[Analyzing the export potentials of the Portuguese footwear industry with 
Data Envelopment Analysis: When the inefficient are the focus]*

Dimitris Sotiros (Católica Porto Business School and CEGE, Porto, Portugal)


Increasing exports is widely believed to play a central role in economic development 
and firms' profitability, particularly in countries with small domestic markets. With 
that aim, governments and firms spend considerable resources on international 
promotion. Identifying the markets with the greatest potential for export growth is 
therefore crucial for an efficient allocation of public and private resources. In this 
paper, we propose a novel Data Envelopment Analysis (DEA) assessment framework to 
identify trading potentials with existing trading partner countries. We illustrate its 
application with an actual case - the Portuguese footwear industry.
