The gravity flow dynamics of submarine fan sedimentation in the Magura Basin of the Western Carpathians (Magura Nappe, Slovakia)

This article deals with the dynamics of the deep-water gravity flows sedimentation within the Magura Formation. This investigation is based on analysis of the Magura sandstone sedimentary structures studied on the outcrops. The final comparison of the sedimentary structures and cycles with the paleocurrent directions provided an interpretation of the gravity flows dynamics and helped to restore the migration of the sandy lobes in space and time. Three modes of sedimentation are recorded: regular cyclic sedimentation from the lobe, irregular sedimentation from the immature lobe and pelitic sedimentation on the basin plane without the lobe influence. We compared the occurrence of some sedimentary structures with the changes of the current directions and bed thickness. The following interpretations of gravity flow fan dynamics are results of this comparision: the fan consists of one or several lobes, the lobe branches out into branches with the radial current arrangement, the lobes laterally change position and the lobes suddenly die out.

Abstract

The paper examines from an empirical point of view the state of economic sustainability of Romania on the period 2007 - 2017. To this end, a set of macroeconomic indicators for sustainability was used. To be mentioned this set of indicators is elaborated within The Centre for Financial and Monetary Research "Victor Slăvescu", in its annual publication named "Financial stance of Romania". Although the obtained results in the past are coherent with the main macroeconomic dynamics on the analysed period, it seems that these results must be correlated with the so-called cyclical position of the economy, but this analysis will be done in the future. The study puts into evidence the importance of sustainability analyses in addition to the usual descriptive analyses, because they indicate not only the macroeconomic evolution, but also the national economy tendencies from the sustainability perspective.

Abstract

This paper explores the patterns of aggregate cyclical behavior within the Middle East and North Africa region and among this region and the major industrialized economies. We seek to determine how the volatility and the symmetry of MENA countries have been modified following their recent liberalization initiatives. In particular, we ask the broad question of how far the MENA zone can “couple” with the most developed economies and maintain a relative synchronicity with the world business cycle over 1970-2010. The Hodrick-Prescott filter is applied to decompose the real GDP of these countries and obtain the resulting series of cyclical components. These are compared at different time horizons: the contemporary, short-term, and long-term. Two approaches are used: a static one, based on properties of variability, co-variation and correlation, and a dynamic one, based on long-term relationships using an autoregressive distributed lag models and short-term dynamics using an error correction models. A long-term convergence between the MENA, the G7, the European, and the Anglo-Saxon cycles is confirmed particularly during 1989-2010, period under which the MENA countries have engaged an important economic integration process. This could denote a coupling of the region with the industrialized nations. The idiosyncratic cycles of the MENA countries are closely associated with the G7 experience, especially, in long term. While the European cycle has an important effect on the North African countries, the Middle East region is rather more dominated by the Anglo-Saxon zone.

Abstract

In this paper we analyse the monetary policy of the National Bank of Romania during 2005-2015 by estimating the Taylor rule, on a quarterly basis. We determined the potential GDP by employing the Hodrick-Prescott filter, in order to distinguish between the cyclical and the structural components of the output. Then, we estimated the traditional Taylor rule function (with a classic OLS regression), but slightly modified, as to take into account the forward-looking attitude of the NBR. The results confirm the direct correlation between the monetary policy rate and the output gap on the one hand, and the inflation differential (inflation - inflationtarget) on the other hand. Also, the results show us that NBR paid a higher attention to the dynamics of the inflation versus its target than to the output gap. Last, but not least, the central bank has been also sensitive to the financial stability, as reflected by the results of the incorporation of the ROBOR-EURIBOR spread in the classical Taylor rule.
