Effects of Progressive Taxes under Decentralized Bargaining and Heterogeneous Labor

We consider changes in income tax progressivity in an economy where workers' productivities differ and workers and firms bargain individually over wages. With given employment a pure increase in tax progressivity reduces wages by reducing workers' relative bargaining power. When average taxes also increase, after-tax wages are unambiguously reduced, while the effects on gross wages and firm profitability are ambiguous. We next endogenize employment and firm entry under a uniform worker productivity distribution and the government's only policy instrument is a linear income tax. While a first-best solution then is ruled out, a second-best solution can be implemented using a family of linear tax functions, where a more progressive tax implies a higher tax revenue to the government. We show that the government can increase its tax revenue, and reduce after-tax income differences, without any additional disturbance to allocation.     

A NOTE ON TAXATION AND THE LEASING DISCOUNT RATES

It is demonstrated that the discount rate for taxes in the traditional formula for the after-tax cost of debt is misspecified for the UK situation. Several new formulae are derived for the after-tax costs for specific periods, including the accounting period and the tax lag. Iterative solution methods are not required.     

The impact of a partial borrowing limit on financial decisions

We consider a consumption, investment, life insurance, and retirement decision problem in which an economic agent is allowed to borrow against only a part of future income. The closed-form solution is attained by applying a dual approach that directly imposes the conditions for the borrowing limit on a dual value function. We provide analytic comparative statics for optimal strategies with rigorous proofs. It is confirmed that a more stringent borrowing limit leads to less consumption and less life insurance purchase. However, even with a tighter borrowing limit, an agent with weak incentive to retire can invest more when the wealth level is high enough. We also show that a more stringent borrowing limit can delay or hasten the optimal retirement timing depending on the agent's current wealth level.     

TWO DCF APPROACHES FOR VALUING COMPANIES UNDER ALTERNATIVE FINANCING STRATEGIES (AND HOW TO CHOOSE BETWEEN THEM)

This is the sequel to the authors' 1989 article discussing the two basic discounted cash flow approaches for valuing debt-financed transactions and corporations: weighted average cost of capital (WACC) and adjusted present value (APV). The WACC method discounts all after-tax (but pre-interest) cash flows at the company's weighted average cost of capital. The APV method treats the value of a levered firm as the value of the same firm if financed entirely with equity plus the discounted value of the interest tax shields from the debt its assets will support. The authors argue that the WACC approach is more practical if the firm intends to hold its (market) leverage ratio relatively constant over time, but that the APV technique is the preferred method if the firm plans to reduce its leverage ratio according to a pre-determined schedule (as tends to be the case in highly leveraged transactions).     

Taming animal spirits: risk management with behavioural factors

In several countries a major factor contributing to the current economic crisis was massive borrowing to fund investment projects on the basis of, in retrospect, grossly optimistic valuations. The purpose of this paper is to initiate an approach to project valuation and risk management in which ‘behavioural’ factors—Keynes’ ‘animal spirits’ or Greenspan’s ‘irrational exuberance’—can be explicitly included. An appropriate framework is risk-neutral valuation based on the use of the numéraire portfolio—the ‘benchmark’ approach advocated by Platen and Heath (A benchmark approach to quantitative finance. Springer, Berlin, 2006). In the paper, we start by discussing the ingredients of the problem: ‘animal spirits’, financial instability, market-consistent valuation, the numéraire portfolio and structural models of credit risk. We then study a project finance problem in which a bank lends money to an entrepreneur, collateralized by the value of the latter’s investment project. This contains all the components of our approach in a simple setting and illustrates what steps are required. In a final section, we briefly discuss the econometric problems that need to be solved next.     

Numerical methods for dynamic Bertrand oligopoly and American options under regime switching

Bertrand oligopolies are competitive markets in which a small number of firms producing similar goods use price as their strategic variable. In particular, each firm wants to determine the optimal price that maximizes its expected discounted lifetime profit. The oligopoly problem can be modeled as nonzero-sum games which can be formulated as systems of Hamilton–Jacobi–Bellman (HJB) partial differential equations (PDEs). In this paper, we propose fully implicit, positive coefficient finite difference schemes that converge to the viscosity solution for the HJB PDE from dynamic Bertrand monopoly and the two-dimensional HJB system from dynamic Bertrand duopoly. Furthermore, we develop fast multigrid methods for solving these systems of discrete nonlinear HJB PDEs. The new multigrid methods are general and can be applied to other systems of HJB and HJB-Isaacs PDEs arising from American options under regime switching and American options with unequal lending/borrowing rates and stock borrowing fees under regime switching, respectively. We provide a theoretical analysis for the smoother, restriction and interpolation operators of the multigrid methods. Finally, we demonstrate the effectiveness of our method by numerical examples from the dynamic Bertrand problem and pricing American options under regime switching.     

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.     

The impact of mutual fund distributions on after-tax returns

This paper analyzes the impact of mutual fund distributions on after-tax returns. Mutual fund objective and management style are the two most important factors which determine the proportion of the fund's total return that is paid out in distributions. The larger the fund's annual distributions, the greater the amount of return lost to taxes. The correlation between portfolio turnover and after-tax return is examined and found to be low. A measure of effective portfolio turnover is developed to show the real effect of turnover on distributions. Within some mutual fund categories, the investor can increase after-tax returns by one or two percent by selecting funds with low distributions.     

Discounting and the Treatment of Taxes in Impairment Reviews

Abstract:  IAS 36 requires an asset's recoverable amount to be measured by discounting its pre-tax rather than post-tax cash flows. Although defined so as to produce the same value, the pre-tax approach is claimed to be simpler and more reliable. The paper demonstrates that an appropriate pre-tax discount rate varies between assets with different tax depreciation schedules and that it changes over time. Hence, pre-tax discounting is likely to become complex. The paper advocates an amendment of the standard such that value in use is measured by company-specific after-tax cash flows, and such that deferred taxes are included in the impairment review.     

Global Liquidity,House Prices,and the Macroeconomy: Evidence from Advanced and Emerging Economies

In this paper, we first compare house price cycles in advanced and emerging economies using a new quarterly house price data set covering the period 1990–2012. We find that house prices in emerging economies grow faster, are more volatile, less persistent, and less synchronized across countries than in advanced economies (AEs). We also find that they correlate with capital flows more closely than in AEs. We then condition the analysis on an exogenous change to a particular component of capital flows: global liquidity, broadly understood as a proxy for the international supply of credit. We identify this shock by aggregating bank‐to‐bank cross‐border credit and by using the external instrumental variable approach introduced by Stock and Watson (2012) and Mertens and Ravn (2013). We find that in emerging markets (EMs) a global liquidity shock has a much stronger impact on house prices and consumption than in AEs. We finally show that holding house prices constant in response to this shock tends to dampen its effects on consumption in both AEs and EMs, but possibly through different channels: in AEs by boosting the value of housing collateral and hence supporting domestic borrowing; in EMs, by appreciating the exchange rate and hence supporting the international borrowing capacity of the economy.     

Modigliani and Miller Again Revisited: The Cost of Capital with Unequal Borrowing and Lending Rates

The financial literature asserts that financial managers must borrow at least to some degree if they are to optimise the value of their companies. This result has been described in the literature as ‘perhaps the single most important result in the theory of corporate finance obtained in the last 30 years’ (Copeland and Weston, 1988, p. 443). Based on US tax systems, the value added to a company by debt has been estimated as high as 35 to 50% of the debt's market value. More recently in this journal, Ashton (1989b) has argued that under the present UK tax system, the theoretical tax advantage afforded by debt should be estimated at no more than 13% of the debt's market value. The contribution of this paper is to draw attention to an aspect of borrowing that has largely escaped attention, but which nevertheless affects the above conclusions: namely, that the market spread between borrowing and lending constitutes a ‘cost’ for corporate borrowing. This paper demonstrates that in the context of the present UK tax system, this ‘cost’ of borrowing is sufficient to nullify entirely the formerly perceived financial tax benefits of corporate borrowing. We conclude that, at present, corporate borrowing could imply a net disadvantage for the valuation of a company's equity by about 6 or 7% of the debt's market value.     

The Federal Home Loan Bank system: Cause or cure for disintermediation?

The Federal Home Loan Bank (FHLB) system issues bonds in order to obtain funds for savings and loan associations during periods of disintermediation. A question has arisen as to whether the FHLB actually causes additional disintermediation by its bond issues. Although this concern has been examined before statistically, with a connection found between FHLB borrowing and disintermediation, no explicit attention has been devoted to the possibility that such a statistical relationship may reflect a causality relationship in which disintermediation is the cause and FHLB borrowing the effect rather than the reverse. This study utilizes a simultaneous equation model and estimator to examine such two-way causality and finds it exists but that substantial disintermediation is caused by FHLB borrowing even after correcting for simultaneous equation bias.     

The association of departures from spending rate equilibrium to municipal borrowing cost

The U.S. municipal bond market has grown dramatically in recent decades. Debt financing has become a more important source of capital for municipalities, yet research into the association of fiscal management and borrowing cost has not been directly addressed since before GASB's formation in 1984. We attempt to fill this void and contribute to the dialog concerning municipal managerial competence and its association with borrowing cost by studying a sample of 3285 county general obligation bonds over a 13-year period. We resolve conflicting and counterintuitive results in prior work and demonstrate that the lowest borrowing cost is achieved where general fund revenues equal general fund expenditures (i.e., equilibrium spending rate). Further, we find that the association between spending rate and borrowing cost is nonmonotonic, nonlinear, and asymmetric. We demonstrate that maintenance of a spending rate equilibrium point may be a way of achieving minimum borrowing cost. In the context of fiscal constraints and the increased reliance on credit markets by municipalities, managing to the spending rate equilibrium may reduce the borrowing costs of providing municipal services.     

Firm age and the evolution of borrowing costs: Evidence from Japanese small firms

This paper investigates how firms’ borrowing costs evolve as they age. Using a new panel data set of about 100,000 bank-dependent small firms for 1997–2002 and focusing on the channel of “adaptation” (i.e., surviving firms’ borrowing costs decline as they age) and that of “selection” (i.e., total borrowing costs decline as defaulting firms exit), we find that the reputation hypothesis suggested by Diamond (1989) provides a more plausible explanation of the downward sloping age profile of borrowing costs than the firm dynamics (Cooley and Quadrini, 2001) or the relationship banking (Boot and Thakor, 1994) hypothesis. In addition, we examine whether the firm selection process in Japan has been natural or unnatural. Our findings suggest that it has been natural in that firms with lower quality are separated, face higher borrowing costs, and are eventually forced to exit, which contrasts with the results of previous studies on credit allocations in Japan, including Peek and Rosengren (2005). Further, we find that the evolution of borrowing costs is partially due to selection but is mainly attributable to adaptation.     

Personal taxes and the time variation of stock returns – evidence from the UK

A potential explanation for the time-series predictability of market returns with dividend yields is the differential tax treatment of capital gains and dividends. This article investigates to what extent the predictability of long-horizon returns can be explained by this tax effect. Assuming that after-tax expected returns are constant, we test the derived relationships between pretax returns and lagged dividend yields with UK data. We also compare the predictability of before-tax long-horizon returns with that of after-tax returns. The results indicate that the tax treatment of dividends does not significantly contribute towards the predictability of stock returns.     

INCORPORATION OF TAX CONSIDERATIONS INTO THE COMPUTATION OF DURATION

In this paper, the immunization process is extended to protect after-tax income, and the duration indices for after-tax immunization are derived. Selection of the appropriate index depends on individual investor differences in tax regulations. Attention is focused on the mutually exclusive decisions to amortize or not to amortize premia or discounts.     

Income repatriation decision for multinational corporations: Tax issues

This paper analyzes the existing asymmetry in the US corporate tax law governing the determination of foreign tax credits earned by US firms with foreign subsidiaries. The existing asymmetry results in the US government de facto holding foreign currency put options against US firms with foreign subsidiaries. Combined with the exchange rate volatility, this tax law asymmetry reduces the effective foreign after-tax rate of return and, thus, makes it profitable for US firms to repatriate their foreign source income earlier even when the foreign after-tax rate of return is higher than the domestic rate. Although this paper identifies this asymmetry in the tax law and analyzes its potential effect on the timing of foreign source income repatriation, it is an open question as to the economic significance of this tax code feature provided the firms’ ability to curry the unused tax credit forward for up to 10 years.     

The influence of international status and operating segments on firms’ choice of bonus plans

This paper investigates why firms select different accounting measures of performance when determining executive bonus compensation. Specifically, we investigate whether firms with a greater multinational presence and with more operating segments are more likely to use after-tax bonus plans. Newman (1989) investigated the relation between multinational status and bonus plan choice for the mid-1970s and did not find strong results. However, given the increased global implications of business decisions over the last two decades, it should be beneficial to investigate this issue for a more recent time period. We obtained financial information from 266 firms, 70 with after-tax compensation plans, 186 with before-tax compensation plans, and 10 with hybrid compensation plans. Logistic regression analysis suggests that large firms reporting a large number of operating segments and having a high level of multinational operations are more likely to select after-tax rather than before-tax compensation plans.     

Scope of Auditors' Liability,Audit Quality,and Capital Investment

One of the fundamental issues in the discussion of auditors' liability is to whom auditors should be held liable for ordinary negligence under common law. Three judicial viewpoints prevail: the restrictive privity approach, the more liberal Restatement approach, and the most liberal foreseeability approach. To compare these three approaches from an efficiency perspective, this paper develops a model that features an owner-managed firm, an independent auditor, a continuum of unrelated lenders, and an impartial court. Double effort-incentive problems appear for the firm and the auditor. The firm has an additional incentive problem due to the sequential nature of its borrowing. This paper shows that the effort-incentive problem and the sequential borrowing problem of the firm render unambiguous improvements in audit effort/quality, capital investment, and social welfare as the judicial approach governing the scope of auditors' liability becomes more conservative.
