The increase of inter-boundary transactions brings a number of benefits for enterprises. However, even when benefits of transfer pricing are evident, multinational organizations still face legal challenges, including performing parts of transactions in another jurisdiction and motives of tax officials in investigating transfer pricing. This is especially true when countries do not want to lose benefits from tax collection. Therefore, many countries and organizations such as the Organization for Economic Cooperation and Development (OECD), Pacific Association of Tax Administrators (PATA), the European Union (EU), and Vietnam have introduced requirements for transfer pricing documentation to prevent transfer pricing manipulation and maintain benefits from taxes. The aim of this research was to assess the compliance of those requirements of foreign direct investment (FDI) enterprises in Vietnam. This article which is a summary of our research includes the following sections: (1) OECD guidelines of transfer pricing documentation; (2) Vietnam regulations of transfer pricing documentation; (3) results of the research; and (4) discussion and conclusion. 展开更多

A goal of transfer pricing may be to maximize after tax revenue by setting transfer prices that reduce the total tax paid. "Transfer pricing" is the pricing of products or services provided by one division to other division of the same corporate entity. Most of the corporate entities are using the method of "Window dressing", which is a technique used in preparation of financial statements of corporate entities. A transnational corporation is any enterprise that undertakes Foreign Direct Investment (FDI), owns or controls income gathering assets in more than one country, produces goods or services outsides its country of origin, or engages in international production. Profitability of the transnational corporate entities is being manipulated by the technique of transfer pricing. Abuse of transfer prices is a key tool used by the corporate entities to think that they have virtually no profit; hence, they shouldn't pay any taxes. India needs to realize the fundamental need for co-operation among tax administrations in order to remove the obstacles that international double taxation presents to the free movement of goods, services and capital between various countries. In this context, one needs to consider that transactions among associated enterprises may take place under different conditions from those taking place among independent enterprises, while enforcing the act of transfer price mechanism. This paper focuses on transfer pricing and its implications in transnational transactions. 展开更多

The Japanese Taxation Agency (JTA) introduced transfer pricing taxation (TPT) in order to suppress the outflow of profits and therefore taxes of Japanese companies, which are expanding overseas. There have been many press reports regarding the application of TPT, and so there is much public attention on this issue. TPT is applied to unnatural transfer prices (TP). If TPT is applied to a multinational company (MNC), the company will need to bear enormous documentation costs in its calculation of the ratable price. In addition, in the last few years, the target of TPT is shifting to the overseas transfer of intangible assets, such as trademarks, royalties, patents, and charges income. As a result, companies have become more careful about TPT and investors tend to pay attention to companies' TPT strategy. With regard to this point, this paper examines how the market evaluates news regarding TP by investigating the market reaction to an initial press report mentioning that a firm was involved in a TP manipulation and may be guilty of tax underpayment. We examine these events both because press reports are currently under intense scrutiny and because there has been very little research on firms that engage in tax sheltering (see, e.g., Graham & Tucker, 2006; Hanlon & Slemrod, 2009). Some view the fact that not all firms engage in tax sheltering as surprising because of the widespread view that shelters, at least in the 1990s, in expectation, offered a positive net present value position. The potential negative public relations effect is often cited as one reason for this "under-sheltering" phenomenon (Bankman, 2004). On the event study analysis, we find that the Japanese capital market has shown a statistically significant negative reaction to the press reports. This result is due to a strong distrust of corporate activity regarding TP strategies. Moreover, in order to clarify the reason why the market responds to reports of TPT being applied, we compute the cumulative abnormal returns (CARs) around the date of the press report and conduct two-stage least-squares estimation to examine where this result regarding the market reaction comes from. Our results indicate that the variables for intangible assets and effective tax rate and the variables which represent the extent of corporate governance (CG) are statistically significant with respect to these reactions. 展开更多

Baoying pumping station is a part of source pumping stations in East Route Project of South-to-North Water Transfer in China. Aiming at the characteristics of head varying, and making use of the function of pump adjustable blade, mathematical models of pumping station optimal operation are established and solved with genetic algorithm. For different total pumping discharge and total pumping volume of water per day, in order to minimize pumping station operation cost, the number and operation duties of running pump units are respectively determined at different periods of time in a day. The results indicate that the saving of electrical cost is significantly effected by the schemes of adjusting blade angles and time-varying electrical price when pumping certain water volume of water per day, and compared with conventional operation schemes (namely, the schemes of pumping station operation at design blade angles based on certain pumping discharge), the electrical cost is saved by 4.73%-31.27%. Also, compared with the electrical cost of conventional operation schemes, the electrical cost is saved by 2.03%-5.79% by the schemes of adjusting blade angles when pumping certain discharge. 展开更多

Agricultural land is the key to large-scale agricultural management,and the transfer price is the key to the success or failure of land transfer. At present,there are many problems in the pricing of rural land transfer in China,such as low price,random pricing,and large price difference,which seriously hinder the development of rural land transfer. Drawing lessons from the research results of domestic and foreign scholars,combined with the actual situation of rural land transfer in China,this paper analyzes the influencing factors of land transfer price in the context of rural land reform. Finally,according to the influence of different factors on the behavior of agricultural land transfer,this paper proposes establishing and perfecting the evaluation system of contracted land,perfecting the evaluation institution of transferred land assets and establishing a unified dynamic monitoring system of land transfer price in the whole country,and then driving the broad masses of farmers to get rich together,which is of great significance to achieving the revitalization of China’s rural areas. 展开更多

Big data knowledge,such as customer demands and consumer preferences,is among the crucial external knowledge that firms need for new product development in the big data environment.Prior research has focused on the profit of big data knowledge providers rather than the profit and pricing schemes of knowledge recipients.This research addresses this theoretical gap and uses theoretical and numerical analysis to compare the profitability of two pricing schemes commonly used by knowledge recipients:subscription pricing and pay-per-use pricing.We find that:(1)the subscription price of big data knowledge has no effect on the optimal time of knowledge transaction in the same pricing scheme,but the usage ratio of the big data knowledge affects the optimal time of knowledge transaction,and the smaller the usage ratio of big data knowledge the earlier the big data knowledge transaction conducts;(2)big data knowledge with a higher update rate can bring greater profits to the firm both in subscription pricing scheme and pay-per-use pricing scheme;(3)a knowledge recipient will choose the knowledge that can bring a higher market share growth rate regardless of what price scheme it adopts,and firms can choose more efficient knowledge in the pay-per-use pricing scheme by adjusting the usage ratio of knowledge usage according to their economic conditions.The model and findings in this paper can help knowledge recipient firms select optimal pricing method and enhance future new product development performance. 展开更多

The factors influencing the water supply price of a hydraulic project include natural conditions and economic policies. This paper thoroughly demonstrates the water price of South-to-North Water Transfer Project from the viewpoint of economic policies. It is considered that if the project is assigned as a profitable one and built depending on commercial loan from bank completely or mostly, the water price will be too high to be undertaken by users,and if the project places the public good at first while considering the economic benefit, its investment mainly relies on the state (national or local governments) appropriation and self-raised funds and a little from the bank loan on favorable terms, the price determined according to the principle of satisfying the cost and reasonable profit will be relatively lower and can be undertaken by the users in the North China where water shortage is serious. The problem of higher water price of agricultural irrigation to the north of the Yellow River can be tackled by taking measures such as "compensating agriculture by industry" according to foreign practical experiences and relevant suggestions. 展开更多

The transfer of the rural collective construction land is increasingly accelerating,and the factors affecting transfer price are manifold. In this paper,the research area is Yichang,and we establish hedonic price model to explore and analyze the factors which affect the collective construction land transfer price. The simulation results show that in geographical factors,the higher degree of prosperity,road accessibility and soundness of infrastructure will result in higher collective construction land transfer price; in economic factors,the higher farmers' per capita net income and added value of the village's tertiary industry will lead to higher collective construction land transfer price; in ownership factors,the integrity of usufruct,disposition and possession has increasingly significant impact on collective construction land transfer price. In the process of establishing rural collective construction land circulation market,the government should gradually improve conditions of collective construction land; strengthen the construction of the rural economy,improve the economic attribute of the collective construction land; establish and improve China's rural collective construction land-related laws and regulations,make the rural collective construction land use rights clear,and give the whole rights of occupation,use,earning and disposition. 展开更多

Cars are regarded as an indispensable means of transportation in Taiwan.Several studies have indicated that the automotive industry has witnessed remarkable advances and that the market of used cars has rapidly expanded.In this study,a price prediction system for used BMW cars was developed.Nine parameters of used cars,including their model,registration year,and transmission style,were analyzed.The data obtained were then divided into three subsets.The first subset was used to compare the results of each algorithm.The predicted values produced by the two algorithms with the most satisfactory results were used as the input of a fully connected neural network.The second subset was used with an optimization algorithm to modify the number of hidden layers in a fully connected neural network and modify the low,medium,and high parameters of the membership function(MF)to achieve model optimization.Finally,the third subset was used for the validation set during the prediction process.These three subsets were divided using k-fold cross-validation to avoid overfitting and selection bias.In conclusion,in this study,a model combining two optimal algorithms(i.e.,random forest and k-nearest neighbors)with several optimization algorithms(i.e.,gray wolf optimizer,multilayer perceptron,and MF)was successfully established.The prediction results obtained indicated a mean square error of 0.0978,a root-mean-square error of 0.3128,a mean absolute error of 0.1903,and a coefficient of determination of 0.9249. 展开更多

As critical piece of China's gradualist economic transition, domestic price reform still faces major challenges. In particular, factor price, which is still tightlycontrolled and not market-based, is lower than market equilibrium price. Factor price distortion not only reduces market efficiency but also affects wealth distribution. Subsequent wealth transfer has, over the past ten to fifieen years, created a powerful vested interests and spawned social resentment, both of which may constitute major hazards in China's future reform and development. Keeping in mind that China will have to address factor price distortion in its next step of reform, this paper takes stock of China's journey toward price rejorm; examines the relationship among factor price distortion, previous economic growth, and policy; and estimates' the size of resulting wealth transfer. 展开更多

At present,further research and exploration on credit risks are being carried out in the global field,and increasingly profound modem credit risks are exposed to the bond market.This requires that we cannot ignore the impact of credit rating migration risk on bond pricing,so as to adapt to the sustainable and healthy development of the bond market under the new normal of China's economy.The innovation point of this paper is to try to analyze the pricing of Convertible bonds in China from the perspective of credit rating migration risk.Tsiveriotis and Femandes(1998)model is selected,and the credit risk in the model is assumed to be caused by the credit rating migration risk,and the credit spread is used to measure the credit rating migration risk.The research conclusion of this paper is as follows:First,it is valid to consider the risk of credit rating migration in the TF(1998)model.The market price of convertible bonds is on average 1.22% higher 1han the theoretical value of the model.In general,the theoretical value obtained from the model has little deviation from the market price,and has a good fitting degree.Second,from the Angle of credit rating,the selection of 32 samples of convertible bonds only empirical research shows that the credit rating of AA-convertible bonds average deviation rate is negative,suggest that the credit rating of AA-the phenomenon of convertible bonds value is underestimated,and AAA credit rating to AA,AA+,the average deviation rate of convertible bonds is positive,that credit rating AA(containing AA)more convertible bond value is overrated phenomenon,and the higher the credit rating of the average deviation rate of convertible bond,the greater the overvalued levels.It has certain guiding significance for participants in the convertible bond market. 展开更多

The synchronicity effect between the financial market and online response for time-series forecasting is an important task with wide applications.This study combines data from the Baidu index(BDI),Google trends(GT),and transfer entropy(TE)to forecast a wide range of futures prices with a focus on China.A forecasting model based on a hybrid gray wolf optimizer(GWO),convolutional neural network(CNN),and long short-term memory(LSTM)is developed.First,Baidu and Google dual-platform search data were selected and constructed as Internetbased consumer price index(ICPI)using principal component analysis.Second,TE is used to quantify the information between online behavior and futures markets.Finally,the effective Internet-based consumer price index(ICPI)and TE are introduced into the GWO-CNN-LSTM model to forecast the daily prices of corn,soybean,polyvinyl chloride(PVC),egg,and rebar futures.The results show that the GWO-CNN-LSTM model has a significant improvement in predicting future prices.Internet-based CPI built on Baidu and Google platforms has a high degree of real-time performance and reduces the platform and language bias of the search data.Our proposed framework can provide predictive decision support for government leaders,market investors,and production activities. 展开更多
