hot stuff index insurance for indian pepper growers summary we simulate the impact of a joint price and yield index insurance on the basis of a small representative panel data set of indian smallholder pepper growers affordable and feasible index insurance reduces crop revenue risk to around 68 of its original level while a reduction to 50 of this level can be achieved with ideal insurance basis risk is large for only a small fraction of farm households depending on risk aversion 5 30 of farm households is willing to pay for index insurance increasing to 12 50 with a 50 premium reduction opportunity costs of consumption smoothing in the form of lower productivity levels suggest potential welfare gains of specialization with insurance

the neoclassical advent american economics at the dawn of the 20th century for the u s economy the last quarter of the 19th century brought the closing of the western frontier agricultural hardship in the south the rise of large corporations and trusts and the emergence of a serious labor movement the fledgling american economics profession struggled to document and prescribe for the confounding mix of industrialization urbanization and rural crisis in 1900 the relatively small community of serious economic researchers focused on applied issues in public policy and industrial organization the prominent institutionalist school strongly influenced by the almost millennial theories of the social gospel movement emphasized the inequities of the emerging economy and looked forward to a new more cooperative system of production on the eve of the 20th century john bates clark published in 1899 the distribution of wealth a theory of wages interest and profit with this volume neoclassicism matured into a major intellectual force within american economic thought with clark as its defining figure clark s analytical approach and his normative purposes hardly went unchallenged moreover the great majority of economists in the united states continued to work in the institutionalist vein up to world war ii nevertheless by viewing the american neoclassical advent in the context of its own time we can gain a deeper understanding of both american economics at the turn of the 20th century and the early character of the school that came to dominate our discipline

behavioural development economics lessons from field labs in the developing world abstract explanations of poverty growth and development depend on the assumptions made about individual preferences and the willingness to engage in strategic behaviour economic experiments especially those conducted in the field have begun to paint a picture of economic agents in developing communities that is at variance with the traditional portrait we review this growing literature with an eye towards preference related experiments conducted in the field we also offer lessons on what development economists might learn from experiments we conclude by sharing our thoughts on how to conduct experiments in the field and then offer a few ideas for future research

semi nonparametric distribution free dichotomous choice contingent valuation abstract we apply a semi nonparametric distribution free estimator for binary discrete response data to the estimation of a dichotomous choice contingent valuation model using this estimator mean and median compensating and equivalent variation can be consistently estimated without making nontheoretically motivated assumptions on consumer preferences the approach is illustrated using a contingent valuation survey of willingness to pay for reduction of risk of premature death due to exposure to hazardous waste we find that a conventional parametric estimator and the proposed estimator give similar estimates of unconditional wtp but that conditional on explanatory variables the estimates are quite different

estimating local welfare generated by an nfl team under credible threat of relocation this study offers the opportunity to examine the welfare contribution of the minnesota vikings to minnesota households in the context of a credible threat of team relocation we find the credibility of the threat of relocation is essential to providing unbiased estimates of welfare this study utilizes contingent valuation methodology cvm and a random utility model rum to analyze minnesotans decision making mechanisms for supporting a new stadium initiative while previous studies have attempted to measure the welfare associated with a sports franchise we develop and discuss bias that may be imparted to estimates when the researcher fails to calculate a choke price further we develop an unbiased approach to identify welfare when respondents perceive a risk of losing the franchise the range of welfare contribution by the vikings to households in minnesota is 445 3 million to 1 571 3 million according to a 95 confidence interval based on our study

unequal treatment of identical agents in cournot equilibrium oligopoly models where prior actions by firms affect subsequent marginal costs have been useful in illuminating policy debates in areas such as antitrust regulation environmental protection and international competition we discuss properties of such models when a cournot equilibrium occurs at the second stage aggregate production costs strictly decline with no change in gross revenue or gross consumer surplus if the prior actions strictly increase the variance of marginal costs without changing the marginal cost sum therefore unless the cost of inducing second stage asymmetry more than offsets this reduction in production costs the private and social optima are asymmetric

sports jobs and taxes the economic impact of sports teams and stadiums this book examines the economic impact of new stadiums or a sports franchise on the local economy it explores such general issues as the appropriate method for measuring economic benefits and costs the source of the bargaining power of teams in obtaining subsidies from local government the local politics of attracting and retaining teams the relationship between sports and local employment and the importance of stadium design in influencing the economic effects of a facility the book also contains case studies of major league sports facilities in baltimore chicago cincinnati cleveland indianapolis san francisco and the twin cities and of minor league baseball stadiums and spring training facilities the primary conclusions are the sports teams and stadiums are not a source of local economic growth and employment the size of the net subsidy exceeds the financial benefit of a new stadium and cities are probably willing to subsidize sports teams because of the intense popularity of sports among a substantial proportion of voters and businesses and the leverage that teams enjoy from the monopoly position of professional sports leagues

horizontal mergers with free entry abstract we consider the impact of horizontal mergers in the presence of free entry and exit in contrast to much of the previous literature on mergers our model yields predictions that seem intuitively reasonable with only moderate cost synergies mergers of a small number of industry participants are beneficial even under quantity competition there is no free rider problem in that insiders always benefit more than outsiders and quantity setting and price setting games yield similar predictions about profitability we also derive two welfare results that hold under quantity competition with homogeneous goods if the initial no merger equilibrium is symmetric then with free entry 1 a horizontal merger has no impact on the equilibrium price and 2 all privately beneficial mergers are socially beneficial

reference dependent preferences team relocations and major league expansion abstract professional sports teams receive large subsidies some in excess of 500 million from local governments for the construction of new facilities these subsidies cannot be explained by tangible economic benefits and estimates of the value of intangible benefits also fall short of typical subsidies in this paper we incorporate fans reference dependent preferences into a model of the bargaining between local governments and teams the model predicts that teams use relocation threats to exploit fans utility loss from team departures a negative deviation from the status quo to extract large subsidies from local governments fans loss aversion provides an explanation of the current team distribution and observed team relocation and league expansion decisions in north america the model also highlights the importance of anti trust exemptions of the leagues in creating credible relocation threats for existing teams

optimal bid selection for dichotomous choice contingent valuation surveys abstract this paper develops a model for optimal survey design for the dichotomous choice contingent valuation method that finds the bid amounts as well as the sample sizes corresponding to each bid the model uses an iterative procedure to select the survey design that minimizes the mean square error of the welfare measure a set of monte carlo simulations shows that the model produces significantly lower mean squared errors for the welfare estimate than the next best model produces survey design under alternative assumptions regarding the statistical distribution of the welfare measure is also addressed the model produced significantly different survey designs depending on whether the distribution was assumed to be symmetric or asymmetric

agency theory and franchising some empirical results this article provides an empirical assessment of various agency theoretic explanations for franchising including risk sharing one sided moral hazard and two sided moral hazard the empirical models use proxies for factors such as risk moral hazard and franchisors need for capital to explain both franchisors decisions about the terms of their contracts royalty rates and up front franchise fees and the extent to which they use franchising in this article i exploit several new sources of data on franchising to construct a cross section of 548 franchisors involved in various business activities in the united states in 1986 the data are most consistent with a model based on two sided moral hazard the empirical models are also more successful at explaining the extent to which franchisors choose to franchise stores than at explaining the terms of franchise contracts finally contrary to the predictions of several theoretical models i find that royalty rates and franchise fees are not negatively related

exhaustible resources and the dynamics of comparative advantage abstract this paper analyses the role of international differences in factor endowments and rates of time preference in determining the pattern of trade and specialization when one of the factors of production is an exhaustible resource the length of the period over which a country exports the resource is found to be directly related to the fraction of the world s resource stock under its control while the relative endowments of the inexhaustible factor influence only the volume of trade the direction of trade is determined by the rates of time preference with the more impatient country being the first to export the resource effects of trade on factor rewards are also examined

consumption benefits of national hockey league game trips estimated from revealed and stated preference demand data this paper examines the demand for hockey game trips among metropolitan and nonmetropolitan residents of alberta canada using data on both revealed and stated preference game trip behavior from a telephone survey conducted throughout alberta we estimate the effect of ticket prices team quality arena amenities and capacity on the latent demand for national hockey league hockey games we nd that lower ticket prices higher team quality and additional capacity encourage attendance in the status quo scenario consumer surplus per game is 50 for those who had attended hockey games and about 50 less for those who had not attended games exploiting the stated preference data we develop a number of other consumer surplus estimates we also include travel costs in the estimation of the demand function and estimate the full value of the game trip considering both ticket prices and travel costs sold out arenas in calgary and edmonton generate annual consumption bene ts of 40 and 35 million when only ticket prices are used to calculate consumer surplus i e excluding travel costs considering the full price consumer surplus for the calgary flames of 103 per game trip the annual consumption bene ts may be as high as 82 million jel r22 l83 d61

multidivisional firms internal competition and the merger paradox traditional modelling of mergers has the merged firms insiders cooperate and maximize joint profits this approach has several unappealing results in quantity setting games for example mergers typically are not profitable for insiders but are profitable for non merging firms outsiders we take a different approach and allow for a parent company that can play each insider off one another in quantity setting games with our approach mergers are profitable for insiders unprofitable for outsiders socially beneficial and involve in a non monopolizing merger a small number of firms finally we find that the optimal strategy depends on whether firms compete in quantity or prices jel classification l000 entreprises multi divisionnelles concurrence interne et le paradoxe des fusions les modelisations conventionnelles des fusions suggerent que les entreprises fusionnees parties prenantes cooperent et maximisent leurs profits conjoints cette approche engendre plusieurs resultats contre intuitifs dans des jeux de concurrence par les quantites i e les fusions en general ne sont pas profitables pour les parties prenantes mais sont profitables pour des entreprises qui ne sont pas fusionnees les autres les auteurs adoptent une approche differente qui permet a l entreprise mere de jouer les parties prenantes l une contre l autre dans ce genre de jeu avec l approche adoptee les fusions sont profitables pour les parties prenantes non profitables pour les autres socialement benefiques et impliquent un petit nombre d entreprises dans une fusion qui ne cree pas un monopole finalement on trouve que la strategie optimale depend fondamentalement du fait que les entreprises se concurrencent par les prix ou par les quantites

cooperative r d and strategic trade policy in this paper three different cooperative r d arrangements in a strategic trade policy model are examined a policy game between two governments is analysed where each government chooses a particular cooperative r d policy in order to maximize national welfare allowing cooperation in r d is also compared with the use of r d subsidies it is jointly optimal for both governments to allow their firms to participate in the same type of cooperative r d and allowing cooperation in r d can

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

the limits of monopolization through acquisition we address the question of whether competitive acquisition of firms by their rivals can result in complete or partial monopolization of a homogeneous product industry this question is modeled in terms of two distinct three stage noncoopera tive games analysis of subgame perfect pure strategy nash equilibria of these games discloses that under simplifying assumptions monopolization of an industry through acquisition is limited to industries with relatively few firms partial monopolization is either limited in scope or can be completely eliminated by prohibiting any owner from acquiring over 50 percent of the firms in the industry

patterns of rainfall insurance participation in rural india take up of an innovative rainfall insurance policy offered to smallholder farmers in rural india decreases with basis risk between insurance payouts and income fluctuations increases with household wealth and decreases with binding credit constraints these results are consistent with the predictions of a simple neoclassical model with borrowing constraints other patterns are less consistent with the benchmark model for example participation in village networks and measures of familiarity with the insurance vendor are strongly correlated with insurance take up decisions and risk averse households are less not more likely to purchase insurance these results may reflect household uncertainty about the product given their limited experience with it

selling the game estimating the economic impact of professional sports through taxable sales sports leagues franchises and civic boosters tout the economic benefits of professional sports as an incentive for host cities to construct new stadiums or arenas at considerable public expense past league sponsored studies have estimated that new stadiums franchises and mega events such as the super bowl increase economic activity by potentially hundreds of millions of dollars in host cities a detailed regression analysis of taxable sales in florida over the period extending from 1980 to 2005 fails to support these claims new stadiums arenas and franchises as well as mega events appear to be as likely to reduce taxable sales as increase them similarly strikes and lockouts in professional sports have not systematically lead to reductions in local taxable sales

universal health insurance in the clinton plan coverage as a tax financed public good the financing arrangements embodied in the clinton health reform plan involve some important differences in the way in which public goods are usually financed the subsidies to small low wage firms mandated to provide benefits distort markets in both labor and products and offer incentives for the creation of small firms in addition the financing scheme implicitly envisions a head tax on families at modest income levels but offers a possible rationale for it nevertheless the main reason for many of the financing features appears to be an attempt to hold down the apparent budgetary cost of universal coverage

price vs weather shock hedging for cash crops ex ante evaluation for cotton producers in cameroon abstract in the sudano sahelian zone which includes northern cameroon the inter annual variability of the rainy season is high and irrigation scarce as a consequence bad rainy seasons have a detrimental impact on crop yield in this paper we assess the risk mitigation capacity of weather index based insurance for cotton farmers we compare the ability of various indices mainly based on daily rainfall to increase the expected utility of a representative risk averse farmer we first give a tractable definition of basis risk and use it to show that weather index based insurance is associated with a large basis risk whatever the index considered it has thus limited potential for income smoothing a conclusion which is robust to the utility function second in accordance with the existing agronomical literature we find that the length of the cotton growing cycle in days is the best performing index considered third we show that using observed cotton sowing dates to define the length of the growing cycle significantly decreases the basis risk compared to using simulated sowing dates finally we find that the gain of the weather index based insurance is lower than that of hedging against cotton price fluctuations provided by the national cotton company this casts doubt on the strategy of supporting weather index insurances in cash crop sectors selling at international market prices without recommending any price stabilisation scheme

on optimal capacity expansion for domestic processing of an exhaustible natural resource abstract the issue of optimal capacity expansion for domestic processing of exhaustible natural resource exports in a small open economy is analyzed in the context of non malleable capital a complete qualitative characterization of the optimal dynamic paths for resource extraction domestic processing and capacity expansion is obtained it is shown that the presence of capital stock adjustment costs which vary directly with the rate of capacity expansion in the resource processing sector implies a presumption in favor of a policy of domestic processing and that the optimal pattern of capacity expansion is of the front end loading variety

welfare measurements using contingent valuation a comparison of techniques three commonly used techniques of asking contingent valuation questions are compared iterative bidding payment cards and dichotomous choice the results reveal that no single contingent valuation technique is neutral in the elicitation of hicksian surplus and each technique has its strengths and weaknesses the iterative bidding estimates contain a starting point bias while the payment card and dichotomous choice estimates were influenced by the interviewers soliciting the contingent values finally the analysis of dichotomous choice responses involves unresolved issues that warrant further investigation on the other hand dichotomous choice is the easiest technique to administer in a survey setting

insurance credit and technology adoption field experimental evidence from malawi this brief summarizes the insurance credit and technology adoption field experimental evidence from malawi the farmers were offered loans for the november 2006 planting season does production risk suppress the demand for credit the author implemented a randomized field experiment to ask whether provision of insurance against a major source of production risk induces farmers to take out loans to adopt a new crop technology the study sample was composed of roughly 800 maize and groundnut farmers in malawi where by far the dominant source of production risk is the level of rainfall the author randomly selected half of the farmers to be offered credit to purchase high yielding hybrid maize and groundnut seeds for planting in the november 2006 crop season the other half of farmers were offered a similar credit package but were also required to purchase at actuarially fair rates a weather insurance policy that partially or fully forgave the loan in the event of poor rainfall surprisingly take up was lower by 13 percentage points among farmers offered insurance with the loan take up was 33 0 percent for farmers who were offered the uninsured loan there is suggestive evidence that reduced take up of the insured loan was due to farmers already having implicit insurance from the limited liability clause in the loan contract insured loan take up was positively correlated with farmer education income and wealth which may proxy for the individual s default costs by contrast take up of the uninsured loan was uncorrelated with these farmer characteristics

union bargaining power subcontracting and innovation we show that if a firm can subcontract production to an informal sector an increase in union power may either increase or decrease innovation an increase in union power makes the firm worse off irrespective of its effect on innovation however in contrast to the usual belief an increase in union power may increase consumer surplus and decrease union utility by affecting innovation thus suggesting that a union may not want to be too powerful an increase in union power may create an ambiguous effect on social welfare our analysis provides new insights to the relation between union power and innovation

rent extracting tariffs and the management of exhaustible resources this paper examines the interaction between a resource exporting and a resource importing country the exporting country must choose the optimal rate of depletion of an exhaustible resource and also must decide on the allocation of the extracted resource between exports and domestic use optimal management from a national point of view entails inefficiency from a global perspective in that too little resource is exported as the supplying country exploits its monopoly power the importing country however has an incentive to extract some of the resource rent by using a tariff although rent extraction is limited by the exporter s ability to use the resource domestically the optimal tariff is positive and induces greater overall inefficiency

optimal experimental design for double bounded dichotomous choice contingent valuation the double bounded dichotomous choice model is becoming popular in the contingent valuation literature this technique considers the responses to two bids the second one being determined according to the response to the first and it has been shown to be statistically more efficient than the standard single bounded model in this paper the issue of the optimal choice of bid values for the double bounded logit model is addressed these designs are derived to satisfy the d optimal c optimal and fiducial method criteria

optimal designs for discrete choice contingent valuation surveys single bound double bound and bivariate models this paper finds the designs for discrete choice contingent valuation surveys which maximize the precision of a statistic of interest about the public s willingness to pay wtp for a change in the environmental quality such as median wtp an optimization problem is set up in which the efficiency of the estimate of median wtp or a related concept is the objective function to optimize with respect to the survey design i e the set of bids offered to the respondents in deriving the optimal designs we consider alternative econometric models such as the basic single bound model that uses the responses to the first payment question the traditional interval data or double bound model for surveys with a follow up payment question and the recently proposed bivariate binary response model simulations are carried out to compare the alternative design principles and assess their performances with respect to the statistic of primary interest median wtp and other welfare measures such as mean wtp other designs that are constructed ad hoc are also examined

divisionalization franchising and divestiture incentives in oligopoly a two stage game is used to model firms strategic incentives to divide production among autonomous competing units through divisionalization franchising or divestiture firms simultaneously choose their number of competing units which then engage in cournot competition while it is costly to form autonomous units each firm does so in equilibrium thus reducing firm profits and increasing social welfare relative to the case where firms cannot form competing units with linear demand and costs duopolists choose the socially optimal number of competing units oligopolies with larger numbers of firms choose too many the case of nonlinear demand is also examined copyright 1996 by american economic association

retail contracting theory and practice we summarize a number of regularities that arise in the empirical literature on contractual relationships between manufacturers and their exclusive resellers we do this using studies of traditional and business format franchise relationships as well as studies of salesforce integration decisions some of the patterns that we uncover are consistent with a standard incentive cum insurance theory of organization while others are not we brie y review some theoretical extensions that seem promising in terms of reconciling seeming con icts between theory and practice i introduction manufacturers of retail products must decide whether to sell their products to consumers themselves vertical integration or to sell via independent retailers vertical separation when manufacturers do not perform the sales function internally but want exclusive retailers they usually choose some form of franchising 1 many theories attempt to explain the choice of retail organizational form moreover a considerable body of empirical evidence concerning this choice is accumulating we attempt to evaluate this econometric evidence and relate it to the theories to accomplish this task we assess studies of franchising arrangements as well as studies of sales force organization in industrial settings the paper is organized as follows in the next section we highlight a number of regularities that arise in the empirical literature on retail contracting in particular we nd that i risk is positively related to the use of high powered incentives vertical separation ii the importance of the agent s eiort in production is positively related to the use of high powered incentives

internal decision making rules and collusion we study the impact of internal decision making structures on the stability of collusive agreements to this end we use a three firm spatial competition model where two firms belong to the same holding company the holding company can decide to set prices itself or to delegate this decision to its local units it is shown that when transportation costs are high collusion is more stable under delegation furthermore collusion with maximum prices is more profitable if price setting is delegated to the local units profitability is reversed for low discount factors

a dynamic game of a transboundary pollutant with asymmetric players abstract modeling transboundary pollutants in a dynamic game framework provides a foundation for analyzing the impact of various policy options the focus of this analysis is on the results of a tax subsidy scheme used to address the transboundary problem of global climate change a nonzero sum dynamic game with asymmetric players is used to evaluate the policy impact of the tax subsidy scheme on the respective player s value functions and strategies as determined by a nash equilibrium feedback solution the asymmetry of the players is reflected in their respective attitudes toward global climate change with one player benefiting from the change and the other losing

multidivisional firms internal competition and comparative advantage baye et al meet neary abstract we present a tractable general equilibrium model to capture the effects of divisionalization on trade in oligopolistic industries divisionalization reduces the incentives for diversification in production the extensive margins of trade expand as a result of divisionalization facilitating specialization toward the direction of comparative advantage with exports rising in the case of domestic divisionalization and imports rising in the case of foreign divisionalization this effect of internal competition on specialization is magnified when competition between divisions is staggered the factor market effects of divisionalization domestic and or foreign strengthen the expansionary effects on the extensive margins of trade

optimal designs of discrete response experiments in contingent valuation studies optimal designs for estimating model parameters and other characteristics such as mean and median willingness to pay are discussed when a logistic or a probit regression model is used for analyzing a contingent valuation study with discrete questions a numerical example related to a study of the value of preserving some virgin forests in sweden illustrates the efficiencies of different designs and how a sequential procedure can be applied copyright 1992 by mit press

corporate performance and managerial remuneration an empirical analysis abstract economic theories of efficient compensation predict a positive relationship between executive pay and corporate performance and yet efforts to document this relationship have been largely unsuccessful in this paper we argue that previous cross sectional studies have omitted important variables which seriously bias their results using data that focus on individual executives over time we find that executive compensation is strongly positively related to corporate performance as measured by shareholder return and growth in firm sales the results are robust to the stock market performance measure utilized

experimental evidence on the drivers of index based livestock insurance demand in southern ethiopia while index based microinsurance has attracted considerable attention uptake rates have been weak in many low income countries we explore the purchase patterns of index based livestock insurance in southern ethiopia focusing on the role of accurate product comprehension and price we find that randomly distributed learning kits improve subjects knowledge of the products however we do not find strong evidence that the improved knowledge per se causes greater insurance uptake we also find that reduced price due to randomly distributed discount coupons has an immediate positive impact on uptake without dampening subsequent period demand due to reference dependence associated with price anchoring effects

pesticide residue risk and food safety valuation a random utility approach a new approach is developed for integrating consumers risk perceptions with stated purchase behavior when consumption decisions must be made with incomplete information the application involves health risks from exposure to pesticide residues on fresh produce unlike traditional food demand analysis the present approach treats produce choices as discrete outcomes resulting in a random utility model empirical results from a pilot survey suggest a clear linkage between perceptions and behavior in response to new risk information consumers stated preferences for safer produce were primarily influenced by price differences and perceived risks not by the technical risk information provided alone however the linkage between behavior and valuation was less clear cut the risk price tradeoffs entailed by contingent discrete choices indicate high price premia for small risk reductions and little variation in price premium across alternative risk reductions

concept and unintended consequences of weather index insurance the case of mexico recently weather index insurance wii has received considerable attention as a tool to insure farmers against weather related risks particularly in developing countries donor organizations local governments insurance companies development economists as well as agricultural economists are discussing the costs and benefits of wii while the literature on wii has mainly focused on many cases in africa and asia in this article we analyze the wii program in mexico which is one of the largest wii programs worldwide in this context we discuss potentially important spill over effects on related markets which so far have not been considered in the academic literature first we argue that wii creates disincentives to invest in other non insured crops leading to potential overspecialization and monoculture secondly wii generates disincentives to invest in irrigation systems because farmers are insured only as long as production takes place on non irrigated land third in case of catastrophic events food prices can potentially inflate with indemnity payments at the expense of the uninsured poor we also suggest that in mexico the thresholds of the weather index be continuously re calibrated in order to adjust for the development of drought resistant seeds finally the index could relatively easily be extended to account for precipitation variances we argue that these factors and spillover effects should be accounted for in cost benefit analysis of wii this abstract was borrowed from another version of this item

on optimal domestic processing of exhaustible natural resource exports abstract this paper is concerned with the desirability of domestic processing of natural resource exports from a small open economy completely dependent upon these exports in the framework of a malleable capital model where the services of imported capital are needed to process the resource domestically the paper examines the optimal rates of extraction domestic processing and import of capital services in different economic scenarios defined in terms of processing technology cost and market structures presence or absence of taxes and subsidies historical growth in prices etc

measuring the cost of time in recreation demand analysis an application to sportfishing since the work of cesario and knetsch economists have recognized that the opportunity cost of time plays an important role in determining the demand for outdoor recreation the opportunities one has for spare time are more significant for consumption of time intensive outdoor recreation activities than for other commodities especially nondurables bishop and heberlein illustrate the overwhelming importance of time costs to final recreational values total consumer surplus is nearly four times as large when time costs are added at half the income rate as when time costs were set at zero p 21 despite the recognition economists have neither successfully integrated the costs of time with the methods of recreational demand analysis nor reached a consensus on how it should be measured brown charbonneau and hay state finally the apparently crucial importance of how opportunity cost of time is handled needs further work while we are convinced it is an appropriate concept exactly how it should be included and measured s remains to be determined p 24 several approaches have been taken to include it in the travel cost method one approach brown and nawas gum and martin suggests that time in transit be considered as a separate independent variable another approach bishop and heberlein brown charbonneau hay nicols bowes dwyer cesario and knetsch measures the cost of time and adds it to other costs several approaches have been suggested to measure time costs one approach is simply to choose an hourly wage e g 2 00 per hour or perhaps the minimum wage rate a more flexible but still ad hoc approach is to use some proportion of the individual s wage rate as the opportunity cost of time nichols bowes dwyer the proportion is usually taken from independent studies and used to value the travel time this approach is better than using a constant opportunity cost of time because it allows variation across individuals it suffers because the choice of the percentage of the wage rate is arbitrary independent of the sampled population cesario has discussed the consequences of ignoring time costs and the differences in values arising from alternative measurement approaches in this paper we argue that the opportunity cost of time is some proportion of the individual s market wage rate or income per hour and that this proportion can be determined from sample data this method permits the proportion to vary from one study to another rather than imposing either an arbitrary estimate or one from a sample different from the study s sample

economic behavior under uncertainty a joint analysis of risk preferences and technology a method is developed to estimate jointly risk preferences and technology under general conditions the approach is illustrated in an application to the analysis of u s corn soybean acreage decisions over time the results provide useful information on the nature of farmers risk preferences and on the influence of price risk and production risk on acreage allocation and farmers welfare copyright 1996 by mit press

sensitivity of contingent valuation to alternative payment schedules insensitivity to payment schedule wherein respondents do not adequately differentiate between a one time payment and a series of payments may be an important but often overlooked factor in the design interpretation and use of contingent valuation studies several contingent valuation experiments involving a familiar private good and a less familiar environmental commodity indicate that although respondents distinguished between lump sum and periodic payment schedules implicit discount rates were very high suggesting that sensitivity to payment schedule is an important subject for further study

weather index drought insurance an ex ante evaluation for millet growers in niger in the sudano sahelian region which includes south niger the inter annual variability of the rainy season is high and irrigation is limited as a consequence bad rainy seasons have a massive impact on crop yield and regularly result in food crises traditional insurance policies based on crop damage assessment are not available because of asymmetric information and high transaction costs compared to the value of production we assess the risk mitigation capacity of an alternative form of insurance which has been implemented at a large scale in india since 2003 insurance based on a weather index we compare the efficiency of various weather indices to increase the expected utility of a representative risk averse farmer we show the importance of using plot level yield data rather than village averages which bias results due to the presence of idiosyncratic shocks we also illustrate the need for out of sample estimations in order to avoid overfitting even with the appropriate index and assuming substantial risk aversion we find a limited gain of implementing insurance which roughly corresponds to or slightly exceeds the cost observed in india for implementing such insurance policies however when we separately treat the plots with and without fertilisers separately we see that the benefit of insurance is slightly higher in the former case this suggests that insurance policies may slightly increase the use of risk increasing inputs such as fertilisers and improved cultivars and hence improve average yields which remain very low in the region

design of sequential experiments for contingent valuation studies abstract sequential experimentation is recommended as an alternative to the usual one or two shot approach to contingent valuation surveys the sequential c optimal approach is introduced and developed and it is compared to the established parametric and non parametric sequential procedures it is shown to be an improvement in terms of statistical precision in a finite sample over the standard sequential procedures

divisionalization and strategic managerial incentives in oligopoly under uncertainty abstract this paper argues that divisionalization and incentive contracting are complementary rent shifting tools in the presence of demand uncertainty the role for divisionalization arises if managers know the state of demand prior to making output decisions and if incentive contracts are linear and non state contingent in this context incentive contracts achieve expected stackelberg outcomes but have no impact on the firm s responsiveness to demand shocks divisionalization on the other hand has the strategically beneficial effect of making the firm more responsive to demand shocks

substitution possibilities for unpriced natural resources restricted cost functions for the canadian metal mining industry a bstract the effects of resource depletion on economic growth depend critically on the elasticities of substitution between non renewable natural resources and reproducible inputs estimation of the elasticities of substitution for natural resources has been hindered by the absence of data on their prices which results from the prevalence of vertical integration in natural resource industries in this paper we use the theory of restricted cost functions to develop a general procedure for estimating substitution possibilities for unpriced inputs estimation of the model with data for the canadian metal mining industry indicates that the elasticities of substitution for the natural resource metallic ore are equal to unity

the merger paradox a tournament based solution according to the well known merger paradox in a cournot market game mergers are generally unprofitable unless most firms merge the present paper proposes an optimal merger mechanism with this mechanism mergers are never unprofitable more profitable than in other known mechanism and in many cases welfare increasing the proposed mechanism assumes that merged firms continue to operate as independent subsidiaries that are rewarded according to a simple and commonly observed relative performance measure

divisionalization and entry deterrence this paper assumes that incumbent firms can create new independent divisions more cheaply than potential entrants who must incur the additional overhead costs of new entry the main theoretical result is that such divisionalization ability leads perfectly informed incumbents to preempt all rational entry into their industries in contrast existing models of entry deterrence imply that informed incumbents even those with steadily decreasing average costs will often allow rational entry our result may explain why successful large scale entry by firms with no informational advantage is extremely rare the use of divisions to preempt entry may also explain why large firms in high profit oligopolies often divisionalize allowing their divisions to compete freely despite the negative pecuniary externality that each division imposes on others

safety nets and index based insurance historical assessment and semiparametric simulation for northern ghana abstract this article considers index based safety nets aimed at assuring participants a minimum income at the village level set by a prespecified poverty line the participating villages collectively manage a pooled budget offering an index based per capita indemnity to the villages financed from a uniform per hectare premium possibly supplemented by an external subsidy the scheme involves implicit cross subsidies in favor of the poorest villages otherwise it focuses on covariate risk leaving it to mutual arrangements to deal with intravillage idiosyncratic risk its design is obtained from a risk minimizing model for the collective of villages with constraints of two kinds the first is the budget that ensures that payments receive adequate finances the second concerns the set of admissible schedules requiring that payments are triggered by a flexible function of only a few variables for this we propose a semiparametric form from kernel learning noting its capacity to combine a priori on the i

the economics of sports facilities and their communities since the 1950s taxpayers have been the primary investors in stadia built for the use of privately owned professional sports teams team owners have argued that sports facilities boost local economic activity however economic reasoning and empirical evidence suggest the opposite public support for stadia is also driven by demand for community image and owners of sports teams supply a scarce input into image enhancement participation in the major league for which they have been able to extract monopoly rents from dispersed taxpayers we suggest reforms to dissipate the monopoly sports leagues exercise when negotiating with host communities for their teams

consumption risk technology adoption and poverty traps evidence from ethiopia much has been written on the determinants of input and technology adoption in agriculture with issues such as input availability knowledge and education risk preferences profitability and credit constraints receiving much attention this paper focuses on a factor that has been less well documented the differential ability of households to take on risky production technologies for fear of the welfare consequences if shocks result in poor harvests building on an explicit model this is explored in panel data for ethiopia historical rainfall distributions are used to identify the counterfactual consumption risk controlling for unobserved household and time varying village characteristics it emerges that not just ex ante credit constraints but also the possibly low consumption outcomes when harvests fail discourage the application of fertilizer the lack of insurance causes inefficiency in production choices
