The Optimal Provision of Curative Goods

We analyze the optimal contract between a risk neutral regulator providing a curative goods and a risk averse patient who learns the realized value of his/her health status after the contracting stage. Consumption of a curative good (healthcare) reduces the disutility associated with a disease. We show that the consumption of curative goods is larger than in the complete information case, that this overprovision increases with the degree of patients’ risk‐aversion and the marginal cost of treatment. Ceilings on the amount of healthcare are part of the optimal contract when risk aversion is important.     

A Critical Review of the Literature on Nutritional Labeling

A comprehensive overview and critique of the nutrition labeling literature is provided. Studies examining the design and features of label formats and their impact on consumers being better informed and engaging in healthier behaviors are examined to summarize available knowledge in the field. The review suggests that while the extant literature has provided worthwhile critiques of the Nutrition Labeling and Education Act in terms of meeting its stated goals, as well as other general insights, it allows only for very tentative and conditional statements about factors related to the “bottom line” effectiveness of nutritional labeling. The outcome of the review suggests that a more holistic view of nutritional labeling is needed. Suggestions for future research that focus on both conceptualizations of the studies as well as methodology are made.     

Benchmark Management During Australia's Transition to International Accounting Standards

Practitioners and commentators have raised concerns that Australian companies exploited opportunities to benchmark manage during the transition to international financial reporting standards (IFRS). However, as yet, no paper has explored this possibility. This study analyses the reconciliations of AGAAP into AIFRS for 457 companies listed on the ASX 500. Results show that 16.85% of companies provided erroneous information of a material nature in their reconciliations and that, on the balance of probabilities, 5.03% of companies in the sample managed their prior year's earnings benchmarks. This has implications for countries considering whether to adopt IFRS and countries which have already established timetables for their transitions.     

Designing Multi-unit Multiple Bid Auctions: An Agent-based Computational Model of Uniform, Discriminatory and Generalised Vickrey Auctions

Multi-unit auctions are being used by public agencies to allocate resources and to purchase services. These auctions resolve the lumpy bid problem inherent in single-bid auctions by allowing bidders to submit a supply or demand schedule. However, the choice of pricing formats for multi-unit auctions is controversial. Neither economic theory nor laboratory experiments depict a complete picture of how alternative pricing formats perform in terms of budgetary or allocative efficiency. This paper constructs an agent-based computational model to compare uniform, discriminatory and generalised Vickrey pricing formats under different degrees of competition and heterogeneity in the bidder population.     

Market Games in Successive Oligopolies

This paper introduces a new approach to successive oligopolies. We draw on market games à la Shapley–Shubik to examine how successive oligopolies operate between downstream and upstream markets when the input price is determined by the action of all firms, downstream and upstream both. This approach differs from the classical one as it allows us to consider downstream firms that exercise market power both in both downstream and upstream markets. We perform a comparison of the market outcome with each scenarios as well as a welfare analysis.     

Volatility Information Trading in the Option Market

This paper investigates informed trading on stock volatility in the option market. We construct non-market maker net demand for volatility from the trading volume of individual equity options and find that this demand is informative about the future realized volatility of underlying stocks. We also find that the impact of volatility demand on option prices is positive. More importantly, the price impact increases by 40% as informational asymmetry about stock volatility intensifies in the days leading up to earnings announcements and diminishes to its normal level soon after the volatility uncertainty is resolved.
