Case Study: The Spanish Wine Industry
This scholarly article assesses the elements of competitive advantage in the Spanish wine industry. Strategy, resources, capability, and managerial ability all affect a firm's competitive advantage.
Methodology
Variables
Variables have been grouped into the following
categories, 1) independent: technology, management capabilities,
business strategy, and control variables, 2) dependent: performance.
In
the realm of resources and capabilities, both technological and
managerial capabilities have been analyzed and realized following the
criterion that focuses on both the importance of competitive advantage
and its sustainability.
In the
research process, multi-item five-point Likert scales have been used for
resources and capabilities, strategy and performance.
To measure
resources and capabilities, the scale used is adapted from Ortega
and Spanos and Lioukas. Technological capabilities are evaluated
with four items. Managerial capabilities are analysed using seven
indicators. Both variables are measured with a 5-point Likert scale,
where companies evaluate their position with respect to their
competitors and where the values of the scale are classified from 1
"much weaker than the competitor" to 5 "much stronger than the
competitor". Authors adopted indicators used in other similar studies,
not specific to the wine industry, in order to facilitate the comparison
between sectors, they were previously validated by wine industry
experts.
In strategy, one of the models that has been used to try
to capture the typology of the competitive strategy, is the model
developed by Robinson and Pearce, and it has been used in
different studies. This
model was developed based on previous studies by Dess and Davis,
and aims to expand the generic strategies of Porter, 1980 facilitating
their characterization in empirical business studies.
This
business strategy model consists of 22 indicators assessed with a
5-point Likert scale, where companies evaluate themselves with respect
to different business development efforts, from 1 "is not utilized" to 5
"is primary, constantly utilized".
Following Ortega and
Spanos and Lioukas, the authors have evaluated business
performance with seven indicators grouped into two dimensions: market
position and profitability, in the last three years. The first dimension
shows the external performance of the company, evaluated by its
behavior in the market through four items. The second dimension reflects
the internal performance of the company, the income generated in its
economic activity, through three items. All
the items use a 5-point Likert scale, where companies evaluate their
position with respect to their competitors, and where the values of the
scale are rated from 1 "is much weaker than the competitor" to 5 "is
much stronger than the competitor".
Subjective scales are used
instead of objective scales, due to two reasons. First, the literature
has demonstrated the validity of subjective scales to determine business
performance and their convergent validity with objective scales. Second, accounting data could be
subject to annual variability and may include extraordinary results and
movements outside the main activity of the company. Thus, several studies have used subjective instead of objective
scales to analyze business performance.
