The Incidence of Public Spending on Healthcare: Comparative Evidence from Asia

The article compares the incidence of public healthcare across11 Asian countries and provinces, testing the dominance of healthcareconcentration curves against an equal distribution and Lorenzcurves and across countries. The analysis reveals that the distributionof public healthcare is prorich in most developing countries.That distribution is avoidable, but a propoor incidence is easierto realize at higher national incomes. The experiences of Malaysia,Sri Lanka, and Thailand suggest that increasing the incidenceof propoor healthcare requires limiting the use of user fees,or protecting the poor effectively from them, and building awide network of health facilities. Economic growth may not onlyrelax the government budget constraint on propoor policies butalso increase propoor incidence indirectly by raising richerindividuals' demand for private sector alternatives.     

Adjustment of inputs and measurement of technical efficiency: A dynamic panel data analysis of the Egyptian manufacturing sectors

The purpose of this article is to construct a dynamic stochastic production frontier incorporating the sluggish adjustment of inputs, to measure the speed of adjustment of output, and to compare the technical efficiency estimates from this dynamic model to those from a static model. By assuming instantaneous adjustment of all inputs, a static model may underestimate technical efficiency of a production unit in the short-run. However, in this article I show that under the assumption of similar adjustment speed for all inputs, a linear partial adjustment scheme for output characterizes the dynamic production frontier. The dynamic frontier with time-invariant technical efficiency is estimated using the system GMM (generalized method of moments) estimator. Applying the model and estimation method on a panel data set spanning 9?years of data on private manufacturing establishments in Egypt, I find that (1) the speed of adjustment of output is significantly lower than unity, (2) the static model underestimates technical efficiency by 4.5 percentage points on average, and (3) the ranking of production units based on their technical efficiency measures changes when the lagged adjustment process of inputs is taken into account.     

The Effect of Internal Control Certification Regulatory Changes on Real and Accrual-based Earnings Management

ABSTRACT

This study examines the effect of changes in internal control certification requirements (ICCR) on the earnings management choices of Australian firms in the period 2007–2015. The Australian setting is unique as the certification requirements change from voluntary in 2004–2007 to mandatory in 2008–2014, before being abolished in 2015. Consistent with the notion that real earnings management (REM) is less susceptible to detection, the results suggest that firms place greater reliance on REM than on accrual-based earnings management (ABEM) when having to comply with certification requirements. In particular, I find voluntary certifiers have lower REM and ABEM relative to first-time certifiers in the mandatory period between 2008 and 2014, and there is an increase in REM activities among first-time mandatory period certifiers. Moreover, firms that discontinue certification, after the abolition of the requirement in 2015, switch from REM to ABEM. This suggests that regulatory ICCR changes affect firms’ earnings management choices.     

On Corporate Virtue

This paper considers the question of virtues appropriate to a corporate actor’s moral character. A model of corporate appetites is developed by analogy with animal appetites; and the pursuit of initially virtuous corporate tendencies to an extreme degree is shown to be morally perilous. The author thus refutes a previous argument which suggested that (1) corporate virtues, unlike human virtues, need not be located on an Aristotelian mean between opposite undesirable extremes because (2) corporations do not have appetites; and (3) corporate virtues must serve the end of sustainable profit. If these disanalogies between corporate and human virtue no longer hold, then the stage is set for us to formulate a more adequate model of good corporate character that would encompass other-regarding virtues.     

Descending price multi-item auctions

We propose a simultaneous descending price auction mechanism to sell multiple heterogeneous items, each owned by a distinct seller, to a number of buyers. Each buyer has known private valuations on items, and wants at most one item. We show that if the sellers follow a descending price offer procedure and the buyers follow a greedy strategy for accepting the offers, the auction results in a nearly efficient allocation, and terminates close to a competitive equilibrium price vector. The descending price offer strategy of the sellers is close to a Nash equilibrium. However, we show that the buyers are better off waiting in our auction. There is a maximum limit (corresponding to the minimum competitive equilibrium price vector) till which they can wait without running into the risk of not winning any item. If the buyers wait within this limit, the prices can be brought arbitrarily close to a uniquely defined competitive equilibrium price vector.     

Special issue: Australian Accounting Standards Board Research Forum

The Australian Accounting Standards Board (AASB) engages with academics and encourages them to make practical recommendations for the standard‐setter across three sectors: for‐profit, public and other not‐for‐profit sectors. In doing so, the AASB organised Research Forums in 2016 and 2017 that were of great value to researchers, practitioners and the standard‐setters. Four papers from the Forums in 2016 and 2017 were submitted and accepted for publication in this special issue. This paper provides an overview of the Forum, discusses the impact of conducting research and how the findings of the researchers informed the AASB’s standard‐setting process.     

Economic impact of hypoglycemia among insulin-treated patients with diabetes

Objective: The objective of this study was to assess the cost of hypoglycemic events among insulin-treated patients with diabetes and the potential cost savings to a hypothetical US health plan and employer of reducing hypoglycemic events with a device intervention.

Methods: A cost-calculator model was developed to estimate the direct costs of hypoglycemic events, accounting for diabetes type, age, and event severity. Model inputs were derived from published incidence rates of hypoglycemic events and direct medical costs. Assumed intervention efficacy was based on published studies of an emerging technology which yielded 72.2% (LGS Trial; ACTRN12610000024044) and 31.8% (ASPIRE Trial; NCT01497938) reductions in severe and non-severe hypoglycemic events, respectively. Model outcomes—including the number of severe (requiring medical assistance) and non-severe events, and direct/indirect medical costs (excluding intervention costs)—were evaluated over a 1-year period for a hypothetical health plan and employer perspectives.

Results: In a health plan with 10 million enrollees, patients without the intervention would have experienced 0.09 and 14.60 severe and non-severe hypoglycemic events per patient per year (PPPY), respectively (vs 0.02 severe and 9.96 non-severe events with the intervention). This translated into total direct medical cost savings of $45 million ($177 PPPY) for the health plan. For an employer with 100,000 employees, the intervention would have yielded additional savings of $492 PPPY in indirect costs.

Conclusion: Insulin-treated patients experience hypoglycemic events, which are associated with substantial direct and indirect medical costs. The cost savings of reducing hypoglycemic events need to be weighed against the costs of using diabetes device interventions.
