It analyzes the common real options and real options-based strategic investments and aligns them with the common types of public-private partnership （PPP） infrastructure projects. It then develops models to show that the real options incorporated into the different types of PPP infrastructure projects affect the level of direct government cash supports to the projects and hence the viabilities of such projects. The paper however shows that the relationship between the embedded real options and viabilities of infrastructure projects can be influenced by such factors as contract period and percentage of private sector contributions to the projects.展开更多

These investments are crucial for the long-term existence and development of a company, but their value is not disclosed on the assets side of the classical balance sheet. The most important argument of the mentioned approach＇s promoters is that the economic benefits stemming from such investments are uncertain. However, investments in human capital are those with the highest long-term benefits for the company. Therefore, human capital is the only element of the business process that can add value. Other elements （equipment, materials, and services） just transfer their value to products and services. In this paper, the elements of investments in human capital and the methods used to evaluate these investments are addressed. In addition, uniquely shaped financial performance ratios related to investments in human capital are presented along with the system of integrated ratios.展开更多

However, the roles of FDIs are very different between regions, partly due to the different locational preference of various source countries. Some facts show that FDIs from Hongkong - Macao indicate a strong locational preference. Therefore, this paper attempts to make an empirical research on the locational preference of Hongkong - Macao’s FDIs and their spatial diffusion under the support of statistical data with regrereion analysis. In this paper, three statistical models, including the special location model, the general location model and the spatial diffusion model, are created. The results show that this kind of analysis is successful. The major conclusions are as follows. (1) The optimum location for FDIs from Hongkong - Macao lies in the coastal area, especially Guangdong, Hainan, Jiangsu, Shandong, Fujian provinces. Besides, Hubei Province is also an important radon. (2) The FDIs from HongkongMacao in China have diffused gradually from the coastal provinces to the inland regions, the northem and the metropolis and from the locations that had attracted a large number of investments to their vicinities since the 1990s. (3) The special location factors, such as the herder effect, the unique social and kinship ties are the key factors determining the special locational distribution. (4) The general location and spatial diffusion of Hongkong - Macao’s FDIs are the results of interplay of several economic factors. They are the economic scale and advantage, the growth rate, the laier force and economic extrovert etc.展开更多

However, the rapid setting rate of investment slurry has up to now been a barrier to extend the use of such slurry in preparation of medium-sized ceramic moulds. This paper proposes a new process of rapid fabrication of magnesia-phosphate-bonded investment ceramic moulds for medium-sized superalloy castings utilizing bauxite and mullite as refractory aggregates. In order to determine the properties of magnesia-phosphate-bonded bauxite-mullite investments (MPBBMI), a series of experiments were conducted, including modifciation of the workable time of slurry by liquid(mL)/powder(g)(L/P) ratio and addition of boric acid as retard agent and sodium tri-polyphosphate (STP) as strengthening agent, and adjustment of bauxite (g)/mullite(g)(B/M) ratio for mechanical strength. Mechanical vibration was applied to improve initial setting time and fluidity when pouring investment slurry; then an intermediate size ceramic mould for superalloy castings was manufactured by means of this rapid preparing process with MPBBMI material. The results showed that the MPBBMI slurry exhibits proper initial setting time and excellent fluidity when the L/P ratio is 0.64 and the boric acid content is 0.88wt.%. The fired specimens made from the MPBBMI material demonstrated adequate compression strength to withstand impact force of molten metal when the B/M ratio is 0.89 and the STP content is 0.92wt.%. The experimental results confirmed the feasibility of the proposed rapid fabricating process for medium-sized ceramic moulds with MPBBMI material by appropriate measures.展开更多

Under the conditions of an evident shortage of liquid assets, the financial capital has moved from real to the financial sector, which led companies to over-indebtedness and shutdown of their own capacities. Therefore, capital investments largely depend on internal financing sources and the ability of companies to internally generate funds for investments. In this regard, an emphasis is placed on the difference in the assessment of the company＇s investment capacity based on internal financing sources, which are measured using static and dynamic indicators in order to prove the necessity of applying dynamic coefficients, which are unfortunately not present in our domestic practice. The paper examines and proves the advantages of the use of the dynamic approach for such analyses using the example of energy sector, which is one of the most important branches in Serbian economy.展开更多

Foreign economic and political sanctions have a growing negative impact. It is very important for the agriculture industry to be supported by the Russian state budget and to have administrative support, the institutional structure of the state, quantitative and qualitative indicators of national support： federal, regional, and municipal.

In today＇s economic conditions, it is necessary to observe all the influencing factors and examine their impact on the investments in the economy of some country. The goal of each country is to create a favorable climate （conditions） for the investments, because they stimulate the growth and development of the country. The aim of this paper is to point of the current situation （the past few years） of the foreign investments in Serbia＇s economy and to highlight the main factors that influenced this situation. In a past few years, there is another trend of unexploited resource of investment seen in Serbia, which is more and more attractive in the region, but unfortunately unjustly neglected in Serbia. These sources are venture capital and private equity funds. Some of the influencing factors that must be emphasized are the country＇s general economic situation, political risks, taxation, the financing of the investments, the government＇s incentives （subsidies）, support from some specialized institutions, etc..展开更多

The incandescent bulbs, compact fluorescent lamp bulbs as well as fluorescent tubes are mostly used to convert electrical energy into light. The said light sources have many disadvantages such as excessive power consumption leading to giant bills of electricity, short life span leading to continuous replacement of lamps, and emission of CO2. Application of light-emitting diode (LED) lamps in lighting in long term suppresses the aforementioned problems resulting into saving of money that will be used for running new small investments.展开更多

文摘This paper provides evidence for the relationship between various forms of real options in infrastructure projects and the types and levels of government supports to the infrastructure investments. It analyzes the common real options and real options-based strategic investments and aligns them with the common types of public-private partnership （PPP） infrastructure projects. It then develops models to show that the real options incorporated into the different types of PPP infrastructure projects affect the level of direct government cash supports to the projects and hence the viabilities of such projects. The paper however shows that the relationship between the embedded real options and viabilities of infrastructure projects can be influenced by such factors as contract period and percentage of private sector contributions to the projects.
