The path of lease resistance: How changes to lease accounting treatment may impact your business

In this installment of Accounting Matters, we examine potential consequences of the Financial Accounting Standards Board's Proposed Accounting Standards Updates for Leases. In the context of a previous accounting change (FIN 48), we investigate how these changes will affect firms’ accounting choices, investment decisions, debt covenant requirements, and analysis of other key financial data. Changes in accounting standards may have significant indirect economic effect on companies as they can trigger debt covenant violations, restrict access to capital, and distort key financial information used by investors and lenders. New accounting standards may also directly affect the calculation of employee bonuses and incentives that utilize EBITDA or operating income as benchmarks. We include recommendations for managers and identify specific debt covenant components that may limit the negative consequences of the proposed change to lease accounting.     

The Impact Of Computer Prices On International Comparisons Of Labour Productivity

This paper analyses the international comparability of methods used to convert the value added of the office and computing machinery sector (OCM) into constant prices for nine OECD countries. It concludes that the variations which exist in the price indexes are largely due to differences in the methods countries use to capture changes in the quality of an industry's output over time. The paper evaluates the impact of these different OCM price indexes on the growth rate of labour productivity during the 1980s by conducting a sensitivity test where the US OCM index is substituted for each of the individual country indexes. This experiment causes the OCM labour productivity growth rate to change by over a factor of ten for several countries. This result suggests that international comparisons of labour productivity should not be made for the OCM sector using the official data, and that labour productivity comparisons of sectors OCM belongs to—non-electrical machinery and fabricated metal products and machinery—should be conducted cautiously, if at all.     

Shopping East and Shopping West—Chinese Consumer Behavior in Two Worlds

ABSTRACT

In today's China, consumers not only have the chance to sample products and services from around the world, but to experience cultural influences from a vast range of countries. In particular, Western products and services—and cultural values—have become increasingly popular. Consumers now shift between different worlds (Chinese and Western) with seeming ease. This research identifies the factors that encourage consumers to shift between these different worlds—and values. The factors include the situation and context (of the shopping experience), peer influence and dynamics, the role of conversation at or near the time of purchase, and the nature of the product and service. The role of “time,” “chance,” and “intuition” in the shopping experience and cultural shifts are also examined. What emerges from the study is a changeable, mobile, and flexible community quite capable of shifting between different sets of values (and consumer attitudes) easily and often very quickly. For companies, the key to success (at least to some degree) is to place their goods and services in a context that helps to create a complementary, integrated, and supportive image of the world they wish to create in the minds of their Chinese consumers.
