    • 5 is for secular inflation to develop in the economy. When Gw is less than Gn,C<Cr. There is a shortage of capital goods and labour is plentiful. Profits are high since desired investment is greater than realised investment and the businessmen have a tendency to increase their capital stock. This will lead to secular inflation. In such a situation saving is a virtue for it permits the warranted rate to increase. This instability in Harrod’s model is due to the rigidity of its basic assumptions. They are a fixed production function, a fixed saving ratio, and a fixed growth rate of labour force, Economists have attempted to relieve this rigidity byIt, on. the other hand, G is less than Gw, then C is greater permitting capital and labour substitution in the productionthan Cr. Such a situation leads to secular depression function, by making the saving ratio a function of the profitbecause actual income grows more slowly than what is rate and the growth rate of labour force as a variable in therequired by the productive capacity of the economy leading growth process.to an excess of capital goods (C>Cr). This means thatdesired investment is less than saving and that theaggregate demand falls short of aggregate supply. The resultis fall in output, employment arid income. There would thusbe chronic depression. This is illustrated when from periodt2 onwards G falls below Gw and the two continue to deviatefurther away.Harrod states that once G departs from Gw, it will departfurther and further away from equilibrium. He writes: “Aroundthat line of advance which if adhered to would alone givesatisfaction, centrifugal forces are at work, causing thesystem to depart further and further from the required line of The policy implications of the model are that saving is aadvance.” Thus the equilibrium between G and Gw is a knife- virtue in any inflationary gap economy and vice in aedge equilibrium.

According to Professor technique, saving-income ratio and capital-output ratioKurihara, the Harrod-Domar growth rate of investment fails remain constant during the plan period.to solve the problem of structural unemployment to be foundin underdeveloped countries. It can tackle the problem of‘Keynesian unemployment’ arising out of deficiency ofeffective demand or due to under-utilization of capital. Butwhen population grows faster than accumulation of capitalin an underdeveloped country, structural unemployment willarise due to lack of capital equipment.5.Disguised Unemployment. These models start with thefull employment level of income but such a level is not foundin underdeveloped countries. There exists disguisedunemployment in such countries which cannot be removedby the methods suggested by Harrod-Domar. Thus the mainassumption of the Harrod-Domar models being absent inunderdeveloped Countries, these models are not applicableto them.6.Government Intervention. The Harrod-Domar modelsare based on the assumption that there is no governmentintervention in economic activities. This assumption in notapplicable to underdeveloped countries because they cannotdevelop without government help. In such countries the roleof the state as a ‘pioneer entrepreneur’ in starting largeindustries and in regulating and directing private enterprisehas been increasingly recognised.7. Foreign Trade and Aid. The Harrod-Domar models arebased on ‘ the assumption of a closed economy. Butunderdeveloped countries are open rather than closedeconomies where foreign trade and aid play very crucialroles in their economic development. Both these factorsare the bases of their economic progress.8. Price Changes. These models are based on theunrealistic assumption of a constant price level. But inunderdeveloped countries price changes are inevitable withdevelopment .9.Institutional Changes. Institutional factors have beenassumed to be given in these models. But the reality isthat economic development is not possible withoutinstitutional changes in such countries. Therefore, thesemodels fail to apply in underdeveloped countries.Conclusion. Thus is appears from the above discussionthat the Harrod-Domar models, based as they are onunrealistic assumptions, have little practical application inunderdeveloped countries, Hirschman, therefore, suggeststhat “economics of development, like the underdevelopedcountries themselves, must learn to walk on its own feet,-that is, it must work out its own abstractions.But Professor Kurihara is of the view that though “their policy - IInd Floor, Paliwal Market, Gumanpura KOTA (-0744 -2392059 & 3290500
