Several studies of the post-war American political economy find that Democratic presidents have been more successful than Republicans. Most recently, Bartels (2008) found that economic growth had been greater and that unemployment and income inequality had been lower under Democratic presidents since 1948. If true, these findings combined with the frequent success of Republicans in presidential...

A deterministic model based on the gene flow method, considering the features of Iranian Holstein cattle population, was implemented in this study to evaluate the effect of altering the number of age-classes in the dams of future sire (DS) path and the number of dams required for breeding a young bull (YB), to be evaluated as future sire, on genetic gain and resultant economic efficiency of a g...

Mapping apps are the greatest game-changer for encouraging people to explore the city. You take your phone out and you know immediately where to go. However, the app also assumes there are only a handful of directions to the destination. It has the power to make those handful of directions the definitive direction to that destination. A few years ago, my research started to focus on understandi...

The main objective of this study is to investigate the causal relationship between tourism development and economic growth in Gulf Cooperation Council (GCC) countries in a multivariate model, using panel data for the period 1995–2012. The study adopts a panel Granger causality analysis approach to assess the contribution of tourism to economic growth in GCC countries as a whole, and in each ind...

OBJECTIVE To understand caregivers' perceptions of children's linear growth and to identify the cultural meanings and perceptions of risk associated with poor height attainment. DESIGN Three investigators from Bangladesh conducted twelve focus group discussions. SETTING The study was conducted in rural and slum settings in Bangladesh. SUBJECTS Participants included mothers and alternative...

We develop a one-sector endogenous growth model in which renewable natural resources are both a factor of production and measure of environmental quality. Along the balanced growth path, sustained economic growth and a non-deteriorating environment are shown to coexist. Moreover, steady-state economic growth and natural-resource utilization are positively related. Empirically, a cross-country g...

R ecent years have seen an unprecedented number of official efforts to improve, develop, and implement new measures of the quality of life and economic performance. Much of the groundwork for these efforts was laid in two important National Research Council reports. Nature's Numbers, published in 1999, considered how to expand the national income accounts that track the country's economic activ...

The recent empirical growth literature has proposed three underlying fundamental determinants of economic growth, namely, physical geography, economic integration and institutional quality. This paper unpacks the final determinant into both political-economic institutions as well as the primarily political institution of democratic development. Using both cross-sectional and panel datasets, we ...

We deal with different algorithmic questions regarding properly arc-colored s-t trails, paths and circuits in arc-colored digraphs. Given an arc-colored digraph D with c ≥ 2 colors, we show that the problem of determining the maximum number of arc disjoint properly arc-colored s-t trails can be solved in polynomial time. Surprisingly, we prove that the determination of a properly arc-colored s-...
