So the foundation plans to contribute a total of US 50 million for a suitable team of schools per year under the condition of avoiding repeated other large grant organizations’ investment. The DEA (Data Estimate Analysis) model is developed to determine an optimal investment strategy for the Goodgrant Foundation. In this paper, two questions were solved: how to choose a suitable team of schools and how to allocate the investment. Before the establishment of the model, the EXCEL software is used to preprocess data. Then the DEA model which includes two models in the paper is developed. For the first question, the CCR model is established to rank schools which used efficiency from DEAP 2.1. For the second question, the resource allocation model is established to allocate investment amount by weights of allocation from MATLAB software. Accordingly, the optimal investment strategy is received for the Goodgrant Foundation. Through the analysis above, 23 from 293 schools are selected to invest. Then the schools are ranked and the investment of US 50 million for 23 schools is allocated.展开更多

When the cooperative development coefficient is large, it is more rational for the firm to cooperate with the MSSP to develop the information system. When the cooperative development coefficient is small, it is more rational for the firm to develop the information system by its own efforts. It also shows that the attacker's maximum expected utility increases with the increase in the attacker 's breach probability and cost coefficient when the cooperative development coefficient is small. On the contrary, it decreases when the cooperative development coefficient is large.展开更多

The study investigated the investment strategy of the Temasek Holdings as one of the most successful SWFs which is owned by the government of Singapore. Temasek Holdings was founded in 1974 to manage part of the government's revenues. Present turbulent times create a big pressure on healthy investment strategy of the SWFs. But total shareholder return for Temasek since its inception in 1974 has been a healthy 17% compounded annually. The main objective of the paper is to focus on the role of the Temasek Holdings as a company managed on commercial principles with an aim to achieve long-term sustainable returns. The study also analyzed Temasek Holdings'investment strategy. The study provides answers to questions like: why Temasek is of the most successful SWFs and what is the fund risk management? Another part of the paper compares investment strategy of the Temasek Holdings with other SWFs. The study has been conducted mainly on the basis of literature survey, secondary information and with using various web sites and research paper. The analysis has been also based on disclosures appearing in the Temasek annual reports over the period from 2008 to 2010.展开更多

The database includesrelevant qualitative factors, such as foundational characteristics, the technologicalprofile of the startup, and its funding structure. Using the full population of FinTechstartups operating in Spain from 2005 to 2017, we observe that most of these firms areunprofitable within three years of their inception. Combining panel data and survivalanalyses, we empirically find that large and solvent FinTech firms founded by singleentrepreneurs in an incubator or accelerator program are more likely to be profitableand prevail. FinTech firms reach their break-even points faster if they receive fundingthrough seed capital.展开更多

This paper analyzes the franchise value change information of state-owned commercial bank. The franchise value change information shows that the franchise value of state-owned Commercial Bank is descending. Along with the descending of the franchise value, state-owned commercial bank strengthens its high risk investment motive when it chooses its investment strategy. State-owned commercial bank tends to run the high risk of investing securities because its investment variety is very sparse. Based on the theoretical principle of how to control securities investment risk, this paper proposes some countermeasures and suggestions that state-owned commercial bank strengthen the control of its securities investment risk in order to perfect its investment strategy.展开更多

The results show that the establishment or upgrade of partnerships has had a positive effect on Chinese firms' decisions on OFDI for at least the short term, especially for firms with higher demand for policy guarantees from the government, such as noncentral firms and non-Beijing firms. The results also show that the increase in OFDI is concentrated in host countries with higher political risks, such as developing countries, neighboring countries, and Belt and Road countries,which is consistent with China's diplomatic focus.Our research proves that China's diplomatic strategy can assist firms to invest abroad.展开更多

The surplus process is described by a classical Cramér-Lunderg model and the financial market contains a market index, a risk-free asset and a pair of mispriced stocks, where the expected return rate of the stocks and the mispricing follow mean reverting processes which take into account liquidity constraints. In particular, both the insurance and reinsurance premium are assumed to be calculated via the variance premium principle. By employing the dynamic programming approach, we derive the explicit optimal robust reinsurance-investment strategy and the optimal value function.展开更多

There- fore, circular economy requires a lot of financial support. Facing investment and financing problems of circular economy by enterprise, the govern- ment should strengthen the regulatory role, increase investment support on circular economy, strengthen the bank's green credit business, reduce barriers to business loans, diversify financing channels for enterprises, guide social investment's flow direction, and promote circular economy form- ing larger scale, thereby providing policy support for building a resource-saving and environment-friendly society.展开更多

Research indicates that low matching extent amongst the above three decision-makers is an important reason for the disadvantage of the western region in terms of FDI attraction,and this situation will not change in the short term. In addition,this article also sheds light on how to increase matching extent.展开更多

文摘In order to solve the problem of howa firm makes an optimal choice in developing information systems when faced with the following three modes: development by its own efforts, outsourcing them to a managed security service provider( MSSP) and cooperating with the MSSP, the firm 's optimal investment strategies are discussed by modeling and analyzing the maximum expected utility in the above cases under the condition that the firm plays games with an attacker.The results showthat the best choice for a firm is determined by the reasonable range of the cooperative development coefficient and applicable conditions. When the cooperative development coefficient is large, it is more rational for the firm to cooperate with the MSSP to develop the information system. When the cooperative development coefficient is small, it is more rational for the firm to develop the information system by its own efforts. It also shows that the attacker's maximum expected utility increases with the increase in the attacker 's breach probability and cost coefficient when the cooperative development coefficient is small.

文摘This paper considers a robust optimal reinsurance-investment problem for an insurer with mispricing and model ambiguity. The surplus process is described by a classical Cramér-Lunderg model and the financial market contains a market index, a risk-free asset and a pair of mispriced stocks, where the expected return rate of the stocks and the mispricing follow mean reverting processes which take into account liquidity constraints. In particular, both the insurance and reinsurance premium are assumed to be calculated via the variance premium principle. By employing the dynamic programming approach, we derive the explicit optimal robust reinsurance-investment strategy and the optimal value function.
