This paper aims to explore the effect of sustained high inflation on public procurement participation in the European Union, both in terms of the average number of bids submitted and in the proportion of bids by small- and medium-sized enterprises (SMEs) out of all submitted bids.

Regression modelling, using contract award notices in the Tender Electronics Daily database between 2018 and 2022, at quarterly intervals.

Each inflation point increase is associated with a decline in the average number of offers received per tender by 0.43%. A more marked reduction of 8.6% in the average number of offers and a decrease in 3.4 percentage points in the SME participation rate are observed for firms operating in sectors that experienced very high levels of inflation (>20% year-on-year rate of change), compared with a situation of low inflation (0–5%).

Claims about difficulties in delivering public contracts for the set price should be taken with a grain of salt, unless businesses operate in sectors experiencing very high inflation levels. Measures to foster competition could also reduce price pressures.

To the best of the authors’ knowledge, this is the first study to quantitatively assess the association between high inflation and public procurement participation. Two methodological novelties are introduced: the operationalisation of sectoral-level inflation down to two-digit NACE codes, based mainly on producer prices; and a matching between two-digit NACE codes for inflation and the common procurement vocabulary codes to classify calls to bid for public contracts by economic activity.

This opening chapter introduces key debates in relation to informality in policymaking, laying the theoretical and conceptual groundwork for the individual empirical chapters, beginning with a provocation for how informality can alternatively be understood. Through illustrating where gaps in understanding within current literature exist for how informality acquires meaning, and the physical and material relevance for how it manifests across contexts, this chapter introduces the three thematic clusters that thread through the book’s chapters: boundaries, knowledge mastery and networks. In doing so, it briefly positions each chapter in relation to these flexible and overlapping categories, drawing attention to how each chapter presents a different understanding of informality. Key to this chapter is our contention that while informality escapes definition, without binary or fixed conceptualisations of this concept we are better able to take in its fluidity and envisage how it is interwoven in everyday policy work and its human and non-human enactment. Underpinning this contention is a key contribution of this work, a proposition for a re-conceptualising of informality and formality as in|formality. Methodologically, this chapter argues that informality is better ‘shown’ than ‘told’ – and that this can be achieved through interpretive and socio-material approaches woven through disciplines that foreground narrative, ethnographic and creative approaches to research.

Productivity is often cited as a key barrier to the adoption of metal laser-based powder bed fusion (ML-PBF) technology for mass production. Newer generations of this technology work to overcome this by introducing more lasers or dramatically different processing techniques. Current generation ML-PBF machines are typically not capable of taking on additional hardware to maximise productivity due to inherent design limitations. Thus, any increases to be found in this generation of machines need to be implemented through design or adjusting how the machine currently processes the material. The purpose of this paper is to identify the most beneficial existing methodologies for the optimisation of productivity in existing ML-PBF equipment so that current users have a framework upon which they can improve their processes.

The review method used here is the preferred reporting items for systematic review and meta-analysis (PRISMA). This is complemented by using an artificial intelligence-assisted literature review tool known as Elicit. Scopus, WEEE, Web of Science and Semantic Scholar databases were searched for articles using specific keywords and Boolean operators.

The PRIMSA and Elicit processes resulted in 51 papers that met the criteria. Of these, 24 indicated that by using a design of experiment approach, processing parameters could be created that would increase productivity. The other themes identified include scan strategy (11), surface alteration (11), changing of layer heights (17), artificial neural networks (3) and altering of the material (5). Due to the nature of the studies, quantifying the effect of these themes on productivity was not always possible. However, studies citing altering layer heights and processing parameters indicated the greatest quantifiable increase in productivity with values between 10% and 252% cited. The literature, though not always explicit, depicts several avenues for the improvement of productivity for current-generation ML-PBF machines.

This systematic literature review provides trends and themes that aim to influence and support future research directions for maximising the productivity of the ML-PBF machines.

The objective of this article is to make an exploratory study about European public administrations (public administration, public agencies, public law entities, entities dependent on the public administration and public universities) in relation to workplace health promotion interventions. The sample was extracted from the ESENER-3 (Third European Survey of Enterprises on New and Emerging Risks) (EU-OSHA, 2019) and consists of 7,981 public entities from the EU-27 countries. Four WHPI have been studied: healthy nutrition interventions, sports activities after working hours, back exercises at work and prevention of addictions.

This is an exploratory study. The sample was extracted from the ESENER-3 (Third European Survey of Enterprises on New and Emerging Risks) (EU-OSHA, 2019) and consists of 7,981 public entities from the EU-27 Public Administration. In total, 45,420 establishments were interviewed.

Different patterns have been observed when implementing workplace health promotion interventions in the EU-27 public administration. The promotion of sports activities outside working hours is the one with the highest level of implementation in European public administration. On the other hand, the measure with the least implementation level is the promotion of healthy nutrition.

The limitations of the study are that the studied items are nominal and comprise more than two categories, so it has not been possible to develop a correlation analysis.

The EU-27 public administrations can see which workplace health promotion interventions need to be improved.

Differences that may exist in the adopted workplace health promotion interventions by European public administrations have not yet been addressed in depth by the literature.
