Naturalised epistemology and economics

The relevance to economics of naturalised epistemology (alsoknown as the naturalistic turn) from philosophy of science hasrecently been argued by economic methodologists, especiallyby D. Wade Hands (Reflection Without Rules: Economic Methodologyand Contemporary Science Theory, Cambridge, Cambridge UniversityPress, 2001). This concept is held by Hands to constitute partof the ‘new economic methodology’ that consistsof the ‘interpenetration of economics and science theory’.Contrary to Hands's case, naturalised epistemology is shownhere not to represent a qualitatively new concept, to possesslittle coherent meaning, and to be incapable of charting aninnovative way forward for economics. Although there are moreissues concerning naturalism bearing on economics than are notedby Hands, three specific limitations of naturalised epistemologyare discussed. These and other limitations are related to theeconomics examples Hands proposes suggesting the usefulnessof naturalised epistemology for economics.     

Earnings management,audit adjustments,and the financing of corporate acquisitions: Evidence from China

Acquirers are motivated to overstate earnings prior to stock-financed acquisitions. We hypothesize that audits help to detect and correct such overstatements. We test this using a difference-in-differences design, which compares audit adjustments to earnings for stock-financed and cash-financed acquirers before versus after the acquisitions. Consistent with our hypothesis, we find larger downward adjustments in the audits immediately before stock-financed acquisitions. Further analysis of regulatory sanctions suggests the downward adjustments are in fact warranted, rather than auditors being overly conservative. Moreover, modifications in audit reports suggest that downward adjustments do not correct all of the reporting irregularities in audited financial statements.     

Spurious regressions with stationary series

A spurious regression occurs when a pair of independent series, but with strong temporal properties, are found apparently to be related according to standard inference in an OLS regression. Although this is well known to occur with pairs of independent unit root processes, this paper finds evidence that similar results are found with positively autocorrelated autoregressive series or long moving averages. This occurs regardless of the sample size and for various distributions of the error terms.     

Income Shifting and International Transfer Pricing: A Three-Country Example

There is a long held belief that international transfer pricing (ITP) is used by multinational enterprises (MNEs) to minimize global tax liability. On the one hand, this is a rational economic response to market imperfections created by national governments. An alternative view decries such actions as anti-competitive and an abuse of power. This article ex-amines the potential benefit to enterprises of ITP manipulation when a real world combination of fiscal rules are simultaneously applied in practice. The countervailing impact of different national rules appears to result in ITP having a minor significance on parent after-tax income. Differential rates cause minor benefits but the absence of a form of tax, such as withholding tax, can provide substantial opportunities to maximize global after-tax income through the choice of transfer price. ITP can therefore provide benefits when national jurisdictions do not have consistent forms of taxation. In all the scenarios explored, major variations are apparent in the after-tax income of subsidiaries operating under different combinations of fiscal regimes and ITP policies. The tension between head-quarter and subsidiary management may be most pronounced when a subsidiary is located in a jurisdiction not having a complete range of tax forms.     

A long memory property of stock market returns and a new model

A ‘long memory’ property of stock market returns is investigated in this paper. It is found that not only there is substantially more correlation between absolute returns than returns themselves, but the power transformation of the absolute return ¦r_t¦^d also has quite high autocorrelation for long lags. It is possible to characterize ¦r_t¦^d to be ‘long memory’ and this property is strongest when d is around 1. This result appears to argue against ARCH type specifications based upon squared returns. But our Monte-Carlo study shows that both ARCH type models based on squared returns and those based on absolute return can produce this property. A new general class of models is proposed which allows the power δ of the heteroskedasticity equation to be estimated from the data.     

Employee Movements from Audit Firms to Audit Clients

Regulators have expressed concerns about the “revolving door” between auditors and clients, whereby audit employees move directly from audit firms to audit clients (i.e., “direct alumni hires”). Regulators are concerned that these direct hires could compromise audit quality, partly because these employees could have previously audited their hiring company's financial statements. In contrast, we examine accounting and finance executives who move indirectly from audit firms to audit clients and who could not have previously audited the hiring company's financial statements (i.e., “indirect alumni hires”). We show that indirect hires occur more often than the direct hires that have concerned regulators. We predict and find that both direct and indirect alumni hires are associated with lower rates of executive turnover and audit firm turnover. However, there is no evidence that the reduced rates of executive turnover are explained by managerial entrenchment or that these hires are associated with lower audit quality. Overall, our findings suggest that direct and indirect employee movements from audit firms to audit clients are beneficial to executives, audit clients, and audit firms because they reduce the incidence of costly turnover.     

Housing booms and media coverage

This article analyses news media coverage of the housing market. Building on theories of media influence where word of mouth is the final mechanism of opinion change but media initiate discourse, I examine the relationship between news media and the recent UK house price boom. Over 30 000 articles on the UK housing market from the period 1993 to 2008 are analysed, and it is found that media Granger-caused real house price changes, suggesting the media may have influenced opinions on the housing market. However, media sentiment on the housing market did not change with the secular increase in house prices in the 2000s, suggesting that the media did not contribute to the UK’s housing boom and may have helped constrain it.     

Size and book to market effects and the Fama French three factor asset pricing model: evidence from the Australian stockmarket

The present study adds to the sparse published Australian literature on the size effect, the book to market (BM) effect and the ability of the Fama French three factor model to account for these effects and to improve on the asset pricing ability of the Capital Asset Pricing Model (CAPM). The present study extends the 1981–1991 period examined by Halliwell, Heaney and Sawicki (1999) a further 10 years to 2000 and addresses several limitations and findings of that research. In contrast to Halliwell, Heaney and Sawicki the current study finds the three factor model provides significantly improved explanatory power over the CAPM, and evidence that the BM factor plays a role in asset pricing.
