This thesis consist of four self-contained essays.
Essay I estimates the macroeconomic effect of labor market programs on
labor-force participation. The results indicate that labor market programs
have relatively large and positive effects on labor-force participation. If the
number of participants in programs is permanently increased, the labor force
increases by about 70 persons in the long run. The positive effect of labor
market programs is larger in down-turns.
Essay II examine if the flow rate from open unemployment to labor
market programs affect the labor-force participation rate. The results show
that increased probability of moving from open unemployment to labor market
programs have positive effects on the labor-force participation rate. The
positive effects are found for different age groups. The estimated effect is
countercyclical.
Essay III deals with the long-run behavior of Swedish exports and export
prices. I find that i) the cointegration analysis supports the hypothesis of a
”long-run” demand function for Swedish exports; ii) the foreign trend and
the domestic labor trend are equally important for exports in the long-run;
iii) the domestic labor trend is the most important factor behind the changes
in the relative prices; and iv) the productivity trend is important for real
wages.
Essay IV (with Anders Forslund) estimates empirical matching functions
for Sweden, with focus on time aggregation problem, and on stock-flow
matching. The parameter estimates in all estimated models forcefully reject
random matching but are consistent with stock-flow matching. There is evidence
of time aggregation problem in our results, and it provides a warning
against over-confidence in estimates of the scale elasticity of the matching
function derived from annual or quarterly data, if no account is taken to the
within period inflow of job-seekers and vacancies.
