willingness to pay for quality improvements comparative statics and interpretation of contingent valuation results this paper extends variation function theory by examining the effects of changes in prices quality and income on willingness to pay for quality change comparative static effects are found for both on site users and nonusers of the resource these results are used to interpret contingent valuation empirical models for example the substitution and complementary relationships between trips to natural resource sites can be identified this paper also suggests tests for comparison of contingent valuation with recreation demand models and other tests of validity

blessing or curse impacts of the brazilian pre salt oil exploration abstract the discoveries of oil and gas in the so called pre salt layer have triggered a lot of discussions about their economic effect in this paper we discuss in detail a less discussed dimension the impact of pre salt layer in the structure of the brazilian economy especially the composition of the industry and exports similar consequences in the country of dutch disease and deindustrialization due to revenues from oil exports are evaluated the methodology used is a dynamic global general equilibrium model with specific features for the treatment of the issues raised

corruption and the shadow economy one way or two way street this paper attempts to bring some resolution to the relation between corruption and the shadow economy while previous research focuses on the static relationship between the two we account for dynamics using a panel vector autoregression model and consider influences from the official economy and institutional quality using cross national panel data for 108 countries over the period 1984 2006 results show a bidirectional relationship with initial complementarity and substitution over time thus the nature of the two way street is shown to change over time and our consideration of dynamics reveals the complementarity substitution switch

the nexus of white collar crimes shadow economy corruption and uninsured motorists abstractthis article empirically examines the nexus of three white collar crimes shadow economy corruption and uninsured motorists whereas the shadow economy corruption linkage has been studied the linkages with uninsured motorists have not been formally studied results based on us data and accounting for possible bidirectional causalities show complementarity between shadow economy and corruption and between uninsured motorists and the shadow economy the magnitude of the impact of uninsured motorists on the shadow economy is greater than that of corruption in other findings shadow economy was lower in most prosperous states and in states that did not impose a sales tax

temporal stability of stated preferences for endangered species protection from choice experiments abstract benefit transfer methods rely on past models and results so it is important to know whether economic values are stable over time or are subject to change either because of the reliability of the methodology or due to actual preference changes the temporal stability of willingness to pay wtp has been tested extensively for contingent valuation but rarely for stated preference choice experiments ce we use data from two identical ce surveys on different samples from the same population that occurred 17 months apart spring 2009 and fall 2010 to estimate and compare mean wtp and preference parameters associated with threatened and endangered marine species protection our models account for both preference and scale heterogeneity and the results suggest both types of heterogeneity matter tests of preference stability suggest stable preferences between 2009 and 2010 furthermore wtp values estimated from both surveys are not statistically different this provides evidence that economic values estimated using ce methods are temporally stable

comment on cameron s censored logistic regression model for referendum data abstract t a cameron a new paradigm for valuing non market goods using referendum data maximum likelihood estimation by censored logistic regression j environ econom management 15 355 379 1988 presents what she terms a new paradigm for interpreting referendum data derived from contingent valuation surveys for nonmarket resources we show that since her model is a reparameterization of the usual logistic regression model asymptotic standard errors can be derived for the maximum likelihood estimators of the parameters in either model from the other we also argue that computational convenience in deriving demand relationships or elasticities depends more on the choice of welfare measure than on the choice of a parameterization

the hidden economy as an unobserved variable abstract the technique of unobserved variables is used to estimate the relative size and development time of the hidden economy of oecd countries the burdens of taxation and regulations and the tax morality turn out to be statistically significant determinants at the end of the scandinavian and benc lux countries are expected to have a relatively large and japan and switzerland a relatively small hidden economy canada and the united states are rank in the middle the size of all hidden sectors is estimated to have increased in the period 1960 1973 relative to officially measured gnp

comparative reliability of the dichotomous choice and open ended contingent valuation techniques abstract the comparative reliability of dichotomous choice and open ended contingent valuation methods cvm is evaluated by resurvey of the same households 9 months after their original survey test retest correlations on willingness to pay are statistically significant at the 1 level and range from 0 57 for the dichotomous choice cvm to 0 62 for the open ended cvm the test retest correlations were not statistically different between dichotomous choice and open ended cvm a likelihood ratio test for temporal stability of each method s willingness to pay functions indicates stability half of the time for both methods

giving stated preference respondents time to think results from four countries previous studies have found that contingent valuation cv respondents who are given overnight to reflect on a cv scenario have 30 40 lower average willingness to pay wtp than respondents who are interviewed in a single session this time to think ttt effect could explain much of the gap between real and hypothetical wtp observed in experimental studies yet giving time to think is still rare in binary or multinomial discrete choice studies we review the literature on increasing survey respondents opportunities to reflect on their answers and synthesize results from parallel ttt studies on private vaccine demand in four countries across all four countries we find robust and consistent evidence from both raw data and multivariate models for a ttt effect giving respondents overnight to think reduced the probability that a respondent said he or she would buy the hypothetical vaccines average wtp fell approximately 40 respondents with time to think were also more certain of their answers and a majority said they used the opportunity to consult with their spouse or family we conclude with a discussion of why researchers might be hesitant to adopt the ttt methodology

the informal sector in developed and less developed countries a literature survey the main goal of this study is two fold 1 to provide ageneral overview of the contributions to the literature on theinformal sector with a special focus on the public choiceapproach and 2 to compare these contributions across twoinstitutionally different types of countries developed andless developed developing and transition countries thepaper focuses on the criteria used to define the informalsector the relationship between the formal and informaleconomy tax evasion and public choice analysis it isstressed throughout this paper that the distinction betweenthe two types of countries is of key importance

interpretation and temporal stability of cv bids for wildlife existence a panel study existence values are playing an increasingly important role in wildlife preservation decisions but little is known about how these values behave over time and value estimates may often be misinterpreted panel study results suggest that although existence values may be relatively stable many individuals respond to contingent valuation by bidding their fair share or for the satisfaction from contributing to a good cause such as environmental quality although payment of fair share may represent a lower bound estimate of existence value payment for a good cause may or may not be closely related to the value of the resource itself

unemployment and international shadow economy gender differences abstractadding to the body of research on cross country determinants of the informal economy this article studies how unemployment differences across gender drive the propensities to work in the informal sector results accounting for possible simultaneity between unemployment and the shadow economy show that unemployed males rather than unemployed females were more likely to operate underground these findings about greater male propensities are generally robust to alternative considerations

mandatory versus voluntary payment for green electricity summary renewable energy sources have a critical role to play in contributing to the diversity sustainability and security of energy supplies the main objective of the paper is to gain an understanding of the support mechanism of renewable energy sources most preferred by households in the united kingdom this paper analyses households preferences and willingness to pay under a mandatory scheme where all households contribute compared to a voluntary scheme where only those who wish to pay to support renewables do so such as the green tariffs offered by electricity suppliers in the uk two self designed contingent valuation method cvm surveys are used to explore whether the type of payment option has an impact on households willingness to pay wtp for increasing share of renewable energy in electricity generation the paper also investigates whether the type of payment mode affects respondents self reported certainty of paying their stated valuations the results indicate that the likelihood of paying a positive amount for supporting renewable energy is higher under a mandatory scheme compared to a voluntary payment option in the uk respondents have a higher level of certainty in paying their stated wtp under a mandatory payment scheme

disentangling the pure time effect from site and preference heterogeneity effects in benefit transfer an empirical investigation of transferability two identical open ended contingent valuation surveys assessing willingness to pay for better protection against flooding were administered in 2005 and 2010 at the same site the 2010 survey was administered to the same respondents as those interviewed in 2005 as well as to new participants this experimental design allows us to separate the pure temporal dimension from the spatial and social dimensions of transferability thereby permitting an investigation of the temporal reliability associated with a transfer of value estimates over a 5 year time horizon having isolated the pure effect of time the design further allows assessing the social dimension of transferability

reliability and predictive validity of contingent values does the nature of the good matter abstract because the contingent valuation mechanism cvm elicits verbal reports of maximum willingness to pay and not actual willingness to pay analysts have expressed doubts about the reliability and validity of contingent values for commodities such as environmental amenities this skepticism is usually attributed to the amorphous nature of the commodity and to peoples lack of familiarity or experience however our comparison of two commodities which lie at polar extremes of the private good public good continuum suggests that the nature of the good may have little influence on the reliability and predictive validity of the cvm instead aspects of the cvm itself e g explicit payment obligation may be more important for high intention behavior consistency

a new paradigm for valuing non market goods using referendum data maximum likelihood estimation by censored logistic regression abstract this paper challenges the w m hanemann amer j agr econom 66 332 341 1984 and c sellar j p chavas and j r stoll j environ econom management 13 382 390 1986 utilizations of logit models to estimate the value of non market resources from referendum survey data these data are more informative than conventional choice data the random utility interpretation of logit models is therefore too restrictive bypassing the utility function entirely it will be shown that parameters and standard errors for utility theoretic inverse hicksian demand functions can be extracted directly and much more simply estimated demand functions need not be limited to those corresponding to the linear in parameters utility difference specifications which can be handled by packaged logit programs

distributional coalitions state strength and economic growth toward a comprehensive theory of economic development high performing economies in the asia pacific region together with only mediocre economic development in latin america prompts the question of what explains differential economic growth rates among developing countries combining a statist perspective with olson s theory of interest group formation this research hypothesizes that nations with weak distributional coalitions will more likely experience high growth and state intervention will be effective using a longitudinal research design this secondary analysis involves a comparative and interactive examination of eight asian pacific and twelve latin american countries by considering the role of the state in interaction with distributional coalitions in society the results indicate that approximately two thirds of the variance in national economic growth is explained

corruption and the shadow economy an empirical analysis this paper analyzes the influence of the shadow economy on corruption and vice versa we hypothesize that corruption and the shadow economy are substitutes in high income countries while they are complements in low income countries the hypotheses are tested for a cross section of 98 countries our results show that there is no robust relationship between corruption and the size of the shadow economy when perceptions based indices of corruption are used employing an index of corruption based on a structural model however corruption and the shadow economy are complements in countries with low income but not in high income countries

choice consistency and preference stability in test retests of discrete choice experiment and open ended willingness to pay elicitation formats this study tests the temporal stability of preferences choices and willingness to pay wtp values using both discrete choice experiment dce and open ended oe wtp elicitation formats the same sample is surveyed three times over the course of two years using each time the same choice sets choice consistency is positively correlated with choice certainty and choice complexity the impact of choice complexity fades away in time most likely as a result of learning and preference refinement although the oe wtp values remain stable over a time period of 2 years as in previous stated preference studies dce based wtp measures differ significantly suggesting their use in benefits transfer may be limited

shadow economies size causes and consequences using various methods the size of the shadow economy in 76 developing transition and oecd countries is estimated average size varies from 12 percent of gdp for oecd countries to 23 percent for transition countries and 39 percent for developing countries increasing taxation and social security contributions combined with rising state regulations are driving forces for the increase of the shadow economy especially in oecd countries according to some findings corruption has a positive impact on the size of the shadow economy and a growing shadow economy has a negative effect on official gdp growth

as time goes by examination of temporal stability across stated preference question formats we evaluate the temporal stability of willingness to pay values obtained from two identical stated preference surveys undertaken in 2004 and 2012 the surveys employ two discrete choice elicitation formats to value reductions in two health endpoints related to tap water consumption and are explicitly designed to make direct comparisons between formats we find no significant differences in real willingness to pay between the two surveys for either format a result that is robust to the structure of heterogeneity used to model respondent preferences findings lend support at least within the context of tap water quality to the temporal transfer of nonmarket benefits over extended time periods

the rise and decline of mancur olson s view of the rise and decline of nations author affiliation j barkley rosser jr department of economics msc 0204 james madison university harrisonburg va 22807 usa rosserjb jmu edu acknowledgment the author thanks roger r betancourt and thomas c schelling for providing either useful comments or materials and dennis coates and jac c heckelman for careful editing of earlier drafts of this paper the author is responsible for any remaining errors or misinterpretations 1 introductionalthough the first book by mancur lloyd olson jr 1the logic of collective action 1965 has been cited more often and can be viewed as more fundamentally innovative at the theoretical level its successor the rise and decline of nations 1982 has been more widely translated and is arguably the magnum opus of his career the grand application of his earlier ideas to the world and history at large 2 the earlier work laid out the problems that groups have in their collective goals as they grow larger with a greater disjuncture arising between the interests of the individual and of the collective group in the final chapter of this work he suggested that his argument could lead to an overturning of the orthodox theory of pressure groups that saw them as a positive force for democracy and efficiency luce 1924 commons 1950 special interest groups representing small numbers of firms in oligopolistic industries could support monopolistic or protectionist legislation such legislation could damage the broader economy especially groups unable to organize themselves that would then have to suffer in silence although olson rarely used the term this argument can be seen as foreshadowing the later theory of rent seeking and in his later works he more openly recognized the affinity of his ideas with the public choice school of thought 3although olson added a number of arguments two crucial innovations appear in rise and decline that underlie its central thesis one is the distinction between distributional coalitions which are seen as leading to outcomes inimical to economic growth and encompassing coalitions which are seen as potentially aiding economic growth in a society because of their greater size the latter are seen as having trouble organizing themselves and achieving influence although they might have a better chance of doing so in a smaller and more homogeneous society such as sweden olson s other innovation was his argument that over time a stable democracy will tend to create more and more distributional coalitions whose political power will accumulate thus gradually impeding the economic growth of the society this becomes the key to his most famous argument in rise and decline he especially focused on the post world war ii performance of germany and japan compared with the united kingdom he argued that the defeat of germany and japan in the war led to the overthrow of the power of narrow special interest groups that impeded growth whereas in the united kingdom such groups reached a peak of power that was responsible for the relatively weak performance of the british economy he emphasized that this was not a sudden development but that after leading the world in economic growth during the industrial revolution during the long eighteenth century 1688 1834 britain began to fall behind in the mid 19th century compared with such rising powers as germany and the united states this deceleration and relative decline only worsening in the aftermath of world war ii although he discussed a variety of other examples this was the book s central inspiring case of course even as rise and decline was being published the united kingdom began to undergo a substantial political and economic transformation during the period of rule by margaret thatcher that triggered a global movement to privatization and marketization even though britain was not invaded and did not experience a violently revolutionary upheaval

moose hunting values in sweden now and two decades ago the swedish hunters revisited this paper is based on two national contingent valuation studies dealing with the extent and economic values of hunting in sweden the first valuation study was conducted in 1987 and the second in 2006 both the game resource and the hunter community have undergone changes in the two decades covered by the surveys an important purpose of the latter survey was to repeat relevant parts of the former one which created a rare opportunity to compare valuations covering a very long time span moose hunting value and its determinants were compared between the two studies showing that significant changes have taken place our analysis suggests caution in using results from old contingent valuation studies for e g benefits transfer exercises

does capital punishment deter white collar crimes this paper examines whether capital punishment either directly or via a spillover effect has a deterrent effect on white collar crimes using data on nearly 150 nations and various dimensions of capital punishment including capital punishment for non violent crimes we consider two widely prevalent white collar crimes corruption and the shadow economy nesting the empirical analysis in the broader literature on determinants of corruption and the shadow economy we find that capital punishment in general reduced both corruption and the shadow economy and the deterrent effect on the shadow economy was relatively more prevalent adding some empirical insights to the theoretical arguments surrounding the desirability of maximal punishments results show some trade off between the quantity and quality of punishment

quantifying the premium externality of the uninsured in some insurance markets the uninsured can generate a negative externality on the insured leading insurance companies to pass on costs as higher premia using a novel panel data set and a staggered policy change that exogenously varied the rate of uninsured drivers at the county level in california we quantitatively investigate the effect of uninsured motorists on automobile insurance premia consistent with predictions of theory we find uninsured drivers lead to higher insurance premia specifically a 1 percentage point increase in the rate of uninsured drivers raises insurance premia by between 1 2 we also discuss corrective pigouvian taxes

consumption process and multiple valuation of landscape attributes abstract environmental valuation can be seen as a process which evolves as individuals reflect on their consumption experience in this paper we consider how environmental values could change as the subject has reached the end of the consumption process a split sample comparison is conducted for estimating the values tourists give to a set of landscape attributes the first subsample was taken on site as subjects were on a tour contemplating the landscape of the island of gran canaria canary islands the second subsample was contacted at the airport when individuals were about to leave the tourist enclave since landscapes are complex environmental goods we utilize and compare a multiple contingent valuation cv approach with the stated preference approach of contingent ranking the results show that the influence of the consumption experience depends on the valuation method and the consideration of interaction effects in the model the valuation functions were not stable across both sites for most of the models considered and some of the attributes changed their values between the two points of the consumption process interaction effects were more relevant with the contingent ranking model suggesting that cv is a more limited approach in a context of multiple valuation

interpreting suboptimal business outcomes in light of the coase theorem lessons from sidmouth international festival abstract the management team of the world famous sidmouth festival resigned in 2004 after failing to secure bad weather underwriting worth 200 000 and amidst widespread fears that the festival was doomed while claims of a local economic impact of 5 million are seriously flawed it is highly likely that the local economy did benefit by at least several times the amount of the required insurance failure to capture these net positive benefits is linked to ill defined property rights rising transaction costs incomplete information from unreliable sources and actual or feared free riding these conditions prevented the type of efficient bargaining solution in the face of externalities envisioned by the coase theorem practically all of the problems preventing the ideal coasean solution could have been addressed by granting key stakeholders individual ownership rights hence while the coase solution was not applicable the theorem s predictions or its corollary s predictions were confirmed

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

employers discriminatory behavior and the estimation of wage discrimination this paper considers the linkage of empirical estimates of wage discrimination between two groups introduced by oaxaca 1973 to a theoretical model of employers discriminatory behavior it is shown that conditional on different assumptions about employers discriminatory tastes oaxaca s estimators of wage discrimination can be derived that the approach is more generally useful is demonstrated by deriving an alternative estimator of wage discrimination based on the assumption that within each type of labor e g unskilled skilled the utility function capturing employers discriminatory tastes is homogeneous of degree zero with respect to labor inputs from each of the two groups the estimators are compared empirically in an application to male female wage differentials

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

consistent estimates of the impact of special interest groups on economic growth empirical studies designed to testolson s 1982 theory of institutional sclerosis aretypically forced to rely upon proxies to measure theability of special interest groups to engage inredistributive activities which in turn areexpected to hinder economic growth this note showsthat reliance on proxies biases the estimates towardzero here instrumental variable routines areutilized which increase the estimated impact ofspecial interests on the economy

dubious and dubiouser contingent valuation and the time of day we collect contingent valuation data from 524 student survey respondents over a 3 day 72 hour period data analysis of a hypothetical campus referendum focuses on time of day effects on willingness to pay for a renewable energy project we find that subjects responding to the survey during the night time hours i e between 12 a m and 6 a m do not display the law of demand offering theoretically invalid responses to questions with important policy implications results from this research may have serious implications for the contingent valuation method cvm in short just like your father said nothing good happens after midnight when using the cvm jel q51

global corruption and the shadow economy spatial aspects using a large sample of nations this paper examines the relation between corruption and the shadow economy focusing especially on geographic spillovers the results point to complementarity between corruption and the shadow economy we find evidence of own contagion across nations in both corruption and shadow economy activity while cross contagion mostly points to substitution between own shadow economy corruption and neighboring corruption shadow economy these findings are fairly robust across different estimation techniques and measures of the shadow economy

measuring the benefits of local publilc goods environmental quality in gaston county north carolina local governments across the united states have been confronted with a growing range of federal and state mandated environmental protection programmes it is found that an application of contingent valuation to a local environmental policy is internally valid by theoretically and empirically examining the economic determinants of responses to a hypothetical referendum the resulting option price estimate is statistically reliable and has a reasonable order of magnitude results indicate that respondents are willing to pay for improvements in water quality but not air qualilty it is found that informatiion from various external sources helps to explain risk perceptions and these perceptions in turn influence willingness to pay the aggregate benefits of an air and water polllution control programme to gaston county are estimated to be 13 07 million annually with a 90 confidence interval of 11 07 million and 16 12 million

interest group politics and economic growth in the u s states mancur olson s model of economic growth has attracted great attention as a theoretical account of how interest groups influence the rate of economic growth over time moreover the model appears to have received strong empirical support in olson s tests employing u s state data however the specification of the olson construct in these tests is insufficiently attentive to the complex causal chain implicit in olson s argument inadequately accounts for precisely how interest groups matter and employs a static research design that obfuscates the cause and effect relationships posited by the model we review these issues and develop a more complete specification of the olson model the respecified model is then tested using u s state data for the period of the late 1970s and early 1980s using new measures of interest group influence

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

temporal reliability of willingness to pay from the national survey of fishing hunting and wildlife associated recreation the us fish and wildlife service s usfws national survey of fishing hunting and wildlife associated recreation fhwar has been a source of information on wildlife related recreation since 1955 the contingent valuation method has been used to estimate willingness to pay for recreation trips in the 1980 1985 1991 1996 and 2001 surveys however relatively little comparative analysis over time has been performed similar value elicitation formats were used in the 1991 and 1996 surveys for bass and trout fishing deer hunting and nonconsumptive wildlife recreation we statistically analyze these data to assess the temporal reliability of the willingness to pay we control for the effects of trip quality and socioeconomic variables and find that willingness to pay is significantly lower in 1996 for each activity a subtle but important change in the 1996 question format may drive the result of lower willingness to pay 1 a previous version of this article was presented at the 129th annual meeting of

dynamic hypothetical bias in discrete choice experiments evidence from measuring the impact of corporate social responsibility on consumers demand abstract this paper is aimed at studying the dynamics of consumers preferences for corporate social responsibility the data come from both a discrete choice experiment dce and a field experiment conducted in a real market setting the results show that in a static setting first month predictions of a standard dce study and real market shares are statistically similar for the various profiles of corporate social responsibility however as time evolves real market shares present some dynamic patterns that are not mirrored by the standard dce predictions the overall conclusion is that differences between real market behavior and dce data can be attributed to the lack of learning experience or adaptation in dce surveys rather than to the hypothetical nature of the experiments

how sensitive are environmental valuations to economic downturns abstract this paper assesses the temporal stability of willingness to pay estimates wtp under changing economic conditions specifically two questions are addressed a is wtp stable over time and b if it is not are the changes just driven by socio economic effects or something else in order to investigate these questions we used data from the contingent valuation method cvm study conducted after the prestige oil spill in spain in 2006 and a second wave of the same survey repeated in 2009 after spain entered a serious recession median wtp estimates dropped from 60 36 in 2006 to 26 92 in 2009 per household a statistically significant reduction to investigate the amount of the drop in wtp due to observables versus changes in preferences between 2006 and 2009 we use the 2006 logit wtp coefficient estimates with 2009 levels of the independent variables and we obtain a wtp of 46 37 this estimate is statistically different from the 2009 estimate 26 92 in the same fashion by using 2009 logit wtp coefficients with 2006 data we obtain an estimate of 50 29 also different from the 2006 estimate implications of these findings for temporal stability of welfare measures and benefit transfer exercises are also discussed

benefits of participating in contingent valuation mail surveys and their effects on respondent behavior a panel analysis abstract we investigated the fringe benefits of participating in contingent valuation mail surveys and their effects on respondents answers a two wave panel survey evaluating japan s anti global warming policies was conducted one sample was randomly assigned to either of two survey treatment groups with different survey loads factor analyses of answers distinguished the survey fringe benefit factor from the environmental concern factor the correlation between the two factors was smaller for the heavy load group than for the light load group estimations of structural equation models showed that survey participation became higher when the survey fringe benefit factor scored higher this tendency was found regardless of the survey load level structural equation models did not confirm a positive correlation between the survey fringe benefit factor and the consistency of wtp answers across survey waves however a logistic regression of the answers from the heavy load group revealed a positive correlation between the consistency of wtp answers and the level of perception of the survey as a good cause which was highly correlated to the fringe benefit factor in the previous factor analyses this positive relationship was not detected for the light load group

explaining the rain the rise and decline of nations after 25 years in the quarter century since the publication of mancur olson s rise and decline of nations a large literature has evolved testing the central hypothesis regarding olson s thesis on institutional sclerosis these tests have taken the form of both econometric regression analysis involving a sample of various nations and detailed narrative case studies of specific nations tests have appeared in both economics and political science journals as well as in collected volumes and independent books performed primarily by authors from america and europe a review of over 50 separate works reveals that on the whole the theory of institutional sclerosis is generally but certainly not universally supported no systematic bias in favor of or opposition to olson is found to have arisen on the basis of methodology publication outlet or authorship location
