What do firms know? What do they produce? A new look at the relationship between patenting profiles and patterns of product diversification

In this work, we analyze the relationship between the patterns of firm diversification, if any, across product lines and across bodies of innovative knowledge, proxied by the patent classes where the firm is present. Putting it more emphatically, we investigate the relationship between “what a firm does” and “what a firm knows.” Using a newly developed dataset matching information on patents and products at the firm level, we provide evidence concerning firms’ technological and product scope, their relationships, the size-scaling and coherence properties of diversification itself. Our analysis shows that typically firms are much more diversified in terms of products than in terms of technologies, with their main products more related to the exploitation of their innovative knowledge. The scaling properties show that the number of products and technologies increases log-linearly with firm size. And the directions of diversification themselves display coherence between neighboring activities also at relatively high degrees of diversification. These findings are well in tune with a capability-based theory of the firm.     

Firm Recruitment Behaviour: Sequential or Non‐sequential Search?

In the extensive job search literature, studies assume either sequential or non‐sequential search. This article introduces a novel method to test the hypothesis that firms search sequentially based on the relationship between the number of rejected job applicants and the number of filled vacancies. We distinguish between ten different search methods. For most search methods, including methods that rely on social networks and temporary help agencies, we find that sequential search cannot be rejected. However, when firms use advertising or public/private employment agencies, sequential search is rejected. Hence, we find that both forms of search are relevant for our understanding of the labour market. Further, the form of search is closely related to the search method used.     

Determinants of the growth aspiration: a quantitative study of Venezuelan entrepreneurs

The article examines the determinants of the growth aspiration of Venezuelan entrepreneurs. We use the GEM database and build an econometric model based on a set of exogenous variables grouped into three large categories: contextual or environmental factors, individual factors and business variables. Given the Venezuelan specific characteristics, we place a particular focus on understanding the differences between entrepreneurs belonging or not to the BoP. The primary findings of this work are the identification of the variables that explain growth aspiration, namely, belonging to the BoP, gender, education, motivation and years of study and some additional variables where individual factors interact with the contextual factor BoP. The second finding is that there are significant differences for the entrepreneurs belonging and not belonging to the BoP, with a threshold where the entrepreneurs of the BoP become averse to continuing to aspire to growth. Practical and policy implications are elaborated with the results.     

The strategic role of quality in small size firms

It is often claimed that, especially in mature industries, European firms can compete against low-cost NICs firms only if they are able to implement quality based strategies. The emphasis on the strategic role of quality, however, often leads to underestimate the extent of organizational and economic efforts, needed to turn quality from a potential opportunity into a real advantage. The lack of a thorough comprehension of the requirements of a quality based strategy can question the effectiveness of the investments some firms plan to improve their quality level. These firms can in fact remain stuck in the middle, if they do not have enough resources to turn quality into a source of sustainable competitive advantage.This paper is aimed at a better comprehension of both benefits and costs of a quality based strategy, with regard to a specific class of firms, Small Size Firms (SSFs), where a strategic use of quality is more difficult. The paper is articulated into two parts. Part one discusses the main obstacles facing the adoption of a quality based strategy by SSFs. A dynamic model for the adoption of this strategy over time, aimed at minimizing the risks for SSFs, is also presented.Part two describes the results of an empirical research, aimed at verifying the viability of quality based strategies in an industry composed only by SSFs, the shoe-machinery industry. The empirical research supports the viability of the model presented in the first part of the paper.     

Investigating the consumer–environment interaction through image modelling technologies

Abstract

This study uses an innovative research tool to evaluate the hypothesis of a consumer–environment interaction. A new computer graphics methodology keeps track of the time spent and the number of purchases made during shopping, together with several other behavioural measures. A laboratory experiment uncovered an interaction effect in dwell time and number of purchases between the type of shopping trip (fill-in trip vs. major trip) and the consumers' layout preference. Shoppers taking major trips were more prone to shop in a free-form layout, whereas those taking fill-in trips tended to prefer a grid layout. The article discusses implications for research and practice, identifying areas for future research.     

¿Hacia dónde evoluciona el tejido social contemporáneo? Nuevas tecnologías y viejas tendencias socioeconómicas

En este artículo se investiga si las sociedades asisten a una nueva revolución industrial, y cuál es la repercusión del cambio tecnológico en el tejido socioeconómico, principalmente con respecto al empleo, la distribución de la renta, las condiciones de trabajo y las relaciones laborales. Los autores sostienen que los procesos de innovación y la expansión de lo que denominan «automatización inteligente» tienden a exacerbar los actuales patrones de desigualdad de poder y de renta, que ya estaban presentes mucho antes la aparición de las tecnologías en cuestión. A tenor de esos procesos, proponen algunas recomendaciones para la formulación de políticas.     

Insurance and opportunities: A welfare analysis of labor market risk

Using a model with constant relative risk-aversion preferences, endogenous labor supply and partial insurance against idiosyncratic wage risk, this paper provides an analytical characterization of three welfare effects: (a) the welfare effect of a rise in wage dispersion, (b) the welfare gain from completing markets, and (c) the welfare effect from eliminating risk. The analysis reveals an important trade-off for these welfare calculations. On the one hand, higher wage uncertainty increases the cost associated with missing insurance markets. On the other hand, greater wage dispersion presents opportunities to raise aggregate productivity by concentrating market work among more productive workers. Welfare effects can be expressed in terms of the underlying parameters defining preferences and wage risk or, alternatively, in terms of changes in observable second moments of the joint distribution over individual wages, consumption and hours.
