Answer:
A. sells treasury securities increasing interest rates, leading to a stronger dollar that lowers net exports in an open economy.
Step-by-step explanation:
The Federal Reserve System ( popularly referred to as the 'Fed') was created by the Federal Reserve Act, passed by the U.S Congress on the 23rd of December, 1913. The Fed began operations in 1914 and just like all central banks, the Federal Reserve is a United States government agency.
Generally, it comprises of twelve (12) Federal Reserve Bank regionally across the United States of America.
Like all central banks, the Federal Reserve is a government agency that is saddled with the following responsibilities;
I. The Fed controls the issuance of currency in United States of America: it promotes public goals such as economic growth, low inflation, and the smooth operation of financial markets.
II. It provides banking services to all the commercial banks in the country because the Federal Reserve is the "lender of last resort."
III. It regulates banking activities in the United States of America: it has the power to supervise and regulate banks.
Fiscal policy in economics refers to the use of government expenditures (spending) and revenues (taxation) in order to influence macroeconomic conditions such as Aggregate Demand (AD), inflation, and employment within a country. Fiscal policy is in relation to the Keynesian macroeconomic theory by John Maynard Keynes.
A fiscal policy affects combined demand through changes in government policies, spending and taxation which eventually impacts employment and standard of living plus consumer spending and investment.
Generally, the government of a particular country could use a contractionary policy to slow down the economy when inflation is high and gross domestic product (GDP) is growing too.
Hence, when the Federal reserve (government) of the United States of America uses contractionary monetary policy to reduce inflation, it sells treasury securities at an increasing (high) interest rates, which eventually leads to a stronger dollar that lowers net exports (total trade) in an open economy.
