Although heterogeneous in the extent, there is economic development, overall, with serious energy and transport-transit relations among countries that is reflected in growing trade turnover year-by-year. However, there are still rather unused resources and capacity in such areas of cooperation among countries as exchange of energy, transport services, agricultural and industrial goods, use of opportunities for tourism, promoting investment and innovation processes and other areas. Certainly, maximum and optimal use of these resources calls for availability of analytical means capable of accounting for relations both within member states and among them. The implementation of computable general equilibrium （CGE） modeling in each member state would thus be of great significance in resolution of these problems both in terms of accounting for input-output linkages within the countries as well as enabling impact of main trading partners and goods and services among countries. The analysis carried out indicates that there are a number of problems in application of CGE model in most of the member states. As such, input-output tables are not compiled in some countries, while in others despite the fact that these tables are compiled, there are no attempts to build the model, yet in other countries, even if the CGE model is implemented, there are difficulties in taking into account the real results in the face of serious problems related to improving national accounts system database. Summarizing these problems, it is possible to conclude that to ensure the application of a CGE model,there is a great need to work out procedures of compilation of a social accounts matrix （SAM） that lies on the basis of this model, for which the relevant statistics of a member state must be improved. Considering the above-mentioned, the presented research, makes procedures and proposals on compilation of SAM, improves statistical data for researching the extent of application of CGE Model in ECO member states, and identifies the degree of availability and organization of relevant data to develop input-output tables and respective SAM.展开更多

John Simmons＇ most comprehensive summary of his mature views on this enduring philosophical problem. In this essay, Simmons critically engages Plato＇s dialogue Crito and culls from it three types of strategies for justifying political obligations： natural duty, associative, and transactional. Simmons argues that natural duty accounts are inherently incapable of providing moral grounding for political obligations, disqualifies both associative and transactional accounts on empirical grounds, and settles for a form of anarchism. I argue, assuming as Simmons does in this essay that natural duties imply obligations of support and obedience to political institutions, that the natural duty strategy promises to provide an escape route out of anarchism.展开更多

The study calculated the value of forest carbon stocks at a total of RMB 817.13 × 10^9 yuan in 2003 and RMB 839.93×10^9 yuan in 2008, with an average annual increase of 0.55 % from an increase in physical carbon sinks. The total value of forest carbon sinks in 2003 and 2008 was RMB 26.73×10^9 yuan and RMB 29.77×10^9 yuan, respectively, with an average annual growth of 2.18 %. From 2003 to 2008, both stock and flow value of forest carbon sinks increased, but the total net flow value of carbon sinks decreased. The growth rate for the environmentally adjusted Gross Domestic Product （eaGDP） for China＇s forest carbon sinks was 17.23 %, outstripping the average growth rate of 9.5 % for the GDP during the same period. The study alsoindicates that China＇s forest carbon sinks affects the GDP in the range of 0.25-0.26 %, and its economic potential is not relatively huge.展开更多

Water is one of the most essential nature resources of human beings; water resources accounting, as an important water resources management tool, is an essential part of compiling the natural resources balance sheet. In this paper, we provide a summary of the historic evolution of water resources accounting and analyze its application in some typical countries. Although water resources accounting and water resources balance sheet reflect different implications and focus, both require water resources accounts as the basis in system establishment.展开更多

Firstly, since creative accounting allows to present a company＇s financial condition in a more favourable light, the ＂advantages＂ of this creativity are identified. This is followed by the enumeration of negative aspects of creative accounting, to illustrate how creativity in accounting may help to falsify the true picture of a company＇s business. Next, the concept of creative accounting and aggressive accounting （the latter, identified rightly, with a financial and accounting fraud） is explained. Finally, methods that are commonly used to falsify accounts, as well as the premises for and the circumstances in which such criminal practices occur, are presented. The paper draws on the results of other scientific works （books and articles published in scientific journals） in which the main and most interesting views of other authors have been presented. A critical analysis method was employed, followed by a comparison of legal texts and legal acts. The scientific conclusion was conducted using the deduction, and, partially, the induction method. It has been shown that it is justified to differentiate in accounting between creativity that is allowable within the established legal limits and practice based upon the use of creativity in a manner contrary to law. Further, it has been concluded that where creativity in accounting goes beyond the limits unambiguously established by the law, it definitely carries attributes of an offence. It has been also noted that due to continuous changes in the functioning conditions of enterprises, the above mentioned limits cannot be fixed or rigid. Thus it is necessary to control and analyse the creativity of accounting and financial staff working in enterprises in order to adapt the binding regulations to the needs of current markets.展开更多

文摘Health care costs are high and continue to rise in most major economies,and the health savings account(HSA)is often viewed as an appealing way to contain health care costs because it can potentially solve the moral hazard spending caused by traditional health insurance.This study uses data from the China Household Finance Survey(CHFS)to empirically examine the effectiveness of HSAs in containing medical expenses and reducing moral hazard.The findings show that HSAs that restrict the use of funds may lead enrollees to discount the value and thus spend more on health care.In addition,the positive effect of HSAs on medical expenses is larger for the relatively healthier group,which may suggest that moral hazard exists regarding the use of HSA funds.The empirical estimates of the HSA effect on medical expenses are robust when a set of covariates are controlled,and HSA balances are instrumented using housing savings account balances.

文摘In Decentralized Machine Learning(DML)systems,system participants contribute their resources to assist others in developing machine learning solutions.Identifying malicious contributions in DML systems is challenging,which has led to the exploration of blockchain technology.Blockchain leverages its transparency and immutability to record the provenance and reliability of training data.However,storing massive datasets or implementing model evaluation processes on smart contracts incurs high computational costs.Additionally,current research on preventing malicious contributions in DML systems primarily focuses on protecting models from being exploited by workers who contribute incorrect or misleading data.However,less attention has been paid to the scenario where malicious requesters intentionally manipulate test data during evaluation to gain an unfair advantage.This paper proposes a transparent and accountable training data sharing method that securely shares data among potentially malicious system participants.First,we introduce a blockchain-based DML system architecture that supports secure training data sharing through the IPFS network.Second,we design a blockchain smart contract to transparently split training datasets into training and test datasets,respectively,without involving system participants.Under the system,transparent and accountable training data sharing can be achieved with attribute-based proxy re-encryption.We demonstrate the security analysis for the system,and conduct experiments on the Ethereum and IPFS platforms to show the feasibility and practicality of the system.
