Maximizing the profit and minimizing the loss notwithstanding the trend of the market is always desirable in any investment strategy. The present research develops an investment strategy, which has been verified effective in the real world, by employing self-organizing map neural network for mutual funds tracking the trends of stock market indices according to macroeconomics indicators and weig...

In this paper, we formulate a firm’s investment in a production facility with maximum capacity and outsourcing strategy. Existing literature of capacity choice results in an explosive capacity and long delay in investment. Actually, there are slight possibility that a firm installs a facility with an explosive capacity, instead, a firm can outsource production when the demand exceeds its capaci...

We analyze an economy where firms undertake both innovation and adoption of technologies from the world technology frontier. The selection of high-skill managers and firms is more important for innovation than for adoption. As the economy approaches the frontier, selection becomes more important. Countries at early stages of development pursue an investment-based strategy, which relies on exist...

The Intelligent Model for Stock Investment with Buffett Strategy, Classifier System, Neural Network and Linear Programming” was studied for developing an intelligent model which can learn more knowledge regarding to stock investment with artificial intelligence technology. Classifier system, neural network, fundamental financial investment factors and linear programming are the fundamental comp...

In portfolio optimization problems, the minimum expected investment risk is not always smaller than the expected minimal investment risk. That is, using a well-known approach from operations research, it is possible to derive a strategy that minimizes the expected investment risk, but this strategy does not always result in the best rate of return on assets. Prior to making investment decisions...

The study of memory for event duration in pigeons has, for the most part, centered on an unusual behavioral phenomenon and an interesting theoretical explanation for it. A typical experiment on memory for event duration involves trials initiated by a sample stimulus that is either short or long in duration (e.g., 2 vs. 10 sec of houselight) and that is later followed by the simultaneous present...

We analyze the optimal investment strategy of a firm that can complete a project either in one stage at a single freely chosen time point or in incremental steps at distinct time points. The presence of economies of scale gives rise to the following trade-off: lumpy investment has a lower total cost, but stepwise investment gives more flexibility by letting the firm choose the timing individual...

This paper utilizes survey data on labor union coverage at the firm level to examine union-nonunion differences in investment activity among 706 U.S. companies during the 1970s. Consistent with a model of union rent seeking, firm-level collective bargaining is associated with significantly lower physical capital and R&D investment, even following extensive control for firm and industry characte...
