How should firms carry out technological diversification to improve their performance? An analysis of patenting of Korean firms

This research aims to analyze how a firm's technological diversification strategies influence its financial performances, in terms of ‘technological diversification’ in broad technology sectors and ‘technological concentration’ on its own core technology, especially in the case of Korean large firms. The data used in the analysis were panel data encompassing the years between 1990 and 2006, which linked Korean firms’ patent information registered in the United States Patent and Trademark Office to the financial data of those firms collected from Korea Investors Service, Inc. (Kis-Value). For the estimation of the panel data, a fixed effect model, which considers the individual firms’ own effect on the financial performance, was used. Tobin's q was used as a dependent variable representing firm performance, while ‘broad technology diversity’ and ‘core technology diversity’ were used as the focal explanatory variables. The results show that a firm seeking to have more technological assets should invest in a broad technological diversification strategy in its search for new business opportunities; it should likewise concentrate on the core technology in order to maintain its financial performance.     

Comparison of Some Static Hedging Models of Agricultural Commodities Price Uncertainty

In static framework, many hedging strategies can be settled following the various hedge ratios that have been developed in the literature. However, it is difficult to choose among them the best the appropriate strategy according the to preference or economic behavior of the decision-maker such as prudence and temperance. This is so even with the hedging effectiveness measure. After introducing a hedging ratio that take into account the prudence and temperance of the decision maker, we propose a ranking based approach to measure the effectiveness using L-moment to classify hedge portfolios, hence hedge ratios, with regard to their performance. Moreover, we deal with the hedging issue in presence of quantity and rollover risks and derive an optimal strategy that depends upon the basis and insurance contract. Such hedging issue includes the relevant risks encountered in practice and we relate how insurance contract, specially designed for production risk could affect the futures hedge. The application on some agricultural futures prices data at hands shows that taking into account quantity and rollover risks leads to better hedging strategy based on the L-performance effectiveness measure.

     

R&D portfolios in environmentally friendly automotive propulsion: Variety, competition and policy implications

In this article, we analyze R&D portfolios in environmentally friendly automotive propulsion including alternative fuel options. We argue that at the current stage of development, substitution of conventional car technology by a new automotive propulsion technology may lead to premature lock-in of suboptimal technology. To avoid such lock-in, one should value the variety of current R&D activity that enables organizations to learn from multiple options and to create spillovers between options. We further argue that the existence of technological variety is not a sufficient condition to avoid lock-in. Organizational variety is also required to sustain competition and avoid the dominance of few firms that possibly enforce a suboptimal technology within the sector. To assess whether recent developments in R&D have led to both technological variety and organizational competition, we analyze United States Patent and Trademark Office (USPTO) patents in low-emission vehicles (LEVs) during the period 1980–2001 using entropy statistics. Results show that both technological variety and organizational competition have increased steadily since the early nineties, suggesting that premature lock-in is unlikely to occur. From an environmental policy evaluation perspective, we consider the findings as a positive evaluation of the 1990 Californian Low Emission Vehicle program.

Technology flows between sectors and their impact on large-scale firms

In this article we highlight the importance of technology flows between sectors and their impact on the labour productivity of large-scale corporations. Based on theoretical considerations, we explore technological spillovers between the sectors of an economy. Large-scale corporations usually focus on certain sectors but make use of a wide range of technological knowledge from other sectors. Thereby, technological knowledge built up in sectors by continuous R&D activities does not spill over without bounds but is directed by firms’ absorptive capacities. We use firms’ patent portfolio to empirically calculate the sector affiliation and therewith the firms’ absorptive capacities in order to estimate the impact of technology diffusion on labour productivity. Fortune 500 firms serve as data base.     

Exchange rate exposure: Evidence from China

This paper examines exchange rate exposure using a sample of Chinese firms. To measure RMB exchange rate volatility and jump risk, we apply the autoregressive conditional jump intensity (ARJI) model to the industry‐specific nominal effective exchange rate (I‐NEER) for 13 Chinese manufacturing industries over the period 2001 to 2017, We find that exchange rate risks do affect firm value at the industry level, and the effect is more significant for the jump risks that are more difficult to hedge and in the sample period when hedge activities are less likely to occur. Our results suggest that the exposure puzzle could be a result of the endogeneity of operative and financial hedging. Firm‐level analysis finds that exchange rate risk affects firm value for more than 20% of Chinese firms, and a firm's exchange rate exposure varies with the firm's characteristics.     

The propensity to hedge using futures contracts: the case of potato futures contracts

This paper studies why UK non-financial firms hedge with potato futures contracts. It is found that the financial characteristics of firms in the sample play an important role in influencing the propensity to hedge. For example, it is found that firms that hedge are on average larger than firms that do not hedge. Firms that hedge also have more volatile earnings. Furthermore, firms that do hedge appear to want to smooth earnings to reduce the costs of financial distress and avoid entering the highest tax threshold.     

Multi-currency options and financial institutions' hedging: Correlation does matter

This paper examines one element of financial institutions doing business internationally: currency exchange risks. Such risks present significant barriers to profitably and competitively expand financial service markets. This paper compares the cost of alternative options hedging schemes in the presence of multi-currency uncertainties that affect the repayment of financial institutions' portfolios of loans (assets) and debt. Schemes that use separate contracts to hedge each uncertainty are compared to schemes with a single contract to capture all uncertainties simultaneously. The impact of correlation between the different currencies on such hedging policies is investigated. It is found that correlation matters and can significantly affect the cost and the contract choice.The authors greatly appreciate comments from participants at the International Atlantic Economic Conference in Boston, MA, October 8–11, 1998 and the Office of Thrift Supervision research seminar.     

Vertical alliance portfolios and the business performance of small technology-based firms

This paper discusses how small technology-based firms (STBFs) effectively manage vertical alliances by choosing proper alliance structures to both manage challenges and pursue higher performance. We consider the main challenges of STBFs’ vertical alliances as opportunistic risk and coordination concern between partners, and derive four types of vertical alliance portfolios with different extents of risk and return based on the relational perspective. We then examine the impact of each portfolio on performance and the moderating effect of STBFs’ age and technological capability. The results show the portfolio focusing on bilateral alliances is not helpful for STBFs, while the others are useful. The portfolio focusing on unilateral alliances promises young firms better performance, while hybrid portfolios of unilateral and bilateral alliances are more helpful for older STBFs. In hybrid portfolios, bilateral alliance in the upstream is beneficial to specific technology-focused firms, while bilateral alliance in the downstream is recommended to STBFs whose technology covers a wider range.

Properties of knowledge base and firm survival: Evidence from a sample of French manufacturing firms

The paper analyzes the effects of the properties of firms' knowledge base on the survival likelihood of firms. Drawing upon the analysis of the patterns of co-occurrence of technological classes in patent applications, we derive the coherence, variety and cognitive distance indexes, accounting respectively for technological complementarity, differentiation and dissimilarity in the firms' patent portfolios. The results of our analysis are in line with the previous literature, showing that innovation enhances the survival likelihood of firms. In addition, we show that the search strategies at work in the development of firms' knowledge base matter in reducing the likelihood of a failure event. Knowledge coherence and variety appear to be positively related to firms' survival, while cognitive distance exerts a negative effect. We conclude that firms able to exploit the accumulated technological competences have more chances to be successful in competing durably in the market arena, and derive some policy implications concerning the role of public intervention in the orientation of search efforts in local contexts.

Does corporate governance still affect firm performance after controlling the distress factor?

We explore the impact of corporate governance on firm performance. We first identify whether corporate governance can still be an influential factor or has been largely captured by the traditional Fama-French three-factor model. More importantly, our study adds a financial distress factor to the Fama-French three-factor model to form a four-factor pricing model (labelled as the ‘financial distress four-factor model’). We find that for the US Russell 1000 firms, the financial distress four-factor model is the better model of the two models considered. We further find that the financial distress four-factor model has a higher explanatory power in capturing the return variation. We find that the differences between the return of firms with good (weak) corporate governance and the expected return are insignificantly different from zero for most portfolios in all the two models. The financial distress four-factor model, however, has the fewer portfolios with return difference being significantly different from zero, implying that corporate governance has been better priced in the financial distress factor.     

外部知识搜索对制造企业技术创新的影响——知识协奏能力的中介作用与创新意愿的调节作用

知识是企业技术创新的基础，企业不仅要搜索外部知识，还应具备知识协奏能力。基于知识基础理论和资源协奏理论，将外部知识搜索分为搜索宽度和搜索深度两个维度，探讨二者对企业技术创新的影响，并研究知识协奏能力的中介作用和创新意愿的调节作用。结果表明，搜索宽度和搜索深度均对知识协奏能力有显著正向影响，知识协奏能力对企业技术创新有显著正向影响，且知识协奏能力分别在搜索宽度、搜索深度与企业技术创新之间起部分中介作用。此外，创新意愿在知识协奏能力与企业技术创新之间起调节作用。结论揭示了外部知识搜索对企业技术创新的内在作用机理，可为制造企业知识协奏能力和技术创新水平提升提供理论支持。     

Knowledge combinations and the survival of financial services ventures

The paper investigates the role of knowledge in the evolution of new financial services ventures in Sweden between 1990 and 2002. Drawing upon economic theories of human capital and spin-out entrepreneurship, we investigate whether knowledge from prior employment in the financial and technological industries facilitates the survival of new entrepreneurial firms. Based on a database tracking the evolution of 1,077 financial services ventures, we find that firms with more extensive knowledge from the financial services and high-tech sectors have higher chances of survival than firms with more narrow knowledge bases. Our findings offer contributions to the emerging literature on spin-out entrepreneurship and to research on entrepreneurship in services.     

Cross-Hedging of Exchange-Rate Risk

For currencies with highly developed forward markets a well-known separation theorem holds which implies that international firms fully hedge the exchange rate risk if the forward markets are unbiased. In this paper we present a model of a risk-averse firm when perfect hedging instruments are not available. Instead the firm can cross-hedge the exchange-rate risk by using the forward markets of a third country's currency. We demonstrate that the unbiasedness of all forward markets does not imply full hedge, although the firm has the option to hedge all the risks.     

Australian financial firms’ exposures to the level,slope, and curvature of the interest rate term structure

This study examines the risk exposure of Australian financial firms to changes in the term structure of interest rates. Non-linearity in the interest rate term structure is captured by the three-factor model of interest rate level, slope, and curvature. We observe that financial firms have negative exposures to the interest rate level, while non-financial firms have positive exposures. This finding suggests that financial firms need to hedge against rising interest rates, while non-financial firms need to hedge against falling interest rates. Small banks and insurance companies have a positive risk exposure to the slope factor, while real estate firms have a negative risk exposure to the curvature factor. Though the interest rate level is the most important factor, ignoring the slope and curvature factors could lead to underestimating a financial firm’s overall interest rate risk exposure. These findings are robust to controlling for the orthogonalized market return, time-varying equity risk premium, and the global financial crisis. This study offers practical tools to regulators, such as the Reserve Bank of Australia and Australian Prudential Regulatory Authority for assessing interest rate risk exposures of the financial and non-financial sectors.     

Visibility,Institutional Preferences and Agency Considerations

We show that market frictions and agency considerations are important concerns when institutional investors make portfolio allocation decisions. For a sample of widely followed firms, institutional holdings increase with increases in visibility as measured by the number of analysts following the firm. We also report a significant seasonal pattern in institutional holdings consistent with the gamesmanship hypothesis, which asserts that institutions rebalance their portfolios in response to agency considerations. Finally, we find that excess returns are highly seasonal with performance, deteriorating when the following by financial analysts increases. "Followed" firms actually exhibit inferior market performance over the 1981-1996 sample period.
