SPINOFFS AND THE MARKET FOR IDEAS*

We present a theory of entry through spinoffs where workers generate ideas and possess private information concerning their quality. Because quality is privately observed, adverse selection implies that the market can only offer a price that reflects the average quality of ideas sold. Only workers with good ideas decide to spin off, whereas workers with mediocre ideas sell them. Existing firms pay a price for ideas sold in the market that implies zero expected profits. Hence, firms’ project selection is independent of firm size, which can lead to scale‐independent growth. This mechanism results in invariant firm‐size distributions that resemble the data.     

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.     

Antidumping Regulations: Anti‐Competitive and Anti‐Export

In a Bertrand duopoly model, it is shown that an antidumping regulation can be strategically exploited by the home firm to reduce the degree of competition in the home market. The home firm commits not to export to the foreign market which gives the foreign firm a monopoly in its own market. As a result the foreign firm will increase its price allowing the home firm to increase its price and its profits. If the products are sufficiently close substitutes then the higher profits in the home market are large enough to compensate for the loss of profits on exports.     

Market access and technology adoption in the presence of FDI

This paper theoretically investigates whether improved access to the domestic market speeds up new technology adoption by foreign firms. Foreign firms choose between exporting and foreign direct investment (FDI) to serve the domestic market. If two firms compete in the domestic market, multilateral liberalization of FDI or the realization of multilateral free trade may deter or delay technology adoption, while they always promote and accelerate technology adoption if only a single firm serves the domestic market. Technology adoption can be quickest and consumer welfare greatest when the fixed cost of FDI and the trade costs are neither very high nor very low. Preferential liberalization of FDI promotes the technology adoption of the targeted firm but may not benefit consumers because it discourages technology adoption of the non-targeted firm.     

ON THE RELEVANCE AND COMPOSITION OF GIFTS WITHIN THE FIRM: EVIDENCE FROM FIELD EXPERIMENTS*

We investigate the economic relevance and the composition of gifts within a firm where output is contractible. We develop a structural behavioral model that identifies workers’ optimal reaction to monetary gifts received from their employer. We estimate the model using data from two separate field experiments conducted within a tree‐planting firm. We use the estimated structural parameters to generalize beyond the experiment, simulating how workers would react to different gifts on the part of the firm, within different labor market settings. We find that gifts have a role to play within this firm, increasing in importance when the workers’ outside alternatives deteriorate. Profit‐maximizing gifts would increase profits within slack labor markets by up to 10% on average and by up to 17% for certain types of workers.     

Some thoughts on the Sutton approach

I analyze the relation between market size and number of firms when an endogenous number of firms chooses the market strategy and (simultaneously or sequentially) an R&D investment. I generalize the linear Cournot model with an endogenous cost-reducing activity and show that, as long as exogenous fixed costs are positive, the market structure is naturally characterized by an inverted-U relation between market size and number of firms, in line with the celebrated hypothesis of Sutton. However, the increase of the market size reduces the prices and expands individual investment and production exactly as in endogenous market structure only with exogenous fixed costs.     

Price competition when consumer behavior is characterized by conformity or vanity

It has long been recognized that the pleasure of consuming a good may be affected by the consumption choice of other consumers. In some cases, social pressures may lead to conformity; in some others, individuals may feel the need of exclusiveness under the form of vanity. Such externalities have proven to be important in several markets. However, the market implication of these externalities are still unclear. To investigate them, we propose to combine the consumption externality model and the spatial duopoly model. When conformity is present but not too strong, both firms remain in business but price competition is fiercer and results in lower prices. The market share of the large firm increases with the population size; as the population keeps rising, the large firm may serve the entire market and set a price that has the nature of a limit price. When conformity is strong enough, different equilibria may exist. In most of these equilibria, a single firm captures the whole market. At the other extreme, when vanity is at work, price competition is relaxed.     

Coordination Costs,Market Size,and the Choice of Technology

Impact of coordination costs and market size on a firm's choice of technology is studied in a general equilibrium model in which finns engage in oligopolistic competition. A firm establishes an organizational hierarchy to coordinate its production. First, it is shown that an increase in market size leads a firm to choose a more specialized technology. Second, surprisingly, a robust result is that an increase in the level of coordination efficiency leads a firm to choose a less specialized technology.     

Pay inequality and firm performance: evidence from matched employer–employee data

A large matched employer–employee data set for Sweden is used to test several predictions from tournament theory. For white-collar workers a positive and significant effect of intra-firm wage dispersion on profits and average pay is found, using various measures of wage dispersion. This result is robust for controlling for firm differences in human capital and firm fixed-effects as well as for instrumenting the wage dispersion variable to take into account endogeneity of wage dispersion. Using data on around 10?000 managers, a positive and significant association between pay dispersion and profits is also found for executives. Further results include a positive relationship between market demand volatility and wage dispersion, measured as coefficient of variation in managerial pay, and a negative effect of the number of managers (contestants) on managerial pay spread. The first two results are in accordance with predictions from tournament theory, while the last one is not.     

Media Plurality: Private versus Mixed Duopolies

In this paper, we analyze the level of media plurality in a market with two private news firms (private duopoly) and in a market with a private news firm and a public news firm (mixed duopoly). In the private duopoly news firms maximize profits. In the mixed duopoly, the private news firm maximizes profits, while the public news firm maximizes social welfare. We show that, in spite of the public news firm maximizing social welfare, neither media plurality nor social welfare needs to be higher under the mixed duopoly compared with the private duopoly. This will depend on the relation between the costs of adapting news to readers' political preferences, the intensity of the readers' political preferences, and the size of the advertising market.     

Infrastructure regulation and reallocations within industry: Theory and evidence from Indian firms

Many firms in developing countries adopt captive power generators to deal with expensive and unreliable supply of electricity. I present a model that combines upstream regulation with downstream heterogeneous firms in a monopolistic competition framework, where firms can pay a fixed cost to adopt this marginal cost-reducing device. The presence of captive power affects the market equilibrium by increasing the level of idiosyncratic productivity a firm needs to survive in the market and by re-allocating sales and profits towards the more productive, adopting firms. Additionally, the rate of adoption is shown to increase with the price of electricity, industries' electricity–intensity and with higher barriers to firm entry. The mechanisms I propose are present for a cross-section of Indian firms.     

PRODUCT LINE RIVALRY

We analyse how product line rivalry by multi‐product oligopolists is affected by market size and product substitutability. We show that the width and degree of overlap in competing product lines is determined by the tension between two effects: the drive to ‘be where the demand is’ and the desire to weaken competition and intra‐firm product cannibalization. Product lines are shown to be wider and more overlapped in large markets and when product substitutability is weak. Our analysis suggests that firms can increase their profits by agreeing not to overlap their product lines.     

规模经济、异质性企业及其国际化——对Krugman模型的一般性扩展

出口的"本地生产、异国销售"特征,会使企业获得产量增加导致的规模经济效应。笔者证明了如果这个效应足够大,即使国外市场的利润为负,企业仍然可能选择出口,这是对Melitz模型的一个修正:企业生产率即使达不到ZCP条件也可以出口。加入规模经济因素后,Krugman模型的本地市场效应,Melitz模型的自选择效应,张杰等模型的制度质量效应都可以纳入本文统一的分析框架。     

Impact of international trade under dual labor markets

A country's unemployment rate can be affected by technology choice and the opening of international trade. This general equilibrium model examines the impact of international trade with the presence of dual labor markets in which manufacturing firms engage in oligopolistic competition and choose technologies with different marginal and fixed costs to maximize profits. In a closed economy, it is shown that an increase in labor market efficiency or a population increase induces manufacturing firms to adopt more advanced technologies and the wage rate in the manufacturing sector increases. With the existence of a continuum of technologies, technology choice is not a source of firm heterogeneity. The opening of international trade leads to an increase in the wage rate in the manufacturing sector and the price of the agricultural good. When countries are identical, international trade always increases national welfare.     

BUBBLES,CRASHES, AND ENDOGENOUS UNCERTAINTY IN LINKED ASSET AND PRODUCT MARKETS*

In laboratory asset markets, subjects trade shares of a firm whose profits in a linked product market determine dividends. Treatments vary whether dividend information is revealed once per period or in real time and whether the firm is controlled by a profit‐maximizing robot or human subject. The latter variation induces uncertainty about firm behavior, bridging the gap between laboratory and field markets. Our data replicate well‐known features of laboratory asset markets (e.g., bubbles), suggesting these are robust to a market‐based dividend process. Compared to a sample of previous experiments, both real‐time information revelation and endogenous uncertainty impede the bubble‐mitigating impact of experience.     

Constant returns to scale and competitive equilibrium under uncertainty

This paper considers the implications of the assumption of constant returns to scale in expected utility maximizing models of the competitive firm or industry in which markets for risk are absent. Under widely used assumptions about risk preferences it is shown that with constant returns to scale average profits are more than necessary to cover the implicit costs of risk-bearing. When the free entry of identical firms is possible this assumption about technology is shown to be incompatible with the assumption that entrepreneurs are risk averse.     

Market size and entry in international trade: Product versus firm fixed costs

This paper develops a theoretical framework to infer the nature of fixed costs from the relationship between entry patterns in international markets and destination market size. If fixed costs are at the firm level, firms take advantage of an intrafirm spillover by expanding firm‐level product range (scope). Few firms enter with many products and dominate international trade. If fixed costs are at the product level, an interfirm spillover reduces the fixed costs to export for all firms producing the product. The resulting entry pattern consists of many firms exporting different varieties of the same product. Using cross‐country data on firm and product entry, I find empirical evidence consistent with product‐level costs. More firms than products enter in larger markets offering their consumers lower prices and a greater variety of goods within the product category.     

Towards an economic theory of the multiproduct firm

This paper outlines a theory of the multiproduct firm. Important building blocks include excess capacity and its creation, market imperfections, and the peculiarities of organizational knowledge, including its fungible and tacit character. A framework is adopted in which profit seeking firms are seen to diversify in order to avoid the high transactions costs associated with using various markets to trade the services of various specialized assets. Neoclassical explanations of the multiproduct firm are shown to be seriously deficient.     

Digital Platforms and the Nature of the Firm

Abstract:

Digital platforms turn traditional approaches of the firm, which relied on the wage relation to explain the major difference between firm and market, upside down and underline the advantages of coordination through organization over coordination through market. This study aims to propose a definition of the firm able to integrate, besides the integrated firm, also hybrid forms such as networks of subcontractor/subcontracting firms as well as atypical forms such as digital platforms. By reactivating the firm-boundary problem, this article suggests putting valorization by labor at the heart of the firm’s decisions concerning integration. It suggests therefore a general definition of the firm as a techno-institutional center of capital valorization, provided that firms make profits by means of the appropriation of labor incorporated into their (productive, structural, intellectual) capital through institutional arrangements. By stressing the relation of production between the owners of the means of production and the direct producers, the approach of the firm supported here should allow to cover the different existing models of the firm, from the classical firm to hybrid models, around which the boundary debate has revolved, to digital platforms.     

Information technology, organizational form, and transition to the market

The paper reviews theories of information technology adoption and organizational form and applies them to an empirical analysis of firm choices and characteristics in four transition economies: Czech Republic, Hungary, Romania, and Slovakia. We argue that two major structural changes have occurred, one concerning technology and another concerning firm ownership and boundaries, and we consider how each change may have affected the other. We estimate the impact of firm size, integration, and ownership on new information technology adoption and the impact of information technology on changes in firm boundaries and ownership, using a sample survey of 330 firms.
