have trading rule profits in the currency markets declined over time abstract previous studies have reported mixed results regarding the success of technical trading rules in currency markets abnormal returns were observed in many studies using data up to the mid 1980s while more recent studies generally report less success for technical trading rules this paper tests whether moving average trading rule profits have declined over the period from 1971 to 2000 if so previous profits may represent a temporary inefficiency that has since been eliminated in the currency markets the hypothesis is tested using 18 exchange rate series over a longer time period than in previous studies rules are optimized for successive 5 year in sample periods from 1971 to 1995 and tested over subsequent 5 year out of sample periods results show that risk adjusted trading rule profits have declined over time from an average of over 3 in the late 1970s and early 1980s to about zero in the 1990s thus market inefficiencies reported in previous studies may have been only temporary inefficiencies

revenue maximizing dutch auctions with discrete bid levels abstract this paper is concerned with setting a predetermined number of bid levels in a dutch auction to maximize the auctioneer s expected revenue as a departure from the traditional methods used by applied economists and game theorists a novel approach is taken in this study to tackle the problem by formulating the auctioning process as a constrained nonlinear program and applying standard optimization techniques to solve it aside from proposing respective closed form formulae for computing the optimal bid levels and the auctioneer s maximum expected revenue we also show that the bid decrements should be increasing if there are two or more bidders in the dutch auction additionally the auctioneer s maximum expected revenue increases with the number of bidders as well as the number of bid levels finally managerial implications of the key findings as well as limitations of this research work are discussed

international institutions and the volatility of international trade during the past half century states have established a large number of international trade institutions both multilateral and regional in scope the existing literature on this topic emphasizes that these agreements are chiefly designed to liberalize and increase the flow of overseas commerce yet such institutions have another function that has been largely ignored by researchers namely reducing volatility in trade policy and trade flows exposure to global markets increases the vulnerability of a country s output to terms of trade shocks governments seek to insulate their economies from such instability through membership in international trade institutions particularly the world trade organization wto and preferential trading arrangements ptas we hypothesize that these institutions reduce the volatility of overseas commerce we further hypothesize that because market actors prefer price stability trade institutions increase the volume of foreign commerce by reducing trade variability this article conducts the first large scale multivariate statistical tests of these two hypotheses using annual data on exports for all pairs of countries from 1951 through 2001 the tests provide strong support for our arguments ptas and the wto regime significantly reduce export volatility in so doing these institutions also increase export levels

real exchange rates and time varying trade costs this paper re examines the empirical modeling of purchasing power parity ppp deviations in the presence of commodity market frictions first we show that a specific type of smooth transition models can closely approximate the functional form of the theoretical adjustment mechanism derived by dumas 1992 dynamic equilibrium and the real exchange rate in a spatially separated world review of financial studies 5 2153 180 for the case of constant as well as changing trade costs second we develop for the first time an empirical model of the real exchange rate which allows for changes in the degree of market integration by employing a long span of data on the dollar sterling real exchange rate and a micro founded proxy for trade frictions we provide novel evidence of a significant relationship between the persistence of the real exchange rate and the level of trade costs this finding suggests that both the difficulty of detecting ppp and the extend of rogoff s puzzle vary over time with the degree of trade restrictiveness finally we highlight policy repercussions of our results

the not so generalized effects of the generalized system of preferences we use an empirical gravity equation approach to study how nonreciprocal trade preferences nrtps enacted mainly through the generalized system of preferences affect the exports of the beneficiary nations in line with existing studies the average trade effect stemming from nonreciprocal preferences is highly unstable across specifications however once we allow for heterogeneous effects results become robust and economically important specifically nrtps have a strong effect on the exports of beneficiaries when they are members of the world trade organization and are very poor not so poor beneficiaries also expand foreign sales but only if they are not wto members for all others the average export effects of nrtps are mute

economists capitalists and the making of globalization north american free trade in comparative historical perspective why did globalization happen current explanations point to a variety of conditions under which states have made the free market policy changes driving international economic integration since the 1980s such accounts disagree however about the key actors involved this article provides a reconciliation showing how two different combinations of actors and two different political economic pathways have led to globalization in recent decades in developed countries mobilization by business has been central elsewhere technocrats both constrained and empowered by international finance have pursued globalization more independently of business in both contexts economists technical authority has helped legitimate liberalization despite the limited diffusion of their ideas the article validates and elaborates this model using a comparative historical study of how the united states canada and mexico proposed negotiated and ratified agreements for free trade in north america

the institutional roots of american trade policy politics coalitions and international trade the 1934 reciprocal trade agreements act rtaa changed the structure of the making of u s trade policy and made possible a dramatic reduction in tariffs the authors demonstrate that the key institutional innovation in the rtaa was its mandate to lower tariffs through reciprocal agreements with foreign nations the expansion of exports under the rtaa enhanced political support for increasingly lower u s tariffs evidence that export interests were positively associated with congressional votes for free trade supports this view

an exclusive country club the effects of the gatt on trade 1950 94 using data on bilateral trade flows from both before and after world war ii this article examines the impact of the general agreement on tariffs and trade on trade between its members and on the system of interwar trade blocs it shows that the distribution of the benefits produced by the gatt was much more highly skewed than conventional wisdom assumes the article also shows that the gold commonwealth reichsmark and exchange control blocs exerted positive and significant effects on trade after 1945 the authors attribute these effects to the bargaining protocol that governed successive rounds of gatt negotiations the signature element of the postwar trade regime

the value of trade agreements in the presence of political pressures an argument often heard in favor of trade agreements is that by committing to free trade a government can credibly distance itself from domestic lobbies but several existing models of endogenous protection suggest that governments have no interest in foreclosing interest group pressures since governments derive rents from the political process we develop a small country model in which factors are sector specific in the short run but mobile in the long run we show that in this setting a government may be worse off in the political equilibrium than under commitment to free trade and hence it may value a trade agreement

managing online auctions current business and research issues the internet s computational power and flexibility have made auctions a widespread and integral part of both consumer and business markets though online auctions are a multi billion dollar annual activity with a growing variety of sophisticated trading mechanisms scientific research on them is at an early stage this paper analyzes the current state of management science research on online auctions it develops a broad research agenda for issues such as the behavior of online auction participants the optimal design of online auctions the integration of auctions into the ongoing operation of firms and the use of the data generated by online auctions to inform future trading mechanisms these research areas will draw from applied and theoretical work spanning management science economics and information systems

market timing a test of a charting heuristic abstract we implement a graphical or charting heuristic the bull flag which accepts a particular pattern of historical prices as a signal for a future market price increase test it with several years of new york stock exchange composite index history and find positive results the results support the validity of technical analysis for stock market price prediction and fail to confirm the efficient markets hypothesis

bilateral treaties and the most favored nation clause the myth of trade liberalization in the nineteenth century textbook accounts of the anglo french trade agreement of 1860 argue that it heralded the beginning of a liberal trading order this alleged success holds much interest from a modern policy point of view for it rested on bilateral negotiations and most favored nation clauses with the help of new data on international trade the ricardo database the authors provide empirical evidence and find that the treaty and subsequent network of mfn trade agreements coincided with the end of a period of unilateral liberalization across the world they also find that it did not contribute to expanding trade at all this is contrary to a deeply rooted belief among economists economic historians and political scientists the authors draw a number of policy lessons that run counter to the conventional wisdom and raise skepticism toward the ability of bilateralism and mfn arrangements to promote trade liberalization

a dual dutch auction in taipei the choice of numeraire and auction form in multi object auctions with bundling abstract in taipei we observed a dual dutch fish auction like a conventional dutch auction with bundling but with reversed roles of price and quantity we study dual and conventional auctions with symmetric independent private values when agents utilities are linear in money but strictly concave in fish with known buyers values conventional and dual auctions english or dutch are equivalent with values known to buyers but not the seller the seller prefers conventional auctions with private values the seller can prefer a dual dutch or a conventional english or dutch auction but prefers all three to a dual english auction

trading volume and cross autocorrelations in stock returns this paper finds that trading volume is a significant determinant of the lead lag patterns observed in stock returns daily and weekly returns on high volume portfolios lead returns on low volume portfolios controlling for firm size nonsynchronous trading or low volume portfolio autocorrelations cannot explain these findings these patterns arise because returns on low volume portfolios respond more slowly to information in market returns the speed of adjustment of individual stocks confirms these findings overall the results indicate that differential speed of adjustment to information is a significant source of the cross autocorrelation patterns in short horizon stock returns both academics and practitioners have long been interested in the role played by trading volume in predicting future stock returns 1 in this paper we examine the interaction between trading volume and the predictability of short horizon stock returns specifically that due to lead lag cross autocorrelations in stock returns our investigation indicates that trading volume is a significant determinant of the cross autocorrelation patterns in stock returns 2 we find that daily or weekly returns of stocks with high trading volume lead daily or weekly returns of stocks with low trading volume additional tests indicate that this effect is related to the tendency of high volume stocks to respond rapidly and low volume stocks to respond slowly to marketwide information

the gatt in historical perspective the transformation of the general agreement on tariffs and trade gatt into the world trade organization wto on january 1 1995 provides an opportune moment to take stock of the gatt s achievements and shortcomings alongside those of its 50 year old sister international institutions set up at bretton woods it is temptingly easy to attribute the astounding postwar economic expansion particularly when set against the turbulent interwar period when multilateral efforts to contain protectionist pressures failed miserably to the economic policies embodied in the gatt and to the initial stability provided by the bretton woods institutions yet a closer look at precisely what the gatt accomplished in its first decade suggests that trade liberalization under its auspices alone is far from sufficient to explain the postwar economic boom

the politics of foreign direct investment into developing countries increasing fdi through international trade agreements the flow of foreign direct investment into developing countries varies greatly across countries and over time the political factors that affect these flows are not well understood focusing on the relationship between trade and investment we argue that international trade agreements gatt wto and preferential trade agreements ptas provide mechanisms for making commitments to foreign investors about the treatment of their assets thus reassuring investors and increasing investment these international commitments are more credible than domestic policy choices because reneging on them is more costly statistical analyses for 122 developing countries from 1970 to 2000 support this argument developing countries that belong to the wto and participate in more ptas experience greater fdi inflows than otherwise controlling for many factors including domestic policy preferences and taking into account possible endogeneity joining international trade agreements allows developing countries to attract more fdi and thus increase economic growth

the declining price anomaly abstract data from wine auctions indicate that identical products sold sequentially typically follow a decreasing pattern of prices known as the declining price anomaly this is explained for both first and second price auctions by appealing to risk averse bidders earlier bids are then equal to expected later prices plus a risk premium associated with the risky future price we show that this logic rests on the assumption of nondecreasing absolute risk aversion which is necessary for pure strategy equilibrium bidding functions to exist thus decreasing absolute risk aversion implies ex post inefficiency with positive probability data from wine auctions are used to confirm the existence of the declining price anomaly journal of economic literature classification numbers d43 d44 d81 d82 l81

the reductionist gamble open economy politics in the global economy international political economy ipe should transition to third wave scholarship because open economy politics oep which dominates current american ipe scholarship can generate inaccurate knowledge oep can produce inaccurate knowledge because it studies domestic politics in isolation from international or macro processes this methodological reductionism is often inappropriate for the phenomena ipe studies because governments inhabit a complex social system as a result the political choices that oep strives to explain are typically a product of the interplay between domestic politics and macro processes when oep omits causally significant macro processes from empirical models the models yield biased inferences about the domestic political relationships under investigation although scholars tolerated such errors when the gains from oep were large these errors are less tolerable now that oep has matured consequently the field should transition toward research that is nonreductionist problem driven and pluralistic

the statistical distribution of exchange rates empirical evidence and economic implications the abundant evidence that changes in exchange rates have distributions with fatter tails than the normal distribution has led researchers to consider non normal distributions including the student the stable paretian and mixtures of distributions this paper compares the empirical fits of three non normal candidates and the normal distribution for daily changes in the logarithms of exchange rates using maximum likelihood estimation of the parameters and chi square goodness of fit tests the student and mixture of two normals provide the best fits but there is evidence that the distribution parameters may vary over time

resource allocation models with risk aversion and probabilistic dependence offshore oil and gas bidding bidding for offshore u s oil and gas leases is a major corporate resource allocation problem involving enormous uncertainties and very high stakes this paper presents two new operationally useful decision analysis models to aid in bidding for oil and gas leases they are unique in that they consider risk aversion and probabilistic dependence among the values of the leases with both bid levels and partnership shares as continuous decision variables they are suitable for use in evaluating proposed bidding policies or as objective functions in optimization formulations practicality of their data requirements is evidenced by use of one of the models for several years in a major oil company comparison of optimal solutions to these models on a small example using actual oil company data demonstrates the importance of taking risk aversion and probabilistic dependence into account and provides insight into the adequacy of independence and conditional dependence as approximations for dependence these results are pertinent to other real world allocation problems that share many of the characteristics of bidding problems such as r d funds allocation

revenue ranking of discriminatory and uniform auctions with an unknown number of bidders an important managerial question is the choice of the pricing rule we study whether this choice depends on the uncertainty about the number of participating bidders by comparing expected revenues under discriminatory and uniform pricing within an auction model with affiliated values stochastic number of bidders and linear bidding strategies we show that if uncertainty about the number of bidders is substantial then the discriminatory pricing generates higher expected revenues than the uniform pricing in particular the first price auction might generate higher revenues than the second price auction therefore uncertainty about the number of bidders is an important factor to consider when choosing the pricing rule we also study whether eliminating this uncertainty i e revealing the number of bidders is in the seller s interests and discuss the existence of an increasing symmetric equilibrium

politics institutions and trade lessons of the interwar era recent studies cast doubt on the value added of international trade agreements and institutions using a new data set that consists of about 35 000 observations on the trade of fifty four nations between 1919 and 1938 we examine whether this skepticism also applies to the infamous interwar trade blocs traditional historical accounts attribute to them a large drop in international trade and a rise in the political tensions that would later erupt in world war ii in this study we show that no bloc raised trade among its members as a whole or decreased trade between members and nonmembers however our findings are not wholly consistent with the skepticism recent studies express we argue that conflicts of interest among the great powers encouraged the emergence of the bloc system and also gave rise to intrabloc trade shifts consistent with the political interests of their great power hubs the political military alliances these conflicts created also reduced trade between their signatories and we argue more generally that the causal chain runs from politics to trade as a result measuring only the effect of agreements and institutions on aggregate trade between their members can generate inaccurate estimates of their value added

trade blocs currency blocs and the reorientation of world trade in the 1930s we analyze the impact of commercial and financial policies on the reorientation of trade in the 1930s we report evidence that commercial policies attenuated prior connections between income growth and trade and that exchange rate instability marginally discouraged international trade in contrast the tendency toward regionalization commonly ascribed to the formation of trade and currency blocs was already evident to a considerable extent prior to the regional policy initiatives of the 1930s this reorientation is more properly attributed to ongoing historical forces such as commercial and financial links between countries forged over many years

does flexibility promote cooperation an application to the global trade regime do flexibility provisions in international agreements clauses allow ing for legal suspension of concessions without abrogating the treaty promote coop eration recent work emphasizes that provisions for relaxing treaty commitments can ironically make states more likely to form agreements and make deeper conces sions when doing so this argument has particularly been applied to the global trade regime the general agreement on tariffs and trade gatt and its successor the world trade organization wto yet the field has not produced much evidence bearing on this claim our article applies this claim to the global trade regime and its chief flexibility provision antidumping in contrast to prior work this article explic itly models the endogeneity and selection processes envisioned by the theory we find that states joining the wto are more likely to adopt domestic antidumping mech anisms likewise corrected for endogeneity states able to take advantage of the regime s principal flexibility provision by having a domestic antidumping mecha nism in place are significantly more likely to 1 join the wto 2 agree to more tightly binding tariff commitments and 3 implement lower applied tariffs as well

selecting optimal selling format of a product in b2c online auctions with boundedly rational customers abstract the advancement of internet technology has enabled new formats for selling products in the b2c online auctions at present on the major online auction sites there exist three popular selling formats namely the posted price pure auction and buy price auction formats it is an important decision problem for a firm to select the most profitable format to sell its products through the internet the customer behavior is of course a crucial element of the decision process to the best of our knowledge most models available today assume that customers are perfectly rational to better understand the decision process in this paper we incorporate the concept of bounded rationality into consideration we first present a behavior choice function to characterize the behavior of the customers with bounded rationality then corresponding to each selling format we construct a revenue model based on the bounded rationality for analysis finally we conduct some elaborate computational experiments to investigate the performance of each revenue model for developing new managerial insights our computational results clearly demonstrate how the bounded rationality of customer behavior affects the choice of a preferable selling format for a b2c firm in an online auction

why do some countries get better wto accession terms than others the process by which countries accede to the world trade organization wto has become the subject of considerable debate this article takes a closer look at what determines the concessions the institution requires of an entrant in other words who gets a good deal and who does not i argue that given the institutional design of accession proceedings and the resulting suspension of reciprocity accession terms are driven by the domestic export interests of existing members as a result relatively greater liberalization will be imposed on those entrants that have more valuable market access to offer upon accession something that appears to be in opposition to expectations during multilateral trade rounds where market access functions as a bargaining chit the empirical evidence supports these assertions looking at eighteen recent entrants at the six digit product level i find that controlling for a host of country specific variables as well as the applied protection rates on a given product prior to accession the more a country has to offer the more it is required to give moreover i show how more democratic countries in spite of their greater overall depth of integration exhibit greater resistance to adjustment in key industries than do nondemocracies finally i demonstrate that wealth exhibits a curvilinear effect on the one hand institutionalized norms lead members to exercise observable restraint vis a vis the poorest countries on the other hand the richest countries have the greatest bargaining expertise and thus obtain better terms the outcome as i show using a semi parametric analysis is that middle income countries end up with the most stringent terms and have to make the greatest relative adjustments to their trade regimes

the perversity of preferences gsp and developing country trade policies 1976 2000 industrial countries maintain special tariff preferences namely the generalized system of preferences gsp for imports from developing countries critics have highlighted the underachieving nature of such preferences but developing countries continue to place the gsp at the heart of their agenda in multilateral negotiations what effect do such preferences have on a recipient s own trade policies the authors develop and test a simple theoretical model of a small country s trade policy choice using a dataset of 154 developing countries from 1976 through 2000 they find that countries removed from the gsp adopt more liberal trade policies than those remaining eligible the results corrected for endogeneity and robust to numerous alternative measures of trade policy suggest that developing countries may be best served by full integration into the reciprocity based world trade regime rather than continued gsp style special preferences

policy diffusion of emission standards is there a race to the top in a dramatic example of policy diffusion the past three decades have witnessed the spread of automobile emission standards throughout the world contrary to fears that global competition would produce a race to the bottom there appears to be a race to the top not only among rich countries but also among poor ones using econometric analysis of the adoption of automobile emission standards over the past twenty years for 129 countries the author argues that this global diffusion results from countries efforts to stay competitive in the international market due to the pressure from importing countries that have adopted stringent emission standards even developing countries have rapidly moved to adopt rich country standards the evidence shows that adoption of automobile emission standards correlates with an increase in the total value of automobile exports under some conditions economic incentives in a global market can be a complement to environmental protection

exchange rates forecasting local or global methods exchange rates forecasters usually assume that local methods nearest neighbour dominate the global ones neural networks or genetic programming for example in this article first we use different generalizations of the standard nearest neighbours to predict the dynamic evolution of the yen us and pound sterling us exchange rates one period ahead second we compare our results with those employing global methods such as neural networks genetic programming data fusion and evolutionary neural networks finally we find out the existence of predictable structures periods ahead our results reveal a slightly but significant forecasting ability for one period ahead which is lost when more periods ahead are considered and no important predictive differences between local and global methods have been found

oil curse economic growth and trade openness an important economic paradox in the economic literature is that countries with abundant natural resources are poor in terms of real gross domestic product per capita this paradox known as the resource curse is contrary to the conventional intuition that natural resources help to improve economic growth and prosperity using panel data for 95 countries this study revisits the resource curse paradox in terms of oil resources abundance for the period 1980 2017 in addition the study examines the role of trade openness in influencing the relationship between oil abundance and economic growth the study finds trade openness is a possible avenue to reduce the resource curse in our sample trade openness reduces oil curse by around 25 trade openness allows countries to obtain competitive prices for their resources in the international market and access advanced technologies to extract resources more efficiently therefore natural resource rich economies can reduce the resource curse by increasing exposure to international trade

do we really know that the wto increases trade comment in a recent article in the american economic review andrew k rose 2004 finds that countries belonging to the general agreement on tariffs and trade gatt and its successor the world trade organization wto did not trade more than countries that abstained from membership a vast literature on the gatt and the wto presupposes that these organizations were important but until rose there were few systematic efforts to test the assumption that membership increased trade rose s contribution is striking because he assembles a large dataset performs a myriad of analyses and uncovers scant evidence that the gatt and the wto had any impact rose describes his negative findings as an interesting mystery 112 the solution to this mystery lies in understanding who actually participated in the gatt we show that rose has overlooked a large proportion of countries to which the agreement applied and mistakenly classified them as nonparticipants when in fact they had rights and obligations under the agreement this causes a downward bias in his estimates of the gatt s effect on trade because his gravity regressions

the emperor has no clothes the limits of opec in the global oil market most scholars and policymakers believe opec can and does influence the price of oil by acting as a cartel this paper argues that most of the conventional wisdom about opec is wrong opec rarely if ever influences the oil production rate in its member states further opec has almost no lasting impact on world prices except under rare conditions there was one occasion on which opec did have a significant impact on world oil prices namely the 1973 oil crisis but opec s role in the event has been greatly misunderstood the circumstances of the crisis were highly exceptional making it unlikely that the organization could ever have a similar impact on world oil prices again this paper seeks to correct the misunderstanding about opec s role and replace it with a better understanding of the organization i argue that opec is dysfunctional as a cartel as it has little or no causal impact on its members choices about production levels or investment in production capacity opec s role is obscured in part by the complexity of the world oil market and in part by misdirection by policymakers especially within opec many scholars especially economists have argued that opec should be understood as a cartel designed to solve a prisoner s dilemma pd coordination game yet opec s persistence is better understood as a widespread failure to update beliefs about the organization a failure that is driven by information asymmetry and politics the fact that such a widespread belief about the world s most important commodity market could be wrong can help us better understand international regimes

on the role of discrete bid levels in oral auctions abstract bids in oral auctions are restricted to discrete levels this paper both examines the choice of levels at which bids will be allowed and also presents a simple model of the role of the discrete levels in bidding strategy we consider two different distributions of bidders values identifying cases in which revenue is maximized by increasing intervals by constant intervals and by decreasing intervals moreover conditions under which the choice of bid levels that maximizes bid taker revenue also maximizes economic efficiency are developed we present a model of the economic trade off between auction duration and step size we consider the previously undiscussed issue of when economically motivated bidders should skip bid levels and when they should merely make minimum advances and develop a model in which it is equilibrium behavior always to make the minimum allowed advance

institutions in international relations understanding the effects of the gatt and the wto on world trade the general agreement on tariffs and trade gatt and the world trade organization wto have been touted as premier examples of international institutions but few studies have offered empirical proof this article comprehensively evaluates the effects of the gatt wto and other trade agreements since world war ii our analysis is organized around two factors institutional standing and institutional embeddedness we show that many countries had rights and obligations or institutional standing in the gatt wto even though they were not formal members of the agreement we also expand the analysis to include a range of other commercial agreements that were embedded with the gatt wto using data on dyadic trade since 1946 we demonstrate that the gatt wto substantially increased trade for countries with institutional standing and that other embedded agreements had similarly positive effects moreover our evidence suggests that international trade agreements have complemented rather than undercut each other an earlier version of this article was presented at the 99th annual meeting of the american political science association philadelphia august 28 31 2003 we thank tim buthe joanne gowa miles kahler andrew rose arthur stein richard steinberg and seminar participants at stanford university the university of chicago pipes the university of california los angeles the university of california san diego and the university of virginia for many helpful comments we especially thank claire adida ashley conner moonhawk kim erin krampetz james morrison mike nardis natan sachs rachel rubinfeld and jessica weeks for excellent research assistance we are grateful for financial support from the national science foundation career grant ses 0548285 to tomz the stanford center for international development and the vice provost for undergraduate education at stanford

estimating risk aversion from ascending and sealed bid auctions the case of timber auction data estimating bidders risk aversion in auctions is a challeging problem because of identification issues this paper takes advantage of bidding data from two auction designs to identify nonparametrically the bidders utility function within a private value framework in particular ascending auction data allow us to recover the latent distribution of private values while first price sealed bid auction data allow us to recover the bidders utility function this leads to a nonparametric estimator an application to the us forest service timber auctions is proposed estimated utility functions display concavity which can be partly captured by constant relative risk aversion

inertia and change in the constellation of international governmental organizations 1981 1992 hardly anyone expects public institutions to die yet a census reveals that fully one third of the international governmental organizations igos in existence in 1981 had in fact become defunct by 1992 most eastern bloc and many regional developing country organizations vanished or became inactive during this period a slightly larger number of new organizations was born not governments but other igos spawned most of the new offspring wealthy democratic countries increased their igo memberships while poor unstable countries increasingly dropped out this bifurcation was accompanied by greater reliance by all on a set of core universal membership institutions dominated by western values functionalism organizational ecology and realism each partly help us to understand these trends but leave important dynamics unexplained

on the profitability of technical trading rules based on artificial neural networks evidence from the madrid stock market in this paper we investigate the profitability of a simple technical trading rule based on artificial neural networks anns our results based on applying this investment strategy to the general index of the madrid stock market suggest that in absence of trading costs the technical trading rule is always superior to a buy and hold strategy for both bear market and stable market episodes on the other hand we find that the buy and hold strategy generates higher returns than the trading rule based on ann only for a bull market subperiod 2000 elsevier science s a all rights reserved

electricity market price forecasting based on weighted nearest neighbors techniques this paper presents a simple technique to forecast next day electricity market prices based on the weighted nearest neighbors methodology first it is explained how the relevant parameters defining the adopted model are obtained such parameters have to do with the window length of the time series and with the number of neighbors chosen for the prediction then results corresponding to the spanish electricity market during 2002 are presented and discussed finally the performance of the proposed method is compared with that of recently published techniques

a unified method for dynamic and cross sectional heterogeneity introducing hidden markov panel models conventional statistical methods for panel data are based on the assumption that unobserved heterogeneity is time constant despite the central importance of this assumption for panel data methods few studies have developed statistical methods for testing this assumption and modeling time varying unobserved heterogeneity in this article i introduce a formal test to check the assumption of time constant unobserved heterogeneity using bayesian model comparison then i present two panel data methods that account for time varying unobserved heterogeneity in the context of the random effects model and the fixed effects model respectively i illustrate the utility of the introduced methods using both simulated data and examples drawn from two important debates in the political economy literature 1 the identification of shifting relationships between income inequality and economic development in capitalist countries and 2 the effects of the gatt wto on bilateral trade volumes

linear non linear and essential foreign exchange rate prediction with simple technical trading rules abstract this paper investigates the predictability of spot foreign exchange rate returns from past buy sell signals of the simple technical trading rules by using the nearest neighbors and the feedforward network regressions the optimal choices for nearest neighbors hidden units in a feedforward network and the training set are determined by the cross validation method which minimizes the mean square error although this method is computationally expensive the results indicate that it has the advantage of avoiding overfitting in noisy environments and indicate that simple technical rules provide significant forecast improvements for the current returns over the random walk model

does international law promote the peaceful settlement of international disputes evidence from the study of territorial conflicts since 1945 in this article we explain the role of international law in the resolution of territorial disputes from 1945 to 2000 in doing so we focus on three outcomes of interest first when do states choose to revise the territorial status quo through negotiations instead of force second when are states able to reach a final settlement third when do states prefer a process of legal dispute resolution i e adjudication or arbitration to bilateral negotiations to answer these questions we argue that when the legal principles relevant to the dispute are unambiguous and clearly favor one side a law based focal point will emerge this focal point in turn facilitates the settlement process by helping leaders overcome distribution problems a central obstacle in reaching a final agreement we find strong and consistent empirical support for our hypotheses regarding international law and peaceful dispute resolution i s a legal advantage an important source of bargaining leverage for state leaders as they negotiate over security issues in international disputes does international law provide the foundation for the peaceful settlement of security related disputes in a system defined by anarchy there are reasons to question whether international law can play a central role in the orderly and peaceful resolution of disputes when security issues are at stake for leaders indeed many would argue that the shadow of military power is an ever present influence over such bargaining processes and that international law is therefore not a viable substitute for military strength and credible threats of force to secure the peace as a result although law may have an important role to play in governing international economic relations e g goldstein rivers and tomz 2007 simmons and hopkins 2005 von stein 2005 zangl 2008 where the parties will often have strong incentives to coordinate their behavior the role of law in settling disagreements over security related issues is a far more contentious question among scholars and policy makers in such situations leaders will often have divergent preferences over how the issue should be resolved making the identification of a mutually acceptable solution difficult the security aspect of the dispute compounds this problem because leaders will be reluctant to sign any agreement that they believe might decrease

slow dutch auctions theorists have long believed that dutch auctions are strategically equivalent to standard sealed bidding however in recent controlled experiments with actual dutch and sealed bid internet auctions of collectibles the dutch auctions produced significantly more revenue we believe that this happened in part because the internet dutch auctions are a slow process in which bidders incur incremental transaction costs if they delay bidding this paper presents models of slow dutch auctions that include these costs and explain this belief we first present a decision theoretic model of a slow dutch auction while simple the decision theoretic model is fairly general and provides the basic intuition underlying our revenue results we then develop a game theoretic model of a slow dutch auction we derive two symmetric payoff equivalent equilibria of the game in the absence of a cost of return and then consider the more general case of costly return when the cost of return is in an appropriate range the seller s expected revenue is an increasing function of that cost

familiarity breeds investment diaspora networks and international investment what explains cross national patterns of international portfolio and foreign direct investment fdi while existing explanations focus on the credibility of a policy maker s commitment we emphasize the role of diaspora networks we hypothesize that diaspora networks connections between migrants residing in investing countries and their home country influence global investment by reducing transaction and information costs this hypothesis is tested using dyadic cross sectional data for both portfolio and fdi the findings indicate that even after controlling for a multitude of factors disapora networks have both a substantively significant effect and a statistically significant effect on cross border investment

the divergent effects of joining international organizations trade gains and the rigors of wto accession governments have joined the world trade organization wto in vastly different ways some have taken mere days to join without undertaking any trade liberalization while others have taken more than a decade and been forced to undergo significant liberalization we argue that the more rigorous a state s accession to an international organization io and thus the greater policy change required to join the greater the benefits it will receive from membership in the organization in the trade context states facing greater scrutiny from the wto and thus engaging in greater trade liberalization as part of the wto accession process should experience greater trade on joining compared to those who face little scrutiny and engage in little if any liberalization we develop a three part classification of wto members based on type of accession early automatic and rigorous and then compile detailed original data on the accession experiences of each relevant state including length of time number of veto players rounds of questions and tariff and nontariff commitments results of exhaustive quantitative tests on all countries from 1950 to 2006 which are robust to estimator sample period and model specification choices consistently demonstrate that those who engage in the greatest amount of accession driven liberalization experience the greatest trade increases from wto membership particularly in the years right after joining in contrast those who do little or nothing to join do not see any trade gains from being a wto member these findings reconcile previous findings on the effects of wto membership on trade highlight the causal importance of io accession and illuminate the conditions under which ios will have beneficial effects for member states

why the long term auto correlation has not been eliminated by arbitragers evidences from nymex abstract the efficient market hypothesis claims that market prices follow the random walk and that any predictable trend will be eliminated by arbitragers in a short period of time however the fractal market hypothesis disagrees asserting that long term memory can persist in the market to understand why this conflict exists we propose a method to explore the long term market trend using the local hurst exponent and seek to obtain the extra yield performance is evaluated by using both a simulation and the high frequency 5 min data and the daily data the result indicates that the model performs well with the uni fractal series in the simulation however the model shows limited predictive abilities with the data from the real market due to the multi fractal characteristics although the long term trends persist in the markets and can be identified with statistical significance traders cannot beat the market because of the time varying feature and because the strength of long term memory is not strong enough to cover the transaction costs the result reconciles the long term auto correlations with emh in a quantitative manner

design of discrete dutch auctions with consideration of time abstract as a departure from much of the existing literature that aims at maximizing the expected revenue from a single auction this research work is concerned with the design of discrete dutch auctions to achieve the optimal balance between the selling price of the object and the auction duration so that the auctioneer s expected revenue per unit of time is as high as possible the new objective is especially important in trading perishable products or services when multiple auctions are to be conducted by the auctioneer for different sellers during a limited period of time our findings indicate that the proposed discrete dutch auction models generate higher average revenues per unit of time for the auctioneer than their counterparts without consideration of time this is achieved by reducing the duration of each auction in exchange for more auctions to be held within the given time frame so that the small decrease in the revenues from the longer auctions is more than compensated for by the large increase in the total revenues from the shorter auctions the numerical results show that the proposed discrete dutch auction design becomes extremely useful when the number of bidders becomes large it is also shown that complete knowledge about the number of bidders in the auction results in a higher auctioneer s expected revenue per unit of time

technical analysis and the spanish stock exchange testing the rsi macd momentum and stochastic rules using spanish market companies the aim of this research is to examine the result of the application of the indicators relative strength index rsi moving average convergence divergence macd momentum and stochastic in different companies of the spanish continuous market by using these indicators it is intended to give purchase and sale recommendations to small investors the generation of great capital gains depends on the type of the stock exchange company and the indicator which is being used in addition this research solves the problems in case of ambiguity in the indicators for the traders

multilateral determinants of regionalism the effects of gatt wto on the formation of preferential trading arrangements preferential trading arrangements ptas have spread widely over the past fifty years during the same era multilateral openness has grown to unprecedented heights spurred by the general agreement on tariffs and trade gatt and its successor the world trade organization wto if the cornerstone of the manifestly successful multilateral regime is nondiscrimination why have its members increasingly resorted to preferential liberalization we argue that developments at the heart of gatt wto encourage its members to form ptas as devices to obtain bargaining leverage within the multilateral regime specifically the growth in gatt wto membership the periodic multilateral trade negotiation rounds as well as participation and especially losses in formal gatt wto disputes have led its members to seek entrance into ptas conducting the first statistical tests on the subject we find strong evidence in support of this argument

naive trading rules in financial markets and wiener kolmogorov prediction theory a study of technical analysis this article attempts a formal study of technical analysis which is a class of informal prediction rules often preferred to wiener kolmogorov prediction theory by participants of financial markets yet wiener kolmogorov prediction theory provides optimal linear forecasts this article investigates two issues that may explain this contradiction first the article attempts to devise formal algorithms to represent various forms of technical analysis in order to see if these rules are well defined second the article discusses under which conditions if any technical analysis might capture those properties of stock prices left unexploited by linear models of wiener kolmogorov theory copyright 1991 by university of chicago press
