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.     

The marginal cost of public funds is one at the optimal tax system

This paper develops a Mirrlees framework with skill and preference heterogeneity to analyze optimal linear and nonlinear redistributive taxes, optimal provision of public goods, and the marginal cost of public funds (MCF). It is shown that the MCF equals one at the optimal tax system, for both lump-sum and distortionary taxes, for linear and nonlinear taxes, and for both income and consumption taxes. By allowing for redistributional concerns, the marginal excess burden of distortionary taxes is shown to be equal to the marginal distributional gain at the optimal tax system. Consequently, the modified Samuelson rule should not be corrected for the marginal cost of public funds. Outside the optimum, the marginal cost of public funds for distortionary taxes can be either smaller or larger than one. The findings of this paper have potentially important implications for applied tax policy and social cost–benefit analysis.     

The stimulative effects of intergovernmental grants and the marginal cost of public funds

This paper tests the hypothesis that the stimulative effects of intergovernmental grants increase with the marginal cost of public funds of the recipient government. We present a simple theoretical framework that shows how a lump-sum transfer stimulates the marginal expenditures of a recipient government through an income effect and a price effect. We then test the prediction of this model using Canadian provincial data and exploit the discontinuity in the equalization grants allocation formula to identify the effects of grants. Our results indicate that the stimulative effects of lump-sum grants on spending increase with the provincial government’s marginal cost of public funds (MCF). One policy implication of our results is that higher intergovernmental transfers may be welfare improving if the federal government has a lower MCF than the provinces.     

On the marginal cost of public funds: the implications of charitable giving and warm glow

This paper highlights the important impact of charitable giving and warm glow on the identification of the marginal cost of public funds (MCF). We employ the warm glow model of charitable giving to describe taxpayer behaviour, whereas we employ the standard model to evaluate social welfare. We first identify the impact theoretically. Then we conduct simulations to quantify its size numerically. The results of our numerical simulations show that the standard model underestimates the magnitude of MCF by at least 10 per cent. Our work suggests that adopting a non-welfarist social welfare function can make a significant difference to the identification of MCF.     

Insider ownership, ownership concentration and investment performance: An international comparison

This article makes two important contributions to the literature on the incentive effects of insider ownership. First, it presents a clean method for separating the positive wealth effect of insider ownership from the negative entrenchment effect, which can be applied to samples of companies from the US and any other country. Second, it measures the effects of insider ownership using a measure of firm performance, namely a marginal q, which ensures that the causal relationship estimated runs from ownership to performance. The article applies this method to a large sample of publicly listed firms from the Anglo-Saxon and Civil law traditions and confirms that managerial entrenchment has an unambiguous negative effect on firm performance as measured by both Tobin's (average) q and our marginal q, and that the wealth effect of insider ownership is unambiguously positive for both measures. We also test for the effects of ownership concentration for other categories of owners and find that while institutional ownership improves the performance in the USA, financial institutions have a negative impact in other Anglo-Saxon countries and in Europe.     

On "q"

The introduction of Tobin's q-ratio in the literature has prompted noteworthy advances in economic model-building and empirical analysis. A major shortcoming has been the lack of a convincing measure of marginal q. Herein an alternative approach for measuring marginal q is presented, one based on an event study of capital expenditure announcements. The measures of marginal q are shown to yield reasonable and consistent estimates. The marginal q variables perform well against the hypothesized relationships developed from q theory. A key result is that classifying firms according to their average q measures as a proxy for marginal q is likely to lead to misclassification problems.     

On Tail Value-at-Risk for sums of non-independent random variables with a generalized Pareto distribution

Recently in actuarial literature several authors have derived lower and upper bounds in the sense of convex order for sums of random variables with given marginal distributions and unknown dependency structure. In this paper, we derive convex bounds for sums of non-independent and identically distributed random variables when marginal distributions are mixture models. In particular, we examine some well-known risk measures and we find approximations for Tail Value-at-Risk of the sums considered when marginal distributions are generalized Pareto distributions. By numerical examples we illustrate the goodness of the presented approximations.      

Macroprudential Policies and Housing Prices: A New Database and Empirical Evidence for Central,Eastern, and Southeastern Europe

Several countries in Central, Eastern, and Southeastern Europe used a rich set of prudential instruments during the recent credit and housing boom and bust cycles. We construct a comprehensive database of these policy measures covering 16 countries at a quarterly frequency. We use this database to investigate whether the policy measures had an impact on housing price inflation. The measures that appeared to be effective were capital measures (minimum capital adequacy ratio, maximum ratio of lending to households to share capital) and nonstandard liquidity measures (marginal reserve requirements (MRRs) on foreign funding, MRRs linked to credit growth).     

The effects of tax rate changes on tax bases and the marginal cost of public funds for Canadian provincial governments

The efficiency losses from taxation vary directly with the responsiveness of a government??s tax bases to tax-rate increases. We estimate the dynamic responses of tax bases to changes in tax rates using aggregate panel data from Canadian provinces over the period 1972 to 2006. Our preferred empirical results indicate that a one percentage point increase in corporate income, personal income, and sales tax rates is associated with a 3.67, 0.76, and 1.17 percent reduction in their respective tax bases in the short run. The corresponding long-run tax base semi-elasticity estimates are higher: ?13.60, ?3.63, and ?3.18, respectively. We use the tax base elasticity estimates to calculate the marginal cost of public funds (MCF) for the provinces?? three major taxes. Our computations indicate that the corporate income had the highest MCF and that the sales tax had the lowest MCF in all provinces in 2006. The MCF for the personal income tax ranged from 1.44 in Alberta to 3.81 in Quebec. Our results imply that there would have been significant welfare gains in 2006 from reductions in provincial corporate income tax rates. Our computations also indicate that the equalization grant formula may reduce the perceived MCF of the provinces that receive these grants, and that increases in provincial corporate and personal income taxes can cause significant reductions in federal tax revenues.     

Estimating the basis risk of index-linked hedging strategies using multivariate extreme value theory

This paper studies the empirical quantification of basis risk in the context of index-linked hedging strategies. Basis risk refers to the risk of non-payment of the index-linked instrument, given that the hedger’s loss exceeds some critical level. The quantification of such risk measures from empirical data can be done in various ways and requires special consideration of the dependence structure between the index and the company’s losses as well as the estimation of the tails of a distribution. In this context, previous literature shows that extreme value theory can be superior to traditional methods with respect to estimating quantile risk measures such as the value at risk. Thus, the aim of this paper is to conduct an empirical analysis of basis risk using multivariate extreme value theory and extreme value copulas to estimate the underlying risk processes and their dependence structure in order to obtain a more adequate picture of basis risk associated with index-linked hedging strategies. Our results emphasize that the application of extreme value theory leads to better fits of the tails of the marginal distributions in the considered stock price sample and that traditional methods in regard to estimating marginal distributions tend to overestimate basis risk, while basis risk can in contrast be higher when taking into account extreme value copulas.     

The Multi-Period Cost-Benefit Rule with Mobile Capital and Distorted Labor

Lind (1990) argues that capital mobility should be incorporated into the discussions of the social discount rate. He finds that when labor market distortion is ignored in that context, the appropriate discount rate for both project benefits and costs is the net rate of return, and the gross rate of return does not enter into the rule. Taking into account the labor market distortion, we find that a projects impacts on government receipts should be incorporated into its evaluation and that costs should be multiplied by a marginal cost of funds (MCF) before being compared with benefits. Although the net rate continues to be the correct discount rate to use, the gross rate enters into the rule by having effects on the projects receipt impacts and the MCF.JEL Code: D61, H43, F21     

Children's Working Hours and School Enrollment: Evidence from Pakistan and Nicaragua

Although much of the literature on child labor looks at thedecision on whether to send a child to school or to work (orboth), little attention has focused on the number of hours worked.This article analyzes the determinants of school attendanceand hours worked by children in Pakistan and Nicaragua. A theoreticalmodel of children's labor supply is used to simultaneously estimatethe school attendance decision and the hours worked, using afull model maximum likelihood estimator. The model analyzesthe marginal effects of explanatory variables, conditioningon latent states, that is, the propensity of the household tosend the child to work or not. These marginal effects are insome cases rather different across latent states, with importantpolicy implications.     

Transfer Pricing, Incentive Compensation and Tax Avoidance in a Multi-Division Firm

This article examines the relation between transfer pricing and production incentives using a model of a vertically integrated firm with divisions located in different tax jurisdictions. We show that if divisional profits are taxed at the same marginal rate, the transfer price should be set to minimize the compensation risk faced by the manager of the buying division. For the case where divisional profits are taxed at different marginal rates, we are able to characterize the trade-off between the tax savings from setting transfer prices to reduce profitability in the high tax jurisdication and the loss of effort attributable to the impact of tax avoidance on the incentive compensation system. Further, we show that if it is feasible to compensate the division managers using multiple performance measures, the transfer price should be used to minimize the firm's overall tax liability. Finally, we show that when authority to determine the transfer price must be delegated to one of the division managers, it is optimal to assign responsibility for setting the transfer price to the manager of the division with the most production uncertainty.

Measuring the multi-faceted dimension of liquidity in financial markets: A literature review

This paper provides a thorough review of the liquidity measures that are used in the empirical literature to measure liquidity. A wide range of papers have emphasized its role and the need to manage and understand this topic, which had hitherto not been deeply explored. Literature on liquidity proposes a wide set of liquidity measures and proxies intended to measure the different characteristics and dimensions that liquidity presents. Early papers analyzing the liquidity issue were based on quotation data or on end-of-month prices, given that databases with widely complete transaction information were not available. The recent availability of high frequency databases has allowed researchers not only to develop new measures but also to adapt to other markets a comprehensive set of existing measures. In this paper, we classify and describe the variety of the existing liquidity measures and proxies depending on the aspect of liquidity that one wants to address.     

Inventory Investment and the Empirical Phillips Curve

In this paper, we study the Calvo pricing models with finished goods inventory investment to demonstrate that the current inflation can be expressed as a function of the marginal cost of sales, not the marginal production cost, and expected future inflation. Under the assumption that the true aggregate marginal costs are not observable in actual data, we make use of equilibrium conditions for aggregate finished goods inventories to measure the time series of marginal costs, thereby leading to the construction of inflation series on the basis of the Phillips curve. Our results indicate the possibility of a successful fit of the empirical New Keynesian Phillips curve without relying on unit labor cost—a conventional measure of marginal production cost in the literature.     

Technology,Utilization, and Inflation: What Drives the New Keynesian Phillips Curve?

We argue that the New Keynesian Phillips Curve literature has failed to deliver a convincing measure of real marginal costs. We start from a careful modeling of optimal price setting allowing for nonunitary factor substitution, nonneutral technical change, and time‐varying factor utilization rates. This ensures the resulting real marginal cost measures match volatility reductions and level changes witnessed in many U.S. time series. The cost measure comprises conventional countercyclical cost elements plus procyclical (and covarying) utilization rates. Although procyclical elements seem to dominate, the components of real marginal cost components are becoming less cyclical over time. Incorporating this richer driving variable produces more plausible price‐stickiness estimates than otherwise and suggests a more balanced weight of backward‐ and forward‐looking inflation expectations than commonly found. Our results challenge existing views of inflation determinants and have important implications for modeling inflation in New Keynesian models.     

The Welfare Returns to Finer Targeting: The Case of The Progresa Program in Mexico

It is common in developing countries to attempt finer targeting of the benefits from social safety net programs through combining different targeting methods. We evaluate the returns to finer targeting in the context of the PROGRESA program in Mexico. This program is a prominent program in the literature reflecting the fact that it has been widely evaluated, is perceived to be well targeted, and has been used as a prototype for many other programs in the region and beyond. We also identify the relative incremental contribution of each targeting method to the overall targeting performance of the program. We find that geographic targeting dominates demographic targeting (based on linking transfer levels to demographic composition), which in turn dominates household proxy-means targeting. However, the contribution of proxy-means targeting increases substantially as the program expands into less marginal localities. Adjusting for incomplete take-up increases the targeting performance of the program only slightly.

Debt shifting in Europe

This article aims to analyze the link between subsidiary capital structure and taxation in Europe. First we have introduced a trade-off model, which looks at a MNC’s financial strategy and in particular debt shifting from low-tax to high-tax jurisdictions. By letting the MNC choose both leverage and the debt shifting percentage, we depart from the relevant literature which has mainly focused on the latter. Using the AMADEUS dataset we show that: (i) in line with the relevant literature, subsidiary leverage increases with its tax rate; (ii) contrary to previous work, the parent company tax rate does not have a negative effect on subsidiary leverage. More specifically, its effect is estimated to be nil when statutory tax rates are used. When however, effective marginal tax rates (EMTRs), accounting for cross-border effects, are used, the impact of parent company taxation on subsidiary leverage is positive.     

JOINT PRODUCT DECISIONS, THE FIXED PROPORTIONS CASE: A NOTE

The purpose of this note is to draw attention to a misleading conclusion in the literature, that in determining the optimal rate of joint production and the optimal quantities of joint products to be finished and sold, the joint costs are implicitly shared in proportion to the respective marginal revenues. This conclusion applies only to a special case which is not typical of most joint production processes.
