Probability of informed trading on the euro overnight market rate: an update

In this paper the probability of informed trading (PIN) model developed by Easley and O’Hara (1992) is applied to analyze the role and impact of heterogeneities in euro overnight unsecured market. The empirical assessment of the functioning of this market is based on the PIN which measures the ability of traders to interpret signals on the expected evolution of the overnight rate. Results show that between 2000 and 2004 a heterogeneous learning process of market mechanisms within participants could be observed, whereas such asymmetries have been sharply decreasing since 2005. This is reviewed against some significant events that occurred in the euro money market, such as the reform of the Eurosystem’s operational framework in March 2004 and the recent financial market turmoil, which has represented a break in the steady decline of asymmetries as evidence suggest.

The determinants of public deficit volatility

This paper empirically analyzes the political, institutional and economic sources of public deficit volatility. Using the system-GMM estimator for linear dynamic panel data models and a sample of 125 countries analyzed from 1980 to 2006, we show that higher public deficit volatility is typically associated with higher levels of political instability and less democracy. In addition, public deficit volatility tends to be magnified for small countries, in the outcome of hyper-inflation episodes and for countries with a high degree of openness.

US shocks and global exchange rate configurations

The paper analyses the heterogeneity in the link between macroeconomic fundamentals and exchange rates. For a set of important US-specific economic shocks, it shows that such shocks have exerted a remarkably heterogeneous effect on global exchange rate configurations over the past 25 years. Despite a significant decline over time, this heterogeneity remains high as primarily currencies of a few industrialized countries provide the largest contribution to the adjustment of the effective US dollar exchange rate. The paper finds that this heterogeneity is not only due to policy choices of inflexible exchange rate regimes, but to an important extent due to market forces, in particular business cycle synchronization and the degree of financial integration – foremost in portfolio investment – but not to trade. The findings have implications for a potential unwinding of global imbalances and future exchange rate adjustment, as well as for monetary policy choices in emerging market economies.

The Productivity Paradox and the New Economy: The Spanish Case

This paper studies the impact of the information and communication technologies (ICT) on economic growth in Spain using a dynamic general equilibrium approach. Contrary to previous works, we use a production function with six different capital inputs, three of them corresponding to ICT assets. Calibration of the model suggests that the contribution of ICT to Spanish productivity growth is very relevant, whereas the contribution of non-ICT capital has been even negative. Additionally, over the sample period 1995-2002, we find a negative TFP and productivity growth. These results together aim at the hypothesis that the Spanish economy could be placed within the productivity paradox.New economy, information and communication technologies, technological change, productivity paradox.

A persistence-weighted measure of core inflation in the euro area

We propose a new core inflation measure for the Euro area which places the emphasis on the more lasting, i.e. persistent, price developments at a disaggregated level. The importance of each component of the HICP is reweighted according to its relative persistence, as measured by the sum of the autoregressive coefficients or by an indicator of mean reversion. Unlike headline inflation, our baseline core inflation measure is highly correlated with ECB monetary policy decisions, which could mean that it contains ex ante (pre monetary policy) information on inflationary pressure.

Monetary stabilisation in a currency union of small open economies

This paper studies stabilisation policies in a multi-country currency union of small open economies. It abstracts from key factors favouring currency union formation, such as reduced transaction costs and enhanced credibility, which are exogenous to the factors studied here. Demand-side shocks hamper monetary union stabilisation unless members face identical output-inflation tradeoffs and their business cycles are perfectly synchronised. Under supply shocks, welfare implications from joining a currency union are less clear cut. In particular, when these shocks are common across participating countries a tradeoff arises whereby the latter benefit if they are relatively open but are at a disadvantage in case they are of small size. Monetary-fiscal interaction leads to a free rider problem, with area-wide supply shocks eliciting higher interest rate variability. Compared with the case of real wage rigidity, increased real wage flexibility mitigates the free rider problem. Higher trade union decentralisation overall favours a currency union. The present multi-country currency union setup should not be seen as an attempt at settling the sharp differences that exist in the literature. Our model could be modified in order to derive results that are valid in more realistic environments. These include the analysis of public debt considerations in the case of fiscal policies, and both institutional and (further) macroeconomic aspects in the area of wage determination

Hierarchical Markov normal mixture models with applications to financial asset returns

With the aim of constructing predictive distributions for daily returns, we introduce a new Markov normal mixture model in which the components are themselves normal mixtures. We derive the restrictions on the autocovariances and linear representation of integer powers of the time series in terms of the number of components in the mixture and the roots of the Markov process. We use the model prior predictive distribution to study its implications for some interesting functions of returns. We apply the model to construct predictive distributions of daily S&P500 returns, dollarpound returns, and one- and ten-year bonds. We compare the performance of the model with ARCH and stochastic volatility models using predictive likelihoods. The model's performance is about the same as its competitors for the bond returns, better than its competitors for the S&P 500 returns, and much better for the dollar-pound returns. Validation exercises identify some potential improvements. JEL Classification: C53, G12, C11, C14Asset returns, Bayesian, forecasting, MCMC, mixture models

Consumer confidence as a predictor of consumption spending: evidence for the United States and the euro area

For most academics and policy makers, the depth of the 2007-09 financial crisis, its longevity and its impacts on the real economy resulted from an erosion of confidence. This paper proposes to assess empirically the link between consumer sentiment and consumption expenditures for the United States and the euro area. It shows under which circumstances confidence indicators can be a good predictor of household consumption even after controlling for information in economic fundamentals. Overall, the results show that the consumer confidence index can be in certain circumstances a good predictor of consumption. In particular, out-of-sample evidence shows that the contribution of confidence in explaining consumption expenditures increases when household survey indicators feature large changes, so that confidence indicators can have some increasing predictive power during such episodes. Moreover, there is some evidence of a "confidence channel" in the international transmission of shocks, as U.S. confidence indices lead consumer sentiment in the euro area
