Economists can study various cultural and governmental models such as how one religion believes resources should be allocated or a form of government, such as democracies and majority rule.
Economics can be shaped by the political process, and the market can be influenced by the psychology of individuals who buy stocks.
An economist may study the implications of a new policy on a country's financial health and how certain groups may respond.
