in recent years, it has become increasingly important to incorporate explicit dynamics in economic analysis. these two tools that mathematicians have developed, differential equations and optimal control theory, are probably the most basic for economists to analyze dynamic problems. in this paper i will consider the linear differential equations on the plane (phase diagram) and elements of nonl...

The paper deals with the consequences of an unequal wealth distribution on economic growth in developing countries. Understanding whether or not there is a trade-off between inequality and growth is fundamental in order to give the adequate attention to those policies that avoid increases in inequality, which may hurt overall growth. With the use of crosscountry regressions in the context of mo...

In the classic ultimatum game, for example, most people turn down financial gains by rejecting unequal monetary splits. The present study points to neglected individual differences in this debate. After participants played the ultimatum game we test...

Globally, health has improved for many but not for everyone equally. That food and nutrition-related health is unequally distributed is a marker of societal failure. For some individuals, communities and even nation...
