This paper is aim to test how market orientation is related to the investment decision making. After controlling for firm-specific factors, this study finds a significantly positive relationship between market orientation and R&D expenditures, especially firms with high ratio of intangible assets and low ratio of abnormal inventory assets. Under conditions of low quality of earnings, the negative relation between market orientation and R&D expenditures is enhanced in electronic related industries. This indicates that the relation between market orientation and R&D expenditures may exhibit more reasonable patterns for investment decision of firms in technology driven business environment.

Real options provide a new and productive way to view corporate r&d investment decisions. DCF approach is well established and beloved of financial executives, but is known to systematically underestimate investment value under significant uncertainty. Though real options are not inherent in a r&d investment, they can be used to compute the investment value including managerial flexibility like option value. In this paper, we explain how the interval of option value in black-scholes model can be estimated using simulation. We also present a process framework for interval estimation of volatility and efficient of period of investment value. In such a setting, we can obtain the appropriate interval estimation of the expanded investment value.

We investigate an optimal retirement time and consumption/investment policy of a wage earner who expects to find a better investment opportunity after retirement by being freed from other work and participating fully in the financial market. We obtain a closed form solution to the optimization problem by using a dynamic programming method under general time-separable von Neumann-Morgenstern utility. It is optimal for the wage earner to retire from work if and only if his wealth exceeds a certain critical level which is obtained from a free boundary value problem. The wage earner consumes less and takes more risk than he would without anticipation of a better investment opportunity.

The use of on-premises technology in the business environment to create a competitive advantage is ushering in a new era known as digital transformation. As the foundation of digital transformation of enterprises, information technology still has a paradoxical effect on enterprises. This paper documents the effect of investments in IT on a firm's long-term profitability performance measures as return on assets (ROA), as well as tests whether the earlier entrant and the later entrant are different in IT investment performance. Using a sample of China's public firms IT investment data between 2016 and 2019, the result indicates that IT investment in firms have a positive effect on firm performance in full sample, but not in the financial industry firms. When it comes to the different investment time, the result shows no significant difference between the earlier entrant firm and the later entrant firm in the full sample, but not in the case of software industry sample. This should help alleviate the concerns that some have expressed about the viability of digital transformation given the highly publicized IT investment and implementation problems at some firms.

This paper considers a supply chain consisting of a manufacturer under the cap-and-trade emissions regulation and a permit supplier. We study joint production quantity and investment in reducing permit production cost decisions for centralized and decentralized supply chains. We formulate two supply chain contracts with aims to coordinate the decentralized supply chain; wholesale price contract and cost-sharing contract. Under the cost-sharing contract, the manufacturer shares a part of the investment in reducing permit production cost and then is allowed to purchase emission permit at a lower price. We analytically find that the proposed cost-sharing contract with reasonable parameters can coordinate the supply chain whereas the wholesale price contract is not desirable to achieve the system-wide profit. Numerical example is followed to support the analysis.

This paper develops an analytic model for minimizing the cost of distributing items by truck from one supplier to many customers under Milk run logistics strategy. The model derives formulas for not only inventory and transportation costs but also costs associated with carbon emission trading scheme. In addition, monetary investment for reducing carbon emissions is considered. We analyze how to determine optimal shipment size and carbon emission reduction investment. The purpose of this work is to evaluate the effects of carbon emission trading scheme on the Milk run logistics strategy in terms of how much to reduce carbon emissions and/or inventory and transportation costs. We analytically show that it is possible to reduce carbon emissions while reducing inventory and transportation costs by introducing cap-and-trade carbon emission trading scheme under certain conditions.

It is difficult to justify an IT investment unless the investment is expected to have a direct impact on a corporation's performance under rapidly changing business environment. It is important to demonstrate the benefit of the investment through a pre-investment assessment process to induce the executive's decision. This paper presents a methodology to assess the investment by analyzing cost and benefit of the investment. This methodology shows tangible cost as well as hidden cost by analyzing total cost of ownership. The methodology also produces ROI by performing cost benefit analysis including financial and non-financial factors. This paper suggests a systematic way to support If investment decision marking process by evaluating the investment objectively.

The scope of umbrella clause is very important because it is possible to extend or reduce the range of protection of the investment. Umbrella clause stipulated in the majority of BIT is often controversial, since there is no established criteria for the scope. So, this study considered ICSID arbitration cases related to the scope of umbrella clause. There are two different approaches for the scope of umbrella clause by arbitral tribunals. First, all of the disputes on the investment contract elevated to the disputes on the BIT. And umbrella clause can be applied that the host state entered into investment contract not only as a sovereign but also as a merchant. Second, all of the claims on the investment contract don't elevate to the claims on the BIT. Umbrella clause can be applied only if the host state violates the protected investment contractual rights and obligation under the BIT. And umbrella clause can be applied that the host state entered into investment contract as a sovereign but not as a merchant. Therefore, this study suggests to concretely specify the scope of umbrella clause under the BIT. And it is necessary to improve predictability by establishing continual database of the scope of umbrella clause and to prepare for investment disputes related to the scope of umbrella clause.

This study compared household's investment behaviors over consumer's ages before and after the economic crisis using 1995 and 2000 National Survey of Family Income and Expenditure in korea. Household's investment behaviors were compared in terms of household's financial statements, amounts and proportions invested in various assets, and rate of return on investments. The proportion invested in securities of all households. In terms of the proportion invested, consumers under 40s increased the proportion invested in insurance while consumers over 50s increased the proportion invested in savings and trusts in 1995 than in 2000. Consumers of all ages increased the proportion invested in securities in 2000 than in 1995. Young households had higher rate of return in 1995 while old households had higher rate of return in 2000.

These days, the interest in the gas safety management has been increasing in our society, It needs the estimates to later investment in points of the gas safety management investment for prevention costs from gas accidents. It is written the general concept of gas safety management and the items that should be invested under the current policy. However they are not defined clearly and We have lots of difficulties in adapting them to actual spots and understanding them by their carry-out. When it follows the current safety standards, they doesn't meet the possibilities of mutual comparison, because gas safety management investment's definition is different. And sufficient information is not supported to efficiency adjudication of gas safety management investment. In this paper, you can find that Gas safety management is defined in order to more effective gas safety management investment, and the Socioscentific approach method was used to decide the gas safety management items that shall be invested.
