Multicomponent signals and financial constraints

ABSTRACT

The inventive process creates knowledge asymmetries between research-intensive firms and external investors, making it difficult for firms to obtain funding for inventive activities. Consequently, most research-intensive firms face financial constraints (FC). Some suggest patents act as signals to reduce asymmetries, attracting external financing. Yet, prior findings are mixed. We integrate literature on FC with signaling to explore these inconsistent conclusions. We argue ambiguity in previous studies results from examining patents as sending a single signal. We examine impacts of three firm-level attributes on FC – use of emergent technology inputs, firm age, and repeat alliance partners. We demonstrate consideration of multiple simultaneous signals provides better insights into the patenting-FC relationship.     

The rise of 3D printing and the role of user firms in the U.S.: evidence from patent data

3D printing has been heralded as one of the key technologies for the Fourth Industrial Revolution but empirical analysis is still sparse. This paper provides empirical evidence by proposing a robust approach to identifying 3D printing inventions. Findings indicate the inventive activity has been rapidly growing since 2011 and is mainly led by user firms. The development of 3D printing has taken place in a variety of industrial sectors, not merely a specific sector. This implies 3D printing can be considered as a general purpose technology. Interestingly, the diffusion patterns of 3D printing vary across technological categories. User firms are divided into incumbent and new firms to examine how patent activities vary by the type of firm and time. Incumbent firms exploit 3D printing earlier than new firms do but new firms tend to enter into 3D printing space more than incumbent firms after the technology becomes prevalent.     

Firm size and inventive activity: The evidence reconsidered

This paper analyses the relationship between firm size and inventive activity in the United States for the late seventies. It is argued that the inventive activity measure used, R&D expenditure, is a more ‘neutral’ measure in relation to firm size, than both R&D employment and the number of patents. Contrary to most empirical research in this field, the analyses carried out in the present paper indicate that inventive activity seems to increase more than proportionately with firm size.     

Patent Statistics as an Innovation Indicator? Evidence from the Hard Disk Drive Industry

We assess the usefulness of patent statistics as an indicator of innovation, using a direct measure of innovation in the hard disk industry (1976–1998). Three findings emerge: (i) patents “predict” innovations better than a random guess, and a simple refinement makes them more useful; (ii) conditional on actually innovating, conglomerates and larger firms patent more than specialised startups and smaller firms; and (iii) patent reforms seem to make the patent–innovation relationship nonstationary. These results suggest that researchers should use caution when comparing patents of different types of firms and across years.     

Attenuation bias when measuring inventive performance

Most previous results on determinants of inventive performance are biased because inventive performance is measured with error. This measurement error causes attenuation bias. More specifically, for example age and education as drivers of patenting success have biased coefficients and too high standard errors when inventive performance is measured in short observation periods. The reason for measurement errors in inventive performance is that patents are typically applied for in waves.     

Embracing invention similarity for the measurement of vertically overlapping claims

ABSTRACT

Clear and well-defined patent rights can incentivize innovation by granting monopoly rights to the inventor for a limited period of time in exchange for public disclosure of the invention. However, with cumulative innovation, when a product draws from intellectual property held across multiple firms (including fragmented intellectual property or patent thickets), contracting failures may lead to suboptimal economic outcomes. However, an alternative theory, developed by a variety of scholars, contends that patent thickets have a more ambiguous effect. Researchers have developed several measures to gauge the extent and impact of cumulative innovation and the various channels of patent thickets. This paper contends that mis-measurement may contribute to the incoherence and overall lack of consensus within the patent thickets literature. Specifically, the literature is missing a precise measure of vertically overlapping claims. We propose a new measure of vertically overlapping claims that incorporates invention similarity to more precisely identify inventive overlap. The measure defined in this paper will enable more accurate measurement, and allow for novel economic research on cumulative innovation, fragmentation in intellectual property, and patent thickets within and across all patent jurisdictions.     

The effect of infrastructure on invention : Innovative capacity and the dynamics of public construction investment

The association between public infrastructural investment and invention is explored in this study, analyzing expenditure and patenting trends and cycles over much of the 20th century. First, innovative capacity, an endogenous indicator of US innovation potential based on invention patent output, is conceptualized and discussed. A major shift in invention modes is shown to have occured over seven decades (1920–1989) as corporate, rather than individual, invention became the most important national source of innovative capacity. The support of public infrastructure for invention is then analyzed, considering its most important characteristics and supportive functions, and its expenditure patterns over seven decades. The analysis of the infrastructural investment and the innovative capacity age cycle dynamics reveals a remarkable association between educational infrastructure construction and both aggregate and corporate innovative capacity. Time-series statistical analyses provide further insights on the effects of infrastructural investment on invention, showing that corporate patenting tends to benefit more from public infrastructural construction and that educational infrastructure expenditures provide a stronger association with both aggregate and corporate inventive performance.     

The impact of the corporate income tax: evidence from state organizational form data

By taxing the income of corporate firms at a different rate than non-corporate firms, taxes can play an important role in a firm's choice of organizational form. The sensitivity of the organizational form decision to tax rates provides a key indicator of the distortion created by the corporate income tax. This paper uses new cross-sectional data on organizational form choices across states compiled in the Census of Retail Trade to estimate this sensitivity. The results document a significant impact of the relative taxation of corporate to personal income on the share of real economic activity that is done by corporations and that the impact is many times larger than has been found in the previous empirical literature based on time-series data. The results show little impact, however, on the actual operations of firms such as their labor intensity, wages and the like. They do indicate that firms are able to exploit the progressivity of the corporate income tax system by dividing into numerous firms.     

Information technology innovation in India: The top 100 IT firms

Patents serve as an indicator of the innovation capability of countries, industries, or firms. Many Indian firms are in a transition to move from labor intensive segments to areas with higher value added which has been reflected in this research. The purpose of this study is to analyze patents issued during the period of 1997–2009 from the European Patent Office database and the United States Patent and Trademark Office database from the top one hundred Indian information technology firms. This study represents a novel empirical look at information technology industry innovations in India. A comprehensive set of statistical patent analyses are presented to provide practitioners with valuable knowledge to assist in business strategic planning.     

Knowledge resources and innovation performance: the mediation of innovation capability moderated by management commitment

This paper examines the process that links knowledge resources to innovation performance. We propose that this relationship is mediated by innovation capability and that management commitment moderates this mediation effect. To measure innovation performance, we create an indicator that summarises the impact of innovation activities on products, processes and sustainability. The sample comprises 9432 firms in different sectors included in the Community Innovation Survey (CIS). The results confirm that knowledge resources not only have a direct positive effect on innovation performance but also an indirect effect by improving the firm's innovation capability. We also confirm the moderating role of management commitment, but with limitations. This research, therefore, throws light on how firms can leverage their knowledge resources to gain a competitive advantage based on innovation.     

Using patent analysis to establish technological position: Two different strategic approaches

Discussions on business strategy formation in the past 50 years can be separated into two categories: the inside-out and the outside-in approach. Technology is a critical factor when manager formulate their business strategy, and patents have served as an important indicator of technology. A patent portfolio can be used to understand the capabilities of a firm, as an inside resource pattern; and the patent citation of firms can be used to find the relationship of a firm, as an outside dependency. This study uses patent information to establish an effective model for the technological position of business methods. The 5 by 6 matrix was generated and four situations between firms were induced. Researchers and managers can use that matrix and situations to recognize the real competitors or cooperators, and formulate the technological strategies which include competition, cooperation, or complementary cooperation.

Strategic alliances and internationalisation in the aircraft manufacturing industry

Based on an indicator measuring the technological level of aircraft, this paper shows that in the aircraft industry, firms are obliged to deal not only with high technological barriers, but growing financial and market barriers, too. In order to reduce these, a complex network of relationships has developed over time. This network involves both main firms belonging to the world oligopoly and firms capable of offering specialised technology and/or a potential broadening of the market. The result is a worldwide production organisation. This paper highlights the fact that the aircraft industry is undergoing a global reorganisation featuring an integration process where six groups (two in Europe and four in the United States) have come to the fore. In the future, it will be possible to imagine new forms of co-operation between the emerging European and American groups.     

A Method for Transitive and Additive Multilateral Comparisons: A Transitive Bennet Indicator

It is shown how the Bennet indicator (or ``index') can be made transitive. This is particular useful for making consistent (profit, cost, price, quantity) comparisons between firms when there are more than two firms and/or more than two periods. The method is given both statistical and economic justifications.     

Corporate governance,environmental regulations,and technological change

This paper investigates the relationship between environmental regulations and innovation by focusing on the automobile industry in a cross-country setting. We provide empirical evidence that the presence of agency problems mitigates the negative effects of environmental regulations on overall R&D activity, which leads to full compensation when the degree of agency problems is sufficiently high. Guiding our empirical analysis, we provide a general model consistent with the structure of existing ownership data. Specifically, we model ownership structure as a combination of two extreme corporate governance types. On the one extreme there are profit maximizers, and on the other extreme there are managers who are only concerned with their private benefits. The model leads to a simple country level ownership indicator and shows that if an economy is dominated by firms with higher agency problems, then pollution tax might even increase overall R&D, while reducing pollution. According to our estimations, such an outcome is possible only for out-of-sample values of the ownership indicator, where the degree of agency problems is extremely high.

Regional variation in the capital structure adjustment speed of listed firms: Evidence from China

This paper investigates whether in China, a country large in size, geographically diverse and imbalanced in regional economic development, variation in firm capital structure¹ is systematically related to regional economic environment. In addition, we examine whether during macroeconomic recovery there is significant difference in the speed of adjustment in capital structure of firms located in different regions. The empirical analyses are based on 783 firms listed on Shanghai and Shenzhen Stock Exchanges during a sample period of year 2000 through 2014. Using GMM and Logit QMLE, we found strong evidence that the regional variation in the capital structure of listed firms is linked to growth indicator (the Market-to-Book value, MB), EBIT ratio, size of the firm and tangible assets (the value of Net Property, Plant and Equipment, PPE). In the process of economic recovery, there was apparent regional variation in the speed of adjustment in capital structure, i.e. the fastest adjustment in capital structure was found in East China while that of West China followed and that of Mid China the slowest, that is to say within a given period the leverage ratio of listed firms in East China rises or falls faster than in the other two regions.     

Evaluating the Relative Innovative Position of European Union Member Countries: An Empirical Analysis

This paper aims to provide empirical evidence about the relative positions of European Union member states on innovation and, more specifically, on innovation in manufacturing. These positions were obtained from the aggregation of different innovation variables using the principal component analysis. We do not provide, from the statistical viewpoint, a synthetic indicator, even if, from the economic perspective, the information we obtained was similar to what such an indicator would provide. Our unit of analysis is the sector in each country, what we will term ‘country‐sector’, covering both innovative and non‐innovative firms.     

Broadband connected employees and labour productivity: a comparative analysis of 14 European countries based on distributed Microdata access

In this study, the association between information and communication technology (ICT) intensity in firms and labour productivity is explored across 14 European countries for the years 2001–2010. ICT intensity is approximated by the proportion of broadband internet-enabled employees, a novel indicator measuring not only adoption but also diffusion within and among firms. Data have been retrieved by means of the distributed microdata approach (DMD) from registers on business, trade and education as well as from surveys on production, ICT usage and innovation activities in firms held at the national statistical offices. This pioneering approach allows access to otherwise confidential linked firm-level information in dimensions not earlier available. Pooled OLS estimations based on approximately 400,000 observations in harmonised and representative datasets show that in a majority of countries there is a significant and positive relationship between the proportion of broadband internet-enabled employees and labour productivity in firms. However, the strength of the relationship varies across countries and industries. Manufacturing firms receive 50% larger estimates than the services firms, while the latter instead experience the positive association more frequently.
