how much does water consumption drop when each household takes charge of its own consumption the case of the city of seville making individuals take charge of their own domestic water consumption is one of the measures used to reduce the growing demand for this resource and to achieve sustainable consumption compatible with the goal of equity the use of individual meters instead of communal meters and fixing tariffs by inhabitant rather than by household are two measures aimed at achieving these objectives this article assesses the measures put in place in the seville metropolitan area during the last 20 years with an unobserved component model set up in a state space framework estimated using maximum likelihood water consumption elasticity to individual meters has changed from 0 307 to 1 317 with the introduction of per inhabitant tariffs which demonstrates that there are water saving synergies when the two measures are implemented together the reductions in water consumption achieved with these measures are also longer lasting than the changes in consumption habits during the frequent droughts in seville

applications of behavioural economics to tax evasion the paper reviews recent models that have applied the techniques of behavioural economics to the analysis of the tax compliance choice of an individual taxpayer the construction of these models is motivated by the failure of the yitzhaki version of the allingham sandmo model to predict correctly the proportion of taxpayers who will evade and the effect of an increase in the tax rate upon the chosen level of evasion recent approaches have applied non expected utility theory to the compliance decision and have addressed social interaction the models we describe are able to match the observed extent of evasion and correctly predict the tax effect but do not have the parsimony or precision of the yitzhaki model

who ll stop lying under oath empirical evidence from tax evasion games using two earned income tax declaration experimental designs we show that only partial liars are affected by a truth telling oath a non price commitment device under oath we see no change in the number of chronic liars and fewer partial liars rather than smoothly increasing their compliance we also observe that partial liars who respond to the oath respond by becoming fully honest under oath based on both response times data and the consistency of subjects when several compliance decisions are made in a row we show that partial lying arises as the result of weak preferences towards profitable honesty the oath only transforms people with weak preferences for lying into being committed to the truth

managing water supply shortage interruption vs pricing abstract supply shortage is a common problem faced by a consumer solutions for allocating the limited supply include rationing queuing interruption and pricing while previous research has examined the welfare losses generated by each solution there is little evidence on their relative magnitudes within a common framework the objective of this paper is tospecify a model of consumer behaviour under service interruption to estimate the exact welfare loss of service interruption the same model is used to estimate the loss of a price increase intended to resolve a supply shortage using water consumption data collected for hong kong we find that relative to pricing service interruption is inefficient for water shortage management

do ethics matter tax compliance and morality in this article we argue that puzzle of tax compliance can be explained at least in part by recognizing the typically neglected role of ethics in individual behavior that is individuals do not always behave as the selfish rational self interested individuals portrayed in the standard neoclassical paradigm but rather are often motivated by many other factors that have as their main foundation some aspects of ethics we argue that it is not possible to understand fully an individual s compliance decisions without considering in some form these ethical dimensions specifically we argue here that there is much direct and indirect evidence that ethics differ across individuals and that these differences matter in significant ways for their compliance decisions we then put this in the larger context of the inability of the standard neoclassical paradigm to explain compliance of at least some individuals and we suggest several possible avenues by which theory can be expanded to incorporate ethics we conclude by arguing that a full house of compliance strategies is needed to combat tax evasion strategies that include the traditional enforcement paradigm suggested by and consistent with neoclassical theory a less traditional service paradigm that recognizes the important role of a kinder and gentler tax administration in encouraging compliance and importantly a new trust paradigm that is built on the foundation of ethics in which the tax administration must recognize that it can erode the ethics of taxpayers by its own decisions

privately operated water utilities municipal price negotiation and estimation of residential water demand the case of france this paper addresses the issue of price negotiation between a municipality and a private water utility operator and its implications for residential water demand estimation we use appropriate econometric procedures to estimate a water demand equation on a panel of french municipalities we find evidence that negotiated water price depends on municipality s characteristics causing endogeneity of price in the demand equation the impact of average household income housing and system features such as metering is investigated both on municipal consumption and price estimated price and income elasticities are significant and close to previous household level studies

valuing water supply reliability instead of creating water supply systems that fully insulate mankind from climate imposed water deficiencies it is possible that for municipal water systems a nonzero probability of water supply shortfall is efficient perfect water supply reliability meaning no chance of future shortfall is not optimal when water development costs are high designing an efficient strategy requires an assessment of consumer preferences pertaining to the reliability of water supply contingent valuations of both current and future shortfalls are reported the consistency of these measures is gauged using an expected utility model copyright 2000 oxford university press

does altruism undermine existence value abstract the debate over the use of contingent valuation for existence values or passive use values has failed to explore the validity of motives for such values one potential motive altruism has conflicting implications for benefit cost analysis depending on whether the altruist is paternalistic this paper constructs models of three types of altruism and shows how benefit cost analysis responds to each type of altruism how damage assessment and restoration depend on each type and the implications of a population of heterogeneous altruists

keeping the public purse an experiment in windfalls taxes and the incentives to restrain government it is widely believed that natural resource wealth foreign aid and other types of windfall revenue increase corruption and undermine accountability a predominant claim in political science is that windfalls free politicians from the need to tax resulting in a more politically quiescent population yet there is surprisingly little evidence to substantiate not only whether taxation has this eect but also why i use novel experiments to provide the rst micro level causal test of claims that 1 taxes motivate citizens more than windfalls to hold politicians accountable and 2 citizens care more about wasted revenue when they pay taxes the experiments were embedded in a public awareness campaign conducted with 1 863 citizens in a resource rich district in indonesia the results measured through a survey and a postcard campaign show that taxes made participants more willing to monitor government and hold politicians accountable than windfalls primarily because of a stronger sense of ownership over public funds yet when better information on government spending is made available the windfall group proved just as intolerant of misspent revenue these ndings have important implications for understanding not only how taxation motivates political action but also how revenue shapes the ways in which citizens acquire and process information on government spending

demand side management policies for residential water use who bears the conservation burden to assess the potential for urban demand side management dsm policies as a water resource management tool we analyze the extent to which price and alternative policy instruments such as use and quantity restrictions and subsidies for water efficient technologies reduce residential demand and their distributional implications by type of household using detailed household level panel data for two california communities the results suggest that the ultimate effects of dsm policies in terms of the reduction in aggregate demand and distribution of water savings among household classes depend both on the policy instrument selected and the composition of aggregate demand

tax evasion and heuristics a research note abstract the paper examines the heuristics which taxpayers use in making tax evasion decisions the following propositions are tested in an experiment using students first the taxpaper s own level of evasion will be positively related to what he perceives as the levels of evasion by others second taxpayers who have been audited are more likely to assess the probability of audit as higher and therefore decrease their levels of evasion the experimental results fail to support the first proposition but do support the second suggesting the presence of an availability effect

values elicited from open ended real experiments abstract the idea that preferences are only revealed by real incentives is deeply embedded in economists worldview consequently evidence from hypothetical experiments has not readily permeated economic thinking one method for determining whether hypothetical experiments provide useful information about preferences is to compare them to similar real goods experiments this study looks at responses elicited by three real experiments we examine the proportion of responses that meet a series of criteria that range from a broad appeal of plausibility to a narrow restriction based on quasi concavity of preferences we argue that these proportions are unreasonably low

from the lab to the field a review of tax experiments tax experiments have been gaining momentum in recent years although this literature dates back several decades with new developments in methods and data availability tax experiments have gradually moved away from lab settings and towards the field this movement from the lab to the field has happened against the background of the credibility revolution in applied economics which has seen more rigorous methods applied to policy relevant questions and of the availability to researchers of administrative data from tax returns these developments have allowed significant advances in the experimental literature on tax compliance this paper reviews this literature giving particular attention to field experiments using administrative data but putting them in the broader context of the compliance literature a particular effort is made to take a global perspective in a literature that is only recently seeing the emergence of evidence from africa latin america and asia

measuring the impact of water supply interruptions on household welfare water scarcity frequently leads to a need for rationing the choice of an adequate rationing method should be based on the impact on consumer welfare that is produced by each rationing plan some rationing schemes such as the frequently used supply interruption method can be regarded as changes in the characteristics of the good in this case time availability that do not modify the pre set consumer budget under the standard theoretical restrictions on consumer behavior compensating or equivalent variations surpluses cannot be used to identify the impacts of these methods on household welfare in this paper we propose a set of sufficient conditions with respect to the utility function that allows for the evaluation of the compensating or equivalent variations surpluses associated with changes in goods quality even if those goods are considered to be essential for consumers we use these conditions to compare the welfare losses associated with the water supply cuts implemented in seville spain to those that would result if water was instead rationed using price changes

a satisfactory benefit cost indicator from contingent valuation abstract standard economic concepts are used to develop a model of individual behavior when subject to the constraints of the contingent valuation choice context the model yields refutable consequences that are consistent with previously reported empirical findings including some that have been thought to be anomalous the model is used to show that different contingent valuation formats have predictably different performance characteristics notably the hicksian compensating measures are satisfactory benefit cost indicators when elicited using any one of several formats identified in the text of the formats examined one form of a policy referendum appears to have the most satisfactory characteristics overall we conclude that contingent valuation is a progressing research program

what do we know about the impact of microfinance the problems of statistical power and precision abstract we review all eight randomized control trial studies of microfinance published in peer reviewed journals the studies generally show no or minimal impact from providing microloans to clients and have led many researchers and policy makers to conclude that microfinance has been proven to have little or no positive impacts on people s lives we review these studies in detail and find four main results first we are able to replicate the results using the researcher s original data second we observe that while the results are generally insignificant at traditional levels most estimated coefficients are large third every one of the studies is underpowered to detect reasonable effect sizes often due to low take up of the financial product offered pooling the data from the studies together improves power for most outcomes but minimum detectable effect sizes are still large finally when we run analysis on a pooled sample we find a treatment effect on business profits business revenue and household assets significant at the 1 level we argue that existing research on the impact of microfinance is generally underpowered to identify impacts reliably and suggests that we still know very little about the impact of microfinance we end by discussing ways to improve future research

do contingent valuation estimates pass a scope test a meta analysis abstract this paper considers the scope test proposed to judge the internal consistency of contingent valuation estimates the test is shown to be quite sensitive to the maintained hypotheses required to derive fairly precise expectations for the properties of wtp functions and therefore a different approach may be needed in gauging the reliability of cv this paper describes an approach that relies on a weight of the evidence criterion and uses meta analysis to develop a systematic appraisal of what the economic values of changes in amenity resources are the approach is illustrated for the case of estimating people s willingness to pay for improving or maintaining visibility at the national parks

effect of distance on the preservation value of water quality in the past dozen years an extensive body of literature has developed on the willingness to pay for water quality in particular its recreation use and nonuse preservation values this paper illustrates a procedure for estimating the effect of distance on the preservation value of environmental quality using the contingent valuation approach the case considered is the potential degradation of water quality due to coal mining activity in the flathead river drainage system montana the analysis supports a negative association for this particular study area the effect of distance on preservation value was considered both directly and indirectly through its effect on visits 36 references 2 tables

no taxation without information deterrence and self enforcement in the value added tax abstract claims that the vat facilitates tax enforcement by generating paper trails on transactions between firms contributed to widespread vat adoption worldwide but there is surprisingly little evidence this paper analyzes the role of third party information for vat enforcement through two randomized experiments among over 400 000 chilean firms announcing additional monitoring has less impact on transactions that are subject to a paper trail indicating the paper trail s preventive deterrence effect this leads to strong enforcement spillovers up the vat chain these findings confirm that when taking evasion into account significant differences emerge between otherwise equivalent forms of taxation jel d83 h25 h26 k34 o17

estimating residential water demand in the presence of free allowances the main aim of this paper is to quantify the impact of a rate structure which includes a free allowance on residential water consumption the analysis here differs from most previous research in that it explicitly recognizes that water consumption above the free allowance being sensitive to price responds less to social and climatic factors than consumption below the free allowance while the model specification and estimation procedures used here should be of interest to those interested in the demand for water the results using data for adelaide south australia on the determinants of water consumption should be of interest to water authorities

yea saying in contingent valuation surveys a number of recent papers have provided estimates of willingness to pay derived in contingent valuation surveys exceeding those revealed in experimental or real life markets one possible explanation for the overestimation of values is the presence of yea saying with the objective of reducing the occurrence of yea saying a new elicitation format referred to as the dissonance minimizing d m format is proposed an empirical comparison of the dm format with the conventional dichotomous choice dc format and the ambivalence reducing polychotomous choice pc format suggested by ready whitehead and blomquist 1995 is made results are encouraging for the dm

tax morale affects tax compliance evidence from surveys and an artefactual field experiment our working hypothesis is that cross cultural differences in tax compliance behavior have foundations in the institutions of tax administration and citizen assessment of the quality of governance tax compliance being a complex behavioral issue its investigation requires use of a variety of methods and data sources results from artefactual field experiments conducted in countries with substantially different political histories and records of governance quality demonstrate that observed differences in tax compliance levels persist over alternative levels of enforcement the experimental results are shown to be robust by replicating them for the same countries using survey response measures of tax compliance

evaluation of nonmarket goods recovering unconditional preferences a new approach is proposed for the evaluation of nonmarket goods starting from a complete or incomplete conditional demand system for market goods which is observable and depends on nonmarket goods this information is not sufficient to recover the underlying preference ordering of the representative consumer the central idea is to employ additional marginal willingness to pay functions for the nonmarket goods since they can be estimated either together with the demand system or in a separate step they are less arbitrary than the assumptions or hypotheses usually made if the entire system is weakly integrable the underlying ordering and appropriate welfare measures can be derived in this article i investigate the relationship between conditional and unconditional demand systems present sufficient conditions for weak integrability and demonstrate the practicability of the procedure proposed by means of three examples

ghostbusting in detroit evidence on nonfilers from a controlled field experiment abstract many people who owe income tax fail to file a timely tax return in communication with these ghosts what messages from the tax authority are effective for eliciting a return this is the first study to address message content in communication with income tax nonfilers i assess the efficacy of messages related to penalty salience punishment probability compliance cost and civic pride by evaluating the response to experimental mailings distributed by detroit to 7142 suspected resident nonfilers the penalty salience message was the most effective relative to a basic mailing that requested a return penalty salience mailings that stated the statutory penalty for failing to file a return tripled response rates from 3 to 10 compliance cost mailings that enclosed a blank tax return and punishment probability mailings that stated the recipient s federal income also raised response rates relative to the basic mailing but civic pride mailings did not i investigate the impact of treatment mailings on the behavior of untreated neighbors and find no evidence of geographic network effects

the credibility revolution in empirical economics how better research design is taking the con out of econometrics since edward leamer s memorable 1983 paper let s take the con out of econometrics empirical microeconomics has experienced a credibility revolution while leamer s suggested remedy sensitivity analysis has played a role in this we argue that the primary engine driving improvement has been a focus on the quality of empirical research designs the advantages of a good research design are perhaps most easily apparent in research using random assignment we begin with an overview of leamer s 1983 critique and his proposed remedies we then turn to the key factors we see contributing to improved empirical work including the availability of more and better data along with advances in theoretical econometric understanding but especially the fact that research design has moved front and center in much of empirical micro we offer a brief digression into macroeconomics and industrial organization where progress by our lights is less dramatic although there is work in both fields that we find encouraging finally we discuss the view that the design pendulum has swung too far critics of design driven studies argue that in pursuit of clean and credible research designs researchers seek good answers instead of good questions we briefly respond to this concern which worries us little

taxpayer response to an increased probability of audit evidence from a controlled experiment in minnesota abstract in 1995 a group of 1724 randomly selected minnesota taxpayers was informed by letter that the returns they were about to file would be closely examined compared to a control group that did not receive this letter low and middle income taxpayers in the treatment group on average increased tax payments compared to the previous year which we interpret as indicating the presence of noncompliance the effect was much stronger for those with more opportunity to evade in fact the difference in differences is not statistically significant for those who do not have self employment or farm income and do not pay estimated tax surprisingly however the reported tax liability of the high income treatment group fell sharply relative to the control group

valuing public goods with the contingent valuation method a critique of kahneman and knetsch the social stakes in the use and abuse of the contingent valuation method cvm are very high recent developments in environmental law have elevated the cvm to the status of a refutable presumption in cases brought under certain statutes it is no longer adequate for economists to sniff at the continued popularity of the cvm in such cases it is instead incumbent on economists to come to some conclusions as to the domain under which the cvm may or may not be correctly applied one should not expect a simple thumbs up or thumbs down assessment in this matter such an expectation would be naive with respect to the inherent complexity of the issue not to mention the financial incentives that expert witnesses might have to breed as if controversy in an adversarial legal system in this context the strong admonitions of kahneman and knetsch 3 kk against the casual use of the cvm must be carefully examined they present what they believe to be evidence to support the claim that the cvm suffers from an embedding effect and that any reported willingness to pay wtp is best interpreted as the purchase of moral satisfaction rather than as a measure of the value associated with a particular public good i argue that their evidence is insufficient to test the implied hypotheses that it is incorrectly reported and that it is in large measure fully consistent with received economic theory

the value of water supply reliability in urban water systems abstract reliability is an important dimension of urban water supply while out of pocket losses appear small water customers place high values on reliability this demand for reliability can be measured by contingent valuation methods while the costs of providing various levels of reliability can be estimated through hydrologic simulation a framework for optimizing reliability is presented and the contingent valuation survey is described results from three colorado towns are presented

does the classic microfinance model discourage entrepreneurship among the poor experimental evidence from india do the repayment requirements of the classic microfinance contract inhibit investment in high return but illiquid business opportunities among the poor using a field experiment we compare the classic contract which requires that repayment begin immediately after loan disbursement to a contract that includes a two month grace period the provision of a grace period increased short run business investment and long run profits but also default rates the results thus indicate that debt contracts that require early repayment discourage illiquid risky investment and thereby limit the potential impact of microfinance on microenterprise growth and household poverty jel a21 g32 i32 l25 l26 o15 o16

unwilling or unable to cheat evidence from a tax audit experiment in denmark this paper analyzes a tax enforcement field experiment in denmark in the base year a stratified and representative sample of over 40 000 individual income tax filers was selected for the experiment half of the tax filers were randomly selected to be thoroughly audited while the rest were deliberately not audited the following year threat of audit letters were randomly assigned and sent to tax filers in both groups we present three main empirical findings first using baseline audit data we find that the tax evasion rate is close to zero for income subject to third party reporting but substantial for self reported income since most income is subject to third party reporting the overall evasion rate is modest second using quasi experimental variation created by large kinks in the income tax schedule we find that marginal tax rates have a positive impact on tax evasion for self reported income but that this effect is small in comparison to legal avoidance and behavioral responses third using the randomization of enforcement we find that prior audits and threat of audit letters have significant effects on self reported income but no effect on third party reported income all these empirical results can be explained by extending the standard model of rational tax evasion to allow for the key distinction between self reported and third party reported income

sequencing and valuing public goods abstract this paper establishes several propositions concerning the importance of context in valuing public goods it first provides necessary and sufficient conditions for the value of a public good to be independent of context utility constant valuation sequences are considered where public goods are systematically made available or taken away for the case of strict hicksian substitutes willingness to pay for an increase in one of the public goods is strictly decreasing the farther out in a sequence it is valued for the destruction of public goods the reverse is true for willingness to accept compensation sequencing has opposite implications for the assessment of the benefits of providing public goods than for the assessment of the damage from destroying them

beyond baseline and follow up the case for more t in experiments the vast majority of randomized experiments in economics rely on a single baseline and single follow up survey if multiple follow ups are conducted the reason is typically to examine the trajectory of impact effects so that in effect only one follow up round is being used to estimate each treatment effect of interest while such a design is suitable for study of highly autocorrelated and relatively precisely measured outcomes in the health and education domains this paper makes the case that it is unlikely to be optimal for measuring noisy and relatively less autocorrelated outcomes such as business profits household incomes and expenditures and episodic health outcomes taking multiple measurements of such outcomes at relatively short intervals allows the researcher to average out noise increasing power when the outcomes have low autocorrelation it can make sense to do no baseline at all moreover the author shows how for such outcomes more power can be achieved with multiple follow ups than allocating the same total sample size over a single follow up and baseline the analysis highlights the large gains in power from ancova rather than difference in differences when autocorrelations are low and a baseline is taken the paper discusses the issues involved in multiple measurements and makes recommendations for the design of experiments and related non experimental impact evaluations

honesty and evasion in the tax compliance game conventional models of tax compliance emphasize that taxpayers make strategic tax reports underreporting income to the extent that this behavior is functionally rewarded in contrast to this view considerable empirical evidence suggests that many taxpayers are inherently honest reporting truthfully regardless of the incentive to cheat in this article we build a game theoretic model of tax compliance that includes both honest and potentially dishonest taxpayers we show that including honest taxpayers significantly alters the model leading to much improved empirical predictions and somewhat different and novel policy implications

taxpayer confusion evidence from the child tax credit we develop an empirical test for whether households understand or misperceive their marginal tax rate our identifying variation comes from the loss of the child tax credit when a child turns 17 using this age discontinuity we find that despite this tax liability increase being lump sum and predictable households reduce their reported wage income upon discovering they have lost the credit this finding suggests that households misinterpret at least part of this tax liability change as an increase in their marginal tax rate this evidence supports the hypothesis that tax complexity can cause confusion and leads to unintended behavioral responses jel d12 d14 h24 h31

is all domestic water consumption sensitive to price control this paper presents a model of residential water demand based on the stone geary utility function which explicitly considers a threshold of water that is insensitive to price and a quantity that can adapt instantaneously to price changes first the threshold is assumed constant being then allowed to vary according to past levels of consumption a proxy for households water using equipment and habits a measure of the depreciation rate of habits is derived and the effectiveness of price and non price conservation measures are compared the results provide useful policy recommendations for the studied case of seville spain

evaluating the welfare effects of reforming municipal water prices abstract despite the strong criticisms by economists of water utility pricing practices and the presence of well articulated theoretical models of efficient pricing alternatives few empirical studies have documented the magnitude of the efficiency gains from altering water prices the structures of water supply costs and water demands are estimated using data from vancouver canada a simulation program uses these estimated relationships to compute the impact upon a representative water utility s output and deficit and upon aggregate consumer surplus of a move from its current practice to efficient prices simulation results show that a move to seasonally differentiated pricing with an annual charge calculated to recoup the resulting deficit raises aggregate surplus by approximately 4 this result contrasts with recent water pricing studies that found welfare improvements of approximately 1

contingent valuation controversies and evidence contingent valuation cv has become one of the most widely used non market valuation techniques cv s prominence is due to its flexibility and ability to estimate total value including passive use value its use and the inclusion of passive use value in benefit cost analyses and environ mental litigation are the subject of a contentious debate this paper discusses key areas of the debate over cv and the validity of passive use value we conclude that many of the alleged problems with cv can be resolved by careful study design and implementation we further conclude that claims that empirical cv findings are theoretically inconsistent are not generally supported by the literature the debate over cv however has clarified several key issues related to nonmarket valuation and can provide useful guidance both to cv practitioners and the users of cv results

the impact of public transfer expenditures on tax evasion an experimental approach abstract this paper outlines the methodology and results of an experiment undertaken to analyze primarily the impact of public sector transfer payments on tax evasion behaviour apart from the use of transfer payments further explanatory variables used were income expected auditing probability and perceived tax burden the influence of these variables on both the propensity to evade taxes and the extent of taxes evaded are investigated in an attempt to add more realism some innovative changes to the experimental approach were incorporated

controlling contradictions among regulations the decade of the 1970s imposed environmental and health and safety regulations throughout the economy adding to the economic regulation equal opportunity regulation and other prior government regulation different parts of the environmental protection agency dictate how a company will handle its liquid gaseous and solid wastes while the occupational safety and health administration requires that workers be protected against harmful exposures to the chemicals although the depressed auto industry received national attention many other aspects of the economy are subject to contradictory regulations generated by the one at a time approach of congress to externalities although the more general analysis proposed by the author is more difficult to implement the effort is necessary 8 references

testing for temporal reliability in contingent valuation with time for changes in factors affecting demand we develop a temporal reliability test of the contingent valuation method separate random samples were administered the same telephone survey five years apart in the retest respondents have less favorable attitudes toward the environment given this result a temporally reliable contingent valuation would find lower willingness to pay we find that the estimates are temporally reliable after accounting for attitudes which have changed over the five year period values are not significantly different five years apart this study provides additional evidence that use of the contingent valuation method can provide useful information for environmental policy analysis

information and the divergence between willingness to accept and willingness to pay abstract there is considerable empirical and experimental evidence that there is a divergence between willingness to accept compensation to give up a good and willingness to pay to obtain a good this divergence persists even when the good in question is small relative to income a result in apparent conflict with standard economic theory this paper develops a theoretical bidding model with costly information acquisition to explain this divergence the model generates a gap between offers to sell and bids to buy consistent with the experimental results we argue that the model does a better job of explaining empirical and experimental data than either of the two commonly invoked theoretical explanations the endowment effect and the substitution effect

cheating ourselves the economics of tax evasion no government can announce a tax system and then rely on taxpayers sense of duty to remit what is owed some dutiful people will undoubtedly pay what they owe but many others will not over time the ranks of the dutiful will shrink as they see how they are being taken advantage of by the others thus paying taxes must be made a legal responsibility of citizens with penalties attendant on noncompliance but even in the face of those penalties substantial tax evasion exists and always has the history of taxation is replete with episodes of evasion often notable for their inventiveness during the third century many wealthy romans buried their jewelry or stocks of gold coin to evade the luxury tax and homeowners in eighteenth century england temporarily bricked up their fireplaces to escape notice of the hearth tax collector webber and wildavsky 1986 p 141 this essay reviews what is known about the magnitude nature and determinants of tax evasion with an emphasis on the u s income tax alm 1999 andreoni erard and feinstein 1998 and slemrod and yitzhaki 2002 offer more comprehensive recent reviews of the literature it then places this information into a conceptual and policy context

tax farming redux experimental evidence on performance pay for tax collectors performance pay for tax collectors has the potential to raise revenues but might come at a cost if it increases the bargaining power of tax collectors vis a vis taxpayers we report the first large scale field experiment on these issues where we experimentally allocated 482 property tax units in punjab pakistan into one of three performance pay schemes or a control after two years incentivized units had 9 4 log points higher revenue than controls which translates to a 46 higher growth rate the scheme that rewarded purely on revenue did best increasing revenue by 12 9 log points 64 higher growth rate with little penalty for customer satisfaction and assessment accuracy compared to the two other schemes that explicitly also rewarded these dimensions the revenue gains accrue from a small number of properties becoming taxed at their true value which is substantially more than they had been taxed at previously the majority of properties in incentivized areas in fact pay no more taxes but instead report higher bribes the results are consistent with a collusive setting in which performance pay increases collectors bargaining power over taxpayers who have to either pay higher bribes to avoid being reassessed or pay substantially higher taxes if collusion breaks down

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

why people pay taxes the case of the development levy in tanzania abstract this paper examines factors determining tax compliance behavior in local authorities in tanzania the case study is the poll tax locally named development levy the study finds support for the hypothesis that tax compliance is positively related to factors such as ability to pay the perceived probability of being prosecuted and the number of tax evaders known personally by the respondent oppressive tax enforcement harassment of taxpayers and discontent with public service delivery seem to increase tax resistance and may explain widespread tax evasion

the impact of group based credit programs on poor households in bangladesh does the gender of participants matter this paper estimates the impact of participation by gender in the grameen bank and two other group based micro credit programs in bangladesh on labor supply schooling household expenditure and assets the empirical method uses a quasi experimental survey design to correct for the bias from unobserved individual and village level heterogeneity we find that program credit has a larger effect on the behavior of poor households in bangladesh when women are the program participants for example annual household consumption expenditure increases 18 taka for every 100 additional taka borrowed by women from these credit programs compared with 11 taka for men

household responses to increased water rates during the california drought this paper explores the use of fixed effects and maximum likelihood techniques to es timate household responses to water price in creases during the california drought estimates are based on bimonthly meter readings from 599 single family households in the alameda county water district over the period 1982 1992 before and after the introduction of a steeply increasing block rate price structure i find that household and monthly fixed effects models are not success ful in modeling water demand with these data however maximum likelihood models that ex plicitly consider the household s response to the rate structure result in plausible estimates of wa ter demand jel q25

analysing rationing policies drought and its effects on urban users welfare analysing rationing policies during drought the aim of this paper is to study the impact on consumers of rationing policies implemented during water shortages water scarcity gives rise to the need for rationing and various methods including supply cutoffs can be used a model is devised to quantify the welfare losses associated with qualitive and quantitive restrictions based on virtual prices and using the consumer surplus as a welfare measurement welfare variations for different users have been calculated to achieve the aim information relative to seville spain has been used analysing the drought period that took place in the first half of the 1990s it has been possible to observe the main source that led to welfare losses for each kind of user

tax compliance and psychic costs behavioral experimental evidence using a physiological marker although paying taxes is a key element of a well functioning society there is still limited understanding as to why people actually pay their taxes models emphasizing that taxpayers make strategic financially motivated compliance decisions seemingly assume an overly restrictive view of human nature law abidance may be more accurately explained by social norms a concept that has gained growing importance as research attempts to understand the tax compliance puzzle this study analyzes the influence of psychic stress generated by the possibility of breaking social norms in the tax compliance context we measure psychic stress using heart rate variability hrv which captures the psychobiological or neural equivalents of psychic stress that may arise from the contemplation of real or imagined actions producing immediate physiologic discomfort the results of our laboratory experiments provide empirical evidence of a positive correlation between psychic stress and tax compliance thus underscoring the importance of moral sentiments for tax compliance we also identify three distinct types of individuals who differ in their levels of psychic stress tax morale and tax compliance

informing climate adaptation a review of the economic costs of natural disasters abstract this paper reviews the empirical literature on the economic impacts of natural disasters to inform both the modeling of potential future climate damages and climate adaptation policy related to extreme events it covers papers that estimate the short and or long run economic impacts of weather related extreme events as well as studies identifying the determinants of the magnitude of those damages including fatalities the paper also reviews the small number of empirical papers on the potential extent of adaptation in response to changing extreme events

the relationship between the income elasticities of demand and willingness to pay abstract the relationship between income and willingness to pay for collectively provided public environmental goods is investigated we show that while the income elasticity of willingness to pay and the ordinary income elasticity of demand are related knowledge of one is insufficient to determine the magnitude or even the sign of the other the income elasticity of willingness to pay is influenced by additional factors which are generally unobservable examples are provided to illustrate the degree to which the two income elasticities may diverge our results indicate that even when goods are demand luxuries they may or may not have income elasticities of willingness to pay which are greater than one

test retest reliability of contingent valuation with independent sample pretest and posttest control groups test retest the standard method used to investigate reliability of contingent valuation is limited because when the time period between the two surveys is relatively short the study may exhibit testing recall conversely when the time between the two surveys increases there is an increased chance the true value will change the test retest design cannot isolate these effects independent pretest and posttest control groups allow testing of reliability even when recall occurs or the true value changes using this design we found ex post estimates of hicksian surplus are reliable regardless of whether respondents have direct experience with an activity

residential water demand in the northwest of spain a panel of monthly aggregate data from the northwest of spain is used to estimate domestic water demand functions under linear and non linear tariffs price billing climatic and sociodemographic variables are used as explanatory variables the use of intraannual data constitutes a relevant contribution in the european context overall marginal price elasticity estimates lie between 0 12 and 0 17 summer only elasticities and elasticities associated with uses beyond the effectively free allowances seem significantly higher climatic variables significantly affect monthly use although probably less than in other wealthier and drier areas domestic water use appears to be a normal good

the impact of microcredit borrowing on household consumption in bangladesh the rapid expansion of microcredit in recent years renders knowledge of its impact on poverty critical unfortunately empirical investigations have been limited by endogeneity issues and randomiz

the use of field experiments to increase tax compliance governments have become increasingly interested in the explosion of research into taxpayer behaviour this article briefly reviews two main theories of tax compliance deterrence and non deterrence before discussing the recent rapid rise of natural field experiments nfes in this area these nfes represent a win win for policy makers and academics since they can test theories while also evaluating the impact of a specific intervention in the real world the evidence from nfes shows that deterrence approaches improve compliance while the case for non deterrence approaches is less conclusive at the moment nfes could be improved by paying more attention to findings from behavioural science that apparently incidental factors such as timing framing and complexity substantially affect whether compliance occurs or not new directions for future studies include network effects tax payments in addition to declarations the behaviour of firms the provision of public goods and the relationship between attitudes and behaviour
