STOCHASTIC ANALYSIS OF INPUT–OUTPUT MULTIPLIERS ON THE BASIS OF USE AND MAKE TABLES

Although technical coefficients are estimated on the basis of flow data (use and make matrices), they are rarely treated as random variables. If this is done, an error term is added to the coefficients, rather than derived from the distribution of the data. Even so, the calculation of multipliers, by means of the Leontief inverse, is difficult. Due to the nonlinearity of this operation, the multiplier estimates are biased. By going back to the flow data, this paper provides unbiased and consistent employment and output multipliers estimates for the Andalusian economy. Rectangular use and make matrices are accommodated and problems associated with the construction and estimation of technical coefficients and the Leontief inverse are circumvented.

Teaching accountants to learn and "building blocks" for accounting education

Conclusions Accounting professionals and academicians have expressed significant interest and are pursuing a variety of changes in accounting curricula. There is a broad range of opinions regarding the nature of the changes needed in accounting education, which range from dramatic redesign to little or no change. There is a need to develop a framework for accounting education that is consistent but flexible to accommodate the majority of the accounting educational needs. The "building blocks" of accounting education presented in this paper provide educators with a basic pedagogical framework for an appropriate learning process. The framework of accounting education specifically focuses on the accounting component of the educational process and identifies the nature of courses and appropriate teaching strategies based upon their goals and objectives. Most educators recognize that only "one" accounting curriculum is insufficient to meet the needs of a variety of constituents. Therefore, it is essential to adopt an appropriate general framework for coursework is adopted to address the development of many diverse accounting programs.     

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.

对现阶段我国现金流通状况的研究

近年来我国现金流通量增长较快且增长幅度不稳定。本文运用协整分析和短期误差修正模型对现金流通状况进行分析得知,长期内现金流量与国内生产总值正相关、与居民消费物价指数负相关;短期内上期的收入波动将影响现期的现金流量。

Sources of gains from international portfolio diversification

This paper looks at the determinants of country and industry specific factors in international portfolio returns using a sample of forty eight countries and thirty nine industries over the last three decades. Country factors have remained relatively stable over the sample period while industry factors have significantly increased during the last decade and dropped again since 2000. The importance of industry and country factors is correlated with measures of economic and financial international integration and development. We find that financial market globalization is the main driving force behind the changes in relative magnitude of the different shocks. Country factors are smaller for countries integrated in world financial markets and have declined as the degree of financial integration and the number of countries pursuing financial liberalization has increased. Higher international financial integration within an industry increases the importance of industry factors in explaining returns. Economic integration of production also helps in explaining returns. Countries with a more specialized production activity have higher country shocks.
