This paper provides evidence of how a transition to IFRS affects key financial ratios and the pertinent financial statement items. Building on Lantto and Sahlström's (2009) evidence from creditor-oriented code law regimes, we examine the impact of IFRS transition on listed companies in the shareholder-oriented common law regime of the UK. The study contributes two insights: First – despite their similarities – conversion from the UK General Accepted Accounting Principles (GAAP) to IFRS leads to substantial differences in key financial ratios. These even surpass differences reported by companies in creditor-oriented code law regimes. We find that medians of profitability ratios increased substantially: Operating Income Margin (OPM) increased by 10.8%, Return on Equity (ROE) by 27.0%, and Return on Invested Capital (ROIC) by 14.4%. The Current Ratio (CR) and Price-to-Earnings (P/E) Ratio also exhibit significant but less drastic changes of 4.2% and − 2.9%, respectively. Second, differences in shareholder-oriented common law regimes have the same causes as in creditor-oriented code law regimes, i.e., an increase in Operating Income, Net Income, Current Liabilities and Invested Capital, as well as a decrease in Shareholder Equity. 相似文献

This article reflects on existing and emerging future challenges arising in the area of “evolutionary business information systems”, a class of systems that demand an evolutionary software development process and which support secondary design of various conceptual layers. We place both existing contributions and future research opportunities in context by referring to an idealized, preliminary system architecture. Finally, we emphasize our pluralistic perspective on the research object and the resulting need for methodological flexibility in the sense of interdisciplinary configurations of research methods. 相似文献

This article describes a cost analysis of an employment programme available to people claiming incapacity benefits in the UK. The NDDP was delivered locally by contracted providers called ‘job brokers’. The cost analysis found great variation among job brokers' costs and profitability, much of which seems attributable to differences in job broker size. The methods described here will be useful in evaluations wherever multiple institutions are contracted by governments to deliver services, especially when these institutions are involved in several different programmes. 相似文献

The effect of privatization on wealth distribution in Russia 总被引:1,自引:0,他引:1
Michael Alexeev 《Economics of Transition》1999,7(2):449-465
The paper considers the Russian privatization process and examines how its deviation from the competitive sale standard was likely to affect wealth inequality. (Privatization here is defined narrowly as the transfer of existing assets from government ownership to private hands.) While empirical evaluation is all but impossible due to the dearth of reliable data, it is feasible to analyze the institutional features of Russian privatization in terms of their effect on redistribution of wealth. The paper argues that the most relevant and interesting issue is to evaluate privatization's distributional consequences relative to the informal pre-reform property rights. In light of this, privatization is modelled as a rent-seeking contest with incumbency advantage of enterprise managers who initially held the greatest informal rights over assets. The rent-seeking contest is shown to strongly magnify this pre-reform wealth inequality reflected in the incumbency advantage.
In addition, the paper analyzes the distributional consequences for various wealth groups of the differences in the composition of their pre-reform informal wealth, most importantly a relatively large share of housing assets in the wealth of the poor. The effect of wealth redistribution on economic growth in Russia is also discussed. 相似文献
