Endogenous product versus process innovation and a firm’s propensity to export

This article provides an empirical analysis of the effects of new product versus process innovations on export propensity at the firm level. Product innovation is a key factor for successful market entry in models of creative destruction and Schumpeterian growth. Process innovation helps securing a firm’s market position given the characteristics of its product supply. Both modes of innovation are expected to raise a firm’s propensity to export. According to new trade theory, we conjecture that product innovation is relatively more important in that regard. We investigate these hypotheses in a rich survey panel data set with information about new innovations of either type. With a set of indicators regarding innovation motives and impediments and continuous variables at the firm and industry level at hand, we may determine the probability of launching new innovations and their impact on export propensity at the firm level through a double treatment approach.     

The nonlinear effects of firm size on innovation: an empirical investigation

ABSTRACT

In conventional studies, large firms tend to emphasize more on process innovation than product innovation. This paper explores factors that could indicate a distinct pattern of firms’ innovation-size relationship: threshold size that implies a positive effect of firm size on the probability of product innovation success; cannibalization effect that creates incentives for large firms to favor product innovations; and financial constraints that have differential effects given different firm sizes. A hypothesis about a non-monotonic relationship between the proportion of product innovation and firm size is tested with nonlinear and dynamic econometric models. For the large firms, empirical evidence shows product innovations result in an overall larger share of new products in total sales, relative to existing products in which process innovations are rooted.     

Innovation strategies,process and product innovations and growth: Firm-level evidence from Brazil

Using World Bank ICS 2000–2002 data from Brazilian manufacturing firms, this paper identifies innovation strategies of firms – in particular internal development (“technology make”) and external acquisition (“technology buy)” – and their effect on successful process and product innovations. It subsequently explores the importance of process and product innovations for firm growth. Successful process and product innovations occur mostly through “technology buy” (mostly through the purchase of machinery and equipment), either alone or in combination with a “technology make” strategy. The option of only relying on internal development is less successful. The results on firm growth indicate that innovative performance is an important driver for firm growth. It is particularly the combination of product and process innovations that significantly improves firm growth. Both innovation and growth performance are supported by access to finance. Skills of workforce and management matter, but not necessarily tertiary education levels. The impact of international linkages on innovative and growth performance is mixed.     

Diversification: a road to inefficiency in product innovations?

Motivated by recent empirical observations made in industries such as the automobile industry, this paper employs an agent-based industry simulation model to examine the strategic relationship between product diversification strategies and some aspects of the product innovation strategy of a single producer. In particular, it is established that an increase in the average degree of product diversification in an industry increases the incentive for a producer to reduce the time to market for innovations at the expense of product quality. However, if all firms adapt their strategies according to these incentives, this results in a severe loss of average firm profits in the industry and also to a reduction in consumer surplus. It is then studied how the strength of this dilemma depends on several parameters describing the market structure and patent policy.     

Technological innovation and the demand for labor by firms in expansion and recession

ABSTRACT

With firm data from the Spanish Community Innovation Survey (CIS) for the period 2003–2014, we find a positive and significant effect of innovation in the demand for labor when firms introduce product and process innovations in the same time period. The effect of innovation on the demand for labor is countercyclical, higher in the recession, after 2008, than in the expansion, before 2008, but the probability that firms innovate in product and process is counter-cyclical, i.e. lower in the recession. Altogether, the elasticity of the demand for labor to the probability that firms introduce product and process innovations remains stable throughout the sample period, at around 0.035. Innovation contributes to stabilize average employment during the cycle, more so when the innovation is in product, alone or together with process, than when it is only in process. These results are broadly consistent with product and process innovations shifting firms’ demand and production functions upwards, but differentially in expansions (less product market competition) than in contractions (more competition).     

Rapid Technology Change, ‘Technological Visions’, Corporate Organisation And Market Structure

This paper is a contribution to the analysis of how rapid technology change influences market structure. The paper uses a simple simulation model to explore the effects of four main factors on the development of market structure. These are: (1) the variance (or unpredictability) of the technology trajectory; (2) the speed with which the organisation's ‘technological vision’ adjusts to ongoing technological developments; (3) the absorptive capacity of each division in the multi-divisional firm to experience gained in other divisions; (4) the extent to which competence-destroying innovations generate greater cost penalties for the division of a multi-divisional firm than for a comparable mono-divisional firm. Simultion results are obtained for 100 technological trajectories, and a variety of parameterisations. While there is a tendency for noisier trajectories to disadvantage the larger multi-divisional firm, there are conditions under which such a firm benefits from a noisy technological environment. When competence-destorying innovations affect the division of a multi-divisional firm no worse than the comparable mono-divisional firm, the multi-divisional firm is not disproportionately affected by a noisy trajectory. It may, however, be seriously damaged by a slow adjustment of technological vision, especially when all scale economies are dynamic (rather than static). The simulations confirm that the absorptive capacity of each division to experience from others can be critical in determining the ultimate market structure. A brief empirical motivation for the model is offered by reference to some case studies of the semiconductor industry.     

BIG data – BIG gains? Understanding the link between big data analytics and innovation

ABSTRACT

This paper analyzes the relationship between firms' use of big data analytics and their innovative performance in terms of product innovations. Since big data technologies provide new data information practices, they create novel decision-making possibilities, which are widely believed to support firms' innovation process. Applying German firm-level data within a knowledge production function framework we find suggestive evidence that big data analytics is a relevant determinant for the likelihood of a firm becoming a product innovator as well as for the market success of product innovations. These results hold for the manufacturing as well as for the service sector but are contingent on firms' investment in IT-specific skills. Overall, the results support the view that big data analytics have the potential to enable innovation.     

Market Share, Market Value and Innovation in a Panel of British Manufacturing Firms

This paper examines the empirical relationship between technological innovations, market share and stock market value. New developments in the estimation of dynamic count data models are used to control for unobserved firm specific heterogeneity. We find a robust and positive effect of market share on observable headcounts of innovations and patents although increased product market competition in the industry tends to stimulate innovative activity. Furthermore, the impact of innovation on market value is larger for firms with higher market shares. We argue that our results are consistent with models where high market share firms have incentives to pre-emptively innovate.     

The product innovation process and GDP dynamics

In this paper, we explain GDP dynamics through an analysis of the forces that modify the structure of the economy. These forces are represented by the entry of new firms and product innovations. Our model is inspired by Bak’s sand pile model, and the entry of a new firm or innovation is comparable to dropping a grain of sand in Bak’s model. The resulting model involves the insights of both Keynes and Schumpeter. It could be defined as Keynesian because the aggregate output is demand driven. That said, the model can mainly be labeled as Schumpeterian for several reasons: (i) innovations have a key role, (ii) credit is involved in supporting the innovation process, (iii) innovations partially destroy old industries, and finally (iv) without innovations, the system gradually approaches its stationary state. In this simple model, the change in the number of sectors (products) of the economy is the decisive factor with the following results: (1) the aggregate production has an increasing trend; (2) fluctuations are asymmetric; (3) recessions have a “creative destruction” explanation; (4) “classical” cycles are gradually replaced by “growth” cycles.     

Market structure and market performance in E-commerce

We analyze the interaction between market structure and market performance and how it varies over the product cycle. To account for the potential endogeneity in this relation, we use an instrumental variable approach. We combine data from the largest Austrian online market for price comparisons with retail data on wholesale prices provided by a major hardware producer for consumer electronics. Our results show that instrumenting is important for estimating the empirical effect of competition on the markup of the price leader. One more firm in the market is associated with a reduction of the price leader׳s markup which is equivalent to competition between existing firms for an additional 3 weeks in the product life cycle. Our results support search theoretic models and contradict models of monopolistic competition. Moreover our results support the existence of price dynamics over the product cycle. They also highlight the substitutability between newly innovated and old expiring technologies and how it varies with respect to competitors׳ and own brand innovations.     

Corporate governance structure and product market competition

This article assesses the effects of the competitive structure of a product market on a firm’s corporate governance structure. Our model demonstrates that shareholders strategically determine the corporate governance structure, including the manager’s stock ownership and his controlling power over the firm, in order to maximize their utility in the product market competition. We find that the manager’s stock ownership is lower and his controlling power over the firm is higher when the firm’s product is more profitable or when competition within the product market is more severe. The inefficiency of the wealth transfer from shareholders to the manager also affects the corporate governance structure.     

R&D subsidies in a model of growth with dynamic market structure

This paper presents the effects of an R&D subsidy in a Schumpeterian general equilibrium model with rich industry dynamics. R&D subsidies raise the long-run growth rate, but they also raise the level of industry concentration. In the model firms compete for market share through process R&D endogenously determining the market structure within and across industries. Endogeneity of the market structure allows for analysis of changes in the moments of the firm size distribution in response to policy. R&D subsidies primarily benefit large incumbent firms who increase their innovation rates creating a greater technological barrier to entry. Concentration increases with fewer firms and a higher variance in the market shares. In general equilibrium, the greater distortions in the product market cause the wage rate to fall which leads to increased turnover rates. In addition, the analysis demonstrates that the model captures a large number of empirical regularities described in the industrial organization literature, but absent from most endogenous growth models. These features, such as entering firms are small relative to incumbents, the hazard rate of exit is negatively related to firm size, and large firms spend more on R&D than small firms play important roles in understanding the impact of R&D subsidies on the economy.     

Productivity, innovation and R&D: Micro evidence for Italy

By exploiting a rich firm level data-base, this paper presents novel empirical evidence on the effect of process and product innovations on productivity, as well as on the role played by R&D and fixed capital investment in enhancing the likelihood of introducing innovations at the firm level. Our results imply that process innovation has a large impact on productivity. Furthermore, R&D spending is strongly positively associated with the probability of introducing a new product, whereas fixed capital spending increases the likelihood of introducing a process innovation. The latter result might reflect the fact that new technologies are frequently embodied in new capital goods. However, the effect of fixed investment on the probability of introducing a process innovation is magnified by R&D spending internal to the firm. This implies that R&D can affect productivity growth by facilitating the absorption of new technologies.     

CHOICE OF PRODUCT TYPE BY STRATEGICALLY INTERDEPENDENT FIRMS

The paper analyses the degree of product differentiation between sigle product firms in alternative market equilibria. The equilibria are stable in the sense of Nash, and both non-cooperative and tacitly collusive market outcomesare identified. The basic model follows the 'address' aproach to product differentiation, and the firms' strategic variables are choice of product type and price charged. When all firms are non-cooperative, product gaps between firms are equal; but tacit collusion results in product gap variation between firms in Nash equilibrium. In all cases, profits for any firm are assumed to be proportional to the multiple of the product gaps between that firm and each of its two closest rivals.     

An empirical analysis of firm process and product patenting

This paper presents an empriical study of the determinants of firm patenting. Since industrial research and development (R&D) encompasses a variety of activities, this study distinguishes between patents on process innovations and patents on product innovations. The property rights provided by a patent may differ between process and product patents, which suggests that the determinants of process innovations and product innovations may difer as well.

Several recent studies have distinguished between research directed toward process innovations and research directed toward product innovations. Scherer (1983a) included measures of process R&D spending and product R&D spending in regressions for inter-industry differences in productivity growth. Link and Lunn (1984) found that the returns to process-related R&D activity exceed the returns to product-related R&D activity. Link (1982) found inter-firm differences in the allocation of R&D spending for process innovations and product innovations. Lunn (1986) found differences in the determinants, as well as the effects, of process patenting and product patenting at the industry level. This paper examines whether the determinants of product and process patenting differ at the firm level.     

企业规模异质性与产业集聚：来自中国制造业的证据

基于中国制造业数据,本文检验了企业规模异质性与制造业地理集中的互动联系。研究表明企业规模因素对制造业地理集中具有显著影响。按素密集度对制造业的分类回归进一步表明,上述影响存在行业差异：劳动力与资源密集型行业的相关性不稳健,但资本技术密集型行业的结果是稳健的。这意味着资本技术密集型行业的企业规模分布具有地理集中倾向：大市场集中分布了更多大规模企业。这一结论表明制造业集聚具有规模异质性：小规模企业通过集聚经济,促进生产率提高形成制造业集聚,大规模企业则通过集中分布在大市场而形成制造业集聚。另外,从制造业集聚的驱动力量看,制造业集聚的强化效应与地区异质因素两股力量都在推动制造业地理集中,由此可以判断制造业集中趋势还将持续。     

Incentives for input foreclosure

We analyze the incentives of a vertically integrated firm to foreclose downstream rivals in a model of upstream price competition between suppliers of only imperfectly substitutable inputs. Our main motivation is a critical assessment of common assertions that draw inferences from pre-merger observable variables to post-merger incentives to foreclose. In particular, we find that, contrary to some commonly expressed views, high margins on the downstream and low margins on the upstream market are not good predictors for the incentives of a newly integrated firm to foreclose rivals. Besides this contribution to policy, our model also extends existing results in the literature on vertical foreclosure through allowing for the interaction of product differentiation on the upstream and on the downstream market.     

Battle royal in biotechnology: R&D vs. product vs. process innovations

Companies regard innovation as a central element of their business. However, as not all innovation types are the same, the central question is: should their announcements bring about the same effect on performance? This article analyses potential differences in firm value derived from the innovation-type announcements ‘R&;D’, ‘product’, and ‘process’, made by intensive news-generating firms such as biotech companies. The empirical application shows a significantly positive reaction to innovation announcements, with the prospect of future innovation (‘R&;D’ investment announcements) having greater impact on firm value than ‘product’ and ‘process’ innovations. Firm experience also acts as a moderator in this innovation–performance relationship, which is particularly relevant for entrepreneurs who need to develop and send credible signals indicating the value of the firm's intangible assets to the market.     

The effect of mergers on the incentive to invest in cost-reducing innovations

Both mergers and innovation are central elements of a firm's competitive strategy. However, model-theoretical analysis of the merger-innovation link is sparse. The aim of this paper is to analyze the impact of mergers on innovative activities and product market competition in the context of incremental process innovations. Inefficiencies due to organizational problems of mergers are accounted for. We show that optimal investment strategies depend on the resulting market structure and differ significantly from insider to outsider. In our linear model mergers turn out to increase social surplus.
