This chapter reviews the theory of the voluntary public and private redistribution of wealth elaborated by economic analysis in the last forty years or so. The central object of the theory is altruistic gift-giving, construed as benevolent voluntary redistribution of income or wealth. The theory...

In a general equilibrium model with a continuum of traders and bounded aggregate endowment, I investigate the Market Selection Hypothesis that markets favor traders with accurate beliefs. Contrary to known results for economies with (only) finitely many traders, I find that risk attitudes affect...

Son yıllarda iktisat yazınında disiplinler arası çalışmaların sayısı giderek artmaktadır. Bu ilginin altında, doğrusal ve statik modellere dayanan klasik iktisat teorisinin modellerinin, gerçekte kompleks/karmaşık özellik gösteren yapıları çözümlemede yetersiz kalması...

The number of interdisciplinary studies in the economics literature is increasing in the recent years. The reason for this increasing interest is the inadequecy of the linear and static models of classical economics for representing the complex structures of the real world. Economy is composed...

Traditional portfolio optimization models specify placement of capital as rather irrevocably and fully at risk through investment horizon(s) or continuously. Under this constraint, asset class allocation typically serves as primary mode of diversification, pursuing risk moderation by seeking to...

In finance, decision making and choice requires that we assume that asset prices tend to trend. This assumption also logically enables us to construct exits to limit losses and protect capital. But investors have good reason to be uneasy regarding the potential for significant loss when using a...

A system of thought allowed for the free market price of land to cyclically go down to zero. This is the economics of Moses. The economics of Jesus is a restatement of the economics of Moses. The first was applied during Biblical times and the latter, united with Aristotle’s thought and...

Multiplicity of equilibria is a common problem in many economic models. In general, it is impossible to devise methods that always find all equilibria for any type of model. A notable exception are models in which all equilibria are solutions to a system of polynomial equations since there are...

We reconsider the theory of Thompson aggregators proposed by Marinacci and Montrucchio (2010). We demonstrate the Koopmans equation has a unique utility function solution given a Thompson aggregator. Uniqueness holds only on the interior of the commodity space's positive cone. We verify Du's...
