is seen that the gain in the share of 'compensation of employees' was almost entirely due to changes in the share of this factor within each sector in Period I, whereas the gain in Period II was almost entirely due to shift from the unorganised sector to organised sector This finding is consistent with the more pronounced shift observed in favour of tertiary sector in Period II as indicated earlier. It is likely that the expansion of the public sector in general and government services in particular may have contributed to the shift towards the 'compensation of employees'. In the case of shares of 'interest' and 'rent', the findings are in conformity with the analysis emerging from Table 4. The share of 'profits and dividend and mixed income of self- employed declined significantly in both the periods but in Period I, the decline was mainly due to the shift within each of the two sectors whereas the decline in Period II was mainly due to the shift from unorganised sector to organised sector. This phenomenon can further be explained in terms of low profitability of the public sector The above analysis would indicate that the shifts in NDP from the primary sector to the tertiary sector and from the unorganised sector to the organised sector, which were more accentuated in the post-1970-71 period, have caused the shifts in the factor income shares.
