Wage bargaining,productivity growth and long-run industry structure

This paper studies the innovation dynamics of an oligopolistic industry. The firms compete not only in the output market but also by engaging in productivity enhancing innovations to reduce labor costs. Rent sharing may generate productivity dependent wage differentials. Productivity growth creates intertemporal spillover effects, which affect the incentives for innovation at subsequent dates. Over time the industry equilibrium approaches a steady state. The paper characterizes the evolution of the industry's innovation behavior and its market structure on the adjustment path.     

Vertical foreign direct investment: Make,buy, and sell

According to conventional wisdom, multinational enterprises (MNEs) undertake vertical FDI to take advantage of cross‐border factor cost differences and source inputs from abroad at better terms. However, recent empirical studies document many instances in which intrafirm trade between parent firms and their vertically related foreign affiliates is absent. We provide theoretical support for these findings, demonstrating that a firm can engage in vertical FDI to exploit its intangible assets in another country and improve its input sourcing terms domestically by enhancing its cross‐threat. Furthermore, we show that the welfare implications of vertical FDI on the home and host country are neither always positive nor aligned.     

Foreign direct investment in vertically related markets

We study an MNE's choice of FDI mode in a vertically related market with local input sourcing. We show how the market's vertical structure and trading features affect this choice. An MNE's incentives to expand through cross-border acquisition rather than through greenfield investment are stronger in markets with higher upstream bargaining power, upstream concentration and unobservable contract terms. The opposite holds in markets in which wholesale price contracts, instead of two-part tariffs, are used. Our welfare analysis suggests that the host country should not always welcome FDI and should discourage FDI through acquisition.     

Location for Foreign Direct Investment in Vertically Related Markets

This paper studies a multinational enterprise's (MNE's) location decision in a vertically related market with endogenous vertical technology transfer (VTT). We show that, even though VTT is more costly in a less developed country, an MNE can transfer more technology there than in a developed country (DC). When the opposite occurs, the MNE sometimes locates in a DC where, although it faces stronger competition, it obtains the input at better terms. Therefore, by arguing that the MNE's decision can be crucially affected by the upstream market's outcomes, an alternative explanation is provided for the commonly observed foreign direct investment (FDI) in DCs.     

Timing of technology adoption and product market competition

This paper examines how product market competition affects firms' timing of adopting a new technology, as well as whether the market provides sufficient adoption incentives. It demonstrates that adoption dates differ, not only among symmetric firms, but also among markets with different market features. More specifically, technology adoption can occur earlier in a market with Cournot competition than in a market with Bertrand competition. It can also occur earlier in a market in which goods are not too close substitutes. Therefore, this paper shows that competition toughness does not always reinforce adoption incentives. When goods are sufficiently differentiated, adoption occurs later than is socially optimal.     

Endogenous protection of R&D investments

Abstract .  We examine firms' incentives to protect their non-cooperative R&D investments from spilling over to competitors. We show that, contrary to findings in most of the literature, the lack of full appropriability can lead to an increase in R&D investments. Consequently, as long as the R&D spillovers are not too strong, firms decide to let their R&D knowledge flow. Since, as we show, welfare is higher when R&D spillovers are present, it follows that public policies that promote the dissemination of technological knowledge could be welfare-enhancing.     

Vertical Contracts and Downstream Entry*

We study the implications of different contractual forms in a market with an incumbent upstream monopolist and free downstream entry. We show that traditional conclusions regarding the desirability of linear contracts radically change when entry in the downstream market is endogenous rather than exogenous. By triggering more entry than two-part tariffs, wholesale price contracts can generate higher aggregate output, consumer surplus, and welfare. In light of this, the upstream monopolist may prefer to trade with wholesale price contracts as well as to give up part of its bargaining power when it is high.     

Upstream Mergers,Downstream Competition,and R&D Investments

In this paper, we provide an explanation for why upstream firms merge, highlighting the role of R&D investments and their nature, as well as the role of downstream competition. We show that an upstream merger generates two distinct efficiency gains when downstream competition is not too strong and R&D investments are sufficiently generic: The merger increases R&D investments and decreases wholesale prices. We also show that upstream firms merge unless R&D investments are too specific and downstream competition is neither too weak nor too strong. When the merger materializes, the merger‐generated efficiencies pass on to consumers, and thus, consumers can be better off.     

Manufacturer Mergers and Product Variety in Vertically Related Markets

We study the incentives of final product manufacturers to introduce new products into the market and the impact of a manufacturer merger on them. We show that when manufacturers distribute their products through multi-product retailers, a manufacturer merger, although it leads to an increase in the wholesale prices, it can enhance product variety. The merger induced product variety enhancement though arises only when vertical relations are present: when manufacturers sell directly their products to consumers, a merger never results in more product variety. Still, both with or without vertical relations, a manufacturer merger hurts consumers and decreases welfare.
