peer group formation in an adverse selection model this paper develops an adverse selection model where peer group systems are shown to trigger lower interest rates and remove credit rationing in the case where borrowers are uninformed about their potential partners and ex post state verification or auditing by banks is costly peer group formation reduces interest rates due to a collateral effect namely cross subsidisation amongst borrowers acts as collateral behind a loan by uncovering such a collateral effect this paper shows that peer group systems can be viewed as an effective risk pooling mechanism and thus enhance efficiency notjust in the full information set up a well known family of adverse selection models in the stiglitz and weiss 1981 tradition demonstrates that when banks are imperfectly informed about the riskiness of borrowers projects and therefore cannot discriminate against risky borrowers interest rates become inefficiently high and worthy borrowers are driven out of the credit market the extent of this problem is substantially magnified when borrowers do not have adequate collateral to secure a loan typically adverse selection combined with lack of collateral leads to prohibitively high interest rates poorly endowed individuals e g students immigrants the unemployed and a vast majority of poor individuals in developing countries often face such high rates and therefore cannot take advantage of profitable investment opportunities a peer group formation system represents a possible solution to the above problem under this system a bank lends to borrowers without collateral on condition that the borrowers organise themselves into groups and that participant borrowers within each group accept to take joint responsibility for a loan thus in addition to repaying their own share of the loan each group member must accept to repay the obligations of their defaulting peers otherwise the entire group is denied access to future refinancing systems of this kind have been very successful in practice they have generated lower interest rates for the rural poor in for example bangladesh the philippines bolivia and the state of arkansas in the united states moreover group lending has also been successfully implemented in large urban areas such in the cities of dhaka and chicago 1

the commons as a natural barrier to entry why there are so few fish farms a competitive industry which overuses a common access resource may create a barrier to entry similar to spence s example of a cartel that uses excess capacity to prevent entry in most industries when a new firm enters existing firms find that their demand curves have fallen so they reduce their output to accommodate the new entrant in spence s model the cartel disintegrates upon entry so that the output of existing firms increases which may make entry unprofitable in an open access fishery the supply curve bends backward thus a fall in price created by the entry of a fish farm increases rather than decreases supply in the backwardbending portion of the supply curve an important implication of this theory is that fish farms are more likely to be unprofitable the more heavily overharvested is a species in a common property competitive market this natural barrier to entry may explain why true mariculture is barely in its infancy bardach ryther and mclarney

revealed objective functions of microfinance institutions evidence from bangladesh abstract this paper discerns between two alternative objective functions for not for profit microfinance institutions mfis profit maximization and poverty targeting i use the strategic branch location choices of the two largest mfis in a mature concentrated market to reveal their objectives i consider location decisions to be the pure strategy nash equilibrium outcome of a one shot game where the mfis simultaneously choose markets in which to locate as well as how many branches to open in each applying the duality principle i nest fully a pure profit maximization objective within a poverty targeting motive i test the model using comprehensive data from bangladesh in 2003 structurally estimating profit and impact functions my msm estimates suggest that pure profit maximization cannot explain the branch placement pattern for grameen bank or brac they both deviate towards poverty alleviation targeting one higher standard deviation of poverty headcount costs grameen 35 2 of its potential profits and brac 51 4

competition and microfinance abstract competition between microfinance institutions mfis in developing countries has increased dramatically in the last decade we model the behavior of non profit lenders and show that their non standard client maximizing objectives cause them to cross subsidize within their pool of borrowers thus when competition eliminates rents on profitable borrowers it is likely to yield a new equilibrium in which poor borrowers are worse off as competition exacerbates asymmetric information problems over borrower indebtedness the most impatient borrowers begin to obtain multiple loans creating a negative externality that leads to less favorable equilibrium loan contracts for all borrowers

the microfinance promise in the past decade microfinance programs have demonstrated that it is possible to lend to low income households while maintaining high repayment rates even without requiring collateral the programs promise a revolution in approaches to alleviating poverty and spreading financial services and millions of poor households are served globally a growing body of economic theory demonstrates how new contractual forms offer a key to microfinance success particularly the use of group lending contracts with joint liability for the most part however high repayment rates have not translated into profits and studies of impacts on poverty yield a mixed picture in describing emerging tensions the paper highlights the diversity of innovative mechanisms beyond group lending contracts the measurement of financial sustainability the estimation of economic and social impacts the costs and benefits of subsidization and the potential to reduce poverty through savings programs rather than just credit the promise of microfinance has pushed far ahead of the evidence and an agenda is put forward for addressing critical empirical gaps and sharpening the terms of policy discussion

preferences for environmental quality under uncertainty abstract although the expected effects of environmental policies and interventions are rarely known with certainty stated preference surveys rarely elicit preferences over uncertain environmental outcomes this article presents empirical results challenging the view that ignoring such uncertainty during preference elicitation is of no consequence so long as people only care about final environmental states we show that measured preferences for final environmental states water quality in this case depend on whether people choose between final states or between lotteries over final states in contrast to the typical finding for monetary lotteries we find significant under weighting of low probability events related to water quality

the economics of wildlife farming and endangered species conservation abstract there is growing concern that the traditional protectionist approach to conservation is expensive and insufficient to deliver the desired environmental outcomes supply side policies to conserve endangered species have drawn support by generating supplies from captive bred animals wildlife commodity prices are expected to fall thereby lowering the incentive to poach species in the wild supply side policies however often neglect the institutional framework within which the wildlife trade takes place and ignore the potential strategic responses of economic agents adopting a model that captures imperfect competition between traders and farmers we analyze the effect of supply side policies and conclude that under some circumstances these policies may contribute to further devastation of wild stocks we derive conditions under which captive breeding contributes to conservation and discuss implications for policy makers

who benefits the interactional determinants of microfinance s varied effects abstractsince its emergence as a development tool scholars and practitioners have questioned microfinance s short and long term impacts but have had insufficient empirical evidence to assess them to address this gap this paper draws on mixed method research to assess the effects of microfinance loan and educational services over time it explores why even within the same microfinance institution mfi some borrowers benefit from microfinance services more than others in the short term and examines how this translates into long term impacts the article identifies understudied sources of intra group variation the diversity and choices of borrowers and mfi employees interacting with each other and their broader contexts

optimal contracts with public ex post information abstract we are concerned with the value of public ex post information about a seller s costs to an initially uninformed buyer we derive necessary and sufficient conditions for a public ex post signal s s that is correlated with the risk neutral seller s costs to render the initial information asymmetry inconsequential to the buyer the first best outcome for the buyer is shown to be feasible if 1 the dimension of s is at least that of or 2 the conditional likelihood function of s given is for one of its realizations sj a strictly increasing function of and more concave in than is the seller s cost function

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

targeting the poor using community information abstract governments and aid agencies target transfers to the poor but audits to deter the rich are costly this paper analyzes how community information can improve targeting if each community is given a hard budget constraint then targeting costs can be substantially reduced by asking recipients to make reports about each other audits are threatened in the event of a disagreement but never carried out in equilibrium this scheme is immune to collusion

modeling loss aversion and reference dependence effects on brand choice based upon a recently developed multiattribute generalization of prospect theory s value function tversky and kahneman 1991 we argue that consumer choice is influenced by the position of brands relative to multiattribute reference points and that consumers weigh losses from a reference point more than equivalent sized gains loss aversion we sketch implications of this model for understanding brand choice we develop a multinomial logit formulation of a reference dependent choice model calibrating it using scanner data in addition to providing better fit in both estimation and forecast periods than a standard multinomial logit model the model s coefficients demonstrate significant loss aversion as hypothesized we also discuss the implications of a reference dependent view of consumer choice for modeling brand choice demonstrate that loss aversion can account for asymmetric responses to changes in product characteristics and examine other implications for competitive strategy

the commercialization of the microfinance industry is there a personal mission drift among credit officers recent research suggests that many microfinance institutions increasingly focus on financial performance at the expense of the social component of their dual objectives existing studies typically assume that capital providers and managers mainly drive this so called mission drift in this study we investigate whether personal mission drift at the credit officer level can further explain the reduced emphasis on poorer clients among microfinance institutions we present both qualitative and quantitative evidence that more experienced credit officers tend to serve fewer vulnerable clients specifically we show that all else being equal credit officer experience is negatively correlated with the provision of small loans loans to young clients and loans to clients with disabilities our qualitative analysis suggests that perceived client risk and preferences for increased time efficiency mainly drive more experienced credit officers relative neglect of more vulnerable clients this drift appears to be reinforced by the industry s incentive schemes therefore credit officer incentives and training should be designed to prevent this mission drift which is observed at the microfinance institution level but is actually initiated at the credit officer level

gender biases in bank lending lessons from microcredit in france the evidence on gender discrimination in lending remains controversial to capture gender biases in banks loan allocations we observe the impact on the applicants of a microfinance institution mfi and exploit the natural experiment of a regulatory change imposing a strict eur 10 000 loan ceiling on microcredit descriptive statistics indicate that the presence of the ceiling is associated both with bank mfi co financing and with harsher treatment of female borrowers to investigate causal links we develop an econometric approach that addresses the concerns of selection biases multicollinearity and endogeneity our empirical findings suggest that the change in the mfi s gender related attitude was triggered by banks through co financing hence we speculate that co financing pushes ceiling constrained mfis to import whatever biases in loan granting that the banks are prone to overall this paper stresses that apparently benign regulations such as loan ceilings can significantly harm the women s empowerment efforts made by mfis

the use of village agents in rural credit delivery using a simple principal agent model this article examines the incentive problems that arise when a formal financial institution such as a rural bank utilises a member of the rural community to act as an agent in screening potential borrowers and collecting repayment optimal compensation schemes are derived for the agent and their implications are discussed in addition i show that the norms and rules that govern village life may aid the financial institution by helping to constrain possible strategic behaviour by the agent

do respondents adjust their expected utility in the presence of an outcome certainty attribute in a choice experiment in a stated preference valuation survey the expected benefits of environmental policies are generally presented to respondents without reference to the fact that the predicted outcomes are rarely known with certainty this omission may reduce the credibility of the valuation scenario and contribute to hypothetical bias in the study outlined in this paper a choice experiment was conducted to elicit values for environmental improvements in the great barrier reef australia with outcome certainty included as a separate attribute different specifications of the utility functions which imply different behavioural assumptions about the way choices have been made generate variations in value estimates results showed that respondents incorporate outcome certainty into their decisions but that an expected utility formulation represented by the interaction between environmental protection and likelihood of occurrence underestimated environmental values some environmental protection values appear to be independent of outcome certainty which may be consistent with existence values and other non use categories a partial expected utility model is cautiously recommended

impact of cultured shrimp industry on wild shrimp fisheries analysis of price determination mechanisms and market dynamics cultured shrimp production has been growing dramatically on the world market over the last 15 years and some of the farm raised species are now considered as price indicators on the main market places one may therefore expect the price of theses cultured shrimp to have an impact on the price formation of other species and especially on wild shrimp with which they compete in this paper the authors address this question in the case of the wild shrimp penaeus subtilis exploited by the french guyana fishery south america and competing on the french market with the cultured thai shrimp back tiger a series of econometric tests issued from the co integration theory is performed between the price series of the two products these tests indicate that the two series are co integrated and that the black tiger market acts as a market leader for the french guyana shrimp product the authors then discuss the reasons of the current predominance of farm raised shrimp on wild caught product and in particular the french guyana shrimp and identify the constraints that the french market demand induces on both producers and importers in the light of this analysis a commercial strategy that would mitigate the impact of the thai shrimp on the french guyana product is suggested

decision making over time and under uncertainty a common approach this paper considers a number of parallels between risky and intertemporal choice we begin by demonstrating a one to one correspondence between the behavioral violations of the respective normative theories for the two domains i e expected utility and discounted utility models we argue that such violations or preference reversals are broadly consistent with three propositions about the weight that an attribute receives in both types of multiattribute choice specifically it appears that 1 if we add a constant to all values of an attribute then that attribute becomes less important 2 if we proportionately increase all values of an attribute or if we change the sign of an attribute from positive to negative then that attribute becomes more important the generality of these propositions as well as the constraints they would impose on separable representations of multiattribute preferences is discussed

depth of outreach and financial sustainability of microfinance institutions the primary justification for subsidizing microfinance institutions mfis is their enhancement of social welfare by extending credit to the poor households therefore recent emphasis on their financial self sufficiency has created concern that this may adversely affect the mission of social outreach utilizing data from 702 mfis operating in 83 countries this study shows empirical evidence of a positive complementary relationship between financial sustainability and depth of outreach

willingness to pay for agricultural land preservation and policy process attributes does the method matter this article examines relationships between willingness to pay for land preservation and policy process attributes the approach departs from traditional welfare assessments in that it does not constrain attributes of the policy process to be utility neutral results indicate policy process attributes may influence utility in some circumstances even after controlling for the influence of land use outcomes often correlated with specific policy techniques results further imply that in some cases even comprehensive specification of land use outcomes by stated preference instruments may be insufficient to prevent systematic shifts in willingness to pay related to unspecified yet assumed policy process attributes

technology and the future bioeconomy new discoveries in life sciences and the challenge of climate change are leading to the emergence of the bioeconomy where basic methods of advanced biology are applied to produce a wide array of products while also improving environmental quality the emergence of the bioeconomy is a continuing evolutionary process of transition from systems of mining nonrenewable resources to farming renewable ones this transition benefits from the modern tools of molecular biology that have expanded the human capacity to breed new organisms and utilize them to increase productivity in agriculture and fisheries as well as produce a wide array of products that were extracted in the past this transition is leading to the integration of the agricultural sector with the energy and mineral sectors the introduction of biotechnology has already improved the productivity of medicine as well as agriculture but in the case of agriculture has encountered resistance and regulatory constraints the evolution of the bioeconomy requires continuous public investment in research and innovation as well as the establishment of a regulatory framework and financial incentives and institutions that would lead to continuous private sector investment in the development and commercialization of new products one of the biggest challenges is the development of a regulatory framework that would control possible human and environmental externalities from new biotechnology products and at the same time not stifle innovation jel classifications q1 q2 q3 q4 q5

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

microfinance and dynamic incentives dynamic incentives where incentives to repay are generated by granting access to future loans is one of the methodologies used by microfinance institutions mfis in this paper i present a model of dynamic incentives where lenders are uncertain over how much borrowers value future loans loan terms are determined endogenously and loans become more favorable as the probability of default becomes lower i show that in all equilibria but one all borrowers default including the most patient ones i then compare equilibria with and without double dipping i show that when credit constrained borrowers have access to multiple loans equilibrium loan terms have to become more favorable to overcome increased gains from default if borrower s access to multiple loans is unforseen by lenders then the default rates go up in the short run finally if lenders use group loans it generates endogenous hyperbolic discounting even though the borrowers are exponential discounters

an open access fishery with rational expectations explain the evolution of the fish stock and the boat fleet as well as determine their equilibrium levels 2 while the changes in the fish stock are described by a biological rule entry and exit from the fishing industry are determined by how expectations are formed we examine a general model in which entry and exit are proportional to the present value of expected profits and compare two special cases of adaptive myopic expectations and rational expectations although both expectations mechanisms lead to the same equilibrium values they lead to different adjustment paths where expectations solely depend on current values myopic expectations it is well known that boats enter the fishery only when the fish stock is greater than its steady state stock 3 with rational expectations however boats may enter when the fish stock is much lower than its steady state value provided the boat fleet is sufficiently small this difference in adjustment is observable and in principle leads to an obvious test on how agents form expectations section 2 develops a general dynamic model for studying fisheries in section 3 we show that the model standardly used in the literature is equivalent to a myopic adaptive expectations model a rational expectations model is analyzed in section 4 the standard and rational expectations models are compared in section 5 section 6 illustrates this comparison using a simulation based on a schaefer model of the pacific halibut fishery section 7 presents the conclusions

thy neighbor s keeper the design of a credit cooperative with theory and a test economists now appreciate that resource allocation in less economically developed economies is profoundly influenced by non firm economic institutions however our theories of non firm institutions often suggest different answers to many questions including those of policy this paper illustrates a method for discriminating between alternative theories using data from german credit cooperatives from the nineteenth and early twentieth century germany we build a model of credit cooperatives designed to provide monitoring incentives and test this using nineteenth century data authors

outreach sustainability and leverage in monitored and peer monitored lending abstract i study the contract design problem facing microfinance lending organizations mfos that want to maximize the impact and outreach of their lending activities to a target population of poor borrowers while remaining financially sustainable tradeoffs between outreach sustainability and financial leverage are shaped by the endogenous monitoring and delegation costs that arise within a chain of agency relationships subject to moral hazard between borrowers loan staff mfo equity owners and outside investors all else equal sustainable mfos that target poorer borrowers must charge higher interest rates have higher staff costs per dollar loaned and are less leveraged analysis of data for 72 mfos tends to support the findings

policies and impact an analysis of village level microfinance institutions this paper uses variation in policies and institutional characteristics to evaluate the impacts of village level microfinance institutions in rural thailand to identify impacts we use policies related to the successful unsuccessful provision of services as exogenous variation in effective financial intermediation we find that institutions particularly those with good policies can promote asset growth consumption smoothing and occupational mobility and can decrease moneylender reliance specifically cash lending institutions production credit groups and especially women s groups are successful in providing intermediation and its benefits to members while buffalo banks and rice banks are not the policies identified as important to intermediation and benefits the provision of savings services especially pledged savings accounts emergency services and training and advice surprisingly much publicized policies such as joint liability default consequences or repayment frequency had no measured impacts jel 012 016

willingness to pay for emissions reduction application of choice modeling under uncertainty and different management options abstract this paper presents the results of a choice modeling survey of households in queensland australia to assess values for reductions in national greenhouse emissions by 2020 the study is novel in two main ways first labeled alternatives were used to assess whether the types of management options for reducing net emissions green power energy efficient technologies or carbon capture are significant in understanding preferences for reducing emissions second the importance of the level and type of uncertainty involved in reductions is tested the types of uncertainty include 1 the uncertainty of achieving emissions reduction and 2 the uncertainty of international participation as the percentage of total global emissions covered by international agreements the results of this survey identified how choice responses vary when the level of uncertainty associated with emissions reduction options is included within choice alternatives

how rising competition among microfinance institutions affects incumbent lenders this article uses data from uganda s largest incumbent microfinance institution to analyse the impact of entry by competing lenders on client behaviour we observe that rising competition does not lead to an increase in client dropout rate but induces a decline in repayment performance and savings deposited with the incumbent suggesting rising multiple loan taking by clients this joint effect on dropout and repayment is consistent with some negative information about clients and is being shared across lenders however the observed decline in repayment rates in a context of rising multiple loan taking shows that information sharing about clients is far from complete

policy v individual heterogeneity in the benefits of climate change mitigation evidence from a stated preference survey abstract we use stated preference methods to investigate the public s preferences for decarbonization policies we ask three research questions first does the willingness to pay wtp for each ton of co2 emissions reductions depend on the policies and on individual characteristics of the respondents second how extensive is the variation associated with these factors third what factors affect support for or opposition to a carbon tax based on the responses to discrete choice experiments from a sample of italians we find that the wtp per ton of co2 ranges between zero and 230 the variation associated with the policy instrument is approximately of the same order of magnitude as that associated with individual characteristics of the respondents

competition and incentives with motivated agents a unifying theme in the literature on organizations such as public bureaucracies and private nonprofits is the importance of mission as opposed to profit as an organizational goal such mission oriented organizations are frequently staffed by motivated agents who subscribe to the mission this paper studies incentives in such contexts and emphasizes the role of matching the mission preferences of principals and agents in increasing organizational efficiency matching economizes on the need for high powered incentives it can also however entrench bureaucratic conservatism and resistance to innovations the framework developed in this paper is applied to school competition incentives in the public sector and in private nonprofits and the interdependence of incentives and productivity between the private for profit sector and the mission oriented sector through occupational choice jel d23 d73 h41 l31 the late twentieth century witnessed a historic high in the march of market capitalism with unbridled optimism in the role of the profit motive in promoting welfare in the production of private goods moreover this generated a broad consensus on the optimal organization of private good production through privately owned competitive firms when it comes to the provision of collective goods no such consensus has emerged debates about the relative merits of public and private provision still dominate this paper suggests a contracting approach to the provision of collective goods it focuses on two key issues how to structure incentives and the role of competition between providers at its heart is the idea that organizations that provide collective goods cohere around a mission 2 thus production of collective goods can be viewed as mission oriented

the role of economics in climate change policy many policy problems have frustratingly long histories of inefficient regulation that can be difficult or impossible to reverse even where large efficiency gains might be had from doing so climate change is an exception however because little real action has been undertaken to date it presents an unusual opportunity for an efficient economic policy to be employed right from the beginning however the opportunity could easily be lost ongoing negotiations conducted under the auspices of the united nations framework convention on climate change have so far produced the kyoto protocol a deeply flawed agreement that manages to be both economically inefficient and politically impractical in this article we examine the key economic characteristics of climate change and argue that economic theory provides good guidance on the design of an efficient and politically realistic policy because climate change involves vast uncertainties and has potentially enormous distributional effects neither of the standard market based environmental policy instruments is a viable approach a tradable permit system would be inefficient and an emissions tax would be politically unrealistic however a hybrid policy combining the best features of the two would be an efficient and practical approach we then compare our hybrid proposal to the kyoto protocol and argue that it overcomes the protocol s shortcomings

repayment performance in group based credit programs in bangladesh an empirical analysis abstract this paper analyzes the repayment rates of 128 credit groups belonging to three group based credit programs in bangladesh the association for social advancement asa the bangladesh rural advancement committee brac and the rangpur dinajpur rural service rdrs using tobit analysis specific tests are performed on the following hypothesized determinants group size size of loans degree of loan rationing enterprise mix within groups demographic characteristics social ties and status and occurrence of idiosyncratic shocks the paper concludes that if basic principles of prudential banking are adhered to repayment rates can be good even in poor and remote communities the important thing for financial institutions is to tailor services such that it becomes worthwhile for the poor to establish a profitable long term association in addition more freedom to members in the process of group formation is recommended

adding value to randomization with qualitative analysis the case of microcredit in rural morocco this paper analyzes microcredit demand and use to draw lessons on how households appropriate microcredit services it introduces qualitative analysis to a randomized study findings suggest that microcredit demand and use is shaped not only by agro ecological conditions but by two major partially interrelated factors debt related norms articulated with the perception of the sanction in case of repayment default and the social life of microcredit namely how social actors credit officers and local leaders engage with microcredit on a conceptual perspective we argue that microcredit markets do not result from supply confronting demand but instead are historical political and social constructs

a test of policy labels in environmental choice modelling studies abstract a question that arises in the application of environmental choice modelling cm studies is whether to present the choice sets in a generic or labelled form the former involves labelling the policy options to be presented to respondents in a generic way for example as option a option b etc the labelled approach assigns alternative specific descriptors to each option these may relate to the names of proposed policies different locations or any other policy relevant details both approaches have their advantages a potential advantage of using alternative specific labels is that respondents may be better able to base their choices on the true policy context this can increase predictive validity whilst at the same time reducing the cognitive burden of the cm exercise a potential advantage of the generic labelling approach is that respondents may be less inclined to base their choices wholly or largely on the labels and as a consequence may provide better information regarding trade offs among attributes the two approaches to choice set design are compared in the context of a cm study of the values of remnant vegetation in the desert uplands of central queensland results indicate a difference in the cognitive processes generated by choice models using the different approaches this difference is reflected in both the alternative specific constants and the taste parameters and cannot be accounted for by differences in error variance across the two treatments the implications for environmental valuation are discussed

mission drift and ethical crisis in microfinance institutions what matters abstract in recent years financial interests have increasingly influenced microfinance institutions mfis with financial gain overshadowing service to the poor this phenomenon which we can term mission drift has caused apprehension among academicians as well as policy makers for its negation of the fundamental social ethos of mfis and the mandate of sustainable financial inclusion hence this study aims to identify the factors of mission drift with special emphasis on the role of funding sources we collect data from a sample of 169 mfis in bangladesh from the period of 2009 2014 and deploy static and dynamic panel data estimation techniques the results suggest that commercial fund is susceptible to mission drift as average loan size over gni per capita increases when mfis use more commercial fund in their operation the finding also revealed that when mfis focus more on commercial interest return on assets and operational sustainability they tend to depart further from the original aim of serving the poorest of the poor the findings further suggest that mission drift is influenced by other factors such as macroeconomic conditions and regulatory environment this study underscores the importance for policy to ensure that poor people have viable access to financial services from mfis toward promoting long term sustainable development

alternative australian climate change plans the public s views climate change has come to the forefront of australian politics and there is now an active on going policy debate about how to best reach a commonly agreed long term goal this paper looks at five major dimensions of this debate and constructs policy options based on them a discrete choice experiment approach was used with a representative sample from a major internet panel provider survey respondents made choices between pairs of policy options with different characteristics they favored policies starting in 2010 rather than 2012 and spending 20 of revenue raised on energy related r d they were almost evenly split on whether the plan should initially exempt the transport sector and two competing approaches that redistribute revenue from the plan and they opposed plans giving special treatment to energy intensive sectors of the economy a number of other policy relevant questions related to understanding australian views and knowledge related to climate change also were asked

the influence of task complexity on consumer choice a latent class model of decision strategy switching the literature indicating that person context and task specific factors cause consumers to utilize different decision strategies has generally failed to affect the specification of choice models used by practitioners and academics alike who still tend to assume an utility maximizing omniscient indefatigable consumer this article 1 introduces decision strategy selection within a maintained compensatory framework into aggregate choice models via latent classes which arise because of task complexity 2 it demonstrates that within an experimental choice task the model reflects changing aggregate preferences as choice complexity changes and as the task progresses the import of these findings for current practice model interpretation and future research needs is examined

recreation demand models with taste differences over people we estimate random parameter logit models of anglers choice of fishing site the models generalize logit by allowing coefficients to vary randomly over anglers rather than being fixed the models do not exhibit the restrictive independence from irrelevant alternatives property of logit and can represent any substitution pattern estimation explicitly accounts for the fact that the variation in coefficients over anglers induces correlation in unobserved utility over trips by the same angler willingness to pay for improved fish stock and the value to anglers of specific sites are calculated from the models and compared with the estimates obtained from a standard logit model

group lending local information and peer selection this paper analyzes how group lending programs use joint liability to utilize local information that borrowers have about each other s projects through self selection of group members in the group formation stage these schemes are shown to lead to positive assortative matching in group formation faced with the same contract this makes the effective cost of borrowing lower to safer borrowers because they have safer partners conditional on success their expected dues to the lender are lower than that of riskier borrowers the resulting improvement in the pool of borrowers is shown to increase repayment rates and welfare q 1999 elsevier science b v all rights reserved

designing credit agent incentives to prevent mission drift in pro poor microfinance institutions abstract credit agents in microfinance institutions mfis must be given incentives to acquire information on potential borrowers and select them in accordance with the mfi s objectives we show that while giving incentives has no cost in for profit mfis it is costly in pro poor mfis when repayment and wealth are positively correlated a pro poor mfi cannot obtain the selection of poor clients in the proportion it wishes with incentives based solely on repayment it then becomes necessary to audit the share of very poor borrowers selected by an agent in order to provide the latter with adequate incentives when audit costs are large pro poor mfis may have to forego selection on wealth and use other targeting devices such as working in impoverished geographical locations driven by donor concerns with mission drift away from the poor audits on the wealth status of clients have been introduced at the level of mfis we show that introducing pro poor incentives requires extending such audits to the level of credit agents

full extraction of the surplus in bayesian and dominant strategy auctions we consider auctions for a single indivisible object in the case where the bidders have information about each other which is not available to the seller we show that the seller can use this information to his own benefit and we completely characterize the environ ments in which a well chosen auction gives him the same expected payoff as that obtainable were he able to sell the object with full information about each bidder s willingness to pay we provide this characterization for auctions in which the bidders have dominant strate gies and for those where the relevant equilibrium concept is bayesian nash in both set ups the existence of these auctions hinges on the possibility of constructing lotteries with the correct properties we consider the situation in which an agent the seller possesses one indivisible unit of a good to which he attaches no value but the good has value to a number of potential buyers and its transfer to one of them would increase social welfare in particular the transfer to the buyer with the highest valuation maximizes social welfare in this paper we completely characterize environments in which the seller can design an auction that will enable him to capture for himself the full increase in social welfare induced by the transfer of the good to the bidder with the highest willingness to pay if the seller had full information about the reservation prices of potential buyers his optimal selling strategy would be very simple he would announce a price equal or very close to the highest reservation value the optimal strategy for the bidder with the highest evaluation would be to accept the offer note that we are treating a situation in which the seller can commit himself to a price as a result of the exchange the utility of the seller increases by the full amount of the increase in social welfare and he has been able to fully extract the surplus in many circumstances however a seller has only imperfect knowledge of the buyers willingnesses to pay in this case he must find some mechanism or auction which will enable him to maximize his benefit from the sale of the object the auction literature starts with this observation and shows how the seller can by an astute choice of auction extract the largest possible fraction of the surplus in general the literature has shown that this proportion is strictly less than one in some circumstances the bidders will have information about each other which is not available to the seller for instance in auctions for petroleum drilling rights bidders know the results of geological tests which they have

subjectivity in credit allocation to micro entrepreneurs evidence from brazil this paper estimates the impact of loan officer subjectivity on microcredit granting by exploiting an exceptionally detailed database from a brazilian microfinance institution the loan officers collect field data meet with applicants and make recommendations to the credit committee which has the final say on both loan approval and loan size ls the loan officer s subjectivity is captured through gender bias our estimations indeed show subjective gender gap in ls this gap is almost exclusively attributable to loan officers we interpret this finding as evidence that despite monitoring and wage incentivization microcredit officers let their subjective preferences interfere with loan granting we conclude by suggesting alternative means to curb subjectivity in credit allocation to micro entrepreneurs

screening by the company you keep joint liability lending and the peer selection effect we look at an economic environment where borrowers have some information about the nature of each other s projects that lenders do not we show that joint liability lending contracts similar to those used by credit cooperatives and group lending schemes will induce endogenous peer selection in the formation of groups in a way that the instrument of joint liability can be used as a screening device to exploit this local information this can improve welfare and repayment rates if standard screening instruments such as collateral are unavailable

framing decisions in uncertain scenarios an analysis of tourist preferences in the face of global warming abstract this paper presents the results of a choice experiment survey of tourists in mallorca spain to elicit preferences for designed policies aimed at addressing the attractiveness losses of the destination in the face of global warming the study is novel in two main ways first it introduces the uncertainty deriving from the stochastic nature of global warming not as a policy attribute but as an inherent feature of the valuation scenario for this reason the expected temperature change and its probability of occurrence were kept constant across alternatives but not across different choice tasks second it measures the willingness to pay for a set of pro environmental policies under different framings results show that the inclusion of uncertainty shapes individuals decisions

willingness to pay and policy instrument choice for climate change policy in the united states abstract this paper provides the first willingness to pay wtp estimates in support of a national climate change policy that are comparable with the costs of actual legislative efforts in the u s congress based on a survey of 2034 american adults we find that households are on average willing to pay between 79 and 89 per year in support of reducing domestic greenhouse gas ghg emissions 17 by 2020 even very conservative estimates yield an average wtp at or above 60 per year taking advantage of randomized treatments within the survey valuation question we find that mean wtp does not vary substantially among the policy instruments of a cap and trade program a carbon tax or a ghg regulation but there are differences in the sociodemographic characteristics of those willing to pay across policy instruments greater education always increases wtp older individuals have a lower wtp for a carbon tax and a ghg regulation while greater household income increases wtp for these same two policy instruments republicans along with those indicating no political party affiliation have a significantly lower wtp regardless of the policy instrument but many of these differences are no longer evident after controlling for respondent opinions about whether global warming is actually happening
