This study advances the economic development scholarship through three key contributions. First, it examines the impact of distributional energy justice (hereafter referred to as energy justice) on inclusive human development (IHDI) in Africa. Second, we investigate how climate readiness moderates the effect of energy justice on IHDI. Third, we explore whether the joint effect of energy justice and climate readiness differs across low- and high-income African countries. We make these contributions using macro data for 36 African countries from 2010 to 2020. The results reveal that energy justice promotes IHDI. The contingency analysis also demonstrates that climate readiness amplifies the po..

Countries with a low share of global emissions may perceive their cooperation in decarbonization as less critical yet economically burdensome. While non-cooperating countries may benefit from reduced global emissions at lower direct costs, they can also face significant environmental consequences. This paper investigates an asymmetric scenario in which most countries engage in decarbonization efforts while a single country adopts a free-riding strategy, focusing on Mexico as a case study. Our study provides insights into investment needs compared to environmental implications for a country with a free-riding strategy. The investment needs under free-riding tend to be higher than a baseline s..

Using large-scale high-granularity data from a food delivery platform and granular pollution and weather information, we study how PM2.5 fluctuations affect riders’ absenteeism, productivity, and accidents. Exploiting exogenous pollution variation from inverse boundary layer height, we find that higher pollution increases absenteeism for all workers and raises delivery times and accident rates only among (e-)bike riders, who must exert physical effort while working. Affected workers compensate productivity losses by working longer hours. Monetary incentives mitigate the effects on absenteeism but do not offset the decline in productivity and appear to exacerbate accident risk.

In Open Veins of Latin America (1971), Eduardo Galeano argued that colonial interventions in Latin America organised the regional economy around raw material exports and drained the continent of valuable resources and labour, producing conditions of underdevelopment. Scholars have argued that this dynamic continues today, where the suppression of prices and input costs in peripheral regions enables the global North to appropriate resources and value through ‘unequal exchange’. Building on this analysis and grounded in the Marxist tradition of dependency theory, this study empirically assesses Latin America's position with respect to unequal exchange of natural resources and labour embodi..

The primary objective of this paper is to explore the determinants of the level of, and trends over time in, Japan's household saving rate, with emphasis on the impact of the age structure of the population, and to make projections about future trends therein. The paper finds that Japan's household saving rate has not always been high either absolutely or relative to other countries, contrary to popular belief, and that, if we confine ourselves to the postwar period, it was only during the 25-year period from 1961 to 1986 that it exceeded 15%. Past and future trends in Japan's household saving rate can largely be explained by changes in the age structure of her population, but declines in th..

Policies promoting green transportation, particularly cycling, are gaining importance in the context of climate change. In order to elucidate the mechanisms behind cycling adoption, this paper proposes a novel compartmental model, which incorporates the time-varying effects of both social influence and contextual factors. We provide a mathematical analysis of the model, showing global convergence to an equilibrium. We also developed a case study of Grenoble, France, which showcases the model's ability to characterize cycling adoption dynamics, highlighting its potential to support sustainable transportation policy design.

The EU has set an objective of reaching 10% of landscape features on its agricultural land by 2030 as part of its latest Biodiversity Strategy. This share is often considered the minimum amount of semi-natural habitats required to halt biodiversity declines and ensure the provision of ecosystem services. This policy objective has faced considerable political opposition due to potentially high budgetary and opportunity costs. We explore farmers' preferences towards hypothetical incentive schemes that ensure the provision of 10% of semi-natural habitats at the landscape level. We use the results of a discrete choice experiment to estimate the total budgetary costs of different schemes and pote..

This paper studies how the distribution of preference intensity affects product survival. Consumers may have the same average valuation of a product attribute, yet differ sharply in how concentrated that valuation is across the population. I show that this distinction matters for market selection. In a differentiated-product economy with fixed operating costs, a product survives only if it attracts enough revenue to cover its fixed cost. When the revenue contribution of consumers is convex in preference intensity, concentrating a fixed aggregate valuation among fewer high-intensity consumers raises the revenue of high-attribute products. Thus, small groups of strongly attached consumers can ..

This study analyzes vertical channel integration versus decentralization with products of different environmental quality under supply chain competition. We first examine the strategic impact of different channel structures on environmental quality, firms' profits, and welfare. Specifically, we analyze and compare different channel structures: no integration (decentralization), ordinary product channel integration, green product channel integration, and full channel integration. It is found that more channel integration will cause more intense competition in terms of environmental quality decisions between the manufacturers and thus lower profits. Therefore, the manufacturers always prefer d..

This study investigates the temporal and contextual stability of social risk preferences across health and wealth, focusing on both gains and losses. Using a large representative Dutch panel, we replicated the experimental design of Attema et al. (2023) which elicited social risk preferences through allocation decisions involving two anonymous recipients under risk. The design allows us to distinguish three dimensions of preferences: risk preferences, inequality aversion, and social risk preferences arising from trade-offs between risk and inequality, corresponding to utilitarian, ex-ante, and ex-post perspectives on social welfare. At the aggregate level, the main patterns documented in the..

Across advanced economies, states are reasserting a more directive role in shaping markets. One prominent expression of this shift is the resurgence of industrial policy as a form of interventionist economic governance. This introduction develops a tripartite framework to analyze contemporary industrial policy in terms of goals, instruments, and authority structures—asking for what ends states intervene, through what means, and by and for whom. Applying this lens to Europe and the European Union (EU), the special issue shows how a polity long seen as the archetype of the regulatory state is increasingly departing from this model through a renewed embrace of industrial policy. We identify f..

Utility companies recover their capital costs through regulator-approved rates of return. Using a comprehensive database of utility rate cases, we find a significant premium for regulated returns on equity relative to several capital cost benchmarks. We show that firms decide strategically when to initiate new rate cases, such that regulated returns respond more quickly to increases in underlying capital cost benchmarks than to decreases. Higher regulated returns incentivize utilities to own more capital: a one percentage point rise in return on equity corresponds to an increase in capital assets of 2%–4%. Overall we find excess costs to U.S. consumers averaging $7 billion per year.

Background Countries around the world worry about the financial sustainability of their health systems as populations age; however, few have considered the consequences of future gaps in health financing on the risk of financial hardship due to out-of-pocket payments. If countries are unable to raise sufficient revenues to meet health needs, people will pay more out-of-pocket to use health services and risk experiencing catastrophic or impoverishing health spending. Objective We aim to simulate the effect of health financing gaps due to changes in the population age-mix on the risk of financial hardship from out-of-pocket payments and to identify relevant policy mechanisms. Methods Using the..

This research addresses inequalities in access to essential resources and services (food, health, energy, education). It shows that territorial and social access inequalities stem as much from structural determinants—such as supply chain organization, infrastructures, rules, and power relations—as from individual decisions. Focus of the Article The article repositions social marketing within a justice-oriented systemic perspective. Rather than focusing solely on information or awareness, the objective is to transform the access conditions that shape practices. The approach is explicitly audience-oriented, emphasizing lived experience, frictions, and renunciation; it calls for segmenting ..

Logistics and supply chain resilience have become a critical priority in an era of increasing global uncertainty. The Physical Internet (PI) offers a transformative vision for logistics: an open, shared, and interconnected network that inherently promises greater resilience and sustainability. This paper investigates how PI principles can be proactively integrated into multimodal logistics networks to enhance their resilience and environmental performance. We first propose a pragmatic decision-making framework to guide managers through a step-by-step process for logistics network design and enhancement. Building on this framework, we develop two PI-based resilient network redesign strategies..

This paper investigates the long-term impact of the 1920s forced displacement of Asia Minor refugees on contemporary health behaviors in Greece. Using regionally representative data from the 2019 Greek Health Survey and historical refugee settlement patterns, we find that individuals living in areas with higher historical shares of refugees are significantly more likely to engage in preventive health care, consult medical professionals, participate in physical activity, and maintain healthy dietary habits. These effects persist after controlling for socioeconomic, demographic, and geographic factors, and are robust to various specifications, including the exclusion of Attica, the main intern..

Water-saving technologies contribute to mitigating the environmental impact of agriculture and raising farmers' incomes by reducing production input and enhancing crop quality. The promotion of water-saving technologies commonly requires government support and intervention. This study investigates two subsidy schemes: the dynamic scheme and commitment scheme, in terms of social welfare, supplier profits and farmer surplus. We develop an analytical model to analyze the interactions within an agricultural supply chain consisting of a government, a water-saving equipment supplier and heterogeneous farmers across two periods, taking social influence and technological advancement into considerati..
