Intellectual Property Government Open Data: Australian Business Number Links to All Intellectual Property Data in Australia

Intellectual property rights protect the fruits of investment in intangible assets, such as inventions and innovations, creative content, designs, brand recognition and reputation, through five broad arms: patents, trade marks, design rights, plant breeder's rights and copyright. All of these rights, with the exception of copyright, are administered by IP Australia. To facilitate analysis of these rights, IP Australia released Intellectual Property Government Open Data (IPGOD) on < data.gov.au >. IPGOD is a weekly updated, publically accessible database that provides access to 100‐plus years of non‐sensitive administrative data on intellectual property rights held in IP Australia's databases that are linked to Australian Business Numbers and Australian Company Numbers.     

Sentiment effects on Chinese share prices and savings deposits: The post-2003 experience

This paper examines the importance of sentiment effects on asset allocation decisions in mainland China and beyond. Rising stock market sentiment appears to have negatively and significantly impacted Chinese savings account growth over the 2003–2007 period. Investor sentiment also exerted consistently significant effects on the discounts attached to Chinese B-shares, H-shares and ADRs by foreign investors. Although the sample period is limited by availability of the sentiment data, the indicated effects remain most robust when controlling for relative stock market performance, liquidity levels, expected exchange rate movements, and such ‘indirect’ sentiment measures as market and firm-specific price-earnings ratios.     

The Effect of Mortgage Price and Default Risk on Mortgage Spreads

Variations over time in mortgage yield spreads should reflect changes in the underlying prepayment option value; moreover, the relationship between mortgage yield spreads and interest rate dynamics should weaken as the value of the borrowers prepayment option declines. We verify this hypothesis through an empirical analysis of residential mortgage yield spread behavior, and we also present evidence that the strength of the relationship between mortgage spreads and interest rate dynamics weakens (strengthens) as the level of default risk increases (decreases). This result is consistent with the competing risks effect between a borrowers option to prepay or default. Our results demonstrate the importance of accounting for mortgage price discount to par as well as default risk when developing time series of mortgage yields.     

Imported Intermediates,Absorptive Capacity and Productivity: Evidence from Ghanaian Manufacturing Firms

This paper analyses whether the use of imported intermediates improves productivity using firm‐level panel data of manufacturing firms in Ghana covering the period between 1991 and 2002. This includes examining the importance of absorptive capacity (ABC) in enhancing the productivity gains from imported intermediates. We propose lagged relative productivity as a new measure of ABC. For any given period, ABC is defined as the natural logarithm of a firm's total factor productivity (TFP) in the previous period relative to the firm's initial TFP. An alternative measure of ABC considers real value added per worker in lieu of TFP. Overall, we find that firms with high levels of ABC derive productivity gains from the contemporaneous and prior use of imported intermediates, particularly for firms operating in the input‐intensive industries. Our findings are robust to different specifications of the base model and different estimation techniques.     

Central Bank Intervention,Exchange Rate Regime and the Purchasing Power Parity

Motivated by the argument that central bank intervention leads to non‐linear exchange rate adjustment processes, we examine purchase power parity (PPP) by applying quantile unit root tests to the exchange rates of the New Taiwan Dollar (NTD) vis‐à‐vis seven Asian currencies. We show that exchange rate regime matters in determining whether PPP holds. While PPP holds overwhelmingly during the period when the NTD is under the fixed exchange rate regime, it is present only for some exchange rates during the managed floating rate regime. For exchange rates exhibiting mean reversion, the reversion occurs mainly when the shocks are large. In contrast to conclusion in the literature, our test results show little evidence of asymmetric mean reversion between positive and negative shocks.     

Credibility of corporate announcements and market reaction: evidence from Canadian share repurchase programs

Do market participants evaluate the credibility of a firm's share repurchase announcement based on the firm's share repurchase history? Using a sample of 1,507 share repurchase programs for firms listed on the Toronto Stock Exchange from 1994 to 2005, we find that 69% of firms fail to acquire the target number of shares specified at announcement and many firms fail to repurchase any shares. We develop credibility indices and find a positive relationship between current announcement abnormal returns and completion credibility of previous announcements. We conclude that the market prices completion credibility of past share repurchase announcements in reacting to current repurchase announcements. Copyright © 2010 ASAC.

A Bayesian Model for Estimating Census Undercount,Taking Emigration Data from Foreign Censuses*

The new method of measuring net undercount in a census of population is a variant of demographic analysis and is founded in the belief that the most reliable counts of people are the counts of births and deaths. It has been applied to the 1991 census of England and Wales (E&W). The method has two distinctive features. The first is that it bases its estimates of numbers of emigrants on figures of persons born here and recorded as residents in the 1990–91 censuses of other countries. The corresponding data on immigrants are taken from our own census. The method does not therefore require the data on migratory flows that are an essential component of conventional demographic analysis. The second feature is the Bayesian approach in which (1) each of 30 uncertain elements in the calculations is given an a priori error distribution and (2) three empirical constraints are imposed on the sex-age profile of percentage net undercount. This, in conjunction with a Monte Carlo process, generates an error distribution for net undercount. These merits of the method are offset by the demerit that the calculations must await results from the censuses of the other countries in which substantial numbers of our emigrants reside.     

Cabri Project—a Collaborative Research Facility

This paper describes the results of a case-study carried out within the context of a wider evaluation of the benefits and costs of international collaboration in Europe for the development of fast breeder reactors. The Cabri reactor is a large scale research facility jointly owned and operated by France and Germany, with the UK, USA, and Japan involved as junior partners. The organisation of the collaboration is discussed. Particular issues include problems surrounding barter arrange- ments, personnel aspects and the extent to which costs and benefits have been incurred. It is concluded that a substantial saving was achieved compared with performing the work in one country, but at a cost of reduced national control. The collaboration was facilitated by the lack of immediate commercial significance and by the organisational structure.
