In this paper we address the issue of the efficient estimation of the cointegrating vector in linear regression models with variables that follow general (higher order and fractionally) integrated processes.

Brief summaries and user instruction are presented for the programs TRAMO ("Time Series regression with ARIMA Noise, Missing Observations and Outlers") and SEATS ("Signal Extraction in ARIMA Time Series").

Inflation has fallen dramatically in countries like Spain and Italy over the last decade, but the rate of increase in "home good" prices remains stubbornly higher than the rate of increase in "traded good" prices. The paper begins by showing that this discrepancy can be explained (at least in...

The paper deals with estimation of missing observations in possibly nonstationary ARIMA models. First, the model is assumed known, and the structure of the interpolation filter is analysed. Using the inverse or dual autocorrelation function it is seen how estimation of a missing observation is...

The paper contains some implications for applied econometric research. Two important ones are, first, that invertible models, such as AR or VAR models, cannot in general be used to model seasonally adjusted or detrended data. The second one is that to look at the business cycle in detrended...

There is a stark contrast between the recent evolution of labor productivity (and TFP) in the US and EU countries. In the US it accelerated around the mid-1990s and there is evidence of reversion to a high-growth regime. In some EU countries, while employment-population ratios started to rise...

The main focus of this paper is to model the daily series of banknotes in circulation in the context of the liquidity management of the Eurosystem. The series of banknotes in circulation displays very marked seasonal patterns. T o the best of our knowledge the empirical performance of tw o...

This paper reviews some of the applications that use the vast swathes of information provided by Internet user searches for economic analysis and forecasting. This enormous volume of information, available in real time, can be handled by analysts thanks to statistical tools such as “Google...

The Seasonal Adjustment Research Appraisal committee was created in Italy to evaluate procedures for seasonal adjustment of economic series. Because the TRAMO-SEATS programs were one of the main procedures considered, the committee sent a selection of 11 series of interest to be analysed. This...

This paper studies the loss of human capital that emigration generates in the country of origin. To that end I estimate the human capital distribution of emigrants had they not migrated. Unlike previous studies, I take into account the selection of migrants in terms of unobserved characteristics...
