  • Virtual Intermediaries: Consumption Tax Problems in Japan, Europe, and the United States –The Case of the Virtual Travel Agent

    Richard T. Ainsworth, Hiroki Akioka

    Kansai University Review of Economics   No.12, pp25-48   2010.3

     More details

    Based on the structure of the Japanese Consumption Tax (CT) and estimates of losses in similar taxes in other jurisdictions, this paper estimates that approximately \26,532 million has not been collected each year for the past eight to ten years, even though these taxes have been paid by hotel guests to reservation agents when on-line reservations were made with virtual travel agents.This is a comparative assessment.It is focused on the Japanese CT, but it draws solutions from observations of what has been done in Europe’s VAT, and American sales taxes.

  • Electronic Tax Fraud – Are there "Sales Zappers" in Japan?

    Richard T. Ainsworth, Hiroki Akioka

    Kansai University Review of Economics   No.11, pp1-34   2009.3

     More details

    Skimming cash receipts is an old fashioned tax fraud. Modern technology is changing how businesses skim. The agents of change are software applications – Phantom-ware ("hidden," pre-installed programming option(s) in ECRs) and Zappers (add-on programs for POS systems). These programs are a serious problem in Canada, the Netherlands, Germany, Brazil, Australia and Sweden. Why are they not a concern in Japan?Although it may be that they are not used in the Japan, it seems more likely that they are simply not being detected, because of insufficient (or technologically limited) audit resources. The authors hope to focus attention on this issue.

  • A Proposal for the Tax Commission: Biometrics and Certified Software for the Consumption Tax

    Richard T. Ainsworth, Hiroki Akioka

    Kansai University Review of Economics   No. 9, pp73-109   2007.3

     More details

    Significant change is anticipated in the Japanese Consumption Tax.The Japanese Tax Commission is recommending that the rate should double, multiple rates should be employed, and the bookkeeping method of accounting should be abandoned in favor of the European invoice method. The Tax Commission faces a tax policy dilemma.The aging population drives the need for a tax increase (making the Consumption Tax an obvious target for revenue enhancement) at exactly the same time the population is shrinking in overall size, thereby reducing the number of working-consumers who can pay the higher tax.This paper proposes a way out of this dilemma.It proposes the adoption of certified transaction tax software at the point of (final) sale, and the distribution (for voluntary use by the needy) of IDs embedded with (a) digitally recognized biometric identifiers and (b) digital tax exemption certificates.Rates could then rise without excessively burdening the poor, elderly and handicapped.

  • Taxing Services under the EU VAT and Japanese Consumption Tax: A ComparativeAssessment of New EU Place of Taxation Rules for Services and Intangibles

    Richard T. Ainsworth, Hiroki Akioka

    Kansai University Review of Economics   No.8 pp1-42   2006.3

     More details

    Place of taxation rules are the seminal cross-jurisdictional provisions of any consumption tax regime.They determine where among competing jurisdictions a particular service is taxed.It is therefore of considerable importance to Japanese businesses and consumers when the European Union undertakes a wholesale revision of the place of taxation rules for services and intangibles.The OECD has recently observed that a general ”lack of international consistency and coherence” in these rules is erecting global trade barriers (double taxation), and provided opportunities for global tax avoidance.This paper compares current and proposed EU place of taxation rules for services and intangibles with companion rules under the Japanese Consumption Tax.It concludes that the OECD observation is correct, and that the proposals do not alleviate EU-Japan ”inconsistencies.”

  • Sarbanes-Oxley and the Provision of Non-Audit Transaction Tax Services :A Comparative Assessment of US, French, Australian and Japanese Rules

    Richard T. Ainsworth, Hiroki Akioka

    Kansai University Review of Economics   No. 7 pp.1-31   2005.3

     More details

    The Sarbanes-Oxley Act of 2002 is US legislation that mandates wide-ranging reforms in the public company financial reporting process.The central concern is with auditor independence.Similar legislation has been enacted in France, Australia and Japan.This paper pays specific attention to the provision of non-audit transaction tax services by the auditor as an example of the US approach.The US approach is contrasted with that of France, Australia and Japan.France and Japan represent extreme positions.The paper considers whether difference in approach to auditor independence will prompt US regulators to exercise extra-territorial regulatory powers over foreign accounting firms that audit firms listing on US exchanges.

  • Information-Oriented Management and Competition-Findings from a Survey of Japanese Toiletry Industry-

    AKIOKA Hiroki

    Kansai University Review of Economics and Business   25巻1号95頁-124頁   1996.9

     More details

    In recent years, more and more firms have been struggling to gain a competitive edge through the effective use of information systems.This type of business management iscalled ”information-oriented management”.There is nothing particular in itself; it is just an effort to put into practice the need for outperforming competition in terms of the quantity and quality of information.However, the very viewpoint of ”information” is what theoretical models of traditional economics have lacked most.The purposes of this paper were to shed light on the nature of information-oriented management in relation to economic theory drawing on some findings of a survey of firms, and thereby to examine what impact this type of business management would have on market competition and on national economy as a whole.

     More details

    In our previous note (1994), we studied the effectiveness of Varian's non-parametric approach to cost minimization and examined its possibility of the application to empirical studies.However, Varian's ”Weak Axiom of Cost Minimization (WACM)”, which is just the essence of this type of approach, was not referred to in detail in that note because of some quantitative constraints.Therefore, in this note, we mainly studied this axiom.

     More details

    Some ”strict” assumptions (or specifications) are often implicitly applied to our models of empirical studies, like ”We assume...” or ”We suppose...”.But, actually, are they true? Varian (1985) showed that we can test for cost minimization of firms ”almost without any assumptions”.This is what is called a ”Non-parametric Approach”.In this note, we studied the effectiveness of this type of approach and examined the possibility of its application to empirical studies.

     More details

    In our previous paper (1993), we could notverify the downward shift of the average costfunction of the Japan Monopoly Corporation inits privatization, and thought this was becauseit was not a ”full” privatization.In this paper, we studied the effect ofthe ”full” privatization of the ”Okinawa Electric Power Corporation”, estimating itsaverage cost function similarly to our previous papers.Moreover, we examined other effects described in the title of this paper above.

     More details

    Through a simple microeconomic analysis, Vickers and Yarrow (1988) showed that the average (unit) cost of a monopolistic firm should be shifted downwards ”considerably” after privatization, so that the social welfare may be improved by it. In this paper, we studied the effect of the privatization of the ”Japan Monopoly Corporation” in 1985, estimating its average cost function by means of the translog frontier functions and the econometric methods of estimation.

    According to the theory of X-Inefficiency, the productive efficiency of a firm is often influenced by its circumstantial factors, especially by various kinds of ”pressure”.Most of the empirical studies on the U.S. major industries show the significant link between a firm's efficiency and the ”pressure” on it.Namely, a certain ”pressure” shifts the firm's average cost function downwards.The degree of this type of ”pressure” is sometimes represented by the firm's ownership form (public or private).This study intended to show whether this implication was also applicable to the Japanese municipal gas industry by means of the translog frontier functions and the econometric methods of estimation with the actual data that consisted of 738 observations.

  • X-Inefficiency-An Empirical Approach

    Language:Japanese   Publisher:Osaka University  

    ”X-inefficiency” is a concept advocated by H. Leibenstein (1966).According to his theory, neither organization nor people work as efficiently as possible for various reasons, especially for the lack of competitive pressure.He called this type of inefficiency”X-inefficiency”.In this paper, we intended to analyze the relationship between ”X-inefficiency” and the ”competitive pressure” in the Japanese major industries from the empirical point of view.For this purpose, we made use of the transcendental logarithmic (translog) frontier functions developed by Professor D. W. Jorgenson et al. (1973) as our theoretical model, and then, we applied the econometric method of estimation suggested by W. H. Greene (1980) to the model.

  • DIGITAL CONSUMPTION TAX (D-CT)

    Richard T. Ainsworth, Hiroki Akioka

    Kansai University Press  2007.3 

     More details

    Modern technology is dramatically changing the way consumption taxes are collected, but it is also changing the way policymakers assess the operation and impact of these taxes.Whether the design is a standard credit-invoice value added tax (VAT) of European design, or a retail sales tax (RST) of American design, or the credit subtraction VAT without invoices type of consumption tax (CT) of Japanese design, technology is having a profound impact.This book begins and ends with a tax reform.It starts with a proposal to the President's (George W. Bush's) Advisory Panel on Federal Tax Reform, and ends with a proposal for the consideration of Prime Minister Junichiro Koizumi's Tax Commission.Neither tax reform commission appears at the moment to be considering technological solutions, although both are critically interested in consumption taxes. In the U.S. case both of the identified structural barriers to a federal level VAT (federal-state coordination and regressivity) can be answered technologically.In the Japanese case a wholesale transformation of the CT is under consideration; one that would move the Japanese CT to an invoice system with multiple rates and a standard rate of 10 percent or higher.The structural departure that this proposal makes from the traditional Japanese CT need not be taken if technological solutions are applied, although the double digit rate increase seems to be a given for revenue reasons.
