The Unassuming Economist

From a paper by Richard Schmitz, Franziska Flachsbarth, Leonie Sara Plaga, Martin Braun, and Philipp Härtel:

“Recent events, including the pandemic, geopolitical conflicts, supply chain disruptions, and climate
change impacts, have exposed the critical need to ensure energy security and resilience in energy
systems. We review existing definitions and interrelations between energy security and resilience,
conceptualising these terms in the context of energy system transformations. We introduce a classification of disturbances into shock events and slow burn processes to highlight key challenges to energy system resilience. Examples illustrate their distinct impacts on technical, economic, and environmental system performance over time. We compile relevant recourse options across resilience capacity levels and system planning horizons to address these challenges, emphasising actionable strategies for an increasingly integrated energy system. Finally, we propose policy recommendations to integrate shock events and slow burn processes into future energy system planning, enabling forward-looking decision-making and system design to analyse and mitigate potential disruptions.”

From a paper by Loek Groot and Chintani Sooriyamudali:

“This paper estimates the global Kuznets curve (2005-2020) by plotting global mean income against global inequality, while exploring COVID-19’s impact on inequality. Using PPP adjusted GDP per capita and Gini index data from 122 countries (94% global GDP, 88% population), global income is simulated assuming lognormality. The paper finds that, at the pandemic outbreak, the world was on the downward part of the Kuznets curve. Compared to within-country inequality, between country inequality contributes significantly to global inequality. While the pandemic may temporarily decelerate the decline of global inequality, the long-term impact will be determined by the level of international cooperation in the global response to the pandemic.”

From a paper by Jingye Liu, Fengqi Guo, Ying Shi, Rijia Ding, and Zhen Chen:

“The recurrence of international geopolitical events has intensified tensions in global energy supply chains. As a major crude oil consumer, China urgently needs to identify vulnerabilities within its crude oil supply chain (COSC) and implement targeted measures to safeguard national energy security. In this study, a risk evaluation index system was constructed based on the entire life cycle in COSC. Then, the phased and overall prominent risks in the China’s COSC from 2012 to 2022 were identified through a two-phase DEA-like model. Furthermore, the evolution of the comprehensive security level of COSC was assessed throughout the study period. Specifically, the phased risks of China’s COSC mainly focused on strategic petroleum reserves (SPR) in the midstream application stage and refined oil trade in the downstream consumption stage. Additionally, China’s COSC primarily confronted overall risks involving domestic crude oil supply potential, geopolitical imports, maritime transportation, and domestic oil consumption. Although the security level of China’s COSC showed an upward trend from 2012 to 2022, the security of the upstream still lagged behind that of the midstream and downstream. Hence, policy recommendations to enhance China’s COSC security include advancing the exploration and development of unconventional oil, strengthening international energy cooperation and the autonomy of maritime transportation, expanding the SPR, increasing the proportion of renewable energy, and establishing a risk early warning platform.”

From a paper by Daniel Halvarsson, and Martin Korpi:

“This study investigates the relationship between the urban wage premium and employer concentration using Swedish full population employer-employee data. Departing from an AKM modeling framework to distinguish worker from firm specific heterogeneity – a measure of rent-sharing – we then measure the urban wage premium using differences in the estimated firm fixed effects at the level of local industries, nested within local labor markets. Our results suggest that labor market employer concentration, as calculated using the Hirschman-Herfindahl index and a leave-one-out instrumental variable design, can account for a significant share of the estimated urban wage premium (UWP). Addressing city-level wage income inequality by applying our model to different segments of the local labor market income distribution, we find that while the UWP pertains to all income segments, it is largest for top-income levels (above the 90th percentile), and within this segment employer concentration also has the largest explanatory power. Thus, while being an important explanatory factor for all percentiles of the local income distribution, a relatively lower employer concentration within larger cities, and vice versa, higher concentration within smaller cities, primarily help explain the variance of top wages within these cities/labor markets.”
