Tables 52 and 53 below assemble.historical estirnates relatinq to the investment effort, investment efficiency and saving rates of different groups of rror ld economieg for the periods covered by the Development Decades. From thesetables it can be seen that changes in resource allocation in most groups of developing countries have moved in directions supportive of faster growth duringthe first and Second Development Decades, with both investment and saving shares generally rising. Over the decades of the 1950s and 1970s, for example, the share of capital formation in cDp in all groups of developingcountriesr with tbe exception of the least developed economies, rose to thatprevailing in the economicaLly advanced economies. whiLe the rise in investmenteffort over that period may be less pronounced in the least developed countries, it none the less represenbed a dramatic and apparently a sustained increase. Althoughno explicit targets for investnent effort are mentioned in the proqrammes for thefirst and Second Development Decades, the rise in investment shares recotded duringthis period in the developing countries would appear !o be conslstent with theiroverall aspirations in this area.A/ 40 /5r9 Eng li sh Page 139 Table 52.

**Analysis**
The text appears to be discussing the investment effort, investment efficiency, and saving rates of different groups of developing countries over several decades. It mentions the Development Decades and the rise of investment shares in developing countries, as well as the incremental capital-output ratio. This suggests that the text is focused on economic development and the mobilization of resources.
