Inflation Targeting and Debt: Lessons from Brazil

Studying the recent experience of Brazil the paper explains how default risk is at the centre of the mechanism through which an emerging market central bank that targets inflation might lose control of inflation--in other words of the mechanism through which the economy might move from a regime of 'monetary dominance' to one of 'fiscal dominance'. The literature, from Sargent and Wallace (1981) to the modern fiscal theory of the price level has discussed how an unsustainable fiscal policy may hinder the effectiveness of monetary policy, to the point that an increase in interest rates can have a perverse effect on inflation. We show that the presence of default risk reinforces the possibility that a vicious circle might arise, making the fiscal constraint on monetary policy more stringent.

Financial Factors, Macroeconomic Information and the Expectations Theory of the Term Structure of Interest Rates

In this paper we concentrate on the hypothesis that the empirical rejections of the Expectations Theory(ET) of the term structure of interest rates can be caused by improper modelling of expectations. Our starting point is an interesting anomaly found by Campbell-Shiller(1987), when by taking a VAR approach they abandon limited information approach to test the ET, in which realized returns are taken as a proxy for expected returns. We use financial factors and macroeconomic information to construct a test of the theory based on simulating investors' effort to use the model in `real time' to forecast future monetary policy rates. Our findings suggest that the importance of fluctuations of risk premia in explaining the deviation from the ET is reduced when some forecasting model for short-term rates is adopted and a proper evaluation of uncertainty associated to policy rates forecast is consideredExpectations Theory, Macroeconomic information in Finance

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.

Euro area money demand and international portfolio allocation: a contribution to assessing risks to price stability

The long-run relationship between money and prices in the euro area embedded in traditional money demand models with income and interest rates broke down after 2001. We develop a money demand model where investors hold a diversified portfolio with money, domestic and foreign stocks and long-term bonds in which, in addition to the classical wealth effect, also a size and an international portfolio allocation effects arise. The estimated model identifies three cointegrating vectors stable over the sample 1980-2007: a long-run money demand, which depends on income and all risky assets' returns, and two equilibria for the euro area and the US financial markets. Steady state equilibrium of nominal M3 growth is estimated to be about 7% in 2007 with large standard errors mainly due to uncertainty in asset prices. The gap between actual euro area M3 growth and model-based fitted or predicted values helps forecast euro area inflation.

Insider Trading, Traded Volume and Returns

Several models predict that both market liquidity and trading volume generated by less informed traders do not increase when there is insider trading. Available empirical evidence is mixed and still relatively small, because of the inherent di¢ culty to identify insider trading events. Our econometric work, based on 19 suspect insider trading events drawn from the non-public ?file of the Italian supervisory authority, provides further insight on these key implications of stock market models. The second purpose of this paper is to assess whether insider trading changes the distribution of volume and returns in a way that can be used by supervisory authorities in order to detect its presence through statistical methods.asymmetric information, insider trading, abnormal returns, traded volume

Looking for Contagion: Evidence from the ERM

This paper applies a full-information technique to test for the presence of contagion across the money markets of ERM member countries. We show that whenever it is possible to estimate a model for interdependence, a test for contagion based on a full information technique is more powerful. We test for the presence of contagion after having identified episodes of country-specific shocks, whose effects on other European markets are significantly different from those predictable from the estimated channels of interdependence. Using data on three-months interest rate spreads on German rates for seven countries over the period 1988-1992, we are unable to reject the null of contagion. Our evidence suggest that contagion within the ERM was a general phenomenon, not limited to a subset of weaker countries, the exception in the sample being France. Our results are mute as to the question of what lies behind these episodes of contagion; they show, however, that it is not always true that one only detects contagion when one applies poor statistical techniques.

On the statistical identification of DSGE models

Dynamic Stochastic General Equilibrium (DSGE) models are now considered attractive by the profession not only from the theoretical perspective but also from an empirical standpoint. As a consequence of this development, methods for diagnosing the fit of these models are being proposed and implemented. In this article we illustrate how the concept of statistical identification, that was introduced and used by Spanos [Spanos, Aris, 1990. The simultaneous-equations model revisited: Statistical adequacy and identification. Journal of Econometrics 44, 87–105] to criticize traditional evaluation methods of Cowles Commission models, could be relevant for DSGE models. We conclude that the recently proposed model evaluation method, based on the DSGE−VAR(λ), might not satisfy the condition for statistical identification. However, our application also shows that the adoption of a FAVAR as a statistically identified benchmark leaves unaltered the support of the data for the DSGE model and that a DSGE-FAVAR can be an optimal forecasting model

Implications of return predictability for consumption dynamics and asset pricing

Two broad classes of consumption dynamics—long-run risks and rare disasters—have proven successful in explaining the equity premium puzzle when used in conjunction with recursive preferences. We show that bounds a-là Gallant, Hansen, and Tauchen that restrict the volatility of the stochastic discount factor by conditioning on a set of return predictors constitute a useful tool to discriminate between these alternative dynamics. In particular, we document that models that rely on rare disasters meet comfortably the bounds independently of the forecasting horizon and the asset returns used to construct the bounds. However, the specific nature of disasters is a relevant characteristic at the 1-year horizon: disasters that unfold over multiple years are more successful in meeting the predictors-based bounds than one-period disasters. Instead, at the 5-year horizon, the sole presence of disasters—even if one-period and permanent—is sufficient for the model to satisfy the bounds. Finally, the bounds point to multiple volatility components in consumption as a promising dimension for long-run risk models
