What factors might contribute to a low or high growth rates in a country? There are three categories of factors that contribute to a low or high growth rates. These categories are the demand factor‚ the efficiency factor‚ and supply factors. Government spending or exports can lead to a higher to aggregate demand and higher economic growth. “Economic growth requires increases in total spending to realize the output gain made available by increased production capacity” (McConnell‚ 2012‚ p. 513)

The methodology of this study is use Augmented Dickey Fuller (ADF) test statistic to determine whether the variables had been used are stationary or non-stationary. Vector Auto Regression (VAR) method is apply in this study. The advantages of VAR is time series can be exhibited at the same time. The VAR methodology is revises for autocorrelation and endogeneity parametrically using vector error correction model (VECM) specification. Base on Johansen (1988; 1995)‚ the benefit of VECM is that it prevents

Answers to Midterm Test No. 1 1. Consider a regression model of relating Y (the dependent variable) to X (the independent variable) Yi = (0 + (1Xi+ (i where (i is the stochastic or error term. Suppose that the estimated regression equation is stated as Yi = (0 + (1Xi and ei is the residual error term. A. What is ei and define it precisely. Explain how it is related to (i. ei is the residual error term in the sample regression function and is defined as eI hat = Y

Interest Rates An interest rate is the rate at which interest is paid by borrowers for the use of money that they borrow from a lender. Specifically‚ the interest rate is a percent of principal paid a certain amount of times per period. Small companies often borrow capital from banks to buy new assets for its business‚ and in return the lender receives interest at a predetermined interest rate for deferring the use of funds and instead lending it to the borrower. Interest rates are

are several different types of unemployment that we encountered through out these few chapters. They are as follows; structural unemployment‚ frictional unemployment‚ and cyclical unemployment. But yet each one is different in its own unique way. Cyclical unemployment is a factor of overall unemployment that relates to the cyclical trends in growth and production that occur within the business cycle. When business cycles are at their peak‚ cyclical unemployment will be low because total economic

interest rates. The RBA generally likes to keep inflation between the 2-3% mark‚ however‚ this may change as a result of international pressures. Generally‚ if inflation is seen to be increasing at a rate that is disproportionate to the health of the economy - or basically growing faster than it can sustain - then official rates may be raised to in order to reduce consumer spending and slow down the economy. Alternatively‚ if inflation is not increasing at a healthy rate‚ the official rate may be
