Microeconomic modelling offers a powerful formal toolbox for analysing the complexities of real-world intergroup relations and conflicts. One important class of models scrutinizes individuals' valuations of different group memberships, attitudes towards members of different groups and preferences for resource distribution in group contexts. A second broad class uses game theoretical methods to study strategic interactions within and between groups of individuals in contest and in conflict. After a concise discussion of some essential peculiarities of microeconomic modelling, this review provides an overview of the pertinent literatures in economics, highlights instructive examples of central model types and points out several ways forward. This article is part of the theme issue 'Intergroup conflict across taxa'.

Environmental regulation and corporate exports: Quasi-experimental evidence from China's environmental protection tax law.
J Environ Manage
January 2025
School of Business Administration, Zhongnan University of Economics and Law, Wuhan, China. Electronic address:
How can we create a dual benefit scenario that improves both the ecological environment and export performance? This study aims to investigate whether the introduction of the Environmental Protection Tax Law (EPTL) has promoted the growth of corporate export. By treating the formal implementation of China's EPTL on January 1, 2018, as an exogenous economic event, this paper takes A-share listed companies in China from 2013 to 2022 as a sample and uses the Difference-in-Differences (DID) model to analyze the specific effects of the EPTL on corporate exports. The results indicate that the EPTL improves corporate exports significantly.

Article Synopsis
- Infectious diseases like schistosomiasis can harm labor productivity and income, creating a cycle of poverty and poor health for certain communities.
- Using fertilizer in agriculture can unintentionally promote aquatic vegetation that hosts disease-carrying snails, but removing this vegetation can decrease infection rates in children.
- A bioeconomic model shows that converting invasive aquatic plants into compost not only reduces disease but also enhances agricultural productivity and incomes, ultimately helping to break the poverty-disease cycle in rural communities.

Article Synopsis
- * Data analyzed from 173 villages between 2012 and 2019 shows that while there have been improvements in RLEI, there are still gaps in meeting farmers' expectations for a better quality of life.
- * The research suggests enhancing systems to attract skilled and ethical individuals for village leadership, along with modernized monitoring, to foster stronger rural development and community support.
Cost-Effectiveness of Intensive Blood Pressure Control in Youth With Chronic Kidney Disease.
Hypertension
February 2025
Department of Pediatrics (C.L.V., K.A.P., A.M.S., S.M.D.), Wake Forest University School of Medicine, Winston-Salem, NC.
Background: Intensive blood pressure (BP) control in youth with chronic kidney disease (CKD) slows progression, delaying the need for kidney replacement therapy (KRT). Most youth with CKD have hypertension and BP control is difficult to achieve outside of controlled experimental settings. Implementing effective BP control strategies in this population may be cost-saving despite requiring additional resources.

This study delves into the paradox of the financial resource curse, exploring how the abundance of natural resources in a country paradoxically constrains firms' accessibility to financing. Despite the potential economic boon natural resources represent, evidence suggests that they can lead to less diversified economies, making it challenging for firms outside the resource sector to access financing. Our research aims to dissect this phenomenon by analyzing microeconomic statistics on the financial accessibility of enterprises, juxtaposed with macroeconomic statistics across 170 countries, encompassing over 10,000 firms surveyed from 1990 to 2022.
