EFFICIENCY, PLANNING AND REFORMS IN SOCIALIST ECONOMIES 45 6. See in this context Ashok Mitra, Terms of Trade and Class Relations London/ 1977, ch.l. 7. Joan Robinson in her 'Philosophy of Prices,' published in Collected Economic Papers Volume 2, drew a distinction between two different kinds of prices. In one situation there is mobility of capital and labour across sectors and the price of the sector's product is such as to ensure for workers the average wage and for capital the average rate of profit which prevails elsewhere; in the other situation, characterising in her view the agricultural sector in particular, the sector is insulated and its price is not linked to any such average. In conditions of monopoly, especially the type of monopoly that would emerge under socialist commodity production, each sector according to my argument would behave as if it were ah insulated sector. 8. See R.E. Rowfchorn 'Conflict, Inflation and ^loney^ Cambridge Journal of Economics, 1977. 9. I have argued in my paper Terms of Trade and the Rate of Inflation' (mimeo.) that the primary-producing sector often provides in capitalist conditions, and has provided in India in recent years, such a cushion against an acceleration of inflation. 10. And if this counteracting tendency, though existent is not strong enough, the economy may end up with both widening inequalities as well as an acceleration of inflation at a rate mor^ gentle than would have been the case otherwise. 11.

Reference may be made to Maurice Dobb's Welfare Economics and the Economics of Socialism (London 1969) for a review of the issues. 13.

It is noteworthy that the most successful capitalist country of today, namely Japan, has eschewed the use of the usual capitalist method of enforcing work-discipline, and some even attribute its success to this very fact. See M.Morishima, Why Has Japan Succeeded? London 1982. It is ironic that socialist economists are seeing the virtues of market coercion as a means of enforcing work-discipline when successful capitalism has transcended it.
