Scale effects in endogenous growth theory: an error of aggregation not specification

Modern Schumpeterian growth theory focuses on the product line as the main locus of innovation and exploits endogenous product proliferation to sterilize the scale effect. The empirical core of this theory consists of two claims: (i) growth depends on average employment (i.e., employment per product line); (ii) average employment is scale invariant. We show that data on employment, R&D personnel, and the number of establishments in the US for the period 1964–2001 provide strong support for these claims. While employment and the total number of R&D workers increase with no apparent matching change in the long-run trend of productivity growth, employment and R&D employment per establishment exhibit no long-run trend. We also document that the number of establishments, employment and population exhibit a positive trend, while the ratio employment/establishment does not. Finally, we provide results of time series tests consistent with the predictions of these models.     

Perceptions of Industrial Design: The “Means” and the “Ends”

It is widely accepted that industrial design can play an important role in the development of innovative products, but integrating design‐thinking into new product development (NPD) is a challenge. This is because industrial designers have very different perspectives and goals than the other members of the NPD team, and this can lead to tensions. It has been postulated that the communications between NPD managers and industrial designers are made more difficult because each group uses very different language. This research made the first empirical investigation of the language used by designers and managers in describing “good” and “poor” industrial design. In‐depth interviews were conducted with a sample of 19 managers and industrial designers at five leading companies. Multiple sources of data were utilized, including the repertory grid technique to elicit the key attributes of design, from the perspective of managers and designers. Using a robust, systematic coding approach to maximize the validity and reliability of qualitative data analysis, it was established that managers and industrial designers do not use a completely different vocabulary as previously supposed. Rather, it was found that managers and industrial designers use some common terms augmented by additional terms that are specific to each group: managers are commercially orientated in the “ends” they want to achieve and designers perceive more antecedents (“means”) necessary to achieve their “ends”—iconic design. This research led to a grounded conceptual model of the role of design, as perceived by managers and industrial designers. The implications of the results achieved are wide: they indicate how managers and designers can interact more productively during NPD; they highlight the need for more research on the language of designers and managers; and they point to issues that need to be covered in the education of industrial designers. Finally, this work suggests how managers and designers can engage in a more fruitful dialogue that will help to make NPD more productive.     

News shocks and asset price volatility in general equilibrium

We study equity price volatility in general equilibrium with news shocks about future productivity and monetary policy. As West (1988) shows, in a partial equilibrium present discounted value model, news about the future cash flow reduces asset price volatility. We show that introducing news shocks in a canonical dynamic stochastic general equilibrium model may not reduce asset price volatility under plausible parameter assumptions. This is because, in general equilibrium, the asset cash flow itself may be affected by the introduction of news shocks. In addition, we show that neglecting to account for policy news shocks (e.g., policy announcements) can potentially bias empirical estimates of the impact of monetary policy shocks on asset prices.     

The process of supply network internationalisation

This paper explores the process that dynamically links the why's, how's and what's of supply network internationalisation. We propose a conceptual framework that adapts and extends the Uppsala internationalisation model and apply it to analyse nine case studies of Italian footwear and apparel companies involved in relocating some segments of their supply networks to Romania. Consistently with behavioural theories, our findings confirm that internationalisation is an incremental process in which firms gradually increase their international exposure and involvement. However, differently from the Uppsala establishment chain internationalisation model, our cross-case analysis suggests a different typology of supply network internationalisation processes: (1) traditional subcontracting, (2) co-ordinated subcontracting, and (3) supply system relocation. We discuss the theoretical and managerial implications of these findings and suggest directions for further research.     

Proactive and reactive views in the transition towards circular business models. A grounded study in the plastic packaging industry

This article contributes to the studies on the transition towards circular business models in incumbent entrepreneurial firms. The focus of our research is the plastic packaging industry, a paradigmatic case of firms with a high environmental impact who are currently under pressure to change their business models. Following a grounded theory approach, we conducted an exploratory research on five case studies, longitudinally analyzed over two years. The results of our research suggest that the circularity challenge raises dilemmas about how to interpret the transition to sustainability. On one hand, the transition may be interpreted in a reactive way, based on compliance to the law and the highest possible levels of continuity. On the other hand, the transition may be interpreted in a proactive way, based on radical experimentation and openness to change. Our results highlight that the reactive-proactive dilemma unfolds at three interconnected levels: the firm’s network (including the customers), the entrepreneur, and the organization. Our study also suggests that the entrepreneur is in a position to play a pivotal role in the multi-level adoption of a proactive (or reactive) view. More specifically, our longitudinal analysis suggests that if the effectiveness and impact of transition to circularity is to be maximized, then a multi-level proactive view of the circularity transition is key to transforming the three interconnected levels (network, entrepreneur, organization) into a proper, sustainability-oriented innovation ecosystem.

     

Classification of longitudinal career paths

The aim of the present article is to classify, in terms of contractual stability, the careers of the workers in a specified territorial context (Province of Milan-Italy), utilizing large administrative archives. The final goal is a synthetic clustering that identifies individuals in homogeneous groups regarding the longitudinal sequences of contractual typologies occurring in the evolution of vocational experiences during their career, identifying, on the one hand, the worker profiles that remain stable in each contractual typology and on the other hand, the profiles that improve or worsen contractual stability over time. Methodologically, our approach uses a combination of scaling methods to estimate stability scores of each contractual typology and Latent mixture models to cluster similar trajectories. Specifically, the scores of contractual stability were performed by Multidimensional Scaling with individual preferences, taking into account the ordinal nature of distances among contractual typologies and the heterogeneity factors of the subjects. Further, Latent Growth Mixture models, capitalizing the longitudinal property of data sequences, were proposed to identify distinctive, prototypical developmental trajectories of contractual stability within the analyzed population.     

Defying the ‘Juncker curse’: can reformist governments be re-elected?

European policy makers, notably in the euro area, seem to take for granted that the electorate will punish them for bold reform in product and labour markets. This may explain why progress in the euro area has been comparatively limited. This paper posits and, using a dataset for 21 OECD countries, shows that this fear of electoral backlashes is unfounded, provided that financial markets work well. The mechanisms involved are relatively straightforward: well functioning financial markets “bring forward” future yields of structural reform to the present, thus permitting to overcome possible short-run costs. As a result, the electorate tend to reward, not punish, reformist governments. This has important implications for the design of structural reform packages, with financial market reforms being an essential ingredient beside product and labour market reforms.

Transmitters and receivers' investment to avoid interference: Is there an optimal regime?

The management of interference has been, and still is, the main concern in spectrum policy. Historically, interference has been dealt with by heavy regulation under an administrative control regime. Over the last decades, a new approach has been put forward based on users' property rights, better able to cope with a rapidly changing technological environment. The issue of dealing with interference across bands, however, remains crucial: What obligations should be put on users so as to keep interference at a socially acceptable level? Also, given that some unwanted emissions are bound to occur, how can private parties be provided with the right incentives to invest in high-quality reception technology? This paper assesses how well different regulatory regimes can lead to efficient outcomes. It develops an economic model of spectrum interference and identifies the efficient solution. A regime where spectrum users have the power to enjoin intruding emissions beyond a predefined level (property rights protection) is compared with a regime where users are forced to bear with intruding emissions, but are entitled to economic compensation for the harm suffered (liability rules protection). The analysis suggests that different regimes may perform differently under different circumstances depending on the cause of interference and, critically, on whether the services are organised as an open- or a close-architecture system. This suggests that regulators should pay more attention to the specific features of the different bands, and that the appropriate spectrum management regime should be designed to recognise these differences.     

Output-inflation cycles in an economy with staggered wage setting

The question whether increased price flexibility is stabilizing in macromodels of the business cycle has been recently questioned by De Long and Summers (1986). The present paper is an attempt to reconsider the question by applying some methods from the theory of nonlinear dynamics, especially bifurcation theory, to the analysis of a dynamic model with sluggish price adjustment. It is argued that, when inflation plays a destabilizing role through the Mundell effect, a stable closed orbit representing the perfect-foresight dynamics of the output-inflation pair may appear in the vicinity of a stationary state. Moreover, bifurcation theory is applied to find analytical results about the relation between the amplitude of the cycles and the ‘degree’ of flexibility of prices. This relation is shown to be positive in a variety of cases.     

Signaling Strategies for Innovative Design: A Study on Design Tradition and Expert Attention

There is increasing acknowledgement that innovative product design has a positive effect on financial performance. However, innovative design may require specific efforts to aid interpretation and appreciation by the market. So far, little is known about how companies can enhance their chances of success when introducing innovative designs. This study contributes to the development of this area of research. Drawing on signaling theory, it examines the role of two types of signals that may act as enablers for market acceptance of innovative design: adherence to a national design tradition, and attention from experts and specialized media. Using data collected from Danish design‐intensive companies, findings show that design innovativeness has a positive impact on financial performance. The analyses demonstrate that the effect is reinforced if a novel design adheres to a national design tradition. In addition, novel designs will be more positively accepted if they receive attention from design experts and attract media coverage. Research also contributes to signaling theory, as it shows how intrinsic—design innovativeness and adherence to a design tradition—and extrinsic—expert and media attention—cues interact and influence financial performance. The paper concludes by discussing managerial implications, particularly in relation to the new product development process and the role of design, and by suggesting avenues for further research.
