Yearly Data

The time series yearly data for Gross Domestic Product (GDP), inflation and unemployment from 1980 to 2012 was used in the study. First difference of the logged data became stationary as suggested by the time series plots. Johansen Maximum Likelihood Cointegration test indicated a long-run relationship among the variables. Granger Causality tests suggested unidirectional causality between inflation and GDP, implying that GDP is Granger caused by inflation in Zimbabwe. Another unidirectional causality was noted between unemployment and inflation. The causality between unemployment and inflation imply that unemployment do affect GDP indirectly since unemployment influences inflation which in turn positively affect GDP.

Purpose This study aims to investigate the influence of systemic banking crises, currency crises and global financial crisis on the relationship between export and economic growth in China by using the annual time series data from the period of 1972 to 2014. Design/methodology/approach The Johansen and Jeuuselius’ cointegration, auto regressive distributed lag bound testing cointegration, Gregory and Hansen’s cointegration and pooled ordinary least square techniques with error correction model have been used. Findings Results indicate the positive and significant effect of export of goods and services on economic growth in both long and short run, whereas the negative influence of systemic banking crises and currency crises over economic growth is observed. It is also concluded that the impact of export of goods and service on economic growth becomes insignificant in the presence of systemic banking crises and currency crises. The currency crises effect the influence of export on economic growth to a higher extent compared to systemic banking crises. Surprisingly, the export in the period of global financial crises has a positive and significant influence over economic growth in China, which conclude that the global financial crises did not drastically affect the export-growth nexus. Originality/value This paper makes a unique contribution to the literature with reference to China, being a pioneering attempt to investigate the effects of systemic banking crises and currency crises on the relationship of export and economic growth by using long-time series data and applying more rigorous econometric techniques.

Abstract. We studied time-series fluxes of diatom particles from 4 October 2010 to 18 September 2012 using bottom-tethered moorings with two sediment traps deployed at 180 and 1300 m depths at Station NAP (75° N, 162° W; 1975 m water depth) in the western Arctic Ocean. This paper discusses on the relationship of time-series diatom fluxes to satellite-based sea-ice motion and simulated hydrographic variations. We observed clear maxima of the diatom valve flux in November–December of both 2010 and 2011, and in August 2011. Diatoms in samples were categorized into 98 taxa. The diatom flux maxima were characterized by many resting spores in November–December and by the sea-ice-associated diatom Fossula arctica in August 2011. These assemblages along with abundant clay minerals in the samples suggest a significant influence of shelf-origin materials transported by mesoscale eddies, which developed along the Chukchi Sea shelf break. In contrast, the fluxes of total mass and diatoms were reduced in summer 2012. We hypothesize that this suppression reflects the influx of oligotrophic water originating from the central Canada Basin. A physical oceanographic model demonstrated that oligotrophic surface water from the Beaufort Gyre was supplied to Station NAP from December 2011 to the early half of 2012.

The situation and efficiency of R & D activities in Hungary were analysed with the use of Eurostat and Central Statistical Office data. The conclusion was drawn that the system of indexes used and published officially is hardly suitable for presenting the existing problems and for carrying out strategic analyses. The analysis of the official data leads to the conclusion that it would be advisable to use long statistical time series and to apply indexes showing specific development more extensively. The situation of R & D in Hungary is presented in the paper from this approach. We have found that certain problems hindering R & D in Hungary, such as the insufficient concentration of researches, the insufficient proportion of business-like researches and researches promising direct economic benefits in general, the problems of the distribution of research investments between fields of science etc., could not be solved in the period after the change of the regime, either. In many respects the current situation of R & D is definitely worse than before the change of the regime, first of all as concerns the financing of R & D. The dominance of publication-centeredness as one of the approaches indicating efficiency may overshadow the fundamental duality in the relationship of R & D with economy, namely that economy should be not only the source but also the primary beneficiary of R & D activities.

The problem of child labor has long been studied by economists, and most of it focuses on the microeconomic perspective. For this study, the researchers have decided to shift their focus to macroeconomic analysis. This study focuses on the effects of globalization and economic growth on the prevalence of child labor in the Philippines, mainly focusing on globalization, by using time-series analysis. Studies suggested that there is an inverted U-shaped relationship between globalization and child labor in developing countries, while other studies have determined a U-shaped relationship. The findings of this study reveal that there is no U-shape relationship between the variables but instead follows a linear relationship between globalization and child labor in the Philippine context. However, the lack of data and research publication on a national scale could influence the empirical results. Furthermore, this research can be used as literature in future studies.

The aim of this research is to analyze the relationship of causality between oil prices, stocks market, and exchange rates in Indonesia using VAR model. The data used in this study is time series data from January 2014 until December 2018 that was obtained from the relevant institutions. The variables use are oil prices (X1), stocks market (X2), and exchange rates (X3). The method used in this study is Vector Auto Reggression (VAR). The finding has shown that there are no causality relationship between the oil prices, stock markets, and exchanger rates. The finding also shown that there is only directional relationship between exchange rates with stocks market.
