Related variety and firm heterogeneity. What really matters for short-run firm growth?

ABSTRACT

In recent years, two concepts have become key elements in economic geography: related variety and firm heterogeneity. The first one predicts that knowledge spillovers within a region/local system occur among firms operating in ‘different but related’ sectors. The second one assumes that knowledge spillovers can occur among ‘different’ firms belonging to the same localised sector/industrial cluster. Using a sample of 27,817 Italian manufacturing firms observed during the period 2010–2013, this paper analyses the role played by related variety and within-sector firm heterogeneity on short-run employment growth. The results suggest that both related variety and within-sector firm heterogeneity have a positive effect, although the latter has a higher impact than the former. These results confirm the role played by related variety, but identify firm heterogeneity as a potential additional source of local knowledge spillovers.     

Patterns of corporate governance and technical efficiency in Italian manufacturing

The purpose of this paper is to analyse the relationship between the corporate governance system and technical efficiency in Italian manufacturing. We use a non‐parametric frontier technique (DEA) to derive technical efficiency measures for a sample of Italian firms taken from nine manufacturing industries. These measures are then related to the characteristics of the corporate governance system. Two of these characteristics turn out to have a positive impact on technical efficiency: the percentage of the company shares owned by the largest shareholder and the fact that a firm belongs to a pyramidal group. Interestingly, a trade‐off emerges between these influences, in the sense that one is stronger in industries where the other is weaker. Copyright © 2007 John Wiley & Sons, Ltd.

Competitive priorities and managerial performance: a taxonomy of small manufacturers

Much of the research in manufacturing strategy has focused on specific relationships between a few constructs, with relatively little emphasis on typologies and taxonomies [Bozarth, C., McDermott, C., 1998. Configurations in manufacturing strategy: a review and directions for future research. Journal of Operations Management 16 (4) 427–439]. Using data from 196 respondents in 98 manufacturing units, this study develops a taxonomy of small manufacturers based on their emphasis on several competitive priorities. The annual sales for 64% of the participating units in this study are below US$50 million, which is on the lower side as compared to other studies in this area [cf., Miller, J.G., Roth, A.V., 1994. A taxonomy of manufacturing strategies. Management Science 40 (3) 285–304]. The study findings indicate that different groups of manufacturers — Do All, Speedy Conformers, Efficient Conformers, and Starters — emphasize different sets of competitive priorities, even within the same industry. Further, the Do All types, who emphasize all four competitive priorities, seem to perform better on customer satisfaction than their counterparts in the Starters group. The above findings lend support to the sandcone model but contradict the traditional trade-off model.     

Firm turnover and productivity differentials in Ethiopian manufacturing

Are the forces of market selection at work in Africa? How successful are markets in these economies in sorting out firms on an efficiency basis following the sequence of reforms to liberalize and particularly to transform some of the previous command economies to market oriented ones? What is the pattern of entry and exit in the manufacturing sector and how does it affect industry productivity growth? This study examines these issues using firm-level industrial census data from the Ethiopian manufacturing sector. It is the first attempt to analyze firm turnover and productivity differentials using industrial census data in sub-Saharan Africa. The Ethiopian manufacturing sector exhibits a high firm turnover rate that declines with size. Exit is particularly high among new entrants; 60% exit within the first 3 years in business. Our study consistently shows a significant difference in productivity across different groups of firms, which is reflected in a turnover pattern where the less productive exit while firms with better productivity survive. We also found higher aggregate productivity growth over the sample period, mainly driven by firm turnover.     

Environmental Kuznets Curves for Air Pollutant Emissions in Italy: Evidence from Environmental Accounts (NAMEA) Panel Data

This paper provides new empirical evidence on delinking and Environmental Kuznets Curves (EKC) for greenhouse gases and other air pollutant emissions in Italy. A panel dataset based on the Italian NAMEA (National Accounts Matrix including Environmental Accounts) for 1990–2001 is analysed. The highly disaggregated dataset (29 production branches, 12 years and nine air emissions) provides a large heterogeneity and can help to overcome the shortcomings of the usual approach to EKC based on cross-country data. Both value added and capital stock per employee are used as alternative drivers for analysing sectoral NAMEA emissions. Trade openness at the same sectoral level is also introduced among the covariates. We find mixed evidence supporting the EKC hypothesis. The analysis of NAMEA-based data shows that some of the pollutants such as two greenhouse gases (CO₂ and CH₄) and CO, produce inverted U-shaped curves with coherent within-range turning points. Other pollutants (SO_X, NO_X, PM₁₀) show a monotonic or even N-shaped relationship. Macro sectoral disaggregated analysis highlights that the aggregated outcome should hide some heterogeneity across different groups of production branches (industry, manufacturing only and services). Services tend to present an inverted N-shape in most cases. Manufacturing industry shows a mix of inverted U and N-shapes, depending on the emission considered. The same is true for industry (all industries, not only manufacturing): although a turning point has been experienced, N-shapes may lead to increased emissions with respect to very high levels of the economic driver. In general, EKC evidence is more pronounced for greenhouse gases. The results suggest that analysis at macro sector (whole industry, manufacturing only and services) can be the most promising approach to future research on EKC.     

Entrepreneurship and market size. The case of young college graduates in Italy

We analyse empirically the effects of urbanization on Italian college graduates' work possibilities as entrepreneurs three years after graduation. We find that doubling the province of work's population density reduces the chances of being an entrepreneur by 2–3 percentage points. This result holds after controlling for regional fixed effects and is robust to instrumenting urbanization. Provinces' competition, urban amenities and dis-amenities, cost of labour, earning differentials between employees and self-employed workers, unemployment rates and value added per capita account for more than half of the negative urbanization penalty. Our result cannot be entirely explained by the presence of negative differentials in returns to entrepreneurship between the most and the least densely populated areas. In fact, as long as they succeed in entering the most densely populated markets, young entrepreneurs are able to reap-off the benefits of urbanization externalities: the elasticity of entrepreneurs' net monthly earnings with respect to population density is 0.02–0.03.     

Experimenting with Supply Chain Learning (SCL): Supplier Diversity and Ethnic Minority Businesses

This paper reports on an innovative UK-based ‘Supply Chain Learning’ (SCL) initiative to encourage the corporate sector to consider supplier diversity in respect of ethnic minority businesses. This follows academic and policy interest in programmes to empower ethnic minority enterprises to achieve breakout to mainstream markets and business growth. The first phase of the initiative, entitled Supplier Development East Midlands (SDEM) is examined. By adopting an inter-organisational action learning approach, some of the key attributes of the programme are delineated, focusing on the recurrent action-reflection cycle taking place in a learning group comprising SDEM, LPOs (Large Purchasing Organisations) and small EMSs (Ethnic Minority Suppliers).     

Coevolution of Institutions and Corporations in Emerging Economies: How the Salim Group Morphed into an Institution of Suharto's Crony Regime

abstract We investigate whether large family groups in emerging economies can proactively change their environment. We use a coevolutionary approach, which accounts for the influence of context on the entrepreneur and for the freedom of the latter to modify it. We find that entrepreneurs can shape institutions to their advantage, illustrated by the Salim Group, which achieved growth by aligning with and influencing politicians, eventually ‘morphing into an institution’. We unravel unique coevolutionary patterns, which we use to extend existing theories. Our first contribution is to initiate a new line of inquiry in coevolution theory, focusing on individual companies coevolving with institutions. Secondly, we document factors that increase and decrease strategic choice for family groups in emerging economies. Thirdly, we find that the Salim Group became part of the crony Suharto regime. The group became both an institutional entrepreneur and an entrepreneurial institution, demonstrating that companies and institutions are not necessarily mutually exclusive.     

Regional Inequalities in Consumption Patterns: A Multilevel Approach to the Case of Italy

The main aim of this paper is to evaluate the disparities in the Italian regions on the demand side. In more detail, an attempt will be made to find if the consumption behaviour of Italian households is different in the regions. With this in mind, Istat's 2000 Italian Family Budget data set was analysed. The data in question, which were collected through a two‐stage sample over Italy's 20 regions, contains information regarding the expenses of approximately 23,000 households. In this analysis, both households and regions are considered as units: households are nested in the regions so that the basic data structure is hierarchical. In order to take this hierarchical structure into account, a multilevel model was used, making it possible for parameters to vary randomly from region to region. The model in question also made it possible to consider heterogeneity across different groups (regions), such as stochastic variation. First, regional inequalities were tested using a simple model in which households constituted the first level of analysis and were grouped according to their region (the second level). As a second step, and in order to investigate the interaction between geographical context and income distribution, another model was used. This was cross‐classified by income and regions. The most relevant results showed that there is wide fragmentation of consumption behaviour and, at the same time, various differentiated types of behaviour in the regions under analysis. These territorial differentials become clear from income class and items of consumption.     

Servitization: Disentangling the impact of service business model innovation on manufacturing firm performance

As manufacturing businesses operate in an ever more competitive, global economy where products are easily commoditized, innovating by adding services to the core product offering has become a popular strategy. Contrary to the economic benefits expected, recent findings pinpoint implementation hurdles that lead to a potential performance decline, the so-called ‘servitization paradox’. In this paper, we analyze this paradox by disentangling the value creation and value appropriation processes of 44 national subsidiaries of a global manufacturing firm turned product-service provider, in the 2001–2007 period. Our findings show that the firm under study is able to successfully transcend the inherent substitution of products by services and to enact complementary sales dynamics between the two activities. Moreover, labor-intensive services such as maintenance, which imply higher levels of customer proximity, further enhance product sales. Empirical results also reveal a positive yet non-linear relationship between the scale of service activities and profitability: while initial levels of servicing result in a steep increase in profitability, a period of relative decline is observed before the positive relationship between the scale of services and profitability re-emerges. These findings suggest the presence of initial short-term gains but also indicate the existence of a ‘profitability’ hurdle; profitable growth seems feasible only to the extent that investments in service capability are translated into economies of scale. In helping to clarify the performance implications of service innovation, our findings suggest pathways to sustainable growth through servitization for manufacturing firms.     

A micro-econometric analysis of the role of R&D spillovers using a nonlinear translog specification

This paper assesses the impact of Research and Development (R&D) spillovers on production for a panel of 1,203 Italian manufacturing firms over the period 1998–2003.The estimations are based on a nonlinear translog production function augmented by a measure of R&D spillovers which combines the geographical distance between firms, the technological similarity within each pair of firms and the technical efficiency of each firm. The estimation method takes into account the endogeneity of regressors and the potential sample selection issue regarding the decision by firms to invest in R&D. Results show that the translog production function is more suitable than the Cobb-Douglas for modelling firm behaviour and that returns to scale are increasing. Moreover, the internal and external stocks of technology exert a significant impact on firms’ production. Finally, it emerges that, for Italian manufacturing firms, R&D capital and R&D spillovers are highly substitutes.     

Statistical Inference under Symmetry

We explore the consequences of adjoining a symmetry group to a statistical model. Group actions are first induced on the sample space, and then on the parameter space. It is argued that the right invariant measure induced by the group on the parameter space is a natural non-informative prior for the parameters of the model. The permissible sub-parameters are introduced, i.e., the subparameters upon which group actions can be defined. Equivariant estimators are similarly defined. Orbits of the group are defined on the sample space and on the parameter space; in particular the group action is called transitive when there is only one orbit. Credibility sets and confidence sets are shown (under right invariant prior and assuming transitivity on the parameter space) to be equal when defined by permissible sub-parameters and constructed from equivariant estimators. The effect of different choices of transformation group is illustrated by examples, and properties of the orbits on the sample space and on the parameter space are discussed. It is argued that model reduction should be constrained to one or several orbits of the group. Using this and other natural criteria and concepts, among them concepts related to design of experiments under symmetry, leads to links towards chemometrical prediction methods and towards the foundation of quantum theory.

Cross-cultural analysis of the global mindset and the internationalization behavior of small firms

This research analyzes the influence of a global mindset on the internationalization behavior of Norwegian and Portuguese small firms. It specifically sets out to assess the role of global orientation of the entrepreneur and firm perspectives on the global market. Based on a sample of 354 small firms, we used structural equation modeling to conduct our analysis. The results show the differing importance of a range of factors in explaining global mindset in different contexts. The global mindset of Norwegian entrepreneurs conditions their behavior and international experience, while for Portuguese entrepreneurs it affects the cognitive domain and their technical expertise. Global mindset and global orientation have more relevant effects on the internationalization behavior of Norwegian firms than that of Portuguese firms.     

A bootstrap analysis to investigate the economic efficiency of the logistics industry in Italy*

As argued by literature and consultancy reports, logistics enhances both productivity and competitiveness of several manufacturing supply chains. The analysis of the efficiency trends of logistics providers may shed light on some relevant aspects that can impact on the competitiveness of national industrial systems. Thus, the paper focuses on the Italian logistics supply, shedding lights on the distribution of the efficiency level within the logistics sector and its causes. The analysis is based on a two-stage methodology aimed at estimating the Italian logistics firms’ efficiency and defining some characteristics impacting the efficiency level. At first, we implement a Data Envelopment Analysis model based on balance sheet data, for the period 2006–2012, then an econometric regression is performed in order to identify the effects of main companies’ characteristics on firms’ efficiency. According to our results, size and geographical location are two of the most impacting variables explaining the efficiency score of the Italian logistics providers.     

Whatever happened to the Quadro Fedele?

The English language version of the Fourth Directive included a general clause that the accounts of a company should give a true and fair view. The same article 2 (3) of the Italian version of the directive called for the accounts of a company to give a quadro fedele. Several years later the directive was incorporated into Italian law, but, departing from the term used in the Italian version, called instead for the accounts to give una rappresentazione veritiera e corretta. This paper shows that since it first appeared in Italian law in 1983 there has been no homogeneous understanding in Italy among legal experts as to the meaning of a quadro fedele and that it was ultimately replaced in the 1990s with the rappresentazione veritiera e corretta because it failed in the mind of the legislators to reproduce in Italian the perceived spirit of the British version.     

The negative influence of the entrepreneur’s level of higher education on the attractiveness of European SMEs as alliance partners in Brazil: the role of practical experience and international entrepreneurial orientation

Notwithstanding the contemporary relevance of alliance strategies for SME internationalisation, especially in the case of uncertain business environments, few studies have investigated human resource issues in the context of SMEs prior to alliance formation. Even more scarce are studies looking at the impact of a manager/entrepreneur’s characteristics on pre-alliance formation, despite recognition of the expected crucial role of the entrepreneur in this context and of the strong connection between an entrepreneur and their SME. Drawing on international entrepreneurship theory and empirical observations from an exploratory study, we propose a post hoc conceptual model. The exploratory empirical part of our study employs a sample of entrepreneurs from biotechnology SMEs in the United Kingdom and Germany intending to ally in a large emerging market (i.e. Brazil). Our empirical observations suggest an anomalous (at first glance) negative association between the entrepreneur’s level of higher education (a construct at the individual level) and the attractiveness of the SME as a partner firm vis-à-vis alliance formation (a construct at the firm level). Our post hoc model emphasises the role of practical experience and the corresponding levels of international entrepreneurial orientation as theorised variables mediating the observed empirical relationship. We develop theoretical propositions, and suggest practical implications and future research directions.
