Trade liberalization,forward‐looking firms,and welfare

We set up an oligopolistic model with two exporting firms selling to a third market to investigate the welfare implications of trade liberalization when the exporting firms are forward‐looking. The results show that with cost asymmetry trade liberalization encourages the exporting firms to engage in tacit collusion, which may not only be detrimental to the domestic welfare, but also to the consumer surplus of the importing country. Moreover, we find that tacit collusion is less sustainable if the government of the importing country imposes a lower (higher) tariff on the more (less) efficient exporting firm. If a nonforward‐looking or a forward‐looking cost‐efficient domestic firm exists in the importing country, then trade liberalization also encourages tacit collusion.     

INTERNATIONALIZATION STRATEGIES IN OLIGOPOLY WITH HETEROGENEOUS FIRMS

This paper examines the foreign direct investment (FDI) versus exports decision of foreign oligopolistic firms under cost heterogeneity. An additional motivation for firms to invest abroad is the technological sourcing via spillovers, which flow from the host more efficient firm to foreign less advantaged firms. For intermediate values of the set‐up costs associated with FDI entry, it is shown that foreign firms choose opposite entry strategies. An equilibrium where the less efficient foreign firm exports whereas the more efficient invests is more likely to happen when foreign firms become more heterogeneous, the larger the trade costs and not too big oligopolistic profitability. Interestingly, the opposite may also be an equilibrium thus finding that the more efficient firm does not choose to invest, a result that emphasizes the relevance of the strategic setting under consideration. The latter result identifies a market failure since welfare in the host market is higher when both firms undertake FDI; a finding that calls attention to how appropriate are host government policies towards internationalization strategies.     

PRICE AND QUANTITY COMPETITION WITH ASYMMETRIC COSTS IN A MIXED DUOPOLY: A TECHNICAL NOTE

We consider a mixed duopoly in which private and public firms can choose to strategically set prices or quantities when the public firm is less efficient than the private firm. Thus, even with cost asymmetry, we obtain exactly the same result (i.e., Bertrand competition) of Matsumura and Ogawa (2012) if Singh and Vives’ (1984) assumption of positive primary outputs holds. However, compared to endogenous determination of the type of contract without cost asymmetry, our main finding is that in the wider range of cost asymmetry, different type(s) of equilibrium related to or not related to the limit‐pricing strategy of the private firm can be sustained. Thus, when considering an implication on privatization, we may overestimate the welfare gain of privatization because Cournot competition takes place after privatization even though cost asymmetry exists between firms. While the result of Matsumura and Ogawa (2012) holds true if the goods are complements, we find the novel results in the case of substitutes.

When imperfect collusion is profitable

This paper studies cartel stability under the assumption that member firms can choose intermediate degrees of collusion as well as the joint-profit-maximizing solution in determining the quota to be produced by each firm. After showing that firms can increase the number of participants by decreasing the degree of collusion, I prove that individual members' profits are maximized when firms choose a (possibly low) degree of collusion such that all firms in the industry want to take part in the cartel. More precisely, if the number of firms in the industry is four or less, then all of them want to take part in the cartel even if the maximum degree of collusion is chosen (i.e., the monopoly output is produced); if the number of firms is greater than four, firms will still create an industry-wide cartel but they will produce a higher quantity than the monopoly output.     

Adverse selection,commitment and exhaustible resource taxation

This paper studies the contractual relationship between a government and a firm in charge of the extraction of an exhaustible resource. Governments design taxation scheme to capture resource rent and they usually propose contracts with limited duration and possess less information on resources than the extractive firms do. This article investigates how information asymmetry on costs and an inability to commit to long-term contracts affect tax revenue and the extraction path. This study gives several unconventional results. First, when information asymmetry exists, the inability to commit does not necessarily lower tax revenues. Second, under asymmetric information without commitment, an efficient firm may produce during the first period more or less than under symmetric information. Hence, the inability to commit has an ambiguous effect on the exhaustion date. Third, the modified Hotelling's rule is such that an increase in the discount factor does not necessarily reduce the first-period extraction.     

Minimum safety standards with asymmetric safety costs

We explore the welfare effect of minimum safety standards, focusing on the case where duopoly firms are asymmetric in that they have different safety effort costs. If duopoly firms are symmetric, they do not provide enough safety to be socially efficient, and so imposing minimum safety standards can resolve this problem. We show, however, that imposing minimum safety standards may reduce the social welfare when there is a large asymmetry in the safety effort costs. In the unregulated equilibrium, the high-cost firm’s safety effort is smaller than that of the low-cost firm, and the high-cost firm is more likely to provide a larger safety effort than is needed to have a socially efficient level with larger asymmetry in the safety effort costs. If safety standards raise the high-cost firm’s safety effort, both firms’ safety efforts may end up further away from the socially efficient level: the low-cost firm reduces its safety effort when the rival’s effort increases because safety efforts are strategic substitutes.     

Collusive behaviour under cost asymmetries when firms compete in supply functions

This paper investigates the effect of cost heterogeneity in cartel formation and its sustainability over time when firms compete in supply functions under uncertainty. We find that cartel formation and collusion sustainability are hindered as cost differences increase. Efficiency losses caused by collusive behaviour are shown to decrease as asymmetry increases and, therefore, welfare losses also decrease. We compare our results with those obtained under Cournot and Bertrand competition.     

WAGE BARGAINING AND MERGER INCENTIVES WITH ASYMMETRIC COSTS

This paper examines how wage bargaining within each firm influences the relationship between an equilibrium ownership structure and the most preferred ownership structure from the viewpoint of social welfare, in a unionized oligopoly of asymmetric firms with respect to productivity of capital. We consider the merger incentive of each firm’s owner when the wage level is determined through bargaining between the firm’s owner and union. We derive a condition for both the degree of cost asymmetry among existing firms and the relative bargaining power of each firm’s owner to her/his union such that each ownership structure can be observed in equilibrium. We also show that although the two types of ownership structures with the merger involving the least efficient firm can be equilibria and socially optimal, these structures are observed only when both the degree of cost asymmetry and the relative bargaining power of each firm’s owner are moderate. Finally, we analyse the relationship among the cooperative game approach employed in this paper and two non‐cooperative merger formation approaches, and examine the robustness of the results obtained in this paper against the change in the assumption regarding each firm’s cost function.     

‘To sell or not to sell’: Licensing versus selling by an outside innovator

We study various modes of technology transfer of an outside innovator in a spatial framework when the potential licensees are asymmetric. In addition to different licensing options, we also look into the option of selling the property rights of innovation and find the optimal mode of technology transfer. For licensing we find the optimal policy is to offer pure royalty contracts to both licensee firms when cost differentials between the firms are relatively small compared to the transportation cost, otherwise offer a fixed fee licensing contract to the efficient firm only. Interestingly, we show the innovator is always better-off selling the innovation to any one of the firms who further licenses it to the rival firm. The result holds irrespective of the size of the innovation (drastic or non-drastic) and the degree of cost asymmetry between the licensees. Social welfare is greater under selling than licensing.     

Cartels in the unidirectional Hotelling model

We study the impact of space on perfect collusion sustainability within the unidirectional Hotelling model where the firms are constrained to move to the left. We obtain that when the firm that located to the left of the Hotelling segment has the greater incentive to deviate, the distance between the firms has a negative impact on the capability of the firms to sustain the collusion in equilibrium. On the other hand, when the firm that located to the right has the greater incentive to deviate, greater spatial distance makes the collusion easier to sustain in equilibrium. These results substantially differ from the bidirectional Hotelling model.     

Is capital a collusion device?

Summary. We examine how irreversible capital reduces the possibility of a duopoly to sustain implicit collusion by grim strategies, when the product is homogenous and firms compete in quantities. Compared with the case of reversible capital, there are two countervailing effects: Deviation from an existing collusion is less attractive, because capital once installed causes costs forever. But the punishment will also be less severe due to the high capacity the deviating firm can build before punishment starts. The last effect dominates, meaning that the commitment value of capital is negative for all firms. If capital is irreversible, collusion breaks down for realistic magnitudes of interest rates.

Duopoly models with a joint capacity constraint

The paper proposes a two-stage mixed duopoly model of exhaustible resource market where at the first stage the government decides on the degree of privatization of public firm and at the second stage the public and private firms decide simultaneously on the two-period extraction paths. It is demonstrated that if the two firms have symmetric technologies with increasing marginal extraction costs and the same resource stocks, then neither full nationalization of any of the two firms nor full privatization will be socially desirable. It is shown that the presence of a semi-public firm improves intertemporal allocation of the fixed resource stock. Thus, partial privatization is optimal even under exogenously fixed total outputs of each firm. For asymmetric cost case, when the public firm is less efficient than the private firm, we derive the conditions under which full nationalization or full privatization is optimal.     

Self‐protection? Antidumping Duties,Collusion, and FDI*

It is well established that the threat of antidumping duties can help sustain collusion between a foreign firm and its domestic counterpart. However, when the foreign firm is a multinational with a subsidiary in the domestic country, that subsidiary can undermine efforts for protection, thereby diminishing the threat of duties that would otherwise sustain collusion. Accordingly, we show that the multinational may choose to submit to a tariff even under collusion since evidence indicates that duties are more difficult to remove than initiate. In this way, it is possible to obtain a greater degree of commitment, although it comes at a cost. Nevertheless, we prove that this can be a more profitable strategy than those previously explored. Thus, a parent firm may instruct its subsidiary to support duties against the parent. In fact, we find several cases where subsidiaries of multinationals have indeed filed for protection from their own parents.     

Risk Preferences and Gender Differences in Union Membership in Late Nineteenth-Century Swedish Manufacturing

Women are generally seen as less inclined to join trade unions. This study matches firm–worker data from the Swedish cigar and printing industries around 1900 and examines information on men and women holding the same jobs; such data are rare but important for understanding gender gaps. The results explain the gender gap in union membership among compositors, but not among cigar workers. Differences in union membership varied considerably across firms, with the largest differences found in low-union-density cigar firms where indirect costs (that is, uncertainty and risk) accrued in particular to women workers. The lack of gender differences in mutual aid membership indicates that women were not hard to organize but avoided organizations associated with greater risk for employer retaliation and uncertain returns according to a cost–benefit analysis.     

政企合谋、环境规制与企业全要素生产率*

本文利用中国工业企业数据库和地级市层面的企业治污投资数据构建了一个2003—2007年的面板,实证检验了环境规制对企业全要素生产率的影响以及政企合谋在背后的作用。实证结果表明,用企业治污投资占工业增加值比重衡量的环境规制强度每上升1%,企业当期的生产率下降约1%。当政企合谋可能性上升时,环境规制对企业生产率的边际影响在减弱,说明政企合谋带来的监管放松和处罚不力弱化了环境规制对合谋企业生产率的影响。本文的政策启示在于中央政府应加强环保领域统一执法,破解囚徒困境式的环境规制。同时,本文的发现为环保机构监测监察执法垂直管理制度改革提供了合理性依据。     

Regulation through a revenue contest

This paper proposes a mechanism for the regulation of duopolies a revenue contests among the firms. Under the mechanism, the firm with the lower revenue is to pay a penalty to the firm with the higher revenue proportional to the difference between their revenues. In a homogenous good Cournot duopoly with convex cost and demand functions, the mechanism implements the optimal outcome when the firms have symmetric costs. When one firm is more efficient, the mechanism leads to increased social surplus under a large set of parameters. We also consider extensions that involve cost uncertainty, repeated games and differentiated goods.     

Mergers,cartels and leniency programs: The role of capital stocks

This paper examines the impact of mergers on collusion, depending on the endowment of capital assets among firms. We show that mergers render collusion easier to sustain when an asymmetric capital stock is combined with less-efficient insiders, due to more symmetric conditions and tighter incentive constraints. Moreover, the model allows us to determine an optimal threshold of asymmetry between insiders and outsiders such that mergers have pro-competitive effects; we compare this value with that which would generate perfect symmetry between firms after the merger.     

Asymmetric cross-price effects and collusion

Asymmetries in cross-price elasticities have been demonstrated by several empirical studies, but received little attention by the theoretical literature. In this paper we study from a theoretical stance how introducing asymmetry in the substitution effects influences the sustainability of collusion. We first characterize the equilibrium of a linear Cournot duopoly with substitute goods, and consider substitution effects which are asymmetric in magnitude. Since the two goods are asymmetric strategic substitutes, the production decisions are driven by the firm which is relatively less influenced by the rival. We then study partial collusion using the folk theorem's solution concept. Our main result shows that the interval of quantities supporting collusion in the asymmetric setting is always smaller than the interval in the symmetric benchmark. The asymmetry in the substitution effects thus hinders collusion.     

Dissertation abstract: Essays on pricing in experimental duopoly markets

This dissertation comprises three independent essays that analyze pricing behavior in experimental duopoly markets. The first essay examines whether the content of buyer information and the timing of its dissemination affects seller market power. We construct laboratory markets with differentiated goods and costly buyer search in which sellers simultaneously post prices. The experiment varies the information on price or product characteristics that buyers learn under different timing assumptions (pre- and post-search), generating four information treatments. Theory predicts that price information lowers the equilibrium price, but information about product characteristics increases the equilibrium price. That is, contrary to simple intuition, presence of informed buyers may impart a negative externality on other uninformed buyers. The data support the model's negative externality result when sellers face a large number of robot buyers that are programmed to search optimally. Observed prices conform to the model's comparative statics and are broadly consistent with predicted levels. With human buyers, however, excessive search instigates increased price competition and sellers post prices that are significantly lower than predicted. The second essay uses experimental methods to demonstrate the anti-competitive potential of price-matching guarantees in both symmetric and asymmetric cost duopolies. When costs are symmetric, price-matching guarantees increase the posted prices to the collusive level. With asymmetric costs, guaranteed prices remain high relative to prices without the use of guarantees, but the overall ability of guarantees to act as a collusion facilitating device depends on the relative cost difference. Fewer guarantees, combined with lower average prices, suggest that cost asymmetries may discourage collusion. The third essay investigates the effect of firm size asymmetry on the emergence of price leadership in a homogeneous good duopoly. With discounting, the unique subgame-perfect equilibrium predicts that the large firm will emerge as the endogenous price leader. Independent of the level of size asymmetry, the laboratory data indicates that price leadership by the large firm is one of the most frequently observed timings of price announcement. In most cases, however, it comes second to simultaneous price-setting. This tendency to wait for the other firm to announce its price is especially strong when the level of size asymmetry between firms is low. We attribute the lower than expected frequency of price leadership to coordination failure, which is further compounded by elements of inequity aversion.
