Abstract | ||
The paper investigates the changes in job creation and destruction flows considering a very
disaggregate level of analysis. If institutional setup plays a more important role compared to other
factors, than at lower levels of aggregation we should observe that job flows regularities are in line
with national ones. We explore the issue using a unique database on the population of firms in
Trentino (a North-Eastern Province of Italy) from 1991 to 2001. We find that: (a) job flows show
a ”fractal” nature, i.e. many regularities appear to be scale invariant (magnitude of flows and their
persistence). In particular job flows magnitude is in line with the average values for Italy; (b) there
are some qualifications to ”fractality”: entrant firms’ contribution to job creation process is lower
than the corresponding contribution at national level, whereas the job destruction share accounted
for by exit firms is around 30%, in line with stylized facts; (c) size and age shape the job flows; (d)
shifts of jobs between macro sectors are rare.
