## Δομή της αγοράς και κερδοφορία στους κλάδους της ελληνικής βιομηχανίας με έμφαση στο ρόλο της συγκέντρωσης και των διαφημιστικών δαπανών

##### Resumen

The purpose of this project is to define the factors which determine the
profitability in the branches of the Greek Industry. We will put more emphasis
on the role of concentration and advertising expenditures as well as on their
influence on the earnings. A sample of 90 industrial branches, at a threefigure
level with branches which are brought into action in the processing
industry and which employ more than 10 workers per business, for the period
1993-1996, was used.
In the first part of the project we present in short, the image of the
Greek Industry as well as the problems it faces. Afterwards, the analysis of
the important meanings of this project follows, such as the concentration, the
advertisement, the profitability and the relation between the entry barriers and
the profitability.
In the second part, we refer to some previous studies which were
contacted at an industry level and which tried to define the profitability. These
studies were considered more representative in the way of having used
several explanatory variables of the profitability which are used in this project.
Then, a descriptive statistics of price-cost margin follows, which is the
variable that expresses the profitability at the industrial branches, some other
variables which are used in the research, such as the ratio of advertising
expenditures, the rate of concentration and the minimum effective rate of
production as well as some particular elements which were used for the
construction of variables, such as sales, advertising expenditures, the
employees and the number of shops which function at the particular branches
of industry.
In the fourth -and final- part of this project the results of the econometric
study, which was conducted in the years 1993,1994, 1995 and 1996 at a
cross- sectional level as well as the results which were arisen based on the
study of the industry branches, are presented. Four statistic-economic
packets (MINITAB, SPSS 10.0, Eviews 3.1 and SHAZAM 7.0) were used for
the inferences. The explanatory variables, which were used to define the
profitability, are the ratio of advertising expenditures, the minimum effective
rate of the production, the capital demands, the index of the export effort and the rate of concentration. Our purpose is to see how profitability reacts in
every change in one of these variables.
Several related writings were taken into consideration for the working out of
this diplomatic project. At the end of this essay it is accurately reported where
exactly all the above mentioned are based on.
