Determinants of European stock market integration

We analyse the determinants of stock market integration among EU member states for the period 1999–2007. First, we apply bivariate DCC-MGARCH models to extract dynamic conditional correlations between European stock markets, which are then explained by interest rate spreads, exchange rate risk, market capitalisation, and business cycle synchronisation in a pooled OLS model. By grouping the countries into euro area countries, “old” EU member states outside the euro area, and new EU member states, we also evaluate the impact of euro introduction and the European unification process on stock market integration. We find a significant trend toward more stock market integration, which is enhanced by the size of relative and absolute market capitalisation and hindered by foreign exchange risk between old member states and the euro area. Interest rate spreads and business cycle synchronisation are also significant factors in explaining equity market integration.     

COMPETITIVENESS WITHIN THE EURO AREA: THE PROBLEM THAT STILL NEEDS TO BE SOLVED

Unsustainable public debt, low competitiveness and high current account deficits are major problems for the so‐called PIIGS countries. These countries experienced consumer price and wage inflation above the euro area average in the first decade of the euro, basically fuelled by buoyant capital inflows. The resulting real appreciation against low‐inflation countries led to a deterioration in their competitiveness, but rigid labour markets now prevent a quick market‐based readjustment of real wages to the changed situation. Thus, both public expenditure cuts and structural labour market reforms are urgent to reduce the likelihood of a euro area break‐up.     

Exchange rate volatility and growth in small open economies at the EMU periphery

Since the introduction of the euro in January 1999, exchange rate stability in the periphery of the euro area is growing. The paper investigates the impact of exchange rate stability on growth for a sample of 41 mostly small open economies at the EMU periphery. It identifies international trade, international capital flows and macroeconomic stability as important transmission channels from exchange rate stability to more growth. Panel estimations reveal a robust negative relationship between exchange rate volatility and growth for countries in the economic catch-up process with open capital accounts.     

Hungary's entry into the euro area: Lessons for prospective members from a monetary policy perspective

This paper evaluates the conduct of monetary policy in Hungary using standard Taylor rules as well as extended rules that incorporate real exchange rate effects. Moreover, we explicitly consider the impact of future euro area entry by estimating instrument rules that permit an influence from Maastricht Treaty inflation requirements via the estimation of Markov switching models as well as by estimating a differential rule vis-à-vis the existing euro area. Lastly, the paper also considers the impact on policy rules from the large data revision that affects real exchange rate and output estimates. I find that interest rate setting behavior in Hungary does not resemble that of the euro area. Also, counterfactual experiments reveal that the potential macroeconomic costs of entry into the euro area sooner rather than later may be lower than if membership in the single currency area is delayed beyond 2008.     

Equilibrium exchange rates in transition countries: Evidence from dynamic heterogeneous panel models

We use a dynamic heterogeneous panel model to estimate real equilibrium exchange rates for advanced transition countries. Our method is based on out-of-sample estimations from middle-income and high-income countries, and we use a Pooled Mean Group estimator. We find that exchange rates in the Czech Republic, Poland, and Slovakia have converged in recent years with real equilibrium exchange rates expressed in the US dollars. Yet, in 2002, they were overvalued in Hungary but undervalued in Slovenia. We also find that the currencies of the transition countries studied, except Slovenia, were overvalued in 2002 if real effective exchange rates were used. In particular, the Hungarian currency was found to have the largest extent of misalignment.     

Dynamic interactions between Central European currencies and the euro

We argue that the non-euro EU currencies of Central European countries have moved increasingly together with the euro in foreign exchange markets. To prove this point, we examine the dynamics of cross-elasticity between selected Central European currencies (the Czech koruna, Polish zloty, and Hungarian forint) and the euro exchange rates in U.S. dollar terms using daily data for the January 4, 2000 to April 5, 2019 sample period. We adopt the cross-elasticity model originally proposed and tested for the EU currencies by Orlowski (2016). To test the currency co-movements over time, we employ the Bai-Perron multiple breakpoint regression and two-state Markov switching tests. We find evidence of increasing co-movements between the Central European currencies and the euro that become particularly pronounced in times of financial distress. Co-movements of local exchange rates with the euro are also more pronounced during the euro-periphery sovereign debt crisis.     

Internal and external transmissions of monetary and fiscal policies in the EMU

With the introduction of Economic and Monetary Union (EMU), the sovereignty of national monetary institutions has been replaced by a common monetary institution, the European Central Bank (ECB) and national currencies have been replaced by a common currency, the euro. EMU therefore implies the loss of national monetary policy autonomy and internal exchange rate flexibility inside the EMU area. However, external exchange rate adjustment, i.e. adjustment of the euro exchange rate, remains a feasible adjustment mechanism. This paper analyses how internal and external exchange rate flexibility affect macroeconomic adjustment in EMU and non-EMU countries. To do so, a model is constructed in which three countries interact: two countries that decide to form a monetary union and a third country that does not participate in the monetary union. Numerical simulations of a representative example are used to characterise the adjustment dynamics induced by monetary and fiscal policies before and after the start of the EMU.     

The currency denomination of external European Union imports after European Union expansion

Using a multiple market model I examine the impact of euro expansion on the optimal currency denomination of external EU imports. Results suggest euro invoicing will increase more in the EU-expansion country than in the original EU. Exporting firms from dollar bloc countries (the U.S. or countries with fixed exchange rates with the dollar) are more likely to invoice in the euro if price discrimination is already optimal. Firms from outside the dollar bloc are more likely to use the euro when the original EU market is relatively large or transaction costs of exchanging the euro are relatively small.     

Monetary policy rules for convergence to the Euro

This paper investigates the applicability of open-economy convergence-consistent instrument rules for monetary policies in the economies undergoing monetary convergence to a common currency area. The proposed policy rule is forward-looking, consistent with a monetary framework based on inflation-targeting containing input variables that are relative to the corresponding variables in the common currency area. Robust forms of the policy rule are tested empirically for three inflation-targeting countries converging to the euro, i.e. the Czech Republic, Poland and Hungary. Empirical tests imply systemic differences in monetary policies among these euro-candidates. The Czech monetary policy seemingly follows the rule prescribed by our model. Both the Czech and the Polish central bank interest rate policies respond predominantly to changes in the inflation gap, while the Hungarian responds mainly to the exchange rate gap. In all three cases, changes in the eurozone short-term interest rates strongly drive adjustments in the central banks’ reference interest rates.     

MONETARY TRANSMISSION MECHANISM IN CENTRAL AND EASTERN EUROPE: SURVEYING THE SURVEYABLE

Abstract.  This paper surveys recent advances in empirical studies of the monetary transmission mechanism, with special attention to Central and Eastern Europe (CEE). Our results indicate that the strength of the exchange rate pass-through substantially declined over time mainly due to a fall in inflation rates and to some extent due to the so-called composition effect. The asset price channel is weak and is likely to remain weak because of shallow stock and private bond markets and because of low stock and bond holdings of domestic households. House prices may become an exception with booming mortgage lending and with high owner occupancy ratios. While the credit channel could be a powerful channel of monetary transmission – as new funds raised on capital markets are close to zero in CEE – it is actually not, as both commercial banks and non-financial corporations can escape domestic monetary conditions by borrowing from their foreign mother companies. The moderately good news, however, is that those banks and firms are influenced by monetary policy in the euro area because their parent institutions are themselves subjected to the credit channel in the euro area.     

TIME‐VARYING DYNAMICS OF THE REAL EXCHANGE RATE: AN EMPIRICAL ANALYSIS

We use a time‐varying structural vector autoregression to investigate evolving dynamics of the real exchange rate for the UK, euro area and Canada. We show that demand and nominal shocks have a substantially larger impact on the real exchange rate after the mid 1980s. Real exchange rate volatility, relative to fundamentals, also shows a marked increase after this point in time. However, there is some evidence suggesting a closer business cycle co‐movement of the real exchange rate and fundamentals. Simulations from an open‐economy DSGE model show that these results are consistent with a decline in exchange rate pass‐through. Copyright © 2012 John Wiley & Sons, Ltd.     

Stocks,bonds, money markets and exchange rates: measuring international financial transmission

Understanding the complexity of the financial transmission process across various assets—domestically as well as within and across asset classes—requires the simultaneous modeling of the various transmission channels in a single, comprehensive empirical framework. The paper estimates the financial transmission between money, bond and equity markets and exchange rates within and between the USA and the euro area. We find that asset prices react strongest to other domestic asset price shocks, but that there are also substantial international spillovers, both within and across asset classes. The results underline the dominance of US markets as the main driver of global financial markets: US financial markets explain, on average, around 30% of movements in euro area financial markets, whereas euro area markets account only for about 6% of US asset price changes. Moreover, the methodology allows us to identify indirect spillovers through other asset prices, which are found to increase substantially the international transmission of shocks within asset classes.

Pricing‐to‐Market and Market Structure*

Stimulated by imperfect competition/sticky prices framework of the new open economy macroeconomics, empirical research has reconsidered the role of exchange rates in international adjustment. This paper reassesses the link between exchange rates and traded good prices by estimating pricing‐to‐market equations for the five main euro area countries over the period 1990–99. We minimize selection biases by keeping all manufacturing products and all destination markets and show that exchange rate pass‐through (ERPT) is much larger, almost complete, than previously estimated. Thanks to a huge variability in terms of exchange rate variations, products and destination markets, we can map differences in ERPT into market structures and, at the same time, reconcile our results with the empirical literature. We find that ERPT is highly incomplete for sales by oligopolistic industries into advanced economies, indeed in the order of 50–60% as previously estimated. ERPT is instead almost complete in emerging and developing economies where therefore exchange rate movements can help adjust external imbalances. We also find that ERPT is largely asymmetric: it is almost complete after an appreciation of the exporter's currency, rather incomplete after a depreciation. This result is very robust across specifications.     

Nonlinear adjustment,purchasing power parity and the role of nominal exchange rates and prices

Although the literature on purchasing power parity (PPP) is rich in controversy, the relative contribution of prices and nominal exchange rates to real exchange rate movements which restore PPP disequilibria has rarely been put under any close scrutiny. This paper as a first step applies a cointegrated VAR framework to test for stationary real exchange rates and linear adjustments in prices and nominal exchange rates. As a second step, ESTR error correction models are fitted to test whether nonlinear error correctional behaviour characterizes the data. The results clearly indicate that the nominal exchange rate is responsible for the nonlinear mean reverting behaviour in real exchange rates and also mainly drives overall adjustment. Applying dynamic stochastic simulations based on the estimated models, this study also confirms recent results that the half-life times of real exchange rate shocks are significantly smaller than the consensus benchmark of 3–5 years.     

Managed Floating as a Monetary Policy Strategy

Although there seems to be a broad consensus among economists that purely floating or completely fixed exchange rates (the so-called corner solutions) are the only viable alternatives of exchange rate management, many countries do not behave according to this paradigm and adopt a strategy within the broad spectrum of exchange rate regimes that is limited by the two corner solutions. Many of these intermediate regimes are characterized by significant foreign exchange market interventions and a certain degree of exchange rate flexibility with non-preannounced exchange rate targets. While academic research in this area usually concentrates on some specific aspects of intermediate regimes (such as the effectiveness of interventions or institutional aspects), managed floating has rarely been analyzed as a comprehensive monetary policy strategy. In this paper, we present a monetary policy framework in which central banks simultaneously use the exchange rate and the interest rate as operating targets of monetary policy. We explain the mechanics of foreign exchange market interventions and sterilization and we explain why a central bank has an interest of controlling simultaneously the two operating targets. We derive the monetary policy rules for the two operating targets from a simple open economy macro model in which the uncovered interest parity condition and the monetary conditions index play a central role.     

Monetary integration in the Southern Cone

The effect of exchange-rate volatility on the domestic economy depends in part on the importance of trade in total economic activity. Unlike the European Union (EU), trade among the Mercosur countries is less highly integrated, so that movements in intra-area exchange rates are less important than exchange rates vis-à-vis the dollar and the euro. This paper analyzes the impact of exchange-rate and interest-rate volatility on investment and labor markets in the Southern Cone and finds that both volatility against the dollar and the euro and variability of interest rates have significant dampening effects on employment and investment.     

The time series characteristics of quarterly nominal and real lira/pound-sterling exchange rate movements, 1973–1988

Time series analysis is applied to quarterly data on nominal and real, lira/pound-sterling exchange rates for the period 1973 Q1 to 1988 Q2. The paper uses logarithmic values which are examined using both time and frequency domain techniques. Trends and cyclical characteristics are examined and related to the concept of purchasing power parity. Furthermore, the validity of the random walk model is considered, as well as the distribution of exchange rate movements. The results suggest that the nominal exchange rate follows a quasi-random walk with drift, whereas real exchange rates show a quasi-random walk without drift. There exists, however, evidence of a non-stationary mean. The frequency domain techniques do not clearly show that cyclical characteristics are a feature of exchange rate movements. The distribution of these movements shows approximate normality.     

Exchange rate dynamics and their effect on macroeconomic volatility in selected CEE countries

To understand the potential for forming an optimum currency area it is important to investigate the origins of macroeconomic volatility. We focus on the contribution of real exchange rate shocks to macroeconomic volatility in selected Central and Eastern European countries. The contribution of real exchange rate shocks relative to other shocks allows us to evaluate whether the real exchange rate is a source of volatility or a buffer against shocks, as the theory suggests. The identification of the contributions is based on variance decomposition in two-country structural VAR models, which are identified by the sign restriction method. For most of the countries in the sample, shocks are predominantly symmetric relative to their effective counterpart, although the role of non-symmetric shocks is non-negligible. In general, for all the countries considered except Bulgaria and Slovenia, the real exchange rate does not generate large volatility over the business cycle and, with the exception of Bulgaria and Romania, is mostly driven by the non-symmetric shocks. These results are consistent with the real exchange rate having a shock-absorbing nature.     

The impact of macro news and central bank communication on emerging European forex markets

We employ a two-stage empirical strategy to analyze the impact of macroeconomic news and central bank communication on the exchange rates of three Central and Eastern European (CEE) currencies against the euro. First we estimate the nominal equilibrium exchange rate based on a monetary model. Second, we employ a high-frequency GARCH model to estimate the effects of the news and communication along with the estimated exchange rate misalignment on the exchange rate as well as its volatility. The analysis is performed during the pre-crisis (2004–2007) and crisis (2008–2009) periods. CEE currencies react to macroeconomic news during both periods in an intuitive manner that corresponds to exchange rate-related theories. However, the responsiveness of the currencies to central bank verbal interventions becomes important only during the crisis period.     

Do house price developments spillover across euro area countries? Evidence from a global VAR

This paper empirically assesses the prospects for house price spillovers in the euro area, where co-movement in house prices across countries may be particularly relevant given a general trend with monetary union toward increasing linkages in trade, financial markets, and general economic conditions. A global VAR is estimated for three housing demand variables (real house prices, real per capita income, and the cost of borrowing, captured by a real long-term interest rate) on the basis of quarterly data for 7 euro area countries (Belgium, Germany, Ireland, Spain, France, Italy and the Netherlands), which together comprise nearly 90% of euro area GDP, over the period 1971–2009. The results suggest limited house price spillovers in the euro area, albeit with evidence of some overshooting in the first year after the shock, followed by a long run aggregate euro area impact of country-specific changes in real house prices related in part to the country’s economic weight. This contrasts with the impacts of a shock to domestic long-term interest rates, causing a permanent shift in house prices after 2–3 years. Underlying this aggregate development are rather heterogeneous house price spillovers at the country level, with a strong importance for weights – either economic or geographic – in governing their general magnitude. More generally, the impact of financing costs on house prices appears to have grown though time.
