Is exchange rate stability beneficial for stabilizing consumer prices in China?

This study examines the relationship between real effective exchange rates (REERs) and the consumer price index (CPI) in China, utilizing a bootstrap Granger full-sample causality test and a sub-sample rolling-window estimation. Considering structural changes, we assess the stability of the parameters and find that both the short-run and long-run relationships between the two estimated variables are unstable. This result suggests that full-sample causality tests cannot be relied upon. We instead employ a time-varying (bootstrap) rolling-window approach to revisit the dynamic causal relationship, and we find that the CPI is affected by the REER for several sub-samples due to the role of exchange rate pass-through (ERPT) under the managed floating exchange rate regime in China. These findings provide further proof of the impact of stable exchange rates on the maintenance of relatively steady price levels especially during the economic crisis and economic reform in China. The policy implication of these findings is that maintaining exchange rate stability is beneficial for controlling inflation during the economic crisis and economic reform.

Demand-following or supply-leading? Trade openness and financial development in China

This study explores the causal relationship between financial development and trade openness in China, using the research methodology namely bootstrap Granger full-sample causality test and sub-sample rolling-window estimation. The results reveal that there is a significant bidirectional relationship between financial development and trade openness in China, pointing out the existence of both ‘demand-following’ and ‘supply-leading’ hypotheses. Furthermore, their relationship fits well the fact that China has experienced economic restructuring and structural changes in the past few decades. As financial development improves trade openness robustly, the Chinese policymakers should further increase financial reform to promote trade development.     

More than window dressing: visual merchandising and austerity in London’s West End, 1945–50

Abstract

In the aftermath of the Second World War, the fashion departments of London’s West End department stores were not only challenged by austerity and bomb damage but also by the growth of multiple retailers selling branded ready-to-wear goods. This article investigates how department stores responded by investing in display and visual merchandising to attract custom and rebuild their fashionable reputations. It argues that the difficulties caused by austerity conditions forced department stores to embrace new retail methodologies that helped them adapt to the changed circumstances of post-war fashion retail and compete with multiple retailers.

Corruption and Economic Efficiency: Panel Data Evidence

Abstract

This paper investigates empirically the effect of corruption on countries' economic efficiency. By using a sample of 79 countries for the time period 2000–2006 the paper applies DEA window analysis and econometric panel data techniques. The results reveal that there is a U-shaped relationship between countries' corruption perception levels and economic efficiency. Furthermore, it appears that corruption has a negative effect on countries' economic efficiency. For the first time the turning points of such a relationship are being produced indicating that on average terms and regardless of countries' economic structure, Corruption Perception Index (CPI) above five initiate a positive effect on a countries' economic efficiency.

Accounting Window Dressing and Template Regulation: A Case Study of the Australian Credit Union Industry

This article documents the response of cooperative institutions that were required to adhere to new capital adequacy regulations traditionally geared for profit-maximising organisations. Using data from the Australian credit union industry, we demonstrate that the cooperative philosophy and internal corporate governance structure of cooperatives will lead management to increase capital adequacy ratios through the application of accounting window dressing techniques. This is opposite to the intended purpose of template regulation aimed at efficiently increasing operating margins and lowering risk. Our results raise several debatable issues regarding the ethics of accounting management and the imposition of one-shoe-fits-all external regulation.
