what determines bits abstract similar to bilateral or regional preferential trade agreements ptas bilateral investment treaties bits have proliferated over the past 50 years the purpose of this study is to provide the first systematic empirical analysis of the economic determinants of bits and of the likelihood of bits between pairs of countries using a qualitative choice model in a manner consistent with explaining ptas we develop the econometric specification for explaining the two based upon a general equilibrium model of world trade and foreign direct investment with three factors two products and trade and investment costs among multiple countries in the presence of national and multinational firms the empirical model for bits and ptas is bivariate in nature and supports a set of hypotheses drawn from the general equilibrium model using the preferred empirical model for a sample of 12 880 country pairs in the year 2000 we predict correctly 88 of all pairs with a bit and a pta 81 with a bit but no pta and 84 with a pta but no bit

scale economies in factor supplies international trade and migration this paper incorporates externalities generated by human capital into the heckscher ohlin samuelson framework to examine the patterns of international trade and migration individuals endowed with different levels of human capital choose to become either unskilled or skilled workers national scale economies with respect to human capital play an important role in endogenously determining these factor supplies and yield a number of interesting patterns of trade and migration migration could reinforce comparative advantage both skilled and unskilled workers could migrate in the same direction

adapting the knowledge capital model of the multinational enterprise to trade and investment in business services at some conceptual level trade in goods and services are not that much different however the speed at which trade and foreign investment in services is growing along with the fact that the barriers to these activities are quite different from those for trade in goods prompts us to take a more careful look the paper begins with a general discussion about the various policies and technological constraints that impact foreign trade and the establishment of foreign commercial presence in intermediate business services we then discuss which characteristics an accurate modelling approach must capture following that we develop a model that allows for different regimes of trade and or foreign affiliate production in services using markusen s knowledge capital model simulations show that the pattern of service firm headquarters and office locations can differ considerably depending on whether it is trade investment or both that are either liberalised or become technologically feasible our results find that the welfare and factor price consequences are quite similar across the different scenarios

immigrant specificity and the relationship between trade and immigration theory and evidence studies routinely document that immigrant employment concentrates in non traded goods sectors and that many immigrants have low inter sectoral mobility we consider these observed characteristics of immigrant employment with regard to the question of how immigration affects a nation s pattern of production and trade we model an economy producing three goods one is non traded domestic labor and capital are domestically mobile but internationally immobile allowing that some new immigrants will become specific to the non traded goods sector the model indicates that the effects of immigration on output and trade depend importantly on the sectoral pattern of employment of both new and existing immigrants empirical investigation in a panel data set of oecd countries supports the model s prediction that immigration raises the output of non traded goods consistent with the model we also find that immigration and trade are complements given its empirical support the model s implications for immigration policy are then discussed

do state borders matter for u s intranational trade the role of history and internal migration empirical evidence of the impact of borders on international trade flows using the gravity equation approach abounds this paper examines the empirical relevance of state borders in u s interstate trade for various specifications of the gravity equation we find a large and economically significant subnational border effect for some specifications however two model specifications drastically reduce if not eliminate the border effect i dynamic panel specifications controlling for past levels of trade and ii models conditioning on internal migration les resultats empiriques de l analyse des impacts des frontieres sur les flux de commerce international en utilisant les modeles de gravite sont devenus monnaie courante ce texte examine l impact des frontieres entre etats a l aide de cette technique il s avere que les effets de frontieres infranationales sont grands et significatifs pour certaines specifications du modele cependant deux specifications du modele reduisent dramatiquement s ils n eliminent pas l effet de frontiere i des specifications qui prennent en compte les niveaux anterieurs de commerce et ii des specifications qui dependent de la migration interne

international trade agreements and international migration despite large potential economic gains bilateral and multilateral negotiations focusing on liberalisation of migration have not shared the high profile of international trade negotiations and agreements migration and trade have been traditionally viewed rather separately and the relevance of the many and complex interdependencies has been given remarkably little attention in the literature to date in this article we focus on the two way interaction between international migration and agreements designed to enhance cross border trade and investment liberalisation of international trade in services and in the movement of people potentially offers much greater economic gains than liberalisation of remaining barriers to goods trade however progress within multilateral frameworks is fraught with difficulty the world trade organization s general agreement on trade in services gats has yielded little real progress so far and negotiations within more flexible unilateral and bilateral frameworks are likely to be more successful in liberalising the movement of labour we discuss a range of specific examples focusing particularly on the interesting case of new zealand we find that trade agreements are increasingly including agreements on migration though typically favouring temporary migration and involving numerically modest quotas we conclude that migration regulatory frameworks are likely to be further and more strongly linked to trade and investment agreements in the future particularly given changing economic and demographic forces the primary focus of migration policies may nonetheless remain different from that of trade policies while further migration liberalisation is likely to be through bilateral and regional agreements it will be important to try to lock in the gains of such agreements while simultaneously working to consolidating these in a way that will help to facilitate future multilateral agreement

in search of substitution between foreign production and exports abstract are foreign production and exports substitutes or complements standard theory of the multinational corporation mnc assumes substitution while previous empirical work examining the relationship has generally found strong evidence of complementarity this study examines product level data which more closely fits the assumption of a single product firm often used in mnc theory and finds substantial evidence for both a substitution and a complementarity effect between affiliate production and exports with japanese automobile parts for the us market i also test for and find evidence of substitution using product level data on a set of japanese produced final consumer goods

foreign direct investment and exports a time series approach the impact of the accelerated internationalization of the last decade on the austrian economy is a controversial issue granger s concept of casuality is used to investigate one aspect of the internationalization of production the realtionship between foreign outward direct investment and exports using aggregate flow data from the austrian economy the stationarity of the time series is examined and cointegration tests for the adequacy of the multivariate time series approach are performed the estimation results suggest significant causality of austrian foreign outward direct investment and exports in both directions impulse response analysis and varience decomposition show a very slow dynamic response of both variables to exogenous shocks of the other it furthermnore indicates the possiblity of a positive effect of exogeneously increased foreign direct investment on exports and a negative effect of export shocks on foreign direct investment however significant long run effects are not established

oligarchies and development in a global economy a tale of two elites this paper studies how comparative advantage and the political elites endowments shape long run performance in economies with imperfect political institutions the trade regime interacts with industrial policy and regulations on capital mobility in governing capital accumulation in a capital scarce economy capitalist oligarchs striving for import substitution industrialization isi initially shelter the economy from trade while promoting industrial policies that promote total factor productivity growth in the manufacturing sector this gradually shifts the comparative advantage toward manufacturing and renders the economy attractive to foreign investors allowing for trade and foreign capital inflows are thus complementary policies that spur growth in the capital oligarchy by contrast landed oligarchs in a capital scarce economy favor openness to trade at an early stage of development neglect industrial policies and block foreign capital to maximize extractable rents the policy mix causes the economy to stagnate consistent with the experiences of south korea and argentina in the postwar era the model predicts that the success of isi policies depends crucially on the conditions governing the incentives for capital accumulation jel f10 f20 p40 p50 o10 o24

explaining the absence of international factor price convergence abstract as capital markets have become integrated factor prices have not converged as expected this paper provides an explanation the key observation is that non specific output risks are borne by capital making international portfolio diversification a dominant strategy capital market integration can elicit many patterns of factor price response under this circumstance factor prices will move in parallel if countries are identical when countries differ factor prices may diverge or even have their relative sizes reversed the integration of capital markets affects welfare through changes in risk and in overall returns to savings welfare need not improve

trade migration costs and asymmetric migration patterns increase in trade has an asymmetric impact on emigration by skill types for a developing country cost of migration is a dynamic function of the type of emigration and it determines a complementary relation between emigration of skilled workers and expansion of trade emigration of unskilled workers is a substitute however and these outcomes coexist with endogenously determined emigration rates that depend crucially on wage responses among the own skill types at the source additionally asymmetric emigration patterns increase wage inequality

the regional consequences of international trade with interregional capital mobility abstract this paper examines the resource allocation and welfare effects of international trade when a nation is composed of distinct regions and capital is mobile interregionally the introduction of capital mobility significantly alters the regional consequences of free trade it is shown for example that it is possible that the source of the nation s export expansion is the region that is at a technological disadvantage in the production of the export good also that region whose comparative advantage coincides with that of the nation as a whole may see its welfare decrease with free trade

can a small social pension promote labor force participation evidence from the colombia mayor program one of the primary motivations behind the establishment of noncontributory pension programs is to allow beneficiaries to retire from the labor force yet as with other unconditional cash transfer schemes their aggregate effects may be more complex using panel data and instrumental variable techniques this paper shows that the effect of one such program colombia mayor has been to raise the labor force participation of relatively younger male beneficiaries this increase occurred precisely in the occupations with characteristics that are likely to require some up front investment the paper concludes that the transfer effectively loosened the liquidity constraints to remaining in these occupations however no such effect is found among women or older beneficiaries

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

factor trade and goods trade world equilibria with trade in both goods and some factors are studied when international factor endowment differences are the cause of trade a generalized heckscher ohlin theorem is presented the goods trade patterns with and without factor trade are compared factor trade and goods trade tend to be substitutes complements if traded and non traded factors are cooperative non cooperative

why do rich countries prefer free trade over free migration the role of the modern welfare state abstract according to traditional trade theory heckscher ohlin free trade and free migration are equivalent measures of economic integration leading both to an equalization of factor prices this prediction is in sharp opposition to the observed preference of rich countries for free trade over free migration we provide an explanation for this inconsistency the redistribution policies in the countries social welfare in countries with a relatively small number of low skilled native workers is higher with free trade than with free migration due to redistribution of income towards immigrating workers

retailer s economic order quantity when the supplier offers conditionally permissible delay in payments link to order quantity abstract trade credit financing is increasingly recognized as an important strategy to increase profitability in inventory management we revisit an economic order quantity model under conditionally permissible delay in payments in which the supplier offers the retailer a fully permissible delay of m periods i e there is no interest charge until m if the retailer orders more than or equal to a predetermined quantity w however if the retailer s order quantity is less than w then the retailer must make a partial payment to the supplier and enjoy a permissible delay of m periods for the remaining balance in this paper we extend the mentioned eoq under conditionally permissible delay in payments to complement some shortcomings of the model by contrast to the differential calculus method we propose a simple arithmetic geometric method to solve the problem furthermore we establish some discrimination terms to identify the unique optimal solution among three alternatives and explain those theoretical results by simply economical interpretations finally we solve several numerical examples to illustrate the theoretical results and obtain some managerial implications

the economics of foreign direct investment and trade with an application to the u s food processing industry this article investigates the determinants of foreign direct investment and its relationship to trade in the u s food industry a multinational corporation maximizes profits by choosing between production at home which is exported and production in a host country this introduces the possibility that foreign affiliate sales can substitute and or complement exports the empirical framework consists of a four equations system with foreign affiliate sales exports affiliate employment and fdi as endogenous variables the results confirm small substitution between foreign sales and exports and that the host country s protection policies affect the decision to invest abroad

the theorems of international trade with factor mobility abstract this paper addresses the relation between goods trade and international factor mobility in general terms the basic theorems of international trade suitably interpreted are shown to hold in their strong versions if the number of international markets for goods and factors is at least as large as the number of factors the crucial dimensionality issue is hence not the relative number of goods and factors per se but the number of international markets relative to the number of factors only the price version of the heckscher ohlin theorem fails to be essentially preserved by this condition

liberalising temporary movement of natural persons an agenda for the development round we discuss liberalising the temporary mobility of workers under mode 4 of the gats particularly the movement of medium and low skilled service providers between developing and developed countries such mobility potentially offers huge returns a flow equivalent to three per cent of developed countries skilled and unskilled work forces would generate an estimated increase in world welfare of over us 150 billion shared fairly equally between developing and developed countries the larger part of this emanates from the less skilled essentially because losing higher skilled workers cuts output in developing countries severely the mass migration of less skilled workers raises fears in developed countries for cultural identity problems of assimilation and the drain on the public purse these fears are hardly relevant to temporary movement however the biggest economic concern from temporary mobility is its competitive challenge to local less skilled workers but as populations age and the average levels of training and education rise developed countries will face an increasing scarcity of less skilled labour temporary mobility thus actually offers a strong communality of interest between developing and developed countries the remainder of the paper looks at the gats provisions on mode 4 and the commitments that have been made under it the paper reviews several official proposals for the doha talks including the very detailed one from india and considers several countries existing schemes for the temporary movement of foreign workers many countries have long had bilateral foreign worker programmes and some regional agreements provide for liberal and flexible movement these show what is feasible and how concerns can be overcome we caution that to be useful any wto agreement must increase mobility not just bureaucratise it the paper concludes with some modest and practical proposals we suggest inter alia that licensing firms to arrange the movement of labour is the most promising short term approach to increasing temporary mobility

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

should export share requirements be implemented under quota protection in this paper the authors develop a model to analyze the effects of export share requirements when a quota is in place they show that when foreign capital is located in specific economic activity zones identified with the importable sector an increase in export share requirements reduces welfare owing to the price induced higher payments to foreign capital

international trade and the internal organization of firms an evolutionary approach masahiko aoki and others have distinguished two alternative modes for a firm s internal organization we argue that the profitability of each mode depends on the distribution of firms across modes and on the general economic environment we characterize the evolutionary equilibria in both a parametric and a general model and argue that corner equilibria predominate we analyze the effects of trade between the two countries in a outputs only and b inputs factors as well as outputs our most striking conclusion is that in case b a less efficient mode can displace a more efficient mode when trade barriers are sufficiently low

trade and capital flows a financial frictions perspective the classical heckscher ohlin mundell paradigm states that trade and capital mobility are substitutes in the sense that trade integration reduces the incentives for capital to ow to capital scarce countries in this paper we show that in a world with heterogeneous nancial development the classic conclusion does not hold in particular in less nancially developed economies south trade and capital mobility are complements within a dynamic framework the complementarity carries over to nancial capital ows this interaction implies that deepening trade integration in south raises net capital in ows or reduces net capital out ows it also implies that at the global level protectionism may back re if the goal is to rebalance capital ows when these are already heading from south to north our perspective also has

factor mobility trade and welfare abstract the paper develops a north south model which is driven by scale economies in the modern sector the model predicts that skilled and unskilled labor migrate from south to north and capital migrates from north to south migration of skilled labor and capital exhibits complementarity with trade while migration of labor may exhibit complementarity or substitutability if the terms of trade effects are ignored small movements of all factors affect the welfare of the population in south negatively and of that in north positively the effects of migration on the terms of trade are ambiguous in general

aid and migration substitutes or complements this paper investigates the impact of aid on migration and identifies two channels bilateral aid influences migration by enhancing the information about labor market conditions in the destination country attraction effect total aid correlates with migration through increasing expenditure financing and hence wages in countries of origin push effect we compute the critical level of income above which emigration and income are substitutes which is about us 7 300 per capita in ppp 2000 prices for example brazil or russia we argue that for countries below this threshold there is a trade off between aid and migration policies a tightening of the migration policy is equivalent to a reduction of the level of aid by about 24 a comparison of skilled and unskilled migrations shows that the former are more sensitive to the attraction effect than the latter

are international trade and factor mobility substitutes abstract this paper analyzes whether factor flows and commodity trade are substitutes or complements i e whether increasing the level of one impacts adversely or favorably on the volume of the other it derives with the aid of a new general equilibrium framework of the world which allows possible differences in factor endowments tastes and technologies across the two trading countries the necessary and sufficient condition for substitutability and complementarity the results are then further examined in two special cases a survey of different concepts of substitutability and complementarity which have appeared in the literature is also given

free trade and global warming a trade theory view of the kyoto protocol this paper demonstrates how three important results in environmental economics true under mild conditions in closed economies are false or need serious amendment in a world with international trade in goods since the three results we highlight have framed much of the ongoing discussion and research on the kyoto protocol our viewpoint from trade theory suggests a re examination may be in order specifically we demonstrate that in an open trading world but not in a closed economy setting 1 unilateral emission reductions by the rich north can create self interested emission reductions by the unconstrained poor south 2 simple rules for allocating emission reductions across countries such as uniform reductions may well be efficient even if international trade in emission permits is not allowed and 3 when international emission permit trade does occur it may make both participants in the trade worse off and increase global emissions
