In the current paper we propose to distinguish between micro and aggregate Laffer functions. We prove that in spite of the fact that a Laffer curve of any representative individual may have one peak point where tax revenue is at its maximum, the aggregate Laffer curve is more likely to have...

Two new normative indices of mobility are proposed. The first one is a population weighted generalized Gini mobility index and will be higher, the higher the size of the transfer between two individuals and, for a given transfer, the higher the rank difference between the individuals between...

This paper uses the Watts poverty index in order to derive a breakdown of poverty into chronic and transitory poverty. Following a paper by Chakravarty et al. (2008), we then suggest a new decomposition of these two components. Using the new decomposition, we are able to analyze the contribution...

A large reservoir of frozen human embryos is a negative outcome of their cryostorage for in vitro fertilization treatments. The existence of unused stored embryos, referred to herein as "remaining embryos", places the service provider (usually a hospital) in a fragile situation. This is...

The demand for security depends on several socioeconomic characteristics such as income, property, family size that may affect the demand for pure public security or private security. In the case of a homogeneous population, the identical demands lead to an equal use of the shared public good...

As our trading world becomes more globalized, who benefits and who gets hurt? This paper relies on the Ricardian model to explore the effects of technological improvements in underdeveloped countries on the welfare of developed countries. For example, trading between the United States and China,...

Classical theory of international trade has long advocated trade liberalization and open borders. However, this process is not necessarily beneficial to all countries involved. This paper focuses on two modeled economies that initially share the same technology and per-capita income, but differ...

Will all countries gain from free trade? Two countries, one with a large and the other a small population, are modeled. Once trade is opened, real income rises in the small country and falls in the large one. The intuition is that, without trade, the large country's local monopoly makes profits...

Given a world consisting of two countries, two commodities, and two consumers, this paper analyzes the potential effects of the current global trend of shifting world productions with regards to consumer goods. When technological improvements occur in a developing country, would terms of trade...
