Development in Information and Communications Technology (ICT) Statistics at the Australian Bureau of Statistics

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field.

我国商品流通的变迁与发展趋势

计划体制下形成的是与高度集权的经济体制相适应的分配式商品流通组织体系。转轨时期商品流通呈现“三多一少”的格局，流通的低层次性和非系统化。未来的商品流通呈现出弱化二元经济特征、批发业革新、信息化等趋势。     

Commodity currencies

This paper looks at real exchange rate behavior by focusing on three OECD economies (Australia, Canada, and New Zealand) where primary commodities constitute a significant share of their exports. For Australia and New Zealand especially, we find that the US dollar price of their commodity exports (generally exogenous to these small economies) has a strong and stable influence on their floating real rates, with the magnitude of the effects consistent with predictions of standard theoretical models. However, after controlling for commodity price shocks, there is still a purchasing power parity puzzle in the residual. The results here are relevant to developing commodity-exporting countries as they liberalize their capital markets and move towards floating exchange rates.

Trade matters except to war neighbors: The international stock market reaction to 2022 Russia’s invasion of Ukraine

We investigate the role of international trade and proximity to war in international stock markets during the invasion of Ukraine by employing DiD designs and panel data comprising 70 stock markets. We find that differences in trade exposure to warring countries (trade effect) have a substantial and negative impact on non-European equity markets but are irrelevant for European markets. In contrast, differences in the distance to warring countries (proximity effect) have a significant and negative impact on European markets but have no bearing on non-European markets. We find that the relevance of rent from mineral, natural gas, and oil resources and the relevance of metals, ores, and fuels in exports operate as mitigators of the trade effect. Our paper provides valuable empirical evidence regarding the importance of mitigating the vulnerability of financial markets to international trade when a major war breaks out.     

云南少数民族地区可持续发展理念的形成和发展

在自然经济模式下,人们对资源的开发和利用十分有限,经济发展水平低,交流范围狭窄,因此,可持续性和生态平衡得以较好地维系。改革开放以来,特别是国家确立了建立社会主义市场经济体制的目标模式之后,少数民族地区的商品经济均有不同程度的发展,在国家确立了西部大开发和全面建设小康社会的战略目标之后,少数民族地区商品经济迅速发展起来。商品经济的发展对生态平衡和可持续性带来了前所来有的冲击,如何通过制度安排和技术手段来发展经济的同时保持生态平衡,实现可持续发展是少数民族地区经济发展面临的一个两难选择,为解决发展和保护之间的矛盾,云南少数民族地区可持续发展的理念便逐渐形成和发展起来。     

Noisy chaotic dynamics in commodity markets

The nonlinear testing and modeling of economic and financial time series has increased substantially in recent years, enabling us to better understand market and price behavior, risk and the formation of expectations. Such tests have also been applied to commodity market behavior, providing evidence of heteroskedasticity, chaos, long memory, cyclicity, etc. The present evaluation of futures price behavior confirms that the resulting price movements can be random, suggesting noisy chaotic behavior. Prices could thus follow a mean process that is dynamic chaotic, coupled with a variance that follows a GARCH process. Our conclusion is that models of this type could be constructed to assist in forecasting prices in the short run but not over long run time periods.First version received: June 2001/Final version received: March 2003     

Commodity price cycles and heterogeneous speculators: a STAR–GARCH model

We propose an empirical commodity market model with heterogeneous speculators. While the power of trend-extrapolating chartists is constant over time, the symmetric impact of stabilizing fundamentalists adjusts endogenously according to market circumstances: Using monthly data for various commodities such as cotton, sugar or zinc, our STAR–GARCH model indicates that their influence positively depends on the distance between the commodity price and its long-run equilibrium value. Fundamentalists seem to become more and more convinced that mean reversion will set in as the mispricing enlarges. Commodity price cycles may thus emerge due to the nonlinear interplay between different trader types.
