The present paper is a contribution to the building blocks of an investmentmodel within the framework of an integrated macroeconomic model of anIslamic economy. Investment behavior in the model is guided by an Islamicethicalvalue system and profit-sharing financial contracts. The typical firm’sinvestment decision is believed to emerge from a dynamic inter-temporalmaximization exercise within an infinite time horizon. The method of Calculusof Variations is applied to arrive at the optimal investment and employmentcriteria for the firm. The result is then incorporated into a macroeconomicmodel to study the behavior of key endogenous variables like national incomeand the rate of profit-share. Comparative statics exercised within a generalequilibrium framework reveal the potency of monetary policy but the neutralityof fiscal policy with respect to output and employment.IntroductionThe past decade has witnessed a tremendous outpouring of interest aswell as effort in the formalization of economic models based on profit-sharingfinancial arrangements as an Islamic alternative to the conventional interestbasedeconomic system. Several macroeconomic models for interest-freeeconomies have been proposed (Anwar 1987; Habibi 1987; Metwally 1981& 1983). The rigor of an integrated approach to such macroeconomic modelhgdepends on the rigor of the component models, namely, the consumption,investment, monetary, and fiscal relationships. Economists have writtenextensively on different aspects of consumer behavior in Islamic societies.Kahf (1978) and Khan (1984), among others, have contributed to the conceptualand analytical formulation of the consumption function under ...

Rate Of Profit

In a two-sector model with circulating capital, Laibman (1982) shows that a capital-using and labor-saving technical change in the consumption goods sector lowers the rate of profit under the assumption of constant rate of exploitation. This paper generalizes his finding in a two-department multi-sector model that considers the capital advanced. JEL Classification: B51, C67

Negative Growth

In Wealth of Nations, a high rate of profit is associated with sluggish or even negative growth, and vice versa. This is because capital accumulation (and therefore population growth) is driven by parsimony of the masters; and the incentive to self-denial is eroded by a high income too easily obtained. The causal relation between parsimony, the rate of profit, and accumulation is explicated in this article; Adam Smith’s observations concerning “the merchants of Cadiz and Lisbon” examined critically; and some conjectures offered as to why Smith’s successors should have rejected parsimony as a useful concept.
