Ex Post Efficient Set Mathematics
This paper considers efficient set mathematics for the case where the covariance matrix of asset returns is assumed known but ex ante the vector of expected returns is replaced by an estimated or forecast value. It is shown that the ex post mean and variance differ from the standard results. Consequently the maximum Sharpe ratio portfolio also differs from the standard result. However, even wit...
متن کاملOn Efficient Partnership Dissolution under Ex Post Individual Rationality∗
This paper studies efficient partnership dissolution with ex post participation constraints in a setting with interdependent valuations. We derive a sufficient condition that ensures the existence of an efficient dissolution mechanism that satisfies Bayesian incentive compatibility, ex post budget balancedness, and ex post individual rationality. For equal-share partnerships, we show that our s...
متن کاملEx Post (In) Efficient Negotiation and Breakdown of Trade
Using a novel audit methodology, we show that reputation concerns and norms against price gouging can lead to breakdown in ex post efficient trade. Sellers in a market in India do not use their increased bargaining power to charge higher prices when customers have a shock, but, rather, forgo the order. However, when customers offer a higher price, sellers are significantly more likely to accept...
متن کاملEx-post efficient resource allocation for Self-organizing Cloud
Self-organizing Cloud (SoC) is a very scalable model, which aims to make full use of the geographically distributed computers to provide powerful aggregated computing ability. The resources are provisioned elastically according to user’s specific demand, by leveraging virtual machine (VM) resource isolation technology. The resource allocation atop SoC is very challenging in that it is not only ...
متن کاملEx-Post Constrained-Efficient Bilateral Trade with Risk-Averse Traders
We address robust mechanism design for bilateral trade of an indivisible commodity, under incomplete information on traders’ private reservation values. Under ex-post individual rationality and ex-post incentive compatibility, we define the notion of ex-post constrained-efficiency. It is weaker than interim constrained efficiency, and it is a notion of constrained optimality that is independent...
