Approximately half the world's population now has replacement-level fertility or below. The UK experience in accommodating to a changing dependency ratio provides some generalizable insights. A mechanistic approach assuming a fixed retirement age and a need to raise fertility or increase immigration in order to maintain pensions at a fixed proportion of the gross domestic product (GDP) is overs...

Time series of quarterly observations on Gross Domestic Product (GDP) is collected and used in this study. Forecasting results of ANNs are compared with those of the Autoregressive Integrated Moving Average (ARIMA) and regression as benchmark methods. Using Root Mean Square Error (RMSE), the empirical results show that ANN performs better than the traditional methods in forecasting GDP.

We propose a release-augmented dynamic factor model (RA-DFM) that allows to quantify the role of country's data flow in nowcasting both early Gross Domestic Product (GDP) releases and subsequent revisions official estimates. use RA-DFM study UK GDP revision rounds assemble comprehensive novel mixed-frequency dataset features 12 years real-time vintages. The improves over standard DFM real time ...

World capital ‡ows are substantial. Since 2000, gross world capital ‡ows have averaged about 25 percent of world GDP per year, while net capital ‡ows have been in excess of 4 percent of world GDP. Figure 1 shows these net ‡ows as a fraction of world gross domestic product (GDP) over this period. Robert Lucas (1990) presumed that poor countries would have higher marginal products of capital (MPK...

Newspaper advertising expenditures depend more strongly on economic development than advertising spent in other media. Gross domestic product (GDP), therefore, predicts ad spending better in countries where newspapers are an important advertising medium. GDP also predicts ad spending better in countries where a larger proportion of GDP is spent on advertising. Intermedia competition, on the oth...

WHO African region has got the highest maternal mortality rate compared to the other five regions. Maternal mortality is hypothesized to have significantly negative effect on the gross domestic product (GDP). The objective of the current study was to estimate the loss in GDP attributable to maternal mortality in the WHO African Region. The burden of maternal mortality on GDP was estimated using...

In this paper, the relationship between the Gross Domestic Product (GDP), air temperature variations and power consumption is evaluated using the linear regression and Wavelet Coherence (WTC) approach on a 1971-2011 time series for the United Kingdom (UK). The results based on the linear regression approach indicate that some 66% variability of the UK electricity demand can be explained by the ...

Logistics Industry is regarded as the artery and basal industry of country economic development. Its degree of the development is one of the symbols of modernization and comprehensive national strength, and is described as the accelerator on promoting economic development. By using economic analytical method, the article takes the gross domestic product (GDP) as the explained variable and the v...
