Unit Root Test Essay

...Stationary Test (Unit Root Test) Nelson and Plosser (1982) argue that almost all macroeconomic time series one typically uses have a unit root. The presence or absence of unit roots helps to identify some features of the underlying data generating process of a series. In the absence of unit root (stationary), the series fluctuates around a constant long-run mean and implies that the series has a finite variance which does not depend on time. On the other hand, non- stationary series have no tendency to return to the long-run deterministic path and the variance of the series is time dependent. Non-stationary series suffer permanent effects from random shocks and thus the series follows a random walk. If the series is non-stationary and the first...

The Effect of Savings Rate in Canada

...THE EFFECT OF SAVINGS RATE IN CANADA The impact of savings rate in an economic has become a very conflicting issue in research and among economist all over the world. This may be due to the importance of savings generally to the economic growth and development of any nation. However, the structure of every economy cannot be generalised by a particular economics’ variation because various countries have different social security and pension schemes, and different tax systems, all of which have an effect on disposable income. In addition, the age of a country’s population, the availability and ease of credit, the overall wealth, and cultural and social factors within a country all affect savings rates within a particular country. Therefore, this paper seeks to find the effect of savings in the Canadian economy. Household saving is defined as the difference between a household’s disposable incomes mainly wages received, revenue of the self-employed and net property income and its consumption (expenditures on goods and services). The household savings rate is calculated by dividing household savings by household disposable income. A negative savings rate indicates that a household spends more than it receives as regular income and finances some of the expenditure through credit (increasing debt), through gains arising from the sale of assets (financial or non-financial), or by running down cash and deposits. Since the early-to-mid-1990s, savings rates have been stable in some...

...CONSTRUCTION OF UNIT ROOT TESTS WITH GOOD SIZE AND POWER Serena Ng  Pierre Perron y This Draft: February 1998 It is widely known that when there are negative moving average errors, a high order augmented autoregression is necessary for unit root tests to have good size, but that information criteria such as the AIC and BIC tend to select a truncation lag that is very small. Furthermore, size distortions increase with the number of deterministic terms in the regression. We trace these problems to the fact that information criteria omit important biases induced by a low order augmented autoregression. We consider a class of Modi ed Information Criteria MIC, de ned as mink ln^ 2 + CT  T k + k=T, where T k accounts for the fact that the bias in k the sum of the autoregressive coe cients is highly dependent on k. Using a local asymptotic framework in which the root of an MA1 process is local to -1, we show that the MIC allows for added dependence between k and the number of deterministic terms in the regression. Most importantly, the k selected by the recommended MAIC with CT = 2 is such that both its level and rate of increase with the sample size are desirable for unit root tests in the local asymptotic framework, whereas the AIC, MBIC and especially the BIC with CT = lnT are less attractive in at least one dimension. In monte-carlo experiments, the MAIC is found to yield huge size improvements to the DF GLS and the feasible point optimal PT test developed in Elliott...

Success, no matter how big or small the goals are, can only be grasped through the attaining of those goals. Success must also be sought after. For anyone to have success, they must fight and strive for it. If a secretary of a large corporation worked her way up the ladder through hard work and sacrifice, she would be a success. On the other hand, if a secretary had a friend who got her a job at the top, she would not be looked upon as a success. There must be a desire for improvement and a commitment to achieve success. It cannot be handed out or paid for. If a student worked hard on homework, read the material, and did well on the test, they would be successful. The desire to...
