This research confirms the great importance of oil and its impact on international relations
at the political and economic levels, which drives the major countries, especially the
United States of America, to secure the necessary oil supplies perma
nently and in any way
possible. The research aims to introduce the most important pillars of US oil policy and the
importance of protecting the oil security belt In general and the Gulf in particular, and the
development of the means followed by the United States to control and exploit the Gulf oil
as far as possible, both through the signing of the agreements of monopoly and even access
to the policy of waging wars or making crises, as research refers to the political and
economic history of the American exploitation of the Gulf oil despite the prevailing belief
that the United States is a strategic ally of the Gulf states. The research founded many
results and made some recommendations.
This paper aims to examine the relationship between stock prices and
macroeconomic variables in the United States using quarterly data for the period
1988 to 2012. We dentify five macroeconomic variables ( i.e, gross domestic
product, inflation, r
eal money supply, Treasury bill rate, and oil prices) that
researchers have linked to stock prices. We then examine the relationship
between these macroeconomic variables and the S&P500 by estimating
cointegration system using Johansen technique. Moreover, this paper will use
Vector Error Correction Model (VECM) to test the short run relationships. Also,
we use variance decomposition technique to understand which macroeconomic
variable have more explantory power of the variation in the S&P500.
The President of the United States of America has a veto, power which
means that he can veto a bill passed by the Congress, preventing it from
becoming law unless each house then re-passes the bill by a two-thirds majority.
The veto power vested i
n the President by Article I, Section 7 of the
Constitution has proved to be an effective tool for the Chief Executive in his
dealings with Congress.
The most important of all the checks and balances of the United States of
America Constitution is, of course, the presidential veto.
