design and analysis of simulated consumer choice or allocation experiments an approach based on aggregate data the authors integrate concepts in conjoint analysis and discrete choice theory in econometrics to develop a new approach to the design and analysis of controlled consumer choice or resource allocat

mexico and the brady plan mexico has throughout the 1980s been centre stage in the debates and events shaping the sovereign debt problem caught between a sudden collapse of its terms of trade and rising world interest rates mexico suspended debt service payments in august 1982 and ushered in what has since become known as the debt crisis in the following years lending to ldcs dried up and debtor countries were increasingly forced to run high trade surpluses to effect ever growing transfers from poor back to rich countries in the face of falling growth rates and rising inflation in the high debt countries then secretary of the treasury baker proposed the baker plan in return for economic reforms high debt countries would get new access to medium term new loans in addition to rolling over of amortization of old loans new loans had to come both from commercial creditors and the official lending institutions with access to capital markets restored the economic reforms would it was hoped allow the debtors to grow out of debt but experience in the high debt countries showed that the original hopes of the proponents of the baker plan went unfulfilled net transfers out of the borrowing countries went up rather than down as

new evidence of the impact of dividend taxation and on the identity of the marginal investor this paper examines the impact of a major change in dividend taxation introduced in the united kingdom in july 1997 the reform was structured in such a way that the immediate impact fell almost entirely on the largest investor class in the united kingdom namely pension funds we find significant changes in the valuation of dividend income after the reform in particular for high yielding companies these results provide strong support for the hypothesis that taxation affects the valua tion of companies and that pension funds were the effective marginal investors for high yielding companies

statistical efficiency of double bounded dichotomous choice contingent valuation the statistical efficiency of conventional dichotomous choice contingent valuation surveys can be improved by asking each respondent a second dichotomous choice question which depends on the response to the first question if the first response is yes the second bid is some amount greater than the first bid while if the first response is no the second bid is some amount smaller this double bounded approach is shown to be asymptotically more efficient than the conventional singlebounded approach using data from a survey of californians regarding their willingness to pay for wetlands in the san joaquin valley we show that in a finite sample the gain in efficiency can be very substantial

ex day behavior with dividend preference and limitations to short term arbitrage the case of swedish lottery bonds abstract swedish lottery bonds offer a unique opportunity to study ex day effects in an environment where cash distributions are tax advantaged relative to capital gains thus in the lottery bond market we observe a reversal of the preference for capital gains that researchers have cited as an explanation for the ex day behavior of u s equities further in this market there are barriers to short term arbitrage when prices do reflect the tax preferences of individual investors we find the bonds are priced around the ex day to reflect differential tax rates on income and capital gains consistent with the prevailing tax regimes the bonds consistently experience negative returns over the coupon payment period and in fact often sell at negative yields prior to the cash distribution as one would expect given tax motivated trading between high tax investors who buy prior to the distribution and low tax investors who buy after the distribution

ex day behavior tax or short term trading effects this study examines the behavior of share prices around the ex dividend dates before and after the introduction of the 1988 income and corporation taxes act that reduced substantially the tax differential between dividends and capital gains in the united kingdom we find that in the pre 1988 period when the differential taxation of dividends and capital gains is high ex day returns are positive and significant in contrast in the post 1988 period ex day returns are in most cases negative and insignificant further analysis reveals that while ex day returns are significantly related to dividend yield and to the length of the settlement period they are not affected by the commonly used measures of transaction costs such as the bid ask spread and trading volume or by the day of week month of the year type of dividend distribution or number of days to the actual receipt of the cash dividend we conclude that taxation affects significantly ex day share prices in the previous studies have documented that the risk adjusted abnormal returns on the ex dividend dates are positive and significantly related to the dividend yield the interpretation of these findings is however controversial the question relates to what category of investors sets ex day prices elton and

integrating methods for ecosystem service assessment and valuation mixed methods or mixed messages a mixed method approach was used to assess and value the ecosystem services derived from the dogger bank an extensive shallow sandbank in the southern north sea three parallel studies were undertaken that 1 identified and quantified where possible how indicators for ecosystem service provision may change according to two future scenarios 2 assessed members of the public s willingness to pay for improvements to a small number of ecosystem services as a consequence of a hypothetical management plan and 3 facilitated a process of deliberation that allowed members of the public to explore the uses of the dogger bank and the conflicts and dilemmas involved in its management each of these studies was designed to answer different and specific research questions and therefore contributes different insights about the ecosystem services delivered by the dogger bank this paper explores what can be gained by bringing these findings together post hoc and the extent to which the different methods are complementary findings suggest that mixed method research brings more understanding than can be gained from the individual approaches alone nevertheless the choice of methods used and how these methods are implemented strongly affects the results obtained

differences between continuous and discrete contingent value estimates in a split sample contingent valuation study of willingness to pay wtp for food safety improvements the dichotomous choice dc elicitation method consistently generated much larger estimates of wtp than did a continuous method little or none of these differences was due to bias introduced by the statistical techniques used with the dc data most or all of the difference was due to differences in respondent behavior in addition the continuous wtp responses showed a significant scope effect while the dc responses did not the observed difference in behavior may be attributable in part to yea saying by dc respondents

a comparison of contingent preference models i compare the informational efficiencies of contingent rating contingent ranking and two contingent paired comparison methods as alternatives to the referendum contingent valuation method the contingent rating method is hypothesized to be most efficient because ratings convey information on preference intensities and can uniquely represent respondent indifference or ambivalence survey data on hunters ratings of alternative hypothetical hunting trips are used to estimate four alternative indirect utility models from which marginal willingness to pay measures for individual trip attributes are derived model comparison wtp estimates and their confidence intervals confirm the relative efficiency of the contingent rating approach

what aspects of formality do workers value evidence from a choice experiment in bangladesh this study uses a choice experiment among 2 000 workers in bangladesh to elicit willingness to pay wtp for job attributes a contract termination notice working hours paid leave and a pension fund using a stated preference method allows calculation of wtp for benefits in this setting despite the lack of data on worker transitions and the fact that many workers are self employed which makes it difficult to use revealed preference methods workers highly value job stability the average worker would be willing to forego a 27 percent increase in income to obtain a 1 year contract relative to no contract or to forego a 12 percent increase to obtain thirty days of termination notice there is substantial heterogeneity in wtp by type of employment and gender women value shorter working hours more than men while government workers place a higher value on contracts than do private sector employees

social costs from proximity to hydraulic fracturing in new york state the study reports data from an economic choice experiment to determine the likely welfare impacts of hydraulic fracturing in this case using natural gas extracted by hydraulic fracturing for household electricity data were collected from an internet survey of 515 residents of new york state the welfare analysis indicated that on average households incur a welfare loss from in state hydraulic fracturing as the source of their electricity the evidence suggests that households in shale counties bear more costs from hf electricity than households out of shale counties the average welfare loss is substantive estimated at 40 46 of average household electric bills in shale counties and 16 20 of bills in counties without shale the evidence also suggests that relative proximity to hf well sites also increases cost borne by households

is individual environmental consciousness one of the determinants in transport mode choice this article models negative impact on the environment as one of the attributes of transport mode by this modelling we are able to examine whether individual environmental consciousness of this impact plays a significant role in his her choice of transport mode a survey data from saito and onohara area in northern osaka of japan is used to estimate the model with the heteroscedastic extreme value specification both of the estimated and simulated results imply that individual environmental consciousness does influence his her decision on transport mode choice in the sample furthermore the likelihood ratio tests indicate that both the utility and scale parameters are not equivalent across sub samples of university commuters research facility commuters and residents the results of the comparison across sub samples suggest that sometimes we may learn more from sub dividing a whole sample into several sub samples if we could distinguish them by their characteristics

women wealth and waterborne disease smallholders willingness to pay for a multiple use water scheme in ethiopia this article identifies factors which contribute to households willingness to pay for improving and protecting a multiple use water scheme in ethiopia it does so through descriptive statistics a probit model and contingent valuation methods complemented with qualitative data estimates suggest farmers willingness to pay is based on gender the prevalence of waterborne disease the time to collect water contact with extension services access to credit level of income and location respondents would pay 3 43 per cent of average income to participate consideration of how gendered norms influence women s access to extension credit and local markets could extend the benefits of such schemes

using labels to investigate scope effects in stated preference methods insufficient sensitivity to scope variations in the scale of the environmental good on offer remains a major criticism of stated preference methods and many studies fail a scope test of some sort across a range of existing explanations for insensitivity to scope commodity mis specification embedding warm glows there seems to exist no clear conclusion on how to deal with the problem this paper provides an alternative explanation for insufficient sensitivity to scope based on re definition of the determinants of value for environmental goods within an attributes based choice model in the proposed framework respondents willingness to pay need depend not only on physical characteristics of a good but may also depend on the label under which the environmental good is sold in the hypothetical market to investigate this problem a choice experiment study of biodiversity was conducted we find that controlling for the effects of a label in this case national park designation leads to significant increase in the scope sensitivity of welfare measures

accounting for local impacts of photovoltaic farms the application of two stated preferences approaches to a case study in portugal abstract renewable energy sources for electricity generation are unequivocally more environmentally friendly than the traditional sources but are not impact free given the potential for solar photovoltaic energy to contribute to the energy mix in some countries it is timely to carefully consider the potential environmental costs of operation of photovoltaic farms which are experienced by the local population while the general benefits accrue to all we apply the contingent valuation method to a sample of local residents close to three selected photovoltaic farms in portugal also we design a discrete choice experiment to elicit the valuation of specific adverse impacts of electricity generation through photovoltaic energy by national residents our results show that the value elicited in the vicinity of the photovoltaic farms is non negligible on the other hand national residents ponder the trade offs implied by the choice sets and value positively the different adverse local impacts both of these estimates in conjunction or independently can be used to fully account for this often neglected cost of solar energy furthermore we argue that when studying the public acceptance of renewables using stated preference methods explicitly presents the trade offs between negative impacts and costs contributing to more realistic portrayal of public opinion

are citizens willing to pay for agricultural multifunctionality agricultural multifunctionality is the recognition of the joint exercise of economic environmental and social functions by the agricultural sector in order to make the concept operative for the design of public policies it is necessary to estimate the social demand for such functions the main objective of this article is to present an empirical application in this sense for this purpose we have adopted the agricultural system of cereal steppes in tierra de campos in spain as a case study the economic valuation technique used is the choice experiment the results suggest the existence of a significant demand for the different functions although the demand is heterogeneous depending on the socioeconomic characteristics of the individuals surveyed

ex dividend day stock price behavior the case of the 1986 tax reform act this paper analyzes the behavior of stock prices around ex dividend days after the implementation of the 1986 tax reform act that dramatically reduced the difference between the tax treatment of realized long term capital gains and dividend income in 1987 and completely eliminated the differential in 1988 we show that this tax change had no effect on the ex dividend stock price behavior which is consistent with the hypothesis that long term individual investors have no significant effect on ex day stock prices during this time period the results indicate that the activity of short term traders and corporate traders dominates the price determination on the ex day

the effect of taxes on the relative valuation of dividends and capital gains evidence from dual class british investment trusts we provide evidence that taxes affect equity valuation by studying british investment trusts having otherwise identical classes of cash and stock dividend paying shares outstanding we study 1969 1982 a period in which there were two dramatic changes in tax policy we find that stock dividend shares which are convertible into cash dividend shares sell at premiums when the tax system favors capital gains and at discounts when the tax advantage of capital gains is reduced after the 1975 elimination of the tax advantage to stock dividend shares we observe that investors convert virtually all stock dividend shares into cash dividend shares the possible existence of tax related dividend clienteles remains a controversy long 1978 poterba 1986 and bailey 1988 study firms with two classes of shares one class paying stock dividends and the other paying cash dividends for evidence of these clienteles and their effects on equity valuation the evidence from these studies is mixed long finds evidence supporting an investor preference for cash dividends over capital gains while poterba and bailey find no evidence of a preference for cash dividends we provide additional evidence on tax clienteles and their effects on equity valuation by studying twelve british investment trusts having one class of shares entitled only to stock dividends or scrip dividends the british term and another class entitled only to cash dividends our study of dual class british investment trusts provides unique insights

new evidence that taxes affect the valuation of dividends this paper uses british data to examine the effects of dividend taxes on investors relative valuation of dividends and capital gains british data offer great potential to illuminate the dividends and taxes question since there have been two radical changes and several minor reforms in british dividend tax policy during the last 30 years studying the relationship between dividends and stock price movements during different tax regimes offers an ideal controlled experiment for assessing the effects of taxes on investors valuation of dividends using daily data on a small sample of firms and monthly data on a much broader sample we find clear evidence that taxes affect the equilibrium relationship between dividend yields and market returns these findings suggest that taxes are important determinants of security market equilibrium and deepen the puzzle of why firms pay dividends financial economists have long been puzzled by corporate dividend behavior many individual investors should value a dollar of corporate dividends less than a dollar of corporate retentions because the former gives rise to greater tax liabilities corporations however face equal costs of paying out dividends and retaining earnings miller and modigliani 31 demonstrated that in the absence of taxes dividend policy should have no effect on share valuation if dividends are tax penalized however a value maximizing firm should pay no dividends widespread dividend payments to taxable investors are therefore surprising in 1981 dividend tax revenues in the united states were estimated to exceed 20 billion dollars indeed some have interpreted the large volume of dividends paid as evidence against the rational behavior postulates typically used by economists the dividend question has stimulated a large theoretical and empirical literature concerned with the qluestion of investors valuation of dividends in particular the question of how taxes affect the market valuation of dividends has generated considerable controversy numerous studies including auerbach 2 litzenberger and ramaswamy 24 26 morgan 34 and rosenberg and marathe

corporate tax policy under the labour government 1997 2010 this paper reviews and evaluates corporate tax policy under the 1997 2010 labour government during this period the government implemented a classical rate cut cum base broadening tax policy for large companies tax policy for small and medium sized enterprises smes is more difficult to characterize in the first two terms rates were cut more frequently than for large businesses and the base was narrowed but in the government s third term statutory rates for smes were increased extensive reforms of dividends and capital gains tax at the individual and corporate level have also been implemented in 1998 the imputation system was abolished and in 2009 foreign dividends became exempt for corporate income tax purposes a comparison of the statutory and effective rates shows that the uk has lost some ground to the oecd since 2003 4 fundamental reforms of dividends and capital gains taxation have aligned the uk to its competitors and to eu law we find that the overall effect of the labour s tax policy on aggregate investment may have been small for three reasons increases in real investment between 1997 and 2007 are largely explained by the economic cycle while the reduction in the tax component of the user cost of capital was small moreover the increase in aggregate investment was led by an exceptional surge in investment in structures driven by a real estate boom finally we note that most investment was undertaken by large companies and therefore it was not affected by the large set of tax reforms focusing on smes

low investment and large ldc debt in the 1980s this paper aims at disentangling the correlation between ldc debt and investment in the 1980s the author shows that a large debt was not an unconditional predictor of low investment in the 1980s nor was investment abnormally low when compared to a financial autarky rate calculated in the text he does find however that the actual service of the debt crowded out investment for the rescheduling countries he shows that 1 percent of gdp paid abroad reduced domestic investment by 0 3 percent of gdp this is identical to the correlation between investment and foreign finance observed in the 1960s copyright 1993 by american economic association

transferring economic values on the basis of an ecological classification of nature abstract in order to save research costs economists often try to transfer the economic value of existing nature areas to other planned areas because the existing area and the plan area are not similar such benefit transfers are generally not considered valid although some economists have paid attention to the ecological characteristics of sites in relation to transfers they do not seem to have decomposed ecosystems into spatially homogeneous units which are similar at different locations since ecologists have developed classifications of homogeneous units it is investigated whether it is possible to determine economic values for the elements of an ecological classification of nature which can be transferred from one location to another this investigation is conducted on the basis empirical data collected by means of a cvm survey at different nature reserves on the dutch coast the results indicate that the use of an ecological classification may offer economists new opportunities for transferring economic benefits within a limited geographical area

the debt tax shield in general equilibrium abstract we study the general equilibrium effects of the corporate debt tax shield in an endowment economy with a redistributive tax system that taxes firm profits and household income and redistributes tax revenues in an attempt to harmonize households lifetime consumption opportunities in general equilibrium the debt tax shield not only affects corporate capital structure and valuation but also causes poorer households to consume more and save less at a younger age without the debt tax shield the same welfare improvements for poorer households are achievable with significantly lower tax rates

ex dividend returns the mexican puzzle abstract we study ex dividend returns in mexico where an imputation system entitles individual investors to a net dividend tax credit based on taxation we expect ex day abnormal returns to be negative or at most zero in mexico however they are significantly positive because ex day returns are positive even for stocks restricted to mexican nationals they are not attributable to foreign stockholders tax considerations none of the market microstructure based hypothesis in the literature can explain these positive ex day returns ex day returns in mexico are a puzzle

did the debt crisis cause the investment crisis there is now a large literature that attributes the investment decline in heavily indebted countries to the effects of the international debt crisis which began in 1982 however these countries also faced falling export prices and high world real interest rates in the early 1980s and these shocks could have directly caused investment to decline one way to test for debt effects is to see whether equations without any debt related information can nevertheless forecast the investment declines that these countries experienced this paper shows that such equations can forecast investment in many indebted countries and thus casts doubt on many debt related explanations for the investment declines

do personal taxes affect capital structure evidence from the 2003 tax cut abstract because the personal tax treatments of interest and dividend income likely affect the relative cost of debt and equity financing a sharp change in tax treatment could affect firms optimal leverage this paper examines the effect of the 2003 equity income tax cut on firms debt usage because this tax cut affected only individual investors we can use a difference in differences method to identify the effect of personal tax on firms leverage previous research has found that the 2003 tax cut encouraged dividend payouts and reduced the cost of equity but it provides no link to equilibrium leverage ratios we estimate that the tax cut causes the affected firms leverage to decrease by about 5 percentage points furthermore we show that the effects of the tax cut are stronger for firms with lower marginal corporate tax rates and for firms that are not financially constrained consistent with our theoretical predictions overall we find strong evidence that personal tax is an important determinant of firms optimal leverage

reconsidering heterogeneity and aggregation issues in environmental valuation a multi attribute approach the economic valuation of complex environmental goods composed of multiple attributes is an expanding field of research in ecological and environmental economics however several issues are still subjects of debate this paper focuses on three of them the linearity of the valuation function in the attributes aggregation criteria for obtaining social values and the heterogeneity of individuals utility functions a methodological approach based on multi attribute utility theory which enables us to contrast the impact of these concerns on the valuation of environmental goods is proposed we employ the methodology to value a protected natural area and from the results obtained we can conclude that the non linearity and the heterogeneity of the individual utility function are relevant aspects of environmental valuation that need to be taken into account when valuing environmental goods

perceptions versus objective measures of environmental quality in combined revealed and stated preference models of environmental valuation abstract this study examines perceptions and objective attribute measures in discrete choice models of recreation site choice behavior these forms of attribute measurement are examined in individual and combined revealed preference stated preference models our results suggest that the model based on perceptions slightly outperforms the models based on objective attribute measures however issues such as the definition of the choice set and the measurement of welfare present significant challenges when using perceptions data

willingness to accept compensation for the environmental risks of oil transport on the amazon a choice modeling experiment abstract this paper looks at the question of whether subsistence level indigenous people place a value on the preservation of ecosystems independent of direct impacts of environmental change such as impacts on their production activities the economics literature generally suggests that non use values don t exist among the poor and in the informal sector of the economy we examine this issue through a choice modeling experiment a survey was conducted of rainforest communities who live on the banks of the amazon river rio solimoes in the vicinity of proposed oil and gas pipelines the data were analyzed in the choice modeling framework revealing relatively high amounts of compensation that were necessary in order to accept the potential ecosystem damages associated with oil transport even if the people were completely compensated for direct damages such as loss of access to productive resources these results suggest that environmental quality is important for its own sake a result that is very different from the implicit assumption among many economists

do hypothetical and actual marginal willingness to pay differ in choice experiments application to the valuation of the environment abstract in this paper we test the validity of choice experiments with donations for environmental projects in particular we test whether or not there are differences in preferences between a hypothetical and an actual choice experiment our experiments indicate no differences in addition internal tests of validity indicate transitive and stable preferences in both experiments although there are some indications of possible learning effects during the experiment

why do stock prices drop by less than the value of the dividend evidence from a country without taxes abstract it is well documented that stock prices on ex dividend days drop by less than the value of the dividend on average this has commonly been attributed to the effect of tax clienteles we examine data from the hong kong stock market where neither dividends nor capital gains are taxed as in the u s the average stock price drop is less than the value of the dividend specifically the average dividend for the period 1980 1993 is hk 0 12 and the average price drop is hk 0 06 we are able to account for this both theoretically and empirically through market microstructure arguments

low energy efficiency in rental properties asymmetric information or low willingness to pay abstract asymmetric information may explain low energy efficiency in rented properties energy ratings while a solution to the information problem will only lead to higher efficiency levels if renter s willingness to pay wtp exceeds landlord s investment costs using a sample of renters from one university this paper estimates this wtp using a discrete choice experiment where respondents choose from a hypothetical set of single bedroom apartments that differ according to a number of attributes including the energy rating results show that there is a strong disutility associated with the least efficient properties and that renters will pay significantly more for efficiency improvements at the lower end of the efficiency scale importantly our wtp estimates are calculated in a setting where respondents were informed about the energy rating system prior to choosing and where the rating was shown for every property therefore in order to maximise the impact of energy rating systems policymakers are encouraged to ensure that both these informational characteristics are in place

marginal stockholder tax effects and ex dividend day price behavior evidence from taxable versus nontaxable closed end funds almost all research on the movement of stock prices on ex dividend days has found that prices decline by less than the dividend though this is consistent with tax effects several papers have argued that this phenomenon could be caused by market microstructure effects in this paper we make use of a natural experiment that provides support for the tax explanations of ex dividend behavior some closed end funds have taxable and some have nontaxable dividend distributions both types are subject to taxes on capital gains the implication of this for ex dividendday price behavior is very different between these two types of funds if taxes matter this paper demonstrates that the direction of ex dividendday price behavior is consistent with a tax explanation and that ex dividend day price behavior changes as theory would suggest with changes in the tax law

using choice experiments to value the environment this paper we outline the choice experiment approach to environmental valuation this approach has its roots in lancaster s characteristics theory of value in random utility theory and in experimental design we show how marginal values for the attributes of environmental assets such as forests and rivers can be estimated from pair wise choices as well as the value of the environmental asset as a whole these choice pairs are designed so as to allow efficient statistical estimation of the underlying utility function and to minimise required sample size choice experiments have important advantages over other environmental valuation methods such as contingent valuation and travel cost type models although many design issues remain unresolved applications to environmental issues have so far been relatively limited we illustrate the use of choice experiments with reference to a recent uk study on public preferences for alternative forest landscapes this study allows us to perform a convergent validity test on the choice experiment estimates of willingness to pay

options taxes and ex dividend day behavior a novel way of estimating the expected as opposed to the actual share price fall off is developed using option prices this method is applied to the uk traded options market using data from 1979 to 1984 the results show that a the average expected fall off implicit in option prices is around 55 to 60 of the dividend and significantly different from it the fall off also varied inversely with the dividend yield which is consistent with the prediction of the tax clientele hypothesis b the estimates of the expected fall off were not significantly different from the actual fall off c finally the results imply that the usual assumption made in valuing options on dividend paying stocks that the fall off is equal to the dividend would lead to downward biased estimates of the option value

entrepreneurship in and around institutional voids a case study from bangladesh abstract in many developing countries those living in poverty are unable to participate in markets due to the weakness or complete absence of supportive institutions this study examines in microcosm such institutional voids and illustrates the activities of an entrepreneurial actor in rural bangladesh aimed at addressing them the findings enable us to better understand why institutional voids originate and to unpack institutional processes in a setting characterized by extreme resource constraints and an institutional fabric that is rich but often at odds with market development we depict the crafting of new institutional arrangements as an ongoing process of bricolage and unveil its political nature as well as its potentially negative consequences

tax induced trading around ex dividend days abstract this paper investigates trading volume around ex dividend days for taxable distributions cash dividends it is found that trading volume increases significantly around the ex dividend day this increase is more pronounced for high yield actively traded stocks and after brokerage commissions became negotiable the results are consistent with the hypothesis that short term traders have an impact on ex day price behavior at least for taxable distributions for non taxable distributions stock splits and stock dividends we find negative abnormal volume around ex day

tax reform and ex dividend day behavior this paper investigates the effect of a major canadian tax reform on the ex dividend day behavior of companies on the toronto stock exchange the results are inconsistent with the hypothesis that price changes on ex dividend days reflect the relative taxation of dividends and capital gains for the representative investor but are consistent with the hypothesis that ex dividend day price behavior reflects short term trading activities

using choice experiments to investigate the policy relevance of heterogeneity in farmer agri environmental contract preferences agri environmental contracts are used to provide incentives for nature management on private land in e g the european union the aim of this article is to investigate preference heterogeneity for agri environmental contracts among farmers in order to discuss potential policy improvements utilising heterogeneity we used a choice experiment to elicit farmers stated preferences for afforestation contracts four attributes are investigated purpose of afforestation option of cancelling the contract monitoring and compensation level all attributes present a potential conflict between farmers and authorities interests which emphasises the importance of knowing how to handle these interests a random parameter logit model shows that having the option to cancel the contract decreases farmers required compensation level and monitoring increases it furthermore farmers are willing to accept a lower compensation when the aim is to protect biodiversity and ground water relative to recreation latent class models with class probability variables reveal discrete heterogeneity and support a division into four groups with divergent preferences for example a group of farmers who already have forest areas does not find the option of cancelling the contract important whereas another group relying on the farm for income requires higher compensation the findings indicate potential for efficiency gains from targeting the contracts

using conjoint analysis to derive estimates of compensating variation abstract we use several approaches to derive estimates of hicksian compensating variation from conjoint ratings data the different estimation approaches produced mixed results with respect to consistency with utility theory statistical significance of key variables magnitude of welfare estimates and confidence bounds on welfare estimates these findings suggest conjoint analyses are not a panacea for the problems being debated regarding contingent valuation and travel cost methodologies and conjoint questions appear to share many of the advantages and disadvantages associated with dichotomous choice contingent valuation questions

ex dividend price behavior of common stocks this study examines common stock prices around ex dividend dates such price data usually contain a mixture of observations some with and some without arbitrageurs and or dividend capturers active our theory predicts that such mixing will result in a nonlinear relation between percentage price drop and dividend yield not the commonly assumed linear relation this prediction and another important prediction of theory are supported empirically in a variety of tests marginal price drop is not significantly different from the dividend amount thus over the last several decades one for one marginal price drop has been an excellent average rule of thumb article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

valuing financial health and environmental benefits of bt cotton in pakistan data from a farm survey and choice experiment are used to value the benefits of bt cotton in pakistan unlike previous research on the economic impacts of bt which mostly concentrated on financial benefits in terms of gross margins we also quantify and monetize positive externalities associated with technology adoption due to lower chemical pesticide use on bt cotton plots there are significant health advantages in terms of reduced incidence of acute pesticide poisoning and environmental advantages in terms of higher biodiversity and lower soil and groundwater contamination these positive externalities are valued at us 79 per acre of which half is attributable to health and the other half to environmental improvements adding average gross margin gains of us 204 results in an aggregate benefit of us 283 per acre of bt or us 1 7 billion for the total bt cotton area in pakistan

ex dividend day trading who how and why evidence from the finnish market abstract this study examines the ex dividend day trading behavior of all investors in the finnish stock market consistent with dynamic dividend clientele theories investors with a preference for dividend income buy shares cum dividend and sell ex dividend the reverse is true for investors with the opposite preference investors also engage in overnight arbitrage earning on average a 2 overnight return on their invested capital trades at the investor level reveal that idiosyncratic risk is an important determinant in the choice of stock for short term ex day trading furthermore transaction costs and dividend yield jointly determine whether the volume of short term trading activity is nonzero

altruism spillovers are behaviors in context free experiments predictive of altruism toward a naturally occurring public good abstract this paper addresses the external validity of experiments investigating the characteristics of altruism in the voluntary provision of public goods we conduct two related experiments that allow us to examine whether individuals who act more altruistically in the context free environment are also more likely to act altruistically toward a naturally occurring public good we find that laboratory behavior can be predictive of contributions toward naturally occurring goods but not in a uniform way in fact parametric measures of altruism do a poor job of predicting which subjects are most likely to contribute to a naturally occurring public good

integrated assessment of sustainability trade offs and pathways for global bioenergy production framing a novel hybrid approach abstract current controversies and debates on bioenergy production in the areas of greenhouse gases emission reduction food and energy security social exclusion and welfare erosion and ecosystem deterioration attest to the challenges which the bioenergy sector has to overcome to achieve its global production potentials because it is yet an evolving sector the sustainability of bioenergy production in different regions is very elusive experiences show that bioenergy policies in one region can have impacts not only on its own but also on other regions social economic and ecological sustainability it is thus important to assess development pathways for bioenergy to exploit the potential benefits and forestall any unnecessary costs this paper frames a novel hybrid approach for assessing bioenergy potentials for regions with diverging economic social and ecological systems the approach is based on a conceptual framework that takes into account trade offs decisions on sustainability goals and production options in the assessment of bioenergy pathways it combines different empirical techniques for the systematic investigation of trade offs and pathways including fuzzy logic conjoint logit and path analyses to show the relevance and utility of these techniques for the integrated assessment of trade offs and pathways in bioenergy development we illustrated their application using results and data from previous related studies

the impact of choice inconsistencies in stated choice studies a new test procedure revealing mutuallyinconsistent choices has been developed andapplied to stated choice data our analysisshows that inconsistent choices commonly occurin several stated choice tasks an applicationof the test to the norwegian value of timestudy data shows that failing to excludeinconsistent choices resulted in asubstantially higher value of time theinconsistent choices were made by less educatedparticipants as the tasks were undertaken inthe easy context of choosing travelalternatives with three attributes practitioners of more complex and cognitivedemanding designs should be particularilyconcerned with these results

a comparison of stated preference methods for environmental valuation this paper presents an empirical comparison of contingent valuation cvm and choice experiments which are used to value environmental quality changes both of these methods require individuals to state their preferences for environmental qualities however choice experiments differ from cvm in that environmental attributes are varied in an experimental design which requires respondents to make repeated choices between bundles of attributes the empirical application involved the effect of environmental quality changes arising from forest management practices on recreational moose hunting values significant differences were found between the values derived from the two methods however detailed examination of the implied choice behaviour suggested that respondents ignored substitute recreation areas in the cvm question restricting the choice experiment model to consider only the one site where quality was varied resulted in welfare estimates similar to the cvm model this highlights the importance of substitutes in environmental valuation and suggests that choice experiments may be more appropriate than cvm in some cases
