Valuation Implications of Investment Opportunities and Earnings Permanence

This study investigates the value-relevance of accounting earnings in the presence of investment (growth) opportunities after making two theoretical and methodological research design refinements. First, we test for the incremental effect of growth on firms earnings response coefficients after controlling for the extent of transitory earnings under the assumption that the value-relevance of earnings with respect to growth should be stronger when earnings are more permanent. Second, we perform comprehensive factor analysis using market-based and accounting-based measures to construct a composite proxy for investment opportunities. We find that firms investment opportunities and the relative permanence of current earnings affect the value-relevance of those earnings. Additionally, we find that the interaction between permanent earnings and investment opportunities produces an even stronger price response to earnings.     

Decomposition of Japanese Yen Interest Rate Data Through Local Regression

Seven different Japanese Yen interest rates recorded on a daily basisfor the period from 1986 to 1992 are simultaneously analyzed. Byintroducing a new concept of short term trend, we decomposeeach interest rate series into three components, long termtrend, short term trend and irregular. It is obtained by atwo step lowess smoothing technique. After that, amultivariate autoregressive model (MAR) is fitted to the vectorvalued time series obtained by combining those seven irregularcomponents. The decomposition and MAR model fitting were quitesatisfactory. It enables us to understand well various aspects ofinterest rate series from the trends, the MAR (2) coefficientsand its residuals. The result is compared with the decompositionthrough sabl and the advantages of our procedure will bedemonstrated in relations to other parametric model fitting likeARCH or GARCH. Based on the decomposition we can have betterdaily prediction and more stable long term forecasting.     

Nonparametric prediction for the time-dependent volatility of the security price

In this paper we consider a continuous time model for the security price with the time-dependent volatility. It is shown that the non-normality and non-linear dependency of the short-term return, the major characteristics observed on many financial assets, can be incorporated into our model. In order to evaluate the option price formula on the model we propose a nonparametric predictor for the volatility function without reference to a specific functional form. We examine the so-called continuous record asymptotics and show that the proposed predictor is asymptotically minimax for a wide class of the volatility functions. One of the most important results is that the application of the Black-Scholes method can be justified by plugging the proposed predictor in the standard Black-Scholes formula even if the volatility changes over time.     

The Marginal Cost of Funds and the Shadow Prices of Public Sector Inputs and Outputs

Existing studies on the marginal cost of funds (MCF) do not incorporate the public sector inputs explicitly. Incorporating labor and capital as public sector inputs raises questions concerning the definition and the usage of the MCF, and its relation to public sector shadow prices. This paper finds that the MCF should be defined based on the excess revenue rather than the gross revenue; that general equilibrium effects on individuals' net income and government's inframarginal expenditures should be incorporated; and that the MCF measures an element in the shadow price that is solely attributable to the marginal financing, justifying the role of the MCF in cost-benefit analysis and tax reform.     

Is the ‘Perfect’ Timing Strategy Truly Perfect?

In the presence of transaction cost, the perfect timing strategy which holds stocks in a period with positive excess return and holds cash in a period with negative excess return is not necessarily perfect. Using the optimal growth criterion, this paper derives the truly perfect timing strategy which can achieve the maximum long term growth. It is found that such a perfect timing strategy can achieve a much higher annual return than the perfect timing strategy under reasonable transaction cost. Also, it can achieve a return of over 80% when a review period is as short as a day and when transaction cost is low. Using the truly perfect timing strategy as a benchmark, the likely gains from imperfect timing can be more accurately assessed. For a less frequent review schedule, a market timer needs a very high correct prediction probability in order to be at par with the buy-and-hold strategy. However, the needed correct prediction probability is much less when the review schedule is more frequent. Also, the correct prediction probability needed to be at par with the buy-and-hold strategy increases with the transaction cost.     

Modeling Spatial and Temporal House Price Patterns: A Comparison of Four Models

This research reports results from a competition on modeling spatial and temporal components of house prices. A large, well-documented database was prepared and made available to anyone wishing to join the competition. To prevent data snooping, out-of-sample observations were withheld; they were deposited with one individual who did not enter the competition, but had the responsibility of calculating out-of-sample statistics for results submitted by the others. The competition turned into a cooperative effort, resulting in enhancements to previous methods including: a localized version of Dubins kriging model, a kriging version of Clapps local regression model, and a local application of Cases earlier work on dividing a geographic housing market into districts. The results indicate the importance of nearest neighbor transactions for out-of-sample predictions: spatial trend analysis and census tract variables do not perform nearly as well as neighboring residuals.     

The Effect of Mortgage Price and Default Risk on Mortgage Spreads

Variations over time in mortgage yield spreads should reflect changes in the underlying prepayment option value; moreover, the relationship between mortgage yield spreads and interest rate dynamics should weaken as the value of the borrowers prepayment option declines. We verify this hypothesis through an empirical analysis of residential mortgage yield spread behavior, and we also present evidence that the strength of the relationship between mortgage spreads and interest rate dynamics weakens (strengthens) as the level of default risk increases (decreases). This result is consistent with the competing risks effect between a borrowers option to prepay or default. Our results demonstrate the importance of accounting for mortgage price discount to par as well as default risk when developing time series of mortgage yields.     

Environmental Taxes, International Capital Mobility and Inefficient Tax Systems: Tax Burden vs. Tax Shifting

This paper deals with the so-called double dividend of an environmental tax reform. In a model with only labor and a polluting input as factors of production, we find that society faces a trade-off between internalizing environmental externalities and raising revenues in the least distortionary way. However, if capital enters the production structure, an ecological tax reform may render the tax structure more efficient from a non-environmental point of view, thereby raising not only environmental quality but also private incomes.     

Rational Delays: The Case of Real Estate

Real estate markets, for both commercial real estate and single family homes, typically respond to a large negative demand shock with a period during which the volume of transactions and liquidity of real estate declines. Explanations for these periods have focused on overly optimistic owners, imperfections in real estate markets and/or minimum down payment requirements. These are important characteristics of real estate markets, but they do not provide a satisfying explanation for the long-term declines in the number of transactions and liquidity of real estate that frequently follow negative demand shocks. This paper presents estimates, for a specific real estate market (Los Angeles single family dwellings), of the option-like value of an owners interest in a property. Our estimates imply that when an owner has little or negative equity, the value of waiting to sell is likely to exceed the net carrying cost. Consequently, the option value of a potential sellers interest may eliminate the possibility of an otherwise mutually advantageous transaction.     

Horizontal Inequity and Vertical Redistribution

Inequality of post-tax income among pre-tax equals is evaluated andaggregated to form a global index of horizontal inequity in the income tax.The vertical action of the tax is captured by its inequality effect on averagebetween groups of pre-tax equals. Putting the two together, horizontalinequity measures loss of vertical performance. The identification problem,which has previously been thought insuperable, is addressed by a procedurevalidating the banding of income units into close equals groups. Thehorizontal and vertical effects of a major Spanish income tax reform areevaluated. Lines for future investigation are suggested.     

Environmental Taxes and Pre-Existing Distortions: The Normalization Trap

The double-dividend hypothesisclaims that green taxes will both improve the environment andreduce the distortions of existing taxes. According to the earlierliterature on the double dividend the tax rate for pollutinggoods should be higher than the Pigovian tax which fully internalizesthe marginal social damage from pollution, in order to obtaina second dividend. On the contrary, Bovenberg and de Mooij(1994) argue that environmental taxes typically exacerbate, ratherthan alleviate, pre-existing distortions. The optimal pollutiontax should therefore lie below the Pigovian tax. This paper pointsout that there is no real contradiction between these apparentlyopposing policy recommendations. It will be shown that the differencein the results appears because, implicitly, different definitionsof the second-best optimal pollution tax are chosen.     

Inter-Departmental Cost Allocation and Investment Incentives

This paper endeavors to demonstrate that fixed cost allocation can align investment incentives in a multi-period and multi-division setting. In a decentralized firm, a divisional manager can make an investment that benefits both his own and the operations of a downstream division. The relative budgeted activity (RBA) cost allocation method assigns fixed cost charges according to the ratio of a divisions budgeted activity in proportion to that of the firm, and thereby resolves the hold-up problem created by the decentralized setting. Internal accounting rules can be designed to give managers strong incentives to internalize the firms objective regarding efficient investment levels, and alleviate the tension between ex ante investment efficiency and ex post production efficiency. This paper examines how much the fixed charges should be in order to achieve the optimal level of investment.     

Rationing in IPOs

We provide a model of bookbuilding in IPOs, in which the issuer can choose to ration shares. Before informed investors submit their bids, they know that, in the aggregate, winning bidders will receive only a fraction of their demand. We demonstrate that this mitigates the winners curse, that is, the incentive of bidders to shade their bids. It leads to more aggressive bidding, to the extent that rationing can be revenue-enhancing. In a parametric example, we characterize bid and revenue functions, and the optimal degree of rationing. We show that, when investors information is diffuse, maximal rationing is optimal. Conversely, when their information is concentrated, the seller should not ration shares. We provide testable predictions on bid dispersion and the degree of rationing. Our model reconciles the documented anomaly that higher bidders in IPOs do not necessarily receive higher allocations.     

Compensation Design and Career Concerns of Fund Manager

We develop an optimal incentive contract for the fund manager with career concerns. Drawing upon the framework of Gibbons and Murphy (1992), we restructure the performance of fund manager with emphasis on the multiplicative effect of previous effort on the latter period, and derive the positive cross-period linkage of fund managers efforts. In particular, our study derives that a greater first-periods effort by the fund manager will induce more second-period effort and greater compensation in either fixed or variable (performance-related) portion of the payment. Though the total performance related pay might increase as the result of greater effort in the previous period, we show that the pay-performance sensitivity in the second period will decline. Moreover, the initial wealth increase will motivate the fund manager to exert more effort and induce better performance, but decrease the pay-performance sensitivity in the second period.JEL Classification: G2, J33, J41     

Loan Portfolio Swaps and Optimal Lending

Theories on loan portfolio swap hedging are based on a portfolio-choice approach. This paper presents an alternative: a firm-theoretic model for bank behavior with loan portfolio swaps. Our paper derives the optimal loan rate and rate-taking loan amount of the banks portfolio, and relates them to the market loan rate, counterparty loan rate, swap default risk, capital-to-deposits ratio, and deposit insurance. We find that in the bilateral default risk approach, the comparative static results are generated by four factors: the banks risk magnitude about the equity market value, loan composition in the swap contract, the substitution effect in the loan portfolio, and the income effect from the swap transaction. The results imply that changes in the payoff asymmetry in the event of swap default and the banks regulatory parameters have a direct effect on the banks loan portfolio for lending and swap transactions.We would like to thank two anonymous referees for helpful comments and advice.     

Commercial Real Estate Return Performance: A Cross-Country Analysis

This paper investigates the return performance of publicly traded real estate companies. The analysis spans the 1984–1999 time period and includes return data on over 600 companies in 28 countries. The return data reveal a substantial amount of variation in mean real estate returns and standard deviations across countries. Moreover, standard Treynor ratios, which scale country excess returns by the estimated beta on the world wealth portfolio, also reveal substantial variation across countries in excess real estate returns per unit of systematic risk. However, when we estimate Jensens alphas using both single and multifactor specifications, we detect little evidence of abnormal, risk-adjusted returns at the country level. We do, however, find evidence of a strong world-wide factor in international real estate returns. Furthermore, even after controlling for the effects of world-wide systematic risk, an orthogonalized country-specific factor is highly significant. This suggests that real estate securities may provide international diversification opportunities.     

A Test of the Signaling Value of IPO Underpricing with REIT IPO-SEO Pairs

The asymmetric information hypothesis states that IPO underpricing signals superior firm value. During the post-IPO period, the market learns the firms true worth such that good quality firms issue seasoned equity at favorable prices and recoup the loss sustained at IPO. Since REITs have no special incentive to issue debt because of their tax-exempt status, and since they must pay out 95 percent of net income as dividends, REIT managers are hard pressed to raise capital through seasoned equity. Consequently, the signaling link between IPOs and SEOs is critical for REITs. Consistent with the signaling model, we find strong evidence that (1) REITs that underprice IPOs more are likely to sell seasoned equity sooner, (2) higher IPO underpricing results in larger joint amount of capital raised through an IPO-SEO pair, and (3) firms that underprice IPOs underprice SEOs as well. IPO underpricing does not mitigate the valuation loss associated with seasoned offerings, however.     

Pension Plan Investment Management Mandates: An Empirical Analysis of Manager Selection

We examine the impact of several factors on the selection of portfolio managers for Australian pension plan mandates. Performance measures do not affect the probability of a mandate allocation. Pension sponsors tend to choose managers with top-quartile five-year performance who have recently beaten a market benchmark. Management expenses have a negative impact on a managers chances. A surprising result is sponsors tolerance for high portfolio trading costs. Mandates are spread across manager investment styles. The style and institutional attributes of preferred managers suggest trustees reputation and prudential concerns matter, particularly for the aggregate annual mandate allocations.     

Information Monopoly and Commitment in Intermediary-Firm Relationships

A bank may use the private information that it acquires through monitoring to hold up borrowers. This information monopoly of the bank may inefficiently distort the borrowers investment decisions in environments where moral hazard is prevalent. The paper analyses how this problem is resolved within bank-firm relationships. In the benchmark case when the bank can contractually commit to future actions, the optimal contract turns out to be ambiguous in nature. When commitment contracts cannot be written, firms have an incentive to develop multiple banking relationships in order to decrease the inside banks bargaining power. However, with costly monitoring, this may defeat the initial purpose for contracting with a financial intermediary, namely information production. The paper argues that when contractual commitment is not feasible, bank size may serve as an alternative commitment device that prevents the bank from holding up borrowers in the future.     

Economic Effects of the 2003 Partial Integration Proposal in the United States

On January 7, 2003, President George W. Bush proposed a significant change in capital income taxation in the United States. In the context of a jobs and growth package, the President proposed to reduce substantially the double taxation of corporate-source income by eliminating investor-level taxes on dividends paid from earnings on which corporate tax had been paid. In addition, the Presidents proposal would have reduced the tax on retained earnings by allowing a basis adjustment for accumulated previously taxed retained earnings. Taken together, these proposals would have moved the U.S. income tax much closer to an integrated tax system along the lines outlined by the Treasury Department in President George H.W. Bushs administration a decade earlier.Putting together the impacts of the Presidents proposal on economic activity through greater capital accumulation and improved calculation, I estimate that the proposal, if it had been enacted in its original form, would yield a permanent increase of 0.48 percent in the U.S. economys potential output. This estimated gain does not include any gains made possible by improved corporate financial policy.At the time of the integration proposal, the author was Chairman of the Council of Economic Advisers.
