There are 9.56 million accountants in China, who are working in different size firms and nonprofit organizations. The objective of this article is to examine the quantitative relationship between the firm size and the quantity of accountants working for the firm. In this paper, the employees, sales revenues, and total assets in a firm are employed to measure firm size. The authors collect and analyze the data of 436 listed firms from the Chinese Shenzhen Stock Exchange. The result of this study indicates there is a positive relationship between the firm size and the quantity of accountants employed by the firm. The study also establishes the multiple regression equation, which can be used to predict the quantity of accountants of listed firms. And it provides a way to predict the quantity of accountants of legal organizations. 相似文献

Risk-based classification of supplier relationships 总被引:2,自引:0,他引:2

The management and exploitation of external resources has increased and become a new source of business success. This has given rise to various new risks and therefore increased the need for collaborative risk management and learning. The objective of this paper is to explore the differences in risk management and learning across supplier relationships classified through network risks. The paper provides a theoretical review of supplier relationships and risk management, as well as a survey-based empirical study conducted in one case company's supply network. A set of network risks and risk-management measures is developed by means of factor analysis, and a supplier classification by means of cluster analysis. According to the results, the exploitation of collaborative risk management and learning is highest among the most strategic supplier relationships. A classification typology based on suppliers’ opinions helps both parties in the relationship and enables the efficient exploitation of mutual risk management with collaborative learning as one of its keystones. 相似文献

The debate about the Prebisch-Singer thesis has focused on primary commodities with some extensions to manufactures. We analyse trends in country terms-of-trade for goods and services rather than those for commodities according to the World Bank income classification. We find that the natural logarithm of the terms of trade for all groups except for the poorest has common unit roots, but none has individual unit roots. As low-income countries have no unit roots over-differencing is inefficient and biases significance levels in first differences against the fall in the terms of trade. For the low-income countries the terms of trade of goods and services are falling at a rate that is significantly negative without and with endogeneity treatment by system GMM. A comprehensive analysis of the effects of time dummies supports the result of falling terms of trade for low-income countries. When all coefficients are country-specific 50% of all low-income countries have falling terms of trade in a simultaneous equation estimation using the SUR method. Food and financial crisis have no effect on the number of countries with falling terms of trade, but (dis-)improve the terms of trade or the significance of the results for a very small number of countries. 相似文献

Japan has been in a benign liquidity trap since the 1990s. In a benign liquidity trap, interest rates approach zero and monetary policy is ineffective but output and employment perform decently. Such a pattern contradicts traditional macro theories. This paper introduces a monetary general equilibrium model that is compatible with Japan's performance and resolves puzzles associated with liquidity traps. Possible conclusions for Anglo‐Saxon countries and eurozone members are also discussed. 相似文献

I examine whether the volume-synchronized probability of informed trading (VPIN) can predict a flash crash in the yen/dollar foreign exchange market. The results show that VPIN using bulk volume classification predicted a recent event. However, VPIN using order flows, which are the amount of the ask-side transaction minus those of bid-side, does not. 相似文献

In this paper, we consider a continuum economy with a finite number of types of agent, and several private and public goods. The main result of the paper is that the graph of the equal-treatment Lindahl equilibria mapping is the unique abstract stable set with respect to the dominance relation in economies with crowding effects introduced by Vasil'ev et al. in 1995. The external stability of this mapping implies that, for any equal-treatment allocation x in , that is not a Lindahl equilibrium, there exists a subeconomy of such that one of its equal-treatment Lindahl allocations blocks x. This result is a counterpart of the theorem of Mas-Colell for Aumann's atomless market with private goods. 相似文献

This paper defines and characterizes essential decentralized networks for calculating the associative aggregate of one or
more cohorts of data. A network is essential if it is not possible to eliminate an instruction or manager and still calulate
the aggregate of each cohort. We show that for essential networks, the graphs that depict the operations and data dependencies
are trees or forests. These results assist in the characterization of efficient networks.
