In the previous sections we’ve analyzed the credit rationing theory and
concentration process taking as main frame the Argentinean case, in this section and the
following ones the work will try to show the empirical evidence found connecting the
credit rationing with the SMEs financing problems but highlighting the importance of
the asymmetric information related with the size of financial entities.
The sequence of relations would be interpreted as:

• CONCENTRATION  → SMALL BANK DECREASE IN NUMBERS

→ b) ASYMMETRIC INFORMATION INCREASE → TRANSACTIONAL COST INCREASE (ECONOMIES OF SCALE NOT POSSIBLE)
→ c) ADVERSE SELECTION → CREDIT RATIONING

​​

Referential frame: a) bank size b) asymmetric information c) SMEs
