Hartwick's Rule
In resource economics, Hartwick's rule defines the amount of investment in produced capital (buildings, roads, knowledge stocks, etc.) that is needed to exactly offset declining stocks of non-renewable resources. This investment is undertaken so that the standard of living does not fall as society moves into the indefinite future. Solow (1974) shows that, given a degree of substitutability between produced capital and natural resources, one way to design a sustainable consumption program for an economy is to accumulate produced capital sufficiently rapidly so that the pinch from the shrinking exhaustible resource stock is precisely countered by the services from the enlarged produced capital stock. Hartwick's rule – often abbreviated as "invest resource rents" – requires that a nation invest all rent earned from exhaustible resources currently extracted, where "rent" is defined along paths that maximize returns to owners of the resource stock. The rule extends to the case of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resource Economics
Natural resource economics deals with the supply, demand, and allocation of the Earth's natural resources. One main objective of natural resource economics is to better understand the role of natural resources in the economy in order to develop more sustainable methods of managing those resources to ensure their availability for future generations. Resource economists study interactions between economic and natural systems, with the goal of developing a sustainable and efficient economy. Areas of discussion Natural resource economics transdisciplinary field of academic research within economics that aims to address the connections and interdependence between human economies and natural ecosystems. Its focus is how to operate an economy within the ecological constraints of earth's natural resources.Encyclopedia of EarthArticle Topic: ecological economics/ref> Resource economics brings together and connects different disciplines within the natural and social sciences connected t ...

Investment
Investment is the dedication of money to purchase of an asset to attain an increase in value over a period of time. Investment requires a sacrifice of some present asset, such as time, money, or effort. In finance, the purpose of investing is to generate a return from the invested asset. The return may consist of a gain (profit) or a loss realized from the sale of a property or an investment, unrealized capital appreciation (or depreciation), or investment income such as dividends, interest, or rental income, or a combination of capital gain and income. The return may also include currency gains or losses due to changes in the foreign currency exchange rates. Investors generally expect higher returns from riskier investments. When a low-risk investment is made, the return is also generally low. Similarly, high risk comes with a chance of high losses. Investors, particularly novices, are often advised to diversify their portfolio. Diversification has the statistical effec ...

Capital (economics)
In economics, capital goods or capital are "those durable produced goods that are in turn used as productive inputs for further production" of goods and services. At the macroeconomic level, "the nation's capital stock includes buildings, equipment, software, and inventories during a given year." A typical example is the machinery used in factories. Capital can be increased by the use of the factors of production, which however excludes certain durable goods like homes and personal automobiles that are not used in the production of saleable goods and services. Adam Smith defined capital as "that part of man's stock which he expects to afford him revenue". In economic models, capital is an input in the production function. The total physical capital at any given moment in time is referred to as the capital stock (not to be confused with the share capital, capital stock of a business entity). Capital goods, real capital, or capital assets are already-produced, durable goods o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-renewable Resources
A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved (except in nuclear reactions, nuclear decay or atmospheric escape). Conversely, resources such as timber (when harvested sustainably) and wind (used to power energy conversion systems) are considered renewable resources, largely because their localized replenishment can occur within time frames meaningful to humans as well. Earth minerals and metal ores Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are present i ...

Robert Solow
Robert Merton Solow, GCIH (; born August 23, 1924) is an American economist whose work on the theory of economic growth culminated in the exogenous growth model named after him. He is currently Emeritus Institute Professor of Economics at the Massachusetts Institute of Technology, where he has been a professor since 1949. He was awarded the John Bates Clark Medal in 1961, the Nobel Memorial Prize in Economic Sciences in 1987, and the Presidential Medal of Freedom in 2014. Four of his PhD students, George Akerlof, Joseph Stiglitz, Peter Diamond and William Nordhaus later received Nobel Memorial Prizes in Economic Sciences in their own right. Biography Robert Solow was born in Brooklyn, New York, into a Jewish family on August 23, 1924, the oldest of three children. He regarded his parents as being very intelligent despite their not being able to attend college due to the necessity to work. He was well educated in the neighborhood public schools and excelled academically early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Consumption
Sustainable consumption (sometimes abbreviated to "SC") is the use of products and services in ways that minimize impacts on the environment in order for human needs to be met in the present but also for future generations. Sustainable consumption is often paralleled with sustainable production; consumption refers to use and disposal (or recycling) not just by individuals and households, but also by governments, businesses, and other organizations. Sustainable consumption is closely related to sustainable production and sustainable lifestyles. "A sustainable lifestyle minimizes ecological impacts while enabling a flourishing life for individuals, households, communities, and beyond. It is the product of individual and collective decisions about aspirations and about satisfying needs and adopting practices, which are in turn conditioned, facilitated, and constrained by societal norms, political institutions, public policies, infrastructures, markets, and culture." The United Natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Capital
Natural capital is the world's stock of natural resources, which includes geology, soils, air, water and all living organisms. Some natural capital assets provide people with free goods and services, often called ecosystem services. All of these underpin our economy and society, and thus make human life possible. It is an extension of the economic notion of capital (resources which enable the production of more resources) to goods and services provided by the natural environment. For example, a well-maintained forest or river may provide an indefinitely sustainable flow of new trees or fish, whereas over-use of those resources may lead to a permanent decline in timber availability or fish stocks. Natural capital also provides people with essential services, like water catchment, erosion control and crop pollination by insects, which in turn ensure the long-term viability of other natural resources. Since the continuous supply of services from the available natural capital as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disinvestment
Disinvestment refers to the use of a concerted economic boycott to pressure a government, industry, or company towards a change in policy, or in the case of governments, even regime change. The term was first used in the 1980s, most commonly in the United States, to refer to the use of a concerted economic boycott designed to pressure the government of South Africa into abolishing its policy of apartheid. The term has also been applied to actions targeting Iran, Sudan, Northern Ireland, Myanmar, Israel, and China. Examples Industries * Global Climate Coalition – Ford, General Motors, Texaco, Southern Company, Exxon, and other corporate members of the Global Climate Coalition – an industry group opposing the Kyoto Protocol – were the target of a national divestment campaign run by Ozone Action in 2000. According to ''The New York Times'', when Ford Motor Company left the coalition, it was "the latest sign of divisions within heavy industry over how to respond to global warm ...

World Bank
The World Bank is an international financial institution that provides loans and grants to the governments of low- and middle-income countries for the purpose of pursuing capital projects. The World Bank is the collective name for the International Bank for Reconstruction and Development (IBRD) and International Development Association (IDA), two of five international organizations owned by the World Bank Group. It was established along with the International Monetary Fund at the 1944 Bretton Woods Conference. After a slow start, its first loan was to France in 1947. In the 1970s, it focused on loans to developing world countries, shifting away from that mission in the 1980s. For the last 30 years, it has included NGOs and environmental groups in its loan portfolio. Its loan strategy is influenced by the Sustainable Development Goals as well as environmental and social safeguards. , the World Bank is run by a president and 25 executive directors, as well as 29 various vice ...

Sustainability
Specific definitions of sustainability are difficult to agree on and have varied in the literature and over time. The concept of sustainability can be used to guide decisions at the global, national, and individual levels (e.g. sustainable living). Sustainability is commonly described as having three dimensions (also called pillars): environmental, economic, and social. Many publications state that the environmental dimension (also called "planetary integrity" or "ecological integrity") is the most important, and, in everyday usage, "sustainability" is often focused on countering major environmental problems, such as climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution. Humanity is now exceeding several "planetary boundaries". A closely related concept is that of sustainable development, and the terms are often used synonymously. However, UNESCO distinguishes the two thus: "''Sustainability'' is often thought of as a lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
