The Marginal Cost of Australian Income Taxation*

When the financing of expenditure programmes involves a welfare cost, that cost should be considered part of the opportunity cost of the expenditure programme. In this paper, we explore some concepts of the welfare loss of taxing labour income. We correct some measures previously applied and estimate the marginal cost of Australian public funds. Using our measure of the cost of public funds, we explore the costs of policy options in the motor vehicle industry.     

THE ADOPTION OF STATE ELECTRICITY REGULATION: THE ROLE OF INTEREST GROUPS*

This paper examines the adoption of state electricity regulation around the beginning of the 20th century. I model this decision as a hazard rate to determine what influenced the adoption of state regulation. I find that adoption is positively correlated with capacity shortages, greater wealth and lower residential electricity penetration rates. These results suggest that state regulation responded to regulatory inefficiencies and residential consumer interests. In addition, adoption rates were higher in states that had a strong industrial and coal mining presence. These results are consistent with the interest group and contracting theories of regulation.     

Delayed Expected Loss Recognition and the Risk Profile of Banks

This paper investigates the extent to which delayed expected loan loss recognition (DELR) is associated with greater vulnerability of banks to three distinct dimensions of risk: (1) stock market liquidity risk, (2) downside tail risk of individual banks, and (3) codependence of downside tail risk among banks. We hypothesize that DELR increases vulnerability to downside risk by creating expected loss overhangs that threaten future capital adequacy and by degrading bank transparency, which increases financing frictions and opportunities for risk‐shifting. We find that DELR is associated with higher correlations between bank‐level illiquidity and both aggregate banking sector illiquidity and market returns (i.e., higher liquidity risks) during recessions, suggesting that high DELR banks as a group may simultaneously face elevated financing frictions and enhanced opportunities for risk‐shifting behavior in crisis periods. With respect to downside risk, we find that during recessions DELR is associated with significantly higher risk of individual banks suffering severe drops in their equity values, where this association is magnified for banks with low capital levels. Consistent with increased systemic risk, we find that DELR is associated with significantly higher codependence between downside risk of individual banks and downside risk of the banking sector. We theorize that downside risk vulnerability at the individual bank level can translate into systemic risk by virtue of DELR creating a common source of risk vulnerability across high DELR banks simultaneously, which leads to risk codependence among banks and systemic effects from banks acting as part of a herd.     

PERSISTENCE OF TECHNOLOGICAL LEADERSHIP: EMERGING TECHNOLOGIES AND INCREMENTAL INNOVATION*

In a model of competitive innovation, I derive theoretical conditions for an entrant to displace the incumbent firm by innovating in an undeveloped, substitute (emerging) technology. The main result presents conditions on profitability and innovation speed that yield a Markov Perfect Equilibrium in which the entrant pursues the emerging technology, while the incumbent chooses to persist with the established technology and collect short‐run profits. Notably, this result does not require the entrant's superiority to the incumbent for innovation. Finally, when the model is calibrated to hard drive industry data, its predictions are consistent with the observed outcomes.     

Closing the Loop: Review Process Factors Affecting Audit Staff Follow‐Through

The PCAOB recently expressed concern regarding the sufficiency and effectiveness of review and supervision of audit fieldwork. For the audit review process to succeed as a quality control mechanism, any issues or questions identified by a reviewer must be adequately resolved and documented in the workpapers. If audit review fails to correct for errors/biases in the work of reviewees, there can be serious detrimental effects on audit quality and, in turn, financial statement quality. Our study extends the literature by examining the phase of the review process in which reviewees respond to (or “close”) notes/comments provided by their reviewers. Utilizing an experiment, we find that certain contextual factors (review timeliness and review note frame) influence reviewee follow‐through during this critical phase. Specifically, we find that a delayed review elicits significantly lower effort levels than a timely review. Review note frame (i.e., how the reviewer phrases the rationale given for the underlying directive of a review note) significantly affects reviewee effort and performance when the review is timely. Through mediation analyses, we explore the mediating effect of effort on performance. In addition, we find that reviewer delay leads to greater over‐documentation.     

Optimal Taxation of International Income Flows*

Double taxation of international income flows has been regarded as undesirable and international tax agreements have been negotiated to avoid it. The questions asked are whether double taxation is appropriate and whether cooperation is required to reach the optimal solution. The results are that generally some double taxation is desirable, as long as taxes are applied at the appropriate rates, and that an efficient solution can be attained in the absence of explicit cooperation using a deduction rule, instead of the now commonly used credit rule. A rationale for the current system of tax agreements and their emphasis of the credit rule is discussed.     

THE INDUSTRIAL ORGANIZATION OF THE CHINESE FOOD ECONOMY: SOCIALISTIC OR CAPITALISTIC?

The controversy over the transformation of socialism recently has focused on China. The analysis here uses an industrial ORGANIZATION framework to portray the key features of "Socialism with Chinese Characteristics." The structures of ownership, supply, and demand and the process of price formation are analyzed to explicate the ramifications of the reform process and the changing patterns of government intervention and market forces in the Chinese food economy. An examination of this. fusion reveals a number of implications for international socialism.
