We use Bulgarian firm-level data to investigate the impact of liquidity con
straints on investment performance. Internal funds are an important determi
nant of investment in most industrialized countries. We test whether intern
al funds are important for firm investment during the current transition pr
ocess in Bulgaria. We use a simple accelerator model of investment to test
whether Liquidity constraints are relevant in the case of Bulgaria. Our est
imations are based on data for the period 1993-95, prior to the Bulgarian f
inancial crisis in 1996-97. It turns out that Bulgarian firms are liquidity
constrained, and that firms' size and financial structure help to distingu
ish between firms that are more and less liquidity constrained. Ln our view
, liquidity constraints can be given a different interpretation in the case
of transition economies as compared to Western economies. A more in depth
analysis of the data reveals that liquidity constraints, and consequently t
he access to external funds for Bulgarian firm investment, are to be seen a
gainst the background of soft-budget constraints and the failure of the fin
ancial system to enforce an efficient allocation of funds. Ln our view, the
lack of liquidity constraints may actually be seen as a sign of financial
weakness in the case of Bulgaria. JEL classification: D24, P31, P34.
