摘要:

ABSTRACTAn optimizing model of a dual economy involving five sectors (subsistence or traditional agriculture, commercial agriculture, manufacturing goods, capital goods, and government) is used to investigate three questions. Firstly, under what conditions should LDC's emphasize the development of traditional agriculture rather than commercial agriculture. Secondly, what type of considerations are relevant in the allocation of capital goods among agricultural mechanization, manufacturing, and reinvestment in the capital goods industry. Finally, the interrelationships between industry and agriculture have been explored. This study differs from earlier dual economy studies since the agricultural sectors require manufactured inputs and capital goods from the non‐agricultural sector

摘要:

ABSTRACTDue to imperfect information, consumer behaviour often deviates in a systematic quantifiable way from informed optimising behaviour. This paper seeks to take account of this in deriving optimal price and allocation rules. Using a partial equilibrium approach, Part I argues that it may be possible to reconstruct consumers ‘informed’ behaviour from their observed behaviour, and to derive from this their optimal demand levels. Optimal prices, that is the prices which will induce consumers to purchase the optimal quantities, can then be derived. This pricing strategy is illustrated by the analysis of example in Parts II and

摘要:

ABSTRACTBy postulating convex‐to‐origin Phillips curves and a concave‐to‐origin indifference map in the unemployment‐inflation space, we find that, the pure gains from trade aside, the post‐trade equilibrium under flexible exchange rates cannot be superior to that under autarky because a variable exchange rate generates no countercyclical forces. Under a fixed exchange rate regime, a country can be better off (worse off) after trade than before trade if the foreign rate of inflation is lower (higher) than that prevailing in autarkic equilibrium. If countries co‐operate and jointly reduce their rates of inflation, they can improve their welfare and yet maintain balance of payments equilibrium. If the rate of profit is a variable determining the position of the Phillips relationship, international trade improves the welfare of the labour‐abundant and worsens that of the capital

摘要:

ABSTRACTIn this paper, optimal policies for a national economic system modelled and modified on the basis of the cyclical growth theory developed by Keynes – Phillips – Bergstrom (4) are investigated with the aid of Pontryagin Maximum Principle. Further, a numerical example is presented using the computer programme given in the reference (15, pp. 20–31) with some modification. Its details are discussed in Sect

摘要:

ABSTRACTThe paper presents a set of conditions for exact aggregation of linear models based on duality. Such conditions admit rather general structures and allow for parametric variation of the coefficient vectors in the objective function and constraints. They do require that the activities to be aggregated be characterized by a proportionality relation. The issue of « natural » versus unrestricted weights is discussed at some lenght and the advantage of using unrestricted operators is clearly pointed ou
