概括

政府可以利用经济增长和适度减少不平等来打击贫困. 印度可以在2030年之前通过适度的变化实现这一目标,而卢旺达需要大幅增长和减少不平等.

科学领域:

经济学经济学经济学
发展研究发展研究研究
社会政策社会政策社会政策

背景情况:

经济增长,收入不平等和减少贫困之间的联系是复杂的,并未完全理解.
现有的研究往往难以量化这些因素之间的精确相互作用.
政府在制定消除贫困的政策时面临着挑战,而不会加剧不平等.

研究的目的:

建立经济增长,收入不平等 (吉尼指数) 和减贫目标之间的可量化的关系.
开发和验证重新分配策略的通用化模型.
评估可行的增长再分配情景,以实现到2030年在印度和卢旺达实现可持续发展目标1 (消除极端贫困).

主要方法:

导出一个关闭形式的数学关系,将贫困门,吉尼指数变化和必需的国民收入增长联系起来.
开发一个通用的再分配模型.
与不平等的历史数据对模型的验证.
应用该模型模拟印度和卢旺达的消除贫困战略.

主要成果:

我们得出了一个公式,它独立于特定的收入分配形状.
该模型表明,印度可以在2030年之前消除极端贫困,以适度减少不平等,而单独的增长是不够的.
到2030年实现卢旺达的贫困目标将需要特别高的经济增长率和减少不平等.

结论:

经济增长本身并不总是足以消除贫困;再分配起着至关重要的作用.
针对不同国家环境而定制的增长和再分配战略是必不可少的.
该研究为决策者设计有效的减贫计划提供了定量框架.

Population Growth

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Sustainable Development

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Limits to Natural Selection

Limits to Natural Selection

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Nature and Nurture

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Egoism and Altruism

Egoism and Altruism

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?

Trophic Efficiency

Trophic Efficiency

Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.
