The present authors have put forward a projective geometry model of rational trading. The expected (mean) value of the time that is necessary to strike a deal and the profit strongly depend on the adopted strategies. A frequent trader often prefers maximal profit intensity to the maximization of profit resulting from a separate transaction because the gross profit/income is the adopted/recommen...

The South African sugar industry remains under pressure to increase sugarcane supply to mills, many of which operate below optimal capacity. One opportunity for the industry, that of significant spatial expansion, lies in small grower, communally-owned areas where much of the land is suited to sugarcane production. Extensive investment capital has been channeled into small grower projects with ...

This paper evaluates the impact that investigation and regulation of the UK petrol industry has had on the profitability of the companies. Using a gross margin for petrol, we estimate a series of variable parameter autoregressive processes. The results demonstrate that the 1979 Monopolies and Mergers Commission investigation into the industry, caused a long-term decline in profit margins in the...

The paper aims to investigate the effects of Inventory Turnover and Inventory Days on firm performance in the United Kingdom agricultural machinery industry by examining past literature reviews and empirical evidence of a primary research. Specific performance measures such as Earnings before Interest and Tax to Sales Ratio, Gross Profit to Sales Ratio, and Return on Assets are examined by cond...

Although an increasing number of hospitals are reporting net losses from the Medicare prospective payment system (PPS) for inpatient care, overall hospital facility profit rates remain stable. Hospitals that reported net profits in the Medicare inpatient PPS sector in PPS 7 (1990) had smaller increases in Medicare expenses than hospitals that reported PPS losses in PPS 7. Medicare PPS inpatient...

Our objective was to evaluate life-cycle performance of flocks of two Egyptian breeds, Rahmani (R) and Ossimi (O), and their crosses with Finnish Landrace (F) in two management systems. Management systems were one mating season per year (1M) and three mating seasons per 2 yr (3M). Breeds and crosses studied included purebred R and O, F1 crosses 1/2F-1/2R (FR) and 1/2F-1/2O (FO), and inter se ma...

The multi-party (multi-agent) scheduling problems have received increasing attention for about ten years. Most of the research only focuses on the scheduling aspect while a distinct cooperative game model is originally constructed for a two-party setting in this literature. This game model is established to highlight the reasonable (cooperative) profit sharing, although the current multi-agent ...

Genetic improvement programs in dairy cattle have until recently focused on increasing net profit by increasing gross income per cow, rather than reducing costs of production [1]. Strong selection pressure on yield traits coupled with management practices aimed at maximizing production may have resulted in undesirable side effects related to decreased fitness [2]. These concerns have been confi...
