    How does digital finance impact birth rates: Evidence from China
    (Elsevier B V on behalf of the Economic Society of Australia (Queensland) Inc, 2025-06) Chen J; Chi J; Smith D; Yuen M
    Digital finance (DF), the integration of tradition financial services and new information technology, has been shown to have various impacts in social behaviour. However, how DF affects people's fertility behaviour is still under investigation and worth exploring from the point of view of long-term economic growth. By employing a DF index, publicly available city-level birth rates in 287 Chinese cities, we find DF has a negative influence on birth rates. This finding is supported by endogeneity and several robustness tests. Mechanism tests show DF increases investment opportunities and therefore reduces the need of having children for support in old age. DF increases consumption and possibly individualism and also increases women's economic independence and their opportunity cost of having children, leading to lower birth rates. Given the development of DF is an inevitable trend, we further find that out of the three components of DF index measures, the coverage of DF significantly decreases birth rates, while the higher level of DF development, depth and digitalization, have much less negative impact on birth rates. Finally, this negative impact can be moderated when governments make policy efforts to increase educational and medical resources and provide protection of religion. This paper provides a novel perspective on the influence of DF on social behaviour through DF's direct impact on investments, consumption and income.

    Temminck pangolins relax the precision of body temperature regulation when resources are scarce in a semi-arid environment

    Climate change is impacting mammals both directly (for example, through increased heat) and indirectly (for example, through altered food resources). Understanding the physiological and behavioural responses of mammals in already hot and dry environments to fluctuations in the climate and food availability allows for a better understanding of how they will cope with a rapidly changing climate. We measured the body temperature of seven Temminck's pangolins (Smutsia temminckii) in the semi-arid Kalahari for periods of between 4 months and 2 years. Pangolins regulated body temperature within a narrow range (34-36°C) over the 24-h cycle when food (and hence water, obtained from their prey) was abundant. When food resources were scarce, body temperature was regulated less precisely, 24-h minimum body temperatures were lower and the pangolins became more diurnally active, particularly during winter when prey was least available. The shift toward diurnal activity exposed pangolins to higher environmental heat loads, resulting in higher 24-h maximum body temperatures. Biologging of body temperature to detect heterothermy, or estimating food abundance (using pitfall trapping to monitor ant and termite availability), therefore provide tools to assess the welfare of this elusive but threatened mammal. Although the physiological and behavioural responses of pangolins buffered them against food scarcity during our study, whether this flexibility will be sufficient to allow them to cope with further reductions in food availability likely with climate change is unknown.
