A review of: “ANALYTICAL TECHNIQUES FOR FINANCIAL MANAGEMENT,” by Jerome S. Osteryoung and Daniel E. HcCarty,Grid Publishing Co., Columbus,Ohio, 1980, xii + 316 pages,paperback, list $10.95

Recently, Formato derived a useful formula of the amount of periodic equal payment in a skip payment loan with arbitrary skips using a second-order finite difference equation. We rederive his formula using simple arithmetics and provide an intuitive explanation of the formula. We also extend his result to the case that periodic payments occur in a geometric-gradient-series.     

Down Payment Saving in the United States: Evidence from the Panel Study of Income Dynamics

We present a model of household saving toward a mortgage loan under an exogenous down payment requirement and preference for owning over renting. Our model explains a set of empirical observations such as the dual effect in the form of some households, in response to higher down payments, becoming discouraged savers while those who do not abandon purchasing plans save more. We also employ instrumental variable‐based methods to investigate the down payment saving behavior of first‐time home buyers in the United States. The empirical results based on Panel Study of Income Dynamics (PSID) data support the inelastic down payment elasticity of saving implied by our model.     

Modeling the Korean Chonsei Lease Contract

Chonsei is a unique Korean lease contract in which the tenant pays an up–front deposit, typically about 40 to 80% of the value of the property, with no requirement for periodic rent payments. At the contract maturation, the landlord then returns the nominal value of the deposit. Since there is no legal obligation on the part of the landlord to deposit the money in an escrow account, the principal default risk associated with the chonsei contract falls on the tenant. We discuss the development and popularity of this contractual agreement in the context of the public policy initiatives, historical and institutional settings surrounding the Korean housing and housing finance market. We develop a contingent–claims model that recognizes the compound options embedded in the chonsei contract. Theoretical predictions are confirmed by an empirical analysis using monthly data from 1986 to 2000. Our analysis shows that the chonsei contract is an indigenous market response to economic conditions prevalent in Korea.     

Payment choice of M&As: Financial crisis and social innovation

The payment choice of mergers and acquisitions (M&As) influences firm performance and facilitates wealth transfer to shareholders and realises synergy through stakeholders' implicit contract. This study examines the choice of payment methods and firm-level characteristics of UK M&As during the financial crisis referring to the business-to-business (B2B) market in a broader sense. Further, conceptualising social innovation as a process-outcome-value construct, this study evaluates the choice of payment methods and firm-level characteristics of M&As through the lens of corporate social responsibility (CSR). The findings suggest that a stock payment method is favoured well over a cash payment method by the acquirers of M&A firms and firms that are pursuing social innovation through CSR activities. The results further document that a volatile market affected by the financial crisis reacts to the financing choice of M&As, making a sizable impact on firms' capital structure, ownership concentration, and asymmetric information. Acquiring firms that opt for stock payment methods register a significant increase in their firm-level characteristics, such as market-to-book-value, deal value, growth, and CARs compared to the cash payment method deals.     

The Effect of Mortgage Payment Reduction on Default: Evidence from the Home Affordable Refinance Program

This article evaluates the effect of payment reduction on mortgage default within the context of the Home Affordable Refinance Program. We find that mortgage default is sensitive to payment reduction using univariate, duration and hazard modeling approaches. A relative risk Cox model of default with time‐varying covariates estimates that a 10% reduction in mortgage payment is associated with about a 10–11% reduction in monthly default hazard for loans. This finding is robust to the inclusion of empirically important mortgage risk drivers (such as current loan‐to‐value and FICO score) as well as controlling for selection effects based on observables.     

A Review of: “ECONOMIC ANALYSIS FOR HIGHWAYS” By Robley Winfrey International Textbook Company 1969 923pp. $17.50

Five of the seven factors in most common use for compound interest calculations involve a uniform series of payments (or receipts). These interest factors, for use when interest is compounded at discrete points in time, are commonly referred to as the uniform series present worth factor, the uniform series compound amount factor, the capital recovery factor, the sinking fund factor and the uniform series gradient conversion factor. The proper use of these five factors requires that the period of time between the compoundings of interest coincide with the period of time between the uniform payments. If the interest is compounded more frequently (assume by an integer number of times) than the payments, then the best way to apply the compound interest factors is to determine the effective interest rate between payments. If interest is compounded less frequently than the payments (assume there are an integer number of payment periods within each compounding period), the correct solution procedure is not well known. Three methods are discussed for solving problems when interest is compounded less frequently than payments are made. It is argued that the method proposed in this note is better than the other two methods in popular use from both a theoretical and practical standpoint.     

Payment Evasion

This paper shows that a firm can use the purchase price and the fine imposed on detected payment evaders to discriminate between unobservable consumer types. Assuming that consumers self‐select into regular buyers and payment evaders, we show that the firm typically engages in second‐degree price discrimination in which the purchase price exceeds the expected fine. In addition, we find that higher fines do not necessarily reduce payment evasion. We illustrate with data from fare dodging on public transportation.     

The Flexible Mortgage: Optimal Financing of a Consumer Durable

Given the recent flood of new mortgage innovations, it is natural to wonder what features a mortgage which is "optimal" from the consumer's point of view might possess. This paper investigates this issue, using optimal control theory to characterize the time profile of mortgage payments (as well as the value of the mortgage) that maximizes an intertemporal utility function. Among other things, the analysis shows that the optimal mortgage payment stream rises over time under reasonable assumptions, highlighting the non-optimality of the standard flat-payment mortgage.     

Sufficient nourishment worldwide via transfer payments

The paper illustrates an unconventional approach to providing adequate nourishment worldwide. Regions with an insufficient calorie supply receive transfer payments in order to increase their food budgets. The transfer payments are financed by a flat income tax in OECD countries. A general equilibrium model, which contains this transfer payment mechanism as well as information about nutrition, is applied for the analysis. The resulting tax rate is 0.55% of OECD countries’ income or a required total transfer of 112 billion USD. With the money allocated the receiver regions boost their domestic production as well as increasing their food imports. This in turn affects agriculture in OECD countries by promoting production.     

Who bribes? Evidence from the United Nations' oil-for-food program

How do managers react in an environment where bribery is likely to bring high rewards, but also presents high risks? We examine the supply side (firms' illicit payments) of bribery in a global setting, using the United Nations' (UN) Oil-for-Food Program, part of UN sanctions on Iraq. Some companies helped Iraq circumvent UN sanctions through bribe payments in the form of illicit surcharges. Our transaction-level analysis of factors affecting bribe payments draws on the economic theory of crime, agency theory, and home country institutions. Results suggest that firms pay larger bribes when there are stronger financial and managerial incentives, but pay less when their home countries have implemented the OECD Anti-Bribery Convention. We find little relationship between a widely used country-level corruption perception index and firms' actual bribery. Copyright © 2012 John Wiley & Sons, Ltd.     

Payment by Results Systems: British Evidence

A model of the firm's decision to adopt a payment by results system is developed and tested with British establishment data. The model maintains that payment by results systems have larger set-up costs but lower supervision costs than time rates, particularly for short-tenure workers who are not well motivated by deferred compensation. The evidence confirms the model's predictions by showing that payment by results systems substitute for supervision, and that larger establishments and those with shorter-tenure workers are more likely to adopt payment by results. In addition, both the presence of a payment by results system and the new adoption of such a system are shown to exert a positive influence on measures of establishment performance.     

An estimate of the average cumulative royalty yield in the world mobile phone industry: Theory,measurement and results

An influential literature argues that dispersed patent ownership may lead to royalty stacking and excessive running royalties, thus increasing the long-run marginal cost of manufacturing phones and their prices. One set of estimates claims that the royalty stack is on the order of 20–40 percent of the value of the average phone. In order to assess this claim, we estimate the average cumulative royalty yield—the sum total of patent royalty payments earned by licensors, divided by the total value of mobile phones shipped— in the world mobile phone industry between 2007 and 2016.We “follow the money” and identify, with varying accuracy, 39 potential licensors in the smartphone value chain. We find that, of these, only 29 charged royalties in 2016, running from a low of $1.6 million to a high of $7.7 billion, summing to $14.2 billion in total, which compares with $425.1 billion in mobile phone sales. The average cumulative royalty yield in 2016 was 3.3 percent or $7.20 per phone. If we restrict this only to smartphones, the result would be $9.60 per phone, roughly 3.4 percent of the average selling price. A sensitivity analysis shows that even under a very restrictive set of assumptions, the average cumulative royalty yield on a smartphone would not exceed 5.6 percent.     

The HAMP NPV Model: Development and Early Performance

The foreclosure crisis that began in 2008 triggered the need for new approaches to treat distressed mortgages. A key component of the Obama Administration's Home Affordable Modification Program (HAMP) was the development of a standardized Net Present Value (NPV) Model to identify troubled loans that were value‐enhancing candidates for payment‐reducing modifications. This article discusses the development of the HAMP NPV Model, 1 its purpose and some important constraints that dictated its structure and limitations. We describe the structure and the estimation of the model in detail. We also describe the responsiveness of the model to key characteristics, such as loan‐to‐value and credit score, as well as provide new evidence on the relationship between HAMP modification performance and key borrower and modification characteristics. The article concludes with a discussion of model limitations and the future role of systematic loan modification using NPV analysis.     

Investment Project Valuation: A New Equity Perspective

We suggest a new approach to calculating a project's net present value, termed the displaced equity method. Based on a straightforward formula, it analyzes a project partially financed with debt from the perspective that every year the amount of outstanding debt displaces an equivalent amount of equity that otherwise would be tied up in the project. Although they represent distinct shareholders' perspectives, the displaced equity method and the equity residual method yield identical net present values and internal rates of return. Every year, the project's value calculated with the displaced equity method is equal to the sum of the project's debt and equity values. In practice, when the schedule of expected outstanding debt amounts is known, using the displaced equity method is an easy way to estimate the project's net present value.     

Why Do We Have ARMs?

This paper suggests a resolution to the paradox of inefficient risk bearing by adjustable-rate mortgage (ARM) borrowers. The analysis shows that when contracts are written in a realistic way, with payments linked across time via a common loan-rate function, risk sharing and the tilt of the mortgage payment stream become inextricably linked. Unless time preferences are identical or the cost of funds exhibits no time trend, borrowers will accept interest-rate risk in order to gain a more favorable time path of mortgage payments.     

The Optimal Mortgage Payment Path Under Price Uncertainty

It has been shown that in a world of certainty, individuals with rising income streams will choose a graduated payment mortgage over the standard flat payment mortgage. The present paper extends this analysis by introducing uncertainty about future inflation rates. We show that the risk-averse individual, when faced with uncertainty, will choose a less graduated payment path than in the certainty situation. While not conclusive, the analysis may cast some doubt on the suboptimality of the standard flat payment mortgage.     

Estimating switching costs involved in changing mobile phone carriers in Japan: Evaluation of lock-in factors related to Japan’s SIM card locks

This paper employs a web-based conjoint-type questionnaire to examine empirically user preference for a hypothetical Subscriber Identity Module (SIM) unlock situation in Japan’s mobile phone market. This paper also analyzes carriers’ other marketing strategies to lock in consumers. The empirical analysis in this study reveals the following: over 80% of survey respondents evaluate a highly compatible platform with the SIM unlocked. Approximately 70% of consumers find that the value of discounts on initial payments exceeds the discounts on one-year monthly payments. In addition, conditions set by continuing agreements for mobile carriers and mobile handsets reduce consumer benefit by 35% at the median in the case of SIM unlocking with compatible platforms.     

A Review of: “UNCERTAINTY AND ITS EFFECT ON CAPITAL INVESTMENT ANALYSIS,” by Martin B. Solomon,Jr. Management Science,Volume 12, No. 8, April 1966

In this paper we extend Thompson's [17] work using time series models within the discounted cash flow framework to estimate the cost of equity capita] for a firm. In particular we do the following: First, we prove the existence and uniqueness of a solution for the cost of equity capital. Secondly, we verify that the cost of equity function is continuously differentiable and derive the formula for its reliability. Formulas for both the cost and its reliability are in terms of infinite sums or infinite dimension matrices. Thirdly, we derive estimators of the cost of equity capital and its reliability which are in terms of finite sums and easy to calculate. We show that these estimated converge to the cost of equity capital and its reliability. Finally, our procedure for estimation applies to a wide variety of time series models that may be used to forecast dividends.     

Payment Systems and Interchange Fees

In a typical bank credit card transaction, the merchant's bank pays an interchange fee , collectively determined by all participating banks, to the cardholder's bank. This paper shows how the interchange fee balances charges between cardholders and merchants under imperfect competition. The privately optimal fee depends mainly on differences between cardholders' and merchants' banks, not their collective market power. In a non-extreme case, the profit-maximizing interchange fee also maximizes total output and producers' plus consumers' surplus. There is no economic basis for favoring proprietary payment systems, which do not need interchange fees to balance charges, over the cooperative bank card systems.     

知识工作设计与知识型员工薪酬策略

从系统性、授权度与自由度三个维度讨论了知识工作设计，基于工作与薪酬的双重激励效用，利用委托代理方法分析了知识工作设计与薪酬机制间的关系．最后讨论了知识型员工的薪酬策略。研究表明，上述三个维度的工作设计可适应知识工作的复杂性、满足知识型员工的需求；增加三个维度的水平．工作的复杂性将增加．并能激励员工付出更高的努力水平，但复杂性不能超出员工的能力范围。否则工作设计将得不偿失：工作的复杂性增加时必须增加薪酬激励强度，并增加效益工资与基本工资的比值．但对于复杂性过高的工作，则应降低其比值；员工的薪酬水平决定于其工作价值。
