option value empirical evidence from a case study of recreation and water quality a procedure for measuring option value and other preservation values of water quality is developed and applied to a case study area in the south platte river basin colorado benefits from water based recreation activities are the focus of the study the results provide an empirical test and confirmation of weisbrod s proposal that option value and other preservation values represent important social benefits and should be added to the aggregate consumer surplus of recreation activities to determine the total benefit of environmental amenities to society in the absence of such an estimate insufficient resources would be allocated by society to preservation of unique environments such as pristine mountain streams where mineral and energy development may irreversibly degrade water quality

valuing option existence and bequest demands for wilderness to assess the relative importance of current costs and future benefits of nuclear waste storage we develop a simple model of bequest value the basic model of nonparternalistic altruism is extended to account for the uncertain nature of the externality

globalisation and unequalisation what can be learned from value chain analysis although many have gained from the process of globalisation there remains a stubbornly large number of people living in absolute poverty and a rise in inequality within and between countries the issue is thus not whether to participate in the global economy but how to do so in a manner which provides for sustainable and equitable income growth this study shows how value chain analysis can be used to chart the growing disjuncture between global economic activity and global income distribution and to provide causal explanations for this outcome in so doing value chain analysis provides valuable insights into policy formulation and implementation

nonmarket values of major resources in the korean dmz areas a test of distance decay the demilitarised zone dmz and its adjoining areas serve not only as a geopolitical buffering zone between north and south korea but also as rare refuges for various animals and plants this paper investigates conservation values of major dmz resources and comparatively tests distance decay between contingent valuation and choice modelling the overall conservation value for the dmz resources per person as one off payments was 9 06 or 34 97 respectively from the cvm and cm datasets research findings deny distance decay regardless of elicitation methods when the distance variable is parameterised as part of utility functions conversely a segmentation valuation approach demonstrates conflicting conclusions on distance decay and the wtp anomaly between users and non users depending on elicitation methods the cm results demonstrate that protection of the dmz resources might be less important and attractive to local populations than to those in the distant regions a direct cross method transfer of any distance effect might not be granted

specification of the logit model the case of valuation of nonmarket goods abstract we address the proper specification of the logit model for estimation of nonmarket commodity demand economic theory is used to show the conditions which must be met by the logit functional form if it is to yield valid estimates of welfare change measures and demand relationships an empirical example is used to illustrate the argument recreational boating data were collected using the contingent valuation method cvm in texas in one instance the demand curve is positively sloped due to the specific functional form chosen the estimated demand curve for the theoretically preferred functional form has the expected negative slope

the effect of real exchange rate uncertainty on ldc manufactured exports abstract this paper uses pooled time series cross sectional data to conduct an empirical investigation of the relationship between real exchange rate uncertainty and the manufactured exports of developing countries export supply equations for four categories of manufactures are estimated using pooled data for ten countries over the period 1963 1985 evidence is found that some categories of ldc manufactured exports are negatively affected by real exchange rate uncertainty

revenue neutral tax policies under price uncertainty the firm s response to revenue neutral taxation is investigated under price uncertainty revenue neutral policies adjust simultaneously the marginal tax rate and the level of exemptions while keeping expected tax receipts constant nonincreasing absolute risk aversion is sufficient to sign the firm s response a reduction in the marginal rate causes the firm to contract output implications are established for the equilibrium level of treasury receipts

risky business multinationals uncertainty and asymmetric insurance a partial equilibrium model is used to examine the international production allocation of a two plant multinational firm that is confronted with uncertainty with respect to foreign sales the firm produces identical products in both plants using firm specific factors the internationally price discriminating multinational has monopoly power in both segmented markets the analysis focuses on how asymmetric insurance facilities between the firm s home and host country influence its international production allocation and level of intra firm trade

resolving conflicting ecological and economic interests in the korean dmz a valuation based approach abstract the demilitarized zone dmz between south and north korea has served as a sanctuary to diverse biological resources since the korean war ceased in 1953 during winter season flocks of cranes grus spp converge in the rice field along the dmz all other refuges for cranes that winter in south korea were destroyed due mainly to wilful industrial expansion in the past few decades the presence of cranes in this region is attributed to the residual rice grains left behind by harvesters this winter habitat is however very fragile for a number of reasons first the local formers regard the cranes as a potential threat in their livelihood rather than as an ecological member sharing the same ecosystem resources second exercising property rights the landholders have actively advocated an industrial development program third it is difficult to legally impose the notion of wildlife preservation even if there is a perception among the general public that the crane is worth preserving this study sought to formulate a policy measure to guide the local egalitarian farm economy to ecological economy in which farmers and cranes are the harmonized co users of the ecosystem resources valuation based approach is employed in our study to show that bio diversity is not in conflict with local economic well being but in fact essential to it

tax versus emissions trading scheme in the long run in this paper we compare the performance of emission taxes and tradable permits under free market entry when firms face idiosyncratic ex ante cost uncertainty we show that under auctioned permits insufficient entry occurs while under a linear emission tax scheme depending on parameters market entry can be either excessive or insufficient our long run analysis thus contrasts with spulber s 1985 equivalence result and also modifies weitzman s result in favor of an ets in that the superiority of a tax over an ets is not guaranteed even when the weitzman condition favors a tax we also show that an ets is superior to a tax scheme when the entry cost is low and the magnitude of uncertainty asymmetric information and the size of the output market are large

validation of empirical measures of welfare change a comparison of nonmarket techniques since the passing of the flood control act of 1936 the attention of many resource economists has been directed towards measuring the benefits and costs of alternative uses of natural resources increasingly it has been recognized that the value of some of these uses is not explicitly determined through market transactions this has led to the focus of much attention upon the development of nonmarket methods to estimate the value of these uses in the 1940s the groundwork for the travel cost method was established by hotelling prewitt 1949 following this in the 1960s davis initiated the basic foundation for bidding methods davis 1963 which were later to be subsumed under the heading of contingent valuation methods brookshire randall and stoll 1980 schulze d arge and brookshire 1981 thayer 1981 both of these methods will be further discussed below in addition to these two methods a third approach the unit day value method has been recognized as acceptable but not preferred for the valuation of recreational uses of water and related land resources dwyer kelley and bowes 1977 u s water resources council 1979 given the existence of alternative methods of estimating the value of resource uses several obvious questions arise one of the first of these is under what circumstances is each method most appropriate existing literature has focussed sufficiently on this question and pointed out limitations of each especially the travel cost method and unit day value methods brookshire ives and schulze 1976 dwyer kelly and bowes 1977 freeman 1979 mcconnell 1975 randall ives and eastman 1977 schulze d arge and brook

software industry entry strategies for developing countries a walking on two legs proposition abstract two themes run through the following analysis first countries without a relatively active and up to date software sector will find it increasingly difficult to catch up in terms of capital outlays labor skills and the growing importance of technology changes organization and management in software production they will not have for example software management experience to undertake increasingly large and complex software development projects a quality consciousness and the institutional and support infrastructure for marketing and forming product development alliances with dominant international firms in the sector second the learning curves for domestic and international market activities are quite different the domestic software market being an important base for skills experience and establishing a track record that may later be applied to exports two developing countries india and brazil have used different development strategies for their software industries and as could be expected with disparate results both the brazilian and the indian software industries are trying to walk on one leg the domestic leg in the case of brazil and the export leg in the case of india both countries have at least some potential for moving to a two legged model assessment of these two industries suggests that countries need to pay more attention to domestic opportunities since these have high returns in terms of gaining experience and innovation in software production and provide training that allows a broadening of software exports

valuation of ecotourism resources using a contingent valuation method the case of the korean dmz abstract the korean demilitarized zone dmz which has been untouched by human interference for the last half century has become a sanctuary for rare species of animals and plants conflicts concerning development between communities and environmentalists are arising estimates of the preservation value of the dmz are necessary for society to properly address these issues such estimates will help policy makers address issues of conservation management sustainable development and public financial support given this situation the objectives are two fold the primary objective of this study is to obtain estimates of the preservation value of the korean dmz and civilian control zone ccz a secondary objective is to examine the potential for hypothetic bias in respondents answers in a contingent valuation method framework findings suggest hypothetical bias is present in the survey including a real payment vehicle may reduce hypothetical bias in eliciting willingness to pay wtp best estimates are the mean wtp is us 16 74 per capita aggregate preservation value lies between us 264 and 602 million these findings indicate that conservation of the dmz and ccz is not only important for moral and ecological reasons but the dmz and ccz are of considerable economic value to south koreans any development unfriendly to the environment will degrade the quality of the ecosystem of the dmz as well as decrease its economic value

an experiment on spatial competition with endogenous pricing hotelling s 1929 principle of minimum differentiation and the alternative prediction that firms will maximally differentiate from their rivals in order to relax price competition have not been explicitly tested so far we report results from experimental spatial duopolies designed to address this issue the levels of product differentiation observed are systematically lower than predicted in equilibrium under risk neutrality and compatible with risk aversion the observed prices are consistent with collusion attempts our main findings are robust to variations in three experimental conditions automated vs human market sharing rule for ties individual vs collective decision making and even vs odd number of locations

industry equilibrium uncertainty and futures markets abstract this paper studies competitive long run industry equilibrium with uncertainty and futures trading we also provide a long run analysis of futures trading instead of the conventional short run analysis it is shown without using a general equilibrium model that given uncertain demand and risk aversion a bias backwardation or contango arises in long run industry equilibrium given risk neutrality such a bias however disappears we find that the occurrence of the bias depends not only on the existence of a risk premium but also on the length of the period considered each risk averse firm operates at a less efficient scale and moreover an expected spot price never accords with marginal cost when the expected spot price is less than marginal cost the risk averse firm can secure profit by selling futures contracts more than the amount of its output in the presence of production supply uncertainty a risk neutral firm operates with excess capacity under additive risk while the firm operates with proper capacity under multiplicative risk the key lies in whether its average cost curve is shifted by production risk

offshoring administrative and technical work new fields for understanding the global enterprise in this paper we introduce the journal of international business studies special issue on offshoring administrative and technical services ats in doing so we have attempted to locate the topic within the international business research tradition as well as suggest challenges and opportunities that the phenomenon offers to theoretical and empirical research in the field we examine the interplay of costs knowledge and innovation in the evolution of ats offshoring from modest beginnings to its current stature as an accepted business practice we suggest that understanding the continuing evolution of ats offshoring requires researchers to take into account not only the business imperative of cost saving but also a more complex set of underlying factors and potential outcomes we argue that the rapid growth of ats offshoring has brought about an accumulation of resources including financial flows knowledge infrastructure and human capital to create new platforms for knowledge creation and innovation low costs may characterize the initial conditions for offshoring but they also provide the basis for up market moves as firms increasingly pursue innovation based strategies we introduce the papers in the special issue as integral elements in our discussion contributing new ideas that stimulated our thinking and hopefully will do the same for others seeking to understand this emerging area of globalization and international managerial practice journal of international business studies 2009 40 887 900 doi 10 1057 jibs 2009 22

exchange rate uncertainty futures markets and the multinational firm abstract we consider a monopolistic risk averse multinational firm which sells and produces at home and abroad under exchange rate uncertainty first we show that the stochastic exchange rate implies higher production and lower sales in the foreign country then we analyze the impact of currency futures markets a separation result is obtained for a multinational firm i e production and the allocation of sales are independent of the distribution of the random exchange rate and of the firm s attitude towards risk we also examine the effect of currency futures on a multinational firm s foreign direct investments in the absence of futures markets we obtain some comparative statics results when risk aversion increases

the differential impact of uncertainty on investment in small and large businesses we study the impact of profit uncertainty on investment and whether or not this response is different in industries that are dominated by small firms versus those that are dominated by relatively larger firms our key findings are that the sign of the investment uncertainty relationship is negative and that the quantitative negative impact is substantially greater in industries dominated by small firms these results are robust to accounting for potential endogeneity of the uncertainty measure alternate procedures for measuring uncertainty and alternate ways of segmenting industries into small and large firm groups

asymmetnc taxation and the theory of the competitive firm under uncertainty this paper examines the implications of the asymmetries in the tax treatment of corporate profits and losses for the theory of the competitive firm under uncertainty it is shown that the tax asymmetry introduces a curvature into the firm s target function which affects its behaviour in the short run in long run industry equilibrium however most of the effects disappear at the firm level but still remain at the industry level

environmental attitudes as wtp predictors a case study involving endangered species this paper investigates environmental attitudes as significant motives for the behavioral intention of willingness to pay wtp involving endangered species in a choice modeling context and examines the underlying causal mechanism pro environmental attitudes are measured using the new ecological paradigm nep scale although the empirical evidence of this paper supports a significant attitude wtp association the causal mechanism is different from previous theorizing when observed at the parameter level using random parameter logit models the significant causal linkages are evident with both the target good and the payment variable the findings of this paper not only support direct and indirect impacts of general attitudes on wtp but also provide novel findings about the causal mechanism for a significant attitude wtp relationship at the parameter level in a non western case study the impact of past visiting experience was also significant on the relationship undermining the impact of attitudes on wtp

noise a firm made trade barrier abstract a dominant domestic firm confronted by a fringe of risk averse importers achieves higher profits by adopting a volatile price policy than by setting quantity according to the standard marginal condition the fluctuating domestic price is equivalent to a tariff on imports for all intents and purposes the local firm raises its rivals costs

the comparative statics of a competitive industry facing demand uncertainty abstract the comparative statics of a competitive industry under uncertainty with free entry is clarified and extended using the general structure of random demand due to leland 1972 while strong results are obtained for the industry few unambiguous results can be derived for the firm

estimating the use and preservation values of national parks tourism resources using a contingent valuation method abstract the korean national parks authority has questioned whether natural resources have enough economic value to justify an increase in admission fee in the case of inadequate assistance from the government alternatively they also question whether the national parks have sufficient value to contribute to citizens welfare in order to receive continuing support from the government hence the purpose of this research is to estimate the use and preservation values of natural and or cultural resources in five distinctive national parks using a dichotomous choice contingent valuation method the empirical results show that natural and or cultural resources of the sample national parks possessed considerable use and preservation values outweighing current admission fees and maintenance costs per visitor thus these values provide enough justification for the national park authority to increase admission fees to maintain the quality of natural environment and avoid degrading natural resources in the event of no assistance by the government the findings may provide guidance to national park managers and practitioners who establish pricing policies the results also show that values of natural and or cultural resources were different across five distinctive national parks indicating the possibility of employing differential admission fees according to park characteristics

how do landowners price their lands during land expropriation and the motives behind it an explanation from a wta wtp experiment in central beijing compensation paid to property owners for land expropriation is always a controversial topic partly due to the difficulty in revealing households true valuation of their housing this paper estimates and discusses the widely observed willingness to accept willingness to pay wta wtp gap for surveyed residents of their own houses during land expropriation by testing several hypotheses interpreting the wta wtp disparity from previous studies the paper tries to establish the incentive for households decision making the paper employs a contingent valuation method with data from 315 household interviews in central beijing china the paper reports an average wta wtp ratio of 3 74 and reaches the conclusion that in our case the high compensation required by property owners largely derives from opportunistic pricing behaviour rather than sentimental attachment to the dwellings that is unobservable in the market price and that the wta of the residents is intentionally overpriced

the effects of product price uncertainty on the owner managed firm theory and evidence in this paper we extend the theory of the owner managed firm to incorporate product price uncertainty and we present an empirical test of the model s predictions under product price uncertainty the trade off between leisure and profit faced by an owner manager is combined with the trade off between surety and risk bearing faced by an entrepreneur the firm s owner bears the uninsurable and undiversifiable risk about profit caused by product price uncertainty and as manager supplies the firm a unique labor factor the model predicts that the substitution effect of an increase in risk on the quantity supplied by the firm is negative the income effect of risk reinforces the substitution effect if the entrepreneur s labor supply has a positive wage elasticity but runs counter to and could dominate the substitution effect if the wage elasticity of labor supply for the entrepreneur is sufficiently negative unlike previous research on price uncertainty and the firm this paper presents an empirical test of the model s predictions using data on physicians in solo practice our empirical analysis indicates that although wage elasticities of labor supply for the physician entrepreneurs are negative greater risk leads to a reduction in output these results suggest that the substitution effect is dominant in determining the response to product price uncertainty for the owner managed firms in our sample frank knight 12 gave prominence to the risk bearing role of the entrepreneur who as residual claimant bears the risk associated with a firm s revenue tibor scitovsky 21 later emphasized a different aspect of entrepreneurial activity the trade off confronted by an ownermanager between consumption of leisure and pursuit of profit both models of the entrepreneur are relevant to predicting the behavior of an owner managed firm operating in a risky environment the entrepreneur in such a firm must choose between consuming leisure and supplying labor which provides an uncertain return the random residual of revenue net of payments to other factors

revenue neutral tax policies under price uncertainty reply in their comment on my 1990 article yeh suwanakul and mai extend my analysis which focused attention exclusively on firm output to allow for simultaneous endogeneity of price aggregate output and numbers of firms they show that with downward sloping demand industry output adjusts positively to revenue neutral changes in the marginal rate of taxation this result is significant for two reasons first we are more often interested in predictions about aggregate phenomena than we are in predictions about individual firms indeed firm level predictions are frequently irrefutable since firm data are often unavailable second the authors derive their result under a set of conditions that appear to be more general than those invoked in my 1990 article in particular they circumvent the need to invoke specific assumptions about the nature of firms aversions toward risk i consider this a useful extension and i appreciate the careful scrutiny of my paper

the aggregate effects of risk in the agricultural sector the theory of the firm facing a random output price is extended to include industry equilibrium conditions in a way particularly important for agriculture land prices adjust to maintain industry equilibrium the comparative statics and the effects of policy for the firm are significantly altered the main finding is that risk and other parameter changes are capitalized into the price of land and yield wealth or income effects rather than substitution effects this often simplifies the analysis

competitive industry equilibrium under uncertainty and free entry this paper investigates the properties of industry equilibrium under price uncertainty given free entry and exit for any form of risk averse behavior it is shown that an increase in demand uncertainty as measured by a mean preserving spread increases mean output price and reduces output of firms in long run equilibrium

risk aversion and technology mix in an electricity market this article analyzes the eff ect of risk and risk aversion on the long term equilibrium technology mix in an electricity market it develops a model where fi rms can invest in baseload plants with a fi xed variable cost and peak plants with a random variable cost and demand for electricity varies over time but is perfectly predictable at equilibrium the electricity price is partly determined by the random variable cost and the returns from the two kinds of plants are negatively correlated when the variable cost of the peak technology is high the return of peak plants is low but the return to baseload plants is high risk averse fi rms reduce the capacity of the riskiest technology and develop the capacity of the other compared to risk neutral fi rms in the particular case where a risk neutral fi rm invests heavily in baseload technology and only sparely in peak capacity a risk averse fi rm would invest less in baseload increase peak capacity and increase total installed capacity

input choices and uncertain demand the theory of the firm under demand uncertainty has to date assumed that the firm s input decisions are unaffected by the stochastic nature of demand this assumption is not usually made explicitly but it is implied by the assumption that the firm s cost function presumably derived by finding the minimum cost combination of inputs for any given level of output is unaffected by the uncertainty however if firms must choose some of their inputs before the uncertainty regarding demand is resolved then different input decisions may involve different levels of risk since firms decisions regarding price and output are affected by demand uncertainty and non linear risk preferences as previous authors have shown it seems reasonable to suspect that their input decisions will also be affected but if input decisions are affected then firms cost functions are not invariant to uncertainty and the results of previous studies must be reexamined three different types of firms are considered in this paper the competitive firm the quantity setting imperfect competitor and the price setting imperfect competitor input decisions of the competitive firm and the quantity setting imperfect competitor are shown to be unaffected by demand uncertainty and hence the assumption of an unchanging cost function is appropriate in these cases for the price setting imperfect competitor however input decisions are influenced by demand uncertainty and an unchanging cost function is therefore not appropriate this case is considered in some detail and conditions under which results can differ from those previously reported in the literature are examined

uneven and combined development understanding india s software exports abstract the evolution of the indian software sector is explained by the larger context of uneven and combined development the imperatives of a market driven global order suggest an open ended process of development making some economic and technological convergence realizable but also generating contradictions at various levels this paper focuses on differential innovative capability the uneven diffusion of technical education in india and the increasing economic integration of the software industry as sources of uneven development the combined nature of the development process is reflected in the coexistence of the successful software sector with several lagging sectors with all of them being functionally integrated as part of indian social formation to cope with the contradictions of such change a balanced development will be critical to make development more inclusive deep structural problems that plague those outside the orbit of the successful software industry must be resolved

revenue neutral tax policies under price uncertainty comment in an interesting paper in this journal holloway investigated the firm s response to revenue neutral taxation under price uncertainty in his analysis revenue neutral policies adjust simultaneously the marginal tax rate and the level of exemptions while keeping expected tax receipts constant using an assumption of nonincreasing absolute risk aversion he concluded that a reduction in the marginal rate would cause the firm to contract output holloway used the 1986 tax reform act as an example of a revenue neutral policy as a matter of fact the act was intended to be revenue neutral while low

a note on free entry under uncertainty the role of asymmetric information in a model of competing managerial firms i show that the equilibrium number of firms decreases with uncertainty if entry is relatively more costly than monitoring the result adds to the earlier contributions and is consistent with the available evidence

the next wave of globalization relocating service provision to india summary services offshoring to india has grown dramatically in the last 10 years it is linked to the earlier expansion of indian software services exports but has its own dynamic and workforce although domestic firms were early entrants mncs are central actors already some work done in india resembles that done in developed countries to explain the dynamism and complexity of offshoring a taxonomy of market participants is presented offshoring by small entrepreneurial us firms is highlighted as an emerging phenomenon the conclusion argues that market entry by other developing countries is possible

broken symmetry symmetry and price uncertainty or short and long run comparative statics of the competitive firm abstract the notion of broken or hidden symmetry is applied to a long run characterization of a competitive firm operating under price uncertainty the main result of the paper is the restoration of a slutsky type symmetry of the input demand functions within an expected utility framework which does not involve any assumption about risk aversion a second conclusion is that economic relations expressed in terms of relative quantities are essential in the long run comparative statics under price uncertainty

production decisions under joint price and production uncertainty abstract while production decisions in the presence of price uncertainty have been extensively studied this is not so for the case in which the level of production is itself uncertain in this paper we provide a decision analysis under multiplicative production uncertainty both with and without price uncertainty we depict equilibrium and obtain comparative statics results with the aid of a diagram based on the difference between expected price and marginal cost comparative statics results are obtained for the model with production uncertainty alone and also for simultaneous price and production uncertainty including two special cases we first derive results based on the arrow pratt coefficients of risk aversion and then supplement these with the ross measure of relative risk aversion since this proves useful in the presence of multiple sources of uncertainty we find that increases in risk both price and production or input prices reduce expected output however expected output supply is an increasing function of expected price only for low levels of risk aversion and in general the relationship is ambiguous

an examination on the cost efficiency of the banking industry under multiple output prices uncertainty this article formulates a behavioural model of profit maximization which explicitly incorporates both multiple output prices risk and safety first practice this theoretical model is specifically suitable for investigating financial institutions whose output prices frequently encounter a variety of risks such as loan defaults arrears the sample banks are empirically found to be highly risk averse furthermore risk preferences exert little effect on the technical efficiency estimates whereas the same estimates obtained by the standard fixed effect model under certainty tend to be overestimated evidence is found that a specialized bank offering a single product with a larger scale of production will be preferable in an uncertain atmosphere

supply response under proportional profits taxation a striking result in the theory of the competitive firm under certainty is the proposition that a proportional profits tax with full offsets for losses will have no impact on optimal output this result does not apply under uncertainty it is shown that under constant or increasing returns to scale a proportional profits tax will yield an unambiguous expansion in output the same result is shown to hold for the more general rank dependent expected utility rdeu model

measuring birdwatchers preferences a case for using online networks and mixed mode surveys abstract this paper reports findings derived from a study of birdwatchers in the azores the subject was birdwatchers preferences for given management actions designed to improve the attractiveness of bird watching sites in the absence of official statistics on this market segment use was made of a mixed mode survey incorporating both on site and off site surveys and the use of on line social networks and communications tools the variable willingness to stay more time at the site was used as a welfare measure it has the advantage that it can be used to demonstrate the significant returns of eco tourism to local communities two findings emerge first tourists practicing wildlife viewing and nature based activities are less worried about infrastructures and care more about biodiversity and habitat quality and second the research technique appears to be successful when surveying seasonal recreation communities that are small and socially cohesive

price uncertainty and the price discriminating firm in international trade the firm operating in an uncertain environment was initially analyzed in detail by sandmo 1971 and by leland 1972 since these early papers many extensions to the analysis have been explored by such writers as batra and ullah 1974 mayer 1975 hartman 1976 holthausen 1976 stewart 1978 paroush and kahana 1979 anid katz and paroush 1979 this paper investigates the optimal policy of a pr ice discriminating firm which operates under pr ice uncertainty in one of two markets the main motivation for the analysis comes from the problems of a firm which sells its output both domestically and abroad such a firm often has nearly full information about the domestic market b ut faces uncertainty in foreign markets in particular the firm which has its utility defined over profits denominated in terms of domestic currency will regard the profits on its foreign sales as uncertain given excha nge rate variability even if it has full information about all other conditions in the foreign market hence the paper may be regarded both as an extension to the above mentioned analyses of the firm under uncertainty and as an attempt to throw light on the activities of firms involved in international trade the treatment being essentially of a mricroeconomic nature is clearly different from that of such writers as batra 1 975 and helpman and razin 1979 which are essentially macroeconomic treatments

on output price uncertainty and the comparative statics of industry equilibrium the analysis of firm response to output price variability has until recently been incomplete due to a failure to consider explicitly the effect of firm response on the attainment of competitive equilibrium at the industry level a recent paper by appelbaum and katz 1 has addressed the issue of industry equilibrium under output price uncertainty they show how the optimal number of firms might change through the process of exit and entry and they characterize the collective influence of firms decisions on expected market price however their analysis focuses on firms with a single stage production process which allows no production flexibility in the form of adjustment of output levels after output price is revealed an earlier paper by hartman 3 has shown that at the firm level the optimal response to output price uncertainty will depend on whether production flexibility exists specifically if firms employ a two stage production process which is characterized by the presence of a quasi fixed factor then firm level output may increase or decrease in response to changes in output price variability even if firms are risk neutral the assumption that production flexibility exists changes those results initially developed by sandmo 7 and applied more recently by appelbaum and katz 1 which are based on a single stage production process this paper provides an extension of the appelbaum and katz analysis to admit production flexibility equivalently it extends the analysis of hartman to consider explicitly the effect of firm response on the attainment of competitive equilibrium at the industry level appelbaum and katz show that for an industry of identical risk averse firms with a singlestage production technology the effect of a mean preserving increase in price uncertainty is to decrease industry output and to raise market price a more recent comment by ishii 5 shows that output per firm will also fall yet none of these authors shows unambiguously whether the number of firms increases or decreases although not explicitly stated the analysis in appelbaum and katz suggests there would be no firm or industry response to a mean preserving change in price spread if firms were risk neutral expected profit maximizers the model employed in this paper is analogous to that of appelbaum and katz with two principal exceptions i here an industry is composed of firms all of which are either risk neutral

resource management under production and output price uncertainty implications for environmental policy various environmental policies have been proposed to control agricultural runoff of nutrients and pesticides the impacts of these policies on input use are complicated because of the various sources of uncertainty farmers face and the precise nature of farmers risk attitude a risk averse farmer s response to changed profit input and output taxes under output price and production uncertainty is examined the impact of these policies on input use depends on the form of production uncertainty risk input relationships risk attitudes and degrees of output price and production uncertainty these results have implications for the design and implementation of environmental and other production related policies copyright 2002 oxford university press

are commercial fishers risk lovers fishers are risk averse according to most empirical studies while expected utility theory predicts risk neutrality even for sizable stakes we test this prediction using data from a stated choice experiment with swedish commercial fishers our results show that only 48 of the fishers can be broadly characterized as risk neutral while 26 are modestly risk averse and 26 are strongly riskaverse fishers are more risk neutral the higher the fraction of their household s income comes from fishing sensitivity testing implies that modest stake decisions like a few days of fishing are not influenced by wealth level

theory of the firm under the threat of input supply interruption economists have been intrigued by the behavior of firms under different types of risk and uncertainty relatively recently there has been a particular interest in the theory of production under input uncertainty perhaps as a reflection of the energy supply disruptions experienced in the 1970s nevertheless this literature concentrates on the firm s production decisions when the uncertainty stems from stochastic input deliveries or from the production process itself this paper extends the stochastic input analysis to the monopolistic firm operating under the threat of input supply interruption turnovsky 8 presents some results pertaining to production decisions under input supply uncertainty he examines the risk neutral competitive firm s response to a randomly delivered input allowing the firm to reject excess order deliveries martin 6 examines the competitive firm s optimal short run response to stochastic deliveries where the entire input deliveries cannot exceed orders in these frameworks random deliveries can stem from internal sources such as machine failures or external sources such as unanticipated input market shocks and transportation breakdowns both studies demonstrate that the uncertainty induces a stochastic input ordering bias by the firm while turnovsky 8 finds that the existence of uncertainty in one input supply will not alter the optimal order of the nonstochastic input this is the so called input independence result martin 6 finds that the effect of the uncertainty on the nonstochastic input orders will depend upon the inputs relationship in production in this paper as in turnovsky s and martin s papers the supply of one perishable input is stochastic unlike the existing models however the ex post input supply under the threat of interruption is dichotomous either interruption occurs in which case none of the input is delivered to the firm or interruption does not occur in which case the entire input order is delivered to the firm also the existing work by turnovsky 8 and martin 6 concentrates on the competitive firm whereas this paper focuses on the monopolistic firm s behavior under factor supply uncertainty 2

on the theory of the competitive firm under uncertainty when initial wealth is random since sandmo s seminal paper on the theory of the competitive firm under output price uncertainty there has been considerable research on this topic 2 5 6 10 11 14 in all these studies it is assumed that in the absence of complete contingent markets output price risk is the only source of uncertainty for the firm however this may not be a realistic assumption in particular as argued by kihlstrom et al 7 it appears reasonable to consider the case where some of the initial wealth of the firm is held in risky assets in that case initial wealth is uncertain and should be modelled as a random variable the objective of this paper is to investigate the introduction of random initial wealth in sandmo s theory of the firm under price uncertainty in sandmo s model a number of important comparative static results e g the conditions under which the supply function is upward sloping 14 69 or under which increased price uncertainty reduces supply 5 depends critically on the sign of a particular expression stated in lemma 2 in ishii 5 while sandmo 14 69 shows this expression is non negative under arrow pratt decreasing absolute risk aversion it can be verified that his proof no longer holds when initial wealth is random therefore the comparative static analysis conducted by sandmo 14 batra and ullah 2 and ishii 5 is no longer valid and gives ambiguous results under initial wealth uncertainty the reason is that the arrow pratt measures of risk aversion 1 12 are too weak for making comparisons in situations where there is more than one source of uncertainty 13 then what can be deduced from the theory of the competitive firm in the realistic case where both initial wealth and output price are uncertain we will show here that meaningful results on the behavior of the competitiv firm under uncertainty can be obtained provided that the arrow pratt measures of risk aversion 1 12 are replaced by the ross measures of risk aversion 13 in particular a comparative static analysis of the production decisions using ross characterization of risk behavior is presented a number of new results are derived on the properties of risk responsive supply and input demand functions under both price and initial wealth uncertainty

limits to substitution and irreversibility in production and consumption a neoclassical interpretation of ecological economics abstract there are many methodological approaches within ecological economics one of the principal modes of analysis is a modified version of the standard neoclassical model this paper examines the parallels which emerge between the ideas of some ecological economists concerning production and the ideas of others concerning consumption when these ideas are interpreted in the neoclassical paradigm it is well known that ecological economics is characterized by arguments concerning limits to substitution between inputs energy natural capital etc vs manufactured capital labor etc in production and the implications these have for sustainability however various authors have also expressed concerns regarding limits to substitution in consumption either between environmental assets and other goods or between basic needs commodities and other goods though the specific reasons for non substitution are different in the production and consumption cases the underlying theme is that individual commodities and other inputs have unique physical or other properties which make them poor substitutes ideas about irreversibility in production and economic development are also prominent in ecological economics likewise many authors have argued for similar irreversibilities in consumption behavior in analogy to the term technological change i coin the term preferential change to describe these phenomena the linking themes in this case are that the economy environment system is evolutionary in character and that external effects intended and unintended consequences of actions or processes imposed on other parties or resources are all pervasive

analysis of food stamp participation using qualitative choice models food stamp program participation at the household level was analyzed using a nationwide sample of households as well as refined measures of residential location source of income and household age distribution additionally an empirical comparison of probit analysis vis a vis logit analysis was provided the criteria for the comparison consisted of the use of estimated parameter values signs magnitudes and test statistics goodness of fit to sample data predictive ability to independent data samples and non nested testing procedures on the basis of this application the two alternatives appeared to perform equally well

collusion under risk aversion and fixed costs we analyze collusion under demand uncertainty by risk averse cartels that care about the utility derived from profits with sufficient risk aversion and non trivial fixed operating costs it becomes difficult for cartels to collusively restrict output both when demand is low and marginal dollars are highly valued and when demand is high and potential defection profits are high output relative to monopoly levels becomes a u shaped function of demand greater risk aversion or higher fixed operating costs make collusion more difficult to support in recessions but easier to support in booms

discriminating monopoly forward markets and international trade recent empirical studies see e g kravis and lipsev 1977 1978 isard 1977 aspe and giavazi 1982 demonstrate that there are notable divergencies between domestic and export prices this empirical evidence suggests that the law of one price is systematically violated kravis and lipsey 1977 p 155 argue that many firms involved in international trade particularly manufacturers are in the position of a discriminating monopolist faced with separate markets each characterized by a different demand elasticity a model which explicitly allows for price discrimination has been used by several authors see for example aspe and giavazi 1982 ethier 1982 katz paroush and kahana 1982 and tarr 1979 katz paroush and kahana 1982 hereafter kpk used a model of a price discriminating firm which operates under price uncertainty to investigate its optimal level of output and sales in the two markets the main assumption made in kpk 1982 is that the firm determines its level of output and the allocation of sales between the two markets before the resolution of uncertainty furthermore no forward markets were available to this firm in this paper we analyze a price discriminating firm which sells its produce both in the domestic and on world markets under either exchange rate uncertainty or foreign price uncertainty this firm is a monopoly in the domestic market but a price taker on the world market our model differs substantially from the kpk model and in some cases conforms better with reality due to the following two assumptions first the firm determines its level of output before the resolution of uncertainty but decides about the optimal allocation of sales only after it observes the foreign price denominated in domestic currency secondly forward markets to share the exchange rate risk or the uncertain foreign commodity price are available and their impact on the firm s policy is analyzed hence this work integrates two strands of literature it combines studies on price discriminating firms some were mentioned above and studies on firm behavior when forward markets are available danthine 1978 holthausen 1979 katz and paroush 1979 feder just and schmitz 1980 in this paper we are mainly concerned with a firm which always exports this includes large

production effects of price and cost based anti dumping laws under flexible exchange rates this paper investigates the production response of an exporting firm when faced with the threat of an anti dumping ad action the firm s production decision is sensitive to market conditions at home and abroad as well as to the definition of dumping we examine the incentives facing the exporting firm under price based marginal cost based and average total cost based anti dumping laws depending on the nature of the anti dumping rules and market conditions a firm s production may rise fall or remain unchanged in response to ad legislation les effets de production des lois anti dumping fondees sur les prix et sur les couts dans un
