Parallel trade,product quality,and welfare

We study the welfare effects of parallel trade (PT) considering investment in quality. We thus revisit the case for PT in research-intensive industries. We find that PT may raise quality, depending on how preferences for quality differ across countries. Conditional on quality, consumer surplus may rise (fall) in the PT-source (PT-recipient) country. While PT reduces ex post welfare, improving quality is a necessary condition for PT to increase welfare ex ante.     

Household inequality, social welfare, and trade

Working with Sen social welfare functions (meaning explicit separability between mean income and income dispersion), we develop a generalized dual approach to tracking household inequality aspects of social welfare in general equilibrium. We highlight how household equity can be examined analytically alongside production efficiency in duality-based models, using our dual framework to explore potential trade-offs between efficiency and equity effects of trade policy. Our results complement the set of standard inequality results in trade theory focused on functional rather than household inequality. We also find that the relative distributional impact of tariffs on welfare is conditional on the initial level of inequality.     

Trade creating free trade areas and the undermining of multilateralism

This paper indicates that the consequences of regional trade agreements for the world trade system may be deceiving—an arrangement's apparent virtue may constitute the source of its drawback. In a model where governments have political, as well as economic, motivations, I show that a free trade area induces its members to reduce protection against the non-members, and to do so sufficiently deeply to generate overall trade creation. Trade creation amplifies the excluded countries’ access to the integrating markets, but also reduces their extra gains from multilateral liberalization. Thus, trade creation can reverse the support of the excluded countries to liberalization on a multilateral basis. This is more likely to happen when governments outside the free trade area are more responsive to special interests.     

Export,FDI and the welfare gains from trade liberalization

This paper extends Melitz and Redding (2015) to analyze the welfare gains from trade liberalization by adding foreign direct investment(FDI). Our model predicts that with FDI activities, welfare gains from trade liberalization will be strictly lower than those in a model without FDI, but only takes exports into account. In addition, the calibrated model indicates that with FDI activities, aggregate welfare reaches its maximum when the fixed export costs are positive rather than 0. Furthermore, we decompose the welfare gains induced by trade liberalization from continuing exporters, and switchers. The results show that in any case, with or without FDI, continuing exporters contribute a larger share to welfare gains than status switching firms.     

Trade liberalization,forward‐looking firms,and welfare

We set up an oligopolistic model with two exporting firms selling to a third market to investigate the welfare implications of trade liberalization when the exporting firms are forward‐looking. The results show that with cost asymmetry trade liberalization encourages the exporting firms to engage in tacit collusion, which may not only be detrimental to the domestic welfare, but also to the consumer surplus of the importing country. Moreover, we find that tacit collusion is less sustainable if the government of the importing country imposes a lower (higher) tariff on the more (less) efficient exporting firm. If a nonforward‐looking or a forward‐looking cost‐efficient domestic firm exists in the importing country, then trade liberalization also encourages tacit collusion.     

Neckties in the tropics: a model of international trade and cultural diversity

Abstract .  Some cultural goods are consumed socially and are characterized by the same consumption network externalities as languages. Also, producers of new cultural goods in any one country draw on the stock of ideas generated by previous cultural production in all countries. For such goods, costless trade and communication tend to lead to the dominance of one cultural style, increasing utility in the short run but reducing quality and welfare in the long run. Increasing protection while keeping communication costs low may stimulate production of cultural goods that are 'compatible' with the dominant style, adding little to the stock of usable ideas.     

Additive versus multiplicative trade costs and the gains from trade liberalizations

This paper addresses welfare effects from trade liberalization in a Melitz ( 2003 ) heterogeneous‐firms trade model including the empirically important per‐unit (i.e., additive) trade costs in addition to the conventional iceberg (i.e., multiplicative) and fixed trade costs. The novel contribution of the paper is the result that the welfare gain for a given increase in trade openness is higher for reductions in per‐unit (additive) trade costs than for reductions in iceberg (multiplicative) trade costs. The ranking derives from differences in intra‐industry reallocations and, in particular, from dissimilar impacts on the number of exporters (i.e., the extensive margin of trade).     

New trade theory,non-price competitiveness and export performance

This paper develops a demand function for Greece's exports of manufactures according to New Trade Theory. Non-price competitiveness plays a vital role in explaining export performance and failure to include it in the export equation may lead to mis-specification error. Foreign income has a moderately high effect on exports in the long run and no effect in the short run. Exports are also sensitive to domestic and competitors' prices in the long run, but cost and price competitiveness elasticities are close to one, indicating that Greek exporters have some ability to compete on the basis of prices.     

Heterogeneous firms,trade liberalization and agglomeration

Abstract In this study, we develop an economic model to examine agglomeration of heterogeneous firms following trade liberalization. In a closed economy, we show that high‐productivity firms are more likely to agglomerate because they benefit more from agglomeration than their low‐productivity counterparts. However, trade liberalization, especially with a high‐productivity partner, favours partial agglomeration; that is, low‐productivity firms relocate away from the region where high‐productivity firms agglomerate. Consequently, the welfare gap between the domestic regions of an economy narrows following trade liberalization. The latter result suggests that trade liberalization promotes regional economic development.     

Countries, regions and trade: On the welfare impacts of economic integration

We study the impact of falling international trade costs and falling national transport costs on the economic geography of countries involved in an integration process. Each country is formed by two regions between which labor is mobile, whereas there is no international mobility. Goods can be traded both nationally and internationally at positive, but different, costs. A decrease in trade costs and/or in transport costs has a direct impact on prices and wages, which allows us to account for the impact of changes in these parameters on the economic geography and welfare of each country. We show that, as trade barriers fall, the benefits of integration come after its costs. We also show that national transport policies are of the beggar-thy-neighbor type. On both counts, policy coordination is required in the process of economic integration.     

The MFN clause,welfare, and multilateral cooperation between countries of unequal size

This paper analyzes MFN in a “competing exporters” model of trade between three countries with unequal endowments and shows that MFN yields higher aggregate welfare than tariff discrimination even as it makes low income countries worse off. Furthermore, in a repeated game of tariff cooperation, multilateral free trade is easier to sustain under MFN punishments relative to discriminatory ones. This conclusion holds even when tariff discrimination takes the form of bilateral trade agreements. Overall, the analysis shows that from the viewpoint of low income countries, MFN and multilateral tariff cooperation are complementary in nature.     

A welfare analysis of unilateral trade and FDI liberalization

This paper uses a heterogeneous‐firms model to examine the pro‐competitive channel through which FDI affects national welfare. The model shows that the country from which FDI originates experiences a welfare gain following liberalization. However, a counterintuitive finding is that the welfare of the host country deteriorates. This is explained by the production relocation process that leads to an increase in the mass of domestic firms in the source country and a decrease in the host country. The model also confirms that unilateral trade liberalization brings a similar result even in the presence of bilateral FDI flows.     

On the welfare effects of trade and investment liberalization

Using a three-factor knowledge- and physical capital model of trade and multinational activity, we consider a set of policy experiments to assess the welfare effects of trade and investment liberalization in general equilibrium. Specifically, we address the question of whether and under which circumstances a single versus a combined trade/investment liberalization strategy or a unilateral versus a bilateral policy change is preferable from a single country's and the world's point of view. The focus of this paper is to look at three relevant questions. First, when is investment liberalization beneficial and when is it harmful for a single economy or the whole world? Second, is pure investment liberalization a welfare maximizing strategy? Third, when is either kind of liberalization (trade, investment, or both) welfare improving and when neither of them?     

The welfare effect of a free trade agreement in the presence of foreign direct investment and rules of origin

This paper investigates the welfare effect of forming a free trade agreement (FTA). To receive tariff‐free treatment, firms must comply with the rules of origin (ROO). Outside firms could undertake either market‐oriented or export‐platform foreign direct investments (FDIs). ROO have the following effects: (i) An infeasible FTA may become feasible by deterring outside firms' FDIs, (ii) an FDI of a less efficient firm could replace that of an efficient firm, or (iii) FDIs made before the FTA is concluded might be eliminated. These potential effects complicate the welfare effect of the FTA and could decrease the consumer surplus.     

Domestic trade protection in vertically-related markets

We consider trade policy in a setting where home country firms are fully dependent on vertically-integrated foreign firms for supplies of a key input. We find that vertically-integrated firms' strategic considerations play an important role and that, in particular, a tariff on final goods may either increase or decrease the domestic price of final goods. The import of final goods is always taxed to extract and shift rents from foreign firms, while the import of intermediate goods can be either taxed or subsidized. The market structure is shown to be an important consideration when making trade policy.     

Globalization and labor market outcomes: Wage bargaining, search frictions, and firm heterogeneity

We introduce search unemployment into Melitz's trade model. Firms' monopoly power on product markets leads to strategic wage bargaining. Solving for the symmetric equilibrium we show that the selection effect of trade influences labor market outcomes. Trade liberalization lowers unemployment and raises real wages as long as it improves average productivity. We show that this condition is likely to be met by a reduction in variable trade costs or by entry of new trading countries. Calibrating the model shows that the long-run impact of trade openness on the rate of unemployment is negative and quantitatively significant.     

Cultural proximity and trade

Cultural proximity is an important determinant of bilateral trade volumes. However, empirical quantification and testing are difficult due to the elusiveness of the concept and lack of observability. This paper draws on bilateral score data from the Eurovision Song Contest, a very popular pan-European television show, to construct a measure of cultural proximity which varies over time and within country pairs, and that correlates strongly with conventional indicators. Within the framework of a theory-grounded gravity model, we show that our measure positively affects trade volumes even if controlling for standard measures of cultural proximity and bilateral fixed effects.     

Regionalism in standards: good or bad for trade?

Abstract.  Regional agreements on standards have been largely ignored by economists and blessed by multilateral trade rules. Using a constructed panel data that identifies the different types of agreements at the industry level, we find that such agreements increase the trade between participating countries but not necessarily with the rest of the world. Harmonization of standards may reduce the exports of excluded countries, especially in markets that have raised the stringency of standards. Mutual recognition agreements are more uniformly trade promoting unless they contain restrictive rules of origin, in which case intra-regional trade increases at the expense of imports from other countries.     

Foreign market conditions and export performance: does ‘crowdedness’ reduce exports?

Abstract This paper analyzes the link between firm exports and the competitive environment in foreign markets. We derive a theory‐based econometric specification linking market‐specific exports to foreign demand and the degree of a market’s ‘crowdedness,’ which depends on the number and efficiency of firms competing there and the barriers impeding their access. Estimates on a large sample of Italian firms indicate that increased crowdedness has reduced Italian exports, but only by 0.2%–0.3% per year. This is substantially less than the contribution of other factors such as higher unit labour costs or weak demand growth in the EU15.     

Privatization, strategic foreign direct investment and host-country welfare

Recent evidence shows that developing countries and transition economies are increasingly privatizing their public firms and at the same time experiencing rapid growth of inward foreign direct investment (FDI). We show that there is a two-way causality between privatization and greenfield FDI. Privatization increases the incentive for FDI, which, in turn, increases the incentive for privatization compared to the situation of no FDI. The optimal degree of privatization depends on the cost difference of the firms, and on the foreign firm's mode of entry.
