchange rate (and its volatility) during the global financial crisis. We use a unique data set that covers 149 countries and 58 indicators, and estimation techniques that are robust to model uncertainty. Our results are threefold: First and foremost, we find that price stability plays a pivotal role as a determinant of exchange rate pressures. More specifically, the currencies of countries that experienced higher inflation prior to the crisis tend to be more affected in times of stress. Second, we investigate potential effects that vary with the level of pre-crisis inflation. In this vein, our results reveal that an increase in domestic savings reduces the severity of pressures in countries that experienced a low-inflation environment prior to the crisis. Finally, we find evidence of the mitigating effects of international reserves on the volatility of exchange rate pressures.
