Yield spreads on EMU government bonds

We provide evidence that the movements in yield differentials between euro zone government bonds explained by changes in international risk factors – as measured by banking and corporate risk premiums in the United States – are more pronounced for bonds issued by Italy and Spain. Liquidity factors play a smaller role, so policies meant to increase financial market efficiency do not appear sufficient to deliver a ‘seamless’ bond market in the euro area. The risk of default is a small but important component of yield differentials movements, which signal market perceptions of fiscal vulnerability, impose market discipline on national fiscal policies, and may be reduced only by further convergence in debt ratios.

Immediate challenges for the European Central Bank

This paper discusses a number of issues that the newly constituted Board of the ECB will face early on. We show how conducting a European monetary policy is very different from living under the protective umbrella of the Bundesbank. We discuss voting on the ECB Board and argue that the ability to communicate to the public will be a critical factor for the success of the new institution. We also ask how a single monetary policy -- a common change in the interest rate controlled by the ECB -- is transmitted to the economy of the member countries. We show that the monetary process differs significantly inside EMU: initially disinflation episode could thus fall very unequally on a few member countries because they have a combination of financial structure that spreads a monetary contraction widely structure that is relatively inflexible. This process, moreover, is sure to evolve of the financial industry restructuring that is already underway and will be accentuated by the common money. Furthermore, as the Lucas principle suggests, the wage-price process itself will adapt to the changing focus of European monetary policy.

Measuring Monetary Policy with VAR Models: An Evaluation

This paper evaluates VAR models designed to analyse the monetary policy transmission mechanism in the United States by considering three issues: specification, identification, and the effect of the omission of the long-term interest rate. Specification analysis suggests that only VAR models estimated on a single monetary regime feature parameter stability and do not show signs of mis-specification. The identification analysis shows that VAR-based monetary policy shocks and policy disturbances identified from alternative sources are not highly correlated but yield similar descriptions of the monetary transmission mechanism. Lastly, the inclusion of the long-term interest rate in a benchmark VAR delivers a more precise estimation of the structural parameters capturing behaviour in the market for reserves and shows that contemporaneous fluctuations in long-term interest rates are an important determinant of the monetary authority’s reaction function.

Is the international propagation of financial shocks non-linear?: Evidence from the ERM

Abstract This paper tests for the presence of non-linearities in the propagation of devaluation expectations among the countries that were members of the Exchange Rate Mechanism of the EMS. We show that whenever it is possible to estimate a model for financial interdependence, a full-information technique to detect such non-linearities is more efficient than the limited-information estimator proposed, in a similar context, by Rigobon (2000) . This happens, in particular, when the periods of market turbulence are relatively short. Our evidence suggests that non-linearities in the propagation of devaluation expectations were a general phenomenon in the ERM. Normally the non-linearity amounts to a stronger effect in the same direction, but sometimes, as in the Dutch case, it implies a significant effect in the opposite direction: evidence of flight-to-quality.

How Does Liquidity Affect Government Bond Yields

The paper explores the determinants of yield differentials between sovereign bonds, using Euro area data. There is a common trend in yield differentials, which is correlated with a measure of aggregate risk. In contrast, liquidity differentials display sizeable heterogeneity and no common factor. We propose a simple model with endogenous liquidity demand, where a bonds liquidity premium depends both on its transaction cost and on investment opportunities. The model predicts that yield differentials should increase in both liquidity and risk, with an interaction term of the opposite sign. Testing these predictions on daily data, we find that the aggregate risk factor is consistently priced, liquidity differentials are priced for a subset of countries, and their interaction with the risk factor is in line with the models prediction and crucial to detect their effect.

Testing The Lucas Critique: A Review

Claims that the parameters of an econometric model are invariant under changes in either policy rules or expectations processes entail super exogeneity and encompassing implications. Super exogeneity is always potentially refutable, and when both implications are involved, the Lucas critique is also refutable. We review the methodological background; the applicability of the Lucas critique; super exogeneity tests; the encompassing implications of feedback and feedforward models; and the role of incomplete information. The approach is applied to money demand in the u.S.A. to examine constancy, exogeneity, and encompassing, and reveals the Lucas critique to be inapplicable to the model under analysis.

Macroeconomic Stability and the Preferences of the Fed. A Formal Analysis, 1961-98

The rate of inflation in the U.S. has declined from an average of 4.5% in the period 1960-79 to an average of 3.6% in 1980-98. Between those two periods, the standard deviations of inflation and the output gap have also declined. These facts can be attributed to the interaction of three possible factors: a shift in central bank preferences, a reduction in the variability of aggregate supply shocks, and a more efficient conduct of monetary policy. In this paper we identify the relative roles of these factors. Our framework is based on the estimation of a small structural macro model for the U.S. economy jointly with the first order conditions, which solve the intertemporal optimization problem faced by the Fed. Overall, our results indicate that the policy preferences of the Fed, and in particular the (implicit) inflation target, have changed drastically with the advent of the Volcker-Greenspan era. In addition, we find that the variance of supply shocks has been lower and monetary policy has been conducted more efficiently during this period.

High Yields: The Spread on German Interest Rates

This paper is a first attempt at evaluating the determinants of the total interest rate differentials on government bonds between high yielders, namely Spain, Italy, Sweden, and Germany. In particular, we address the question of the relative importance of local and global factors in the determination of such spreads. We identify and measure two components of total yield differentials: one due to expectations of exchange rate depreciation, which we call the exchange rate factor; and another which reflects the market assessment of default risk. We propose and discuss a measure of the exchange rate factors and of the default risk premium based on interest rates swaps. Overall our investigation provides strong evidence in favour of the existence of a common trend for the Spanish and Italian spreads on Bunds, which is not shared by the Swedish spread. Such trend is driven by international factors and is independent from country-specific shocks. Country-specific shocks are only relevant in explaining short-term cycles around the common stochastic trend.

Sovereign spreads in the eurozone: which prospects for a Eurobond?

In this paper, we provide new evidence on the determinants of sovereign yield spreads and contagion effects in the euro area in order to evaluate the rationale for a common Eurobond jointly guaranteed by euro-area Member States. We find that default risk is the main driver of yield spreads, suggesting small gains from greater liquidity. Fiscal fundamentals matter in the pricing of default risk but only as they interact with other countries’ yield spreads; i.e. with the global risk that the market perceives. More important, the impact of this global risk variable is not constant over time, a clear sign of contagion driven by shifts in market sentiment. This evidence points to a discontinuity in the disciplinary role of financial markets. If markets can stay irrational longer than a country can stay solvent, then the role of yield spreads on national bonds as a fiscal discipline device is considerably weakened, and issuing Eurobonds can be economically justified.

The Transmission Mechanism of Monetary Policy in Europe: Evidence from Banks' Balance Sheets

Available studies on asymmetries in the monetary transmission mechanism within Europe are invariably based on macro-economic evidence: such evidence is abundant but often contradictory. This paper takes a different route by using micro-economic data. We use the information contained in the balance sheets of individual banks (available from the BankScope database) to implement a case-study on the response of banks in France, Germany, Italy and Spain to a monetary tightening. The episode we study occurred during 1992, when monetary conditions were tightened throughout Europe. Evidence on such tightening is provided by the uniform squeeze in liquidity, which affected all banks in our sample. We study the first link in the transmission chain by analysing the response of bank loans to the monetary tightening. Our experiment provides evidence on the importance of the Europe and thus on one possibly important source of asymmetries in the monetary transmission mechanism. We do not find evidence of a significant response of bank loans to the monetary tightening, which occurred during 1992, in any of the four European countries we have considered. However we find significant differences both across countries and across banks of different dimensions in the factors that allow them to shield the supply of loans from the squeeze in liquidity.
