Theoretical Unification in Justice and Beyond The goal of scientific work is to understand more and more by less and less. In this effort, theoretical unification plays a large part. There are two main types of theoretical unification – unification of different theories of the same field of phenomena and unification of theories of different fields of phenomena. Both types are usually a surprise...

Using a result in Angelini and Herzel (2009a), we measure, in terms of variance, the cost of hedging a contingent claim when the hedging portfolio is re-balanced at a discrete set of dates. We analyze the dependence of the variance of the hedging error on the skewness and kurtosis as modeled by a Normal Inverse Gaussian model. We consider two types of strategies, the standard Black-Scholes Delt...

This paper studies price dynamics in a setting in which a monopolist sells a new experience good over time to many buyers, and the seller can neither price discriminate among the buyers nor commit to a price rule. Buyers learn from their own experiences about the effectiveness of the product. Individual learning generates ex post heterogeneity, which affects the buyers’ purchasing decisions, th...

Given a financial network of liabilities, we consider the following question: which agent’s potential default would implicate the most number of agents in the network structure? Simply comparing each agent’s total debt completely ignores the structure of the network. For propagation effects of a potential default, owing to a creditor who does not owe anybody and owing to a creditor who is heavi...

A numerical method to price double-barrier options with moving barriers is proposed. Using the so-called Boundary Element Method, an integral representation of the double-barrier option price is derived in which two of the integrand functions are not given explicitly but must be obtained solving a system of Volterra integral equations of the first kind. This system of equations is affected by s...

Given a set of vector outcomes and the set of lotteries over it, we define sets of (a) von Neumann-Morgenstern representations of cardinal preferences over the lotteries, (b) mappings that yield the certainty equivalent outcomes corresponding to a lottery, (c) mappings that yield the risk premia corresponding to a lottery, (d) mappings that yield the acceptance set of lotteries corresponding to...

We study the mechanisms according to which social infrastructure influences the preservation of physical capital and, consequently, economic growth. The presented model considers that social infrastructure is a specific type of human capital, which acts in order to preserve already existing physical capital, by, e.g. reducing the incentive for rent seeking or corruption. Using an innovative met...

Given a set of possible vector outcomes and the set of lotteries over it, we define sets of (a) von Neumann-Morgenstern representations of preferences over the lotteries, (b) mappings that yield the certainty equivalent outcomes corresponding to a lottery, (c) mappings that yield the risk premia corresponding to a lottery, (d) mappings that yield the acceptance set of lotteries corresponding to...

JEL Classification Code(s): J 31, J 71) "Perceptions of Discrimination, Effort to Obtain Psychological Balance, and Relative Wages: Can We Infer a Happiness Gradient?" There is a substantial literature that finds a linkage between happiness and relative economic well being as measured by earnings or wages. There is also a well documented racial gap in wages. One explanation for this is disparat...
