- We introduce a static cost model that simulates the cost of decarbonizing the heavy-duty road transport sector. This time-variant model aims to refine existing estimations of investment needs under different scenarios. The paper advances sustainability transition’s cost analysis in three ways: 1) providing a novel methodological tool, 2) including the financing cost in the analysis, and 2) testing the cost variance under different charging strategies for battery-electric vehicles and financing interest rates. A plausible scenario is applied to test the model. The paper discusses charging opportunities reliant on charging place, time, power effect, and electricity selfconsumption within the charging strategies. Our results highlight the vital contribution of charging strategies to fuel and capital expenses for the system. Moreover, system cost analysis reacts to the change in financing policies, stressing the criticality of sustainable financing in the sustainability transition’s advancement

Cost and financing of the sustainability transition of the Swedish road freight transport sector
- 2023

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research. It explores the financing dynamics of the transition for this sector at both the strategic and tactical levels, and it investigates circular economy (CE) transition barriers specific to BEV batteries. Six studies are developed, involving multiple sources of data and methodological approaches: systematic literature review, numerical modeling and scenario testing, data-driven agent-based simulation, network analysis, and interviews. The findings reveal that charging strategies have a substantial impact on BEV costs, especially in scenarios with higher adoption rates. This is attributed to electricity price fluctuations based on charging location, timing, power, and source. High hydrogen prices in scenarios with a high number of FCVs lead to increased fuel costs. Interestingly, the impact on loading capacity for larger powertrains in both BEVs and FCVs is relatively minor compared to other costs. The capacity of batteries depends on charging ranges and temperatures, but their impact would not significantly affect cost savings through increased BEV salvage values where a CE initiative is in place. A set of regulatory, market, structural, technological, actor-related, and task-related barriers and their complex interactions are identified that hinder BEV transition from a linear to a circular system. The availability of financing is crucial for facilitating the transition and is highly contingent on the financial strength and creditworthiness of companies, particularly given the prevalence in the sector of micro and SMEs, which often encounter challenges in accessing financing.

The effects of bargaining power on trade credit in a supply network

Tidskriftsartikel (refereegranskat)abstract
- We develop a multi-tier supply network model, rooted in social network theory, to evaluate the effect of bargaining power on trade credit and to track the effect of buyers' trade credit on suppliers' trade credit. We apply social network analysis to measure companies' bargaining power in the supply network of Hennes & Mauritz AB (H&M, the Swedish clothing retailer). The results show that the buyer's bargaining power significantly affects the choice of trade credit, and that the supplier's “upstreamness” is significantly associated with its trade credit. We find limited evidence to support the notion of a financial bullwhip effect, a result that merits further research, since this study is limited to the network of one company up to its fourth tier of suppliers in one financial year. Our results can be applied by companies seeking to control their cash flow and, therefore, the financial pressure within their supply network. This study contributes to the literature by bringing social network measures into the buyer–supplier financial flow, as well as offering one of the first empirical examinations of the propagation of financial pressure in a multi-tier supply network.
