product risk asymmetric information and trade credit the purpose of this paper is to explain cross sectional variations in trade credit terms across firms and industries this study shows that there is a separating equilibrium in which the size of the cash discount conveys information about product quality the driving forces of this equilibrium outcome are the risk sharing motives of the producer and buyer as well as asymmetric information about product quality the empirical implications of the model are derived and discussed in relation to industry practices

a derivation of the marginal abatement cost curve abstract the relationship between a firm s technology and its marginal abatement cost mac curve is explored even under the simplest specifications the mac curve will be kinked at some point except under a special assumption which in reality could easily be violated the nondifferentiability implies that the choice of instrument under uncertainty may depend on the targeted level of emissions reduction also stability conditions for dynamic tax mechanisms may be violated in the neighborhood of the kink point a policy implication is that in some cases output restrictions are as efficient as emissions restrictions in contrast to previous results

accounts receivable management policy theory and evidence this paper develops and tests hypotheses that explain the choice of accounts receivable management policies the tests focus on both cross sectional explanations of policy choice determinants as well as incentives to establish captives we find size concentration and credit standing of the firm s traded debt and commercial paper are each important in explaining the use of factoring accounts receivable secured debt captive finance subsidiaries and general corporate credit we also offer evidence that captive formation allows more flexible financial contracting however we find no evidence that captive formation expropriates bondholder wealth firms typically sell merchandise on credit rather than requiring immediate cash payment such credit sales generate accounts receivable although credit terms and credit collection procedures have been studied see smith 1980 there has been little systematic analysis of the organizational and financial structures employed to manage the firm s accounts receivable these decisions merit more careful attention for two reasons first receivables are a substantial fraction of corporate assets for example 1986 compustat data indicate that accounts receivable are 21 0 of u s manufacturing corporations total assets second we observe substantial diversity in firms use of specialized contracts and intermediaries in their accounts receivable management policies firms can 1 establish a captive finance subsidiary 2 issue accounts receivable secured debt 3 factor 4 employ a credit reporting firm 5 retain a credit collection agency or 6 purchase a credit insurance policy 1 in this paper we demonstrate that accounts receivable management policy offers opportunities for both the development of a robust theory as well as empirical testing of the theory s implications although the data necessary to

sustaining production chains through financial linkages abstract the technological constraints on sustaining production chains have been discussed extensively by development economists but the role of financial linkages has received less attention in a model of recursive moral hazard for a manufacturing supply chain we show that the structure of interlocking receivables and payables serve as the glue for the production chain that sustains complex manufacturing output the inefficiency associated with recursive moral hazard can be mitigated through optimal delays in payments along the chain however efficiency requires large stocks of working capital and invoice prices are high due to implicit amortization costs of inter firm credit

what are the key drivers of mac curves a partial equilibrium modelling approach for the uk marginal abatement cost mac curves are widely used for the assessment of costs related to co2 emissions reduction in environmental economics as well as domestic and international climate policy several meta analyses and model comparisons have previously been performed that aim to identify the causes for the wide range of mac curves most of these concentrate on general equilibrium models with a focus on aspects such as specific model type and technology learning while other important aspects remain almost unconsidered including the availability of abatement technologies and level of discount rates this paper addresses the influence of several key parameters on mac curves for the united kingdom and the year 2030 a technology rich energy system model uk markal is used to derive the mac curves the results of this study show that mac curves are robust even to extreme fossil fuel price changes while uncertainty around the choice of the discount rate the availability of key abatement technologies and the demand level were singled out as the most important influencing factors by using a different model type and studying a wider range of influencing factors this paper contributes to the debate on the sensitivity of mac curves

policy variability productive spending and growth in this paper i present two models with policy variability arising from randomness in the provision of productive public spending in the first model public spending enters as an input in output production in this case i find that the relationship between policy variability and growth depends critically on the technological parameters of the production function in the second model public spending enters as an input in the education sector of the economy in this case i find that policy variability retards growth as individuals respond to increased uncertainty by actually reducing rather than increasing their investment in human capital

trade credit and informational asymmetry commonly used trade credit terms implicitly define a high interest rate that operates as an efficient screening device where information about buyer default risk is asymmetrically held by offering trade credit a seller can identify prospective defaults more quickly than if financial institutions were the sole providers of short term financing the information is valuable in cases where the seller has made nonsalvageable investments in buyers since it enables the seller to take actions to protect such investments traditional explanations for the widespread use of trade credit fall into two categories the financing motive holds that capital market imperfections enable sellers to finance buyer purchases at lower cost than financial institutions ferris 4 argues that trade credit provides payment flexibility and thus reduces the overall need for buyers and sellers to maintain precautionary balances emery 3 contends that noncompetitive rents of financial institutions can be circumvented by sellers and buyers through provision of trade credit however the financing motive is not sufficient to explain why small suppliers offer trade credit the wide cross sectional variation in terms or why large buyers often take the prompt payment discount late a second set of explanations is best described as pricing motivations for trade credit provision nadiri 10 argues that availability of alternative payment terms can increase product demand but does not indicate why the offered terms could not be duplicated by financial institutions schwartz and whitcomb 14 argue that trade credit is used to circumvent robinson patman and similar prohibitions on price discrimination the correctness of this position depends on the charge to users of trade credit exceeding the cost of provision by the seller although the explanation is possible in principle an empirical question remains as to why variations in actual credit terms appear to be based on product market rather than buyer characteristics the literature also contains analyses of the impact of changing macroeconomic conditions on trade credit terms and aggregate credit flows schwartz 13 for example employs a financing motive for trade credit to conclude that restrictive monetary policy can be partly mitigated by liberalization of trade credit terms by firms with relatively easy access to capital markets however a microeconomic

environmental innovation and the cost of pollution abatement revisited it is widely assumed in the literature that environmental innovation reduces the marginal cost of pollution abatement in this paper we show that this is not necessarily the case and we provide some unexpected outcomes

the hotspots reference routes and research trends of marginal abatement costs a systematic review abstract as one of the most effective means of evaluating environmental policies marginal abatement costs macs have been adopted in a growing body of research this study characterizes the mac related literature from 1993 to 2018 on web of science based on a systematic review bibliometric analysis and mind mapping the results classify the research hotspots into influential factors methods and empirical applications the three most frequently mentioned influential factors are technical change discount rates and energy prices compared with top down models bottom up models including engineering model and expert based method are the most widely used improvements in the former focus on strengthening market behavior effect while those in the latter aim to overcome the weaknesses of negative costs and lack of interaction across measures mac applications focus on environmental policies with two new research areas recently emerging co benefits and sectoral abatement costs furthermore a reference route is proposed by summarizing the applicability of methods and matching relationships among influential factors methods and empirical problems finally potential research directions are summarized based on the identified research hotspots and a similar co word analysis in marginal cost field such as considering the effects of both multiple influential factors and the interaction among factors on maccs

the implicit costs of trade credit borrowing by large firms we examine a novel but economically important characterization of trade credit relationships in which large investment grade buyers borrow from their smaller suppliers using a matched sample of large retail buyers and their much smaller suppliers we find that slower payment terms by large retailers are associated with lower investment at the supplier level the effects are sharpest during periods of tight bank credit and for firms which we might otherwise characterize as financially constrained the opportunity cost of extending credit to large buyers appears to be positive and sharply increasing in the financial frictions facing a firm

the international transmission of financial shocks the case of japan one of the more dramatic financial events of the late 1980s and early 1990s was the surge in japanese stock prices that was immediately followed by a very sharp decline of more than 50 percent while the unprecedented fluctuations in japanese stock prices were domestic financial shocks the unique institutional characteristics of the japanese economy produce a framework that is particularly suited to the transmission of such shocks to other countries through the behavior of the japanese banking system the large size of japanese bank lending operations in the united states enables us to use u s banking data to investigate the extent to which this domestic japanese financial shock was transmitted to the united states as well as to identify a supply shock to u s bank lending that is independent of u s loan demand we find that binding risk based capital requirements associated with the decline in the japanese stock market resulted in a decline in commercial lending by japanese banks in the united states that was both economically and statistically significant this finding has added importance given the severe real estate loan problems currently faced by japanese banks how japanese bank regulators decide to resolve these problems will have significant implications for credit availability in the united states as well as in other countries with a significant japanese bank presence

buyer intermediation in supplier finance small suppliers often face challenges to obtain financing for their operations especially in developing economies traditional financing methods can be very costly or unavailable to such suppliers to reduce channel costs large buyers have recently begun implementing their own financing methods that intermediate between suppliers and financing institutions in this paper we analyze the role and efficiency of buyer intermediation in supplier financing building a game theoretical model we show that buyer intermediated financing can significantly improve channel performance and can simultaneously benefit both supply chain participants using data from a large chinese online retailer and through structural regression estimation we demonstrate that buyer intermediation lowers interest rates and wholesale prices increases order fill rates and boosts supplier borrowing based on counterfactual analysis on the data we predict that the implementation of buyer intermediated financing will improve channel

does technological innovation really reduce marginal abatement costs some theory algebraic evidence and policy implications the existing literature models innovation in pollution control as a reduction in marginal abatement costs we show that this assumption is inappropriate for production process innovations such as fuel switching algebraically we examine the effects of different innovation types on marginal abatement cost curves showing that some desirable innovations increase marginal abatement costs empirically we estimate marginal abatement costs for sulfur dioxide by measuring the output distance function for electric power in korea regression results confirm that production process innovations did raise marginal abatement costs in this case one policy implication economic instruments do not always provide stronger innovation incentives than command and control policies

quantifying co2 abatement costs in the power sector co2 cap and trade mechanisms and co2 emission taxes are becoming increasingly widespread to assess the impact of a co2 price marginal abatement cost curves maccs are a commonly used tool by policy makers providing a direct graphical link between a co2 price and the expected abatement however such maccs can suffer from issues related to robustness and granularity this paper focuses on the relation between a co2 emission cost and co2 emission reductions in the power sector the authors present a new methodology that improves the understanding of the relation between a co2 cost and co2 abatement the methodology is based on the insight that co2 emissions in the power sector are driven by the composition of the conventional power portfolio the residual load and the generation costs of the conventional units the methodology addresses both the robustness issue and the granularity issue related to maccs the methodology is based on a bottom up approach starting from engineering knowledge of the power sector it offers policy makers a new tool to assess co2 abatement options the methodology is applied to the central western european power system and illustrates possible interaction effects between e g fuel switching and renewables deployment

technical change and the marginal cost of abatement abstract we address one aspect of the treatment of technical change in the environmental economics literature how technical change impacts the marginal cost of abatement we review a selection of papers that employ a variety of representations of technical change and show that these representations have quite different and sometimes surprising effects on the marginal costs of pollution reductions we argue that these varied representations in fact correspond to a variety of different technology options we then present results indicating that this representation matters the impacts of technical change on the marginal cost of abatement can crucially impact policy analysis

trade credit and the bank lending channel the bank lending channel theory posits that during monetary contractions banks restrict some firms loans thus reducing their desired investment independently of interest rates previous research finds small firms reduce while large firms accelerate loan growth we find that small firms increase trade credit a substitute credit indicating a strong loan demand it supports the bank lending channel they do not voluntarily cut bank loans since they increase a less desirable alternative using trade credit is propitious since unlike commercial paper investigated by previous researchers it is widely used by the small firms suffering the loan decline surprisingly we also find large firms increase trade credit a puzzle since they are typically assumed to have wide access to other credit using individual manufacturing firm data we find the reasons large firms use trade credit are financial in nature those without a bond rating increase trade credit that is without access to open market credit as relatively few firms have this mark of quality it implies that more firms are affected by credit constraints than previously believed

climate policies for road transport revisited ii closing the policy gap with cap and trade current policies in the road transport sector fail to deliver consistent and efficient incentives for greenhouse gas abatement see companion article by creutzig et al in press market based instruments such as cap and trade systems close this policy gap and complement traditional policies that are required where specific market failures arise even in presence of strong existing non market policies cap and trade delivers additional abatement and efficiency by incentivizing demand side abatement options this paper analyzes generic design options and economic impacts of including the european road transport sector into the eu ets suitable points of regulation are up and midstream in the fuel chain to ensure effectiveness cover all emissions and avoid double counting efficiency incentivize all abatement options and low transaction costs based on year 2020 marginal abatement cost curves from different models and current eu climate policy objectives we show that in contrast to conventional wisdom road transport inclusion would not change the eu ets allowance price hence industrial carbon leakage induced by adding road transport to the eu ets may be less important than previously estimated

an assessment of household electricity load curves and corresponding co2 marginal abatement cost curves for gujarat state india gujarat a large industrialized state in india consumed 67 twh of electricity in 2009 10 besides experiencing a 4 5 demand supply short fall residential sector accounted for 15 of the total electricity consumption we conducted load research survey across 21 cities and towns of the state to estimate residential electricity load curves share of appliances by type and usage patterns for all types of household appliances at utility geographic appliance income and end use levels the results indicate that a large scope exists for penetration of energy efficient devices in residential sector marginal abatement cost mac curves for electricity and co2 were generated to analyze relative attractiveness of energy efficient appliance options results indicate that up to 7 9 twh of electricity can be saved per year with 6 7 mt co2 emissions mitigation at negative or very low co2 prices of us 10 t co2 despite such options existing their penetration is not realized due to myriad barriers such as financial institutional or awareness and therefore cannot be taken as baseline options for co2 emission mitigation regimes

marginal abatement costs of greenhouse gas emissions a meta analysis in this paper we carry out a meta analysis of recent studies into the costs of greenhouse gas mitigation policies that aim at the long term stabilisation of these gases in the atmosphere we find the cost estimates of the studies to be sensitive to the stringency of the stabilisation target the assumed emissions baseline the way in which the time profile of emissions is determined in the model the choice of control variable co2 only versus multigas the number of regions and energy sources in the model and to a lesser degree the scientific forum in which the study was developed we find that marginal abatement costs of the stringent long term targets that are currently considered by the european commission are still very uncertain but might exceed the costs that have been suggested by recent policy assessments

marginal abatement costs of co2 emission reductions geographical flexibility and concrete ceilings an assessment using the poles model abstract the kyoto protocol envisage the setting up of flexibility mechanisms allowing annex b countries to fulfil their commitments to reducing greenhouse gases with respect for the principle of economic efficiency the current negotiations relate in particular to the possibility of setting up a system of tradable emissions permits for annex b countries and also of introducing ceilings to trade this paper analyses the stakes and economic potential of adopting this instrument both for those countries that made commitments in kyoto and for developing countries it is based on a formal approach that allows for a consistent framework of analysis the emission permit market is in fact simulated on the basis of a reference scenario and of marginal abatement cost curves and estimated by the poles model after analysing these marginal abatement cost curves and comparing them with those produced by other models we explore two different configurations for a competitive market a market limited to the annex b countries and a world market the results produced by the model show that widening the market to include developing countries is more effective than the annex b market solution it reduces the cost of implementing kyoto for oecd countries and at the same time allows the countries of the south to benefit from selling the permits this research also shows that introducing restrictions on exchanges for annex b countries could have a counter productive redistribution effect with the ethical argument that underlies that particular measure

interest rates in trade credit markets all things equal interest rates should increase with the borrower s risk and yet klapper laeven and rajan 2012 cannot find such a positive relation in a broad sample of trade credit contracts we shed some light on this puzzle by arguing that competition between informed and uninformed suppliers weakens the link between the trade credit cost and the borrower s creditworthiness our model implies that trade credit rates are more likely to increase with the borrower s risk if suppliers are less profitable have high cost of funds or sell inputs to firms plagued by moral hazard and financial distress

choosing a monetary value of greenhouse gases in assessment tools a comprehensive review there is a societal need for using monetary estimates of social impacts of co2 and other greenhouse gases in different assessment tools such as cost benefit analysis and life cycle assessment a number of estimates are available in the literature since these differ by several orders of magnitude there is ambiguity and confusion about which to use this review aims to give some guidance on this issue the variation in carbon value estimates depends on several uncertain aspects which will remain uncertain including climate sensitivity assumptions about future emissions and decision makers ethical standpoints hence there is no single correct monetary value for co2 it will depend on the ethical standpoint of the user due to this estimates of social costs of co2 emissions cannot be used for calculating an optimal emission level although they can inform such assessments it is suggested that marginal abatement cost values are used for emissions capped by binding targets in short term assessments and that social cost of carbon values should be used for all other emissions benchmark principles for choosing a monetary carbon value are suggested along with associated estimates depending on the choices made with regard to ethical standpoints and assumptions about future emissions and climate sensitivity estimates can be significantly higher than the ones typically used in assessment tools today the estimates need continuous updating and there is need for better understanding and communication around the limitations and uncertainties involved

innovation in pollution control comparisons of the various institutional arrangements for controlling pollutant emissions from individual sources effluent fees effluent control subsidies marketable permits and direct command and control regulation have usually focused on their static efficiency properties and institutional feasibility e g dales 1968 zerbe 1970 baumol and oates 1975 kneese and schultze 1975 marin 1978 mills and white 1978 spence and weitzman 1978 russell 1979 a relatively neglected area has been the study of how each arrangement influences innovation in pollution control a few studies e g kneese and schultze 1975 marin 1978 mills and white 1978 russell 1979 have casually claimed that the control methods that rely on economic incentives provide superior incentives for innovation but there have been few systematic studies of the question this paper provides a simple model of pollution control innovation by a profitmaximizing polluter who is subject to the various control methods the consequences of the methods will be explored in three major contexts first we assume that the polluter and the innovation is a small enough part of the overall pollution problem so that none of the important marginal conditions are changed by the innovation second we assume that the polluter and the innovation are important enough so that marginal conditions are changed by the innovations but that the governmental authority determining pollution control incentives or levels fails to make the appropriate adjustments third we again assume that the innovation causes marginal conditions to change but in this case the governmental authority makes the appropriate adjustments we use the term ratcheting to describe this last phenomenon in all cases we assume that the innovating polluter correctly predicts the reactions of the governmental authority and bases his innovation decisions on that prediction a profit maximizing entrepreneur would normally be expected to adopt any innovation that promised gains present discounted value to him in excess of initial

the applicability of marginal abatement cost approach a comprehensive review abstract the marginal abatement cost mac methodology is widely used in climate change policies policy makers rely on mac to assess feasible strategies and related costs to achieve emission reduction goals this paper introduces a variety of mac methodologies aiming at solving diverse problems which utilizes various calculable logic thus producing different results and implications this study applies a mind mapping method to capture differentiation of mac methods and systematically classify mac methodologies the applicability path analysis was proposed based on principles such as stakeholder type decision making objectives cost concept strategy mode and information scope our goal is to assess the applicability of different methodologies to reduce misuse by policy makers and to serve as a guide for subsequent research which might prompt and lead to the derivation of more consequential results in future studies the results of this study suggest that the complex method is not always better than the simplified method because policy makers are required to select the appropriate method according to the type of information needed it may even be suggested that mac could be reliable by ranking relative value of options compared with baseline rather than focusing on the absolute value of individual measures

does the source of capital affect capital structure prior work on leverage implicitly assumes capital availability depends solely on firm characteristics however market frictions that make capital structure relevant may also be associated with a firm s source of capital examining this intuition we find firms that have access to the public bond markets as measured by having a debt rating have significantly more leverage although firms with a rating are fundamentally different these differences do not explain our findings even after controlling for firm characteristics that determine observed capital structure and instrumenting for the possible endogeneity of having a rating firms with access have 35 more debt copyright 2006 oxford university press
