Characteristics of Foreign R&D Strategies of Swiss Firms: Implications for Policy

The aim of the paper is, firstly, to identify a number of strategies Swiss firms pursue by performing foreign R&D, expecting that firms, in many instances, are driven by a combination of several motives (mixed strategies). Secondly, we ask whether foreign and domestic R&D are substitutes or complements. Thirdly, we draw some policy conclusions based on results for direct and indirect home-country effects of foreign R&D. By applying cluster analysis, we identified four specific patterns of motives of foreign R&D. In a second step, we investigated whether these clusters effectively may be interpreted as specific types of R&D strategies. To this end, the clusters were characterised in terms of a large number of variables, which, according to the OLI paradigm of FDI, determine foreign R&D. We found that the patterns of the four clusters systematically differ with respect to these theory-related variables. Some clusters represent, in terms of motives, broad-based mixed strategies, whereas others are strongly focused. It turns out that foreign R&D strategies that primarily aim at exploiting capabilities of the domestic headquarters dominate, whereas cost-reducing strategies are of very minor importance. In case of the other two strategies knowledge sourcing is a constituent element, in the first one, knowledge sourcing is at the core, in the second case it is an important element in the frame of a broad-based strategy. The relative importance of the four strategies implies that, on balance, foreign and domestic R&D are complements. Notwithstanding this positive result, it is sensible to take policy actions supporting the economy to capitalise even more on outward FDI in R&D. Policy basically should aim at securing the attractiveness of Switzerland as a location for R&D-intensive headquarters of firms performing foreign R&D, and at enhancing knowledge spillovers from headquarter companies to other domestic firms. The five categories of measures we recommend are part of a framework-oriented policy design rather than of a more interventionist concept.Internationalisation of R&D; Motives of foreign R&D; Foreign R&D strategies; Knowledge spillovers; Home-country effects of outward FDI in R&D

Trade intermediaries, incomplete contracts, and the choice of export modes

The business literature suggests that exporters either use trade intermediaries or own foreign sales representations. Standard trade models are silent about this choice. We develop a model where producers differ with respect to competitive advantage and where trade intermediaries arise endogenously. Intermediaries allow producers to access a foreign market at lower fixed costs, but the lack of enforceable cross-country contracts reduces variable revenue. Producers select into different export modes along their characteristics. Relative prevalence of trade intermediation is stronger the bigger the risk of expropriation in the foreign country and the lower the severity of contractual frictions, the degree of heterogeneity amongst producers, and the elasticity of substitution between varieties. The volume of bilateral trade and the stock of FDI appear as complements in the model. Tentative empirical evidence confirms the main predictions. --International trade,trade intermediation,heterogeneous firms,incomplete contracts

Home Market Effects and the Single-Sector Melitz Model

Increasing-returns-to-scale imperfect competition trade models predict a more than proportionate relationship between the larger country’s share in world endowments and its share in producing firms: the so called home market effect (HME). While this result plays a key role in empirical testing, its theoretical foundation typically posits a linear, friction-free and perfectly competitive outside sector. Replacing this assumption with firm heterogeneity and Melitz (2003) type selection-into-exporting, we demonstrate the existence of a weak and a strong HME. The HMEs are generally non-linear; they are magnified by lower trade costs or more pronounced productivity dispersion. The weak version of the HME continues to hold for general sampling distributions and if the conventional sorting condition fails. In terms of demand shares, a HME holds if demand shocks are due to endowment shocks but reverses in the case of productivity shocks. Finally and in contrast to the model with an outside sector, trade liberalization leads to convergence of real per capita income.home market effect, monopolistic competition, heterogeneous firms, economic geography

Trade intermediation and the organization of exporters

The business literature and recent descriptive evidence show that exporting firms typically require the help of foreign trade intermediaries or need to set up own foreign wholesale affiliates. In contrast, conventional trade theory models assume that producers can directly access foreign consumers. This paper introduces intermediaries in an international trade model where producers differ with respect to productivity as well as regarding their varieties' perceived quality and tradability. We assume that trade intermediation is prone to frictions due to the absence of enforceable cross-country contracts while own wholesale subsidiaries require capital investment. We derive the sorting pattern of firms according to their degree of competitive advantage and show how the relative prevalence of intermediation depends on the degree of heterogeneity among producers, on the importance of market-specificity of goods, or on expropriation risk. We use US export data for 50 sectors and 133 destination countries to check the empirical validity of this predictions and find robust empirical support. --Trade intermediation,international trade, heterogeneous firms,incomplete contracts

Trade Intermediation and the Organization of Exporters

The business literature shows that exporting firms typically require the help of foreign trade intermediaries or need to set up own foreign wholesale affiliates. In contrast, conventional trade theory models assume that producers can directly access foreign consumers. This paper models the endogenous emergence of intermediaries in an international trade model where producers differ with respect to productivity as well as regarding their varieties' perceived quality and tradability. We assume that trade intermediation is prone to frictions due to the absence of enorceable cross-country contracts while own wholesale subsidiaries require capital investment. We derive the sorting pattern of firms according to their degree of competitive advantage and show how the relative prevalence of intermediation depends on the degree of heterogeneity among producers, on the importance of market-specificity of goods, or on expropriation risk. We use US export data for 50 sectors and 133 destination countries to check the empirical validity of this predictions and find robust empirical support.

Sorting It Out: Technical Barriers to Trade and Industry Productivity

Trade economists traditionally study the effect of lower variable trade costs. While increasingly important politically, technical barriers to trade (TBTs) have received less attention. Viewing TBTs as fixed regulatory costs related to the entry into export markets, we use a model with heterogeneous firms, trade in differentiated goods, and variable external economies of scale to sort out the rich interactions between TBT reform, input diversity, firm-level productivity, and aggregate productivity. We calibrate the model for 14 industries in order to clarify the theoretical ambiguities. Overall, our results tend to suggest beneficial effects of TBT reform but also reveal interesting sectoral variation.Heterogenous Firms, Single European Market, International Trade, Technical Barriers to Trade, Regulatory Costs

Optimal Tariffs, Retaliation and the Welfare Loss from Tariff Wars in the Melitz Model

This paper characterizes analytically the optimal tariff of a large one-sector economy with monopolistic competition and firm heterogeneity in general equilibrium, thereby extending the small-country results of Demidova and Rodriguez-Clare (JIE, 2009) and the homogeneous firms framework of Gros (JIE, 1987). The optimal tariff internalizes a markup distortion and a terms of trade externality. It is larger the higher the dispersion of firm-level productivities, and the bigger the country's relative size or relative average productivity. Furthermore, in the two-country Nash equilibrium, tariffs turn out to be strategic substitutes. Small or poor economies set lower Nash tariffs than large or rich ones. Lower transportation costs or smaller fixed market entry costs induce higher equilibrium tariffs and larger welfare losses relative to the case of zero tariffs. Similarly, cross-country productivity or size convergence increases the global welfare loss due to non-cooperative tariff policies. These results suggest that post WWII trends have increased the relative merits of the WTO.optimal tariffs, retaliation, tariff wars, heterogeneous firms, World Trade Organization, Nash equilibrium

The heterogeneous effects of Chinas accession to the world trade organization

Chinas accession to the World Trade Organization (WTO) in 2001 was a massive boostfor the multilateral trading system. We present descriptive evidence on the trade effects of Chinas WTO accession. Moreover, we combine the most recent approaches from the gravity literature of international trade to provide a causal analysis of the effects of Chinas WTO accession on bilateral trade with other WTO members. We find that the trade effectis positive on average. Moreover, we document substantial heterogeneity in the trade ef-fects across Chinas trading partners. These findings seem to be consistent with Chinasposition in global value chains

Readdressing the trade effect of the Euro: Allowing for currency misalignment

We know that euro-area member countries have absorbed asymmetric shocks in ways that are inconsistent with a common nominal anchor. Based on a reformulation of the gravity model that allows for such bilateral misalignment, we disentangle the conventional trade cost channel and trade effects deriving from 'implicit currency misalignment'. Econometric estimation reveals that the currency misalignment channel exerts a significant trade effect on bilateral exports. We retrieve country specific estimates of the euro effect on trade based on misalignment. This reveals asymmetric trade effects and heterogeneous outlooks across countries for the costs and benefits from adopting the euro. --Euro,gravity model,exchange rates,purchasing power parity,trade imbalances
