Several mechanisms are introduced for the procurement of capacity adequacy. In the competitive electricity market, however, it is a GENCO that makes generation investment decision. A GENCO will invest a new generator when it can get more profit than cost. There requires a model to evaluate profit with respect to a new generation investment. In the view of long-term investment, evaluation of a profit of a generator in the electricity market is quite different from that of short-term operation. In this paper, a new profit-evaluation model is proposed for the long-term generation investment. It can treat the probabilistic characteristics of generators, ie, forced-outage-rates, which affect profit of generators.

This study was undertaken to examine the profit efficiency and its determining factors, the investment opportunity, and the challenges of shea butter producers in the northern region of Ghana. The methods employed in this research were the Stochastic Profit Frontier (SPF) model, gain-cost and investment return analyses, as well as Kendall's W statistic using primary data collected from 120 purposively-selected respondents. Results from the analysis indicated that profit efficiency was positively influenced by sex, household size, marital status, educational level, transportation cost, store rent, and price of shea nut with a gain in profit efficiency of 58.5%. The investment analysis demonstrated a net gain per person of $8,077 equivalent to GH₵ 28,270 Ghanaian cedi (GH₵) using 2016 exchange rate (GH₵ 3.5 = $1). Among the challenges identified, the poor quality of shea nuts was the most prioritised challenge with 72.8% agreement among the respondents. Based on these findings, it was recommended that proper training and education, as well as improvement in shea nut quality, should be promoted to improve the profit efficiency of shea butter producers.

The paper examines the impact of information about cash flow from operating activities of firms listed on Vietnam's stock market to the decision making of individual investors. Data were collected from interviews with 160 individual investors about their investment decisions based on information on profit growth and cash flow growth from operating activities. T-test was conducted to research on Vietnam's stock market - a market considered as information that is not really public, transparent and ineffective. The research results show that: (1) investors do not care about cash flow from operating activities when making investment decisions if the company's profits grow positively, (2) information about cash flow from operating activities only affects the decisions of individual investors once profit growth is negative, and (3) conflicting information between profit growth and cash flow growth from business activities significantly affects the confidence and comfort of investors in Vietnam's stock market when they make investment decisions. Then, the study points out the mistake of investors when making investment decisions, and offers recommendations to investors when making investment decisions, not only concerned with profit growth, but also paying special attention to cash flow growth, especially cash flow from the company's business operations.

This research analyzed Raise Capital type and Investment Efficiency for non-profit hospitals in Korea. 152 cases of financial information from 2007 to 2010 were utilized for analysis. As a result of analysis, Raise Capital for Borrowings to total assets was primarily used, taking around 40% on average, and the method of Raise Capital with significant difference among Medical Institutions was Liabilities in Excluded Borrowings to Total Assets and Capital Stock & Capital Reserves to Total Assets. Besides, the relation between Invested capital and Investment efficiency was opposite each other in the non-profit hospitals, and Region was an important element influencing over Productivity per Value Added. In addition, in the investment activity of non-profit hospitals in the light of Investment Efficiency, only hospitals among Medical Institution types had a character of Capital Intensive, and General Hospital and Geriatric & Long-term Medical Care Hospital among Medical Institution types showed a character of Labor Intensive in the light of Performance.

This article suggests a methodology to decide the priority of investment project for venture business under the dynamic circumstance. By the Monte Carlo procedure on the probability distribution of cost and revenue, the model simulates the investment project to estimate profit ratio and risk. The profit ratio is calculated on the yearly basis for the relative comparison. The project risk is calculated as semi-variance under the target yield. After sufficient simulations in this fashion for several projects, the efficient projects with more profit and less risk are selected by the dominance principle. Then the regression equation of the selected projects is produced to find the relative value of the projects. The relative value is obtained through dividing the raw profit ratio by the estimated one on the equation. This value shows the degree to which the simulated project yields over the equation. The priority of investment is decided by this value. An examplary venture business of chemical development for semi-conductor is presented as a case study.

Recognizing the lack of empirical studies on the returns to R & D investment in Korean firms, this paper analyzes the relationships between R & D investment and corporate performances measured by sales growth rate, profit rate and PER. The data used here are from 167 firms in 8 different industries covering the period from 1985 to 1989. The results show that the profit rate is strongly correlated with R & D investment. But unlike the results of most studies previously done in the U.S., R & D investment only weakly and insignificantly correlated with sales growth and PER.

Domestic construction companies are suffering from financing difficulties in the wake of the economic slump in Korea and abroad. During this economic slump, real estate investment trusts (REITs), facilitators for improving financing and stimulating construction businesses, have increasingly expanded since their introduction in 2001. However, in terms of growth speed and marketing size, Korean REITs are falling behind those of other nations. The purpose of this study is to suggest a method for composing a portfolio using the Markowitz portfolio selection model to stimulate REITs. The main contents are as follows. First, a comparative analysis was conducted of increased REIT profit with the application of the Markowitz model and the average REIT profit rate from July 3, 2007, to July 21, 2008, during the investment analysis periods. The results showed that the total profit rate from the Markowitz model was about 10% higher than the average REIT profit rate. Second, the sensitivity was analyzed according to the portfolio's data-gathering and replacement cycle to measure the optimum cycle and yield. The six-mouth profit data collection period showed about 16% higher profits with the Markowitz model than with the REITs. The two-week portfolio change period resulted in about 11% higher profits with the Markowitz model than with the REITs.

Purpose - This study is an effort to assess the role of behavioral biases in investment decision making, specifically for mutual funds, and the moderating role of the investor. Individual investment behavior is concerned with choices about purchasing various securities. However, behavioral finance disputes the concept of perfect rationality and identifies psychological factors and their impact on decision-making. Research design, data, and methodology - A survey questionnaire was designed and used to collect responses using a judgmental sampling technique from 290 investors in the Gwalior Region. Cronbach's Alpha, factor analysis, and linear regression were all used to test the influence of behavioral biases on investment decision. Results - We found that the behavioral biases have a positive impact on investment decisions. Conclusions - This study's results identified three factors influencing investor behavior(rationale, investment skills, and profit making) and four factors influencing investor decisions (profit maker, market analysis, investment plan, seller). The overall results of the study also show that there is no significant relationship between investor behavior and investment decisions by gender in the market.

Industrial management can be achieved in the improvement of productivities and goods qualities, only copy with international competition through technological renovation, This compels the renewal and augment of production equipments, for which more investment has to be projected. Equipment investment, However, has the possibility of assuring the expectation of profit, but the capricious reality of economical situation caused by inflation requires the precedent study of exmining, analyzing and assaying the effect of equipment investment for a long term. The resolution must depend on a technique of what is called engineering economy, which scrutinizes some samples of investment analysis under price fluctuations, which designates through a method of direct calculation that the only less scale of primal investment never bestows wider profit, and recognizes what contribution engineering economy has to the decision making of management.

The rate of conversion to Medical-juridical-persons' ownership of medical institutions has increased rapidly since its start in 1970s in Korea. The most sensitive issue to introduce for-profit medical institutions, ignited particularly by the WTO/DDA negotiations, has sparked considerable debate, stemming largely from conflicting views on the theoretical effects of ownership status on organizational behavior. This study surveyed health-related experts' opinions on allowing for for-profit-firms-owned medical institutions. Some fear that the obligation to maximize the share-holders' return on their investment will cause the medical institutions to eliminate necessary but less lucrative services. They may easily fall under more pressure to generate income, and respond more aggressively than not-for-profit medical institutions to financial pressures. Advocates of for-profit ownership of medical institutions argue that greater responsiveness to the demands of the marketplace will lead to larger investment, higher quality and lower costs to consumers. Referring to both foreign countries' experience and domestic experts' opinions, this study suggests for reform of the current Korean Medical-Juridical-Person(MJP) System. Introduction of so-called “Capital-investment” MJPs is recommended where the properties left in case of their dissolution can be distributed to original investors according to the procedures stipulated in their statutes. However, their annual profits are not allowed to be allocated to investors, but should be reinvested for their medical institutions, as is the case in current MJPs. Their legal aspects are also reviewed in this study.
