A multiregional model of China and its application

China's rapid economic transformation since 1979 has been accompanied by a stark regional disparity with the coastal provinces integrating swiftly into the world markets while inland regions lagging far behind in the industrialisation process. The growth imbalance has placed China's provinces into different stages of development and called for different policy responses to deal with different challenges they are facing. Similarly, a national policy initiated by the central government is likely to be interpreted and implemented in different ways when local governments take into consideration the different conditions in their localities. Therefore, it would be extremely valuable for policy makers and researchers to have an analytical tool that is capable of studying interactions among the provincial economies and the dynamic relationship between the centre and local governments. The multiregional econometric model of China presented in this paper is the first attempt to provide such a tool. The pioneering model consists of over 1200 equations, covering 30 provinces of China that are linked by inter-regional flows of goods and services. The model is used to study the impact of fiscal recentralisation in the 1990s. The counterfactual simulation results show that when China's central government diverted tax revenue from provincial governments, it achieved higher budgetary revenue for the central government but at the expense of lower overall budgetary revenue and slower economic growth.

预算控制与企业内部会计控制

预算控制是企业内部会计控制的重要方法之一,我国企业在从粗放管理走向精细化管理的过程中,也正在积极推广全面预算管理.在大量调查的基础上,本文认为,预算控制拓广了传统企业内部会计控制的范围,为会计控制与管理控制的有机结合提供了一个桥梁,其对保证财务报告的可靠性、企业经营活动的合法合规性及提高企业经营的效果和效率既产生了积极的作用,同时,在一定情况下,它又对上述内部控制目标产生消极作用.因此,本文在对预算控制进行正反两方面的分析后,提出了企业在实施预算控制时应注意的问题及应采取的一些措施.

Finite Dimensional Affine Realisations of HJM Models in Terms of Forward Rates and Yields

Finite dimensional Markovian HJM term structure models provide ideal settings for the study of term structure dynamics and interest rate derivatives where the flexibility of the HJM framework and the tractability of Markovian models coexist. Consequently, these models became the focus of a series of papers including Carverhill (1994), Ritchken and Sankarasubramanian (1995), Bhar and Chiarella (1997), Inui and Kijima (1998), de Jong and Santa-Clara (1999), Björk and Svensson (2001) and Chiarella and Kwon (2001a). However, these models usually required the introduction of a large number of state variables which, at first sight, did not appear to have clear links to the market observed quantities, and the explicit realisations of the forward rate curve in terms of the state variables were unclear. In this paper, it is shown that the forward rate curves for these models are affine functions of the state variables, and conversely that the state variables in these models can be expressed as affine functions of a finite number of forward rates or yields. This property is useful, for example, in the estimation of model parameters. The paper also provides explicit formulae for the bond prices in terms of the state variables that generalise the formulae given in Inui and Kijima (1998), and applies the framework to obtain affine representations for a number of popular interest rate models.     

How different is Japanese corporate finance? An investigation of the information content of new security issues

This article studies the shareholder wealth effects associatedwith 875 new security issues in Japan from January 1, 1985,to May 31, 1991. The announcement of convertible debt issueshas a significant positive abnormal return of 1.05 percent.There is an abnormal return of 0.45 percent at the announcementof equity issues that is off-set by an abnormal return of 1.01percent on the issue day. Abnormal returns are negatively relatedto firm size, so that large Japanese firms have abnormal returnsless different from those of U.S. firms than small Japanesefirms. Our evidence is consistent with the view that Japanesemanagers decide to issue shares based on different considerationsthan American managers.
