| Abstract: | We examine whether a company’s green and high–quality innovative strength is related to its environmental impact and what the implications are for its financial performance. By analyzing WIPO patent data and MSCI ESG data, we reveal a notable positive and statistically significant impact of possessing more green patents on a company’s carbon emissions score. Further, we find that the patent related increase in carbon emissions score is driven by the high–quality green patents. Our analysis validates the positive influence of green and high–quality innovation strength on both the E and ESG scores. Despite the positive impact on the environment, investors do not need to sacrifice returns. Investment strategies which invest in companies within the top decile of green patents or green patents ratio do not perform worse than the market. |

| Abstract: | City-level policies are increasingly recognized as key components of strategies to reduce transport greenhouse gas emissions. However, at a global scale, their total efficiencies, costs, and practical feasibility remain unclear. Here, we use a spatially-explicit monocentric urban economic model, systematically calibrated on 120 cities worldwide, to analyze the impact of four representative policies aiming at mitigating transportation GHG emissions, also accounting for their economic welfare impacts and health co-benefits. Applying these policies in all cities, we find that total transportation GHG emissions can be reduced by 31% in 15 years, compared with the baseline scenario. However, the consequences of the same policies vary widely between cities, with specific effects depending on the policy considered, income level, population growth rate, spatial organization, and existing public transport supply. Impacts on transport emissions span from high to almost zero, and consequences in terms of welfare can either be positive or negative. Applying welfareincreasing policy portfolios captures most of the emission reductions: overall, they reduce emissions by 22% in 15 years. Our results highlight that there is no one-size-fits-all policy. However, with context-specific strategies, large emission reductions can globally be achieved while improving welfare. |

| Abstract: | Feeding the expanding global population while reducing the environmental impact of farming and food supply is among the main challenges of the century. Cities, which host the large majority of the past decade demographic growth, are at the forefront. They are increasingly considering the relevance of developing policies to explicitly support less-intensive production and/or rebuild their foodshed so as to reduce their reliance on long-distance food transport. In this paper, we develop a spatial theoretical model to describe and discuss both economic and environmental implications of farming practices change and relocation strategies. We highlight that, compared to the market outcome, promoting less-intensive and local farming may improve the welfare provided that the marginal opportunity cost of urban land remains low enough. However, we also show that the conversion from conventional to alternative farming does not necessarily reduce GHG emissions and may, as a consequence, offset the positive effect on welfare. We finally conduct numerical simulations so as to illustrate the ambiguous impacts of food relocation. |
