A significant number of intermediate age clusters (1 − 2 Gyr) in the Magellanic Clouds appear to have multiple stellar populations within them, derived from bi-modal or extended main sequence turn offs. If this is interpreted as an age spread, the multiple populations are separated by a few hundred Myr, which would call into question the long held notion that clusters are simple stellar populat...

The paper applies two commonly used methods in the literature to estimate shadow economy Malta, Currency Demand Approach and Multiple Indicator Causes (MIMIC) model. Given unobservable nature of economy, estimates are surrounded by a considerable degree uncertainty. While these differ somewhat on historical evolution size Maltese which turn can be traced back their different underlying assumpti...

Coordinated development between the economy and the environment is currently one of the most important issues in China. By establishing models concerning labor income share and hidden carbon emissions, and taking trade as the link in their relationship, this study puts forward the scale effects, technological effects, and structural effects that relate to labor income share under the function o...
