Agglomeration and tax competition

Tax competition may be different in ‘new economic geography settings’ compared to standard tax competition models. If the mobile factor is completely agglomerated in one region, it earns an agglomeration rent which can be taxed. Closer integration first results in a ‘race to the top’ in taxes before leading to a ‘race to the bottom’. We reexamine these issues in a model that produces stable equilibria with partial agglomeration in addition to the core-periphery equilibria. A bell-shaped tax differential also arises in our model. Therefore, the ‘race to the top’ result generalises to a framework with partial agglomeration.     

Agglomeration,backward and forward linkages: evidence from South Korean investment in China

Abstract With a firm‐level data set, we study the location decision of South Korean multinationals across China's regions. Our conditional logit estimates confirm agglomeration effects along industry and along national lines. We add an upstream and downstream (backward and forward) linkage effect. We find that the presence of upstream and downstream South Korean affiliates significantly increases the likelihood that a South Korean multinational invests in a particular region. However, linkages that do not differentiate by nationality do not seem to matter much. As such, our analysis of investors' location choice brings together two perspectives: linkages and agglomeration along national lines.     

Trade costs and the timing of competition policy adoption

Abstract This paper first presents stylized evidence showing how the date of the adoption of competition policy is correlated with country size. Smaller countries tend to adopt competition policy later. We then present a theoretical model with countries of different size, trade costs, and firms competing à la Cournot. In the model we show that reduced trade costs following from increasing globalization affect countries differently depending on their size. This has implications for the incentives to introduce competition policy. The predictions of the model are consistent with the empirical regularity presented.     

Relative wages and trade-induced changes in technology

We develop a model where trade liberalization leads to skill-biased technological change, which in turn raises the relative return to skilled labor. When firms get access to a larger market, the relative profitability of different technologies changes in favor of the more skill-intensive technology. As the composition of firms changes to one with predominantly skill-intensive firms, the relative demand for skilled labor increases. This way, we establish a link between trade, technology and relative returns to skilled and unskilled labor.     

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.     

Skills, agglomeration and segmentation

This paper studies the role of skill heterogeneity in “new economic geography” models of location. In our setting, products are both horizontally and vertically differentiated, and producing higher quality goods requires workers with higher skills. Selling to customers based in a different location entails iceberg-type transport costs and additional “communication costs” consisting of a fixed quality loss. We show that the presence of pecuniary externalities creates a mechanism which always promotes spatial sorting of workers according to their skill levels. In particular, in all stable equilibria, workers with higher skill choose to stay in the location where aggregate skill and income is higher, while the less skilled stay in the other.     

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.     

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.     

Competition in the traditional sector does not matter for the ‘Core–Periphery’ model

We modify Paul Krugman’s (1991) ‘Core–Periphery’ model by replacing the traditional competitive sector with a monopolistically competitive one. We show that the structure of spatial equilibria remains the same as in the original model. This result continues to hold true under Cournot or Bertrand oligopolistic competition with free entry in the traditional sector. The key factor that explains why the nature of competition in the traditional sector does not matter for the spatial equilibria is constant expenditure shares–due to nested Cobb–Douglas and CES preferences–which imply that trade in the traditional sector is independent from its sectoral characteristics.     

Firms agglomeration and unions

Economic geography models predict the agglomeration of manufacturing activies only if the workforce is mobile. Still, as the E.U.'s experience shows, core-periphery patterns exist even though the workforce is rather immobile. The paper provides a theoretical explanation for such core-periphery patterns through the effect that unions have on firms’ incentive to agglomerate in a region. The paper offers fully analytical results about location equilibria and some interesting welfare properties.     

Unionization,international integration,and selection

Abstract We study how unionization affects competitive selection between heterogeneous firms when wage negotiations can occur at the firm or at the profit‐centre level. With productivity specific wages, an increase in union power has: (i) a selection‐softening; (ii) a counter‐competitive; (iii) a wage‐inequality; and (iv) a variety effect. In a two‐country asymmetric setting, stronger unions soften competition for domestic firms and toughen it for exporters. With profit‐centre bargaining, we show how trade liberalization can affect wage inequality among identical workers both across firms (via its effects on competitive selection) and within firms (via wage discrimination across destination markets).     

New economic geography meets Comecon

We analyse the internal spatial wage and employment structures of the Czech Republic, Hungary, Poland, Slovakia and Slovenia, using regional data for 1996–2000. A new economic geography model predicts wage gradients and specialization patterns that are smoothly related to the regions’ relative market access. As an alternative, we formulate a ‘Comecon hypothesis’, according to which wages and sectoral location are not systematically related to market access except for discrete concentrations in capital regions. Estimations support both the NEG (new economic geography) prediction and the Comecon hypothesis. However, when we compare internal wage and employment gradients of the five new member states with those of Western European countries, we find that the former are marked by significantly stronger discrete concentrations of wages and service employment in their capital regions, confirming the ongoing relevance of the Comecon hypothesis.     

Economic integration and the profitability of cross-border mergers and acquisitions

The 1990s was a decade of increased economic integration. The decade also witnessed a sharp increase in cross-border mergers and acquisitions. From a theoretical perspective, the increase in international mergers in more integrated economies is rather puzzling. It is a well-established result that due to the “business stealing effect”, mergers in integrated markets are not likely to be profitable. A reasonable conjecture would therefore be that closer integration of markets would reduce the attractiveness of cross-border mergers and acquisitions. The present paper demonstrates that this is not necessarily the case: Economic integration may trigger cross-border acquisitions by reducing the business stealing effect and by reducing the reservation price of the target firm. The paper thus provides explanations to the observed increase in cross-border mergers in a world of more integrated economies.     

Does distance reflect more than transport costs?

We decompose the effect of distance on intercity retail price dispersion in US into transport and non-transport cost components. We find that distance contains more information than transport costs. Care should be taken in interpreting distance effect as transport costs only.     

Agglomeration economies and location choice: Foreign direct investment in Hungary1

Since the beginning of the transition process, Hungary has attracted a significant amount of foreign direct investment (FDI), although this is unevenly distributed among the twenty Hungarian counties. This paper examines the determinants of FDI at a regional level in Hungary and more particularly assesses the importance of agglomeration effects among determinants. A panel model of the location determinants of FDI in Hungary is developed and estimated. Empirical testing suggests that counties with higher labour availability, greater industrial demand and higher manufacturing density attract more FDI. Surprisingly, higher unit labour costs attract FDI. In addition, inter‐industrial agglomeration economies and infrastructure availability are found to be important.     

Winners and losers: a micro-level analysis of international outsourcing and wages

Abstract.  Our paper investigates the link between international outsourcing and wages utilizing a large household panel and combining it with industry-level information on industries' outsourcing activities from input-output tables. This approach avoids problems such as aggregation bias, potential endogeneity bias, and poor skill definitions that commonly hamper industry-level studies. We find that outsourcing has had a marked impact on wages. Applying two alternative skill classifications, we find evidence that a 1 percentage point increase in outsourcing reduced the wage for workers in the lowest skill categories by up to 1.5%, while it increased wages for high-skilled workers by up to 2.6%. This result is robust to a number of different specifications.     

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).     

Trade between symmetric countries,heterogeneous firms,and the skill premium

Abstract This paper examines the effects of trade liberalization between symmetric countries on the skill premium. I introduce skilled and unskilled labour in a model of trade with heterogeneous firms à la Melitz (2003) and assume a production technology such that more productive firms are more skill intensive. I show that the effects of trade liberalization on wage inequality crucially depend on the type of trade costs considered and on their initial size. While fixed costs of trade have a potentially non‐monotonic effect on the skill premium, a drop in variable trade costs unambiguously and substantially raises wage inequality.     

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.
