To create confidence in a result, several software packages should be applied to the same estimation problem. This study examines the results of three software packages (EViews, R, and Stata) in the analysis of time-series econometric data. The time-series data analysis which presents the determinants of macroeconomic growth of Sri Lanka from 1978 to 2020 has been used. The study focuses on testing for stationarity, cointegration, and significant relationships among the variables. The Augmented Dickey-Fuller and Phillips Perron tests were employed in this study to test for stationarity, while the Johansen cointegration test was utilized to test for cointegration. The study employs the vector error correction model to assess the short-run and long-term dynamics of the variables in an attempt to determine the relationship between them. Finally, the Granger Causality test is employed in order to examine the linear causation between the concerned variables. The study revealed that the results produced by three software packages for the same dataset and the same lag order vary significantly. This implies that time series econometrics results are sensitive to the software that is used by the researchers while providing different policy implications even for the same dataset. The present study highlights the necessity of further analysis to investigate the impact of software packages in time series analysis of economic scenarios.展开更多

Specifically, it separated the oil price fluctuations into positive and negative components, and modeled the return of industry portfolios with them. Next, the sensitivity of the airline industry to oil price was investigated to gauge the effectiveness of their hedging strategies, with the hope that the methodology can be extended to other industries. In addition, this paper explored the macroeconomic impact of oil price movements by examining the benchmarks such as GDP and CPI.展开更多

The contemporary crisis has shown the weakness of fiscal policy. With very low interest rates, the monetary policy does not seem to provide an alternative exit strategy out of the crisis, too. In this paper we discuss the hypothesis that GDP can still be a reliable estimate of growth. Nevertheless, at crisis times, only if the focus is on the foreign demand like International Tourism Receipts and Exports, and Exports can be an exit strategy. One component of Exports and International Tourism Receipts are worthy of attention. Thanks to a cluster analysis of per year variations of International Tourism Receipts (ITRs), GDP and Exports (World Bank Database) from 2007 to 2011, average positive variations of GDPs are matching with positive ITRs and Exports for “clusters” of countries. Performances of Europe and USA are worse than China, Brazil, India and South Africa and these continents and countries are separated in two different clusters. This result can be related to an increase of trade in emerging economies more than in mature ones, whose exit out of the crisis is much more demanding. The research confirms that Tourism and Exports are having an impact on the growth at different intensities (Europe and America vs. Asia) at crisis times.展开更多

On the other hand, the high quality buildings in Costa Rica have the same vulnerability as the reinforced concrete buildings in China due to the adoption of state-of-art techniques in design and construction, which represent the vulnerability of the best case. The macroeconomic vulnerability defined by Chen et al. falls in the middle of the two extreme cases of the inventory studied because the total macroscopic loss is the sum of losses of different types of buildings and facilities. Therefore the macroeconomic vulnerability must be greater than that of the best case and less than that of the worst. The use of macroscopic vulnerability in earthquake loss estimate is easy, simple and feasible. The vulnerability plots are preliminary in nature and should be refined with additional earthquake loss data.展开更多

Based on input-output tables of China in 2005 and2010,this paper gives a deep insight into the relationship between agriculture and national economy and its macroeconomic effects by the methods of input-output analysis,industrial correlation and macroeconomic effect analysis. The results show that the agricultural development is highly dependent on the national economy,but makes low contribution; agriculture contributes to promoting employment and improving the structure of national income distribution; despite the government's tax incentive,the agricultural equipments are updated slowly,and the corporate profits are at low level; agricultural export effect is far below the average industry level,but the import effect increases over the years,and final products are often used for domestic consumption. Finally,we set forth recommendations for improving the development of agriculture and national economy.展开更多

Methods employed include econometrics and model analysis. The results indicate that:( i) on the conditions that the equilibrium of supply and demand in land market,the modified IS-LM model taking into account land factor successfully performs transmission mechanism of land policy participation in macroeconomic-control by means of money capital regulation;( ii) the direction and intensity of land policy control are effected by elasticity of land supply and land price,meanwhile different characteristics of land supply elasticity exit in different stages of economic development;( iii) the realization of IS-LM equilibrium requires the aggregate effects of fiscal,monetary and land policy. It is concluded that land policies for macroeconomic-control drives land price higher,and land supply regulation would diminish financial effect. During the economic expansion or recovery period,the effect of expansionary land policy would be counteracted by high land price. During the economic transition or recession period,the government could control economical operation better through tightening land policy.展开更多
