Economics is a social science that studies the production, distribution, and consumption of goods and services.
Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study topics such as output/GDP and national income, unemployment, price indices and inflation, consumption, saving, investment, energy, international trade, and international finance.
In economics, stagflation or recession-inflation is a situation in which the inflation rate is high or increasing, the economic growth rate slows, and unemployment remains steadily high. It presents a dilemma for economic policy, since actions intended to lower inflation may exacerbate unemployment.
In economics, the fiscal multiplier is the ratio of change in national income arising from a change in government spending. More generally, the exogenous spending multiplier is the ratio of change in national income arising from any autonomous change in spending. When this multiplier exceeds one, the enhanced effect on national income may be called the multiplier effect. The mechanism that can give rise to a multiplier effect is that an initial incremental amount of spending can lead to increased income and hence increased consumption spending, increasing income further and hence further increasing consumption, etc., resulting in an overall increase in national income greater than the initial incremental amount of spending. In other words, an initial change in aggregate demand may cause a change in aggregate output that is a multiple of the initial change.
In economics, money illusion, or price illusion, is a cognitive bias where money is thought of in nominal, rather than real terms. In other words, the face value of money is mistaken for its purchasing power at a previous point in time. Viewing purchasing power as measured by the nominal value is false, as modern fiat currencies have no intrinsic value and their real value depends purely on the price level. The term was coined by Irving Fisher in Stabilizing the Dollar. It was popularized by John Maynard Keynes in the early twentieth century, and Irving Fisher wrote an important book on the subject, The Money Illusion, in 1928.
Sendhil Mullainathan is an American professor of Computation and Behavioral Science at the University of Chicago Booth School of Business and the author of Scarcity: Why Having Too Little Means So Much. He was hired with tenure by Harvard in 2004 after having spent six years at MIT.
In economics, a cycle of poverty or poverty trap is when poverty seems to be inherited causing subsequent generations to not be able to escape it. It is caused by self-reinforcing mechanisms that cause poverty, once it exists, to persist unless there is outside intervention. It can persist across generations, and when applied to developing countries, is also known as a development trap.
The Financial Access Initiative (FAI) is an American consortium, established in 2006, of researchers at New York University (NYU), Yale University, Harvard University and Innovations for Poverty Action (IPA) focused on finding answers to how financial sectors can better meet the needs of poor households.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity namely physical and economic water scarcity. Physical water scarcity is where there is not enough water to meet all demands, including that needed for ecosystems to function. Arid areas for example Central Asia, West Asia, and North Africa often experience physical water scarcity. Economic water scarcity on the other hand, is the result of lack of investment in infrastructure or technology to draw water from rivers, aquifers, or other water sources. It also results from weak human capacity to meet water demand. Much of Sub-Saharan Africa experiences economic water scarcity.
Jonathan Morduch is a professor of public policy and economics at the Robert F. Wagner Graduate School of Public Service at New York University. He is a development economist most well known for his significant academic contributions to assessing the impact of microfinance since the early years of the movement. He has written extensively on poverty and financial institutions in developing countries and on tensions between achieving social impacts and meeting financial goals in microfinance.
The aim of water security is to make the most of water's benefits for humans and ecosystems. The second aim is to limit the risks of destructive impacts of water to an acceptable level. These risks include for example too much water (flood), too little water or poor quality (polluted) water. People who live with a high level of water security always have access to "an acceptable quantity and quality of water for health, livelihoods and production". For example, access to water, sanitation and hygiene services is one part of water security. Some organizations use the term water security more narrowly for water supply aspects only.
The Center for Population Economics is a research center at the University of Chicago Booth School of Business. The work of the CPE is funded primarily by the U.S.'s National Institute on Aging of the National Institutes of Health.
Dean Karlan is an American development economist. He is Chief Economist of USAID and Professor of Economics and Finance at Northwestern University where, alongside Christopher Udry, he co-founded and co-directs the Global Poverty Research Lab at Kellogg School of Management. Karlan is the president and founder of Innovations for Poverty Action (IPA), a New Haven, Connecticut, based research outfit dedicated to creating and evaluating solutions to social and international development problems. He is also a Research Fellow and member of the Executive Committee of the board of directors at the Abdul Latif Jameel Poverty Action Lab (J-PAL) at the Massachusetts Institute of Technology. Along with economists Jonathan Morduch and Sendhil Mullainathan, Karlan served as director of the Financial Access Initiative (FAI), a consortium of researchers focused on substantially expanding access to quality financial services for low-income individuals.
Climate change and poverty are deeply intertwined because climate change disproportionally affects poor people in low-income communities and developing countries around the world. The impoverished have a higher chance of experiencing the ill-effects of climate change due to the increased exposure and vulnerability. Vulnerability represents the degree to which a system is susceptible to, or unable to cope with, adverse effects of climate change including climate variability and extremes.
Water scarcity in Africa is predicted to reach dangerously high levels by 2025 when it is estimated that about two-thirds of the world's population may suffer from fresh water shortage. The main causes of water scarcity in Africa are physical and economic scarcity, rapid population growth, and climate change. Water scarcity is the lack of fresh water resources to meet the standard water demand. Although Sub-Saharan Africa has a plentiful supply of rainwater, it is seasonal and unevenly distributed, leading to frequent floods and droughts. Additionally, prevalent economic development and poverty issues, compounded with rapid population growth and rural-urban migration have rendered Sub-Saharan Africa as the world's poorest and least developed region.

The hiding hand principle is a theory that offers a framework to examine how ignorance intersects with rational choice to undertake a project; the intersection is seen to provoke creative success over the obstacles through the deduction that it is too late to abandon the project. The term was coined by economist Albert O. Hirschman.
