THE APPLICATION OF SIMULATION TECHNIQUES TO THE STUDY OF GRAZING SYSTEMS

Decision making studies in agriculture are often made difficult by the complex and dynamic nature of bio-economic systems. Simulation is one of the newer systems research techniques which as yet has had limited use in farm management research. This paper discusses some methodological aspects of simulation with specific reference to grazing systems. Problems arising in the development and use of simulation models are discussed and the need for inter-disciplinary co-operation to overcome data problems is indicated. One approach to experimentation is illustrated by reference to a model of a sheep grazing system and the problem of cropping for winter grazing. It is concluded that simulation is a potentially useful technique for management-oriented systems research in agriculture.     

Accelerated Product Introductions and Emerging Managerial Accounting Perspectives: Implications for Marketing Managers in the Technology Sector

Rapid changes in manufacturing and design technologies coupled with increased competition domestically and internationally have led to shorter product life cycles and compressed lead times for product introductions in the technology sector. Traditional cost accounting systems, which assume labor to be the major cost component in the production process, have resulted in distortions in cost information. Samuel Rabino and Arnold Wright describe emerging cost accounting approaches that more adequately address the changing competitive and technological environments and facilitate an improved evaluation of product launch programs.     

The impact of competition on the operations of foreign banks in Australia in the post-deregulation period

In 1985, Australia removed its long-standing embargo on the entry of foreign banks. The Australian market therefore provides an opportunity to study the factors influencing multinational bank expansion in a new host country. This paper tests a model of the size of multinational banking operations in Australia in the post-embargo period. One major finding is that a push for market share in a highly competitive environment led to risky lending practices in the global boom-bust economic climate of the late 1980s, which adversely affected the foreign banks’ performance. Another is that competition from home country banks had a significantly negative effect on foreign banks’ asset volumes.     

Operating cash flow asymmetric timeliness in Australia

Operating cash flow (CFO) asymmetric timeliness occurs when CFO reflects bad news more quickly than good news. We examine the presence and determinants of CFO asymmetric timeliness in Australia, where substantial differences in reporting requirements of cash flow components, in characteristics of listed companies and in the degree of conservative financial reporting produce contrasting findings to those in the United States. We find supportive evidence for the novel ‘sticky cost behaviour’ explanation and also the product-pricing strategy, but not the life cycle hypothesis. These findings are useful for investors and analysts concerned with forecasting the future values of companies.     

Real-Time Pricing and Imperfect Competition in Electricity Markets*

We analyze the effects of the adoption of real-time pricing (RTP) of electricity when generating firms have market power. We find that an increase in consumers on RTP contracts decreases peak prices and increases off-peak prices, increases consumer surplus (both for switching and non-switching consumers) and welfare, while decreasing industry profits, with these effects being magnified by the extent of market power. We illustrate these results by calibrating our model to the New Zealand electricity market, and find that taking into account the market power of generating firms increases the efficiency gains from RTP adoption by 41%.     

THE EFFECTS OF NEWS WHEN LIQUIDITY MATTERS

We analyze the impact of news (information shocks) in economies where liquidity matters, including those with endogenous credit limits, and those with assets serving as collateral or media of exchange. Although we also consider news about productivity and credit conditions, a leading case concerns monetary policy announcements. Real or monetary news has big effects on markets, potentially causing cyclic or boom–bust responses, even though we focus on the unique transition consistent with stationarity after shocks. In particular, policy announcements may induce instead of reduce volatility. We also discuss the implications for the inflation puzzle, forward-guidance puzzle, and other apparent anomalies.     

Has Adoption of IFRS Increased Non–North American Institutional Investment in the Canadian Stock Markets?

We investigate whether non–North American (non‐NA) institutional investment in firms listed on the Canadian stock markets increased between the pre‐ and post‐IFRS adoption periods relative to such investment in firms listed on the U.S. stock markets. Prior to IFRS adoption, Canada had high‐quality financial reporting standards that were similar to the U.S. standards. As consequences of IFRS adoption, Canadian financial statements became more comparable with European and other IFRS country financial statements and less comparable with neighboring U.S. financial statements. Thus, a question of interest is whether the enhanced comparability with non‐NA companies was beneficial in terms of attracting non‐NA investment to Canadian companies versus U.S. companies. We find that there was no significant change in non‐NA institutional investment in Canadian firms relative to U.S. firms for the very largest (fifth quintile) and for smaller (first, second, and third quintiles) Canadian companies. However, intermediate‐sized Canadian companies in the fourth size quintile lost non‐NA institutional investment relative to their U.S. peer companies, suggesting that non‐NA investors cared more about comparability with U.S. peer companies than non‐NA peer companies for companies in this size quintile.
