Product innovation,product–market competition and persistent profitability in the U.S. pharmaceutical industry

Increasingly, strategy scholars are exploring the relationships between innovation, competition, and the persistence of superior profits. Sustained high profitability may result when a firm repeatedly introduces valuable innovations that service previously unmet consumer demands. While the returns to the firm from each innovation may erode over time, innovation ensures that, overall, the firm maintains a high performance position. At the same time, sustained high profitability may also accrue to firms that innovate less often, but effectively avoid the competition that otherwise erodes high returns. This paper elaborates these relationships before presenting an empirical analysis of the effects of differential innovative propensities and differential rates of competition on pharmaceutical firms’ abilities to sustain profit outcomes that are above those earned by competing firms. The analysis, which is situated within the U.S. pharmaceutical industry, finds support for the expected relationship between high innovative propensity and sustained superior profitability, but no support for a link between persistence and the ability to avoid competition.

Innovation,R&D productivity,and global market share in the pharmaceutical industry

In this paper, we estimate two empirical models using a pooled, cross-section sample of international pharmaceutical firms for the period 1987 to 1989. The first model tests the relationship between R&D productivity and a vector of firm-specific characteristics. The second model tests the determinants of global market share. The empirical analysis reveals three findings. First, we find evidence that there are diminishing returns in the pharmaceutical R&D process. Second, we find that firm size has a positive effect on average R&D productivity and a positive impact on the marginal R&D productivity for plausible R&D staff sizes. And third, we find evidence that R&D productivity and the number of sales employees have a positive effect on the firm's global market share.The views presented in this paper reflect those of the authors and do not necessarily reflect the views of the U.S. International Trade Commission or any of its individual commissioners.

Asymmetric Volatility, Correlation and Returns Dynamics Between the U.S. and U.K. Securitized Real Estate Markets

We construct synchronously priced indices of securitized property listed on the New York Stock Exchange and London Stock Exchange. The indices are then utilized to examine dynamic information flows between the two markets. By analyzing returns behavior, asymmetric volatility spillover effects and exceedance correlations, this study shows that the real estate markets in these two countries experience significant interaction on a daily basis when synchronously priced data are utilized. These results are different from when close-to-close returns are examined, implying that the use of close-to-close data can misconstrue the true dynamics that exist between these markets. Results also show significant asymmetric effects on both the volatility and correlation dynamics between the markets. This has several implications for property portfolio managers, indicating that positive and negative news impact the markets differently. This is particularly true for the United Kindom, where daily foreign news from the United States can influence U.K. volatility.     

An empirical analysis of sustained advantage in the U.S. pharmaceutical industry: impact of firm resources and capabilities

The authors test a model of the relationships among firm resources, firm capabilities, and sustained competitive advantage between 1971 and 1989. Sustained comparative advantage was captured by two variables: therapeutic differentiation and global NCEs. The results show that R&D and salesforce expenditures have indirect and direct effects, respectively, on sustained competitive advantage. Firm capabilities were differentiated into component and integrative capabilities. Component capabilities were captured by the firm’s internal R&D efforts and therapeutic market focus, while integrative capabilities were concerned with the firm’s ability to obtain FDA approvals and to develop radical new drugs. Findings on each of these four capabilities on therapeutic differentiation and global NCEs are mixed. The direct and indirect effects of these resources and capabilities on therapeutic differentiation and global NCEs suggest important managerial implications in the way firms coordinate and combine their assets so as to achieve sustained competitive advantage.

Profitability, productivity and price recovery patterns in the U.S. telecommunications industry

We undertake a study where we examine changes in the profitability, productivity and price recovery of firms in the U.S. telecommunications industry over a sixteen-year period. We assess the performance of thirty-three major companies in the local-exchange sector over six time periods 1975, 1978, 1981, 1984, 1987 and 1990, using a performance analysis model which disaggregates the profitability measure into two components: productivity and price recovery. We demonstrate the computation of performance using this technique. Our study indicates that the opening up of markets has had a significant impact on different dimensions of performance in the telecommunications industry, also validating a number of theoretical assumptions about the impact that industry changes are expected to have on firms.     

Determinants of technology cycle time in the U.S. pharmaceutical industry'

The focus of this study is to examine different factors that influence a firm's technology cycle time. The U.S. pharmaceutical industry is analyzed from 1977–1991. Specifically, the sample includes 21 firms that (a) primarily produce brand ethical drugs, (b) are publicly-owned companies, and (c) have pharmaceutical sales account for a substantial portion of company sales.
Our measure of faster technology cycle time is positively correlated to measures of the knowledge base level of firms, the breadth of firms' knowledge bases, size, and age; it is negatively correlated to advertising expenditures and the percent of US. firm sales to total sales. However, the most notable finding is that technology cycle time is significantly faster for firms that predominantly generate new knowledge internally, and slower for firms that rely more on external sources of new knowledge.     

Spatial Linkages in Returns and Volatilities among U.S. Regional Housing Markets

This article investigates spatial linkages in returns, idiosyncratic risks and volatilities across 19 U.S. regional housing markets. Using Case & Shiller housing price indices from 1995 through 2009, we find that interconnections across markets can be “wider” and “stronger” than would normally be expected. They are “wider” because, in addition to geographic closeness, economic proximity is also an important source of influence; they are “stronger” because of the significant contagion effects during the 2007–2009 subprime and financial crises. The increased comovement and interdependence, especially among more geographically diverse regions with similar economic conditions, may help explain the failure of geographic portfolio diversification strategies.     

Entry timing,exploration, and firm survival in the early U.S. bicycle industry

We explore the relationship between a firm's entry timing and its probability of surviving the early, uncertain period of its industry, and consider the trade‐off between entering early and potentially establishing a strong position in the industry vs. waiting until technological uncertainty is reduced. We hypothesize that, owing to inertial forces, firms that enter the industry at the earliest point in its history are least likely to make the conversion to the product generation that becomes the dominant design in the industry. Exploration through the introduction of new products appears to reflect a local search process and retards the transition to the dominant design. We also hypothesize that, though firms entering early may exhibit longer life spans, their advantages are limited to the period before the emergence of the dominant design. We test our hypotheses in the early U.S. bicycle industry, and find evidence consistent with the idea that inertia limits firms' abilities to make the transition between generations of product configurations.

Long run competition in the U.S. aluminum industry

A methodology for examining dynamic structure-performance relationships in a single industry is proposed and illustrated. Implications of long run competitive behavior for a simple simultaneous equations model of structure and performance are derived and tested using recently developed methods for the interpretation of economic time series. It is concluded that the structure and performance in the U.S. aluminum industry in the postwar period conform well with the hypothesis that the primary aluminum market was competitive in the long run.     

A longitudinal study of the cause and consequences of changes in diversification in the U.S. pharmaceutical industry 1977–1986

The paper hypothesizes that diversification by firms based in the pharmaceutical industry during the 1977-86 time period was primarily undertaken to reduce the risks associated with being dependent upon a technologically dynamic environment. Consistent with this non-efficiency motive for diversification, declining economic performance is predicted. A longitudinal empirical analysis provides support for these propositions.     

The value of knowledge spillovers in the U.S. semiconductor industry

This paper aims at quantifying the economic value of knowledge spillovers by exploring information contained in patent citations. We estimate a market valuation equation of the U.S. semiconductor firms during the 1980s and 1990s, and find an average value of $0.6 to 1.2 million “R&D-equivalent” dollars for knowledge spillovers embodied in one patent citation. For an average semiconductor firm, such an estimate implies that the total value of knowledge spillovers the firm received during the sample period can be as high as half of its actual total R&D expenditures in the same period. This provides a direct measure of the economic value of social returns or externalities of relevant technological innovations. We also find that the value of knowledge spillovers declines as the size of firm's patent portfolio increases, and that self citations are more valuable than external citations, indicating a significant amount of tacit knowledge or know-how spillovers that occur within the firm.     

Insights into the contestability and sustainability of the U.S. petroleum refining industry

Contestable market theory has been advanced in recent years by several authors, the most thorough treatment being the book by Baumol, Panzar, and Willig (1982) (BPW). Although several applications of the theory have appeared in the literature, few (if any) follow the step-by-step procedure set forth in Chapter 16 of BPW. This paper represents one of the first attempts to follow the general procedure in investigating the contestability and sustainability of an industry. The long-run cost structure of petroleum refining is first estimated using a translog multiproduct cost function and company refining data from the Financial Reporting System maintained by the U.S. Energy Information Administration (EIA). The estimated cost function is then used to approximate the optimal (cost-minimizing) industry structure for petroleum refining. Given that the existing structure is significantly different than the optimal structure, the principles of contestable market theory are used in evaluating the contestability and sustainability of the industry in light of adjustments in industry structure and the performance of various classes of refining companies between 1981 and 1987.     

Survivors of industry shake-outs: The case of the U.S. color television set industry

In this article survivors and non-survivors of the ‘shake-out’ in the U.S. color television set industry are compared to determine how and along what dimensions these two classes of businesses differ. Two types of strategy variables are used in 18 hypotheses to probe similarities and differences at both the ‘corporate level’ and ‘business level’ of strategy. Significant differences are found, particularly at the business level. The findings are consistent with those of previous strategy research, but suggest that traditional wisdom regarding size, low costs and market share did not necessarily hold in this industry.     

Evidence of directional price discrimination in the U.S. airline industry

This paper explores possible determinants that may affect an airline’s decision to charge passengers different roundtrip fares depending on trip origin, a case of directional price discrimination. Such fare differences cannot be the result of differences in cost, as the cost of flying a roundtrip passenger does not significantly differ depending on direction. It is argued that directional fare differences result from airlines recognizing that passenger price elasticities differ between route endpoints. A price discriminating airline will then charge a higher roundtrip fare at the endpoint where the passenger price elasticity of demand is comparatively lower. Evidence is found suggesting that airlines do use differences in income to price discriminate when setting roundtrip fares. Fares are found to be $0.18-$0.43 higher on average for each $1000 difference in average per capita income between origin and destination metro areas. This finding is sensible assuming that higher incomes reduce the price elasticity of demand for air travel, with richer passengers being less sensitive to the cost of travel.     

美国的敏捷零售模式对中国服装零售业的借鉴

70年代末到80年代初美国服装业陷入了市场需求变幻不定;服装总体消费连续下降的困难境地,促使美国服装业建立了快速反应机制。与此同时,美国服装零售商也深刻认识到:在纺织这条长产业链上,建立快速反应机制不仅仅是制造商的事,零售业作为联结制造商与最终消费者的关键环节和服装产业价值链的末端,建立对市场变化快速有效的反应新机制更为重要。于是一种以现代信息技术为条件,以零售商与制造商之间新型的行业关系为基础的敏捷零售模式出现了。本文分析对比了美国传统服装零售与敏捷服装零售的特点,以期为中国服装零售的发展提供一些思路。     

Testing for market power in the U.S. motor carrier industry

During the 1980's, researchers noted a trend towards increased concentration in the general freight, less-than-truckload (LTL) portion of the U.S. motor carrier industry. The purpose of this study is to employ new empirical industrial organization techniques to determine whether the more concentrated, post-1980, LTL industry exerted monopoly pricing behavior and to compare the nature of pricing behavior before and after regulation reform. The results suggest that the trend toward increased industry concentration does not imply anti-competitive performance. Also, the results indicate the presence of regulation-induced market power several years prior to regulation reform in 1980.     

Strategic groups,competitive groups and performance within the U.K. pharmaceutical industry: Improving our understanding of the competitive process

Strategic group research originated in the 1970s and a number of notable studies centered on the U.S. pharmaceutical industry. Results were, however, conflicting. This paper explores the nature of strategic groups in the U.K. pharmaceutical industry. The study confirms the presence of between six and eight strategic groups across the period studied, 1998–2002. The study also demonstrates a statistically significant relationship between these strategic groups and performance using three performance measures. The paper then compares strategic groups with competitive groups and concludes that the distinction is important and may explain the contradictory findings in earlier strategic group research.

Japanese/U.S. technological competitiveness and strategic alliances in the biotechnology industry

This paper analyzes the reasons for Japanese/U.S. collaborations in the biotechnology industry, and considers the question of whether such alliances pose a threat to the North American industry. Japan's technological competitiveness in biotechnology is examined in terms of its strengths and perceived weaknesses. Ways in which Japan is attempting to overcome these weaknesses are identified. As well, the strengths and weaknesses of the North American biotechnology industry are assessed. The paper concludes with recommendations for government and R&D managers on how to preserve U.S. competitiveness. R&D managers must keep abreast of their techno-global competitive environments. While organizations can enter into alliances to improve their competitiveness they must be aware of the dangers of collaboration, and to benefit from their alliances they must enhance their organizational learning. Organizations must be aware of the pitfalls of alliance formation, and any alliance must be viewed in its national context. Last, but not least, managers must be more effective in their management of the processes of technological innovation.
