standardization and variety abstract in the tradeoff between standardization and variety there can be too much or too little variety the latter possibility can only happen if there are several equilibria

the economics of investor protection isds versus national treatment abstract investor state dispute settlements isds are supposed to protect foreign investors against domestic policies causing unjustified harm this paper scrutinizes the effects of isds and national treatment provisions in a two period model where foreign investment is subject to a hold up problem it shows that isds may increase welfare but comes with additional regulatory distortions in the first period a national treatment provision avoids these regulatory distortions but implies entry distortions because it makes the hold up problem also apply to domestic firms if the domestic regulatory framework applies to many domestic firms a national treatment provision welfare dominates isds

the role of multilateral institutions in international trade cooperation the world trade organization wfo lacks the power to directly enforce agreements it is therefore important to understand what role the wto can play to facilitate international cooperation and whether a multilateral institution can offer distinct advantages over a web of bilateral agreements this paper examines two potential benefits of a multilateral trade institution first verifying violations of the agreements and informing third parties thus facilitating multilateral reputation mechanisms second promoting multilateral trade negotiations rather than a web of bilateral negotiations the model suggests that a multilateral approach is particularly important when there are strong imbalances in bilateral trading relationships

dynamic processes for public goods an institution oriented survey a nontechnical but nevertheless not informal account is given of dynamic models recently developed in the theory of public goods after a purely descriptive presentation of three basic models section 2 and their many subsequent extensions section 3 various reflections are made in section 4 on issues raised by an institutional perspective first the usual planning interpretation of such processes is presented and commented upon next contrasting normative and positive approaches to public goods it is argued that one category of processes can be given an interpretation much in line with the literature on positive public economics third the planning vs voluntary exchange institutions are contrasted from the point of view of cooperation among the agents in an economy with public goods

optimal capital income taxation with incomplete markets borrowing constraints and constant discounting for a wide class of infinitely lived agent models chamley has shown that the optimal capital income tax rate is zero in the long run lucas has argued that for the u s economy there is a significant welfare gain from switching to this policy this paper shows that for the bewley class of models with incomplete insurance markets and borrowing constraints the optimal tax rate on capital income is positive even in the long run therefore cutting the capital income tax to zero may well lead to welfare losses

consumer demand and the life cycle allocation of household expenditures the purpose of this paper is to estimate the parameters of household preferences that determine the allocation of goods within the period and over the life cycle using micro data in doing so the authors are able to identify important effects of demographics labor market status and other household characteristics on the intertemporal allocation of expenditure they test the validity of the life cycle model using excess sensitivity tests and find that controlling for demographics and labor market status variables can largely explain the excess sensitivity of consumption to anticipated changes in income

precautionary wealth accumulation evidence from canadian microdata this paper estimates the effect of labour income uncertainty on wealth accumulation using two data sources wealth information is obtained from the master files of the new canadian survey of financial security 1999 sfs labour income risk proxies are constucted by industry using the canadian survey of labour and income dynamics slid between 1996 and 2001 the empirical results suggest the presence of a strong precautionary saving motive among canadian households for broad definitions of wealth furthermore consistent with the buffer stock saving model the level of precautionary funds significantly increases when households face liquidity constraints ce texte calcule l effet de l incertitude du revenu de travail sur l accumulation de la richesse a l aide de deux sources de donnees les donnees sur la richesse sont tirees des resultats de l enquete sur la securite financiere esf de 1999 les coefficients de risque attaches aux diverses industries sont developpes a partir des resultats de l enquete sur la dynamique du travail et du revenu edtr entre 1996 et 2001 les resultats empiriques suggerent la presence d une forte motivation des menages canadiens aepargner aux fins de precaution si l on accepte des definitions assez comprehensives de la richesse de plus d une maniere qui correspond au modele d epargne pour stockage tampon le niveau des fonds aux fins de precaution s accroit de maniere significative a proportion que les menages font face a des contraintes de liquidite

endogenous structures of association in oligopolies the formulation of associations of firms in an oligopoly with linear demand is analyzed as a two stage noncooperative game in the first stage firms form associations in order to decrease their costs and in the second stage they compete on the market examples of associations include r d joint ventures and groups of firms adopting common standards in equilibrium the associations formed exhibit two general features they are asymmetric and inefficient

exchange rates and unfair trade an examination of the changing country pattern of dumping and subsidy complaints by u s companies over time suggests that exchange rate fluctuations are a significant factor in determining case filings especially against japanese companies the inverse relationship observed between filings and the real external value of the u s dollar is consistent both with the traditional or technical interpretation of dumping and subsidy cases and with the view that they are promoted by rent seeking activities of lawyers and economists representing petitioners while this result says nothing about the merits of any particular case it cautions that the prevalence of unfair trade is not exogenous with respect to broader macroeconomic considerations copyright 1989 by mit press

survey measures of risk aversion and prudence this paper utilizes a thought experiment conducted by the bank of italy to estimate absolute and relative risk aversion along with absolute and relative prudence for a broad cross section of italian households upper and lower bounds are calculated for each parameter and comparisons are made across socio demographic groups evidence is found of decreasing absolute risk aversion decreasing absolute prudence increasing relative risk aversion and increasing relative prudence

installed base and compatibility innovation product preannouncements and predation a good is often more valuable to any user the more others use compatible goods the authors show that this effect may inhibit innovation if an installed base exists and transition to a new standard must be gradual early adopters bear a disproportionate share of transient incompatibility costs this can produce excess inertia the installed base however is stranded if the new standard is adopted this may create excess momentum these dynamic effects have strategic implications temporary price cutting can permanently prevent entry and product preannouncements can be critical in innovation these strategic actions have ambiguous welfare effects

large investors regulatory taking and investor state dispute settlement abstract this paper offers an economic analysis of an international investor state dispute settlement regime isds in markets with large investors it identifies a reason for strategic overinvestment by the domestic industry leading to permissive regulation in the absence of isds an ideal investor state dispute settlement arrangement efficiency oriented transaction cost free with untouchable fully reliable and unbiased judges has positive and negative effects in this framework it generates an equal level playing field for domestic and foreign investors but it magnifies an existing overinvestment problem and may reduce world welfare the results explain anecdotal evidence according to which isds that protects foreign investors is liked by the domestic industry and disliked by other interest groups in the host country

a quantile based test of protection for sale model this paper proposes a new test of the protection for sale pfs model by grossman and helpman 1994 unlike existing methods in the literature our approach does not require any data on political organization we use quantile and quantile iv regressions to do so using the data from gawande and bandyopadhyay 2000 surprisingly the results do not provide any evidence favoring the pfs model we also explain why previous work may have inadvertently found support for it

self enforcing trade agreements evidence from time varying trade policy the bagwell and staiger 1990 theory of cooperative trade agreements predicts new tariffs i increase with imports ii increase with the inverse of the sum of the import demand and export supply elasticities and iii decrease with the variance of imports the authors find us import policy during 1997 2006 to be consistent with this theory a one standard deviation increase in import growth the inverse of the sum of the import demand and export supply elasticity and the standard deviation of import growth changes the probability that the us imposes an antidumping tariff by 35 percent by 88 percent and by 76 percent respectively

non price strategic behavior the case of bank branches abstract we perform an empirical study of banks branching decisions as a strategic non price variable in an oligopolistic setting using panel data of banks from norway we find clear evidence that banks act strategically in their branching decisions taking into consideration the future response from rival banks the analysis is applied to a unique data set which covers the entire banking sector during both pre and post banking crisis periods where very different types of conduct are found in each of these periods both for banks and borrowers moreover we find that a bank specific branch network does not confer externality on other banks as a result branch network affects only market shares but not market size

is the wto passe the wto has delivered policy outcomes that are very different from those likely to emerge out of the recent wave of preferential trade agreements ptas should economists see this as an efficient institutional hand off where the wto has carried trade liberalization as far as it can manage and is now passing the baton to ptas to finish the job this paper surveys a growing economics literature on international trade agreements and argues on this basis that the wto is not passe rather and subject to some caveats this survey of research to date suggests that the wto warrants strong support while a more cautious view of ptas seems appropriate

investments in human capital wage uncertainty and public policy abstract the importance of risk characteristics of human capital for the design of tax and education policy is explored wages are uncertain and education while increasing the expected wage may increase or decrease wage variance the government has strong reasons to encourage human capital formation in the latter case partly due to the insurance effect of human capital and partly due to the way the individuals under a plausible restriction on prudence respond to changes in risk the analysis is illustrated using two models of education one where education helps the individuals make better occupational choices and a standard risk augmented becker type model

shared atm networks and banking competition abstract in this paper we study the incentives of banks to share their automatic teller machines atms when they are competitors in the market for deposits we construct a stylized model of banking competition which emphasises the distinctive features of atm compatibility we find that in equilibrium either a strict subset of banks share their atms or total incompatibility prevails we also derive the implications for atm compatibility of withdrawal fees interchange bank fees entry and depositor switching costs finally we investigate the normative implications of our model and draw some policy conclusions

uncertainty and the neutrality of government financing policy abstract some ideas from the theory of finance are applied to consider whether debt financed tax cuts affect desired consumption it is shown that government financing policy is a matter of indifference to infinitely lived households if a perfect substitute for public debt exists the analysis allows for uncertainty about future taxes and for missing markets in some kinds of assets income redistribution risk and the public insurance aspects of an income tax scheme qualify this neutrality result but in general the net effect is ambiguous the real resource costs of financial transacting as well as government superiority in the intermediation process may be one rationale for activist debt management policy a better understanding of functioning capital markets is essential to evaluate these arguments

the determinants of technology adoption the case of the banking firm using data on the adoption of automatic teller machines by firms in the banking industry this study examines the relationship between the decision to adopt new technology and its determinants since banking firms differ considerably in terms of the competitive environments in which they operate focusing on this one innovation in this industry allows a stronger test of the relationship between market structure and the adoption of new technology than has been previously conducted using a failure time estimation procedure we find that larger banks and banks operating in more concentrated local banking markets register a higher conditional probability of adopting this new technology all else equal we also find that other results are consistent with the underlying model and that the bank s regulatory environment shapes its adoption decision in plausible ways

precautionary saving motives an assessment from uk time series of cross sections this paper gauges the strength of precautionary saving motives by estimating the coefficient of prudence from the u k family expenditure survey data set a time series of cross sections the instrumental variables estimates reveal that greater uncertainty systematically leads to larger current savings most of these impacts are large enough to be statistically consistent with widely accepted beliefs about attitudes towards risk so that precautionary saving behavior cannot be refuted moreover the households which are less likely to face liquidity constraints or to share risks are more sensitive to uncertainty finally the households for which the head works in the manufacturing industry are more inclined to self insure against uncertainty copyright 1996 by royal economic society

did the financial crisis in japan affect household welfare seriously we investigate whether and how the credit crunch during the financial crisis in japan affected household welfare we estimate the consumption euler equation with endogenous credit constraints using household panel data for 1993i 1999 generating several findings first a small but non negligible portion of the households faced credit constraints during the crisis rejecting the standard consumption euler equation second the credit crunch affected household welfare negatively albeit not seriously the estimated welfare loss ranges between two to ten percent increases in marginal utility depending on income level finally our results corroborate that the credit crunch in japan was supply driven

macroeconomic factors and antidumping filings evidence from four countries abstract this paper examines the relationship between antidumping filings and macroeconomic factors real exchange rate fluctuations affect the two criteria for dumping in opposite ways making the overall effect on filings ambiguous in theory examining the filing patterns of the four major users of ad law during the 1980 98 period we find that real exchange rates and domestic real gdp growth both have statistically significant impacts on filings bilateral filing data indicate that a one standard deviation real appreciation of the domestic currency increases filings by 33 we also find one standard deviation fall in domestic real gdp increases filings by 23

precautionary saving under liquidity constraints evidence from rural pakistan this paper investigates precautionary saving under liquidity constraints in pakistan using household panel data in particular while we estimates kimball s 1990 prudence parameter we deviate from dynan s 1993 framework by explicitly considering liquidity constraints as in zeldes 1989 by doing so we attempt to differentiate the standard precautionary saving caused by uncertainty from the one due to liquidity constraints furthermore endogenous liquidity constraints are considered to resolve issues of selection biases in this study we document substantial evidence of the presence of precautionary saving in pakistan more specifically the estimated prudence is significantly higher for liquidity constrained households as compared with unconstrained ones the results support the emerging view that facilitating saving may often be more important than finding better ways of lending to the poor

investment and usage of new technologies evidence from a shared atm network when new technologies become available it is not only essential that firms have the correct investment incentives but often also that consumers make the proper usage decisions this paper studies investment and usage in a shared atm network be cause all banks coordinate their atm investment decisions there is no strategic but only a pure cost saving incentive to invest at the same time because retail fees for cash withdrawals are regulated to zero at both branches and atms consumers may not have the proper incentives to substitute their transactions from branches to the available atms we develop an empirical model of coordinated investment and cash withdrawal demand where banks choose the number of atms and consumers decide whether to withdraw cash at atms or branches we find that banks substantially underinvested in the shared atm network and thus provided too little geographic coverage this contrasts with earlier findings of strategic overinvestment in networks with partial incompatibility furthermore we find that consumer usage of the avail able atm network is too low because of the zero retail fees for cash withdrawals at branches a direct promotion of investment through subsidies or other means can improve welfare but the introduction of retail fees on cash withdrawals at branches would be more effective even if this does not encourage investment per se

a model of expertise we study a model in which perfectly informed experts offer advice to a decision maker whose actions affect the welfare of all experts are biased and thus may wish to pull the decision maker in different directions and to different degrees when the decision maker consults only a single expert the expert withholds substantial information from the decision maker we ask whether this situation is improved by having the decision maker sequentially consult two experts we first show that there is no perfect bayesian equilibrium in which full revelation occurs when both experts are biased in the same direction it is never beneficial to consult both in contrast when experts are biased in opposite directions it is always beneficial to consult both indeed in this case full revelation may be induced in an extended debate by introducing the possibility of rebuttal

network effects on cash card substitution in transactions and low interest rate regimes we develop a nash game on the adoption of a new eftpos electronic fund transfer at point of sale card payment media given cash is dispensed by a competitive atm automated teller machine network equilibrium conditions when cash and card use coexist entail a specific relationship between the card network coverage parameter super k and the proportion of cash financed expenditures we derive a payments innovation technology constrained transactions demand for money which is highly interest rate sensitive in low interest rate regimes data on cash card use in the uk 1990 97 is used to calibrate the model

a theory of managed trade this paper proposes a theory that predicts low levels of protection during periods of normal trade volume coupled with episodes of special protection when trade volumes surge this dynamic pattern of protection emerges from a model in which countries choose levels of protection in a repeated game facing volatile trade swings high trade volume leads to a greater incentive to defect unilaterally from cooperative tariff levels therefore as the volume of trade expands the level of protection must rise in a cooperative equilibrium to mitigate the rising trade volume and hold the incentive to defect in check copyright 1990 by american economic association

the degree of precautionary saving a reexamination abstract extending dynan s methodology dynan k 1993 how prudent are consumers journal of political economy 101 1104 1113 we show that a significant fraction of the prudence parameter puzzle can be explained by a downward omitted variable bias further the estimated prudence is substantially higher for liquidity constrained households

import protection business cycles and exchange rates evidence from the great recession this research estimates the impact of macroeconomic fluctuations on import protection policies over 1988 q1 2010 q4 for five industrialized economies the united states european union australia canada and south korea there is evidence of a strong countercyclical trade policy response in the pre great recession period of 1988 q1 2008 q3 during which increases in domestic unemployment rates real appreciations in bilateral exchange rates and declines in the gdp growth rates of bilateral trading partners led to substantial increases in new temporary trade barriers it then applies this pre great recession empirical model to realized macroeconomic data from 2008 q4 2010 q4 and find it predicts a surge of new import protection during the great recession e g for the us and eu the model predicts new trade barriers would cover an additional 15 percentage points of nonoil imports well above the baseline level of 2 3 percent of import coverage immediately preceding the crisis finally the research examines why the realized trade policy response differed from model predictions while exchange rate movements played an important role in limiting new import protection during the great recession there is also evidence of one particularly important change in trade policy responsiveness i e in this period governments refrained from imposing new temporary trade barriers against foreign trading partners experiencing their own weak or negative economic growth

trade policy flexibilities and turkey tariffs antidumping safeguards and wto dispute settlement trade policy commitments to lower import tariffs and to maintain tariffs at low levels entail short and long run political economic costs and benefits empirical work examining the relationship between such commitments and the exercise of trade policy flexibilities is still relatively nascent especially for emerging economies this paper provides a rich empirically based assessment of ways that turkey exercised trade policy flexibilities during the global economic crisis of 2008 11 first and despite multilateral and customs union commitments that might limit changes to applied tariffs turkey made changes to both its applied most favored nation and preferential tariffs that cumulatively affect nearly 9 percent of manufacturing imports and 10 percent of import product lines second turkey s cumulative application of temporary trade barrier ttb policies antidumping safeguards and countervailing duties are estimated to impact by 2011 an additional 4 percent of imports and 6 percent of product lines other surprising results on turkey s use of flexibilities include extending the duration of previously imposed antidumping and safeguards beyond expected removal dates removing one ttb policy over a set of products and immediately reapplying a different ttb policy covering lengthy upstream and downstream segments of important industries and deepening discriminatory preference margins already inherent in existing preferential trade agreements

competition and integration among complements and network market structure this article analyzes the competition and integration among complementary products that can be combined to create composite goods or systems the model generalizes the cournot duopoly complements model to the case in which there are multiple brands of compatible components it analyzes equilibrium prices for a variety of organizational and market structures that differ in their degree of competition and integration the model applies to a variety of product networks including automatic teller machines real estate multiple listing services and airlines crs as well as to nonnetwork markets of compatible components such as computer cpus and peripherals hardware and software and long distance and local telephone services copyright 1992 by blackwell publishing ltd

a framework for analyzing efficiency risks costs and innovations in the payments system the market for payment instruments such as cash checks and electronic funds transfers is one of the largest most important and economically interesting markets in the economic system virtually every economic transaction requires the use of a payment instrument therefore on a value basis the demand for payment instruments equals the demand for all other goods services assets and other financial instruments traded in the economy combined in a monetary economy the buyers and sellers of any commodity must not only agree on the price and quantity to be exchanged but must also concur on the payment method that will be employed in the exchange that is every commodity buyer takes on the role of a payor and every commodity seller takes on the role of a payee and they jointly demand a payment instrument of equal value to the commodities exchanged the size of payments markets is illustrated in table 1 which shows transactions

the evolution of common law we present a model of lawmaking by appellate courts in which judges influenced by policy preferences can distinguish precedents at some cost we find a cost and a benefit of diversity of judicial views policy motivated judges distort the law away from efficiency but diversity of judicial views also fosters legal evolution and increases the law s precision we call our central finding the cardozo theorem even when judges are motivated by personal agendas legal evolution is on average beneficial because it washes out judicial biases and renders the law more precise our paper provides a theoretical foundation for the evolutionary adaptability of common law

wto tariff commitments and temporary protection complements or substitutes abstract there is a long held notion in the trade policy literature that traditional tariff instruments and temporary protection tp measures are substitutes despite this prediction there is only mixed empirical evidence for a link between tariff reductions and the usage pattern of antidumping safeguard and countervailing duties based on recent theoretical advances i argue in this paper that the relevant trade policy margin for implementing tp measures is instead tariff overhangs the difference between wto bound and applied tariffs lower tariff overhangs constrain countries to raise their mfn applied rates without legal repercussions independent of past tariff changes using detailed sectoral data for a sample of 30 wto member countries during the period 1996 2014 i find strong evidence for an inverse link between tariff overhangs and tp activity this result implies that tariff overhangs and tp measures are substitutes vindicating the importance of existing tariff commitments as a key determinant of alternative protection instruments

to surcharge or not to surcharge an empirical investigation of atm pricing this paper investigates depository institutions decisions whether or not to impose surcharges direct usage fees on nondepositors who use their atms in addition to documenting patterns of surcharging we examine motives for surcharging including both direct generation of fee revenue and the potential to attract deposit customers who wish to avoid incurring surcharges at an institution s atms consistent with expectations we find that the probability of surcharging increases with both the institution s share of market atms and the time since surcharging was first allowed in the state and decreases with increasing local atm density further we find evidence consistent with the use of surcharges to attract deposit customers who are new to the local banking market but we find no evidence that larger banks use surcharges as a means to attract existing customers away from smaller local competitors

a computation of interest equivalences for nonprice characteristics of bank products this paper seeks to price the nonprice features of british retail bank products it outlines a methodology for computing interest equivalences for a selection of characteristics estimates are obtained for a full observation set and a subset of survivor products on an efficiency frontier its main findings are that certain nonprice features are significant and there does not appear to be a strong case for separating out those products that lie on an efficiency frontier copyright 1992 by ohio state university press

a gmm test of the precautionary saving hypothesis with nonexpected utility preferences using gmm estimation with the us data from january 1967 to april 2003 the precautionary saving hypothesis is tested using time varying consumption uncertainty and a nonexpected utility model of intertemporal optimal consumption overidentifying restrictions of the model specification are also tested for both expected and nonexpected utility using hansen s j statistics it was found that the precautionary saving hypothesis did not hold under expected utility preferences but did hold partly under nonexpected utility preferences

the effects of shared atm networks on the efficiency of turkish banks this study investigates whether forming shared atm networks has yielded positive benefits for banks in turkey by increasing their productive efficiency using a data envelopment analysis dea approach pure technical and scale efficiency scores of turkish banks are estimated and analysed for the period 2000 2003 the results suggest that although it is possible to realize positive effects through atm sharing arrangements there are multiple factors that determine which banks realize such benefits the geographical distribution of shared atms between urban and rural markets and the level of competition between banks within urban areas are shown to be important determinants of differences in bank efficiency this discrepancy between the gains associated with atm sharing may have important implications concerning the adoption and sharing of new technology by banks in developing countries

the political economy of administered protection trade restrictions are hardly ever voted directly by congress though the threat of direct congressional action is frequently present pressure for protection is usually applied through the major instruments for the administrative regulation of imports the antidumping and countervailing duty procedures and the escape clause mechanism in this paper we will examine these instruments for the administrative regulation of imports the form of the paper is not novel a theory of how these mechanisms work is developed then operational implications of this theory are deduced and tested over the record of countervailing duty antidumping and escape clause cases decided from 1975 through 1979 this is the period over which the trade act of 1974 was in force because the nature of these mechanisms is relatively unfamiliar a relatively large amount of institutional information is provided

the role of dispute settlement procedures in international trade agreements although disputes are typically treated as synonymous with concerns about enforcement in economic models of trade agreements in reality most wto disputes seem to concern the interpretation of vague provisions or instances where the agreement is silent and some have suggested that the wto s dispute settlement body dsb could usefully grant exceptions to rigid contractual obligations these activist dsb roles could help complete an incomplete contract but how activist should the dsb be should dsb rulings set precedent we address these questions by characterizing the optimal choice of contract form and dsb mandate under various contracting conditions jel codes d02 d78 d86 f13 k12 k33

impacts of trade and the environment on clustered multilateral environmental agreements many countries align their environmental policy and environmental regulation by way of multilateral environmental agreements meas previous work in economics provided insights in the economic and political determinants of meas at large this paper distinguishes meas by the main issues covered and classifies them in five clusters biodiversity atmosphere land chemicals and hazardous wastes and seas then the role of environmental economic and political factors and of dynamic and cross cluster effects is studied at the level of mea clusters two findings stand out from this empirical analysis first economic size and multilateral trade liberalisation of countries are found to be the most important drivers of mea participation across all clusters second adjustment costs turn out to deter and in particular cross cluster spillovers turn out to stimulate mea participation across countries and clusters

concorrencia e performance do setor bancario em um mercado heterogeneo financial markets have become increasingly integrated throughout the world does this mean that local financial institutions are becoming irrelevant we argue that due to the information symmetries involved in credit concession and banks role as monitors the answer is no motivated by empirical evidences that show a great dispersion among brazilian banks interest spreads we have developed an imperfect competition model where the need to monitor loans and the heterogeneity of demand for credit create market niches in which it is possible to systematically charge higher interest rates on credit bank deposits do not need monitoring thus the tendency to more intense competition the difference in the level of competition under which these two services operate can generate an inefficient allocation of resources in the economy particularly harming less developed areas volumes of loans and deposits observed in different brazilian cities and states support the conclusions of the model

branching scale economies and banking costs abstract in this paper we develop and estimate a model of bank costs based on a theory of the branch cost function first we show that convenient branch location is important to banking customers and implies that banks do not necessarily operate branches at minimum average cost this theoretical result provides a rationale for including branch variables in the bank cost function second we estimate a statistical cost equation derived explicitly from assumptions about the branch cost function and including branch output variables our empirical results suggest substantial economies of scale at the branch level but no economies from expansion by branching finally we show that the resulting cost structure of the banking industry does not imply that a highly concentrated banking structure is necessary for efficiency thus economies of scale would not be expected to force small banks out of the market even if current restrictions on interstate banking are liberalized

cooperation among competitors some economics of payment card associations we analyze platforms in two sided markets with network externalities using the specific context of a payment card association we study the cooperative determination of the interchange fee by member banks the interchange fee is the access charge paid by the merchants banks the acquirers to cardholders banks the issuers we develop a framework in which banks and merchants may have market power and consumers and merchants decide rationally on whether to buy or accept a payment card after drawing the welfare implications of a cooperative determination of the interchange fee we describe in detail the factors affecting merchant resistance compare cooperative and for profit business models and make a first cut in the analysis of system competition

on the interaction between vertical and horizontal product differentiation an application to banking the author studies the conditions under which banks offer remote access note there exists interaction between location and taste for remote access offering remote access is an instrument to partially segment depositors according to their taste for that technology the interaction between location and taste for remote access enhances this effect different equilibria emerge as the result of two effects first introducing remote access steals depositors from the opponent as the product specification becomes more appealing second deposit rate competition is affected as remote access determines the substitutability of banks copyright 1996 by blackwell publishing ltd

how does future income affect current consumption this paper tests a straightforward implication of the basic life cycle model of consumption that current consumption depends on expected lifetime income the paper projects future income for a panel of households and finds that consumption is closely related to projected current income but unrelated to predictable changes in income however future income uncertainty has an important effect consumers facing greater income uncertainty consume less the results are consistent with buffer stock models of consumption like those of deaton 1991 or carroll 1992a 1992b where precautionary motives greatly reduce the willingness of prudent consumers to consume out of uncertain future income

preferential trade agreements and antidumping protection abstract are preferential trade agreements ptas stumbling blocks or building blocks towards multilateral trade liberalization we address this question by investigating the effects of the negotiation and implementation of ptas on the use of antidumping ad i e the most common form of contingent trade protection by member countries against non members as there has been a concurrent surge in regionalism and ad activity since the 1990s theoretically derived empirical predictions are supported by the empirical analysis based on the 15 most intense users of ad the results demonstrate that both the negotiation and the implementation of ptas lead to fewer ad measures against non member countries except for members of customs union agreements in force facing large import surges from non members thus our results highlight a building block effect of ptas on multilateral trade cooperation when it comes to ad protection

tariff binding and overhang theory and evidence abstract most market access commitments under the wto are in the form of bindings on applied tariff rates we observe two important regularities in the data first applied tariffs are often lower than the bound tariffs providing governments with substantial policy flexibility second the extent of flexibility varies substantially across sectors and countries in a sharp contrast to the prediction of standard trade agreement models we observe a strong negative correlation between tariff commitments and measures of import market power we model the trade off between discipline and flexibility in the design of trade agreements and argue that recognizing this trade off is the key to explain the observed patterns in the tariff binding commitments and applied tariffs under the wto

in or out standards discretion compliance and the wto self enforcement in international agreements in the presence of uncertainty in the form of shocks and imperfect information regarding the extent of compliance by other members is enhanced by the use of standards in performance of commitments standards are less precise than rules they must be sufficiently demanding that undercompliance is distinguishable from non compliance discretion permits undercompliance as an alternative to renegotiation of commitments safeguards and the filing of disputes undercompliance particularly when restrained is a lower cost and less confrontational resolution to addressing adverse shocks signatories are restrained in undercomplying so that the effects of their actions are imperfectly distinguishable from the effects of shocks compliance and evidentiary standards for formal disputes define the accomplishments of the agreement evidentiary standards serve as an important discipline to undercompliance even in the absence of formal disputes

atm surcharges effects on deployment and welfare this paper analyzes the effects of atm surcharges on deployment and welfare in a model where banks compete for atm and banking services foreign fees surcharges and the interchange fee are endogenously determined we find situations in which surcharges are welfare enhancing under strategic fee setting the increase in deployment caused by surcharging might compensate the surplus loss caused by the increase in prices

economic history and economics i have in the back of my mind a picture of the sort of discipline economics ought to be or at least the sort of discipline i wish it were if economics were practiced in that way there would be nothing problematical about its reciprocal relationship with economic history it would be pretty clear what it is that economic theory offers to economic history and what economic history offers to economic theory i will try to describe what i mean below for better or worse however economics has gone down a different path not the one i have in mind one consequence not the most important one but the one that matters for this discussion is that economic theory learns nothing from economic history and economic history is as much corrupted as enriched by economic theory i will come to that too later on you will notice that i am using strong language i am prepared to admit right away that i may be dead wrong in my judgements but there is no point in pussyfooting bluntness may lead to an interesting discussion after all no one would remember the old german historical school if it were not for the famous methodenstreit actually no one remembers them anyway there must be a lesson in that to get right down to it i suspect that the attempt to construct economics as an axiomatically based hard science is doomed to fail there are many partially overlapping reasons for believing this but since that is not the topic under discussion today i do not have to lay them out in an orderly way i hope the following hodgepodge will convey what i mean a modern economy is a very complicated system since we cannot conduct controlled experiments on its smaller parts or even observe them in isolation the classical hardscience devices for discriminating between competing hypotheses are closed to us the main alternative device is the statistical analysis of historical time series but then another difficulty arises the competing hypotheses are themselves complex and subtle we know before we start that all of them or at least many of them are capable of fitting the data in a gross sort of way then in order to make more refined distinctions we need long time series observed under stationary conditions unfortunately however economics is a social science it is subject to damon runyon s law that nothing between human beings is more than three to one to express the point more formally much of what we observe cannot be treated as the realization of a stationary stochastic process without straining credulity moreover all narrowly economic activity is embedded in a web of social institutions customs beliefs and attitudes concrete outcomes are indubitably affected by these background factors some of which change slowly and gradually others erratically as soon as time series get long enough to offer hope of discriminating among complex hypotheses the likelihood that they remain stationary dwindles away and the noise level gets correspondingly high under these circumstances a little cleverness and persistence can get you almost any result you want i think that is why so few econometricians have ever been forced by the facts to abandon a firmly held belief indeed some of fortune s favorites have been known to write scores of empirical articles without once feeling obliged to report a result that contradicts their prior prejudices if i am anywhere near right about this the interests of scientific economics would be better served by a more modest approach there is enough for us to do without pretending to a degree of completeness and department of economics massachusetts institute of technology cambridge ma 02139

europe 1992 issues and prospects for the financial markets financial markets vittorio grilli one potential effect of the integration of european financial markets concerns the geographical location of financial hot spots it is likely that liberalization will tend to promote countries with already large and well developed international financial markets attracting the residents of smaller countries these markets will become larger and more liquid and thus even more appealing it is very unlikely that other european countries could design policies apt to threaten london s supremacy as the main european financial centre while the article focuses on the market for bank deposits similar considerations apply to other financial markets it appears that a large part of cross country bank deposits are explained by country specific factors such as particular institutional arrangements in the areas of capital controls tax regulations and secrecy laws however the relative importance of these factors varies between inter bank deposits and non bank deposits taxation and banking secrecy matter for non bank deposits while the very size of the economy influences inter bank deposits finally imperfect competition and switching costs imply that more intense competition wilt be felt primarily in the market for large deposits small deposit contracts will probably be unaffected by liberalization at least in the short run

theoretical foundations of negotiations and cost sharing in transfrontier pollution problems the negotiations model is described by a dynamic process bearing on a multilateral externality that converges to an individually rational pareto optimum the process embodies a cost sharing rule for pollutant abatement in the countries involved derived from a sharing rule of the surplus that is also shown to have strategic stability in the game theoretic sense of an imputation in the core of some cooperative game associated with the negotiation process the connections are explored between this cost sharing rule and the free rider problem in public goods theory

consumption puzzles and precautionary savings abstract when marginal utility is convex agents accumulate savings as a precautionary measure against labor income eventualities this paper shows that precautionary savings can go a long way in making the excess growth excess smoothness and excess sensitivity features of consumption consistent with the stochastic processes of labor income observed in the u s at the microeconomic level

the independent submarkets model an application to the spanish retail banking market abstract the aim of this paper is to test the predictions of sutton s independent submarkets model with data on the spanish retail banking market the prediction of this model for aggregates of submarkets is that the form of equilibrium outcome must involve some minimal degree of size inequality however within each submarket when three conditions hold the only form of equilibrium outcome will be an extreme fragmented structure to test these predictions firstly i propose methods to identify independent submarkets then i analyze the degree of inequality in bank sizes for markets with different levels of aggregation submarkets regions and national market using concentration by towns data i find that in single submarket towns the degree of inequality of the size among banks is zero moreover multimarket towns with a significant degree of concentration are shown to be formed by a different number of independent submarkets where each bank owns one branch nonetheless when the regional and the national bank markets are considered the degree of inequality in bank sizes becomes high these results are consistent with the predictions of the theoretical model

optimal trade policy with trade imbalances abstract optimal trade and capital control policies are characterized under a dynamic model with endogenous trade imbalances in the absence of capital controls optimal trade protection is counter cyclical optimal use of capital controls however dampens the time variation of optimal trade taxes generally trade imbalances are not predictive of optimal policy however optimal trade policy and equilibrium trade imbalances move together when a country grows consistently faster or slower than the rest of the world quantifying the model for the u s economy shows that welfare gains from optimal policy are largely due to static terms of trade effects implying that gains from time varying tariffs or capital controls are small

suspiciously timed trade disputes abstract this paper shows that electoral incentives crucially affect the initiation of trade disputes focusing on wto disputes filed by the united states during the 1995 2014 period we find that u s presidents are more likely to initiate a dispute in the year preceding their re election moreover u s trade disputes are more likely to involve industries that are important in swing states to explain these regularities we develop a theoretical model in which re election motives can lead an incumbent politician to file trade disputes to appeal to voters motivated by reciprocity

taking stock of antidumping safeguards and countervailing duties 1990 2009 this article examines the evolving cross country use of antidumping safeguard and countervailing duty policies temporary trade barriers ttbs over the period 1990 2009 i construct two new measures of imported products subject to the combined use of these ttbs before applying these measures to new data drawn from the world bank s temporary trade barriers database i then establish a number of facts regarding trends in historical use to benchmark against policy activity during the global economic crisis of 2008 09 the 2008 09 economic shock mostly accentuates patterns and trends already visible in the precrisis data e g while the major users of such policies overall combined to increase the product lines subject to ttbs by 25 per cent during the crisis this was driven almost entirely by developing economies which increased their product coverage by 40 per cent perhaps surprisingly recession affected high income economies increased their stock of product coverage by only 5 per cent during the crisis a muted policy response consistent with earlier trends in which major developed economies like the united states and eu reduced the stock of imported products they subject to ttbs to 2007 levels that were only 50 per cent as high as their within period peak furthermore a previously unidentified feature of the data is that a much larger share of china s exported products to other developing economies is subject to foreign imposed antidumping than its exports to developed economies the evidence confirms this feature is shared by a number of other major developing economy exporters deepening concern that these discriminatory trade barriers are increasingly a south south phenomenon finally i also clarify emerging trends in countervailing duty anti subsidy use across countries

theory and practice of decentralized planning procedures the paper surveys the theory of decentralized planning procedures dealing with price guided quantity guided and mixed procedures informational and incentive properties of the various procedures are dealt with as is the problem of public goods the practice of planning in the u s s r hungary and india is also discussed copyright 1990 by blackwell publishers ltd

consumption beyond certainty equivalence this paper discusses the recent research on the consumption function that has attempted to relax the assumption of certainty equivalence while there remain many open questions both theoretical and empirical it is clear that the assumption of certainty equivalence can be misleading under more plausible specifications of preferences toward risk uncertainty lowers the level of consumption increases the expected rate of growth of consumption and increases the response of consumption to news about income moreover changes in the amount of uncertainty are a potentially important source of fluctuations in consumption this abstract was borrowed from another version of this item

precautionary saving an explanation for excess sensitivity of consumption the permanent income hypothesis under certainty equivalence yields a martingale consumption process empirically this hypothesis is rejected because consumption is excessively sensitive to anticipated income one approach to account for excess sensitivity is to relax certainty equivalence by using utility functions that induce precautionary saving this article analyzes a hyperbolic absolute risk aversion utility function empirically some reasonable parameterizations of this specification allow one to match the excess sensitivity associated with the data these parameterizations also permit one to account for the excess smoothness problem excess sensitivity and excess smoothness however do not reflect the same phenomenon

mixed pricing in oligopoly with consumer switching costs abstract in this paper we develop an alternative and more natural two period model of duopolistic competition with switching costs we find that overall competition is always less severe when consumers find switching suppliers expensive however the relationship between the strength of competition and the importance of switching costs is not monotonic interestingly competition between ex ante identical firms naturally results in firms having asymmetric market shares in equilibrium

trade disputes and settlement we develop a model of trade agreements with renegotiation and imperfectly verifiable information in equilibrium trade disputes can occur and can be resolved in a variety of ways governments may settle early or trigger a court ruling and in the latter case they may implement the ruling or reach a post ruling settlement the model yields predictions on how the dispute outcome depends on the contracting environment and how it correlates with the optimal contract form we find support for a key prediction of our model using data on the outcomes of actual trade disputes in the general agreement on tariffs and trade world trade organization

the failure of competition in the credit card market the bank credit card market containing 4 000 firms and lacking regulatory barriers casually appears to be a hospitable environment for the model of perfect competition nevertheless this article reports that credit card interest rates have been exceptionally sticky relative to the cost of funds moreover major credit card issuers have persistently earned from three to five times the ordinary rate of return in banking during the periods 1983 88 the failure of the competitive model appears to be partly attributable to consumers making credit card choices without taking account of the very high probability that they will pay interest on their outstanding balances copyright 1991 by american economic association

logistic infrastructure and the international location of fragmented production abstract casual evidence suggests that multinational companies increasingly look for places with adequate transport and logistic infrastructure to locate affiliates that participate in cross border production sharing yet there are no systematic empirical analyses examining how logistic infrastructure interacts with the location decisions made by multinationals most studies on the determinants of fdi address the issue of transportation logistics by examining the impact of distance on the relevant outcome but distance does not capture by itself the quality of the logistic systems in place we overcome this shortcoming in the literature by embedding indicators of infrastructure into an empirical framework that examines whether countries with adequate logistic systems attract more vertical fdi and particularly in industries that are more dependent on logistic services we find that logistic infrastructure positively impacts vertical fdi in addition to the impact typically found on distance a change from the first quartile to the third quartile of the distribution of logistic infrastructure is associated with an average increase in the number of vertically integrated subsidiaries equivalent to 29

the permanent income hypothesis and the real interest rate some evidence from panel data abstract a test of the permanent income hypothesis in panel data is formulated taking into account both the time series and cross section variation in the rate of return the over identifying restrictions of the theory rejected

international environmental problems a simple taxonomy of international environmental problems is developed based on economic considerations the unidirectional externalities are illustrated by the case of one upstream and one downstream country the main problem in this case is an informational one the analysis of regional reciprocal externalities is illustrated by the acid rains in europe it is shown that an efficient solution could be achieved by transferable export rights finally global external problems are discussed with reference to greenhouse effects and extinction of species copyright 1990 by oxford university press

banking regulation and competition with product differentiation abstract the main motivation for prudential regulation is to increase the solvency of the banking sector however it is usually understood that tighter regulation also leads to more concentration and higher spreads thus these prudential measures are seen as implying a trade off between solvency and competition in this paper we argue that this trade off does not necessarily exist we present a model in which tighter capital requirements lead banks to choose a lower degree of product differentiation potentially inducing more intense competition and lower spreads the model is motivated by the recent evolution of the argentine banking sector

pursuing economic growth in asia the environmental challenge this paper identifies and discusses the five main areas of environmental management public policy that pose serious challenges to asian governments the first is the emerging issue of siting environmentally unfriendly facilities that may be necessary for growth but with the social and environmental costs borne primarily by local host residents and neighbourhood municipalities more commonly known as the not in my backyard syndrome the second issue is the critical need for pricing of non market environmental goods third is the issue of waste generation the fourth challenge is that of transboundary pollution which has become increasingly important with regard to its effects on health and foreign relations lastly the paper discusses global warming and climate change discussions on cost benefit analysis and the more novel method of establishing damage schedules are also presented this is particularly relevant to fundamental differences between developed and less developed countries

international agreements economic sovereignty and exit abstract we develop a model in which realisations of an ex ante uncertain domestic policy environment can make it attractive to a sovereign nation to renege on an international agreement we show in a fairly general setting in which the likelihood of exit is affected by the degree of cooperation that the possibility of exit reduces the optimal degree of initial cooperation full cooperation will never be optimal and the optimal degree of cooperation will never be such as to squeeze out any possibility of exit however an increase in global uncertainty may imply an increase in cooperation when exit risks are already large to begin with

the role of economics in global management of whales re forming or re founding iwc abstract the global management of whale species identified as an economic mixed good is addressed by means of economic theory of bargaining and institution making i will analyse i why it is important to take into account explicitly both consumptive use and non use values within international conventions on global mixed goods ii the role and nature of institutions dealing with global issues iii the role of bargaining between conflicting interests as a focal feature of the institution making process and iv the role of economic thinking in international conventions co operative and non co operative solutions are discussed and instruments aimed at achieving co operative bargaining analysed the study has both positive and normative implications with insights on social welfare enhancing institutional reforms although the study is broad yet special focus is given to the international whaling commission iwc this paper concludes that we should make economic theory operational within the realm of global institutions on the basis of the bargaining model the conclusion is that iwc should necessarily be re founded or at least re formed changing the convention from whaling to a whale it is suggested that the possibility of introducing compensatory side payments into the bargaining arena in order to increase social welfare and enforceability with respect to a ban scenario be investigated ethical implications of monetary compensations are considered in parallel with economic efficiency the limits and potentialities of economics and economic instruments are also tested globally with respect to the whale and other environmental issues

precautionary saving in the small and in the large the theory of precautionary saving is shown to be isomorphic to the arrow pratt theory of risk aversion making possible the application of a large body of knowledge about risk aversion to precautionary saving and more generally to the theory of optimal choice under risk in particular a measure of the strength of the precautionary saving motive analogous to the arrow pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving and to give a new interpretation of the dreze modigliani substitution effect copyright 1990 by the econometric society

consumption over the life cycle and over the business cycle the main aim of this paper is to assess the validity of the life cycle model of consumption in particular we address an issue that has recently received much attention especially in the macroeconomic literature that of excess sensitivity of consumption growth to income growth we do this using a time series of cross sections and a novel and flexible parameterization of preferences the former allows us to address aggregation issues directly while with the latter we can allow both the discount factor and the elasticity of intertemporal substitution eis to be affected by various observable variables and lifetime wealth the main findings can be summarized as follows i the excess sensitivity of consumption growth to labor income disappears when we control for demographic variables this is true both at life cycle and business cycle frequencies ii estimation of a flexible specification of preferences indicates that the elasticity of intertemporal substitution is a function of several variables including the level of consumption the eis increases with the level of consumption as expected iii the variables that change the eis are also important in explaining why we observe excess sensitivity over the business cycle iv we are able to reconcile our results with those reported both in the macro and micro literature v in our specification the elasticity of intertemporal substitution is not very well determined this result however should be taken with care as we have not made an effort to construct a preferred specification which would probably include additional controls for labor supply behavior the evidence presented shows that the life cycle model cannot be easily dismissed indeed we believe that the model does a good job at representing consumption behavior both over the life cycle and over the business cycle
