Towards the Development of a Tax System Complexity Index

Reducing tax system complexity is a common goal amongst policymakers; yet there is no commonly agreed definition of complexity. This paper seeks to fill this gap, by proposing the construction of an index of tax system complexity, conceived as a summary indicator of the overall complexity of a tax system at a particular point in time. If adopted, such an index would not only enable assessment of the changing level of a country's tax system complexity over time, but may also facilitate comparisons of the relative complexity of different countries' tax systems in future.     

A Note on a Conversation with Geoff Harcourt

In this note Geoff Harcourt offers his views, via a face to face interview, on a wide range of issues relating to the discipline of economics. He recalls his time as a student at University of Melbourne, his choice of doctoral study and experiences at University of Cambridge, his original intellectual influences and affiliation, and his contributions to economics. He also discusses how economics have evolved over the years, comments on the current status of economic teaching, research and policy advice in Australia, and makes some recommendations to early career researchers. The note also includes a brief bio sketch of Professor Harcourt.     

Tax Non-Compliance and Perceptions of Corruption: Policy Implications for Developing Countries

Tax non-compliance and perceptions of corruption are key challenges to state-building in developing countries. Using a social psychology approach, we develop a theoretical model in which different forms of perceived corruption can adversely influence the way individual taxpayers behave. We then apply this model to Indonesia, placing our empirical findings in the context of compliance risk management, identifying strategies to improve tax compliance, and exploring how to implement these strategies effectively. We shed light on the applicability of the traditional responsive regulatory approach (used by revenue authorities to deal with intentionally non-compliant taxpayers), which combines measures in attempting to achieve either voluntary or enforced compliance. While the empirical evidence is based on the Indonesian experience, we suggest that our model is sufficiently general and robust to be applicable to other developing countries in the Asia-Pacific region.     

The Causal Effect of Retirement on Health: Understanding the Mechanisms

This article examines the direct effects of retirement on health, as well as its indirect effects, through a mediation analysis. Using Australian panel data, analysis reveals that changes in retirement status and retirement duration imply positive causal effects on self‐assessed health as well as physical health and mental health. Gender plays an important role in shaping these relationships. For women, the positive relationship between retirement duration and health can be attributed to physical activity. In contrast, men appear to enjoy better health when staying retired for longer because they participate more in outdoor activities.     

Business responses to climate change: strategies for reducing greenhouse gas emissions in Vietnam

This study identifies the climate change strategies adopted by firms in developing countries to reduce their greenhouse gas (GHG) emissions. First, a framework is developed to classify and assess the GHG emission strategies of companies; second, it is then improved by using data on their implementation collected from 185 companies operating in 10 energy-intensive industries in Vietnam. We find that multinational subsidiaries engage in various climate change activities and have a higher level of implementation than those of domestic firms. Further, the most active and proactive companies are large in size and from Europe, the United States and Japan.     

Meeting the Challenges for Franchising in Developing Countries: The Vietnamese Experience

While business format franchising is the industry standard for developed countries, it remains an aspiration for many developing countries. Despite the attraction for developing countries of systems, training, and support and despite the economic and regulatory infrastructure being in place for the development of business format franchising, a range of commercial and socio-cultural factors may conspire to prevent its full expression. This paper addresses franchising development in Vietnam, a developing country. It considers strategies to bridge the gap between Vietnamese franchise practice and franchising best practice. It proposes that in Vietnam's current state of development, the product and trade name model may be the appropriate starting point with a move to the business format model only when, and in places where, the socio-cultural, commercial, and economic factors and the legal environment can accommodate more sophisticated business format franchise arrangements.     

Good Morning,Vietnam! Opportunities and Challenges in a Developing Franchise Sector

Until recently the development of franchising in Vietnam was hampered by a regulatory framework that did not recognize franchising as a discrete business relationship. The introduction of Vietnam's Franchise Law in 2005 provided, for the first time, a legal foundation for franchising, which was a necessary prerequisite for sector development. Although there are currently few business format franchise systems operating in Vietnam, there is an increasing presence of established international franchise systems and increasing numbers of local systems albeit at an early “product distribution” evolutionary stage. Moreover, the commercial environment for franchising is increasingly favorable: Vietnam is the fastest growing Asian economy after China and India and is experiencing strong gross domestic product growth and annual retail growth. This article addresses the development of franchising, and the challenges and opportunities for franchisers in Vietnam.     

Human capital and economic growth in an overlapping generations model

The paper describes an aggregative optimal growth model, the essential features of which are that individuals are mortal and obtain their labor skill through educational training. The process of human capital formation is described by an education function which relates the pass rate to the educational expenditure per student. Two alternative scenarios, private and public education regimes, are separately investigated. Under the decentralized education regime, risk-neutral individuals borrow to finance their education when young. Under the centralized education regime, the cost of education is financed by taxes imposed on the workers in the economy, and the central government maximizes a long-term social target function. The equilibria of both regimes are analyzed and various comparative static results derived. It is shown that educational investment in a decentralized equilibrium is higher than that in the centralized steady state. We also establish that there exists a time discount rate at which or above which the decentralized per capita consumption exceeds that of the centralized steady state whereas for time rates of discount sufficiently near the population growth rate, the above result will be reversed.     

Do futures‐based strategies enhance dynamic portfolio insurance?

In this paper we investigate the relative performance of two approaches to dynamic portfolio insurance: the synthetic put and the Constant Proportion Portfolio Insurance (CPPI). The investigation is conducted on the Australian market, over a sample period of 59 non‐overlapping quarters from December 1987 to December 2002. Its main contribution is to provide a comprehensive assessment of the two approaches under different market conditions, and the testing of ex ante information as an input into the trading program. The major finding is that the futures‐based implementation of both synthetic put and the CPPI approach is robust to both tranquil and turbulent market conditions in preserving the desired floor. The fact that this conclusion includes the case of employing implied volatility (obtained from the options market) is highly encouraging as it suggests high implementability of the strategy. Notably, the risk‐return tradeoff shows that portfolio insurance using this volatility measure yields a return that is 64 basis points over the risk free investment. © 2004 Wiley Periodicals, Inc.
