economic determinants of free trade agreements abstract the purpose of this study is to provide the first systematic empirical analysis of the economic determinants of the formation of free trade agreements ftas and of the likelihood of ftas between pairs of countries using a qualitative choice model we develop this econometric model based upon a general equilibrium model of world trade with two factors of production two monopolistically competitive product markets and explicit intercontinental and intracontinental transportation costs among multiple countries on multiple continents the empirical model correctly predicts based solely upon economic characteristics 85 of the 286 ftas existing in 1996 among 1431 pairs of countries and 97 of the remaining 1145 pairs with no ftas

fiscal paradise foreign tax havens and american business the tax haven affiliates of american corporations account for more than 20 percent of u s foreign direct investment and nearly a third of the foreign profits of u s firms american companies report extraordinarily high profit rates on their tax haven investments in 1982 this behavior implies that the revenue maximizing tax rate for a typical haven is around 5 8 percent american and foreign investment in tax havens has an uncertain effect on u s tax revenue but since low tax rates encourage american companies to shift profits out of high tax foreign countries it is possible that low foreign tax rates ultimately enhance u s tax collections

environmental influences on mne subsidiary roles economic integration and the nordic countries we seek to examine the importance of environmental factors in determining mne subsidiary roles in particular we examine the environmental factors associated with deep integration schemes such as the eu such schemes require a convergence of economic structure due to the establishment of common regional institutions regulations and policies specifically we distinguish between the scope of activities performed by subsidiaries and the level of competence of those subsidiaries the empirical analysis is based on a large scale survey of foreign owned units in denmark finland and norway these nordic countries differ with regard to their eu membership status norway being the outsider while the others are members but are very similar to each other in most other respects our data show that subsidiaries in norway report significantly lower scores for both scope of activities and levels of competence the effects remain strong even when we are controlling for other potentially influential factors the findings indicate that being on the outside of the eu may indeed carry the price of becoming less attractive to mne activity

fdi as an outcome of the market for corporate control theory and evidence abstract much foreign direct investment fdi takes the form of mergers and acquisitions m a it is commonplace in finance to view acquisitions as manifestations of the market for corporate control following on that insight we propose a model of fdi in which headquarters bid to control overseas assets we derive an equation for bilateral fdi stocks that resembles the recently developed fixed effects approach to modelling bilateral trade flows we estimate the model and use its parameters to construct benchmarks for evaluating multilateral inward and outward fdi

u s multinationals and preferential market access this paper examines the relationship between oshoring activity by u s multinational rms and the structure of u s trade preferences we combine rm level panel data on u s foreign aliate activity from the u s bureau of economic analysis bea with detailed measures of u s trade preferences from the u s international trade commission usitc to create a three way panel that spans 80 industries 184 countries and ten years 1997 2006 consistent with existing theory we nd that o shoring and preferential market access are positively and consistently correlated both in the pooled sample and within countries industries and years using both instru mental variables and simultaneous equations approaches to address the endogeneity of export oriented foreign investment we nd that a 10 increase in u s foreign aliate exports to the u s from a particular industry and country is associated with a 4 per centage point increase in the rate of preferential duty free access restricting attention to the generalized system of preferences gsp among potentially eligible develop ing countries we nd that the inuence of multinational aliate sales on preferential market access more than triples

intra industry foreign direct investment we use a new firm level data set that establishes the location ownership and activity of 650 000 multinational subsidiaries close to a comprehensive picture of global multinational activity a number of patterns emerge from the data most foreign direct investment fdi occurs between rich countries the share of vertical fdi subsidiaries which provide inputs to their parent firms is larger than commonly thought even within developed countries more than half of all vertical subsidiaries are only observable at the four digit level because the inputs they are supplying are so proximate to their parent firms final good that they appear identical at the two digit level we call these proximate subsidiaries intra industry vertical fdi and find that their location and activity are significantly different to the inter industry vertical fdi visible at the two digit level these subsidiaries are not readily explained by the comparative advantage considerations in traditional models where firms locate their low skill production stages abroad in low skill countries to take advantage of factor cost differences we find that overwhelmingly multinationals tend to own the stages of production proximate to their final production giving rise to a class of high skill intra industry vertical fdi

power politics and international trade r recent literature attributes the relative scarcity of open international markets to the prisoner s dilemma structure of state preferences with respect to trade we argue that the prisoner s dilemma representation does not reflect the most critical aspect of free trade agreements in an anarchic international system namely their security externalities we consider these external effects explicitly doing so leads us to two conclusions 1 free trade is more likely within rather than across political military alliances and 2 alliances are more likely to evolve into free trade coalitions if they are embedded in bipolar systems than in multipolar systems using data drawn from an 80 year period beginning in 1905 we test these hypotheses the results of the analysis make it clear that alliances do have a direct statistically significant and large impact on bilateral trade flows and that this relationship is stronger in bipolar rather than in multipolar systems in the early 1970s students of international relations began what would become a long and heated debate about the political correlates of open international markets recently however an important element of consensus has begun to emerge most contributors to this debate now seem to agree that the prisoner s dilemma structure of state preferences with respect to trade explains the relative dearth of open international markets here we argue that what has become the standard prisoner s dilemma representation neglects the most critical aspect of free trade agreements in the anarchic international system namely their security externalities we consider these external effects explicitly in order to do so we construct and analyze a simple game theoretic model the results of this analysis demonstrate that tariff games between allies differ systematically from those played between actual or potential adversaries these differences imply that free trade is more likely within rather than across political military alliances however our analysis also suggests that the evolutionary prospects of alliances vary those that are the products of bipolar systems are more likely to evolve into free trade coalitions than are their multipolar counterparts less credible exit threats and clearer responsibilities for alliance stability explain the advantage of a bipolar system we test this argument using data drawn from an 80 year period beginning in 1905 the empirical analysis supports our argument it demonstrates that alliances have a direct statistically significant and large effect upon bilateral trade moreover it shows that on average alliances have a much stronger effect on trade in a bipolar than in a multipolar world 2

how trade and investment agreements affect bilateral foreign direct investment results from a structural gravity model the paper develops a new stand alone structural gravity model for explaining bilateral fdi patterns we employ the model to analyse the impact of preferential trade agreements ptas bilateral investment treaties bits and other policies on bilateral foreign direct investment fdi we use the unctad global database on bilateral fdi stocks and flows to control for the heterogeneous nature of ptas we employ two different indicators of pta depth we find that on average signing a pta increases bilateral fdi stocks by around 30 nevertheless we also find that deeper or comprehensive ptas e g including provisions on investment public procurement and intellectual property rights provisions do not have a significantly different impact than signing regular ptas belonging to the eu single market on the other hand has a strong impact and increases bilateral fdi by around 135 and signing a bit has an effect that is comparable to signing a pta

intra national versus international trade in the european union why do national borders matter the first objective of this paper is to estimate border effects among european union countries in this context the specification of the gravity equation together with the choice of the distance measure are shown to be crucial for assessing the size of the border effect the second objective is to evaluate the determinants of the cross commodity variation in national border effects contrary to previous findings reported in the literature we show that trade barriers do provide an explanation in particular technical barriers to trade together with product specific information costs increase border effects whereas non tariff barriers are not significant our results further suggest that these barriers are not the only cause since the spatial clustering of firms is also found to matter

multilateral trade liberalisation foreign direct investment and the volume of world trade a cournot duopoly model is used to explain the paradox that multilateral trade liberalisation has resulted in increases in both the volume of world trade and the amount of foreign direct investment fdi

preferential trade areas multinational enterprises and welfare the effects of preferential trade areas ptas on the investments by multinational enterprises and their implications for the welfare of members and non members are studied in a model with two types of firms national firms and multinational firms in the presence of multinational activity ptas can create new investment as well as divert investment from non members to members both affect the welfare of members positively more interestingly if the investment creation effect of a pta is sufficiently strong then the pta could be welfare enhancing for non members as well jel classification f2 l1 aires preferentielles de commerce entreprises plurinationales et bien etre on etudie les effets des aires preferentielles de commerce apc sur les investissements par les entreprises plurinationales et leurs implications pour le bien etre des pays membres et non membres a l aide d un modele ou l on retrouve deux genres d entreprises les entreprises nationales et plurinationales quand des operations plurinationales existent les apc peuvent creer de nouveaux investissements mais aussi deplacer certains investissements des pays non membres vers les pays membres ces deux effets affectent le niveau de bien etre des pays membres positivement il est interessant de noter que si l effet de creation d investissements d une apc est suffisamment puissant l apc peut entrainer une augmentation du niveau de bien etre des pays non membres

the complex integration strategies of multinationals and cross country dependencies in the structure of foreign direct investment abstract the behavior of many multinational enterprises is not well described by existing models of foreign direct investment fdi firms often follow strategies that involve vertical integration in some countries and horizontal integration in others a strategy known as complex integration this paper presents a three country model that is used to analyze why firms might follow a strategy of complex integration my analysis reveals that complex integration strategies create complementarities between potential host countries that have important implications for the structure of fdi the analysis also shows that falling transport cost between countries may increase the importance of complex integration strategies

interdependence in multinational production networks the majority of multinational firms today operate a multilateral production network most existing empirical analyses have however focused on firms choice between producing at home and investing overseas and assumed that a firm s decision to invest in a foreign country is independent of its locations in third countries this paper examines the effect of existing production network on multinationals entry decision using detailed french multinational subsidiary level data the paper finds strong evidence of horizontal and vertical interdependence across multinationals foreign production locations there is however little evidence of horizontal interdependence between home country production and foreign investment when the third country effects are taken into account constituting a sharp contrast to the conventional emphasis this result is robust to the various specifications and sensitivity analyses undertaken in the paper and highlights the importance of investigating the causes and effects of foreign direct investment in the context of multinational production network

u s canada trade liberalization and mnc production location using confidential firm level panel data from the bureau of economic analysis we examine how the bilateral trade flows of u s multinational corporations mncs and their canadian affiliates responded to u s canadian tariff reductions from 1983 to 1992 we find that canadian affiliate sales to the united states are negatively correlated with canadian tariffs but u s parent sales to canadian affiliates have little association with canadian tariffs these results contradict the notion that canadian tariff reductions would lead to a hollowing out of canadian manufacturing we also find substantial heterogeneity in mnc responses to tariff changes within narrowly defined manufacturing industries overall bilateral trade liberalization is trade creating as u s mncs integrated their north american production such that canadian affiliates increased sales to the united states and reduced domestic sales

export platform foreign direct investment theory and evidence this paper proposes a model that accounts for export platform fdi a form of fdi that is common in the data but rarely discussed in the theoretical literature unlike the previous literature this paper s theory nests all the typical modes of supply including exports horizontal and vertical fdi horizontal and vertical export platform fdi the theory yields the testable hypothesis that a decrease in either inter regional or intra regional trade costs induces firms to choose export platform fdi the empirical analysis provides descriptive statistics that point to large proportions of third country exports of us fdi and an econometric analysis whose results are in line with the model s predictions the paper suggests policy implications for nations seeking to attract fdi

the opportunity criterion consumer sovereignty without the assumption of coherent preferences this paper proposes a formulation of consumer sovereignty for use in normative economics which does not presuppose individuals preferences to be coherent the fundamental intuition that opportunity and responsibility have moral value is formalised as a responsibility criterion for assessing opportunities in an economic system a model of an exchange economy is presented in which rational arbitrageurs compete to make profits by trading with non rational consumers in equilibrium this economy satisfies the responsibility criterion one interpretation of this result is that in a competitive environment the overall effects of money pumps are benign even if individuals preferences are persistently incoherent

regional tax coordination and foreign direct investment this paper analyses the effects of a regionally coordinated profit tax or location subsidy in a model with three active countries one of which is not part of the union and a globally mobile firm we show that regional coordination can lead to two types of welfare gain first for investments that would take place in the union in the absence of coordination a coordinated tax increase can transfer location rents from the firm to the union second by internalising all of the union s benefits from foreign direct investment a coordinated tax reduction can attract more welfare enhancing investment than when member states act in isolation depending on which motive dominates tax levels may thus rise or fall under regional coordination

demand for grazing on public lands a disequilibrium approach a demand function for grazing on western public rangelands is estimated since the federal government sets the grazing fee and rations the quantity of animal unit months aums a disequilibrium market model is developed the estimate of own price elasticity of demand 0 178 suggests a 0 82 percent revenue gain for a 1 percent fee increase results show that most western states experienced excess supply of aums since the mid 1980s suggesting a relatively high fee the levels of demand and effective supply vary substantially across states this implies that state or region specific factors should be incorporated in setting the grazing fee

trade factor prices and the gains from trade with increasing returns to scale existing analyses seem to suggest that national increasing returns to scale are not a very useful tool for analysing trade owing to problems such as multiple equilibria and the tendency towards complete specialization the purpose of this paper is to construct a model in which there are in fact determinant relationships among country size the direction of trade the gains from trade and international factor price differences in the model differences in country size determine the direction of trade which in turn determines factor price differences and limits the possible distribution of the gains from trade commerce international prix des facteurs de production et les gains de l change dans un contexte de rendements croissants a l echelle les analyses conventionnelles semblent suggerer que les rendements croissants h l 6chelle au niveau national ne constituent pas une avenue prometteuse dans l analyse du commerce international parce que de tels rendements creent une presomption en faveur de la specialisation complete et conduisent a des situations d 6quilibres multiples le but de ce m6moire est de construire un mod le dans lequel il existe des rapports determinants entre la dimension du pays la direction des 6changes les gains de l echange et les differentiels internationaux entre les prix des facteurs de production dans ce mod le les differences entre les pays en termes de dimension d6terminent la direction du commerce international laquelle d6termine le differentiel entre les prix des facteurs de production et limite l eventail des r6partitions possibles des gains de l echange

multinationals multi plant economies and the gains from trade a general equilibrium model of a multinational enterprise based on economies of multi plant operation is developed these economies are modelled as arising from the existence of a joint input whose productivity in each production facility is independent of the number of facilities maintained by a firm the multinational thus offers the world increased technical efficiency by eliminating the duplication of the joint input that would occur with independent national firms since this technical efficiency may come at the expense of increased market power the full determinants of home country host country and world welfare are considered

export oriented fdi in the uk it is well known that the performance of foreign firms compared to domestic companies is superior with respect to employment wages and productivity in this paper we detail the export behaviour of foreign affiliates in the united kingdom relative to indigenous firms our findings show that foreign firms are more likely to export and when they do so they are more export intensive and overall contribute disproportionately to total manufacturing exports from the uk while firm level advantages explain some of these differences in export behaviour strategic considerations dominate where these include the differential in costs productivity and market size between the uk and foreign countries that is both horizontal and vertical motives can be found for the use of the uk as an export platform by foreign firms copyright 2004 oxford university press

does the quality of investment protection affect fdi flows to developing countries evidence from latin america studies on the impact of international investment agreements iias including bilateral investment treaties bits on foreign direct investment fdi inflows have been inconclusive this paper contributes to the debate about the effectiveness of iias using an original database that differentiates between investment agreements according to the quality of investor protection and which covers a wide variety of trade and investment agreements signed and ratified in the americas we find evidence that in the least likely case of south south fdi flows high quality international investment treaties have a demonstrable effect on foreign direct investment inflows moreover international investment agreements appear to be most effective in a context of deeper economic integration that is they work better when they provide higher quality protection to investors and when they are combined with other preferential economic integration agreements such as trade agreements

endogenous r d and foreign direct investment in international oligopolies abstract this paper examines the impact of the firms mode of foreign expansion on the incentive to innovate as well as the effects of r d activities and technological spillovers on the firms international strategy we consider a two country imperfect competition model where the firms face three different type of decisions how to expand abroad how much to spend on r d and how much to sell in each market market structure is endogenously determined as the equilibrium solution of a three stage game it is shown that the firm that invests more in research is the one which is a mne while the rival is an exporter the results indicate that there is a positive relationship between multinational expansion and r d investment and that in turn investment in research increases the likelihood of multinational expansion the value of the spillover parameter can also be an important determinant of firms international strategy

multinational firms and the theory of international trade and investment tinational corporation in the arena of economic activity and political influence trade theorists have either ignored it or expressed unguarded skepticism at the ability of the conventional trade models to successfully capture and analyze the features of this new phenomenon the purpose of this paper is twofold first by building upon the contribution by richard caves we will show that the traditional trade models can be adapted in a way that preserves most if not all of the attributes introduced by international firms 2 second we will conduct a comparative statics analysis to explore the implications of tariffs and taxes for resource allocation and international capital movements our results here confirm what has already been well established in myriad empirical studies that maturation of the international firm has vastly increased economic interdependence among trading countries and that few nations can eschew the ripples caused by economic policies of other nations 3

economies of scale and market structure in international grain trade a large body of literature has examined international grain trade in imperfectly competitive models the article develops a two stage duopoly model that considers a private trader and a state trading enterprise ste competing on a foreign market the key difference between the private trader and the ste is their international organization while the ste makes use of external agents to export the private firm may choose to internalize international transactions the game is solved for different modes of competition and under both assumptions of homogeneous and differentiated products in order to assess how these assumptions affect the outcome of the game the results of the game are examined by using numerical examples the analysis shows that external shocks on export markets may result in a change of market structure and consequently of market shares these effects depend on the initial market structure furthermore the degree of product differentiation and the assumed mode of competition significantly affect the relative values of transaction and fixed costs at which the market structure changes

the impact of eu preferential trade agreements on foreign direct investment although north south preferential trade agreements ptas are expected to affect foreign direct investment fdi there is not much evidence to date on the impact of eu ptas on the pattern of fdi the aim of this study is to assess the impact of eu ptas on the outward stocks of fdi of the eu we estimate a model based on the knowledge capital theory of the multinational enterprise over the period 1995 2005 using a sample of 173 host countries explanatory variables include measures of the level of bilateral protection and a dummy to capture the impact of deep integration provisions of ptas a dynamic panel model with fixed effects is used in order to take into account the dynamic behaviour of fdi and the heterogeneity bias results show that eu fdi is both horizontal and vertical the level of eu protection affects fdi negatively while the impact of the tariffs applied by host countries varies across groups of partner countries deep integration provisions affect eu fdi positively

dutch books and conditional probability an oddsmaker who does not update odds in accordance with conditional probability can be subjected to a sure loss such a losing situation is called a dutch book this is often presented as an argument for setting odds in accordance with conditional probability the authors point out that if the strategic aspects of oddsmaking are taken into account choice of odds is a strategic choice in games against bettors then it is possible that in the equilibrium of the game posted odds need not be updated correctly this calls into question the role of such arguments in the foundations of decision theory copyright 1994 by royal economic society

does economic integration cause foreign direct investment the authors analyze the effect of economic integration on oligopolists international trade and foreign direct investment activities using a three country three firm model increased country size leads to dispersed foreign direct investment while improved market accessibility leads to export platform foreign direct investment increased intraregional market accessibility prompts outside firms to invest in the regional bloc reducing product prices profits of intrabloc firms and increasing total surplus integrating economies are more likely to gain from improving intraregional market accessibility than from tougher external trade policy and may wish to offer investment incentives to encourage foreign direct investment by outside firms copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

factor movements and commodity trade as complements abstract several models are presented in which factor mobility leads to an increase in the volume of world trade the models share the common characteristic that the basis for trade is something other than differences in relative factor endowments these alternative bases for trade include returns to scale imperfect competition production and factor taxes and differences in production technology taken together the models suggest a more general idea the widely held notion that trade in goods and factors are substitutes is in fact a rather special result which is a general characteristic only of factor proportions models

regional economic integration and geographic concentration of multinational firms abstract a number of theoretical studies have predicted that preferential trade agreements ptas raise outside multinationals incentive to invest in the participating countries especially in those that are integrated with larger markets and have lower production costs the hypothesis has however not been tested empirically this paper addresses the issue by estimating the impact of ptas on countries ability to attract multinationals the evidence is broadly consistent with expectations the formation of ptas leads to an increase in fdi by outside multinationals but the effect varies sharply with the size of integrated markets and countries comparative advantage countries integrated with larger markets experience a greater increase in total and export platform fdi those with a higher labor endowment also attract more fdi especially in labor intensive industries but at the expense of their labor scarce pta partners

fdi in space spatial autoregressive relationships in foreign direct investment abstract there are a number of theoretical reasons why foreign direct investment fdi into a host country may depend on the fdi in proximate countries such spatial interdependence has been largely ignored by the empirical fdi literature with only a couple recent papers accounting for such issues in their estimation this paper conducts a general examination of spatial interactions in empirical fdi models using data on us outbound fdi activity we find that estimated relationships of traditional determinants of fdi are surprisingly robust to inclusion of terms to capture spatial interdependence even though such interdependence is estimated to be significant however we find that both the traditional determinants of fdi and the estimated spatial interdependence are quite sensitive to the sample of countries one examines

regional trading arrangements natural or supernatural members of the customs union the potential unfavorable effects arise from the introduction of distortions in the relative price between the goods of members and nonmembers in terms of classic customs union theory the trade off is between trade creation and trade diversion the entire exercise assumes that the firstbest solution of worldwide free trade is not attainable for political reasons thus the choice between a status quo of nondiscriminatory most favored nation mfn tariffs and a move to preferential trading arrangements pta s is an exercise in the theory of the second best this paper summarizes recent research by the authors we make an evaluation of the

preferential trade agreements and tax competition for foreign direct investment abstract this paper examines how free trade agreements and customs unions affect the location of foreign direct investment fdi and social welfare taking into account that governments may adjust taxes and external tariffs to compete for fdi conditions are identified under which a free trade agreement leads to fdi and under which this improves welfare the welfare effect is shown to depend on the relative size of efficiency gains in production and government revenue losses due to tax competition a free trade agreement may fail to induce welfare improving fdi creating a role for a customs union

diversification cost structure and the risk premium of multinational corporations we investigate theoretically and empirically the relationship between the geographic structure of a multinational corporation and its risk premium our structural model suggests two channels on the one hand multinational activity offers diversification benefits risk premia should be higher for firms operating in countries where shocks co vary more with the domestic ones second hysteresis and potential losses induced by fixed and sunk costs of production imply that risk premia should be higher for firms operating in countries where is costlier to enter our empirical analysis confirms these predictions and delivers a decomposition of firm level risk premia into indi

measuring the interdependence of multinational firms foreign investments earlier work found evidence for geographic linkages of aggregate foreign direct investment across countries and country pairs from a theoretical point of view such linkages at the macroeconomic level may root in between firm as well as within firm linkages and originate from information spillovers across or within firms in exploring unknown markets and vertical linkages between production plants across different locations within the firm we use data on the universe of german multinational enterprises mnes to empirically explore how marginal investments at one foreign affiliate depend on investments at other affiliates within the same mne the empirical approach employs two channels or modes of cross affiliate interdependence mere geography capturing horizontal linkages through correlated learning and horizontal competition within the firm and input output relationships within or across industries which capture vertical linkages adding to earlier findings at the aggregate level we find evidence of a significant interdependence of investments within the firm in the firm level data at hand vertical linkages appear to be more important than horizontal ones investments at one location tend to stimulate investments at other locations of the same mne particularly if input linkages are strong the opposite seems to be true for output linkages beyond vertical linkages mere geographic proximity matters only to a minor extent this suggests that evidence of linkages through geographic closeness at aggregate data levels accrue mainly to reasons of vertical linkages within networks of affiliates jel c31 d22 f21 f23 f68 g31 h32

an economic analysis of alternative grazing fee systems congress called for an evaluation of potential grazing fees and fee alternatives by 1985 this study contributes to that evaluation and constitutes an economic evaluation of the current and seven other fee systems fee systems are evaluated for total welfare income distribution future discrepancies between fees and forage values public administration cost usage potential administrative feasibility and data requirements these criteria are found to be mutually inconsistent particularly for welfare future discrepancies public administration cost and income distribution fee systems most consistent with these criteria involve ones based on private land lease rates government administration costs or competitive bidding

tariff jumping and joint ventures it is well known that high tariffs tend to induce foreign direct investment fdi by encouraging the investors to jump the tariff wall this paper examines the economic interaction among tariffs fdi and international joint ventures ijv we show that in the presence of a strong local competitor even if opening a fully owned subsidiary is not profitable to a foreign firm the foreign firm may still enter the host country market through ijv however ijv is not profitable for sufficiently high tariff rates hence we argue that liberal trade policies may attract foreign investments through the formation of joint ventures

reconsiderations in the foundations of decision under uncertainty an explosion has occurred during the past decade in the foundations of decision making under risk and uncertainty the long dormant challenges of allais i 953a b to the von neumann morgenstern i944 independence axioms of allais and of ellsberg 1 96 i to savage s i 954 sure thing principle and of may 1954 and tversky i969 to the transitivity of preferences have sprung to new life through widespread empirical corroboration in the wake of the new evidence an array of representations of preferences has been proposed to accommodate failures of one or more of the traditional axioms 2 although some new models are solely descriptive kahneman and tversky 1979 others have normative interest as competitors of the von neumannmorgenstern expected utility theory quiggin i982 machina i982 chew i982 i983 fishburn i982 or of savage s subjective probability expected utility theory bell i982 loomes and sugden i982 i987 schmeidler i984 gilboa i985 luce and narens i985 fishburn i984 b i986b one benefit of recent foundational work is a deeper understanding of the content and implications of expected utility coupled with a new appreciation of the underlying issues that divided decision theorists a generation ago i am thinking especially of the 1952 paris colloquium on decision under uncertainty allais 1979 pp 446 7 at which allais confronted defenders of expected utility de finetti friedman marschak samuelson savage with his insistence on riskless measurement of the utility of wealth and violations of independence axioms the colloquium appears to have ended in a standoff but enabled each side to sharpen its own position

on money pumps abstract the question of whether money pump arguments justify standard consistency assumptions about behavior has remained unresolved partly because of the absence of an appropriate analytical framework we present a new framework which fills this gap provide a formal definition of invulnerability to money pumps and formulate a requirement of maximal opportunism we show that behavior which satisfies none of the standard consistency assumptions can be both invulnerable and maximally opportunist we present two conditions which combined with maximal opportunism imply the existence of a choice function rationalized by an ordering and satisfying the sure thing principle journal of economic literature classification numbers b41 c73 d81
