The Importance of Stock Market Returns in Estimated Monetary Policy Rules: a Structural Approach

This paper estimates a standard version of the New Keynesian Monetary (NKM) model augmented with financial variables in order to analyze the relative importance of stock market returns and term spread in the estimated U.S. monetary policy rule. The estimation procedure implemented is a classical structural method based on the indirect inference principle. The empirical results show that the Fed seems to respond to the macroeconomic outlook and to the stock market return but does not seem to respond to the term spread. Moreover, policy inertia and persistent policy shocks are also significant features of the estimated policy rule.

Does the Term Spread play a role in the FED's reaction function? An Empirical Investigation

Using US data for the period 1967:5-2002:4, this paper empirically investigates the performance of a Fed’s reaction function (FRF) that (i) allows for the presence of switching regimes, (ii) considers the long-short term spread in addition to the typical variables, (iii) uses an alternative monthly indicator of general economic activity suggested by Stock and Watson (1999), and (iv) considers interest rate smoothing. The estimation results show the existence of three switching regimes, two characterized by low volatility and the remaining regime by high volatility. Moreover, the scale of the responses of the Federal funds rate to movements in the rate of inflation and the economic activity index depends on the regime. The estimation results also show robust empirical evidence that the importance of the term spread in the FRF has increased over the sample period and the FRF has been more stable during the term of office of Chairman Greenspan than in the pre-Greenspan period.

Markov Switching Risk Premium and the term structure of interest rates. Empirical evidence from US post-war interest rates

This paper considers the basic present value model of interest rates under rational expectations with two additional features. First, following McCallum (1994), the model assumes a policy reaction function where changes in the short-term interest rate are determined by the long-short spread. Second, the short-term interest rate and the risk premium processes are characterized by a Markov regime-switching model. Using US post-war interest rate data, this paper finds evidence that a two-regime switching model fits the data better than the basic model. The estimation results also show the presence of two alternative states displaying quite different features.

The changing behaviour of the term structure of post-war US

Using U.S. interest rate data covering the period 1950:1-1992:7, this paper tests the rational expectations model of the term structure of interest rates. We show evidence that the rational expectations model of the term structure is supported by the data during the seventies and a period lasting from the mid-eighties to the end of the sample. However, during the …fties, sixties and a period that covers most of the Volcker’s office term (from September 1979 to April 1986) the term structure model is rejected by the data. Moreover, wefind evidence of regime changes in the short-term rate process and the term structure of interest rates. These regime switches roughly coincide with changes in the Federal Reserve chairman. The switches in monetary policy taking place when the chairmanship of the Federal Reserve changes therefore seem to play an important role in characterizing the term structure of interest rates.

Is there a Phillips Curve in the US and the EU15 Countries? An empirical investigation

This paper studies the comovement between output and inflation in the EU15 countries. Following den Haan (2000), I use the correlations of VAR forecast errors at different horizons in order to analyze the output-inflation relationship. The empirical results show that eight countries display a significant positive comovement between output and inflation. Moreover, the empirical evidence suggests that a Phillips curve phenomenom is more likely to be detected in countries where inflation is more stable.

The role of the term spread in an augmented Taylor rule: An empirical investigation

Using US data for the period 1967:5-2002:4, this paper empirically investigates the performance of an augmented version of the Taylor rule (ATR) that (i) allows for the presence of switching regimes, (ii) considers the long-short term spread in addition to the typical variables, (iii) uses an alternative monthly indicator of general economic activity suggested by Stock and Watson (1999), and (iv) considers interest rate smoothing. The estimation results show the existence of switching regimes, one characterized by low volatility and the other by high volatility. Moreover, the scale of the responses of the Federal funds rate to movements in the term spread, inflation and the economic activity index depend on the regime. The estimation results also show robust empirical evidence that the ATR has been more stable during the term of office of Chairman Greenspan than in the pre-Greenspan period. However, a closer look at the Greenspan period shows the existence of two alternative regimes and that the response of the Fed funds rate to inflation has not been significant during this period once the term spread is considered.

Factores explicativos del éxito competitivo. Un estudio empírico en la pyme

[ES] Identificar el origen de la competitividad, a pesar de ser un tema controvertido, es algo a lo que investigadores, consultores y directivos dedican grandes esfuerzos. El hecho de que la mayoría de los estudios dirijan su atención hacia niveles macroeconómicos o se centren en la gran empresa nos lleva en este trabajo a identificar, basándonos en la literatura, los factores de éxito competitivo específicos de las pyme. A continuación, tras analizar cómo medir el éxito competitivo, se realiza un estudio empírico con una muestra de 473 pyme de la Región de Murcia para determinar cuáles son los factores explicativos de su éxito. Los resultados del estudio confirman parcialmente los recogidos en la literatura. Del trabajo se extraen interesantes conclusiones tanto relativas a cuáles son los factores explicativos del éxito en las pyme como de cara a la realización de nuevas investigaciones sobre este tema.

¿Reflejan los índices de riesgo país las variables relevantes en el desencadenamiento de las crisis externas? Un análisis sobre el periodo 1994-2001

[ES] El objetivo de este trabajo es establecer en qué medida los índices de riesgo país más utilizados por la comunidad económica y financiera internacional, en concreto, el índice de Euromoney y el ICRG, recogen las variables relevantes en el desencadenamiento de las crisis monetarias y financieras externas, como un aspecto básico en la evaluación de su capacidad para medir adecuadamente el riesgo de los diferentes países.

La elección de la marca del distribuidor en productos duraderos: factores de influencia

[ES] La apuesta de la distribución por la extensión de su marca a las categorías de productos duraderos, como electrodomésticos y productos electrónicos para el hogar, ha demostrado ser acertada, a pesar de las críticas en contra de esta estrategia. Posiblemente, la mayor familiaridad del consumidor con las marcas del distribuidor, el cambio de actitud favorable hacia éstas, la disponibilidad de la tecnología, y por qué no, la crisis económica internacional que afecta a las economías domésticas, pueden ser factores explicativos de este éxito.
