Bilateral Agreements in a MultiFirm Industry: Technology Transfer and Horizontal Merger

The paper studies the profitability of technology transfer and horizontal merger between two asymmetric firms in a multifirm Cournot oligopoly. If there is only one technologically advanced firm and one or many technologically backward firm(s), a profitable technology deal between two asymmetric firms exists if and only if the collaborating firms are "close" in terms of their initial technology levels. With more than one advanced firm such a technology deal is "always" profitable. Contrary to that, a profitable bilateral horizontal merger occurs if and only if the gap of technologies between the two partners is larger than a critical level. The paper also studies the relative profitability of these two bilateral arrangements.     

HORIZONTAL MERGERS: A SOLUTION OF THE INSIDERS' DILEMMA

We show that in a three‐firm infinitely repeated Cournot game, there exists a stick and carrot strategy equilibrium in which an exogenous bilateral horizontal merger is profitable and the incentive to remain out of the merger disappears. In this sub‐game perfect equilibrium, the merged entity produces the duopoly quantity and the outsider limits its production to half the duopoly quantity. Our stick and carrot strategy entails that the merged entity threatens to produce twice the triopoly quantity for two periods if the outsider does not produce half the duopoly quantity. In this equilibrium, the aggregate price remains high enough to make the merger profitable for the insiders. Also, the quantity produced by the outsider is sufficiently low to eliminate the difference between the profit of the outsider and the merging firm.     

Managerial firms’ profitability,unions, and environmental taxes

This article examines how determining an optimal environmental tax in a Cournot duopoly with unionized labour markets and managerial firms departing from the strict profit-maximization. It is shown that firm-specific monopoly unions that set wages (1) reduce both the environmental tax and environmental damage and (2) counterintuitively, increase firms’ profitability when the abatement technology is not too “efficient”, and the public evaluation of environmental quality is sufficiently high. Within this framework, the work also develops the endogenous game played by firms that must choose between sales delegation (SD) and profit-maximization. Results show that the SD contract always emerges as the unique, deadlock sub-game perfect Nash equilibrium, thereby solving the (prisoner's) dilemma emerging in the related existing literature assuming a competitive labour market.     

Licensing versus assignment: Innovation transfer in an asymmetric duopoly

Suppose that the relatively inefficient firm in an asymmetric duopoly market develops a nondrastic process innovation. To maximize returns on the innovation, the innovator must determine the most lucrative commercial policy. Should it be in‐house exploitation, or licensing or assignment? It turns out that the innovator never uses innovation exclusively. The choice of licensing or assignment depends on the size of the initial cost difference. When the initial cost difference is relatively small, the innovator would resort to licensing, whereas when there is a significant initial cost gap, the innovator would rather assign the property rights of the innovation to the rival. In the case of assignment, the assignee may license the innovation back to the assignor. With the option of reverse licensing, an assignment will always be more profitable than (direct) licensing. Interestingly, if the initial cost gap were sufficiently large, the innovator would exit the market postassignment, and thus act as an outside nonoperating licensor.     

International asymmetric R&;D rivalry and industrial strategy

Profit-sharing licensing is quite a common business practice. In a Cournot duopoly model, we showed that if not subject to any restrictions this kind of technology for equity deal would lead to a decline in industry output and hurt consumers. To avoid the industry output contraction and protect the interests of consumers, the government can intervene in licensing by requiring that the profit-sharing rate specified by a licensing contract should not exceed the percentage difference of involved firms’ equilibrium outputs before licensing.     

Collusion in Differentiated Duopolies with Quadratic Costs

The analysis of collusion in infinitely repeated duopoly games has generally assumed that marginal cost is constant, but this note uses quadratic costs (linear marginal costs) to compare the sustainability of collusion under Bertrand and Cournot duopoly with differentiated products. It is shown that when marginal costs are sufficiently increasing in output, then it is always easier to sustain collusion under Cournot duopoly than under Bertrand duopoly for any degree of product substitutability.

Mixed duopoly, cross-ownership and partial privatization

This paper investigates the effects of cross-ownership on optimal privatization, and vice-versa, in mixed duopoly. It shows that cross-ownership is profitable to the private firm only if the level of privatization of the public firm is sufficiently high. In equilibrium, cross-ownership does not take place even if there is partial privatization. However, the possibility of cross-ownership significantly limits the socially optimal level of privatization in most of the situations. Moreover, it demonstrates that full nationalization is socially optimal, in case of sufficiently convex identical cost functions and homogeneous goods. These results have strong implications to both divestment and competition policies.     

Choosing Price or Quantity? The Role of Delegation and Network Externalities in a Mixed Duopoly

This paper considers a differentiated goods managerial mixed duopoly composed of one social welfare‐maximising public firm and one profit‐maximising private firm. We model the firm choice of the strategic contract. We find that when the strength of network effects is sufficiently strong, the price competition can become the unique equilibrium market structure. Furthermore, we show that there exists an area of the degree of product differentiation and the strength of network effects such that the situation wherein the public firm chooses its price contract whereas the private firm chooses its quantity contract can become the unique equilibrium structure.     

Optimal patent licensing—Two or three-part tariff

We look into technology transfer by an insider patentee in a spatial duopoly model under three types of licensing contracts—(i) two-part tariff with fixed fee and per-unit royalty, (ii) two-part tariff with fixed fee and ad-valorem royalty and (iii) general three-part tariff with fixed fee, per-unit and ad-valorem royalties. Under two-part tariff contracts, the licenser is better off with the per-unit royalty contract but the general contract does better than the other contracts. In contrast to the existing literature, all three licensing contracts may make the consumers worse-off compared to no licensing, with the lowest consumer surplus achieved under the general licensing contract. Welfare under the general licensing contract is equal to the welfare under two-part tariff with ad-valorem royalty and it is higher than the welfare under no licensing but lower than the welfare under two-part tariff with per-unit royalty. Hence, the general three-part licensing contract is privately optimal but not socially optimal. Similar conclusions hold also under a nonspatial linear demand model with differentiated products.     

Strategic timing in R&D agreements

We study the endogenous formation of R&D agreements in a R&D/Cournot duopoly model with spillovers where also the timing of R&D investments is endogenous. This allows us to consider the incentives for firms to sign R&D agreements over time. It is shown that, when both R&D spillovers and investment costs are sufficiently low, firms may find difficult to maintain a stable agreement due to the strong incentive to invest noncooperatively as leaders. In this case, the stability of an agreement requires that the joint investment occurs at the initial stage, thus avoiding any delay. When spillovers are sufficiently high, the coordination of R&D efforts becomes a profitable option, although firms may also have an incentive to sequence noncooperatively their investment over time. Finally, when spillovers are asymmetric and knowledge mainly leaks from the leader to the follower, investing as follower may become extremely profitable, making R&D agreements hard to sustain unless firms strategically delay their joint investment in R&D.     

Optimal contract under brand name collaboration

In an international Cournot duopoly, we determine the optimal contract for a brand name collaboration where the contract consists of fixed-fee and output royalty. We show that the firms always have the incentive for brand name collaboration. However, whether the optimal contract will have positive fixed-fee and positive royalty is not immediate and it depends on the factors such as the transportation cost of exporting and the consumers' initial perception about the products of the firms reflected in the consumers' maximum willingness to pay for the products. Thus, our paper shows that the possibility of brand name collaboration is significantly more than predicted in the existing literature.     

PRICE AND QUANTITY COMPETITION IN A UNIONISED MIXED DUOPOLY: THE CASES OF SUBSTITUTES AND COMPLEMENTS*

We investigate a differentiated mixed duopoly in which private and public firms can choose to strategically set prices or quantities when unions are present. For the case of a unionised mixed duopoly, there exists a dominant strategy only for the public firm that chooses Bertrand competition irrespective of whether the goods are substitutes or complements; there is no dominant strategy for a private firm. Thus, we show that regardless of the nature of goods, social welfare under Bertrand competition is always determined in equilibrium, wherein Bertrand competition entails higher social welfare than Cournot competition. Moreover, our main results hold irrespective of the nature of goods, with the exception that when a sufficiently large parameter of complements is employed, the ranking of a private firm's profit is not reversed, which is in contrast to the standard findings.     

Endogenous Choice of Strategic Contracts in a Mixed Duopoly with Bargaining Over Managerial Delegation Contracts

We revisit the endogenous choice problem of strategic contracts for the public firm and the private firm in a managerial mixed duopoly with differentiated goods. We consider the situation wherein the managerial delegation contracts are determined by maximising social welfare within the public firm, which is equal to the objective function of its owner, and through bargaining over the content of managerial delegation contracts between the owner and manager within the private firm. We show that, in equilibrium, when the manager of the private firm has high bargaining power relative to that of the owner, the public firm chooses a price contract, while the private firm chooses a quantity contract. However, there is no equilibrium market structure under the pure strategic contract class when the manager has sufficiently low bargaining power relative to that of the owner.     

Stackelberg竞争结构中质量提高型创新技术授权和企业兼并

本文基于Stackelberg双头垄断竞争模型,分析比较了质量提高型创新技术拥有企业的技术授权策略和企业兼并。研究结果表明:不论技术拥有企业是市场先行者还是跟随者,其总是偏向于企业兼并,而不会选择固定费用授权方式;如果政府禁止企业的兼并行为,那么当技术拥有企业在市场中是产量跟随者时,其愿意以提成许可方式进行技术授权;从社会福利角度考虑,技术授权可提高社会福利,而企业兼并一般不利于社会福利的提高,只有当创新技术拥有企业是Stackelberg竞争结构中的产量跟随者且其创新规模较大时,企业兼并才可提高社会福利。     

论我国无权处分合同的法律效力

无权处分是指行为人未经授权即以他人所有之物为标的,以其自身的名义与第三人签订合同,并依合同实施了能导致物权设立,转移或消灭的行为。无权处分合同只要符合法律行为的一般生效要件即可生效,就算出卖人欠缺处分权,买受人明知无权处分之事实,均不影响合同之效力。处分权是导致权利变动的核心要件,出卖人欠缺处分权,即使合同有效,也履行了相应的公示行为（动产交付或不动产办理过户登记）,也不能导致物权的变动,但善意取得除外。     

A Model of a Price-setting Duopoly with a Wage-rise Contract

This paper considers a wage-rise contract between a firm and its employees as the firm's strategy, and suggests a wage-rise-contract policy. The policy is a promise by the firm that it will announce a certain output level and a wage premium rate, and if it actually produces more than the announced output level, then it will pay each employee a wage premium uniformly. First, this paper examines the case in which one of two firms unilaterally offers the wage-rise-contract policy by using a two-stage price-setting duopoly model. It is then shown that there exists an equilibrium which coincides with the Stackelberg solution where the firm adopting the policy is the leader. Next, this paper examines the case in which both firms can offer the wage-rise-contract policy in the model. It is then shown that there exists an equilibrium which is more profitable for both firms than in the unilateral case.     

STRATEGIC DELEGATION UNDER UNIONISED DUOPOLY: WHO WILL BARGAIN WITH UNIONS?

This paper investigates the choice of a firm's delegate (either the owner or the manager) bargaining wages and employment with a union under a unionised duopoly. We show that if an owner delegates the task of bargaining to a manager, the owner always compensates the manager for profits by penalising sales, regardless of whether the rival owner delegates or not. Moreover, we show that an owner's decision to delegate the task of bargaining to a manager depends on the incremental benefit of delegating and the cost of hiring a manager. The asymmetric outcome (wherein one owner delegates but the other does not) can occur if there is a sufficiently large disparity of hiring costs between the owners. Finally, we show that the union in an owner‐managed firm always earns more than the union in a managerial firm.     

Herding in delegated portfolio management: When is comparative performance information desirable?

We address the issue of investors’ asset allocation decisions when portfolio management is delegated to an agent. Contrary to predictions from traditional financial theory, it is shown that investors may not induce their manager to allocate funds to the asset with the highest return. Instead they may herd in their asset allocation decision and induce trade in a particular asset, because another manager is trading in it and despite the presence of a more profitable alternative. Doing so allows investors to write an efficiency-improving relative-performance contract. On the other hand, herding leads investors to design wage contracts strategically, resulting in more aggressive and thus less profitable trade in equilibrium. We show that herding occurs, when the cost of information is high, information precision is low and when managers are sufficiently risk averse. Moreover, when investors can decide whether or not to disclose information about their manager's performance, they will not do so.     

Dynamics of technology sharing cartels and industrial structure under a rule of thumb

We analyse the market effects of different degrees of knowledge transfer in a duopoly in which firms act following a rule of thumb. Three regimes are compared: the technology sharing cartels, the duopoly with spillovers, and the proprietary regime. We show the industrial structure evolution of these three regimes under different cost configurations when firms behave myopically, revising their production plan in each period according to the marginal profit previously gained. The analysis is conducted in a discrete setting using numerical simulations of finite difference systems. We show under which conditions knowledge transfer is beneficial to the system and can prevent market monopolisation.
