  A market economy is one where goods and services are produced and exchanged according to demand and supply between participants (economic agents) by barter or a medium of exchange with a credit or debit value accepted within the network, such as a unit of currency. A planned economy is one where political agents directly control what is produced and how it is sold and distributed. A green economy is low-carbon and resource efficient. In a green economy, growth in income and employment is driven by public and private investments that reduce carbon emissions and pollution, enhance energy and resource efficiency, and prevent the loss of biodiversity and ecosystem services. A gig economy is one in which short-term jobs are assigned or chosen on-demand. The global economy refers to humanity's economic system or systems overall. An informal economy is neither taxed nor monitored by any form of government.
