Abstract We consider embedded, smooth curves in the plane which are either closed or asymptotic to two lines. study their behaviour under curve shortening flow with a global forcing term. prove an analogue Huisken’s distance comparison principle for initial whose local total curvature does not lie below $$-\pi $$ -</mm...

Abstract: In this paper, we establish existence of global subsonic and subsonic-sonic flows through infinitely long axially symmetric nozzles by combining variational method, various elliptic estimates and a compensated compactness method. More precisely, it is shown that there exist global subsonic flows in nozzles for incoming mass flux less than a critical value; moreover, uniformly subsonic...

In recent years, supporting intellectual property right has gained more significance. Intellectual property rights could be considered as legal rights resulting from intellectual activities in industrial, scientific, literary and artistic fields. Today, many countries are seeking practical information about using intellectual property to improve economic growth. Intellectual property rights hav...

This paper investigates the relation between mutual fund flows and the real economy. The findings of this paper support the theory that the positive co-movement of flows into equity funds and stock market returns is explained by a common response to macroeconomic news. Variables that predict the real economy as well as the equity premium – in particular dividend-price ratio, default spread, rel...

As a result of recent developments, global economic centre of gravity has slide to Asia-Pacific region. It is predicted that Asia-Pacific countries will take place at the first row in global trade and nearly a half of the total trade will intensify in this region at the year 2030. On the other hand, the region covers countries from different levels of development. These features of the region p...

Remittances can potentially help to promote economic development by providing a mechanism to share risks, reduce poverty and improve equality. However, from the viewpoint of economic theory the overall impacts of remittances are uncertain, as different mechanisms lead to opposite impacts. Since the 1990s Vietnam has experienced a dramatic growth in remittance flows from abroad. Vietnam is a uni...

Marginal-Cost (MC) tolls are known to produce economic efficiency of network flows. Yet, MC pricing has not been widely adopted, because of various perceived unpopular aspects, such as complexity, collection costs, and inequities. Minimal Revenue (MinRev) pricing has been suggested as a means to achieve most of the economic improvements of MC pricing with fewer unpopular aspects. One claimed im...

This paper studies the global variation in economic preferences. For this purpose, we present the Global Preference Survey (GPS), an experimentally validated survey dataset of time preference, risk preference, positive and negative reciprocity, altruism, and trust from 80,000 individuals in 76 countries. The data reveal substantial heterogeneity in preferences across countries, but even larger ...
