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.     

IS THERE A CURSE OF RELOCATION? ANALYSING THE CAUSAL LINK BETWEEN OFFSHORING AND THE INNOVATION PERFORMANCE OF (SMALL) FIRMS

We analyse the empirical link between offshoring activities and different dimensions of innovation performance at the firm‐level. In order to identify causal effects running from offshoring to innovation, we use a quasi‐experimental comparison group approach by means of (conditional) difference‐in‐difference estimations applied to German establishment‐level data for firms that conducted offshoring activities in the period 2007–13. We find that the international relocation of business functions has a negative impact on the firms’ propensity to be innovative in terms of product and process innovations as well as product improvements. While for larger firms the reduction in process innovations is most striking, potentially due to a lack of resources, stagnation in expertise and a reduction in intra‐organizational learning‐by‐doing associated with the relocation of some business activities, for small and medium‐sized enterprises we particularly observe a reduction in product innovations after the offshoring activity has taken place. When interpreting this ‘pessimistic’ picture on the link between offshoring and the innovation performance of firms, the reader should note that our findings for German establishments have to be assessed through the lens of a global economy in economic recession after 2008, which may have intensified the negative impact of offshoring on the firms’ innovation performance.     

Innovation strategies and firm performance: Simple or complex strategies?

This paper analyzes the effect of various innovation strategies (ISs) of firms on their future performance, captured by labor productivity. Using five waves of the Community Innovation Survey in Sweden, we have traced the innovative behavior of firms over a decade, that is, from 2002 to 2012. We defined ISs to be either simple or complex (in various degrees). We call an IS a simple IS when firms engage in only one of the four types of Schumpeterian innovations, that is, product, process, marketing, or organizational, while a complex IS is when firms simultaneously engage in more than one type. The main findings indicate that those firms that choose and afford to have complex ISs are better off in terms of their future productivity in comparison with those firms that choose not to innovative (base group) and also in comparison with those firms that choose simple ISs. The results are mostly robust for those complex innovators that have a higher degree of complexity and also keep the balance between technological (product and process) and non-technological (organizational and marketing) innovations.     

A Microeconometric note on product innovation and product innovation advertising

This paper seeks to explain why more than half of the German service sector firms that introduce a product innovations do not advertise their new or markedly improved product. One part of the explanation is that they do not need to advertise because they are closely related to their customers anyway, and another part of the explanation is that product innovation and product innovation advertising are strategic substitutes.     

Persistence and economic effects of technological innovations: a dynamic and sequential analysis of Uruguayan manufacturing firms

This paper analyzes the long-term relationship between research and development (R&D), innovations and productivity in 400 Uruguayan manufacturing firms during the period 2001–2009 based on a modified version of the structural model of Crepon, Duguet and Mairesse. The paper also analyzes thoroughly the decision of these firms to engage in R&D activities by using a novel categorical dependent variable, which takes three values: non-performance R&D activities, occasional performance or continuous performance over the period. Furthermore, the study investigates whether these manufacturing ?rms innovate persistently or discontinuously over the period. The results suggest a positive link between the intensity of R&D activities and the generation of product and process innovations. They also indicate that innovation probability is temporally persistent at the ?rm-level only for product innovations. Finally, the empirical findings reveal that these technological innovations have a positive effect on firm’s productivity.     

Disentangling the effects of process and product innovation on cost and demand

ABSTRACT

We explore in this note different structural models of the impact of process and product innovation on firms' demand and production cost functions. We find that the introduction of process and product innovations affects them differently as could be expected. Both product and process innovation shift forward the demand for the products of the firm. Process innovation reduces production marginal cost, but not always. A possibility, that we cannot prove or reject with the current specification of our models and available data, is that process innovation associated with product innovation raise marginal cost. Interestingly, we also find that advertising significantly augments demand but does not affect production marginal cost. To obtain broader conclusions, richer data will be needed allowing an enlargement of the model, in which process and product innovations could be specified distinctively and well identified.     

Determinants of innovation behaviour and investment estimates for west-german manufacturing firms

In this paper, the determinants of innovation behaviour and investment are explored with a large micro-data panel from West-German manufacturing firms. The estimates are discussed within a microeconomic model with monopolistic competition, demand uncertainty and a delayed adjustment of capacities and the production technology. The estimates reveal positive firm-size effects which hint towards scale economies associated with innovations. Market power promotes innovations but not investment, and exporters innovate more but exhibit less investment expenditures. Finally, excess demand promotes innovations. This indicates a complementarity of innovations and investment and hints towards permanent productivity effects of temporary demand shocks.     

Environmental Innovations and Firm Profitability: Unmasking the Porter Hypothesis

We examine impacts of different types of environmental innovations on firm profits. Following Porter’s (Sci Am 264(4):168, 1991) hypothesis that environmental regulation can improve firms’ competitiveness, we distinguish between regulation-induced and voluntary environmental innovations. We find that innovations which do not improve firms’ resource efficiency do not provide positive returns to profitability. However, innovations that increase a firm’s resource efficiency in terms of material or energy consumption per unit of output have a positive impact on profitability. This positive result holds for both regulation-induced and voluntary innovations, although the effect is greater for regulation-driven innovation. We conclude that the Porter hypothesis does not hold in general for its “strong” version, but depends on the type of environmental innovation. Our findings rest on firm-level data from the German part of the Community Innovation Survey 2008 (CIS 2008).

Innovation and productivity in the food vs. the high-tech manufacturing sector

ABSTRACT

The food sector is considered a mature industry characterized by low research and development (R&D) intensity. Nevertheless, food companies face numerous challenges and cannot do without innovation activity if they want to keep their competitiveness. In this study, we examine the impact of innovation on labor productivity in European food companies and compare it to results for firms operating in high-tech sectors. The central motivation of our study is that the low R&D intensity observed in the food sector should be mirrored in different productivity effects of innovation when compared to the high-tech sector. We use microdata from the European Union's ‘Community Innovation Survey’ (CIS) and apply an endogeneity-robust multi-stage model that has been applied by various recent studies. Our results point out major differences between the examined subsectors. While we find strong positive effects of innovation on labor productivity for food firms, we find insignificant effects in the high-tech sector. This might suggest that the returns to innovation might be best evaluated separately by sector rather than for the manufacturing sector as a whole.     

Succeeding in innovation: key insights on the role of R&D and technological acquisition drawn from company data

This paper discusses the relationship between a company’s investment in innovation and its success in introducing new product and/or process innovations. In doing so, this analysis departs from the standard approach which puts forward a homogenous R&D-based knowledge production function by introducing different types of innovation investments (R&D and technology acquisition) for different sets of companies. Using the Community Innovation Survey (CIS) dataset comprising more than 3,000 Italian manufacturing companies, the econometric analysis adopts a set of techniques which allows to control for the sample selection, endogeneity and simultaneity problems which arise when dealing with CIS data. The main findings are summarised as follows: (1) beyond the acknowledged effect of R&D in increasing the probability of success of product innovation, a larger-than-expected role is played by technology acquisition in the innovation process; (2) the relative importance of R&D and technology acquisition varies significantly across different types of companies where crucial dimensions of analysis are company size and the technological domain of a sector.     

Persistence of product innovation: comparing breakthrough and incremental product innovation

In this paper we examine whether and to what extent breakthrough and incremental product innovation is persistent at the firm level. Drawing on a panel database created from the Community Innovation Survey (CIS) we find that lagged breakthrough product innovation ‘new to the market’, has a significant and positive influence on firms’ ability to develop current breakthrough innovation, while this is not the case for incremental-product innovation ‘only new to the firm’. Our findings show that the dynamics of innovation persistence differ across types of (product) innovations.     

Stochastic innovation and product market organization

Summary This paper analyzes how different types of product market organization affect firms' R&D investments in a stochastic innovation framework. Product market competition determines payoffs to successful and unsuccessful firms. Restrictions on the research project success probability distribution are identified that yield an invariance result for expenditure per R&D project. The impact of the number of firms (n) on the amount of market R&D is shown to be sensitive to product market organization. For a major process innovation, firms undertake more R&D projects under Cournot product market competition than under Bertrand competition, forn sufficiently large. A numerical example is used to illustrate welfare tradeoffs.Tom Lyon, Herman Quirmbach, Ferenc Szidarovszky, Mark Walker and two anonymous referees gave us helpful comments and suggestions on prior versions of this paper. Lucy Atkinson provided expert research assistance on numerical computations. Special thanks to Ted Bergstrom who gave us valuable suggestions about the first proposition.     

Beyond product innovation: deciphering process-oriented innovators,complementarities and performance effects

Relatively little attention has been paid to the understanding of process innovation, compared to the well-researched product innovation. This paper contributes to improve our understanding of process innovation and its specific process capabilities and performance by exploring, across many industries, 4,608 process-oriented innovators. Process innovation is defined as adoption of technologically new or significantly improved production methods, including changes in equipment, organisation or methods of product delivery. Process-oriented innovators or process seekers are those firms which usually only introduce process innovation, and no product innovation. These have received less attention by scholars. Results show that process innovation without also organisational innovation complements constrains innovative performance. Complex process-based innovation complementarities result from the simultaneous development and integration of new machinery and organisational innovations.     

The challenge to china’s enterprises from increasing labor costs: the product quality perspective

ABSTRACT

Using China Employer–Employee Survey data, this paper investigates the possible heterogeneous results of increasing labor costs of different firms. The paper finds that, unskilled labors have a higher wage growth rate than the skilled labor. Firms with higher product quality employ more skilled labor, and thus are less affected by the increasing labor costs. On the other hand, firms with higher product quality have less elastic demand, which makes it possible for them to increase their prices without demand decreasing. The conclusions are well supported by the data. Therefore, we should treat the challenge of increasing labor cost in a new way. The real challenge of increasing labor cost is greater for low-quality firms. The empirical results suggest that some of the low-quality firms should upgrade their quality to a higher level to offset their labor cost increase.

Does more competition increase business-level innovation? Evidence from domestically focused firms in emerging economies

This paper explores the relationship between the level of competition and innovation output for domestically focused businesses in emerging economies in Central and Eastern Europe and Central Asia. It uses survey data from 5054 businesses from the fifth Business Environment and Enterprise Performance Survey. A multivariate probit estimation of the likelihood of different innovation types finds that higher levels of competition are associated with greater likelihood of innovation, but this rises at a decreasing rate as competitor numbers grow. Also, firms operating in economies where competition policy is more effectively enforced are more likely to innovate. However, there is a point where ‘too much’ competition leads to less innovation – suggesting a tipping point effect. This suggests that policies to maximise competition, as measured by number of competitors, may not be optimal for promoting innovation in emerging economies. This requires a need for more nuanced competition policy approaches. The paper also finds that businesses relying on local markets are significantly less likely to introduce innovations than businesses trading domestically outside their local area, but increased competition in local markets increases the likelihood of businesses introducing product innovation. This points to a local rivalry effect.     

Firm size and types of innovation

We propose a general theory of innovation that illustrates the relative benefits of performing process versus product R&D when firm size is endogenous. A firm's size, scope, and R&D portfolio are shown to reflect the same underlying characteristic of the firm, namely manufacturing efficiency. We demonstrate that efficient firms become larger, have greater scope, and perform more of both process and product R&D. In light of decreasing returns to R&D, this implies small firms obtain more product innovations per dollar of R&D than large firms, which is consistent with evidence we present that small firms are more innovative than large firms as they obtain more patent counts and citations per dollar of R&D.     

Economic Integration,Process and Product Innovation,and Relative Skill Demand

The interaction between economic integration, product and process innovation, and relative skill demand is analyzed in a model of international oligopoly. Lower trading barriers increase the degree of foreign competition. The competing enterprises respond by investing more aggressively in lowering marginal costs of production. Moreover, firms reduce the substitutability of their products through additional investment in product innovation. The paper also shows that the relative demand for skilled workers may increase as a result.     

Patterns of innovation diffusion and technological competition in Portuguese manufacturing and service industries

This article uses data from the Portuguese Community Innovation Survey (CIS III) to analyse the inter‐industry heterogeneity in the diffusion of innovations and level of technological competition in Portuguese manufacturing and service industries. The industries are classified with reference to the relationship between the level of participation in innovation and the strategies of innovative firms. Methods of multivariate statistics are used to synthesize the data and to group the observations into subsets. Four distinctive innovation patterns are identified, defined along the following dimensions: output‐orientation of innovation, importance of disembodied innovation, role of technologically advanced innovation and level of innovation opportunities. It is also found that high levels of technological competition tend to occur in sectors with relatively low dimension, productivity and overall investment.
