The data used in this paper, Encuestas sobre Estrategias Empresariales
(ESEE), are the property of the Fundacion Empresa Publica (FUNEP).  It is
possible to buy the data from the FUNEP at reasonable prices.  Information
about the dataset and how to access the data can be found at the following
web page:

  http://www.funep.es/esee/esee.asp

The raw variables of the ESEE used in this study are:

Name    | Description
codemp  | identification code of the firm
naceclio| industrial classification (18 sectors)
idsit   | status of the firm (ie. Participate or not in the survey)
pbs     | revenues from production
vpv     | firm-level variation of output price between t-1 and t
het     | total effective hours of work
ptm     | number of workers
empidt  | number of workers in R&D activities
ccon    | cost of intermediary consumption
nsea    | cost of external services
vpmp    | firm-level variation of price of material between t-1 and t
vps     | firm-level variation of price of services between t-1 and t
vpe     | firm-level variation of price of energy between t-1 and t
knrbe   | physical capital

Industry-wide deflators for revenues and value added are taken from the
Spanish National Institute of Statistics. They are reported in the two text
files here attached. The first file (rev_deflators) reports the deflators for
revenues (period 1990-1999)m while the second (vadd_deflators) reports the
deflators for value added (period 1990-1997). Note that the first column of
both files lists the identification code of the firm (codemp) so that the
deflators can be immediately linked to the variables of the ESEE.

The two text files, which are in DOS format, are zipped in the file
ornaghi-data.zip. Unix users should use "unzip -a".

The software used for the estimation is the  DPD98  by  Arellano  and  Bond,
which can be downloaded from the web page www.cemfi.es/~arellano/
