In the case of a VAR process, each series can be estimated by the least square method or by another method e. The VAR process parameters can be estimated only by starting from stationary time series. Thus, after the study of series characteristics, these are either stationarized by differentiation, before estimating the parameters, in the case of DS series with random tendency , or a component of trend type is added in VAR specification, in the case of a deterministic trend. VAR analysis is finalized into three types of results: impulse response function, forecast error variance decomposition and Granger causality.

The impulse response function IRF traces the effect of a shock of a standard deviation of the residuals of a variable on the current values and on the future evolution of all other variables in the model. The variance decomposition VD provides information on the relative importance of each shock in the hierarchy of the effects on the variables in the system.

As the innovations cannot be anticipated, forecast errors are induced in the variables of interest. VD represents a calculation of the share in the total of these variations that is due to shocks coming from each variable. The Granger causality GC tests reveal what variables are useful for the forecast of other variables. We can state that X causes Granger on Y if a Y forecast made on the basis of a set of information that includes the history of X is better than a forecast that ignores the history of X.

In order to test whether X is a cause for Y in Granger sense, the regression equation is estimated: Where k is fixed so that errors are white noise. The tested hypotheses are the following: X is not the cause for Y, The testing of null hypothesis is based on the Fisher-Snedecor test. The null hypothesis is rejected if the value calculated for F statistics is higher than the critical value.

In order to test whether Y is a cause for X in Granger sense, the regression equation is estimated: The tested hypotheses are the following: Y is not cause for X, The testing of null hypothesis is based on the Fisher-Snedecor test. Following the application of the two tests, the following conclusions are possible: a. Unidirectional causality: X is cause for Y XY , if the null hypothesis is rejected at i and is accepted at ii; b.

Unidirectional causality: Y is cause for X Y X , if the null hypothesis is rejected at ii and is accepted at i; c. Bidirectional causality: XY, if the null hypothesis is rejected both at i and at ii; d. The two variables are independent if the null hypothesis is accepted at i and ii. The variables, data sources and descriptions used in the econometric estimates are presented below: Imports of agricultural products from developing countries, millions of lei.

The series are expressed in the average prices of The imports of agricultural products from developing countries I deflated by unit value indices of international trade, the exchange rate I deflated by CPI and the domestic demand I deflated by the corresponding price index.

The existence of a significant seasonal component was determined for all variables. For the three variables included in the study testing the integration order was made through two procedures: the Augmented Dickey-Fuller test and the Phillips-Perron test. The variables are integrated of order I, which is consistent with a first difference stationary representation Table 2. Look at the latest market trends, news, technical and fundamental analysis, and expert opinion before making any investment decision.

Keep in mind that past performance is no guarantee of future returns, and never invest money that you cannot afford to lose. FAQs Is gold a good investment? Some investors might opt to keep some exposure to gold in their portfolio for diversification, as a hedge against a fall in stocks and bonds. However, whether gold is a suitable investment for you depends on your risk tolerance, outlook for the market and whether you expect it to rebound or fall further, among other factors.

Always do your own research and remember that past performance is no guarantee of future returns. Never invest money that you cannot afford to lose. Will gold go up or down in ? The outlook for the gold price will likely depend on how geopolitical tensions unfold and how monetary tightening affects the global economy, among other factors.

Keep in mind that analysts can and do get their predictions wrong. You should do your own research to make informed trading decisions, always bearing in mind that past performance is no guarantee of future returns. Should I invest in gold? That depends on your view of the commodity.

Prognoze si analyze forex charts | The trendof the national economy opening is the result of many factors, among which we mention: the policies for the liberalization of foreign trade, by pronounced as possible opening of the economy to global markets, by the re-division of markets amidthe globalization and regionalization processes. Throughout the periodRomania registered trade surplus with developing countries in the following product categories: live animals; oil seeds and oleaginous fruits; miscellaneous grains; seeds and fruit; industrial or medicinal plants; straw and fodder and dairy produce; eggs; honey; edible animal products. As such, analysts and algorithm-based forecasters can and do get their predictions wrong. That depends on your view of the commodity.
