Mixed Oligopoly at Free Entry Markets

We investigate the optimal behavior of a public firm in a mixed market involving private firms and one public firm. Existing works show that welfare-maximizing behavior by the public firm is suboptimal when the number of firms is given exogenously. We allow free entry of private firms and find that, in contrast to the case with the fixed number of firms, welfare-maximizing behavior by the public firm is always optimal in mixed markets. Furthermore, we find that mixed markets are better than pure markets involving no public firm if and only if the public firm earns nonnegative profits.     

Partial Privatization in a Differentiated Mixed Oligopoly

A model of differentiated mixed oligopoly is developed to systematically discuss the welfare consequences of partial privatization of a public firm. We analytically derive the optimal degree of partial privatization not only in the short run with restricted entry but also in the long run with free entry. It is shown that the short-run optimal policy is non-monotonic in the degree of love of variety, while the optimal degree of privatization is monotonically increasing in the consumer's preference for variety in the long run.

Management of Foreign Market Entry： A Study of Czech Companies

Internationalization of company activities is the necessity of the development for majority of entrepreneurial subjects in the Czech Republic. Internationalization of entrepreneurial activities becomes a tool of business competitiveness. Selecting the right foreign entry mode is an important decision, which demands a lot of resources and thorough planning. The factors influencing company＇s choice of entry mode are divided into two main groups subsuming--external and internal factors. External factors consist of determinants regarding the company＇s environment while the intemal ones are determined by the company＇s specific factors. The opening of new markets such as in the Czech Republic has created the potential for small and medium-size enterprise （SME） expansion and investment. The objective of this paper is to present an application of the entry modes of the selected Czech entrepreneurial subjects. The companies included in the study are those that have undertaken internationalization activities and are incorporated in the Czech Republic. There were a total of 297 enterprises that participated in the research. The research method was an oral questioning and the main instrument was a questionnaire. A relatively low degree of Czech companies that have undergone intemationalization has resulted in the dominance of the least advanced forms of internationalization expansion, mainly exports with a small share of more advanced forms of foreign direct investments and a very low level of forms of international cooperation. Czech companies are in decision about the choosing the foreign entry mode influenced by the many factors. The greatest influence on the choice of foreign entry mode has entry mode variables. Entry mode variables constitute variables assessment characteristics of particular entry mode.     

Stock markets in transition: the Warsaw experiment1

This paper investigates the development from 1991 to 1994 of the Warsaw Stock Exchange, which opened on April 16th, 1991. An overview is presented focusing first on the deepening of the equity market, with a still limited but increasing number of listed companies, and then on the high trading activity and price dynamics with their impressive outburst in 1993. Three important dimensions are thereafter analyzed: the relevance of organizational and regulatory choices, the degree of market inefficiency and the origin of the discrepancy between IPO prices and first quoted market prices. Concluding remarks concentrate on the market's ability to fulfil its fundamental tasks.     

Modelling upstream and downstream market power in bilateral oligopoly

This article develops a general model that estimates market power exertion in a bilateral market relationship for processors and retailers where each may also have market power in their primary input market and output markets, respectively. Monte Carlo experiments are used to generate industry data for market structures such as perfect competition, monopoly, monopsony, bilateral imperfect competition with an integrated processor/retailer, bilateral imperfect competition with separate processor and retailer, and bilateral imperfect competition with four adjacent upstream and downstream markets. Then, new empirical industrial organization models are estimated using the data with models that match the market structure under which the data were generated (true) and with models that reflect alternative market structures (alternative). The general model is derived using the production function approach without imposing the fixed proportion assumption. Monte Carlo simulation results indicate that the general model is preferred to alternative models that presume competitive behaviour by processors in primary input procurement and by retailers in the output market. Results indicate that less flexible models lead to biased market power estimates in the presence of market power in the corresponding input and output markets.

MARKET‐DEMAND BOOSTING AND PRIVATIZATION IN A MIXED DUOPOLY

This study incorporates demand‐boosting strategies into a mixed duopoly model in order to consider the endogenous determination of market demand. The results indicate equilibrium characteristics that differ from those found under an exogenous demand setting. As consumers become more sensitive to the demand‐boosting strategies of firms, the government must choose a lower level of privatization. This suggests that the responsiveness of consumer demand to the demand‐boosting strategies of firms constitutes a limiting factor for privatization.     

The Impact of Cost Changes on Industry Entry and Exit

Increases in costs may have interesting, non-obvious effects on industry entry and exit. Three cases are possible when costs rise: the competitor neutral case, in which entry decreases and exit increases, entrant favoring, in which entry and exit both increase, and incumbent favoring, in which entry and exit both decrease. The model places restrictions on which outcomes are possible given which costs rise (marginal or fixed). The model can be used to examine the impacts of cost-increasing regulation or exogenous process innovation on industry entry and exit.

SOE Reform under Oligopolistic Market Structure: The Optimal Choice of State Shares

This paper examines the effect of the change of state shares in a state-owned enterprise (SOE) on the efficiency of the whole society and the payoff of the government. This issue is addressed by setting up a mixed oligopolistic competition model and dividing the analysis into two cases: closed economy and open economy. The basic results are as follows: If the relative production efficiency of an SOE is too low, complete state ownership is not optimal, and privatization will be a necessary step; however, if the relative production efficiency of an SOE is not too low, complete privatization is not optimal both for the government and from the perspective of social welfare. The results can, to a certain extent, provide theoretical support to the governments idea on the SOE reform. Translated from Economic Research Journal, 2004, 1 (in Chinese)     

Internationalization and the Structure of the Company＇s Marketing Strategy on International Markets Theoretical Remarks

The paper presents theoretical reflection upon international marketing strategy in the framework of internationalization and globalization of the market. It consists of four parts. The first one debates the nature and reasons for corporate internationalization. The second part shows an international marketing strategy in the concept of corporate expansion. The strategy consists of two elements： the basic dimensions of foreign market entry modes （part 3） and business presence strategies in overseas markets （part 4）. This paper proposes a theoretical framework for research conducted by Department of Marketing of the Cracow University of Economics. The research has been conducted as a part of grant received by Polish National Centre of Science.     

异质性企业贸易理论的起源与发展

本文旨在系统性地探究异质性企业贸易理论的起源与发展过程。首先对促使该理论诞生的实证挑战从企业的选择性出口、市场进入成本、资源再分配三个方面进行了综述;然后指出该理论发展的两条脉络和各自的理论基础,并在此基础上从平均生产率和贸易利得两个角度阐述了异质性企业贸易理论和新贸易理论之间的紧密联系,二者最大的差别便在于对边际生产成本的处理上,前者以边际成本的异质性替代企业的异质性,后者则忽略了企业之间的异质性。同时,针对国内学者的一些认识,本文也提出了自己的看法。     

Welfare Effects of Foreign Direct Investment: Cost Saving vs. Signaling

We compare the effects of two types of foreign direct investment (FDI) (viz., FDI for trade cost saving and FDI for signaling foreign cost of production) on consumer surplus, profit of the host-country firm and host-country welfare. We show that the effects are dramatically different. If the reason for FDI is to save trade cost, FDI (compared to export) always makes the consumers better off and the host-country producer worse off, while the effect on host-country welfare is ambiguous. However, if the FDI is to signal the foreign cost of production, FDI (compared to export) always makes the host-country producer better off and increases host-country welfare, while it makes the consumers almost always worse off.     

FDI and domestic investment in Germany: crowding in or out?

This paper estimates the effects of outward FDI on domestic business investment in Germany at the industry level for a panel of 19 industry and 10 services sectors. We pay particular attention to the different motivations behind FDI, and distinguish between FDI to high-versus low-wage countries, to Europe versus the rest of the world, and FDI in services and industry sectors.We find that, in industry, FDI to low-wage countries crowds out domestic investment, whereas FDI to high-wage countries outside Europe crowds in domestic investment. In services, FDI to Western Europe crowds in domestic investment.
