International Organization of Production with Heterogeneous Firms

This paper presents a North–South model with differentiated goods being produced in the North. Each differentiated final good requires both management and manufacturing services as inputs, and firms are heterogeneous with regard to their productivity levels in providing these inputs. Two scenarios of relocating manufacturing to the South, which are interpreted to correspond to vertical foreign direct investment (FDI) and offshoring, are investigated. In both cases there is a minimum level of management productivity required for firms to benefit from relocation of manufacturing to the South. In the case of offshoring, productivity and profit gains are relatively larger for firms with low initial manufacturing productivity. Firms with high initial productivity in both aspects choose not to offshore owing to the presence of fixed costs. The model is subsequently used to examine the implications of global economic integration on the type of firm that exits an industry, changes production location or keeps manufacturing domestically.     

Complementarity,Linkages between Firms,and the Effect of Entry Costs on Productivity

In a general equilibrium model where firms are heterogeneous in terms of productivity, we introduce differentiated goods in production that are not perfect substitutes, as well as intermediate inputs needed to produce those goods. We show that an increase in either the complementarity of differentiated goods or the share of intermediate inputs in gross output, significantly increases the negative effect of entry costs on total factor productivity (TFP) and output per worker. We also find that the effect of complementarity is quantitatively stronger. If we assume an empirically plausible value for the elasticity of substitution between differentiated goods, then the model considerably improves its ability to reproduce the observed negative relationship between entry costs and TFP or output per worker.     

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.     

Less Developed Countries,Tourism Investments and Local Economic Development

This paper analyzes the forward linkages of a multinational's investment in a resort that kicks off tourism activity in a less developed country. We show that, under quite natural assumptions, overnight stays are increasing in the number of differentiated tourism‐related goods and services. These goods and services, if supplied by the local community, represent forward linkages of FDI in tourism. We investigate the multinational's incentives to promote, reduce or eliminate these forward linkages and the effectiveness of some policy instruments available to a local government to leverage on the presence of FDI and to stimulate domestic entrepreneurship.     

Trade and direct investment in producer services and the domestic market for expertise

Abstract.  Foreign producer services can provide substantial benefits for domestic firms. We build on earlier monopolistic‐competition models of intermediate producer services in this paper. Results show that: (1) while foreign services are partial‐equilibrium substitutes for domestic skilled labour, they may be general‐equilibrium complements, (2) service trade can provide crucial missing inputs that reverse comparative advantage in final goods, (3) the 'optimal' tax on imported services may be a subsidy, and (4) in our dynamic formulation, there may be earnings losses for immobile workers along a transition path that suggest potentially important equity consequences of reform.

Demand complementarities and cross‐country price differences

Empirical studies document that markups vary across destinations. This paper proposes a novel mechanism to explain variation in markups: consumers’ utility from final goods and services depends on their consumption of complementary goods and services. In countries with more complementary goods and services, consumer demand is less elastic, enabling monopolistically competitive firms to charge higher prices. The paper provides empirical evidence documenting a dependence of prices on demand complementarities.     

Offshoring and jobs: The myriad channels of influence

Offshoring reallocates jobs inside firms, between firms, and across sectors, affecting the economy-wide unemployment rate. We study these channels in a model with labor market frictions and two sectors—a differentiated-good sector comprising heterogeneous firms that can offshore, and a homogeneous-good sector. A decline in offshoring costs affects intrafirm and intrasectoral reallocation of jobs in the differentiated-good sector through a selection effect, a productivity effect, and a job-relocation effect. The key parameters determining the impact of offshoring on jobs at various margins, as well as on the economy-wide unemployment rate, are the elasticity of substitution between inputs, the elasticity of substitution between varieties of differentiated goods, and the elasticity of demand for differentiated goods as a whole. Changes in search frictions affect unemployment both directly and through their interaction with offshoring.     

Technology transfers,foreign investment and productivity spillovers

This paper explores the relationship between foreign direct investment (FDI) and the productivity of host country domestic firms. We rely on a specially designed survey of over 4000 manufacturing firms in Vietnam, and separate out productivity gains along the supply chain (obtained through direct transfers of knowledge/technology between linked firms) from productivity effects through indirect FDI spillovers. In addition to identifying indirect vertical productivity spillovers from FDI, our results show that there are productivity gains associated with direct linkages between foreign-owned and domestic firms along the supply chain not captured by commonly used measures of spillovers. This includes evidence of productivity gains through forward linkages for domestic firms which receive inputs from foreign-owned firms.     

Employment,job turnover,and trade in producer services: UK firm‐level evidence

Abstract We provide the first firm‐level evidence of the impact of the trade in producer services (‘offshoring’) on the labour market. Using a new data set from the UK that measures trade in services at the firm level, we find no evidence that importing intermediate services is associated with job losses or greater worker turnover. Using regression to control for observable differences between firms that import service inputs and those that do not, we show that firms that start importing intermediate services experience faster employment growth than equivalent firms that do not. This seems likely to be the result of positive demand shocks, which cause a simultaneous increase in employment, output, and use of imported service inputs.     

Standardization of intermediate goods and international trade

Abstract.  This paper analyzes the relationship between standardization of intermediate inputs and international trade. We employ a two-country, general equilibrium model with differentiated manufacturing goods. Production of manufacturing goods requires specific intermediate inputs, which can be either specialized or standardized. Standardization and the pattern of trade are determined endogenously in our model. In this framework we derive the effects of trade integration, that is, a decline in trading costs for intermediate goods, on the equilibrium outcome.     

Selection,Market Size and International Integration: Do Vertical Linkages Play a Role?

We analyze how increases in the market size and in the level of international integration affect the process of selection among firms with heterogeneous productivity levels when they are interconnected by vertical linkages. We show that when vertical linkages among firms are relatively weak (strong), an increase in the market size softens (toughens) the competition facing firms in this market and more firms of a lower (higher) efficiency survive, increasing (decreasing) the welfare level. Moreover, an increase in the level of economic integration softens competition only for intermediate vertical linkages, worsening the welfare level only for strong linkages.     

Vertical technology transfer and the welfare implications of patent protection

Significant amount of vertical technology transfer occurs between developed and developing-country firms, and many trading companies from developing countries create competition in the developed countries, yet the literature on intellectual property rights did not pay considerable attention to these aspects. In a Cournot oligopoly with vertical technology transfer, we show that patent protection in the developing country raises developed-country welfare if the following three conditions hold together: (i) patent protection in the developing country deters entry in the final goods market, (ii) the marginal cost difference between the incumbent and the entrant final goods sellers is sufficiently small, and (iii) the marginal cost difference between the incumbent and the entrant developing-country producers is sufficiently high. We also show that patent protection in the developing country always creates higher developing-country welfare if no developing-country firm enters the final goods market. We also discuss the implications of Bertrand competition on our results.

A nonparametric analysis of multi-product oligopolies

We develop revealed preference tests for models of multi-product oligopoly, building on the work in Carvajal et al. (Econometrica 81(6):2351–2379, 2013). We analyze a Cournot model with multiple goods and show that it has testable restrictions when at least one good is produced by two or more firms. We also develop a revealed preference test for Bertrand oligopoly in a setting where each firm produces a single differentiated good, and these goods are potentially substitutes for each other. Our tests require qualitative assumptions on the shape of the demand curves and (in the Bertrand case) their evolution across observations, but they do not rely on the estimation of market demand.     

The Final Incidence of Australian Indirect Taxes

The Australian Bureau of Statistics provides a breakdown by industry of the revenue collected from each of the major indirect taxes in Australia. This information does not show who bears the ultimate burden of indirect tax as each industry may pass on its initial burden to others. Thus, the burden of the tax may be passed on round by round to indirect business purchases and final demand until the total burden of the tax is passed onto the final consumer. Using a method to derive final indirect tax incidence developed from earlier studies, the final incidence of a selection of indirect taxes in Australia is presented. The major innovation is to include the use of margin industries in the initial flows of the input-output matrix ensuring that taxes on inputs to margin services are fully passed forward onto the good or service that the consumer purchases. It is found that many goods and services that are initially exempt from the main indirect taxes, such as the wholesale sales tax, have significant effective tax rates once taxes on inputs to industry are taken into account.

Spillovers through backward linkages from multinationals: Measurement matters!

We argue that the measures of backward linkages used in recent papers on spillovers from multinational companies are potentially problematic, as they depend on a number of restrictive assumptions, namely that (i) multinationals use domestically produced inputs in the same proportion as imported inputs, (ii) multinationals have the same input sourcing behaviour as domestic firms, irrespective of their country of origin, and (iii) the demand for locally produced inputs by multinationals is proportional to their share of locally produced output. We discuss why these assumptions are likely to be violated in practice, and provide alternative measures that overcome these drawbacks. Our results, using plant level data for Ireland, clearly show that the choice of backward linkage measure and thus, the assumptions behind it, matters greatly in order to draw possible conclusions regarding the existence of foreign direct investment (FDI)-related spillovers. Using the standard measure employed in the literature we fail to find robust evidence for spillovers through backward linkages. However, when we use alternative measures of backward linkages that relax assumptions (i)–(iii), we find robust evidence for positive FDI backward spillover effects.

Trade liberalization and Firms’ export performance in China: Theory and evidence

The focus of the literature surrounding trade liberalization has recently shifted from trade liberalization in imported final goods to studying the effects of trade liberalization in imported intermediate inputs. This emphasis fits very well the trade liberalization experience of China following its accession to the WTO in 2001. In this paper, we build a multi-sector heterogenous-firm model with trade in both intermediate goods and final goods, and we ask: How do final-goods producers respond to trade liberalization in imported inputs? Do they respond differently across sectors? How do firms respond differently to trade liberalization in imported-outputs instead? We separate the total effect of trade liberalization into those caused by inter-sectoral resource allocation (IRA) and by within-sector selection of firms according to productivity (which we call Melitz selection effect). It is the IRA effect that gives rise to differential impacts of trade liberalization in different sectors. These impacts include changes in the probability of entry into the export market, the fraction of firms that export and the share of export revenue. To test our hypotheses, we carry out both quantitative analysis and empirical analysis by using Chinese firm-level data. The results are consistent with our theoretical predictions.     

Data Games: Sharing Public Goods with Exclusion

A group of firms decides to cooperate on a project that requires a combination of inputs held by some of them. These inputs are non‐rival but excludable goods, i.e., public goods with exclusion such as knowledge, data or information, patents or copyrights. We address the question of how firms should be compensated for the inputs they contribute. We show that this problem can be framed within a cost sharing game for which the Shapley value comes out as a natural solution. The main result concerns the regular structure of the core that enables a simple characterization of the nucleolus. However, compared to the Shapley value, the nucleolus defines compensations that appear to be less appropriate in the context of data sharing. Our analysis is inspired by the problem faced by the European chemical firms within the regulation program REACH that requires submission by 2018 of a detailed analysis of all the substances they produce, import, or use.
