Optimizing carbon tax for decentralized electricity markets using an agent-based model

Averting the effects of anthropogenic climate change requires a transition from fossil fuels to low-carbon technology. A way to achieve this is to decarbonize the electricity grid. However, further efforts must be made in other fields such as transport and heating for full decarbonization. This would reduce carbon emissions due to electricity generation, and also help to decarbonize other sources such as automotive and heating by enabling a low-carbon alternative. Carbon taxes have been shown to be an efficient way to aid in this transition. In this paper, we demonstrate how to to find optimal carbon tax policies through a genetic algorithm approach, using the electricity market agent-based model ElecSim. To achieve this, we use the NSGA-II genetic algorithm to minimize average electricity price and relative carbon intensity of the electricity mix. We demonstrate that it is possible to find a range of carbon taxes to suit differing objectives. Our results show that we are able to minimize electricity cost to below \textsterling10/MWh as well as carbon intensity to zero in every case. In terms of the optimal carbon tax strategy, we found that an increasing strategy between 2020 and 2035 was preferable. Each of the Pareto-front optimal tax strategies are at least above \textsterling81/tCO2 for every year. The mean carbon tax strategy was \textsterling240/tCO2.Comment: Accepted at The Eleventh ACM International Conference on Future Energy Systems (e-Energy'20) AMLIES Worksho

Industrial strategy and the UK regions: Sectorally narrow and spatially blind

The UK government's new Industrial Strategy could have a significant impact on the country's regions and localities. However, this has received little attention to date. The analysis presented here examines the existing location of the sectors targeted by the first phase of the Industrial Strategy Challenge Fund and the location of the R&D laboratories likely to be first in line for funding. In focusing on an extremely narrow range of sectors, the Fund is likely to have limited impact on the UK's persistent regional inequalities. The activities eligible for support account for relatively little of manufacturing or the rest of the economy and the basis of this targeting and its potential distributional consequences are spatially blind. As such, it runs the risk of widening regional divides in prosperity

Paying for free delivery: dependent self-employment as a measure of precarity in parcel delivery

This article explores supply chain pressures in parcel delivery and how the drive to contain costs to ‘preserve value in motion’, including the costs of failed delivery, underpins contractual differentiation. It focuses on owner-drivers and home couriers paid by delivery. It considers precarity through the lens of the labour process, while locating it within the supply chain, political economy and ‘instituted economic process’ that define it. Focus on the labour process shows how ‘self-employment’ is used to remove so-called ‘unproductive’ time from the remit of paid labour. Using Smith’s concept of double indeterminacy the article captures the dynamic relationship between those on standard and non-standard contracts and interdependency of effort power and mobility power. It exposes the apparent mobility and autonomy of dependent selfemployed drivers while suggesting that their presence, alongside the increased use of technology, reconfigures the work-effort bargain across contractual status

Modelling UK sub-sector industrial energy demand

The importance of considering homogenous economic agents when estimating energy demand functions is recognized in the literature, but so far data availability problems have explained the prevalence of empirical analyses only at an aggregate level. Motivated by the goal of developing the new industrial module to be adopted by the UK government Department of Business, Energy and Industrial Strategy (BEIS) for their econometric Energy Demand Model, we propose the first cointegration analysis that provides evidence on energy demand elasticities with respect to economic activity and energy price at a disaggregated industrial level. While the average of our estimates are comparable to those of the existing literature on the industrial sector as a whole, we find that there is considerable heterogeneity in relation to the long-run impact of economic activity and energy price on energy consumption, as well as to the speed with which firms re-adjust their equilibrium demand of energy in response to economic shocks. Finally, we learn that long-run disequilibria are tackled through altering the level of energy consumption rather than economic activity, a conclusion that has important implications for policy analysis

A practitioner concept of contemporary creativity

This article reviews conceptualisations from three academic areas: the sociology of art, the psychology of creativity, and research on the cultural and creative industries. These are compared with findings from a critical discursive study with UK practitioners. The meanings and associations these ‘maker artists’ attach to creativity are discussed as a ‘practitioner concept’. For the practitioners, the association of creativity with art carries a promise of transcendence and escape from ordinary life, but also a potential challenge to their own entitlement and claims to a creative status. The article shows, first, that the academic areas utilise different and conflicting conceptualisations and, second, that the practitioner concept is not consistent with any one of these. The article argues that the contemporary celebration of creativity is based on different meanings and unacknowledged conflicts. The article proposes that future social psychological research on creativity requires a more critical approach to the concept

A 'place based' approach to work and employment: the end of reciprocity, ordinary working families and 'giggers' in a place

The authors define ‘place basing’ as the study of work and employment in a particular place. They are interested in understanding the limitations of work opportunities therein and so focus on workers and jobs that are not subject to the threat of off-shoring or relocation elsewhere but which are low paid and insecure. The authors theorize three contributions to new knowledge that flow from a place-based study of work and employment by demonstrating how precarious flexible often zero hour work eschews reciprocity between employer and employees and workers. They focus their research on ordinary working families and the ‘permissive visibility’ of bad work. The research points to an idealized model of individual and family economic functioning that is able to cope with physical and mental challenges individually without burdening the state. As the findings on workers and households demonstrate, this ideal is far from the reality they experience

The implications of direct participation for organizational commitment, job satisfaction and affective psychological well-being: a longitudinal analysis

The paper examines the implications of direct participation for employees’ organizational commitment, job satisfaction and affective psychological well-being. It focuses on both task discretion and organisational participation. Applying fixed effect models to nationally representative longitudinal data, the study provides a more rigorous assessment of the conflicting claims for the effects of participation which have hitherto been based primarily on cross-sectional evidence. Further, it tests a range of mechanisms by which direct participation leads to improved employee outcomes. Contrary to the critical literature, it shows that even after controlling for unobserved individual heterogeneity, both forms of direct participation have positive effects for employees’ organizational commitment and well-being. The effects of task discretion are primarily direct, reflecting the intrinsic importance of personal control over the job task; in contrast, those of organizational participation derive to a greater extent from its indirect effect on the quality of working conditions
