Attempts by the private sector to intervene in government environmental policy might affect environmental policy, the dynamic behavior of the economy, and its long-term sustainability. To elucidate these effects, this paper presents a simple overlapping generations model with environmental externalities and politically motivated governments. If abatement technology is high and the government enforces optimal environmental policies, then the per-capita growth rate becomes positive and environmental quality improves over time. This study considers the case in which interest groups make a political donation or offer a bribe to prevent a government from introducing environmental policies. If the marginal benefit of such donations is sufficiently high, then the government accepts political contributions and delays the introduction of environmental policies. In such cases, even in economies with the capacity to achieve sustainable growth, the dynamic economic behavior might be destabilized, cycles might occur, or long-term economic growth rates might become negative. Numerous previous studies have demonstrated that corruption reduces the growth rate and degrades environmental quality. However, the dynamic behavior of the economy has not been adequately explored. This paper, therefore, examines not only the steady-state properties of the economy but also its dynamic behavior. A key contribution of this study is to show that political contributions and bribery may not only lower the long-run growth rate and worsen environmental quality, but also destabilize the dynamic trajectories of output and the environment — an aspect that has been largely overlooked in the existing literature. This conclusion suggests the necessity of establishing institutions and laws capable of preventing political corruption for an economy not to fall into a trap and achieve sustainable development. Moreover, investment and innovation must occur to increase productivity. The study is relevant to Goal 8 of the UN Sustainable Development Goals (Target 8.4), which provides a theoretical basis for identifying the conditions necessary to achieve economic growth without environmental degradation.</div></div>","PeriodicalId":100674,"journal":{"name":"Innovation and Green Development","volume":"4 4","pages":"Article 100281"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144907249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach effectively addresses heterogeneity, structural changes, and cross-sectional dependency in panel data analysis, ensuring robust and reliable insights. The findings reveal significant variation in the impact of renewable energy consumption on economic growth across the G7 countries. In Japan, the effect is positive and statistically significant, supporting the green growth hypothesis. This outcome is attributed to Japan's strong tradition of technological innovation, which enables effective integration and adaptation of renewable energy technologies. Conversely, Italy exhibits a negative and significant impact, highlighting challenges in aligning renewable energy with its economic framework. For Canada, France, Germany, the UK, and the US, the effect is not statistically significant, suggesting that renewable energy consumption has not yet become a major driver of economic growth in these nations. The study underscores that the transition to green growth in G7 countries faces several obstacles, including outdated infrastructure, volatile energy prices, competition from fossil fuels, and insufficient investment in renewable technologies. These factors can impede innovation and limit the economic contributions of renewable energy.
