具有外生价格的整数商品交换
Bartering integer commodities with exogenous prices
摘要：
对具有不可分割商品和固定外生价格的市场的分析在经济模型中发挥了重要作用，特别是在工资刚性和失业方面。本研究报告提供了与Nasini等人提出的基于数学规划的方法相关的数学和计算细节。（2014年接受）研究纯交换经济，其中离散量的商品以固定价格交换。易货过程，由一对夫妇的代理之间的商品的基本重新分配序列，形式化为局部搜索收敛到均衡分配。在计算经济学的背景下，提供了一个直接应用程序的分析过程，随着Java实现本研究报告中描述的方法。
英文摘要：
The analysis of markets with indivisible goods and fixed exogenous prices has played an important role in economic models, especially in relation to wage rigidity and unemployment. This research report provides a mathematical and computational details associated to the mathematical programming based approaches proposed by Nasini et al. (accepted 2014) to study pure exchange economies where discrete amounts of commodities are exchanged at fixed prices. Barter processes, consisting in sequences of elementary reallocations of couple of commodities among couples of agents, are formalized as local searches converging to equilibrium allocations. A direct application of the analyzed processes in the context of computational economics is provided, along with a Java implementation of the approaches described in this research report.
