This paper presents a Kaleckian growth model in which (i) the rate of capacity utilization, the profit share, and the rate of employment are adjusted in the medium run, and (ii) the normal rate of capacity utilization and the expected rate of growth are adjusted in the long run. Both the Kalecki type and the Marglin-Bhaduri type investment functions are introduced. Using the model, we examine w...

Many countries suffer from persistently high unemployment rates. The scope for labour market reforms is often limited to measures that hurt neither shareholders nor workers. This paper develops a policy proposal, which allows the government to reduce wage costs without changing the income positions as determined in the process of wage negotiations. It is shown that the introduction of public pr...

Evolutionary investment strategies have been found to adapt distribution of investors’ fund to technological changes of economic industries. In this paper we use evolutionary algorithm (EA) to improve investment strategies in economic system comparing shares of most profitable investors with other ones. Proposed algorithm selects an optimal combination of investment share in different industrie...

This article describes factors related to the geographic distribution of hemodialysis facilities and the relationship between availability and use. Such facilities tend to be concentrated in the same types of areas as other medical resources, and the number of medical specialists in an area is related to the rate of treatment for renal diseases. The proportion of treatment stations in an area o...

This paper presents an integrated framework for designing profit-maximizing products/services, which can also be produced at reasonable operating difficulty levels. Operating difficulty is represented as a function of product and process attributes, and measures a firm’s relative ease or difficulty in meeting customer demand patterns under specified operating conditions. Earlier optimum product...

AIM OF THE PAPER The paper aims at describing and explaining net profit flows per country for the period 1980-2009. Net profit flows result from Foreign Direct Investment (FDI) stock and profit repatriation: inward stock creating a profit outflow and outward FDI stock a profit inflow. Profit flows, especially 'normal' ones are not commonly researched. THEORETICAL BACKGROUND According to world...

We ask whether increasing HMO penetration causes hospitals to cut back on charity care using California hospital discharge data for 1988-1996. There is little evidence at the hospital level that private hospitals respond to HMOs by turning away uninsured and/or Medicaid patients. In the for-profit sector hospitals actually reduce the share of privately insured patients and increase the shares o...

In this study, we develop a collaborative inventory system consisting of one supplier and one buyer. The objective is to maximize the total profit of the whole system when shortage caused by the imperfect quality can be completely backordered. To ensure mutual benefits to every player, a negotiation mechanism is incorporated to share the profit between both players according to their contributi...

We study the problem of mechanism design for a double auction market where multiple buyers and sellers buy and sell a commodity. We design and implement a matching algorithm that maximizes market liquidity, including the number of transactions and buy/sell-volume. We prove that, given the number of matches, the algorithm also maximizes auctioneer’s profit. Based on the CAT Tournament (Trading A...
