A resilience perspective of the SEEA

While the SEEA is an important advance in national accounting it remains deficient in a number of ways in regard to natural resources. The dynamic and interactive nature of ecosystems means that any linear, compartmentalised system of accounting will miss significant changes that influence human wellbeing. In particular, losses in resilience of critical capital stocks (through changes in underlying ecosystem variables that do not contribute directly to valued flows, and are therefore not included in the accounts) means that the accounts will not recognise that such stocks are becoming riskier, likely to collapse, and are therefore over‐valued. We present a stock‐based approach to measuring sustainable development (the Inclusive Wealth Approach of [Arrow KJ, Dasgupta P and Maler K‐G. (2003) Evaluating projects and assessing sustainable development in imperfect economies, Environmental and Resource Economics, 26:647-685]) at a regional scale, using an example from South East Australia, which includes an assessment of the resilience of critical capital stocks.     

Inflation,financial development,and growth: A trilateral analysis

A large body of evidence links financial development to economic growth, yet the channels through which inflation affects this relationship and its stability have been less thoroughly explored. We take an econometric and graphical approach to examining these channels, and find that higher levels of financial development, combined with low-inflation, are related to higher rates of economic growth, especially in lower income countries, but that financial development loses much of its explanatory power in the presence of high-inflation. In particular, small increases in the price level seem able to wipe out relatively large growth effects of financial deepening when the annual rate of inflation lies between 4% and 19%, whereas the operation of the finance–growth link is less affected by inflation rates above this range. Growth is generally much lower, however, in such high-inflation settings where financial development is typically repressed.     

Do Foreign Greenfields Outperform Foreign Acquisitions or Vice Versa? An Institutional Perspective

abstract Prior studies of the comparative performance of greenfields and acquisitions have advanced competing arguments, with some arguing that greenfields should outperform acquisitions because acquisitions are costlier to integrate, and others that acquisitions should outperform greenfields because greenfields suffer from a liability of newness. Moreover, while the costs of integration and the liability of newness are at their greatest during a subsidiary's first years, prior studies have tested their competing arguments on samples containing older subsidiaries. We extend these prior studies by (1) developing an institutional theory‐based framework that simultaneously considers the costs of integration and the liability of newness, (2) recognizing that both types of costs vary with the level of subsidiary integration, and (3) focusing on the stage of their life during which subsidiaries predominantly incur these costs. To measure subsidiary performance, we ask managers of Dutch multinationals how their ex ante performance expectations compare to the subsidiary's ex post performance during its first two years. Analysing a sample of 191 foreign subsidiaries and controlling for entry mode self‐selection and other factors, we find that acquisitions outperform greenfields at low and intermediate levels of subsidiary integration, but that greenfields outperform acquisitions at higher integration levels.     

Cigarette pack and advertising displays at point of purchase: community demand for restrictions

Tobacco promotion influences tobacco consumption. Traditional forms of tobacco promotion have been heavily restricted in response to the harmful effects of tobacco. Tobacco displays at the point of purchase are increasingly important as a means of communicating brand imagery for the tobacco industry, especially when advertising is restricted at these points. Previous research has demonstrated that children exposed to tobacco advertising at the point of purchase have inflated perceptions of availability, use and popularity of tobacco. Internationally, laws are being debated and implemented to prohibit or restrict the display of tobacco at the point of purchase or put tobacco out of sight. Such measures would reduce tobacco product exposure and, hence, tobacco marketing among youth and the community. In South Australia, a ban on all cigarette advertising at the point of purchase was introduced in 2005. This study was designed to assess community support for restrictions on cigarette displays and advertising at the point of purchase. A telephone survey was conducted with a random sample of 2026 South Australian adults (aged 18 years and over) in July 2005. Overall, 63% of the community approved of a hypothetical total ban on cigarette displays at the point of purchase, with over three‐quarters believing this should happen in the next 12 months. A further 24% believed that cigarette displays should be restricted and 82% would approve of a ban on displays in stores that sell confectionary. Only 7% of adult smokers reported making their decision about the brand of cigarettes to buy at the point of purchase and 90% made their decision before they even entered the shop. The results strengthen arguments that cigarette displays are not necessary to maintain brand loyalty or to encourage brand switching of established smokers. Instead, the results make arguments more credible that cigarette displays normalize and promote smoking among young people and may also promote unplanned purchase or increased consumption among less frequent smokers or former smokers. Placing cigarettes out of sight would be unlikely to impact on brand choice for most smokers, who have already made up their mind before they enter the store.     

Dealing with a Lead User’s Demand for Product Development

This article focuses on product development in interaction. Two types of -product development projects demanded by a lead-user type of customer are discussed, as well as the consequences these projects have for the supplier regarding change in production processes, market risk and relationship dependencies. The discussion is illustrated by two cases. Six propositions are developed and further research suggested.

     

Momentum profits in the Australian equity market: A matched firm approach

This paper examines momentum trading strategies within the Australian equity market over the period 1990 to 2007, inclusive. We analyse excess returns employing both Jegadeesh and Titman's (Jegadeesh, N., Titman, S., 1993. “Returns to buying winners and selling losers: implications for stock market efficiency”. The Journal of Finance, 48:65–91) zero cost investment portfolio approach and a matched control firm approach. We also allow for short sale restrictions, liquidity constraints and transaction costs in the form of bid-ask spreads. Testing reveals that both the Jegadeesh and Titman (Jegadeesh, N., and Titman, S. (1993). “Returns to buying winners and selling losers: implications for stock market efficiency”. The Journal of Finance, 48:65–91.) zero cost investment portfolio approach and the matched control firm approach yield excess profits. While the implementation of short sale restraints increases momentum profitability, the subsequent inclusion of bid-ask spreads results in a reduction in these gains. Further, we find that executing a momentum strategy in Australia results in statistically significant dollar profits.
