237' This brief discussion shows chat the conseguences of the internationarmovenenf of workers are far from stra ightforwa rd , varying according to context. rnadditlon, consequences vary according to the type of movenent involved. Thlsdiscussion has focused on the role oi legarry sinctioned labour mrgratron. Theeffects of illegal or undocumented migraiion on labour supply are even [K)recomplex, given that the foreign labour involved is not considered necessary by ihereceiving SCate. A detailed discussion of the implications of undocumentedmlgration for labour supply is beyond the scope of the present study. 3. Labour demand/supply ba lance 238. The dlscussion below briefry considers the implrcations for emproyment in thedeveloping countries hrith market economies of the projections of GDp under thedifferent rong-term scenarios discussed in section rv. Approx r. ma te projections ofemployment as a percentage of the labour force have been made, based on theassunption that productivity rdilr increase 2 per cent per year from r9g0 to 2000.It must be empbasized that these projections ire subject to a high degree ofuncertainty, because of the very rimited avairabiriby of rer-iabre hisioricar dataon employment' productivity and labour force participation rates in the arevelopingcountries- The underlying projections of rabour force partrcipation rates areexpected to be revised, probably upwards, by ILO tn late 1985. 239. For the developlng market economies as a whole (the same countries as thosecovered in the analysis of cDp in section Iv), total employnent was about93 per cent of the labour force in l9g0 and has farren sharply to onr.y g3 per centin 1985' given tbe very sro, growth of cDp since 1980 (see table 35). whir.e thisimplies an unemployment rate of 17 per cent, that figure should probably belnterpreted as including some shifting of labour from the formal sector to theinformal sector, rather than consi.sting entirely of open unemployment. Forcomparison, the limited available estimates of open unemployment in urban areas of12 r'atin American countries averaged around g to r0 per cent in lgg2-g3, as shovrni.n table 32 above.A/ 40 /5L9 Engl-i sh Page 107 Table 35.

**Analysis**
The text discusses the consequences of international migration of workers, labor supply and demand, employment rates, and GDP growth in developing countries with market economies. It also mentions the limitations of data availability and the uncertainty of projections. These topics suggest that the text is primarily focused on economic development and employment.
