The public R&D and productivity growth in Australia's broadacre agriculture: is there a link?

This paper investigates the dynamic relationships between research and development (R&D) expenditure and productivity growth in Australian broadacre agriculture using aggregate time series data for the period 1953 to 2009. The results show a cointegrating relationship between R&D and productivity growth and a unidirectional causality from R&D to TFP (total factor productivity) growth in Australian broadacre agriculture. Using the dynamic properties of the model, data from beyond the sample period are analysed by employing the variance decomposition and the impulse response function. The findings reveal that R&D can be readily linked to the variation in productivity growth beyond the sample period. Furthermore, the forecasting results indicate that a significant out‐of‐sample relationship exists between public R&D and productivity in broadacre agriculture.     

Beach safety education for primary school children

Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus.     

Some Evidence on the Relevance of Bank Behaviour for the Lending Channel in The Netherlands

This paper studies the behaviour of Dutch banks. We test the adjustment of banks' balance sheets in times of monetary policy changes during the period 1957–1991. As a reaction to a policy change, banks basically have two alternatives to adjust their net money creation: (1) sell securities in public capital markets, and/or issue long-term liabilities, and (2) change domestic loan supply. If banks opt for the latter a lending channel may be relevant, even in a small open economy with a fixed exchange rate and a high degree of international capital mobility. We test for the effectiveness of both indirect and direct instruments of monetary policy. It turns out that in case of changes in the official interest rate, the volume of bank loans is not affected and that banks display a kind of buffer-stock behaviour by diminishing their publicly traded assets. In situations with quantity restrictions on the growth of net money creation, however, the volume of loans is affected significantly when the quantity restriction is withdrawn thereby fulfilling a necessary condition for the bank lending channel to be effective.     

Imputing relevant information from multi-day GPS tracers for retail planning and management using data fusion and context-sensitive learning

It is well known that the right location of shopping centres is of paramount importance. Unless stores succeed in attracting their own clientele, they rely to a large extent on the impulse behaviour of shoppers. To evaluate alternative locations, models of pedestrian behaviour may be useful. Modern technologies such as GPS and RFID offer new possibilities providing data on routes and stops, which are required as input for such models. An automatic interpretation of GPS tracers with respect to the activities being conducted could enhance the applicability of such technologies to retail management applications. This paper reviews this rapidly growing literature, and shows how automatic data imputation can be established by using Bayesian belief networks and how GPS traces can be fused with land use data of retail location.     

Pace,rhythm, and scope: process dependence in building a profitable multinational corporation

Many potential benefits of foreign expansion have been identified in the literature, yet empirical support that multinational firms perform better than domestic firms is mixed. This paper takes a longitudinal perspective and argues that how much a firm benefits from having foreign subsidiaries depends on its process of internationalization. We argue that a firm's capacity to absorb expansion is subject to constraints: some expansion patterns increase profitability less than others, owing to diseconomies of time compression. We hypothesize that the speed of internationalization, the spread of the geographical and product markets entered, and the irregularity of the expansion pattern negatively moderate a firm's increase in profitability resulting from international expansion. Model estimations based on panel data raised strong support for these predictions. Copyright © 2002 John Wiley & Sons, Ltd.     

International Competition and the Degree of Monopoly in Australian Manufacturing

Pricing behaviour in open economies is examined by adapting Kalecki's analysis of pricing in closed economies. The parameters of the resulting pricing equation are estimated using data for a sample of Australian manufacturing industries. These estimates are then used to calculate measures reflecting the degree of monopoly for an open economy, which are compared with the ratio of aggregate proceeds to aggregate direct costs as a measure reflecting the degree of monopoly for a closed economy.
