david pearce and the economic valuation of biodiversity david pearce was a pioneer in the economic valuation of biodiversity his work powerfully influenced both later economists who worked in the field and natural scientists and practitioners who gained and appreciation of the importance of economics to their efforts pearce often applied the paradigm of demonstration followed by appropriation the values of biodiversity must first be demonstrated to those who make decisions concerning its survival and then appropriated by them the later step will be possible when market and policy failures are rectified so as to allow the realization of conservation values while pearce wrote extensively on these themes he was also acutely aware of the limitations of the paradigm rosy projections of values that could not be realized and appropriated would be of little practical use and pearce often cautioned against excesses of optimism yet he also clearly believed that there are compelling if not always easily demonstrated reasons for conservation i argue in this paper that pearce s seminal work on the valuation of biodiversity cannot be understood without some appreciation of his philosophical perspective pearce would have described himself as a pragmatist however his pragmatism was grounded in the belief that it is both expedient and ethical to recognize that communities in some of the poorest corners of the world will only conserve biodiversity if they are justly compensated for the sacrifices they must make to do so

debt and financial expectations an individual and household level analysis in this article we show that optimistic financial expectations impact positively on both the quantity of debt and the growth in debt at the individual and household levels our theoretical model shows that this association is predicted under a variety of plausible scenarios in the empirical analysis we explore the determinants of debt and of growth in debt using british data we find convincing support for our theoretical priors and show that it is optimistic financial expectations per se that are important in influencing debt rather than the accuracy of individuals predictions regarding their future financial situation jel d18 d84 d91

nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

progress along the path evolving issues in the measurement of genuine saving more than 10 years since a practical linkage between sustainable development and a measure of national wealth expanded to include natural and environmental resources was first posited the empirical estimation of adjusted net savings dubbed genuine saving has evolved considerably in this paper we take stock of both progress achieved and the challenges that remain we begin by recalling the key points made in pearce and atkinson 1993 ecol econ 8 103 which presented the first cross country estimates of savings rates adjusted to reflect depletion and degradation of the environment we then briefly summarise the evolution of the theoretical argument linking savings and sustainability however the main focus of this paper is an aspect that concerned david pearce greatly namely the evolution of the measurement of genuine savings we identify and consider the empirical evidence with regard to two particular measurement issues the valuation of exhaustible resources and environmental degradation common to the both issues are concerns about measuring changes in national wealth in real world economies

a life cycle consumption model with liquidity constraints theory and empirical results a structural consumption model incorporating endogenous liquidity constraints is fit to a cross section of 798 u s families liquidity constrained families are estimated to constitute 19 4 percent of the population sampled a group that accounts for 16 7 percent of consumption in the population sampled in sample simulations of the model suggest that a temporary tax has three to four times more impact on aggregate consumption than it would if liquidity constraints were not in effect copyright 1987 by the econometric society

borrowing constraints and credit demand in a developing economy summary this paper investigates the determinants of credit demand in the presence of borrowing constraints in a developing economy we model the determinants of observed debt for chilean households while accounting for selection bias and the endogeneity of their income and specific household assets using a novel chilean dataset we estimate the relationship between household characteristics and consumer and mortgage debt we find substantial differences in the nature of these relationships across the types of debt for example we find that the income elasticity for consumer debt is greater than 1 whereas for mortgage debt it is not the results suggest the increased availability of credit combined with the aging of the chilean population is likely to drastically change the distribution and level of chilean debt these findings are particularly relevant for other developing economies currently experiencing rapid income and debt growth copyright 2015 john wiley sons ltd

constrained after college student loans and early career occupational choices abstract in the early 2000s a highly selective university introduced a no loans policy under which the loan component of financial aid awards was replaced with grants we use this natural experiment to identify the causal effect of student debt on employment outcomes in the standard life cycle model young people make optimal educational investment decisions if they are able to finance these investments by borrowing against future earnings the presence of debt has only income effects on investment decisions we find that debt causes graduates to choose substantially higher salary jobs and reduces the probability that students choose low paid public interest jobs we also find some evidence that debt affects students academic decisions during college our estimates suggest that recent college graduates are not life cycle agents two potential explanations are that young workers are credit constrained or that they are averse to holding debt we find suggestive evidence that debt reduces students donations to the institution in the years after they graduate and increases the likelihood that a graduate will default on a pledge made during her senior year we argue this result is more likely consistent with credit constraints than with debt aversion

overcoming information asymmetries in low income lending lessons from the working wheels program without access to transportation the welfare to work transition is nearly impossible yet little is known about the effectiveness of programs designed to improve credit access since 1998 vermont s tanf funds have provided automobile loans through the working wheels program we use microlevel data from this program to explore how to cost effectively provide loans to clients who cannot obtain affordable loans elsewhere our results verify the importance of relationship lending particularly among those without documented credit histories in the presence of information asymmetries about credit history our results justify the increased trust placed in clients with whom the bank has a stronger relationship such clients ceteris paribus are less likely to default we conclude that in the current climate of welfare reform policymakers should consider programs that encourage welfare recipients to establish and maintain relationships with financial institutions in order to facilitate access to credit and minimize the risk of default

endogenous monetary policy with unobserved potential output this paper characterizes monetary policy when policymakers are uncertain about the extent to which fluctuations in output and inflation are due to changes in potential output or to cyclical demand and cost shocks our results suggest an explanation for the inflation of the 1970s and the price stability of the 1990s it is shown that 1 policy is likely to be excessively loose for some time when there is a large decrease in potential output in comparison to a full information benchmark 2 retrospective policy errors and errors in forecasting potential output and the output gap are generally serially correlated 3 the increase in the fed s conservativeness between the 1970s and the 1990s implies that the information problem had greater consequences in the former period

robust monetary policy optimal delegation and misspecified potential output abstract central banks face uncertainty about potential output we model optimal monetary policy under discretion in a situation in which the central bank adopts a min max approach to policy the case for appointing a conservative central banker who puts a larger weight on inflation stabilization becomes stronger as the central bank s concern about misspecifications increases

beyond implicit prices recovering theoretically consistent and transferable values for noise avoidance from a hedonic property price model using a two stage hedonic pricing methodology we estimate a system of structural demand equations for different sources of transport related noise in the first stage we identify market segments using model based clustering techniques and estimate separate hedonic price functions hpfs for each segment in so doing we show how a semiparametric spatial smoothing estimator outperforms other standard specifications of the hpf in the second stage we control for non linearity of the budget constraint and identify demand relationships using techniques that account for problems of endogeneity and censoring of the dependent variable our estimated demand functions provide welfare estimates for peace and quiet that we believe to be the first derived from property market data in a theoretically consistent manner

on a clear day you might see an environmental kuznets curve we shed some new light on the environmental kuznets curve ekc and show how it can be viewed as a particular form of equilibrium relationship where technology and preference parameters determine the shape of the curve in contrast to most of the literature on the ekc we estimate a theoretically consistent model on long run data swedish sulfur emission covering the period 1900 2002 furthermore we test and date structural change the model suggests four regimes 1900 1918 1919 1933 1934 1967 and 1968 2002 generating four rather different patterns for pollution over time the policy conclusions are consonant with pearce s general view about the ekc there is no theoretical presumption that it has an inverted u shape nor should any country try to grow out of the environmental problems without analyzing the benefits and costs of so doing

sovereign stress and smes access to finance evidence from the ecb s safe survey abstract we study the effect of sovereign stress on smes capital structure using restricted access data from the european central bank we find that during the sovereign debt crisis and controlling for borrowers quality firms in stressed countries became more likely to be denied credit to be credit rationed and to face higher loan rates less creditworthy firms were not more likely to become credit constrained suggesting no flight to quality in lending we also find that in order to make up for the decline in bank credit firms in stressed countries began relying considerably more on retained earnings and government subsidies

releasing constraints to growth or pushing on a string policies and performance of mexican micro firms abstract using firm level data from mexico this paper investigates the firm characteristics associated with participation in credit markets access to training tax payments and membership in business associations we find that firms which participate in these institutions exhibit significantly higher profits moreover firms that borrow from formal or informal sources and those that pay taxes are significantly more likely to stay in business but firms that received credit exhibit lower rates of income growth these results persist when firm characteristics that are arguably correlated with unobserved entrepreneurial ability are controlled for our findings suggest that the significant within country differences in firm productivity observed in developing economies are due in part to market and government failures that limit the ability of micro firms to reach their optimal sizes

the green revolution development of labor markets and poverty reduction in the rural philippines 1985 2004 using a long term household panel data set collected in three rural villages in the philippines in 1985 and 2004 this article explores how the green revolution and development of the labor markets have affected household income and poverty situation the initial rise in income associated with the green revolution and a stronger credit access has enabled the households to allocate funds for investing in children s schooling with the increased integration of the rural with the urban labor market these children are able to explore labor opportunities in the nonfarm sector that resulted in a decline in poverty by about one half the landless households who are less educated benefited too from the expansion of the nonfarm labor market because of the rise in rural wages associated with the rise in demand for the unskilled labor which is by far their most important asset

personal bankruptcy and credit supply and demand this paper examines how personal bankruptcy and bankruptcy exemptions affect the supply and demand for credit while generous state level bankruptcy exemptions are probably viewed by most policy makers as benefiting less well off borrowers our results using data from the 1983 survey of consumer finances suggest that they increase the amount of credit held by high asset households and reduce the availability and amount of credit to low asset households conditioning on observable characteristics thus bankruptcy exemptions redistribute credit toward borrowers with high assets interest rates on automobile loans for low asset households also appear to be higher in high exemption states

do firms get the financing they want measuring credit rationing experienced by small businesses in the u s this paper measures the extent to which small businesses in the united states in the late 1980s were able to access the external credit finance they desired we argue that a comprehensive definition of credit rationing must account for both a creditworthy firms that apply for and are denied financing and b creditworthy firms that decide not to apply for desired external financing given expectations about how long it may take to obtain financing and the evolution of investment opportunities

credit constraints and productivity in peruvian agriculture this article evaluates the performance of a rural credit market in peru we develop a model that shows that collateral requirements imposed by lenders in response to asymmetric information can lead not just to quantity rationing but also to transaction cost rationing and risk rationing just like quantity rationing these two additional forms of nonprice rationing adversely affect farm resource allocation and productivity we test the insights of the model using a panel data set from northern peru we estimate the returns to productive endowments for constrained and unconstrained households using a switching regression model we find that consistent with the theory productivity is independent of endowments for unconstrained households but is tightly linked to endowments for constrained households we estimate that credit constraints lower the value of agricultural output in the study region by 26

excess sensitivity of consumption to current income liquidity constraints or myopia this paper asks whether the empirical rejection of the rational expectations permanent income hypothesis occurs because agents are myopic in the sense that the marginal propensity to consume out of transitory income is non zero or because some agents face liquidity constraints the finding that the estimate of the mpc out of transitory income is dramatically affected in both magnitude and statistical significance by the inclusion of a proxy for liquidity constraints suggests that liquidity constraints are an important part of the explanation of the observed excess sensitivity of consumption to current income la sensibilite excessive de la consommation au revenu courant contraintes sur la liquidite ou myopie ce memoire examine la question a savoir pourquoi l hypothese du revenu permanent avec anticipations rationnelles n est pas v6rifiee empiriquement est ce parce que les agents economiques sont myopes i e que leur propension marginale a consommer a partir de leur revenu transitoire n est pas nulle ou bien est ce que certains agents economiques font face a des contraintes sur leur liquidite le fait que l estimation de la propension marginale a consommer le revenue transitoire est affectee par l inclusion d une variable qui tente de capturer l importance des contraintes sur la liquidit6 tant dans l 6valuation de sa taille que dans sa signification statistique suggere que ces contraintes jouent un role important dans l explication de cette sensibilite excessive qu on observe de la consommation aux changements dans le niveau de revenu courant almost all the recent empirical tests of the rational expectations permanent income hypothesis re pih have rejected the hypothesis using a rich variety of data sets and estimation methods the empirical work indicates that the failure of the re pih is significant both statistically and quantitatively the null hypothesis in this empirical literature typically consists of the joint hypothesis that 1 agents expectations are formed rationally 2 desired consumption is determined by permanent income and 3 capital markets are perfect in the sense that agents can lend or borrow against 1 studies rejecting the re pih include blinder 1981 flavin 1981 hall and mishkin 1982 hayashi 1982 and sargent 1978 in his original paper hall 1978 did not reject the re pih decisively however flavin 1981 showed that with a minor alteration in the specification of the alternative hypothesis the re pih could be rejected using hall s test and data set bernanke 1981 studying panel data on automobile expenditures did not find evidence against the hypothesis for an extensive survey of the empirical literature on the rational expectations permanent income hypothesis see king 1983 canadian journal of economics revue canadienne d economique xviii no 1 february fevrier 1985 printed in canada imprime au canada 0008 4085 85 117 36 1 50 canadian economics association this content downloaded from 157 55 39 17 on wed 31 aug 2016 05 08 58 utc all use subject to http about jstor org terms

the permanent income hypothesis estimation and testing by instrumental variables the permanent income hypothesis with rational expectation is restated estimated and tested by an instrumental variables technique on the postwar u s aggregate time series data the hypothesis is accepted on a consumption series which includes service flows from consumer durables if the consumption series is the one in the national income and product accounts the hypothesis is decisively rejected an explanation is suggested to reconcile the conflicting test results

subprime consumer credit demand evidence from a lender s pricing experiment using a unique panel data set from a u k credit card company we analyze the interest rate sensitivity of subprime credit card borrowers in addition to all individual transactions and loan terms we have access to details of a randomized interest rate experiment conducted by the lender on existing inframarginal loans for the whole sample we estimate a statistically significant 3 4 reduction in monthly credit demand in response to a five percentage point increase in interest rates this aggregate response is small but it masks very interesting heterogeneity in the sample we find that only low risk borrowers who fully utilize their credit cards lower their credit demand significantly when faced with an increase in interest rates we also document that a five percentage point increase in interest rates generates significant additional revenue for the lender without inducing delinquency over a short horizon 2013 the author

who is credit constrained in the u s economy an important assumption of the life cycle model of consumption is the postulate of perfect capital markets this hypothesis has recently been challenged by substantial empirical evidence hall and mishkin 1982 using the panel study of income dynamics estimate that 20 percent of united states families are liquidity constrained mariger 1986 derives a life cycle model with endogenous liquidity constraints and using a cross section estimates this fraction to be 19 4 percent hubbard and judd 1986 simulate a model with a constraint on net worth which shows that with reasonable assumptions about preferences 19 0 percent of united states consumers are liquidity constrained the emerging consensus points therefore to a fraction of approximately 20 percent of the population behaving in a manner that is inconsistent with the pure life cycle model in addition hayashi 1985 and zeldes 1989 investigate the correlation among consumption wealth and income for various population groups and infer that liquidity constraints are more important for younger families with low levels of wealth and saving the main limitation of these studies is that in their data sets constrained consumers are not observable and have to be identified via indirect evidence thus there is as yet little firm evidence about the characteristics of the consumers who are likely to be credit constrained this paper adopts an approach that differs from previous tests for liquidity constraints because it makes use of data where constrained consumers are observable and explicitly links their existence to credit market imperfections and personal characteristics the data drawn from the 1983 survey of consumer finances scf and described in section ii provide information on individuals whose request for credit has been rejected by financial intermediaries in section iii a model is developed in which consumers and lenders behavior jointly determines the probability that a consumer is rationed in the credit market this probability is then

intertemporal consumption durables and liquidity constraints a cohort analysis we provide a theoretical framework to analyse the response of life time maximizing consumers to intertemporal prices of non durable goods and durable goods when the borrowing limit depends on the market value of the stock of durables owned by the consumer we use pseudo panel data on purchases of non durables and durable goods cars and demographic characteristics from the uk family expenditure survey as well as estimates of the durable stock constructed using the uk national travel survey to estimate the equations derived in the first part of the paper we evaluate the shadow prices of these restrictions which were significantly positive for younger consumers in the mid seventies and immediately prior to the 1982 financial liberalisation

subprime borrowers securitization and the transmission of business cycles a growing literature i e jaffee lynch richardson and van nieuwerburgh 2009 acharya and schnabl 2009 argues that securitization improves financial stability if the securitized assets are held by capital market participants rather than financial intermediaries i construct a quantitative macroeconomic model with a novel specification for mortgage backed securities mbs to evaluate this claim my findings suggest that the existence of the securitization market stabilizes the economy under the condition that financial intermediaries do not engage in the acquisition of securitized assets in the presence of large negative housing preference shocks the drop in output in the first year after the shock is halved if subprime mbs are purchased by non financial agents rather than held by banks less

the effect of liquidity constraints on consumption a cross sectional analysis this paper examines the effect of liquidity constraints on consumption expenditures using a single year cross section data set a reduced form equation for consumption is estimated on high saving households by the tobit procedure to account for the selectivity bias since high saving households are not likely to be liquidity constrained the estimated equation is an appropriate description of how desired consumption that would be forthcoming without liquidity constraints is related to the variables available in the cross section data when the reduced form equation is used to predict desired consumption the gap between desired consumption and measured consumption is most evident for young households

the reaction of consumer spending and debt to tax rebates evidence from consumer credit data we use a new panel data set of credit card accounts to analyze how consumers responded to the 2001 federal income tax rebates we estimate the monthly response of credit card payments spending and debt exploiting the unique randomized timing of the rebate disbursement we find that on average consumers initially saved some of the rebate by increasing their credit card payments and thereby paying down debt but soon afterward their spending increased counter to the permanent income model spending rose most for consumers who were initially most likely to be liquidity constrained whereas debt declined most so saving rose most for unconstrained consumers

homeownership in the 1980s and 1990s aggregate trends and racial gaps abstract housing policy under the clinton and bush administrations has sought to boost homeownership while also narrowing racial gaps in owner occupancy rates against that backdrop homeownership rose sharply in the 1990s but white minority gaps remain in excess of 25 percentage points we analyze these patterns using data from the 1983 to 2001 survey of consumer finances results indicate that household characteristics explain most of the increase in homeownership and roughly two thirds of the white minority homeownership gap credit barriers account for no more than 5 percentage points of the remaining gap this suggests that policy makers will need to look beyond innovations in mortgage finance if their goal is to further expand homeownership

money credit constraints and economic activity when government expenditures exceed current tax revenues the resulting deficit must be financed either by issuing bonds which imply obligations to levy future taxes or by creating high powered money the choice between money and bonds is often thought to be of great moment for both real and nominal variables that is monetary policy matters there is by now a wide empirical consensus that monetary policy has effects on real variables like output and employment but there is far less agreement about why this is so the purpose of this paper is to take issue with some currently fashionable views of why money has real effects and to suggest a new theory or rather resurrect an old one the loanable funds theory and give it new improved microfoundations this abstract was borrowed from another version of this item

social security benefits consumption expenditure and the life cycle hypothesis this paper examines the impact of changes in social security benefits on aggregate consumption expenditure under the null hypothesis there should be no contemporaneous effect at the monthly frequency because increases in benefits have always been announced at least 6 weeks prior to payment the paper develops overwhelming evidence contrary to the null that benefits have affected aggregate spending the results have strong implications for several important issues including ricardian equivalence government policy irrelevance and the excess sensitivity of consumption to changes in income

climate change environmental and technology policies in a strategic context there are a number of features of climate change which make it one of the most challenging problems confronting policy makers and policy analysts in this paper we consider three such features i climate change is a global pollutant so there are strategic interactions between governments over climate policy ii cutting greenhouse gas emissions can have significant cost effects across a number of sectors of the economy raising concerns about the implications of climate change policy on competitive advantage iii the long time scales on which climate change operates means that an important dimension of climate change policy is policy towards r d to cut the costs of dealing with climate change in ulph and ulph 1996 ulph a ulph d 1996 in carraro c katsoulacos y xepapadeas a eds environmental policy and market structure kluwer dordrecht pp 181 208 we presented a model to analyse these issues but considered only environmental policies in this paper we extend that analysis to allow for both a richer set of policy instruments environmental and technology policies and a richer strategic context

the sensitivity of consumption to transitory income estimates from panel data on households we investigate the stochastic relation between income and consumption specifically consumption of food within a panel of about 2 000 households our major findings are 1 consumption responds much more strongly to permanent than to transitory movements of income 2 the response to transitory income is nonetheless clearly positive 3 a simple test independent of our model of consumption rejects a central implication of the pure life cycle permanent income hypothesis the observed covariation of income and consumption is compatible with pure life cycle permanent income behavior on the part of80 percent of families and simple proportionality of consumption and income among the remaining 20 percent as a general matter our findings support the view that families respond differently to different sources of income variations in particular temporary income tax policies have smaller effects on consumption than do other more permanent changes in income of the same magnitude this abstract was borrowed from another version of this item

further evidence of excess sensitivity of consumption nonseparability among goods and heterogeneity across households the standard theoretical framework for analysing households intertemporal decisions is the life cycle permanent income model among its implications testing the model allows to analyse the response of consumption to fiscal policy however the empirical literature with microdata has yielded mixed results this article examines the sensitivity of the results to the assumption of separability among goods and of homogeneity across households for that purpose we test a rational expectations permanent income model with household data drawn from the spanish family expenditure survey this survey contains detailed information on total expenditure and the income presents large exogenous quarterly changes due to an institutional feature the article shows that assuming separability among commodities biases the test against the model when separability is not imposed we show that the rejection of the model depends on heterogeneity across households in terms of their members being unemployed or not for those

fiscal policy with heterogeneous agents and incomplete markets i undertake a quantitative investigation into the short run effects of changes in the timing of proportional income taxes for model economies in which heterogeneous households face a borrowing constraint temporary tax changes are found to have large real effects in the benchmark model a temporary tax cut increases aggregate consumption on impact by around 29 cents for every dollar of tax revenue lost comparing the benchmark incomplete markets model to a complete markets economy income tax cuts provide a larger boost to consumption and a smaller investment stimulus when asset markets are incomplete copyright 2005 wiley blackwell

heterogeneous beliefs and housing market boom bust cycles abstract this paper presents a business cycle model capturing the stylized features of housing market boom bust cycles in developed countries the model implies that over optimism of mortgage borrowers generates housing market boom bust cycles if mortgage borrowers are credit constrained and savers do not share their optimism this result holds without price stickiness if price stickiness is introduced into the model then the model replicates a low policy interest rate during a housing boom as an endogenous reaction to a low inflation rate given a taylor rule thus monetary easing observed during housing booms are consistent with the presence of over optimism causing boom bust cycles

the latent demand for bank debt characterizing discouraged borrowers concerns that small firms encounter credit constraints are well entrenched in the literature despite widespread empirical evidence that a relatively small proportion of small firms have their loan applications rejected however many firms may be discouraged from applying for fear of rejection these businesses are the focus of this paper based on responses to a large scale postal survey of uk small and medium sized enterprises smes we find that twice as many businesses were discouraged from applying for a bank loan than had their loan request denied more particularly we observe a number of distinguishing characteristics of discouraged borrowers relative to applicants these include strategy sector prior entrepreneurial experience and banking relationships the implications of our findings for policy and future research are briefly discussed

ricardian equivalence in the presence of capital market imperfections abstract it is a common claim that ricardian equivalence fails if capital markets are imperfect the validity of this claim is examined for the case of informationally imperfect capital markets we present three alternative models of adverse selection and analyze the effects of debt finance in these models it is shown that a debt financed tax cut can lead to pareto improvement in some cases in the theoretically most preferable model however ricardian equivalence survives in spite of genuine imperfections in the capital market the results point to the importance of specifying the exact nature of imperfection

the response of household consumption to income tax refunds a central implication of the life cycle or permanent income theory is that consumption should not respond to predictable fluctuations in income tests of this implication have yielded mixed results especially on micro data angus deaton 1992 martin browning and annamaria lusardi 1996 in large part this might be due to the difficulties of isolating the predictable component of income at the micro level most tests proceed by instrumenting for income but since the available instruments are typically poor such tests might be prejudiced against finding significant excess sensitivity of consumption to income john shea 1995 also it is not clear how closely the resulting econometric predictions of income coincide with agents actual expectations of income to avoid these difficulties this paper examines the response of household consumption to a particular type of income that is both predictable and transitory income tax refunds since a refund depends on events in the previous calendar year it is predictable income as regards consumption in the year of its receipt consequently under the life cycle theory consumption should not increase on receipt of a refund 2 in addition to testing the canonical model of consumption this paper provides estimates interpretable as the marginal propensity to consume mpc out of refunds since federal tax refunds now amount to over 80 billion per year averaging well over 1 000 per refund these estimates are of interest in themselves more generally they bear on the impact of even preannounced and temporary changes in fiscal policy the paper begins by surveying related studies in section i section ii describes the data the consumer expenditure survey cex which of the leading u s micro data sets has the most comprehensive coverage of expenditure the empirical specification is set out in section hi section iv reports the results and section v concludes

the impact of mortgage interest rate subsidies on household borrowing abstract the responsiveness of household borrowing to changes in the interest rate is a crucial parameter for assessing public policies aimed at promoting saving we estimate the effect on household borrowing of a reform of a program that subsidized interest rates on mortgages signed by medium and low income households the reform established a ceiling in the price of the house that could be financed with the program first we use triple difference estimators exploiting the fact that the reform should affect most the borrowing behavior of eligible individuals living in high price areas and estimate that the elasticity of the probability getting a loan to the interest rate lies between 2 8 and 1 3 second we document that after the reform the distribution of loan sizes became more concentrated at the discontinuity point of the budget constraint of eligible individuals both findings are consistent with a negative response of household borrowing to increases in interest rates

harnessing the political economy of environmental policy david pearce s contribution to oecd during 34 years david pearce made major contribution to oecd work on environmental economic issues with a particular focus on cost benefit analysis economic instruments biodiversity and distributive issues this article provides a brief review of david pearce s contributions this work was particularly useful in enhancing the political economy of environmental policy which is at the core of oecd work

limits to cba in uk and european environmental policy retrospects and future prospects this paper reviews the contemporary debate and the now long standing role of cba in uk and european environmental policy appraisal epa and looks forward to possible future applications the position taken is that despite its limitations cba still has an important part to play in epa however with the increasingly contested nature of environmental and related public policies and outcomes its role will become less prescriptive and its findings more constrained by social justice and ethical imperatives future cba is more likely to continue to flourish as a component in a wider policy analysis and decision support system whatever decision support system is eventually adopted its value will be judged on how well it aids real policymakers operating iteratively in the non linear real world political economy

making a difference how environmental economists can influence the policy process a case study of david w pearce can environmental economists influence policy if so how this paper addresses these two questions using the late david pearce s career as a case study influence can be exercised but pearce s career shows that certain conditions must be met the first is desire he wanted to influence policy and directed a high proportion of his efforts to doing so he focused particular attention on the power centres of his time the oecd world bank european commission un uk government his influence was aided by his status and location as a professor in a prestige university ucl in a major global city london his messages were consistent and clear theory is important and can be used to frame most environmental challenges as regards both explanation and solution externalities can be valued assessing benefits and costs of options is important market signals taxes etc and incentives generally are powerful shapers of behaviour stock of capital human built natural is a key measure of sustainability he communicated simply and clearly in words and phrases that ministers for finance and journalists could understand all of the broadsheet newspapers in england financial times guardian independent telegraph times were grist to pearce s mill of advocacy for environmental economics he provided the blueprint books that could be read on a commute and summaries to the media that they could fit into a 1 000 word piece he didn t seek out but neither did he shirk controversy he worked with various interest groups and politicians but never to the point were he was co opted he initiated and directed the msc in environmental and resource economics that created an ever widening and influential pool of advocates for his ideas finally he achieved a prodigious academic output that ensures a sort of immortality and provided the intellectual ballast the enabled his policy influence

do we really care about biodiversity this paper addresses from an economic perspective the issue of global biodiversity conservation it challenges the perception that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock of natural capital despite the existence of a plethora of international agreements there still seems to be a global deficit of care surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation more light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for biodiversity conservation however actual expenditures are much lower than willingness to pay estimates recorded in the published literature using the criteria that the right amount of conservation effort is one where the marginal economic benefits from conservation just equal the marginal costs of conservation the paper explores the biodiversity conservation conundrum and concluded that on the available evidence the world does not care too much about this natural capital stock and bequests to future generations

the permanent income hypothesis and consumption durability analysis based on japanese panel data the permanent income hypothesis with durability of commodities is tested on a panel of about 2 000 japanese households for several commodity groups under static expectations about real interest rates and for some class of utility functions consumption which is a distributed lag function of current and past expenditure follows a martingale main empirical results are i the durability of commodities usually classified as services is substantial ii the hypothesis applies to about 85 percent of the population consisting of wage earners and iii income changes explain only a small fraction of the movements in expenditure

assessing the performance of the uk emissions trading scheme the uk s climate change programme introduced an emissions trading scheme ets for greenhouse gases firms in over 40 industrial sectors which have negotiated climate change agreements setting quantitative energy efficiency targets can use the ets to trade over and under compliance with these targets in parallel a limited number of firms have become major participants in the ets as a result of an auction of subsidies for additional abatement commitments the paper describes the uk arrangements and assesses the economic efficiency and environmental effectiveness of the ets drawing on evidence of participants behaviour both in the incentive auction and in subsequent trading

uncertain potential output implications for monetary policy abstract a small forward looking model of the euro area economy is used to investigate the implications of incomplete information about potential output for the conduct of monetary policy three results emerge first under optimal monetary policy output gap uncertainty leads to persistent deviations between the actual and the perceived output gap in response to supply and cost push shocks second in first difference form a simple policy rule such as the taylor rule continues to perform relatively well as long as the output gap is optimally estimated third incomplete information implies that it is optimal to appoint a more hawkish central bank

the effect of borrowing constraints on consumer liabilities this paper explores the effects of liquidity constraints on consumer liabilities while much empirical evidence attests to the importance of liquidity constraints in the u s economy evidence about the effects of borrowing constraints on consumer balance sheets is scarce using the 1983 survey of consumer finances data we estimate desired borrowing for unconstrained households we then evaluate the gap between predicted and observed debt for the sample of liquidity constrained consumers predicted debt is 75 percent higher than actual debt in the liquidity constrained sample thus the effect of removing borrowing constraints has quantitatively important implications for the allocation of debt in the household portfolio the removal of borrowing constraints would raise aggregate household liabilities by 9 percent copyright 1993 by ohio state university press

harvesting in an integrated general equilibrium model harvesting of prey biomass is analyzed in an integrated ecological economic system whose submodels a predator prey ecosystem and a simple economy are microfounded dynamic general equilibrium models these submodels are interdependent because the ecosystem responds to harvesting through the reactions of optimizing individual organisms by changing the provision of public ecosystem services to consumers general analytical results are derived regarding the impact of harvesting policies on short run equilibria of both submodels on population dynamics and on stationary states of the integrated model a key insight is that prey biomass carries a positive ecosystem price which needs to be added as a tax mark up to the economic price of harvested biomass to attain allocative efficiency further information on the dynamics is gained by resorting to numerical analysis of the policy regimes of zero harvesting laissez faire harvesting and efficient harvesting it is a matter of weighing costs and benefits of taking action whether the action is the inert one of leaving resources alone in order to conserve them or whether it involves exploiting a resource for so called material ends pearce 1976 p 320

the credit constrained consumer an empirical study of demand and supply in the loan market this article presents an empirical analysis of credit constrained households in which models of both demand and supply sides of the market for loans are simultaneously estimated we develop a discrete choice logit model of the consumers decision on whether or not to apply for credit combining this with a reduced form logistic model for the banks credit granting decision we then estimate the model with cross sectional data as a nonlinear ordered sequential logit our findings shed light on the criteria used by banks in assessing credit applications and reveal the strong dependence of preferences on demographic characteristics the results also suggest that agents face significant fixed costs in applying for loans the fact that we jointly estimate models of both supply and demand sides of the credit market enables us to examine whether particular groups in the population are more frequently credit rationed because they tend to demand more loans or because they are viewed as bad credit risks by lenders

mortgage default and possession under recourse a competing hazards approach recent studies by ambrose buttimer and capone have stressed the fact that lender and borrower decisions after the initial default on amortgage may significantly affect the amount and timing of recoveries and hence more broadly the value and riskiness of mortgage loan portfolios this study uses microeconomic data from the uk to examine the timing decisions of mortgage lenders and borrowers when mortgages are in default the results suggest that salary and interest rates influence timing decisions more than loan to value ratios do and that lenders and borrowers accelerate the resolution of delinquent mortgages as the economic climate deteriorates
