Incentives for sabotage in vertically related industries

We show that the incentives of a vertically integrated supplier to “sabotage” the activities of downstream rivals can vary with both the type of sabotage and the nature of downstream competition. Cost-increasing sabotage is typically profitable under both Cournot and Bertrand competition. In contrast, demand-reducing sabotage is often profitable under Cournot competition, but unprofitable under Bertrand competition. Incentives for sabotage can vary non-monotonically with the degree of product differentiation.      

Cross-border mergers in a mixed oligopoly

This paper identifies the unique strategic issues of cross-border mergers in a mixed oligopoly showing that the presence of a welfare maximizing public firm increases the incentive for such mergers. The well-known merger paradox that two-firm mergers are rarely profitable is substantially relaxed in the cases of both linear and convex production costs. The ability to identify profitable two-firm mergers in this context takes on added importance as the recent cross-border merger wave often involved industries with public firms.     

Cross-border mergers and strategic alliances

This paper develops a model with distribution costs to study firm cooperation in forming strategic alliances and mergers, under different types of foreign market entry modes, that is, export or foreign direct investment (FDI). Under both export and FDI, we find that cross-border alliances (mergers) dominate domestic alliances (mergers); and cross-border alliances and mergers are preferred to independence if and only if distribution cost is high. Under export, cross-border alliances are chosen in equilibrium if distribution cost is high. Under FDI and with high distribution cost, cross-border alliances (mergers) are chosen in equilibrium if plant setup cost is low (high).     

Upstream horizontal mergers involving a vertically integrated firm

Journal of Economics - We study upstream horizontal mergers when one of the merging parties is vertically integrated. Under observable contracting in the pre-merger case, we show that such type of...     

Cross-border mergers and acquisitions and the role of trade costs

Cross-border mergers and acquisitions (M&As) have increased dramatically over the last two decades. This paper analyses the role of trade costs in explaining the increase in the number of cross-border M&As. In particular, we distinguish horizontal and non-horizontal M&As and investigate whether trade costs affect these two types of mergers differently. We analyse this question using industry data for 23 OECD countries for the period 1990-2001. Our findings suggest that while in the aggregate trade costs affect cross-border merger activity negatively its impact differs importantly across horizontal and non-horizontal mergers. The impact of trade costs is less negative for horizontal mergers, which is consistent with the tariff-jumping argument.     

Location of vertically linked industries: agglomeration versus comparative advantage

This paper analyses the effects of trade liberalisation on the location of manufacturing firms that are vertically linked and differ in factor intensities. I extend the new economic geography literature, by embedding a model with vertical linkages within a Heckscher-Ohlin framework. I show that lower trade costs can lead to an agglomeration of all upstream and downstream firms in one country, even when they differ in factor intensities. These industrial location patterns do not always lead to factor price convergence; and may result in an increase in returns to both factors in the country where the agglomeration locates.     

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.     

R&D policy in a vertically related industry

In this paper, we analyze the effectiveness of public policy aimed to stimulate business-performed R&D in a vertically related market. We examine the role of an R&D active upstream supplier in a four-stage R&D model, where we incorporate public funding. The considered policy instrument is direct funding of firms’ R&D efforts. We calculate the optimal policies and show that they have a positive impact on firms’ R&D investments. From a welfare point of view, it is optimal to differentiate the subsidy rates between the upstream and the downstream markets. Competition in the product market leads to a higher subsidy rate to the upstream supplier than to the downstream firms. When concentration is high in the downstream market, the optimal solution is an R&D subsidy for these firms, otherwise the optimal solution is an R&D tax for the downstream firms.     

Upstream and downstream pollution taxations in vertically related markets with imperfect competition

When two markets are vertically related, the government can control pollution at the upstream as well as the downstream market levels. This paper employs the stylized model of input price discrimination and compares the effectiveness of upstream and downstream pollution taxations. We consider the situation in which downstream firms have heterogeneous abatement technologies and an upstream monopolist performs input price discrimination against them. In order to mitigate pollution, the government imposes input tax on the intermediate inputs and emission tax on the pollutant. We show that the degree of input price discrimination decreases with a rise in the input tax and increases with a rise in the emission tax. We further examine the effect of a green tax reform in which the government changes the source of taxation from input tax to emission tax. We argue that although this green tax reform may reduce the tax revenue of the government, it will certainly increase social welfare.      

Ranking the optimum tariff and the maximum revenue tariff in vertically related markets

This paper firstly shows that in a vertically related industry with either domestic upstream monopolist or foreign upstream monopolist, when the upstream firm adopts uniform input pricing, the optimum-welfare tariff is higher than the maximum-revenue tariff, if the number of foreign competitors is sufficiently large. Secondly, when domestic upstream monopolist adopts discriminatory input pricing, the maximum-revenue tariff is higher than the optimum-welfare tariff. Thirdly, when foreign upstream monopolist adopts discriminatory input pricing, the optimum-welfare tariff will exceed the maximum-revenue tariff if the sizes of domestic and foreign firms become more unequally distributed.     

Upstream mergers,downstream mergers,and secret vertical contracts

In an industry characterized by secret vertical contracts, we consider a benchmark case where two vertical chains exist, with two upstream manufacturers selling to two downstream retailers, and show that the equilibrium prices are independent of whether upstream or downstream firms have all the bargaining power. We then analyse two alternative mergers, and show that a downstream merger (which gives the downstream monopolist all the bargaining power) is more welfare detrimental than an upstream merger (which gives the bargaining power to the upstream monopolist). We also show that downstream and upstream mergers have the same effects when contracts are observable.     

Profitability of mergers in food manufacturing

Two issues are examined. The statistical significance of a number of socio-economic factors that affect the level of charitable giving are evaluated. Family wealth and age of the head of household tend to be significant determinants of charitable giving, regardless of whether it is to all charities or to religious charities only. Such is not the case for the price of giving; for instance, the price of giving is an important determinant of all charitable contributions, but almost non-existent as a determinant for religious donations. Results such as this suggest that changes in marginal tax rates prompted by a switch to a tax credit as a substitute for a deduction, and hence a change in the price of giving, may have virtually no impact on contributions to religious organizations but may affect conntributions to other charitable organizations. The extent to which some socio-economic factors changed in relative importance as determinants of charitable giving from 1982 to 1986 is also reviewed.     

Horizontal mergers and product quality

We study the effects of a horizontal merger when firms compete on price and quality. In a Salop framework with three symmetric firms, several striking results appear. First, the merging firms reduce quality but possibly also price, whereas the outside firm increases both price and quality. As a result, the average price in the market increases, but also the average quality. Second, the outside firm benefits more than the merging firms from the merger, and the merger can be unprofitable for the merger partners, i.e., the “merger paradox” may appear. Third, the merger always reduces total consumer utility (though some consumers may benefit), but total welfare can increase due to endogenous quality cost savings. In a generalized framework with n firms, we identify two key factors for the merger effects: (i) the magnitude of marginal variable quality costs, which determines the nature of strategic interaction and (ii) the cross‐quality and cross‐price demand effects, which determines the intensity of price relative to quality competition. These findings have implications for antitrust policy in industries where quality is a key strategic variable for the firms.     

Monopolization through endogenous vertical mergers

While endogenous merger analysis has been applied to horizontal mergers, the thrust of vertical merger analysis has been based on exogenous mergers. The goal of this paper is to analyze endogenous vertical mergers. I consider a market structure with a downstream monopolist and an oligopolistic upstream industry. The downstream monopolist chooses to buy a certain number of the upstream firms. Mergers are endogenous, in the sense that the bids made by the downstream firm must be accepted by each of the integrated upstream firms, and must not exceed the increase in the profits of the downstream firm. It is shown that the unique equilibrium is complete monopolization: the buyer buys all the firms in the upstream industry. This result is consistent with the result that vertical mergers are profitable. However, it is in contrast with horizontal endogenous mergers, where complete monopolization is generally not an equilibrium.     

Common pool problems in voluntary municipal mergers

We analyze free-riding behavior of Finnish municipalities prior to voluntary municipal mergers. The merger process creates a temporary common pool problem, because of a delay from the initial decision to the actual merger during which municipalities stay autonomous. Using a difference-in-differences strategy, we find that the stronger free-riding incentive a municipality faced the more it increased its debt and spent its cash reserves. These funds were spent mostly on investments and current expenditures.     

Endogenous mergers and cost heterogeneity

This study analyses early retirement pathways for Norwegian male and female workers, applying a multinomial logit model to a data set covering more than 10500 employees, ages 56-61, in 1989. The aim is to analyse the transition to different destinations, i.e. disability pension, unemployment benefits, and out of the labour force, in the period 1989-1995. Both family characteristics, expected income in different end-states, and push factors, such as industry attachment and local unemployment, are important for the early retirement process. Findings also indicate that there are several gender differences. The explanatory variables have different effects on the different exit routes for males as well as for females. The hypothesis that disability and unemployment are exchangeable pathways into early retirement is rejected.     

Partial ownership and cross-border mergers

Partial ownership can be used as a screening device by a foreign firm which wants to merge with a local firm whose productivity is private information. As partial ownership is confined to sharing future merger profits, it cannot achieve complete separation in all cases but improves expected merger gains also in an equilibrium which is not fully separating. Without partial ownership, the foreign firm potentially discriminates against high productivities. In a pooling equilibrium with partial ownership, however, it will potentially discriminate against intermediate productivities.     

A pre-emption model of mergers

This paper studies the paradox of the value destroying mergers in a sequential negotiation model in which the synergy accrued from the mergers is private information. This study shows that in a simultaneous competitive bidding process, the winner’s curse of overpaying rarely occurs but may arise in the target firm initiated sequential negotiations; and if the merger is successful then the outcome is never value destroying for the combined firm. Thus the acquirer’s overpayment cannot be considered as the ‘winner’s curse’ that results from the post-announcement competitive bidding but rather than the result of the target’s strengthened bargaining power in the sequential negotiations. The implications and intuition of such value-destroying mergers thus differ substantially from that of existing pre-emptive mergers and acquisitions models that use a simultaneous bidding mechanism. The results also imply that the ‘acquisition premium’ accrues to the target firms.
