We study compatibility decisions of competing platforms when they generate profits through both hardware sales and royalties from content sales. We show that when the two platforms provide different values to their users, their major sources of profits may differ—one platform may generate most of its profits from hardware sales, while the other’s profits will result mostly from royalties of con...

For one parametric smooth family of pairs of control systems and profit densities on the circle, the transition between optimal strategies of cyclic and stationary types in the problem of maximization of infinite horizon averaged profit is studied. We show that only two types of such transition can be observed for a generic pair, study the corresponding singularities of the averaged profit as a...

In this paper we develop an economic order quantity model to investigate the optimal replenishment policies for instantaneous deteriorating items under inflation and trade credit. Demand rate is a linear function of selling price and decreases negative exponentially with time over a finite planning horizon. Shortages are allowed and partially backlogged. Under these conditions, we model the ret...

This paper addresses the problem of allocating resources in a divisionalized firm. The firm consists of II distinct divisions. Inputs have to be allocated across the divisions and the profit function of each division may in general depend on the whole allocation of inputs. The manager of the firm does not know the divisional profit functions and yet would like to allocate resources in a profit-...

We demonstrate a negative relationship between pro-market reforms and the sustainability of superior profits in an emerging economy. The decline in sustainability of superior profits shows that pro-market reforms bring significant threats in addition to the various opportunities such as greater availability of production factors and greater freedom to enter and operate businesses highlighted in...

This paper investigates the effect of capacity constraints on the sustainability of collusion in markets subject to cyclical demand fluctuations. In the absence of capacity constraints (i.e. a limiting case of our model), Haltiwanger and Harrington (1991) show that firms find it more difficult to collude during periods of decreasing demand. We find that this prediction can be overturned if firm...

The study is an analysis of processing methods, marketing channels, and profitability determinants of selected cassava products in Kogi state, Nigeria. The study was carried out in Kogi East senatorial District of the state. A multi-stage sampling technique was employed in the selection of 120 respondents from whom information were collected and analyzed. The data used for the study were collec...

The objectives of this study were 1) to propose a profit function for Italian Chianina beef cattle; 2) to derive economic values for some biological variables in beef cows, specifically, production expressed as the number of calves born alive per year (NACY), age at the insemination that resulted in the birth of the first calf (FI), and length of productive life (LPL); and 3) to investigate the...

Although a comprehensive framework for most of the theoretical foundations of duality has been available to economists since the seminal work by Shephard in 1953, empirical applications of duality have become popular mainly during the last ten years. The first empirical study which I am aware of that exploited duality theory is the one by Nerlove in 1963 which estimated a CobbDouglas cost funct...
