Innovation and integration in the agri-food industry

We deal with the link between innovation and market structure using the empirical example of the Danish agri-food industry. Vertical integration may resolve hold-up problems and here we test for the importance of vertical integration and networks on innovation. We further examine the effects of network relationships on innovation behaviour. We use data from an extensive survey of 444 Danish firms over two years, 2000 and 2005 to estimate a bootstrapped zero-inflated Poisson regression model. The first and most significant result is that organization matters. Further we find that vertical integration as well as contractual arrangements are significant determinants for firms’ innovation behaviour. The direction of integration is important as well. Also, economies of size seem to play an important role. Similarly, the export orientation of the firm is a significant determinant of innovation whereas the sector the firm is operating in is not significant for its innovation behaviour.     

Does the fourth entrant make any difference?: Entry and competition in the early U.S. broadband market

We study the importance of sunk costs in determining entry conditions and inferences about firm conduct in an adapted Bresnahan and Reiss (1991, 1994) framework. In our framework, entrants incur sunk costs to enter, while incumbents disregard these costs in deciding on continuation or exit. We apply this framework to study entry and competition in the local U.S. broadband markets from 1999 to 2003. Ignoring sunk costs generates unreasonable variation in firms' competitive conduct over time. This variation disappears when entry costs are allowed. Once the market has one to three incumbent firms, the fourth entrant has little effect on competitive conduct.     

Sunk Costs,Extensive R&D Subsidies and Permanent Inducement Effects

Using firm‐level data on Spanish manufacturing firms we estimate a model of the firm's optimal R&D decisions (whether to perform R&D and how much to invest). We quantify the fixed (proper fixed costs plus firms' outside option) and sunk costs of R&D and find the former to be substantially higher than the latter. While sunk costs act as a barrier to entry into R&D for some firms, fixed costs are the binding obstacle for many more firms. Simulation based on the estimated model reveals that one‐shot trigger subsidies cause a substantial increase in both the share of R&D firms and average R&D expenditures. This effect shows persistence over time, but totally fades away after seven years as firms are gradually hit by negative R&D profitability shocks.     

Export behavior of Italian food firms: Does product quality matter?

Using firm-level data we investigate the export behavior of Italian food firms, focusing on the link between total factor productivity (TFP), product quality, and export across heterogeneous destinations. We test the main predictions of an international trade model based on firm heterogeneity in product quality and non-homothetic preferences in consumption. In this setting, the firm’s export intensity should be increasing in the per-capita income of foreign destinations, and the effect should be largely driven by firms’ heterogeneity in product quality. Using different measures of revenue-TFP, and different proxies for product quality, we find strong support for the main model predictions. Moreover, consistent with the Alchian–Allen effect, we find a positive relationship between the quality of exported products and the distance of destination countries.     

Sunk Costs,Accommodation, and the Welfare Effects of Entry

Although economists usually support the unrestricted entry of firms into an industry, entry may lower social welfare if there are setup costs or if entrants have a cost disadvantage. We consider the welfare effects of entry within a standard Cournot model where some of an incumbent firm’s costs are sunk. We find that the range of parameter values over which entry can harm welfare declines monotonically in the fraction of cost that are sunk. Furthermore, the presence of even a small fraction of sunk costs often reverses an assessment that entry harms welfare.     

Hysteresis and export targeting

A direct and largely untested implication of hysteresis concerns the extent of market entering and leaving in response to large movements in exchange rates. This note examines, for 359 4-digit U.S. SIC industries, data on the distribution of U.S. exports by country of destination (a proxy for the number of markets served) from 1978 to 1987 and relates changes in these distributions to overall exchange rate movements. We seek to explain differences in the response across industries on the basis of differences in sunk costs. The empirical results are generally consistent with the hysteresis approach. While in periods of general dollar depreciation firms spread exports more widely across foreign markets, this effect is seen to be limited in industries with relatively large distribution and media advertising costs, for which much of the costs of establishing export networks may be sunk.     

Employer discrimination and market structure: Does more concentration mean more discrimination?

We formalize Gary Becker’s dynamic conjecture that competitive forces drive discriminating employers from the market in the long run, using a dynamic model of a monopolistically competitive industry characterized by sunk costs and sequential entry. An advantage of this formalization is that it demonstrates the importance of the structure of production costs, as well as market power, in explaining the long-run survival of discriminatory firms. In addition, we show that, despite decades of empirical research on this connection, there is no consistent theoretical relationship between the degree of market concentration within an industry and the degree of discrimination. However, we do find an indirect link in which market liberalization has a more pronounced effect in reducing discrimination in more concentrated markets.     

基于沉淀成本视角的企业重组博弈分析

本文从放松新古典完全竞争市场中没有沉淀成本的假设前提入手,在区分固定成本和沉淀成本概念的基础上,运用一个有无沉淀成本的古诺纳什均衡经济模型分析它们各自对企业重组的经济效率和福利水平的不同影响,进而发现,沉淀成本而不是固定成本(规模经济或企业规模)是影响企业重组经济效率和福利水平最基本的经济变量。依据这样的经济模型,我们发现,在国有企业重组过程中,因资产专用性、交易成本和生产过程等原因,沉淀成本普遍存在,严重降低了国有企业重组的经济效率和福利水平。因此,为了提高国有企业重组的经济效率,我们提供制度创新或政策创新的基本原则,关键在于减少或补偿沉淀成本,促进生产要素充分流动,从而创造出一个可竞争的市场经济环境。     

THE ROLE OF SUNK COSTS IN THE DECISION TO INVEST IN R&D*

We present a dynamic empirical model of a firm's R&D decisions that is consistent with the existence of sunk R&D costs, taking into account that these costs may differ between small and large firms, and among different technological regimes. We estimate a multivariate dynamic discrete choice model using firm‐level data of Spanish manufacturing for 1990–2000. Conditional on firm heterogeneity and serially correlated unobservable factors, we find that R&D history matters. This true state dependence allows inferring the existence of sunk R&D costs associated with performing R&D. Sunk R&D costs are found to be higher for large, high‐tech firms.     

Sunk Costs,Market Contestability,and the Size Distribution of Firms

In this paper we offer a new economic explanation for the observed inter-industry differences in the size distribution of firms. Our empirical estimates based on three temporal (1982, 1987, and 1992) cross-sections of the four-digit US manufacturing industries indicate that increased market contestability, as signified by low sunk costs, tends to reduce the dispersion of firm sizes. These findings provide support for one of the key predictions of the theory of contestable markets: that market forces under contestability would tend to render any inefficient organization of the industry unsustainable and, consequently, tighten the distribution of firms around the optimum.     

Firm entry and firm growth

This paper reports on the importance of firm entry and growth flows in Portuguese manufacturing during the period 1982–86, and investigates their determinants. We find that both movements are induced by past profitability and deterred by economies of scale, product differentiation and sunk costs. The analysis does not reject the hypothesis that the determinants of firm entry and growth are quantitatively the same, thereby giving some support to the hypothesis that entry and expansion are close substitutes in absorbing industry excess profits, and that the choice between them does not depend on the height of the entry/mobility barriers.     

Entry and Exit Behavior in the Absence of Sunk Costs: Evidence from a Price Comparison Site

This paper explores entry and exit at a price comparison site (PCS) where the sunk costs of participation are effectively zero. We first use an unbalanced panel of 295 products on NexTag.com to estimate an error correction model of net entry. Although the results support our characterization of the PCS as a zero sunk cost market in which potential sellers behave as Kirznerian entrepreneurs in responding to opportunities, it is clear the net entry flow involves participants with widely differing behavior. This is investigated by examining exit and re-entry decisions at the seller level, which reveal that size and reputation determine individual responses to market opportunities.     

The impact of firm cost and market size asymmetries on national mergers in a three-country model

This paper studies the impact of firm cost and market size asymmetries on merger decisions. I consider a model where a small and a large country compete in a third (world) market. Each of the two countries has two firms (with potentially different costs) that supply the domestic market and export to the third market. Merger decisions in the two countries are modeled as a simultaneously move game. The paper finds that firms in the large country have more incentives to merge than firms in the small country. In contrast, the government of the large country has more incentives to block a merger than the government of the small country. Thus, the model predicts that conflicts of interest between governments and firms concerning national mergers are more likely in large countries than in small ones.     

Speed to Market for Innovative Products: Blessing or Curse?

The relationships among speed to market, quality, and costs are important to managers as they attempt to best establish incentives and set goals for new product development teams, allocate resources for new product development, or create positional advantage in the market. The existing literature suggests that the economic consequences of being late to the market are significant, including higher development and manufacturing costs, lower profit margins, and lessening of the firm's market value. Therefore, traditional logic has held that new product development managers need to manage the trade‐offs among speed to market, quality, and costs. While both scholars and managers have often acquiesced to performance trade‐offs among “faster, better, and cheaper,” this research attempts to improve understanding of the interrelationships between these objectives, and ultimately profit. Based on a survey of 197 managers, faster speed to market is shown to be related to better quality and lower costs; it is not necessary to sacrifice one of these outcomes. Further, the moderating roles of two dimensions of innovativeness (innovativeness to the firm and to the market) are examined on the relationships between speed and quality, as well as speed and profit. Both dimensions of innovativeness positively moderate the relationship between speed to market and quality. For more innovative products (both to the firm and the market), there is a stronger positive relationship between speed and quality than for less innovative products. Further, innovativeness to the firm negatively moderates the relationship between speed and profit. Thus, speed has a less positive impact on profit for highly innovative‐to‐the‐firm products compared with less innovative‐to‐the‐firm products. By being conscious of the projects’ levels of innovativeness (along with prioritizing various performance measures), managers can more rationally decide when to emphasize speed to market based on this study's findings.     

Sunk Costs and the Depth and Probability of Technology Adoption

I propose that sunk costs of learning and the output over which these costs are spread determine the probability and depth of technology adoption. Depth of adoption describes the extent to which firms exploit the advantages of the technology. I find that plant size but not firm size predicts CAD and CNC adoption. Learning costs are lumpy, are closely connected to technology adoption and determine both the probability and depth of adoption. Depth of adoption is considerably more plant idiosyncratic than the decision to adopt.     

Downstream mergers in vertically related markets with capacity constraints

Motivated by a recent merger proposal in the French outdoor advertising market, we develop a model in which firms are initially endowed with some advertising capacities and compete on two fronts. First, firms compete to acquire additional advertising capacities on an upstream market; a first stage modeled as a second-price auction with externalities. Second, those firms, privately informed on their own costs, use their capacities on the downstream market to supply advertisers whose demand is random; a second stage modeled by means of mechanism design techniques. We study the linkages between the equilibrium outcomes on both markets. When a firm is endowed with more initial capacity, through the acquisition of a competitor for instance, whether it becomes more or less eager to acquire extra capacity on the upstream market depends a priori on fine details of the downstream market. Under reasonable choices of functional forms, we demonstrate that a downstream merger does not create any bias in the upstream market towards the already dominant firm.     

An Exploratory Analysis of the Impact of Market Orientation on New Product Performance

For many firms, emphasizing the importance of market orientation has taken on a mantra-like quality. Mission statements and memos, policies, and procedures all highlight the importance of staying in touch with the customer. It is also widely assumed that the relationship between market orientation and new product performance depends on environmental conditions and product characteristics. To date, however, little empirical evidence has been presented to support the assumption that market orientation influences new product performance. Kwaku Atuahene-Gima addresses this research need in a study of 275 Australian firms. In addition to exploring the relationship between market orientation and new product development activities and performance, his study examines the effects of environmental conditions and product characteristics. Specifically, the study investigates whether the relationship between market orientation and new product performance depends on the degree of product newness to customers and the firm; the intensity of market competition and the hostility of the industry environment; and the stage of the product life cycle at which the new product was introduced. The survey results provide strong support for the basic proposition that market orientation influences new product performance and development activities. The results show a strong positive relationship between market orientation and a new product's market performance. Market orientation is also shown to have a strong positive effect on proficiency of predevelopment activity, proficiency of launch activity, service quality, product advantage, marketing synergy, and teamwork. Although market orientation is generally found to be an important factor in the success of new products, its influence varies depending on the type of new product—that is, radical versus incremental. Market orientation appears to have greater influence on new product performance when the product represents an incremental change to both the customers and the firm. However, this does not mean that a market-oriented approach is unnecessary in the development of radically hew products. Market orientation also has a greater effect when the perceived intensity of market competition and industry hostility are high, and during the early stage of the product life cycle. Because market competition and industry hostility typically intensify as the product life cycle progresses, these findings suggest that the effects of market orientation are pervasive. In other words, managers should not limit their expectations of market orientation to specific projects or specific stages of the development process and product life cycle.     

Market Structure, R&D and Advertising in the Pharmaceutical Industry

Recent developments in the literature on market structure have allowed the generation of a few key testable predictions from the theory of strategic behaviour. The seminal model considers one simple but general relationship, that between market structure and market size, focusing on the competitive roles of endogenous sunk costs in the form of advertising and/or research and development (R&D). Evidence presented in this case study, building on earlier econometric work, shows that such endogenous sunk costs do play a crucial role in the formation of market structure in the global pharmaceutical industry.     

个人理性与沉没成本悖论

文章放松了新古典经济学条件下沉没成本决策无关性假设前提,进而从真实世界角度阐述沉没成本悖论存在的理性逻辑,从而表明人们很难忽略过去发生的沉没成本,它本身并不能被视为一种悖论或错误行为,甚至是非理性行为,同样也是在约束条件下一种广义理性行为。因此,需要承认沉没成本悖论存在的普遍性,而且还需要采取恰当的非正式和正式制度设计克服沉没成本悖论所带来的负面影响,并不是简单地警告我们不要考虑过去发生的沉没成本,＂让过去的事情过去吧＂的规范结论。因此,不仅需要提高决策者的认识能力,更多需要采取加强沉没成本与风险管理,创造一个良好的市场环境是最为根本的。
