estimating the tax advantage of corporate debt this paper presents estimates of the effective tax value of incremental interest deductions for corporations taking into account that they may not be able to utilize all their interest deductions fully because of either insufficient taxable income or the availability of nondebt tax shields after describing particular features of the tax code which may drive a wedge between statutory and effective tax rates for debt finance we present estimates using the treasury corporate tax model of effective tax rates for a variety of industry groupings our estimates suggest that the after tax cost of debt varies widely across industries the magnitude of the effective tax advantage to debt finance has important implications for corporate financial behavior one issue which has been examined extensively in the corporate finance literature is whether the value of the firm is affected by the firm s leverage ratio in a recent contribution deangelo and masulis 3 have shown that financing decisions can affect the value of the firm if the effective tax advantage to debt finance varies among firms or is reduced by the presence of nondebt tax shields such as investment tax credits and depreciation deductions the effective tax advantage to debt is also an important determinant of leverage related costs gordon and malkiel 5 have recently used the statutory tax rate to estimate expected bankruptcy costs induced by the corporate tax when the firm is assumed to balance the marginal tax advantage to debt with marginal expected bankruptcy costs if however the effective tax rate for interest deductions falls short of the statutory rate the magnitude of these costs may be overstated this paper presents detailed estimates of the marginal effective tax advantage to debt finance our estimates based on data in the treasury 1978 corporate master statistical file and on simulations done with the treasury corporate tax model quantify the impact of increasing interest deductions without changing other items on the corporation s income statement 1 we simulate the impact of a change in a firm s capital structure holding its investment and production decisions constant this is an appropriate procedure for estimating the marginal

the response of expenditures to anticipated income changes panel data estimates standard models of intertemporal allocation predict that the time path of expenditures should be independent of the time path of income recently two papers parker 1999 and souleles 1999 have suggested that u s households have a high marginal propensity to spend within year anticipated income changes we use an expenditure survey panel from spain to re examine this issue we exploit two important features of the spanish data first we have quarterly panel data that follows households for more than four quarters second we use the fact that workers are exogenously sorted into one of two payment schemes some receive the same amount each month of the year and others receive an extra payment in june and december the extra payment is large and predictable we examine the detailed pattern of expenditures over the year to see whether they differ between the two groups we fail to find even weak differences we complement this with a conventional euler equation analysis of excess sensitivity our predicting equation for quarterly earnings growth is much better than usual and is likely to give a powerful test of the hypothesis that predictable changes in income do not lead to changes in expenditure patterns the results of this analysis confirm the graphical analysis we find no evidence of excess sensitivity we conclude that households in normal times do smooth consumption over the year we suggest a reconciliation of our results with those of parker and souleles

the structure and incentive effects of corporate tax liabilities this paper describes situations in which tax liabilities assume the form of a negative position in a call option this structure motivates an examination of the investment decisions of taxed corporations in the presence of risk it is shown that the structure of the tax liability creates an incentive to underinvest in more risky projects and an incentive for conglomerate merger these effects are then evaluated in the presence of conflicts of interest between stockholders and bondholders and under alternative assumptions about the tax code and about the timing of investment and financing decisions this paper makes an observation regarding the functional form assumed by the tax liabilities of corporations with potentially redundant deductions and evaluates its consequences for investment incentives interest and other deductions against taxable income can be taken for the most part only to the extent of that income in a single period model this gives the net tax liability a familiar structure it can be viewed as a call option where the exercise price on the call is the allowable deductions the tax paying entity holds a positive position in the assets which generate the taxable income and a negative position in a call option on those assets the analogy between options and the structure of tax liabilities calls attention to some interesting incentive effects concerning risk using their model of option valuation black and scholes 5 showed that the value of an option is increasing in the variance of the asset it is written on other authors have generalized this result and studied its implications for corporate financing see jagannathan 16 jensen and meckling 17 and green 15 the importance of the risk attributes of the underlying asset in option valuation suggests that taxation may have important incentive consequences for investment decisions involving risk it has been recognized in the public economics literature for some time that asymmetries in the tax schedule can affect risk taking behavior early papers by mossin 20 and stiglitz 25 studied individual portfolio decisions over a riskless and a risky asset our analysis differs from these in a number of respects the most important of these is our use of market valuation rather than expected utility in the decision maker s objective function this is surely a more appropri

tentative governing of fuel cell innovation in a dynamic network of expectations abstract expectations and visions are known to be forceful elements in the governance of emerging innovations however visions and expectations are prone to change thus creating challenges for strategy and policy processes actors have to deal with the dynamics of expectations either ex post when expectations have changed or ex ante for instance by taking possible future changes into account in the design of policy measures this article follows the dynamics of fuel cell expectations in the german policy discourse 1994 2011 firstly we study how fuel cell expectations were discursively related to a wider network of expectations regarding developments in the context of fuel cells secondly we examine whether and how policy measures referred to these expectations and how policy dealt with the dynamic evolution of expectations we show that fuel cell expectations alone were not sufficient to trigger substantial policy support only once they linked up with visions and expectations about the future energy system and further context developments were supportive policy measures initiated furthermore although we observed dedicated and successful efforts to stabilize policy support for fuel cells pre empting possible changes in expectations governance still had to adapt to changes in the network of expectations in particular the rise in expectations for battery electric vehicles

do consumers react to anticipated income changes evidence from the alaska permanent fund a central implication of the life cycle permanentincome hypothesis lc pih is that consumers should not respond to predictable changes in their income to test this hypothesis a number of recent papers have exploited natural experiments to identify anticipated income changes in particular recent work by parker 1999 uses the change in after tax income due to the cap on earnings subject to the social security tax and a related paper by souleles 1999 examines the response of consumption to income tax refunds surprisingly parker and souleles find that even when income is expected to change within the year expenditure is excessively sensitive to the timing of the income change while their results can be interpreted as evidence that our canonical model of consumption is inadequate an alternative explanation is that the anticipated income changes they exploit are small and irregular and that households will not bother to change their consumption paths when the computational costs involved are large relative to the utility gains in support of this interpretation browning and collado 2001 find that the seasonal consumption patterns of spanish households that work in sectors that provide regular bonus payments do not differ from those of households that do not receive bonus payments this paper adds to this evidence by exploiting a natural experiment provided by annual payments from the state of alaska s permanent fund to every resident in the state of alaska that should yield an unusually powerful test of the lc pih these payments are large and clearly anticipated by alaskan residents using the variation in the size of the payments over time and in the amount received by families of different sizes to identify the response of consumption to payments from the permanent fund i find no evidence that the consumption of alaskan households reacts to these payments in addition i find no evidence that the seasonal pattern of consumption in alaska differs from that in the other 49 states or that households in alaska are subject to fewer liquidity constraints engage in less buffer stock saving or spend a smaller fraction of their income on semidurable goods than households in the rest of the united states however although households in alaska do not overreact to payments from the permanent fund i find that the consumption of the very same households is excessively sensitive to their income tax refunds this evidence suggest that households will take anticipated income changes into account in their consumption decisions when the income changes are large regular and easy to predict but will not do so when they are small and irregular the paper proceeds as follows the next section of the paper presents details on the department of economics princeton university princeton nj 08544 and national bureau of economic research e mail chsieh princeton edu i am very grateful to the bureau of labor statistics bls for providing access to the data from the consumer expenditure survey and to its staff particularly steven henderson walter vandeheide and wolf weber for their generous assistance during my visits to the bls i also thank nanci jones for providing data and patiently answering questions on the operation of the alaska permanent fund anne case angus deaton jonathan parker and two referees provided useful comments the views expressed in this paper are personal and should not be attributed to the bls 1 i refer to the certainty equivalent version of the lc pih or one in which the expected variance of consumption is constant as is well known without these assumptions the lc pih only implies smoothing of marginal utility not necessarily of consumption 2 see christina h paxson 1992 john shea 1995 jonathan a parker 1999 nicholas s souleles 1999 martin browning and m dolores collado 2001 also see ronald a bodkin 1959 for an early example of the use of a natural experiment to test for excess sensitivity for comprehensive reviews of the large literature on empirical tests of the lc pih see angus deaton 1992 browning and annamaria lusardi 1996 and browning and thomas f crossley 2001 3 in 1998 for example the permanent fund paid 1 541 to every resident of the state of alaska

innovation and policy for bioenergy in the uk a co evolutionary perspective de laurentis c innovation and policy for bioenergy in the uk a co evolutionary perspective regional studies this paper analyses the role of niche innovation and regime interaction in the field of renewable energy in the uk adopting a co evolutionary approach and a dynamic multilevel perspective on system innovation it investigates niches development in the uk in the field of bioenergy and its interaction with the current energy regime contributing to the debate about spatial scales at which sustainability transitions can be conceptualized the paper utilizes the case of niche development in the region of wales to provide supporting evidence of the importance of context specific social and political relations that may foster or hinder regime transformation

leasing taxes and the cost of capital abstract a model of firm financial and investment behaviour when there is a possibility of tax exhaustion is used to analyse the incentives for firms to act as lessees or lessors and the determination of the equilibrium rental rate in the leasing market a number of results emerge which are relevant for public policy it is shown that i leasing may diminish aggregate investment by comparison with the situation when it does not occur ii rents are likely to be earned on leasing activities and iii a purely tax induced positive relationship exists between aggregate investment and corporate profits

in the mood to consume effect of sunshine on credit card spending abstract using a large representative sample of high frequency credit card transactions in the united states this paper examines the causal effect of sunshine induced mood on contemporaneous household credit card spending we document a 0 3 percent increase in credit card spending in response to a one unit increase in the same day local abnormal sunshine the spending response is stronger for consumers with higher credit card debt lower fico score and shorter tenure with the bank the effect manifests in long term durable goods spending and is not driven by other weather conditions complementarity between sunshine and consumption or intentional choice of consumption time we document similar responses of spending on seasonal and non seasonal goods and during times with high and low sunshine levels finally the sunshine effect occurs among consumers with various characteristics

corporation tax asymmetries and investment evidence from uk panel data theoretical work has emphasised the potentially powerful impact of corporation tax asymmetries on investment behaviour but empirical work has mainly been confined to the measurement of effective tax rates this paper uses panel data from 597 u k companies to ask are tax asymmetries important to understanding observed investment behaviour an optimising investment model is developed and estimated both as a q equation and a euler equation in which the cost of capital appears careful modelling of asymmetries does not noticeably improve the empirical performance of these equations possible explanations are discussed

innovation processes in large technical systems market liberalization as a driver for radical change abstract electricity supply is a large technical system which exhibits strong path dependencies and high barriers for radical innovations recent market liberalization however has initiated a fundamental restructuring the paper analyzes how liberalization has altered innovation processes in the field of electricity supply we examine three radical innovations under monopoly conditions and contrast the findings with the results from a survey on the innovation behavior of electric utilities in liberalized markets we argue that the selection environment for innovations has changed in various respects in our sample new options open to innovation activities have emerged at the level of the firm and utility strategies turn out to be more heterogeneous this may be interpreted as an increase in the variety of search processes which may lead to a mid term decrease of path dependencies

addressing barriers in the water recycling innovation system to reach water security in arid countries abstract as arid regions face increasing pressures on their water resources the challenge of securing an adequate supply of good quality water to meet growing demands calls for innovative approaches that involve a diversification of water supply options and improved management of wastewater water recycling is a disruptive innovation that can help to achieve this goal in arid countries if the appropriate technical and institutional barriers are broken down within the water innovation literature key questions remain as to the nature of the process and of the temporal dynamics of a shift towards decentralized wastewater infrastructure this study offers insights into these mechanics using the framework for analyzing a multi level innovation system famis a cross sectoral model that draws on the theories of technological innovation systems system dynamics transitions of socio technical regimes and evolutionary theories of technology cases from three water scarce countries with distinct political economies australia the united arab emirates u a e and jordan were used to document the dynamics of innovation in the water recycling system and identify policy solutions despite important contextual differences in the three cases examined actors and institutions have dynamically interacted to create a small niche where water recycling has emerged as a viable technology yet the application of the famis model revealed that the dominant regime of water management has not been fundamentally altered due to blockages mainly at two stages of the famis innovation lifecycle the selection and adoption stages we identified cross geographical socio technical and environmental characteristics and common mechanisms that strongly influence the evolution of water recycling technology through the innovation system we find that the water recycling technology evolves into the later stages of the innovation system in australia with the chokepoint occurring most importantly within the sophisticated but fragmented institutions that regulate water recycling in the u a e while agricultural reuse is widespread to a larger extent than in australia major barriers occur earlier in the system leaving mainly the water recycling technologies in the early stages of the system where policy induced path dependency block most selection mechanisms with a wider infrastructural and institutional gap jordan may actually face less stringent barriers to water recycling developments throughout all stages of the innovation system namely influenced by international donors policy recommendations derived from this work to address barriers at the selection and adoption stages include favoring a coordinated institutional long term vision and planning to overcome path dependence enhancing social acceptance and adequate implementation of laws and regulations and supporting data acquisition and model developments to build a stronger business case for water recycling

conceptualising multi regime interactions the role of the agriculture sector in renewable energy transitions abstract the agriculture sector plays an important role in renewable energy transitions owing to its historical involvement in managing key resources particularly land and biomass we develop the multi level perspective in relation to these emergent transition processes conceptualising transitions towards renewable electricity production as examples of multi regime interaction between national level agriculture and electricity regimes we focus particularly on the role of niche anchoring into multiple regimes as the mechanism through which multi regime interaction occurs utilising case studies in germany the czech republic and the united kingdom analysis suggests the birth of a new fiat regime oriented towards renewable electricity production we suggest that fiat regimes which are heavily dependent on policy supports are often multifunctional in nature in addition we argue that agriculture s inherent connection to land demonstrates one of the specific characteristics of fiat regimes fiat regimes are constructed largely in response to policy efforts to produce or protect public goods such as natural resources as opposed to market regimes based on technological developments findings demonstrate support for the special case of the agriculture sector in transition processes high degrees of policy involvement led to windows of opportunity created largely in response to national and international policy agendas and the multiple functions of agriculture were reflected in competition between agriculture and electricity sectors over natural resource access as renewable energy currently represents a secondary transition in the agriculture sector we suggest that further attention needs to be paid to the impact of fiat regime policies on secondary transition processes

smart grids and the transformation of the electricity sector ict firms as potential catalysts for sectoral change abstract the sustainability challenges associated with increasing demand and generation of electricity require a far reaching transformation of the energy system smart grid technologies are expected to play a major role in such sectoral transformation while a growing body of literature is concerned with the dynamics and particularities of sectoral transformation most contributions have focused on exogenous shocks or new technological developments as drivers of change this paper complements the existing perspectives by exploring the role of actors as catalysts for transformation within the field of smart grid we study the transformative influence of ict firms on the energy sector in europe more specifically we analyze actor participation in 450 european smart grid projects between 2000 and 2011 as well as acquisitions in the field we find that incumbent firms from the ict sector have gained influence and drive transformation through the creation of variety in terms of technology business models and value chains as a strategic reaction electricity sector incumbents have recently acquired many start ups specialized in ict technology and thus expanded their competence base we conclude that entrants from another sector can be important catalysts for sectoral transformation and should be analyzed more systematically in transition studies

the dynamic effects of tax law asymmetries under the laws of most countries a distinction is made between gains and losses by businesses losses that must be carried forward are subjept to two penalties a loss of interest and expiration previous examinations have focused on the higher expected tax payments such a tax system without full loss offset imposes on risky projects this paper presents a dynamic analysis of the impact of taxation on investment when gains and losses are treated asymmetrically the results demonstrate how firm characteristics and the timing of taxes can influence behaviour under current u s tax law a distinction is made between gains and losses by businesses for corporations gains are taxed at what is essentially a flat rate of 46 while losses do not necessarily qualify for a refund at the same rate to obtain an immediate refund the taxpayer must have had taxable income during the three previous years in excess of the current loss any losses that cannot be carried back in this fashion must be carried forward subject to two implicit penalties such loss carryforwards earn no interest and they expire after fifteen years similar provisions apply in other countries hence businesses investing in risky projects for which the probability of having to carry losses forward is positive can expect to pay higher taxes than they would under a system with full loss offset i e the immediate refund of taxes for losses incurred many corporations

taxation and the cost of capital the uk experience since the 1960s the uk has witnessed a series of reforms to its corporation tax system these include the creation of corporation tax as an independent tax in 1965 the gradual introduction of generous capital allowances in the early 1970s the introduction of the partial imputation system in 1973 and stock relief in 1975 and the 1984 reforms which reduced the tax rate and capital allowances and abolished stock relief a number of these reforms were designed with the specific intention of influencing company decisions regarding investment and finance through the real cost of capital

corporation tax finance and the cost of capital this paper examines the influence of corporate tax exhaustion on the firm s financial and investment decisions a dynamic programming model is used to establish effective marginal tax rates in the presence of a tax system that permits the carry forward of losses to future periods the paper demonstrates that internal optimal financial structures may result which do not require the imposition of external constraints the cost of capital is highly sensitive to the current taxable earnings of the firm and the implications of this for such tax transfer activities as leasing are discussed

the hygienic transition from cesspools to sewer systems 1840 1930 the dynamics of regime transformation this article addresses the topic of transition and system change and proposes endogenous regime transformation as alternative transition path to technological substitution using sociological and institutional insights the dynamics of regime transformation are conceptualised two characteristics are pressure from outsider groups and adjustments in cognitions norms and formal rules enacted by regime insiders the transformation perspective is illustrated with a historical case study the hygienic transition from cesspools to integrated sewer systems in the netherlands the case study is used to make additions to the transformation perspective particularly with regard to tactical and strategic games

deep transitions emergence acceleration stabilization and directionality abstract industrial society has not only led to high levels of wealth and welfare in the western world but also to increasing global ecological degradation and social inequality the socio technical systems that underlay contemporary societies have substantially contributed to these outcomes this paper proposes that these socio technical systems are an expression of a limited number of meta rules that for the past 250 years have driven innovation and hence system evolution in a particular direction thereby constituting the first deep transition meeting the cumulative social and ecological consequences of the overall direction of the first deep transition would require a radical change not only in socio technical systems but also in the meta rules driving their evolution the second deep transition this paper develops a new theoretical framework that aims to explain the emergence acceleration stabilization and directionality of deep transitions it does so through the synthesis of two literatures that have attempted to explain large scale and long term socio technical change the multi level perspective mlp on socio technical transitions and techno economic paradigm tep framework

lease valuation when taxable earnings are a scarce resource in this paper we examine leasing as a tax arbitrage instrument analysis of a sample of uk leases presented in this paper suggests that lessors earn large positive npvs our theoretical model seeks to explain these positive npvs in terms of a market price for a scarce resource that we identify as scarce taxable earnings using these prices the model permits a lessor to determine whether the profitability of a proposed set of lease contracts can be improved by writing e different set of contracts that makes better use of the lessor s taxable earnings there may be two reasons why an initial portfolio of contracts may be suboptimal either there may be clienteles or the leasing market may be inefficient subsequently we discuss reasons why the leasing market may be characterized by clienteles and using two different samples of leases we test whether the leasing market is segmented and efficient in this paper we examine leasing as a tax arbitrage instrument with asymmetrical tax positions between lessors and lessees there will be positive net present values npvs to lease transactions see myers dill and bautista 21 analysis of a sample of united kingdom uk leases presented in this paper suggests that lessors earn large positive npvs our theoretical model seeks to explain these positive npvs in terms of a market price for a scarce resource that we identify as scarce taxable earnings there are two implications of our model one for financial intermediaries that act as lessors and the other for financial economists interested in the leasing market the model permits a lessor to determine whether the profitability of a proposed set of lease contracts can be improved upon by writing a different set of contracts that makes better use of the lessor s taxable earnings there may be two reasons why an initial portfolio of contracts that a lessor is about to write may be suboptimal either there may be clienteles because the leasing market

multi regime dynamics in the analysis of sectoral transformation potentials evidence from german utility sectors abstract network bound infrastructure systems as electricity gas water and telecommunications are currently undergoing transformations on various levels and dimensions liberalization technological innovations and socio cultural dynamics are part of this for analyzing these ongoing transformation dynamics as well as exploring future developments of utility systems a theoretical concept is necessary which spans production consumption and governance different levels and also different sectors this paper argues that the multi level perspective is a fruitful starting point allowing the identification of interrelated transformation dynamics in production consumption and governance but that multi regime dynamics need more emphasis particularly in a future oriented analysis
