Modularity and productivity: Assessing the impact of digital technology in the U.S. telecommunication industry

This article investigates the impact of digital technology diffusion on the productivity of firms making up the local operating sector of the U.S. telecommunications industry for the years 1991 to 1993. Diffusion of digital technology is measured as the extent of line digitalization that has taken place, with digitalization expected to enable firms to reap significant operating efficiencies. While the diffusion of this particular technology in the local operating company sector has been relatively low, it is found that, after controlling for the effects of a number of other covariates also likely to affect firm-level performance, the spread of digital technology within the U.S. local telephone network plays a significant and positive role in impacting productive efficiency of the firms making up the network. The investments that have been made in energizing the U.S. information superhighway, via the digitalization of telephone lines, are justified in productive efficiency terms. The article contributes to empirical literature in the technical change area which assesses the firm-level productive efficiency consequences of technology diffusion.     

Technological change and the spatial restructuring of data entry and processing services

Technological change in the data entry and processing industry has profound implications for the future location and nature of industry jobs. Without specific policies, rural areas of the U.S. will be the clear jobs losers as improvements in telecommunications and imaging technologies accelerate the movement offshore of data entry. The urban-anchored firms in this industry are increasingly specialized and provide unique products designed in conjunction with clients. One implication is that these firms will remain located near urban markets and use higher-skilled labor. These activities will not filter down to rural economies.     

Structural Change And Innovation In U.S. Telecommunications

This paper reexamines broadly. from the standpoint of innovation, the arguments for vertical integration in the U.S. telecommunications industry in light of structural change since the breakup of the Bell System. While basic and applied research became the casualty of the 1984 breakup and the 1995 AT&T split, there is no evidence that the pace of innovative activity and productivity has slowed. Evidence from R&D and patent data suggests some acceleration of innovative activity. However. the service segment of the industry ceased to be the center of technological innovation. The source of future innovation seems to lie in the telecommunications and Internet equipment firms and independent software firms. The emergence of the competitive stand-alone software industry, combined with a trend towards open operating systems and customer demand for greater flexibility, and growing substitution of technology alliances for in-house R&D appear to have undermined the case for vertical integration in the telecommunications industry. From the standpoint of business strategy, the question of whether a firm like AT&T, notwithstanding its huge investments in cable facilities, can develop distinctive and sustainable capabilities through horizontal expansion and ubiquity and one-stopshopping marketing alone remains open.     

What are good R&D investment strategies for leaders and followers?

Research and development (R&D) investment affects the growth of firms in the same industry differently according to their technological positions. This study empirically investigates differences in how R&D investment influences firm growth between technological leaders and followers. Additionally, this study investigates the moderating effects of complementary assets and market competition on the relationship between R&D investment and firm growth. Using a sample of 2322 observations from 492 firms in the U.S. chemical and allied products industry for the period 2000–2009, we show that an increase in R&D investment leads to greater firm growth for technological followers than for technological leaders. We also find that the moderating effects of complementary assets and market competition vary depending on whether a firm is a technological leader or follower.     

Effects of technical innovation on market value of the U.S. semiconductor industry

This article discusses the effects of technical innovation on the market value (MV) of the American semiconductor industry from the perspective of investors in the securities market. The study quantifies the technical innovations of the semiconductor industry and uses the proportional change of Average Process Technology (APT) as a proxy variable to measure the industrial capability of technical innovations and to act as one of the explanatory variables of a regression model for discussing the connection between technical innovation and MV. The results indicate that: 1) the degree of technical innovation and the proportional change in productivity of the semiconductor industry are the major factors that affect proportional change in the MV of the U.S. semiconductor industry; 2) regardless of the size of a company's MV or the companies' classification in terms of products and services (the Equipment & Material Sector, the Board Line Sector, the IC & Chip Sector and the Fabless & Specialist Sector), the degree of technical innovation shows a significant positive effect on MV.     

CERCLA AND DEEP POCKETS: MARKET RESPONSE TO THE SUPERFUND PROGRAM

This paper uses event study methods to estimate wealth effects upon shareholders who are named by the U.S. Environmental Protection Agency (EPA) as potentially responsible parties at a Superfund site. Impacts appear to be divided into three periods: an initial program period where stock market effects depend largely on prior visibility of the site, a second period where likely financial impact is more important, and a third period where notification has little association with either visibility or financial measures. However, the expected remediation cost burden is not borne evenly. "Deep-pocket" firms appear to be disproportionately penalized by the market during the second period.     

Heterogeneity in Production Structures and Efficiency: An Analysis of the Czech Food Processing Industry

The present study analyses firm heterogeneity and sector‐specific technology. The theoretical model stands on the assumption of maximizing the return on capital and overcomes problems involved in simple profit maximization. The results show that a random parameter model with sector dummies and heteroscedasticity is the most appropriate model specification for distinguishing firm‐level and sector‐level efficiency and heterogeneity. The heterogeneity among firms as well as among sectors was found to be an important characteristic in Czech food processing. This holds for production technology as well as for technical efficiency. Moreover, the decomposition of total variance shows that intrasectoral differences in technologies are much more pronounced than the intersectoral differences. The differences in intrasector heterogeneity also suggest that the food processing industry will be subject to accelerated structural change in the coming years. Moreover, we found that on average the companies highly exploit their production possibilities. However, some companies cannot keep pace with competitors. Because leapfrogging does not appear to be present in selected industries (except for Milling), structural change is expected to occur in such a way that the most successful companies will strengthen their position.     

How technological innovation affects the structure of an industry: entrepreneurship evolution in the biotechnology and pharmaceutical industry since 1980

Challenges faced by the biotechnology and pharmaceutical industry, including reduced R&D productivity and the expiration of drugs that are high in demand, are recently being addressed through technological innovation. Such innovations are highly likely to change the structure and functioning of the industry. Since 2000, biotechnology and pharmaceutical companies have actively made strategic alliance, and technological innovations have changed the source of innovation from R&D to entrepreneurship within the industry. In this study, we identify the evolution of entrepreneurship and discuss the changes caused by technological advancements since 1980 by analysing patterns of exporting and acquiring technology data from Medtrack. Over difference period, biopharmaceutical firms have gained new knowledge and improved technology, and have implemented this newly acquired knowledge and innovation to introduce drugs to the market.     

Market Size and the Survival of Foreign‐owned Firms*

We develop a general equilibrium model with heterogeneous firms and foreign direct investment cost uncertainty and investigate the survival of foreign‐owned firms. The survival probabilities of foreign‐owned firms depend on firm‐level characteristics, such as productivity, and host country characteristics, such as market size. We show that a foreign‐owned firm will be less likely to be shut down when its parent firm's productivity is higher and its indigenous competitors are less productive. Although a larger market size will always reduce the survival probability of indigenous firms, it can lead to a higher survival probability for foreign‐owned firms if their parent firms are sufficiently productive.     

Efficiency in the factoring industry

The efficiency and productivity in the Italian factoring industry between 1993 and 1997 is investigated using DEA. The factoring industry is an important part of many financial systems and it has established itself as a major source of finance and credit management for a growing number of companies. However, as far as the authors are aware no studies have applied frontier methodologies to examine the efficiency and productivity of this industry. This paper focuses on the Italian market, the second largest in the world after the UK. The results suggest that there are substantial cost savings to be had in the Italian factoring industry: the mean cost inefficiency in the Italian factoring industry over the period 1993–1997 ranged between 14% and 22%. These inefficiencies are mainly generated by allocative rather than technical inefficiencies. Scale and technical inefficiencies seem to be similar in magnitude and the supposed importance of the latter typically found in the banking efficiency literature, are not observed in Italian factoring. Firm size does not appear to be related to technical, allocative and economic efficiency and the hypothesis that ownership structure influences factoring firm efficiency could not be rejected. In order to analyse efficiency change over time the Malmquist index is used. Total factor productivity was decomposed into technical change and efficiency change and the latter was further divided into pure efficiency and scale efficiency change. Productivity changes were slight over the period 1993–1996, while a substantial increase in productivity occurred between 1996 and 1997: the latter appears to be the result of a large improvement in the technology and a positive scale efficiency change, however, this was slowed down by a negative pure efficiency change.

The relation between the average complexity of high-tech products and their diversity: An empirical test of evolutionary models

What is the relation between the average level of complexity that characterizes a product's technology, and the degree of diversity of that technology across rival firms? Evolutionary theories of innovation and technical advance are consistent with either a direct or an inverse relation. The issue thus becomes an empirical one. This paper uses a unique database containing detailed quantitative data on the specifications of 12 high-tech product groups for the U.S., Japan and selected European countries, for 1982, for both products and processes. It is found that the more complex the technology, the less diverse is the technology of rival firms that produce the product. This is consistent with the following evolutionary process: Economies of scale and scope inherent in high-level technologies require firms who adopt them to dispose entirely of older technologies, in order to remain competitive; at the same time, older, simpler technologies continue to exist and permit wide diversities among firms who pursue “niche” market strategies.     

THE DETERMINANTS OF THE INTER-INDUSTRY PATTERN OF DIVERSIFICATION BY U.K. MANUFACTURING ENTERPRISES*

Evidence of the diversity of output of larger U.K. manufacturing enterprises’in 1958, 1963 and 1968 is provided in the Reports on the Census of Production. The Censuses show that between 1958 and 1968 diversification was a significant and general trend in manufacturing industries and an important element in the growth of firms during the period. Moreover diversification seems to be part of a longer term trend in U.K. industry and part of the typical development pattern of the large firm. A theory of the firm's diversification decision is proposed and from this theory predictions are made of the structural features both of a firm's primary industry and of outside industries which are likely to encourage diversification from the one industry to the other. The power of the model in explaining the pattern of diversification between SIC manufacturing orders in the period 1963–68 is weak, due in part to the wide variety of factors influencing diversification and to the aggregated form of the data. Nevertheless, the results show the importance of research and development effort in encouraging diversification and the stimulus to diversification given by profitability and risk in firms’primary industries and high rates of output growth in outside industries. While the findings offer no clear conclusions regarding the impact of diversification upon economic performance, the results are consistent with the propositions that (i) diversification encourages technical progress in industry and (ii) diversification increases the efficiency with which resources are allocated between industries.     

Credit market imperfections and persistent unemployment

This paper develops the thesis that credit market frictions may be an important contributor to high unemployment in Europe. When a change in the technological regime necessitates the creation of new firms, this can happen relatively rapidly in the U.S. where credit markets function efficiently. In contrast, in Europe, job creation is constrained by credit market imperfections, so unemployment rises and remains high for an extended period. The data show that there has not been slower growth in the most credit dependent industries in Europe relative to the U.S., but the share of employment in these industries is lower than in the U.S. This suggests that although credit market imperfections are unlikely to have been the major cause of the increase in European unemployment, they may have played some role in limiting European employment growth.     

Firm selection and industry evolution: the post-entry performance of new firms

A dynamic framework based on the process of firm selection and industry evolution is used to analyse the post-entry performance of new firms. In particular, it is hypothesized that, based on the stylized fact that virtually all new firms start at a very small scale of output, firm growth and survival are shaped by the need to attain an efficient level of output. The post-entry performance of more than 11,000 U.S. manufacturing firms established in 1976 is tracked throughout the subsequent tenyear period. Firm growth is found to be negatively influenced by firm size but positively related to the extent of scale economies, capital intensity, innovative activity, and market growth. By contrast, the likelihood of survival is identified as being positively influenced by firm size, market growth, and capital intensity, but negatively affected by the degree of scale economies in the industry. When viewed through the dynamic framework of firm selection and industry evolution, the empirical results shed considerable light on several paradoxes in the industrial organization literature, such as the continued persistence over time of an asymmetrical firm-size distribution consisting predominantely of suboptimal scale firms, and the failure of capital intensity and scale economies to substantially deter the entry and start-up of new firms.     

Matching Industries between Target and Acquirer in High-Tech Mergers and Acquisitions

Mergers and acquisitions (M&As) have been regarded as a highly viable option for fostering innovation, gaining new products or services, and gaining access to new markets in high technology firms. This study analyzes several alternative variables that impact M&A choices by analyzing their relationship to the industry of both the acquirer and target. Results support two hypotheses implying that (1) M&A transactions with the same acquirer and target industry are more likely to be acquisitions that delivers a greater final share of the target organization to the acquirer, and (2) acquirers are more likely to invest greater dollar amounts in targets that have the same primary industry.

Market Underreaction and Overreaction of Technology Stocks

Several studies have assessed stock market under- or overreaction of stocks and there is some agreement among them. However, there is much disagreement about what constitutes market underreaction or overreaction, and the conditions that cause it. The substantial variation in results among studies may be partially attributed to the types of firms that are contained in any sample. We investigate this premise by focusing on a sample of technology stocks that experienced an extreme change in stock price, along with a corresponding control sample of non-technology stocks that experienced a similar extreme change in stock price on the same day.

Based on the subsequent stock price behavior of each sample, we find a greater degree of overreaction within extreme positive changes in technology stock prices (winners) than in non-technology stock prices. In addition, we find a greater degree of underreaction within extreme negative changes in technology stock prices (losers) than in non-technology stock prices. When considering winners and losers collectively for technology and non-technology firms, it appears the market is overoptimistic when it initially revalues technology stock prices relative to non-technology stock prices.

The degree of under- or overreaction of technology stocks varies within the sample of technology stocks, and is conditioned on firm-specific characteristics. Overall, our results suggest that technology stocks exhibit unique stock price behavior subsequent to an extreme change in price, and that this unique behavior can even vary among technology firms according to firm-specific characteristics.     

THE IMPACT OF DECONTROL ON GASOLINE WHOLESALERS AND RETAILERS

Since decontrol of the U.S. gasoline market in January 1981, substantial changes in operations of gasoline retailers (dealers) and wholesalers (jobbers) have occurred. This paper analyzes decontrols impact on the operations of these two classes of firms. A primary conclusion is that removing regulations allowed dealers to profit by cutting prices and margins for self-service gasoline, while increasing prices and margins for full-service gasoline. In addition, decontrol resulted in lower jobber margins and profitability, which in turn caused a substantial number of jobbers to exit from the market. Overall, removal of the regulations allowed operational changes which were consistent with emerging technology and consumer demands, but which had been constrained by a decade of pervasive federal regulation of the U.S. gasoline market. Thus, decontrol fostered greater economic efficiency in the marketing of gasoline, which contributed to lower gasoline prices during a time of rising gasoline taxes and increasing general inflation.
