long term competition in a dynamic game the cold fish war this article presents a model of credible voluntary collective agreements in a dynamic game these agreements are implicit in collections of history dependent threat strategies i consider the strategies in a game of resource exploitation credibility is represented by perfect equilibrium voluntarism requires at least that all behavior be supported by the threat of collapse of the agreement which would return the players to the memoryless equilibrium collective rationality requires that the agreement be robust to the possibility of mutually beneficial renegotiation i analyze the set of agreements meeting each of these restrictions

corporate income tax competition double taxation treaties and foreign direct investment abstract in the presence of international capital mobility foreign direct investment is influenced by corporate income tax rates and the rules of how taxes paid in the host country are treated at home in this paper the exemption credit and deduction methods are considered as tax rules tax competition is modeled as a non cooperative game with respect to both corporate tax rates and the form of double taxation relief the subgame perfect equilibrium is shown to be independent of the tax rules since capital is inefficiently allocated the feasibility and the content of a cooperative contract between governments are analyzed it is argued that only the credit method requires neither compensatory payments nor fully harmonized tax rates this is consistent with the observation that tax credits are very often adopted in double taxation treaties

asymmetric fdi and tax treaty bargaining theory and evidence abstract tax treaties are often viewed as a mechanism for eliminating tax competition however this approach ignores the need for bargaining over the treaty s terms this paper focuses on how bargaining can affect the withholding taxes set under the treaty in a simple framework we develop hypotheses about patterns in treaty tax rates a key determinant for these patterns is the relative size of bilateral foreign direct investment fdi activity in plausible situations more asymmetric countries will negotiate treaties with higher tax rates this theory is then tested using 1992 data from us and organization for economic cooperation and development oecd bilateral tax treaties overall the data supports the prediction that greater asymmetric fdi activity increases the negotiated tax rates

do big countries win tariff wars yes it is widely believed that tariffs invite retaliation and that the postretaliation equilibrium l eaves all countries worse off than they would be at free trade the a uthors present a simple pure exchange model with two countries and t wo goods and show which endowment patterns are consistent with this belief they find that if one country is substantially bigger than th e other it can expect to gain from a tariff war despite retaliation the model can be extended to show that the advantage obtained by bei ng part of a large trading unit can help explain the formation of cus toms unions copyright 1988 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

strategic behaviour and the rules for international taxation of capital this paper examines the welfare of a capital exporting or source country and a capital importing or host country under tax credit and tax deduction systems for the international taxation of capital because the two tax systems may create quite different strategic incentives for the countries the authors compare the equilibria in the tax setting game played by the two countries under each system they find that the tax credits system introduces an antitrade bias into the equilibrium contrary to initial impressions and that both capital exporting and capital importing countries will prefer the tax deductions scheme to tax credits copyright 1989 by royal economic society

the role of relocation mobility in tax and subsidy competition abstract in this paper we analyse the role of relocation mobility in tax and subsidy competition our primary result is that increasing mobility of firms leads to increasing net tax revenues under plausible assumptions while enhanced relocation mobility intensifies tax competition it weakens subsidy competition the resulting fall in government subsidy payments can overcompensate the decline in tax revenues leading to a rise in net tax revenues interestingly the opportunity costs of subsidy competition can rise along with net tax revenues we derive these conclusions in a model in which two governments are first engaged in subsidy competition and thereafter in tax competition and firms locate and potentially relocate in response to successive policy choices on taxes and subsidies

taking stock a critical assessment of recent research on inventories empirical and theoretical aspects of inventory behavior became hot topics in the 1950s and early 1960s no one seemed to notice the tension that was developing between the emerging macroeconomic and microeconomic views of inventories macroeconomists routinely thought of inventories as a destabilizing factor yet the prevailing micro theory viewed inventories as a stabilizing factor it was a fascinating question that was barely explored instead somewhat inexplicably interest in inventories dried up as if inventories were of minor economic significance and little intrinsic interest by the early 1980s then economists once again knew something they had known in the 1950s that inventory investment is of first order importance in business cycles but they were also beginning to realize that the standard production smoothing buffer stock model of inventories was in deep trouble this paper focuses on developments since that realization

why is production more volatile than sales theory and evidence on the stockout avoidance motive for inventory holding this paper argues that the macroeconomically interesting features of inventory behavior are well captured by a model in which firms face only demand uncertainty with a nonnegativity constraint on inventories empirical implications of the stockout avoidance model of inventory behavior are derived and then tested on disaggregated automobile industry data the results largely support the model though they suggest a small role for production smoothing as well subsidiary evidence on the relative variance of demand and cost shocks suggests that demand shocks are indeed more important

a theory of expropriation and deviations from perfect capital mobility there are many reasons why commodity trade fails to equate the rewards to factors of production in different countries consequently there is an incentive for factor movements between countries while movements of factors especially capital are important in the world economy they have not been sufficient to equate factor returns among countries the failure of capital flows to equate returns to capital is frequently attributed to political risks and left outside the sphere of economic analysis specifically investments abroad especially in ldc s are said to be more subject to the risk of expropriation or at least to unpredictable changes in the tax and exchange control regime adopted by the host country fears of foreign investors have often been realised williams i975 estimates that about 20 of the value of foreign investments carried into or made during i956 72 in ldc s was expropriated without compensation in this period in the past researchers in disciplines other than economics have been responsible for most of the analysis of expropriations we argue that an important set of economic considerations affect the nature of these impediments to capital mobility and this paper provides a theory of expropriation based on maximising behaviour by host countries and investors we use this theory to identify industry and national characteristics increasing the threat of expropriation and implying large deviations from equal returns on capital and to examine host country and home country policies minimising distortions from the threat of expropriation three broad conclusions follow from the analysis first the threat of expropriation can significantly distort the international allocation of capital even if the act of expropriation is relatively rare in the extreme acts of expropriation would never occur in a world of perfect foresight and rational decision making yet actions by investors to ensure that countries do not expropriate would be distorting second the ability of a country s government to expropriate foreign investments may actually reduce its welfare furthermore a host may be better off if home governments can retaliate against an expropriating country indeed an increase in the penalty imposed on an expropriating country may increase its welfare a government s power to expropriate after investments are made may alasdair smith and an associate editor made numerous valuable suggestions we would also like to thank g m grossman r w jones l a sjaastad n h stern and j e stiglitz for comments much of eaton s work on this paper was completed while he was a visitor at the graduate institute for international studies geneva an earlier version of this paper appeared under the same title as rpds

aggregate inventory behavior in large european economies abstract inventory fluctuations are known to be an important propagation mechanism for u s business cycles this paper compares the significance of inventory fluctuations in the u s with four other major industrial economies in europe a general model of aggregate inventory demand is specified which seeks to encompass the models presented in recent studies of inventory behavior this model is estimated for the large european economies united kingdom west germany france and italy the preferred models that result from this analysis are compared with the empirical evidence for the u s

gradualism in free trade agreements a theoretical justification a notable feature of many recent trade agreements is the gradual rather than immediate reduction of trade barriers in this paper we model trade liberalization as a cooperative relationship that evolves gradually in a non cooperative environment we show that specialization capacity irreversibility and the development of trade partner specific capital increase the benefit of continuing the liberalizing relationship and decrease over time the lowest obtainable self enforcing tariff by increasing the penalty of future defection sunk costs ensure that the self enforcing trading relationship starts slowly but once in progress the level of cooperation continues to improve

gradualism in tax treaties with irreversible foreign direct investment bilateral international tax treaties govern the host country taxation for the vast majority of the world s foreign direct investment fdi of particular interest is the fact that the tax rates used under these treaties are gradually falling although the treaties themselves do not specify any such reductions since there is no outside governing agency to redress treaty violations such reductions must be both mutually beneficial and self enforcing furthermore the optimal tax rates must be less than those initially set otherwise no reductions would be necessary to explain such behavior we model a two country setting with two way capital flows in particular only part of fdi is immediately reversible as the extent of irreversibility increases the likelihood of pareto optimal tax rates obtaining as a self enforcing outcome in the initial period is reduced more modest tax reductions from the non treaty levels are still possible these limited tax reductions generate an increase in bilateral fdi as countries increase the stock of capital in one another further reductions in taxes become self enforcing depending on the extent of irreversibility and asymmetry pareto optimal tax rates may be obtainable in the long run thus the amount of inbound investment a country can attract may be related to the commitment to which its outbound investment binds it this final insight provides an additional rationale for the observed pattern of capital flows in which those countries with the greatest outbound capital flows are also those with the highest inbound flows

joint production quasi fixed factors of production and investment in finished goods inventories inventory investment has long been an important area of inquiry for empirical work in macroeconomics this is due in large measure to the fact that inventory investment is a major source of fluctuations in aggregate output empirical work on inventories however has been dominated by the use of simple univariate flexible accelerators 1 the major objective of this paper is to propose and test a multivariate flexible accelerator model for inventory investment the model is tested with data on finished goods inventories from the manufacturing sector of the u s economy there are two reasons for undertaking such a task first at a theoretical level a univariate flexible accelerator model asserts that investment in say finished goods inventories is proportional to the gap between the desired and actual stocks of finished goods such a model presumes that decisions by firms on finished goods inventories are made independently of decisions on other stocks but theory suggests that when firms make simultaneous decisions on a variety of stocks which includes not only finished goods but also goods in process inventories the size of the work force etc decisions on finished goods will interact with decisions on

the choice of apportionment factors under formula apportionment thispaperinvestigatesthechoiceofapportionmentfactorsunderacorporatetaxsystemofformulaapportionment in contrast to perceived wisdom we show that the apportionment formula contains both mobile capital and immobile labor factors regardless of whether the formula is determined decentrally by jurisdictions or centrally by a central planner the central planner uses the formula as a corrective instrument to internalize fiscal externalities we calibrate the model to the european union and show that replacing the current system of separate accounting by formula apportionment would substantially increase tax revenue and welfare under both centralized and decentralized formula choices

inventories as factors of production and economic fluctuations this paper presents a theory of inventory investment by stage of processing and uses it to examine the role of inventory investment in economic fluctuations the model in which inventories are treated as factors of production is estimated for four durable goods industries three conclusions emerge from the estimation first the estimates generally satisfy the theoretical restrictions second the elasticity of inventory demand with respect to output is high indicating an important accelerator effect finally the estimates suggest that shifts in the demand for inventories are an important source of economic fluctuations copyright 1989 by american economic association

trade inventories and s s the paper presents empirical tests of the s s model of inventory behavior using aggregate retail trade data estimation and testing are based on the probability distributions of inventories derived by caplin 1985 the excess volatility of retailers demand over their consumers demand and the forgetfulness of inventories under s s are emphasized test results indicate that the time series properties of deliveries and sales are consistent with s s and not a quadratic cost model finally when autoregressions of inventories are given an s s rather than a stock adjustment interpretation traditional empirical problems such as low speeds of adjustment are explained

the variability of aggregate demand with s s inventory policies this paper develops a general theory of the aggregate implications of s s inventory policies it is shown that s s policies add to the variability of demand with the variance of orders exceeding the variance of sales overall the s s theory contradicts the widely held notion that retail inventories act as a buffer protecting manufacturers from fluctuating sales in 1951 arrow harris and marschak 3 introduced the s s form of inventory policy the policies are designed for retailers of finished goods who face economies of scale when placing orders with their suppliers to pursue an s s inventory policy the retailer establishes a lower stock point s and an upper stock point s no order is placed until inventories fall to s or below whereupon they are restored to the maximum of s a general proof of the optimality of these s s inventory policies was provided by scarf 13 at the microeconomic level the model has been extensively investigated formulae are available to compute optimal policies e g ehrhardt 6 and these policies are xidely used in industry e g schwartz ed 14 in addition the model has been extended to increasingly complex demand environments e g karlin and fabens 11 in contrast little is known about the macroeconomic implications of s s policies several recent papers have begun to correct this deficiency akerlof has suggested that pursuit of constant threshold money holding policies of the s s variety might be responsible for the observed low short run income elasticity of the demand for money akerlof 1 and akerlof and milbourne 2 in the operations research literature ehrhardt schultz and wagner 7 analyzed the demand environment of a wholesaler supplying several retailers they required that the distinct retailers have independent sales ruling out the analysis of common factors in sales finally simulation results of blinder 4 suggested a role for the s s model in understanding retail sector inventories however the theoretical difficulties with the model remained unresolved blinder commented if firms have a technology that makes the s s rule optimal aggregation across firms is inherently difficult indeed it is precisely this difficulty which has prevented the s s model from being used in empirical work to date blinder 4 p 459 in this paper we present a general theory of the aggregate implications of s s policies our central finding is that s s policies add to the variability of demand with the variance of orders exceeding the variance of sales this result holds even in the presence of common factors in retail sales in addition a close connection

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

the resurgence of inventory research what have we learned abstract recent empirical and theoretical research on business inventories is surveyed and critically evaluated while most inventory research has had macroeconomic motivations we focus on its microtheoretic basis and on potential conflicts between theory and evidence the paper asks two principal questions first how can inventories which are allegedly used by firms to stabilize production nonetheless be a destabilizing factor at the macroeconomic level second why if firms are following the production smoothing model is production more variable than sales in many industries we suggest that the so called s s model may help answer both questions

information as a substitute for inventories abstract in recent years the ratio of inventories to sales in north american manufacturing has fallen without the offsetting increases in unfilled orders or price variation that are predicted by some theoretical models the explanation offered here is that in the face of falling relative costs of communications firms will substitute information for inventories thereby allowing their production systems to absorb a greater part of demand shocks the implicit hypothesis that the demands for communications and inventories are therefore determined simultaneously is tested with data on canadian inventories and on telecommunications between canada and europe and is not rejected

profit taxation and the mode of foreign market entry abstract this paper studies the role of profit taxation for an international firm s decision upon how to penetrate a foreign market through exports or through foreign direct investment fdi and local supply we show that with harmonized taxes the international firm may choose fdi even though this has welfare costs from a global point of view with tax competition the host country can enforce exporting instead of fdi this leads to a nash equilibrium associated with higher world welfare than harmonized taxes thus because of the effect on entry mode tax competition provides heretofore unexplored benefits as compared to tax harmonization

inventories and the volatility of production a stylized fact associated with inventory behavior is that the variance of production exceeds the variance of sales this paper presents a model of production decisions with demand uncertainty that incorporates no nnegativity constraints on inventories even with no productivity shocks optimal behavior by the firm is consistent with this stylized fact either if demand exhibits positive serial correlation or if the firm can backlog excess demand the reason is that a demand shock affects both the actual inventory level given unchanged production and the desired level production must replenish the stock and adjust to the new desired level copyright 1987 by american economic association

the optimal tariff production lags and time consistency the optimal tariff for a large country equals the reciprocal of the foreign export elasticity of supply however if production decisions occur before consumption decisions the ex ante optimal tariff is not time consistent because the ex post elasticity is less than the ex ante elasticity we show all countries are worse off if the large country cannot precommit to its ex ante optimal tariff and that all countries can gain if the large country taxes domestic production of importables

report cards the impact of providing school and child test scores on educational markets this paper studies study the impact of providing school and child test scores on subsequent test scores prices and enrollment in markets with multiple public and private providers a randomly selected half of the sample villages markets received report cards this increased test scores by 0 11 standard deviations decreased private school fees by 17 percent and increased primary enrollment by 4 5 percent heterogeneity in the treatment impact by initial school quality is consistent with canonical models of asymmetric information information provision facilitates better comparisons across providers improves market efficiency and raises child welfare through higher test scores higher enrollment and lower fees

one is almost enough for monopoly it has been argued that two factors product durability and potential entry may force a monopolist to price at marginal cost this article shows that when these two forces coexist the tendency toward competition may be negated first we prove that durable goods oligopolists without commitment powers may attain joint profits arbitrarily close to those of a monopolist with perfect commitment power second we demonstrate that the presence of a potential entrant may enable a durable goods monopolist to act as if he had commitment power thus potential as well as actual entry may restore monopoly power

the oecd model tax treaty tax competition and two way capital flows model tax treaties do not require tax rate coordination but do require that either credits or exemptions be applied to repatriated earnings this contradicts recent models with a single capital exporter where deductions are most efficient i incorporate the fact that capital flows are typically bilateral with symmetric countries credits by both is the unique and efficient treaty equilibrium this equilibrium weakly dominates the nontreaty equilibrium with asymmetric countries the treaty need not offer improvements without tax harmonization with harmonization it is always possible to reach efficient capital allocations while increasing both countries welfares only if neither uses deductions

coordination commitment and enforcement the case of the merchant guild we interpret historical evidence in light of a repeated game model to conclude that merchant guilds emerged during the late medieval period to allow rulers of trade centers to commit to the security of alien merchants the merchant guild developed the theoretically required attributes secured merchants property rights and evolved in response to crises to extend the range of its effectiveness contributing to the expansion of trade during the late medieval period we elaborate on the relations between our theory and the monopoly theory of merchant guilds and contrast it with repeated game theories that provide no role for formal organization

a panel data study on spanish firms inventory investment this paper raises several questions about inventory investment of a sample of 172 big nonfinancial spanish companies inventory investment has been usually explained by two alternative theories the production smoothing model and the s s model first we provide a descriptive analysis based on industry level data to show some shortcomings of the first model then we test a flexible accelerator model using firm level data the results seem to show that inventory investment previous period inventories and sales are closely and significantly related this evidence although not conclusive rejects both the pure production smoothing model and the s s model at the same time our results confirm the view of a target inventory level and the plausibility of the so called stock adjustment model so that the optimal inventory holding buffers sales volatility

the production smoothing model of inventories revisited an error correction specification which nests the linear quadratic production smoothing and stock adjustment models of inventories is estimated on u s seasonally adjusted two digit sic data the restrictions of the general model to the production smoothing specification is accepted for four out of six of the production to stock industries and for total nondurables the estimation results do not suggest any use of inventories to smooth the level of production but there is evidence of smoothing of the rate of change of production for three production to stock industries and for both total nondurables and total durables coefficient estimates may however be biased copyright 1994 by royal economic society

bargaining with commitment choice of techniques and direct foreign investment abstract once a firm has installed a plant in a host country the country will have an incentive to reopen negotiations concerning tax rates this paper examines the incentives for the country to commit to not reopening negotiations a commitment deters the firm from inefficiently reducing the capital intensity of its investment but apparently surrenders tax revenues by not exploiting the country s post entry bargaining power we show that commitment will be optimal as long as the tax system does not place too distortionary a burden on capital and the country has access to capital markets

gradualism in trade agreements with asymmetric countries this paper uses recursive methods to characterize the payoff frontier of self enforcing trade agreements between countries of asymmetric size we show that at points on the frontier where only one country s incentive constraint binds the efficient agreement will be a non stationary one that starts with a positive trade distortion but eventually reaches free trade our analysis illustrates how i relative country size ii consumption smoothing incentives and iii sunk investments affect the form of efficient trade agreements in contrast to previous work on gradualism our results are obtained from a model in which the economic environment is stationary
