Using aggregate data from the Annual Survey of Industries, we analyze profitability in India’s organized manufacturing sector from 1982-83 to 2012-13. Over the whole period of analysis, the rate of profit grew at about 1 percent per annum, primarily driven by a rising share of profits. We use structural break tests to identify medium and short run regimes. We find two medium run regimes, one of...

The implications of the causal and ubiquitous use, by doctors health-workers and politicians, of the word 'patient' are here discussed. Given that the many implications of this noun do not include health or normality (rather the contrary), it is questionable who, if anyone, profits from its indiscriminate use--and its use, even, at all.

Angola’s difficulties in achieving macro-economic stability and economic liberalization have serious implications for private-sector development. Hyperinflation, and frequent policy reversal, constrain and distort investment in both the informal and formal parts of the private sector. But macro-economic instability arises in part out of mechanisms that subsidize powerful oligopolies, enabling t...

­ We document an experimental study to optimize yield of an ethanol distillation process. The yield is expressed in terms of concentration of the ethanol obtained, and the profit from the process. Concentration is a function of six input factors that can be varied within a given range. Profit is a function of the revenue (which depends on the concentration of ethanol achieved) and costs (which ...

In this paper we follow previous “pseudo-stochastic” approaches that solve stochastic control problems by using deterministic optimal control methods. In a similar manner to the certainty equivalence principle, the suggested model maximizes a given profit function of the expected system outcome. However, unlike the certainty equivalence principle, we model the expected influences of all future ...

Consider a transportation problem with sets of sources and sinks. There are profits and prices on the edges. The goal is to maximize the profit while meeting the following constraints; the total flow going out of a source must not exceed its capacity and the total price of the incoming flow on a sink must not exceed its budget. This problem is closely related to the generalized flow problem. We...

Profit maximization is an important issue to the firms that pursue the largest economic profit possible. In this paper, we consider the profit-maximization problem with the known CobbDouglas production function. Its equivalent geometric programming form is given. Then due to the presence of uncertainties in real world modeling, we have assumed interval uncertainties on the model parameters. The...

It is assumed that in an n-firm single-product oligopoly without product differentiation the firms face an uncertain price function, which is considered random by the firms. At each time period each firm simultaneously maximizes its expected profit and minimizes the variance of the profit since it wants to receive as high as possible profit with the least possible uncertainty. It is assumed tha...

The determination of the target for a manufacturing process involves a complex and fiscally vital decision. This study examines a situation where a product is classified into several grades with respect to specifications of markets. It is reasonably assumed that each grade gives its price and manufacturers cannot produce every item in good grade due to uncontrollable variation of product perfor...
