Abstract
In this paper an attempt is made to analyse the major detemiinanls of profitability in the
aggregate manufaeturing sector of Tamil Nadu between the pre-liberalization period (1978-80 to
1990-91) and post-liberalization period (1991-92 to 2011-2012). This study was based on ASI
data. The major findings of the study were that excepting lagged labour productivity, the other
variables such as lagged profit level and number of workers were capable to distinguish pre and
post liberalization period profit level. The variable lagged capital productivity having negative
sign implied that this variable acted as a supressed variable. Lagged labour productivity was the
first dominant factor to determine profit level of both the periods.lt is conclude that in order to
improve the profit level of the manufacturing sector of the state of Tamil Nadu in future, it can
rely more on the previous year labour productivity.
