This study develops an integrated agent-based model (ABM) to simulate consumer adoption of sustainable food products, incorporating behavioural determinants identified through a structural equation model (SEM) that captures key variables influencing adoption decisions: environmental awareness, knowledge, price sensitivity, and perceived social norms. The ABM represents a heterogeneous artificial population in which agents make probabilistic consumption choices based on their attribute profiles and are subject to dynamic social influence via spatially proximate interactions, while policy interventions are operationalised within the model through information diffusion (awareness campaigns), norm amplification (peer influence enhancement), and economic incentives (price subsidies). An experimental design is employed to assess both individual and combined intervention effects on adoption dynamics, with results indicating that all three interventions yield statistically significant increases in sustainable product adoption rates. Norm reinforcement emerges as the most impactful standalone intervention, while combined strategies, particularly those integrating normative and informational components, exhibit nonlinear synergistic effects. The model also captures the diffusion of awareness across the agent network, highlighting the role of social dynamics in accelerating behavioural transitions. This research contributes to sustainability science by integrating behavioural modelling and simulation to assess the effectiveness of policy interventions and offers practical insights for the design of coordinated strategies that address both individual-level motivations and social mechanisms, supporting more effective efforts to foster sustainable food consumption.</div></div>","PeriodicalId":48015,"journal":{"name":"Journal of Policy Modeling","volume":"48 3","pages":"Article 107042"},"PeriodicalIF":3.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147994707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the efficacy of national fiscal policies within the EU in mitigating these twin pressures. Employing panel structural vector autoregression (PSVAR) models, we analyze the dynamic interplay between diverse fiscal policies and their inflationary repercussions across 20 EU countries from September 2021 to January 2023. The findings reveal a nuanced capability of fiscal interventions to temper energy-induced inflation, albeit with a limited overall impact on general inflation rates and energy prices. Price-suppressing measures exhibit the most significant and stable dampening effects while income-supporting policies yield the most erratic and unpredictable outcomes. The insufficient positive spillover effects of fiscal policies across EU member states underscore a fragmented fiscal policy framework, necessitating more coordinated effort and synergy. This study enriches the literature by empirically demonstrating the complex effects of fiscal policies on inflation and energy prices during crises. It underscores the urgency for an integrated and coherent fiscal strategy within the EU, advocating for institutional enhancements and cross-border policy harmonization. The practical implications of fostering a unified fiscal response are profound, offering a blueprint for mitigating current and future economic upheavals, thereby ensuring the EU’s long-term stability and prosperity.</div></div>","PeriodicalId":48015,"journal":{"name":"Journal of Policy Modeling","volume":"48 3","pages":"Article 107039"},"PeriodicalIF":3.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147994746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We build on Gertler’s (1999) model by introducing the pandemic as a negative shock to survival probabilities. Social distancing and lockdowns reduce mortality among older cohorts but simultaneously depress labor productivity, capturing the key demographic asymmetry of the pandemic. Within this framework, we construct age-specific welfare indices for “young” and “old” agents, as well as a relative welfare metric to evaluate intergenerational trade-offs. Our quantitative analysis yields four main results: (1) in the absence of containment measures, welfare losses are concentrated among older agents through a demographic channel; (2) lockdowns substantially shift the burden of welfare losses toward younger cohorts, reflecting the trade-off between mortality reduction and output contraction; (3) debt-financed fiscal expansions exert only a modest effect on relative welfare compared with the dominant impact of social distancing; (4) the intergenerational distribution of welfare depends critically on debt repayment strategies: front-loaded schemes disproportionately penalize younger generations, whereas postponed repayment schedules favor older cohorts, raising equity and policy-design considerations for future large-scale crises.</div></div>","PeriodicalId":48015,"journal":{"name":"Journal of Policy Modeling","volume":"48 3","pages":"Article 107043"},"PeriodicalIF":3.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147994754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have shown that proposed solutions to reduce inequality among social groups, such as single or multiple AA policies, have positive first-order effects on outcomes such as enhanced enrollment, fewer dropouts, higher attendance, and lower performance differences. However, the second-order effect of AA policies on </span>labor market<span><span> outcomes remains understudied, with mixed findings. Therefore, this study employs a quasi-natural experiment with data from 21,270 graduate students and a difference-in-differences strategy to estimate the impact of AA policies on educational and skill performance, thereby reducing inequality. We find that AAs significantly reduce educational inequalities, while significantly increasing the skills gap. However, the impact of AAs on these outcome variables was small. Furthermore, the skill difference was significantly higher than the educational gap. Hence, while AAs increase </span>access to education<span>, they may not necessarily enhance employment-related skills or competencies. Consequently, we advocate continuing AA policies to provide short-term relief to disadvantaged groups seeking access to educational institutions. However, individual skills and competencies are required for employment and cannot be addressed through AA policies. Given the larger skill difference even after an undergraduate degree, we propose that AA policies are institutionally required to overcome the skill gap. In other words, there could be greater emphasis on skill development, such as bridge programs, specialized courses, supplementary classes, and remedial courses, to improve employment outcomes for persons from historically marginalized groups.</span></span></div></div>","PeriodicalId":48015,"journal":{"name":"Journal of Policy Modeling","volume":"48 2","pages":"Pages 429-447"},"PeriodicalIF":3.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147552107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
