Economic policy in the context of "Arthashastra"

Regional policy is the sum of a series of policies formulated according to regional differences to coordinate regional relations and regional macro operation mechanism, which affects regional development at the macro level. It includes regional economic policy, regional social policy, regional environmental policy, regional political policy, regional cultural policy, etc. Regional policy aims to improve economic conditions in regions of relative disadvantage, either within a nation or within a supranational grouping such as the European Union. Additionally, a regional policy may try to address high levels of unemployment and lower-than-average per capita incomes. Its main tool is public investment.

Mercantilism is a form of economic system and nationalist economic policy that is designed to maximize the exports and minimize the imports of an economy. It seeks to maximize the accumulation of resources within the country and use those resources for one-sided trade.

The concept aims to reduce a possible current account deficit or reach a current account surplus, and it includes measures aimed at accumulating monetary reserves by a positive balance of trade, especially of finished goods. Historically, such policies may have contributed to war and motivated colonial expansion. Mercantilist theory varies in sophistication from one writer to another and has evolved over time.

A government budget is a projection of the government's revenues and expenditure for a particular period, often referred to as a financial or fiscal year, which may or may not correspond with the calendar year. Government revenues mostly include taxes (e.g. inheritance tax, income tax, corporation tax, import taxes) while expenditures consist of government spending (e.g. healthcare, education, defense, infrastructure, social benefits). A government budget is prepared by the Central government or other political entity. In most parliamentary systems, the budget is presented to the legislature and often requires approval of the legislature. The government implements economic policy through this budget and realizes its program priorities. Once the budget is approved, the use of funds from individual chapters is in the hands of government ministries and other institutions. Revenues of the state budget consist mainly of taxes, customs duties, fees, and other revenues. State budget expenditures cover the activities of the state, which are either given by law or the constitution. The budget in itself does not appropriate funds for government programs, hence the need for additional legislative measures.

A social issue is a problem that affects many people within a society. It is a group of common problems in present-day society that many people strive to solve. It is often the consequence of factors extending beyond an individual's control. Social issues are the source of conflicting opinions on the grounds of what is perceived as morally correct or incorrect personal life or interpersonal social life decisions. Social issues are distinguished from economic issues; however, some issues (such as immigration) have both social and economic aspects. Some issues do not fall into either category, such as warfare.

Exemplary for social issues was the so-called social question in the beginning of the industrial revolution. Growing poverty on one and growing population and materialistic wealth on the other hand caused tension between very rich and poorest people inside society.

Water scarcity (closely related to water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. There are two types of water scarcity. One is physical. The other is economic water scarcity. Physical water scarcity is where there is not enough water to meet all demands. This includes water needed for ecosystems to function. Regions with a desert climate often face physical water scarcity. Central Asia, West Asia, and North Africa are examples of arid areas. Economic water scarcity results from a 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. Many people in sub-Saharan Africa are living with economic water scarcity.

There is enough freshwater available globally and averaged over the year to meet demand. As such, water scarcity is caused by a mismatch between when and where people need water, and when and where it is available. This can happen due to an increase in the number of people in a region, changing living conditions and diets, and expansion of irrigated agriculture. Climate change (including droughts or floods), deforestation, water pollution and wasteful use of water can also mean there is not enough water. These variations in scarcity may also be a function of prevailing economic policy and planning approaches.

In macroeconomics and economic policy, a floating exchange rate (also known as a fluctuating or flexible exchange rate) is a type of exchange rate regime in which a currency's value is allowed to fluctuate in response to international events affecting exchange rates. A currency that uses a floating exchange rate is known as a floating currency. In contrast, a fixed currency is one where its value is specified in terms of material goods, another currency, or a group of other currencies. The idea of a fixed currency is to reduce currency fluctuations.

In the modern world, most of the world's currencies are floating, and include the majority of the most widely traded currencies: the United States dollar, the euro, the Japanese yen, the pound sterling, or the Australian dollar. However, even with floating currencies, central banks sometimes participate in markets to attempt to influence the value of floating exchange rates. The Canadian dollar has not seen interference by the Canadian national bank with its price since September 1998. The US dollar also sees very little change of its foreign reserves.

Protectionism, sometimes referred to as trade protectionism, is the economic policy of restricting imports from other countries through methods such as tariffs on imported goods, import quotas, and a variety of other government regulations. Proponents argue that protectionist policies shield the producers, businesses, and workers of the import-competing sector in the country from foreign competitors and raise government revenue. Opponents argue that protectionist policies reduce trade, and adversely affect consumers in general (by raising the cost of imported goods) as well as the producers and workers in export sectors, both in the country implementing protectionist policies and in the countries against which the protections are implemented.

Protectionism has been advocated mainly by parties that hold economic nationalist positions, while economically liberal political parties generally support free trade.
