Valuation and Accounting for Inflation and Foreign Exchange

Inflation and foreign exchange raise new issues with respect to accounting representations of equity value. For example, inflation creates an earnings illusion as an artifact of the mismatching of expenses based on allocations of historical costs with current revenues in determining earnings. This mismatching distorts mappings of aggregate earnings and book values into equity value such that value‐relevant information is lost. In this article we consider the consequences of inflation and foreign exchange accounting policies, including those contained in accounting standards, on the value relevance of bottom‐line accounting numbers. Policies are identified that achieve efficient accounting in the sense that aggregate (comprehensive) earnings and book values are sufficient for an accounting representation of equity value. The linear relations that emerge provide predictions on capitalization coefficients that help explain results of empirical inquiries. As well, our analysis provides a theoretical foundation for policies contained in accounting standards that contributes to the resolution of controversies such as that concerning foreign exchange accounting.     

METROPOLITAN HOUSE PRICES IN SOUTH AFRICA: DO THEY CONVERGE?

The question this paper investigates is whether or not different metropolitan areas each constitute a separate housing market or whether or not there is a single South African housing market. Theory on the Law of One Price suggests that if products or geographic areas belong in the same market, their absolute prices must converge, so that their relative prices are stationary. By using cross-sectional time series data of five metropolitan areas, the paper tests for the Law of One Price by applying the Im, Pesaran and Shin panel unit root test. The paper finds strong evidence of convergence in large middle-segment house prices and weaker support for convergence in medium middle-segment house prices. In addition, the paper finds no evidence for convergence in small middle-segment house prices. This suggests the existence of a national market for large and possibly middle-segment houses in metropolitan areas, but separate metropolitan markets for small middle-segment houses. In addition, the paper estimates the speed of convergence and finds that large middle-segment house prices converge within two to seven quarters, while the speed of convergence for medium middle-segment house prices in three of the five areas is five to eight quarters.

我国社会保障制度模式重构的原则

在社会主义市场经济条件下,重构我国社会保障制度应该坚持法制化原则;普遍加区别原则;合理负担、权利与义务对等原则;与实际国情相结合原则.特别是在依法治国、建设社会主义法治国家基本方略指引下,要特别注重社会保障法律体系的建设.只有法制化的社会保障制度才能保证我国社会主义市场经济良性运作和健康发展.
