Outsourcing versus technology transfer: Hotelling meets Stackelberg

We consider a Hotelling duopoly with two firms $A$ and $B$ in the final good market. Both can produce the required intermediate good, firm $B$ having a lower cost due to a superior technology. We compare two contracts: outsourcing ( $A$ orders the intermediate good from $B$ ) and technology transfer ( $B$ transfers its technology to $A$ ). An outsourcing order is equivalent to building an endogenous capacity and it generates a Stackelberg leadership effect for firm $A,$ which is absent in technology transfer. We show that compared to the situation of no contracts there are always Pareto improving outsourcing contracts (making both firms better off and all consumers at least weakly better off), but no Pareto improving technology transfer contracts. It is also shown that if firm $B$ has a relatively large bargaining power in its negotiations with $A,$ then both firms prefer technology transfer while all consumers prefer outsourcing.     

Bundling strategy and product differentiation

The existing literature shows that a decrease in the degree of substitutability increases a monopoly’s incentive to bundle. This paper in addition takes into account competition in the second product market and then re-examines how intra-brand and inter-brand product differentiations affect the incentive to bundle. In order to formally examine the above conjectures, this research builds up a two-firm, two-product model in which product 1 (monopoly product) is produced only by the bundling firm and product 2 (competing product) is produced by both firms. The analysis shows that under both Bertrand and Cournot competitions the incentive to bundle does not necessarily increase with the degree of intra-brand differentiation, while it strictly decreases with the degree of inter-brand differentiation. Moreover, under Bertrand competition bundling always decreases consumer surplus, but may increase the competitor’s profit and social surplus. Under Cournot competition bundling always reduces the opponent’s profit and social welfare, but may increase consumer surplus.     

Information revelation in competitive markets

This paper analyzes a market with multiple sellers and horizontally differentiated products. We investigate the sellers’ incentives to reveal product relevant information that affects the buyer’s private valuation. The main finding is that if the number of sellers is sufficiently large, there is a unique symmetric equilibrium with full information disclosure. Thus, unlike the results by Lewis and Sappington (Int Econ Rev 35:309–327, 1994) and Johnson and Myatt (Am Econ Rev 93:756–784, 2006) for monopoly, which state that the monopolist reveals either full information or no information, intense competition results in a single extreme with respect to information disclosure. We show that the market is always inefficient, but the magnitude of inefficiency converges to zero at a high rate as competition intensifies.     

Quantity competition vs. price competition under optimal subsidy in a mixed oligopoly

This paper reconsiders the literature on the irrelevance of privatization in mixed markets within which both quantity and price competition are investigated under product differentiation. By allowing for partially privatization of a state-controlled firm, we explore competition under different timings of firms' moves and derive the conditions under which an optimal subsidy allows to achieve maximum efficiency. We show that, irrespective of the mode of competition, while the ownership of the controlled firm is irrelevant when firms play simultaneously, it matters when firms compete sequentially, requiring the leader to be publicly-owned for an optimal subsidy to restore the first-best. The paper also focuses on the extent to which a subsidy is needed to attain the social optimum in the considered scenarios, providing an ordering which highlights the subsidy equivalence between Cournot (Bertrand) private leadership and simultaneous Bertrand (Cournot) under duopoly, and the dominance of the former in oligopoly.     

Consumers’ preferences for a local food product: a real choice experiment

This paper analyses consumers’ preferences for a local food in Spain and assesses their willingness to pay (WTP) using a real choice experiment to mitigate possible hypothetical bias. In particular, preferences for fresh lamb meat were investigated and two attributes evaluated, “locally grown” and the type of lamb meat. Data came from an experiment conducted in Spain during 2009. An error component random Parameter model with correlated errors was used to estimate the effect of the attributes on consumers’ utility and derive their WTP. Results suggest that consumers positively value both attributes and are willing to pay a premium of 9 % price increase for the “locally grown” lamb meat (“Ojinegra from Teruel”) and 13 % price increase for the “Ternasco” lamb meat. If we assume a market where only “Ternasco” lamb meat without indication of the local origin is sold, and then a new “Ternasco” lamb is introduced in the market with the “Ojinegra from Teruel” label, this new local lamb meat would capture 18 % of the market if the package is assumed to be sold at 3.5 \(\hbox {C}\!\!\!\!\!=\) and a 10 % market share if the package is assumed to be sold at 4 \(\hbox {C}\!\!\!\!\!=\) .     

A Re-examination of the Performance of Value Strategies in the Athens Stock Exchange

This study tests the performance of contrarian (value) strategies in the Athens Stock Exchange (ASE) in a recent period of time (2003–8) on the basis of the price to earnings ratios, dividend yields, firm size (market value), market to book ratios, financial leverage ratios, and market beta. Apart from the univariate portfolio analysis, we implement a novel panel data analysis based on the procedure suggested by Pesaran (2004, Econometrica 74:967–1012, 2006) that provides a valid estimation and inference under cross sectional dependence. Our portfolio analysis results highlight for investors in the ASE the superiority of value strategies formed on the basis of stocks with low price-to-earnings, high dividend yield ratios, and low market-to-book ratios. Our panel data analysis results depend on whether or not we correct for the problem of cross-sectional correlation in the regression residuals as suggested by Pesaran’s (Econometrica 74:967–1012, 2006) method. When we correct for this problem, we obtain evidence which support only a negative association between annual stock returns and market-to-book ratios. This may imply to investors that an adoption of a value strategy based on the market-to-book ratio may constitute a safer option compared with the other two alternatives suggested by the portfolio analysis results.     

A note on merger in mixed duopoly: Bertrand versus Cournot

In this note we analyze the incentives to merge in a mixed duopoly if firms compete in prices or quantities. Our model framework mainly follows Barcena-Ruiz and Garzon (J Econ 80:27–42, 2003) who set up the model with quantity competition. We extend their analysis by analyzing the case of competition in prices. Further we compare the incentives to merge with Bertrand and Cournot competition. Comparing quantity with price competition we can show that a merger is more likely with Cournot competition than with Bertrand competition.     

Motivating energy suppliers to promote energy conservation

We examine the design of regulatory policy to induce electric utilities to deliver the surplus-maximizing level of energy efficiency services, $e^{*}$ . The rebound effect (whereby increased energy efficiency stimulates the demand for energy) typically renders revenue decoupling insufficient in this regard. The additional financial incentive required to induce $e^{*}$ is shown to vary with such factors as the prevailing price of energy, the magnitude of the rebound effect, the extent of observable energy efficiency investments, and the utility’s objective.     

Niche products, generic products, and consumer search

We endogenize product design in a model of sequential search with random firm-consumer match value à la Wolinsky (Quart J Econ 96:493–511, 1986) and Anderson and Renault (RAND J Econ 30:719–735, 1999). We focus on a product design choice by which a firm can control the dispersion of consumer valuations for its product; we interpret low-dispersion products as “generic” and high-dispersion products as “nichy.” Equilibrium product design depends on a feedback loop: when reservation utility is high (low), the marginal customer’s match improves (worsens) with more nichy products, encouraging high (low) differentiation by firms. In turn, when firms offer more nichy products, this induces more intense search; depending on search costs, this could raise or lower consumers’ reservation utility. Remarkably, when the match distribution satisfies a hazard rate condition, firm and consumer interests align: equilibrium product design always adjusts to the level that maximizes utility. When this condition is not met, either multiple equilibria (one nichy, the other generic) or one asymmetric equilibrium (generic and nichy firms coexist) can arise; we argue that the former is more likely for common specifications of consumer preferences.     

Product differentiation and competitive pressure

This paper compares the commonly used linear demand model introduced by Bowley (The mathematical groundwork of economics, Oxford University Press, Oxford, 1924) with the specification of Shapley and Shubik (Kyklos 22:30?C44, 1969). The latter has the advantage that aggregate demand does not depend on a parameter that measures the degree of product differentiation. This allows to interpret variations in the degree of product differentiation as changes in competitive pressure because these changes can influence aggregate demand only through changes in equilibrium prices and quantities. The consequences of the alternative specifications are made explicit with two applications. In both cases the different specifications yield substantial changes in important results in industrial economics.     

Product regulations and persistence of profits: OECD evidence

In competitive markets, profits deviating from the norm will not persist for extended periods. If unimpeded, entry and exit of firms should restore profits to competitive levels. This dynamic process is influenced by regulations that temporarily or permanently impede competition. We study how product market regulations (PMR)—as measured by the OECD—affect competition by their impact on the profit persistence (Wölfl et al. in Ten years of product market reform in OECD countries-insights from a revised PMR indicator, 2009, Product market regulation: extending the analysis beyond OECD countries, 2010). To examine profit dynamics, we follow the methodology developed by Mueller (Economica 44(176):369–380, 1977), which measures both the short run persistence of profits and the long run permanent rents. The method can be used to measure: (1) short run transitory rents; (2) long run permanent rents. To this end we use firm level data from 30 OECD countries over the period 1998–2013. Results show that PMR increase the permanent rents of firms but we find no significant effect on short run profit persistence. We conclude that PMR negatively influence competition and increase permanent rents, resulting in misallocation of resources.     

POLITICAL ECONOMY OF STRATEGIC EXPORT POLICY IN A DIFFERENTIATED DUOPOLY*

This paper investigates the effect of a home firm's lobbying on a strategic export policy in a third market with a differentiated duopoly. We focus on its effect on domestic welfare under Bertrand and Cournot competition. Regardless of the mode of competition, the strategic export policy cannot improve domestic welfare in the presence of lobbying if the degree of product differentiation is high or the government is overly concerned with political contribution relative to domestic welfare. Moreover, for the same degree of product differentiation, the lobbying‐induced export policy is more likely to deteriorate domestic welfare relative to free trade under Cournot competition.     

标准专利许可中可变价格的社会福利效应:基于产品差异化的视角

技术标准在产品生产过程中的使用越来越广泛,标准专利许可定价形式问题关系到技术标准所有者和产品生产者的收益,有待拓展研究。通过构建古诺竞争模型,从产品差异化角度对标准专利许可中可变价格形式的社会福利效应进行分析,得到的主要结论为:当产品市场达到均衡,且标准专利许可采用的价格形式是可变价格时,社会总福利随着产品差异化程度的提高而增加,随着差异化产品市场中标准专利使用者数量的增加而增加,随着可变价格中可变费用比率的提高而降低;均衡产量随着产品差异化程度的提高而增大,随着可变价格中可变费用比率的提高而降低;均衡价格与产品差异化程度呈现出倒“U”型关系,临界点为特定的市场规模;标准专利使用者的均衡利润随着产品差异化程度的提高而增大。由此可见,标准专利许可的可变费用比率下降有利于激励技术标准使用者生产更多的差异化产品,提升社会总福利。     

Competition, knowledge, and local government

This paper applies the insights of Austrian economics to an important issue in local political economy. Basic economic theory holds that greater competition produces superior outcomes in private goods markets. The same should be true in the ??markets?? for the output of local government. Brennan and Buchanan (1977, 1980) show that interjurisdictional competition may serve as a potential restraint on the monopoly powers of local Leviathan and Tiebout (1956) shows that it may help lead to the production of efficient quantities of local public goods. However, other potential virtues of competition in the market for local collective goods have been largely ignored. This paper explores those other virtues as well as the neoclassical theoretical foundations of the Tiebout (1956) model, upon which much of this literature is based. This has public policy implications for local governments, which have taken on increased importance given the recent global movement towards more decentralized government.     

A nonparametric analysis of multi-product oligopolies

We develop revealed preference tests for models of multi-product oligopoly, building on the work in Carvajal et al. (Econometrica 81(6):2351–2379, 2013). We analyze a Cournot model with multiple goods and show that it has testable restrictions when at least one good is produced by two or more firms. We also develop a revealed preference test for Bertrand oligopoly in a setting where each firm produces a single differentiated good, and these goods are potentially substitutes for each other. Our tests require qualitative assumptions on the shape of the demand curves and (in the Bertrand case) their evolution across observations, but they do not rely on the estimation of market demand.     

Competition,strategic delegation and delay in technology adoption

This paper examines how strategic managerial delegation affects firms' timing of adoption of a new technology under different modes of product market competition. It demonstrates that strategic delegation has differential impacts on adoption dates under Cournot and Bertrand competitions. Strategic delegation with ‘own-performance’-based incentive schemes always leads to early adoption in markets with Bertrand competition compared to that under no-delegation, but not necessarily so in markets with Cournot competition. It also shows that under strategic delegation with ‘own-performance’-based incentive schemes, adoption occurs earlier (later) in markets with Cournot competition than in markets with Bertrand competition, if the degree of product differentiation is high (low). In contrast, under strategic delegation with ‘relative-performance’-based incentive schemes, adoption dates do not differ across markets with different modes of competition. It also analyses implications of firms' choice over types of managerial incentive schemes on the speed of diffusion of new technology.     

Inferior factor in Cournot oligopoly

The condition for factor inferiority has been well known for a competitive firm facing perfect competition in both product and factor markets. Whether the factor inferiority is observable or not has been unknown for oligopoly facing perfect competition in factor market. We derive a general condition for the factor inferiority in Cournot oligopoly without product differentiation. We derive it on the basis of a novel technique for proving the existence of a unique Cournot equilibrium industry output.     

Downstream mode of competition with upstream market power

In a two-tier oligopoly, where the downstream firms are locked in pair-wise exclusive relationships with their upstream input suppliers, the equilibrium mode of competition in the downstream market is endogenously determined as a renegotiation-proof contract signed between each downstream firm and its exclusive upstream input supplier. We find that the upstream–downstream exclusive relationships credibly sustain the Cournot (Bertrand) mode of competition in the downstream market, when the goods are substitutes (complements). In contrast to previous studies, this result holds irrespectively of the degree of product differentiation and the distribution of bargaining power between the upstream and the downstream firm, over the pair-specific input price.
