Economist.
Im sure
that the profession of an economist is one of the most important now days in
view of the situation in our Republic.

What makes
a good economist?Whatever he does, an economist should have a through training
in economist theory, mathemaics and statistics and the University well be
taught various general and special subjects,such as
Macroeconomics,Microeconomics,Manageicsment,Accounting,Statistics,Advertising,Money
and Banking,Economic Theory,Econometrics,Marketing,Computer Science,philosophy,Business
Ethnics,Foreign Languages,etc.

An
economist needs some knowledge of the world outside his own country because
both business and government are deeply involved in the world economy.Some
knowledge of political and economic history will help him to expect changes and
always look for basic long-run forces under the surface of things.

Being
employed in industry and business the graduates work as managers,as an
executive manager,a sales manager, a
financial manager.Some of us work as accountants.An account is one of the most
prestigious and widely required professions of an economist in and society.You
shouldnt mix an accountant and with a book-keeper.While a book-keeper is mostly
involved in calculations,like balance sheets,income statements,invoices,an
accountant is responsible for designing the financial policy of a company.

Some of us
work at the banks,at the Stock Exchange as brokers,other work for the
government or are employed by various
agencies and by military services.Knowing the economisc laws of the
society,economists can solve many problems facing our Rebublic and i hope ill manage to make my contribution to this
process.
