The files 'data-cd.xlsx' and 'data-cd.csv' contain the data used in
the empirical application of the paper. They both contain the same data.

- Government spending: this series is the sum of general government
consumption and general government investment. Quarterly data are
available as of 1999Q1, whereas annual data are available beginning in
1981. The quarterly data are retrieved from the ECB's Government
Financial Statistics (GFS).  The annual data, covering the period from
1981 until 1998, are retrieved from the European Commission's AMECO
database. The series is transformed into logs of real per capita
values, as described in Section 3.1 of the paper.

- Real Gross Domestic Product (GDP): this series is published at the
quarterly frequency by the Italian statistical agency (ISTAT). It is
available in seasonally and working days adjusted terms and as of
1981Q4. The series is transformed into logs of real per capita values,
as described in Section 3.1 of the paper.

- Short-term interest rate: this series is the average interest rate
on Italian government T-bills, i.e., government securities with
maturity equal or less than one year. The series is retrieved from the
IMF's International Financial Statistics (IFS). Data are available at
the monthly frequency as of March 1977. We convert the monthly data
into quarterly data prior to estimation.
