In this paper the role of the capital market is analysed onthe base of a dynamic two-sector model of a closed economy. The way in which the allocation of investment is related to sectoral differences in the rate of profit and to diverging sectoral capital needs as well, turns out to be of great importance for the whole economy. Conclusions are drawn with regard to the long-run equality of profits after an initial disturbance. The role of the capital market is analysed too in connection with the functioning of sectoral labour markets. As far as unemployment and differing sectoral unemployment rates are concerned, the importance of the labour markets is obviously overwhelming. On that base it is possible to make some remarks on macroeconomic and sectoral investment policies with regard to employment.
