Innovation and Development: The Evidence From Innovation Surveys

In this article we investigate the existing evidence on innovation produced by innovation surveys in developing and emerging countries in Europe, Asia, Africa, and Latin America. We review the relevant literature, discuss methodological issues, and analyze the results for the countries with the most comparable surveys, considering the well-established findings of innovation surveys for Europe as a benchmark. From the evidence we considered, regional patterns are identified and some stylized facts on innovation and development are proposed, pointing out the specificity of innovation processes in economies engaged in industrialization and catching up.     

Managing Organizational Culture for Effective Internal Control. From Practice to Theory

Previous studies (see, for example, Carslaw, 1988; Thomas, 1989; Niskanen and Keloharju, 2000; Kinnunen and Koskela, 2002; Van Caneghem, 2002) clearly suggest that public companies' managers tend to round up the first digit of reported earnings (i.e. for companies reporting profits). Based on a sample of listed UK companies and employing earnings rounding-up behaviour (henceforth ERUB) as an indication of earnings management, I attempt to determine the impact of differences in audit quality on earnings management. When I rely on the very popular brand-name proxy (i.e. BigFive versus non-BigFive auditors) to capture differences in audit quality, findings are inconsistent with BigFive auditors constraining earnings management practices (i.e. findings suggest ERUB for both BigFive and non-BigFive clients). Employing an alternative proxy (i.e. based on auditors' industry expertise), findings are only weakly consistent with specialist BigFive auditors constraining earnings management (i.e. ERUB) practices.     

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.     

Do Agglomeration and Technology Affect Vertical Integration? Evidence from Italian Business Groups

The aim of this paper is to analyse the role of technology and spatial agglomeration in decisions about vertical integration. It starts from the hypothesis that the business group, defined as a set of firms under common ownership and control, is the appropriate unit to delimit the firm’s boundary. We use information drawn from input–output tables to detect the presence of positive inter‐industry exchanges and whether or not activities in a group are vertically related. Accounting for endogeneity problems, we estimate Probit and Linear Probability models to investigate the role of technology and spatial agglomeration on vertical integration decisions empirically. Consistent with property rights theory, our results show that the technology intensity of acquirers matters for backward integration choices and, moreover, that agglomeration plays a role in vertical integration only when it operates jointly with technology.     

Competition and coordination in experimental minority games

This work presents experimental results on a coordination game in which agents must repeatedly choose between two sides, and a positive fixed payoff is assigned only to agents who pick the minoritarian side. We conduct laboratory experiments in which stationary groups of five players play the game for 100 periods, and manipulate two treatment variables: the amount of information about other players’ past choices and the salience of information regarding the game history (i.e., the length of the string of past outcomes that players can see on the screen while choosing). Our main findings can be summarized as follows: aggregate efficiency in the game is in most cases significantly higher than the level corresponding to the symmetric mixed strategy Nash equilibrium. In addition, providing players with information about individual choices in the group does not improve aggregate efficiency with respect to when such information is absent. Displaying information about more rounds than just the previous one, on the other hand, seems to have a positive effect on aggregate efficiency. At the individual level, we find a stronger statistical relation between players’ current choices and their own past choices than between players’ choices and previous aggregate outcomes. In addition, the depth of the relation between present and past choices seems to be affected by the prompt availability of information about the game history. Finally, we detect evidence of a mutual co-adaptation between players’ choices over time that is partly responsible for the high level of efficiency observed.      

Inventory theory and the Beer Game

In this paper, data from a Beer Game simulation have been used to investigate whether education on the inventory theory makes a difference, in terms of inventory planning performance. The data from the present experiment show that education on models that are difficult to apply to the Beer Game do in fact make a difference, since education increases a planner's ability to keep orders relatively constant, and to match supply with demand. The analyses show that the inventory theory matters, even when it cannot be used directly.     

Off-the-job training and the shifting role of part-time and temporary employment across institutional models. Comparing Italian and British firms

This article investigates intensity and composition of off-the-job training investments of Italian and British firms in relation to their workforce heterogeneity with respect to the presence of non-standard workers. The main purpose is to assess the relationship between off-the-job training volumes and composition and the recourse to the main types of non-standard employment, that is temporary and part-time contracts, at firm level. Empirical evidence drawn from national surveys of the two countries shows more similarities than expected in terms of the correlation between non-standard employment and training volumes whilst substantial differences arise when disaggregating training interventions according to the types of skills to be developed. Both institutional settings and the different roles of part-time and temporary employment in the labour markets of the two countries contribute to the interpretation of the results.
