Context paragraphs:
Capital District, New York: The Capital District, also known as the Capital Region, refers to the metropolitan area surrounding Albany, the capital of the U.S. state of New York.  With a population of 1,170,483 (2013), the Capital District is the fourth largest metropolitan region in the state and the 45th largest in the country.  Companies that have headquarters in Albany include CommerceHub and the Environment One Corporation.  In the 21st century, the Capital District has emerged as a major anchor of Tech Valley, the moniker describing the technologically-focused region of eastern New York State.  The Capital District was first settled by the Dutch in the early 17th century and came under British control in 1664.  Albany has been the permanent capital of the state of New York since 1797.  The Capital District is notable for many historical events that predate the independence of the United States, including the Albany Plan of Union and The Battles of Saratoga.

Capital Consumption Allowance: The Capital Consumption Allowance (CCA) is the portion of the gross domestic product (GDP) which is due to depreciation.  The Capital Consumption Allowance measures the amount of expenditure that a country needs to undertake in order to maintain, as opposed to grow, its productivity.  The CCA can be thought of as representing the wear-and-tear on the country's physical capital, together with the investment needed to maintain the level of human capital (e.g. to educate the workers needed to replace retirees).

Rome: Rome ( ; Italian: "Roma" ] , Latin: "Rōma" ) is the capital of Italy and a special comune (named "Comune di Roma Capitale").  Rome also serves as the capital of the Lazio region.  With 2,877,215 residents in 1285 km2 , it is also the country's most populated comune.  It is the fourth-most populous city in the European Union by population within city limits.  It is the center of the Metropolitan City of Rome, which has a population of 4.3 million residents.  Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber.  The Vatican City is an independent country inside the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states.

Saint Lucia: Saint Lucia ( ; French: "Sainte-Lucie" ) is a sovereign island country in the eastern Caribbean Sea on the boundary with the Atlantic Ocean.  Part of the Lesser Antilles, it is located north/northeast of the island of Saint Vincent, northwest of Barbados and south of Martinique.  It covers a land area of 617 km (238.23 sq mi) and reported a population of 165,595 in the 2010 census.  Its capital is Castries.

Zaccheus Polius: Zaccheus Polius (born 14 June 1986) is a Saint Lucian international footballer who plays as a striker.

Maseru: Maseru is the capital and largest city of Lesotho.  It is also the capital of the Maseru District.  Located on the Caledon River, Maseru lies directly on the Lesotho-South Africa border.  Maseru is Lesotho's capital city with a population of approximately 253,000.  The city was established as a police camp and assigned as the capital after the country became a British protectorate in 1869.  When the country achieved independence in 1966, Maseru retained its status as capital.  The name of the city is a Sesotho word meaning "red sandstones".

Capital city: A capital city (or simply capital) is the municipality exercising primary status in a country, state, province, or other administrative region, usually as its seat of government.  A capital is typically a city that physically encompasses the offices and meeting places of its respective government; the status as capital is often designated by its law or constitution.  In some jurisdictions, including several countries, the different branches of government are located in different settlements.  In some cases, a distinction is made between the official (constitutional) capital and the seat of government, which is in another place.

Balance of payments: The balance of payments, also known as balance of international payments and abbreviated B.O.P., of a country is the record of all economic transactions between the residents of the country and the rest of the world in a particular period (over a quarter of a year or more commonly over a year).  These transactions are made by individuals, firms and government bodies.  Thus the balance of payments includes all external visible and non-visible transactions of a country.  It is an important issue to be studied, especially in international financial management field, for a few reasons.  First, the balance of payments provides detailed information concerning the demand and supply of a country's currency.  For example, if Mauritius imports more than it exports, then this means that the supply of rupees is likely to exceed the demand in the foreign exchanging market, "ceteris paribus".  One can thus infer that the Mauritius rupee would be under pressure to depreciate against other currencies.  On the other hand, if Mauritius exports more than it imports, then the rupee would be likely to appreciate.  Second, a country's balance-of-payment data may signal its potential as a business partner for the rest of the world.  If a country is grappling with a major balance-of-payment difficulty, it may not be able to expand imports from the outside world.  Instead, the country may be tempted to impose measures to restrict imports and discourage capital outflows in order to improve the balance-of-payment situation.  On the other hand, a country experiencing a significant balance-of payment surplus would be more likely to expand imports, offering marketing opportunities for foreign enterprises, and less likely to impose foreign exchange restrictions.  Third, balance-of-payments data can be used to evaluate the performance of the country in international economic competition.  Suppose a country is experiencing trade deficits year after year.  This trade data may then signal that the country's domestic industries lack international competitiveness.  To interpret balance-of-payments data properly, it is necessary to understand how the balance of payments account is constructed.

Capital deepening: Capital deepening is a situation where the capital per worker is increasing in the economy.  This is also referred to as increase in the capital intensity.  Capital deepening is often measured by the rate of change in capital stock per labour hour.  Overall, the economy will expand, "and" productivity per worker will increase.  However, according to some economic models, such as the Solow model, economic expansion will not continue indefinitely through capital deepening alone.  This is partly due to diminishing returns and wear & tear (depreciation).  Investment is also required to increase the amount of capital available to each worker in the system and thus increase the ratio of capital to labour.  In other economic models, for example, the AK model or some models in endogenous growth theory, capital deepening can lead to sustained economic growth even without technological progress.  Traditionally, in development economics, capital deepening is seen as a necessary but not sufficient condition for economic development of a country.

Capital flight: Capital flight, in economics, occurs when assets or money rapidly flow out of a country, due to an event of economic consequence.  Such events could be an increase in taxes on capital or capital holders or the government of the country defaulting on its debt that disturbs investors and causes them to lower their valuation of the assets in that country, or otherwise to lose confidence in its economic strength.
