Technological Diversification, Coherence, and Performance of Firms

Technological diversification at the firm level (i.e., the expansion of a firm's technology base into a wide range of technology fields) is found to be a prevailing phenomenon in all three major industrialized regions,—the United States, Europe, and Japan—prompting the term multitechnology corporation. Whereas previous studies have provided insights into the composition of technology portfolios of multitechnology firms, little is known about the relationship between technological diversification and firms' technological performance. Against a backdrop of the technology and innovation management literature, the present article investigates the relationship between technological diversification and technological performance, taking into account the moderating role of technological coherence in firms' technology portfolios. Hereby, technological coherence is defined as the degree to which technologies in a technology portfolio are technologically related. To measure the technological coherence of portfolios, a measure of technological relatedness of technology fields is constructed based on patent citation patterns found in 450,000 European Patent Office (EPO) patent grants. Two hypotheses are presented here: (1) Technological diversification has an inverted U‐shaped relationship with technological performance; and (2) technological coherence moderates the relationship between technological diversification and technological performance positively. These hypotheses are tested empirically using a panel data set (1995–2003) on patent portfolios pertaining to 184 U.S., European, and Japanese firms. The firms selected are the largest research and development (R&D) actors in five industries: pharmaceuticals and biotechnology; chemicals; engineering and general machinery; information technology (IT) hardware (i.e., computers and communication equipment); and electronics and electrical machinery. Empirical results, obtained by fixed‐effects negative binomial regressions, support both hypotheses in the present article. Technological diversification has an inverted U‐shaped relationship with technological performance. Technological diversification offers opportunities for cross‐fertilization and technology fusion, but high levels of diversification may yield few marginal benefits as firms risk lacking sufficient levels of scale to benefit from wide‐ranging technological diversification, and firms may encounter high levels of coordination and integration costs. Further, the results show that the net benefits of technological diversification are higher in technologically coherent technology portfolios. If firms build up a technologically coherent diversified portfolio, the presence of sufficient levels of scale is ensured and coordination costs are limited. At the same time, technologically coherent diversification puts firms in a better position to benefit form cross‐fertilization between technologies. The present article clearly identifies the important role of technological coherence in technology diversification strategies of firms.     

Reevaluation of Revaluations: A Cross-Country Examination of the Motives and Effects on Future Performance

Abstract:  This study examines the motives for asset revaluations in a sample drawn from 35 countries that permit asset revaluations. Prior studies that examined this issue concentrated on one or two countries, the UK and Australia, and showed that revaluations are related to financing needs, the capital intensity of the firm as well as issues related to political costs. The previous literature also found that revaluations were indicators of improved future performance and that performance was related to the magnitude of the revaluations. This study shows that although the conclusions drawn from the previous studies are applicable to countries that are similar to the UK and Australia, they do not hold when applied to a much larger set of countries and that the motivations for and effects of revaluation are not uniform across various country classifications.     

Exchange Rates, Pricing- to-Marke t Strategies, and the Marshall-Lerner Condition

This paper reexamines the relationship between the Marshall-Lerner (M-L) condition and the effects of exchange-rate movements on the trade balance, by integrating the role of product-market structure and the related issue of strategic interaction on tradeables prices and international flows.     

The guppy and the whale: Relational pluralism and start-ups' expropriation dilemma in partnership formation

Start-ups have a high need for resources yet face significant risks when forming partnerships with incumbents to access those resources. We propose that a partnership strategy based on relational pluralism, forming multiplex and multifaceted ties with partners, can mitigate these risks. Such ties offer the start-up increased legitimacy and a relational safeguard against resource misappropriation by more powerful partners. However, we propose that there is a limit to the effectiveness of relational pluralism. Its effect is weakened when the start-up becomes entirely dependent on a small set of partners, or when an additional tie yields resources that are redundant. We argue that the start-up only benefits when the gains from relational safeguarding and legitimacy outweigh the costs of dependence and redundancy. We empirically observe the co-evolution of start-ups’ interlocking directorate and strategic alliance networks in the Australian mining industry over a 10-year period. Our results show that start-ups that engage in relational pluralism perform better than both start-ups that form no alliances and start-ups that form stand-alone alliances. Having a very small portfolio of partners or one that skews heavily toward local partners, however, indeed limits the effectiveness of relational pluralism. Intriguingly, we also find that the temporal sequencing of relational pluralism matters. One of our central findings is that the best performing start-ups first form board interlocks with promising partners and add a strategic alliance later. This offers a rare glance at the temporal sequencing in which peripheral start-ups can gain exceptional performance through partnership formation.     

From Core to Periphery? Recent Developments in Employment Relations in the Philippines

We seek to describe recent developments in employment relations in the Philippines, placing these developments in the contexts of the distinctive elements of the Philippine social/political/industrial relations systems as well as the ongoing trade-based and functional integration of international markets and the recent regional economic crisis. We find that while some firms are pursuing functional flexibility and more cooperative employment relations, the logic of competition primarily has induced firms to adopt practices that promote numerical flexibility such that a core-periphery workforce is created. We argue that the labor movement in the Philippines has been hampered in its efforts to effectively counter employer strategies by its low density and fragmentation and an unfavorable public-policy environment; Philippine labor unions have, however, made some recent gains in organizing and interunion coordination. We also argue that the government has not done enough to counteract the negative effects of market integration on workers nor to evolve th e Philippines into a higher-value-added exporter.     

The Impact of Economic Shocks in the Rest of the World on South Africa: Evidence from a Global VAR

The substantial change in South Africa’s trade patterns over the past two decades has affected the impact of economic shocks in major world economies on South Africa. To investigate the effect, we use a global vector autoregression (GVAR) model with time-varying trade weights to account for changing international trade linkages. We show that the long-term impact of a shock to Chinese GDP on South African GDP is much stronger in 2009 than in 1995, due to the substantial increase in South Africa’s trade with China since the mid-1990s. At the same time, the importance of the U.S. economy to South Africa diminished considerably. The results indicate one of the possible reasons why the recent global crisis did not affect South Africa as much as it affected developed economies. It also stresses the increased risk, to the South African and other economies, should China experience slower GDP growth.     

Do Domestic Investors Have an Edge? The Trading Experience of Foreign Investors in Korea

We investigate whether domestic investors have an edge overforeign investors in trading domestic stocks. Using Korean data,we show that foreign money managers pay more than domestic moneymanagers when they buy and receive less when they sell for mediumand large trades. The sample average daily trade-weighted disadvantageof foreign money managers is 21 basis points for purchases and16 basis points for sales. There is also some evidence thatdomestic individual investors have an edge over foreign investors.The explanation for these results is that prices move more againstforeign investors than against domestic investors before trades.
