Euro area inflation persistence 总被引:1,自引:1,他引:1
Nicoletta Batini 《Empirical Economics》2006,31(4):977-1002
This paper presents evidence on the lag between monetary policy actions and the response of inflation in the euro area as a whole as well as in some of its core countries, notably Germany, Italy and France. In line with previous findings for the US and the UK, results here show that it takes over a year before monetary policy actions have their maximum effect on inflation both in the euro area and in individual countries and that a lag of this length has existed in Europe at least since the collapse of the Bretton Woods system, despite the numerous changes in European monetary policy regime thereafter. Results based on alternative definitions of inflation persistence support these findings and indicate, if any, that transmission lags could be in fact much longer for individual countries and the euro area as a whole, although, at the country level, there is strong evidence over time of a drop in German inflation persistence and a sizeable shift in the mean of inflation – particularly in Italy and France. An examination based on results from this paper reveals that euro area inflation persistence could well be an intrinsic phenomenon rather than a ‘statistical fluke’ due to aggregation.This research was conducted during my visit at the European Central Bank Directorate Research, as part of the Research Visitor Programme. I would like to thank Anna Maria Agresti for providing individual country data from the macroeconomic database of the Monetary Transmission Network; Alistair Dieppe for providing data from the ECB area-wide model dataset; and Michele Manna for supplying me with the area-wide M3 data for the period 1970–1980. I thank Gabriel Fagan, Frank Smets, Ignazio Angeloni, Vítor Gaspar, Michael Ehrmann, Guenter Coenen, Oreste Tristani, Tommaso Monacelli, Stephanie Schmitt-Grohe and Gerhard Ruenstler for helpful discussions during my stay at the ECB. I would also like to thank seminar participants at the ECB for their input and I am very grateful to Jeffrey Fuhrer, Edward Nelson and Kenneth West, Bernd Fitzenberger and two anonymous referees for comments on an earlier draft. Any errors and omissions are mine. The views expressed in this paper are those of the author and should not be attributed to the International Monetary Fund, its Executive Board, or its management 相似文献

According to the idea of cost control based on the value chain, several important factors are necessary. Firstly, it is necessary to have enough resources, which must be invested to create advantageous value chain based on customer value. It is also necessary to be sure of the cost advantage of the value chain. Secondly, the consumption of resources must be reduced as much as possible to enable the smallest operating cost for the value chain and make sure of the cost advantage based on maximum business value or profit. It is a kind of cost control from the whole view of creation and supply of value. In practice, it is also a kind of cost control system based on the value chain. It includes enough control and necessary resource investment from the view of the value creation, and keeps consumption of resources to a reasonable level from the view of the value supply. The main object of the first factor is to construct the advantageous value chain from creating customer value; and the second factor is to strengthen the advantageous value chain from supplying or producing customer value. Therefore it is a new kind of idea to explore this cost control from the whole view of creation and supply of value. It is more profitable for businesses to gain sustainable competitive advantage. 相似文献

In this study, we introduce progressive taxation and human capital differences across productive sectors into a typical monetary policy game. The objective of this work is to reveal the potential short-run effects of these two typical features of economic growth on inflation dynamics. In our framework, such features act as frictions of labor mobility across sectors. We show that an increased progressivity of taxation lowers the diffusion of shocks, and in turn increases inflation persistence. Moreover, the dispersion of human capital across sectors acts as a barrier to labor mobility and thereby increasing inflation inertia through the same channel. We also empirically verify these findings by employing panel data analysis in a sample of 28 OECD countries. 相似文献

When a Door Closes,a Window Opens? Long‐Term Labor Market Effects of Involuntary Separations 下载免费PDF全文
This study estimates the earning losses of workers experiencing an involuntary job separation. We employ, for the first time in the earning losses literature, a Poisson pseudo‐maximum‐likelihood estimator with fixed effects that has several advantages with respect to conventional fixed effects models. The Poisson estimator allows considering the full set of involuntary separations, including those with zero labor market earnings because of unemployment. By including individuals with zero earnings and by using our new method, the loss in the year of separation becomes larger than in previous studies. The loss starts with roughly 30% and, although it quickly shrinks, it remains at around 15% in the following years. In addition, we find that compared to other reasons for separation, the earning loss pattern is unique for involuntary separations, because no other type of separation implies such permanent scarring. This latter finding makes us confident that the self‐reported involuntariness of a separation is a reliable source of information. 相似文献

The persistence of unemployment increased during the recent great recession in many European countries, although with diversified impacts. We therefore analyse such impacts in four European countries – Italy, Spain, France and the UK – which represent different institutional frameworks and may reflect the so-called continental European and Anglo-Saxon frameworks. We analyse the determinants of unemployment persistence using individual-level data from the European Union Statistics on Income and Living Conditions (EU-SILC) panel for the period 2007–2013. These data enable us to take into account initial conditions and state dependence in addition to individual and household characteristics. We focus on gender and regional effects, which have a strong impact on the persistence in the state of unemployment. We find that gender gap is significant in Italy and the UK, implying that male workers show a higher probability of remaining unemployed. In Italy, such a pattern is due to the worsening of male workers’ conditions during the crisis, whereas in the UK, male workers show higher unemployment rates than women. Regional effects are significant in all countries analysed and underline a relevant structural factor that should be addressed on policy grounds in Europe. Such effects are greater in Spain and Italy. 相似文献

This article examines the dynamic behavior of the inflation rate for eight Asian countries using a quantile unit root test. We advocate a three-way definition of inflation targeting based on perfect, imperfect and zero credibility and advance the analysis by incorporating a fully-fledged adoption of inflation targeting. In doing so, we offer new insights by showing that the credibility of inflation targeting and the alternative monetary policy frameworks in Asia are imperfect, except for Malaysia and South Korea under a fully-fledged adoption of inflation targeting. In contrast to past studies that focus on the mean-reversion in inflation rates, we also consider trend-reversion and find that Asian inflation targeting countries have been building up their monetary policy credibility more than the non- inflation targeting countries in terms of a faster rate of decline in inflation rate changes. Our results generally indicate the presence of mean reversion at the lower quantiles only. Where stationarity is present, we find evidence of a varied speed of adjustment process across the quantiles. Finally, we determine the threshold levels whereby inflation becomes stationary and demonstrate that Asian inflation rates generally display stationary behavior during periods of inflation declining or slowing down. 相似文献

This paper represents a contribution to empirical debate on the persistence of innovation in the firm, by exploiting an innovative panel database that, for the first time, links three waves of the Italian Community Innovation Survey with an administrative data source providing economic and financial information for firms in the Italian manufacturing sector, 1996–2003. By using both a dynamic logistic model and a Granger causality approach, we show that in order to innovate successfully it is much more important to have an adequate flow of profits during an appropriate time span rather than high profits only during one period before innovation. Our causality tests prove the existence of a dynamic interaction between innovation and profitability: successful innovation can, in the short run, generate the profitability conditions that can then enhance the financial resources needed to reinvest in new technological opportunities, thus causing the firm to persist in its innovative behaviour. We have also shown that another important source of persistence is represented by past innovative experience. A firm with consolidated innovative behaviour would have a higher probability of future successful innovation with respect to a firm that occasionally (or accidentally) innovates. Persistence in innovation enables a firm to take advantage of substantial technological and organizational learning effects, which improve with time. 相似文献
