Endogenous timing game in a mixed duopoly with partial foreign ownership and asymmetric increasing marginal costs

This study examines a timing game in a mixed duopoly wherein public and private firms compete by taking account of the increasing marginal cost of both firms, as well as partial foreign ownership of the private firm. This study finds that if the private firm has a strong cost advantage over the public firm, public leadership is a risk dominant equilibrium irrespective of foreign ownership ratio. This result means that the cost difference between the public and private firms matters in selecting the risk-dominant equilibrium of the timing game. Additionally, if the private firm has only a weak cost advantage over the public firm, then private leadership (public leadership) is the risk dominant equilibrium if the foreign ownership ratio is (not) small.     

Competitive blind spots and the cyclicality of investment: Experimental evidence

We report laboratory experiments investigating the cyclicality of profit-enhancing investment in a competitive environment. In our setting, optimal investment is counter-cyclical when investment costs fall following market downturns. However, we do not observe counter-cyclical investment. Instead, we see much less strategic behavior than our rational investment model anticipates. Our participants exhibit what Porter (1980) terms a competitive blind spot, and heuristic investment models where individuals invest a fixed percentage of their liquidity, or a fixed percentage of anticipated market demand, better fit our data than does optimal investment. We also report a control treatment without cost changes and a treatment with asymmetric investment liquidity. Both of these extensions support our main result.     

Union negotiations,product market cooperation,and profits

Within the context of a unionized duopoly with decentralized Right‐to‐Manage wage negotiations, this paper investigates how different measures of product market cooperation impact firms' profitability. In the presence of exogenous production costs, a classical result in industrial economics is that conjectural derivatives (CD) and conjectural elasticities (CE) lead to similar results, and CE reproduce exactly the same output decision level (and, therefore, profits) of the coefficient of cooperation (CC). These results show that wage bargaining alters those relations; in particular, the equivalence of the CE and CC no longer holds true.

一般需求函数下两级供应链定价博弈研究

研究需求函数为一般需求函数D=f（p）时,供应链中制造商和零售商不合作定价、合作定价的供应链利润。找出了两个充要条件,证明了在制造商和零售商之间不合作定价博弈存在纳什均衡时,该纳什均衡状态的供应链利润劣于合作定价的供应链利润。文中并且给出两个典型需求函数的例子：线性需求函数和柯布一道格拉斯需求函数。分别证明了它们均满足该两个充要条件,印证了所得结论。     

Can privatization be a catalyst for environmental R&D and result in a cleaner environment?

In this paper we explore whether privatization helps to catalyze a firm's environmental research and development (ER&D) and improve environmental quality. By defining ER&D as the effort undertaken by a firm to reduce its pollution per unit of output, we find in a duopoly framework that privatization cannot catalyze both public and private firms’ ER&D efforts simultaneously; it can increase one but decrease the other firm's investment, or it may even lower both firms’ ER&D investments. Moreover, when production causes severe environmental damage, or the imposition of environmental taxes poorly internalize the pollution externality, privatization may result in a poorer environment. For the sake of having a cleaner environment, policy-makers can impose higher environmental taxes on a highly polluting industry when it is being privatized.     

Export,Exchange Rate Risk and Hedging: The Duopoly Case

Abstract. This paper studies a Cournot duopoly in international trade with firms exposed to exchange rate risk. A hedging opportunity is introduced by a forward market on which one firm can trade the foreign currency. We investigate two settings: First, we assume that hedging and output decisions are taken simultaneously. It is shown that hedging is exclusively done for risk‐managing reasons as it is not possible to use hedging strategically. Second, the hedging decision is made before the output decisions. We show that hedging is not only used to manage the risk exposure but also as a strategic device.     

Itemised Deductions: A Device to Reduce Tax Evasion

With direct incentives and sanctions being the most common instruments to fight tax evasion, the theoretical literature has tended to overlook indirect schemes, such as itemised deductions, in which one agent's behaviour affects the likelihood that others will declare their revenue. Itemised deductions provide an incentive for consumers to declare their purchases. This induces a partial shift in the demand from the black market to the legal one, for consumers need a transaction receipt to enjoy the tax deduction. I show that it is possible to increase tax proceeds by choosing a suitable level of itemised deduction, and this, for any level of taxation. Indeed, the cost for the tax authority on the consumers' side is more than compensated for by the extra proceeds generated on the sellers' side.     

Network externalities,transport costs,and tariffs

This article formulates a reciprocal market model of international duopoly with network externalities to reconsider welfare effects of reductions in transport costs and tariffs. Depending on the magnitude of network externalities, we show two possibilities. One of them, which emerges under strong network externalities, illustrates that freer trade unambiguously improves welfare for any initial level of trade barriers. This finding provides an affirmative evaluation of freer trade.     

Sequential technology adoption with asymmetric firms

Abstract

We analyse the incentives and welfare implications of costly technology adoption in a two-period duopoly model where firms have different amounts of capital. We also extend our framework to an open economy set-up and examine the relationship between trade and technology adoption. Our findings are as follows. First, no monotone relationship exists between the threshold cost of adoption and capital shares. Second, an unequal distribution of capital, despite lessening competition, can increase total surplus. Third, trade generally encourages adoption of modern technology unless the share of capital for the adopters is too low.
