Uban Tolled Roads and the Value of Travel Time Savings*

The recent interest in the privatization of major urban roads has opened up the debate on the tolling of such facilities. Central to the identification of optimal tolls is a knowledge of the amount of money individuals are willing to outlay to save travel time. This paper combines a utility maximization framework with stated response data to determine values of time savings in the presence of varying levels of toll for the full set of urban journey purposes. The empirical results provide a basis for establishing one benchmark for toll setting, in the context of substantial lengths of urban roads. There are no tolled urban roads in any major urban area throughout the world     

What do Australian Annual Reports Say About Future Earnings?

Prospective earnings information in Australian firms' annual reports has been claimed to be of sufficient importance to warrant its statutory requirement, or at least its "active encouragement". With the introduction of AASB 1039 Concise Financial Reports, management discussion and analysis is required in some circumstances, although there is no explicit requirement to provide prospective earnings disclosures. A survey of a sample of ASX-listed firms shows that about 25% include some form of earnings forecast, although most are qualitative, while even a coarse measure of their accuracy suggests they are relatively unreliable. These results give rise to some concern that encouraging the provision of prospective earnings data may not necessarily assist investors.     

Toward Consumer Efficiency: A Model for Improved Buymanship

This paper suggests that changes in the economic, marketing, and social environments call for alternative approaches to the traditional models of buymanship. The authors propose a shopping model that incorporates four main tenets: (1) search is conceived as a continuous process; (2) consumers take advantage of retail price competition at one point in time and over time; (3) an acceptable set of brands and stores is integral to purchase decisions; and (4) low price on an acceptable brand triggers purchase. Implications for consumer buying, research, and consumer education are identified.     

Trade Credit and Informational Asymmetry

Commonly used trade credit terms implicitly define a high interest rate that operates as an efficient screening device where information about buyer default risk is asymmetrically held. By offering trade credit, a seller can identify prospective defaults more quickly than if financial institutions were the sole providers of short-term financing. The information is valuable in cases where the seller has made nonsalvageable investments in buyers since it enables the seller to take actions to protect such investments.     

A Theoretical Analysis of Real Estate Returns

In this paper, we consider two hypotheses for the recent performance of real estate returns. The first is the random event argument that real estate is positively correlated with unanticipated inflation but that structural change in expected returns due to a change in the perceived sensitivity of returns to unanticipated inflation has not taken place. The second is the hedge demand argument that formulates the structural shift hypothesis. The paucity of real estate and other expectations data as well as the general identification problem make it extremely difficult to distinguish between these hypothesis. Our tests consist of estimates of inflation betas for various asset categories overtime as well as estimates of the hedge vector, $S^{-1}C$. Although some support for the hedge argument is found, the results are not strong enough to reject the random event argument and conclude that a decline in the required return on real estate due to a relative increase in inflation beta drove returns during the 1970's.     

FINANCE AND GROWTH: NEW EVIDENCE ON THE ROLE OF INSURANCE

This paper provides new evidence that sheds light on the impact of insurance sector development on output growth, capital accumulation and productivity improvement, using data from 51 countries (developed and developing) during 1981‐2005. The dynamic panel data analysis results demonstrate that insurance sector development affects growth predominantly through productivity improvement in developed countries, while in developing countries it promotes capital accumulation.     

Comparative study of phosphate and non-phosphate detergents

A comparison of three different detergents was made by evaluating their properties of soil removal, soil redeposition and calcium carbonate deposition. The detergents included a phosphate granular detergent, a non-phosphate, carbonate built granular detergent and an unbuilt liquid detergent. The local water conditions were moderately hard and clay type soils were used. Detergency was evaluated on the basis of both visual and instrumental colour changes. In effecting soil removal, clay stained fabrics laundered with the phosphate detergent retained only a small amount of soil, while fabrics laundered with the two non-phosphate detergents showed heavier staining. In preventing soil redeposition, the phosphate detergent produced almost no visible redeposition; the unbuilt and carbonate built detergents ranked correspondingly lower. In assessing calcium carbonate deposition, the phosphate and unbuilt detergents showed little or no change, while the carbonate detergent continued to build up deposits with laundering. In summary, the phosphate detergent ranked highest in overall performance, with correspondingly lesser performance from the unbuilt and carbonate detergents.     

Trends and Cycles in GDP

The recent experience in the UK of substantial growth in GDP following the recession of the early 1980s has led to renewed interest in the measurement and explanation of business cycles. Development of economic as well as econometric theory has improved our ability both to measure the cycle more accurately and to offer a better explanation of its behaviour. In this Briefing Paper we present an analysis of these two developments.
