Inflation Persistence during Periods of Structural Change: An Assessment Using Greek Data

The paper estimates inflation persistence in Greece from 1975 to 2003, a period of high variation in inflation and changes in policy regimes. Three empirical methodologies, univariate autoregressive (AR) modelling, second-generation random coefficient (RC) modelling, and vector autoregressive (VAR) modelling, are employed to estimate inflation persistence. The empirical results from all the procedures suggest that inflation persistence was high during the inflationary period and the first six years of the disinflationary period, while it started to decline after 1997, when inflationary expectations seem to have been stabilised, and thus, monetary policy was effective at reducing inflation. Empirical findings also detect a sluggish response of inflation to changes in monetary policy. This observed delay seems to have changed little over time.CPI inflation; persistence; structural change

DEMOGRAPHIC TRANSITION IN EUROPE

Using panel cointegration analysis, we show that a cointegration relationship exists among fertility choice, infant mortality, real wages and real per capita output. The results suggest that in low mortality economies reductions in infant mortality will decrease fertility.

Measuring the Correlation of Shocks betweem the EU15 and the New Member Countries

This paper considers the question of the symmetry of inflation, exchange rate changes and GDP shocks between the EU15 and the new member countries. It applies a relatively new technique, the orthogonal GARCH model, which allows us to calculate a complete time varying correlation matrix for these countries. We can then examine the way the conditional correlation of shocks between the EU15 and the new member countries has been evolving over time. Our results suggest that the shocks which hit the EU are not symmetrical with those affecting the majority of new member countries. In addition, most of the new member countries seem to exhibit relatively low correlation with EU15.Business cycle, GARCH

The New Keynesian Phillips Curve and Lagged Inflation: A Case of Spurious Correlation?

The New Keynesian Phillips Curve (NKPC) specifies a relationship between inflation and a forcing variable and the current period’s expectation of future inflation. Most empirical estimates of the NKPC, typically based on Generalized Method of Moments (GMM) estimation, have found a significant role for lagged inflation, producing a “hybrid” NKPC. Using U.S. quarterly data, this paper examines whether the role of lagged inflation in the NKPC might be due to the spurious outcome of specification biases. Like previous investigators, we employ GMM estimation and, like those investigators, we find a significant effect for lagged inflation. We also use time varying coefficient (TVC) estimation, a procedure that allows us to directly confront specification biases and spurious relationships. Using three separate measures of expected inflation, we find strong support for the view that, under TVC estimation, the coefficient on expected inflation is near unity and that the role of lagged inflation in the NKPC is spurious.New Keynesian Phillips curve; time-varying coefficients; spurious relationships.

Fertility Determinants and Economic Uncertainty:An Assessment Using European Panel Data

This paper examines the determinants of fertility, using panel data for twenty-seven European countries. We employ panel co-integration to estimate fertility as function of demographic and economic variables. We show that low fertility in most industrialized countries in Europe is due to low infant mortality rates, high female employment, low nuptiality rate and high opportunity cost of having children. Using two measures of economic uncertainty, which are associated with labor market decisions - a production (an output) volatility measure and the unemployment rate - we examine to what extent economic insecurities affect fertility decisions. The empirical results show that both measures of economic uncertainty have a significant negative impact on fertility implying that labor market insecurities might be a significant factor affecting fertility decisions.Fertility Choice; Panel Estimation

Bretton-Woods systems, old and new, and the rotation of exchange-rate regimes

A recent contribution to the literature argues that the present international monetary system in many ways operates like the Bretton-Woods system. Asia is the new periphery of the system and pursues an export-led development strategy based on undervalued exchange rates and accumulated foreign reserves. The United States remains the centre country, pursuing a monetary-policy strategy that overlooks the exchange rate. Under both regimes the United States does not take external factors into account in conducting monetary policy while the periphery does take external factors into account. We provide results of a test of this hypothesis. Then, we present a new method for decomposition of a seasonally adjusted series the business cycle and other components using a time-varying-coefficient technique that allows us to test the relationship between the cycle and macroeconomic policies under both regimes.Revived Bretton-Woods system, asymmetry hypothesis, time-series, decomposition, time-varying-coefficient estimation

Bretton-Woods Systems, Old and New, and the Rotation of Exchange-Rates Regimes

A recent contribution to the literature argues that the present international monetary system in many ways operates like the Bretton-Woods system. Asia is the new periphery of the system and pursues an export-led development strategy. The members of the new periphery peg their currencies to the U.S. dollar at undervalued exchange rates and accumulate foreign reserves. In contrast, the old periphery - - consisting of Western Europe, Canada and parts of Latin America - - interacts with the centre with flexible exchange rates; its aggregate current account has been roughly in balance. As under the older system, the United States remains the centre country, pursuing a monetary-policy strategy that overlooks the exchange rate. An implication of this argument is the following asymmetry hypothesis: under both regimes the United States does not take external factors into account in conducting monetary policy while the periphery does take external factors into account. We provide results of a test of the asymmetry hypothesis. Then, we present a new method for decomposition of the business cycle using a time-varying-coefficient technique that allows us to test the relationship between the cycle and macroeconomic policies. We apply this technique to five countries for three sub-periods over the 1959 to 2007 period.Revived Bretton-Woods System; Asymmetry Hypothesis; Time-Series Decomposition; Time-Varying-Coefficient Estimation

Some Further Evidence on Exchange-Rate Volatility and Exports

The relationship between exchange-rate volatility and aggregate export volumes for 12 industrial economies is examined using a model that includes real export earnings of oil-producing economies as a determinant of industrial-country export volumes. A supposition underlying the model is that, given their levels of economic development, oil-exporters’ income elasticities of demand for industrial-country exports might differ from those of industrial countries. Five estimation techniques, including a generalized method of moments (GMM) and random coefficient (RC) estimation, are employed on panel data covering the estimation period 1977:1-2003:4 using three measures of volatility. In contrast to recent studies employing panel data, we do not find a single instance in which volatility has a negative and significant impact on trade.Exchange-rate volatility; Trade; Random-coefficient estimation; Generalized method of moments; Panel

Assessing the Casual Relationship between Euro-Area Money and Price in Time-Varying Environment

The paper provides new evidence on the causal relationship between money and price for the euro area using quarterly data for the period 1980 to 2006, employing two alternative methods of estimation: the vector error correction (VEC) and time-varying coefficient (TVC) estimation techniques. The latter technique has the advantage over the former technique in that it can deal with possible specification biases and spurious relationships that may have arisen from structural changes. The empirical results from the VEC method reveal a bidirectional causal relationship between money and price. Contrary, the results from the TVC technique suggest that money is acting as an exogenous process determining the price level.Causality; VEC, Time Varying Coefficient Estimation; Euro Area
