International Comparisons of Australia's Infrastructure Performance

International benchmarking has played a key role in the reform of Australia's infrastructure industries by promoting indirect or yardstick competition, in highlighting the need for further reform and building a consensus for implementing necessary changes. The international benchmarking of infrastructure performance by the Bureau of Industry Economics (BIE) between 1991 and 1996 did much to focus attention on the need for change. The BIE examined the performance of eight infrastructure industries relative to international best practice: electricity, rail freight, telecommunications, the waterfront, road freight, coastal shipping, aviation and gas supply. Performance comparisons concentrated on indicators of price, service quality, labour productivity and capital productivity. This paper reviews and summarises the performance comparisons the BIE undertook over the last three years of its infrastructure benchmarking program. The BIE international benchmarking program provides a useful role model for other countries wanting to seriously pursue reform of their infrastructure industries.     

The information content of the Reserve Bank of Australia's inflation forecasts

In this article, the inflation forecasts produced by the Reserve Bank of Australia (RBA) and that generated by private forecasters, are used to assess whether the Reserve Bank possesses information about inflation that the private sector does not have. The results show that the Reserve Bank inflation forecasts embody useful predictive information about inflation, beyond that contained in private forecasts, over the recent inflation targeting period.     

A Note on the Teaching of Economics Through American History

McConnell examines problems connected with measuring the readability of introductory economics textbooks and observes that an index of readability based on sentence length and the number of syllables per some given number of words may be deficient, misleading, and possibly counterproductive. In this connection, he observes that “virtually no work has been undertaken to determine whether the choice of textbook is a significant factor in determining student understanding and performance.” Research in this area might make it possible to substitute empirical evidence for what most instructors in their selection of a textbook attempt to intuit.     

Understanding platform competition through simulation: a research outline

ABSTRACT

Platform competition shapes and is shaped by a constantly changing socioeconomic context. Three trends provide evidence for this: (i) the number of firm level relevant factors for platform success is steadily increasing, (ii) contemporary cases of platform competition take less time to unfold, and (iii) industries converge. These trends suggest that there is a change: in the time required for relevant factors to influence platform competition, and in the trade-offs managers face when they take actions in platform development and competition, to influence the market outcome of such processes. Current frameworks in the literature do not account explicitly for such timing issues. The use of modelling and simulation, along empirical cases, is a way to incorporate timing and strategic action delays in platform competition research. We explore the multi-level research agenda this opens up and develop nine research questions for platform competition research.     

The time cost of food at home: general and food stamp participant profiles

Little is known about the cost of time in food preparation at home. Yet, this economic variable is a common thread running through recent concerns about obesity and the Food Stamp (FS) program. This article provides initial estimates of the time cost in food preparation at home for the United States. Two standard methods of estimation are implemented and three demographic profiles are considered: (i) the general population, (ii) the typical FS participant and (iii) the typical FS participant following the United States Department of Agriculture Thrifty Food Plan. For the general population and averaging across methods, the time cost share of total food cost is about 30% if the individual works in the market and at home, but it is about 49% if the individual does not work in the market. For the typical FS participant, especially one following the Thrifty Food plan, the time cost share of total food cost can be as much as 26% higher than the general population. These substantial percentages provide strong incentives to purchase food away from home and help undermine overall diet quality and the efficacy of the FS program, which ignores the time cost in food at home production.     

Competition and the relative productivity of large and small firms

Using a comprehensive dataset on the incidence of price-fixing across British manufacturing industries in the 1950s, I compare collusive and competitive industries and find evidence of a negative relationship between collusion and the labour productivity of larger firms relative to smaller firms. In particular, collusion is associated with a reduction or even a reversal of the productivity gap between larger and smaller firms. This result is robust to controlling for the potential endogeneity of collusion.     

Construction of an economic index to measure the causes of economic insecurity

This paper is an updated study on the causes of economic insecurity in the United States. The authors have constructed an aggregate composite index that measures objectively the major causes of economic insecurity (CEI) in the United States. The CEI index consists of 11 variables that can cause economic insecurity. The time period under investigation is 1960 through 2001. A rising CEI index indicates that the causes of economic insecurity in the United States have increased in relative importance, which results in an increase in economic insecurity. Conversely, a falling CEI index indicates that the causes of economic insecurity have declined in relative importance, which results in a reduction of economic insecurity. However, despite substantial economic growth in the American economy from 1960 through 2001, the CEI index overall showed little improvement. The major conclusion is that the CEI index was 9 percent higher in 2001 than it was in 1960. This result was due largely to the increase in divorce, violent crime, rising out-of-pocket expenditures for health care, inflation, and unemployment. The results for subperiods are dramatically different, and we think more interesting, than the overall results. During the 1960s, there was a small decline in the CEI index. The 1970s showed a dramatic increase in the CEI index, which reflected both high unemployment rates and inflation rates during this period. The 1980s experienced fluctuating levels in the index but little overall change, and the 1990s experienced a sharp decline in the CEI index due largely to a robust economy. The CEI index has increased more recently, which reflects largely the recent 2001 business recession. The correlation coefficient of the CEI index with the University of Michigan's well-known Index of Consumer Sentiment is ?676. This figure shows that as the CEI index rises, consumer sentiment about the American economy becomes pessimistic and negative.     

Revisiting and extending our understanding of Pierre Wack's the gentle art of re-perceiving

Pierre Wack's 1985 Harvard Business Review papers are two of the most frequently referenced in the scenario planning literature. Wack argued that planning had to be based on the more predictive elements of the business environment. If not, plans would be based on uncertainty and a ‘best guess’ basis. Yet there is a lack of subsequent empirical research to investigate Pierre Wack's contribution. The research findings presented in this paper extend our understanding of Wack's contribution. We show how social discourse during scenario building helped to make sense and reveal the significance of historical events. These historical events were seen, but not previously understood; consequently a new understanding of reality emerged. The findings are in contrast to Wack's explanation of re-perceiving and extend our understanding of the basis of re-perceiving with scenarios.
