Policymakers decide on alternative policies facing restricted budgets and uncertain, ever-changing future. Designing housing policies is further difficult giving the heterogeneous characteristics of properties themselves and the intricacy of housing markets and the spatial context of cities. We propose PolicySpace2 (PS2) as an adapted and extended version of the open source PolicySpace agent-based model. PS2 is a computer simulation that relies on empirically detailed spatial data to model real estate, along with labor, credit and goods and services markets. Interaction among workers, firms, a bank, households and municipalities follow the literature benchmarks to integrate economic, spatial and transport literature. PS2 is applied to a comparison among three competing municipal housing policies aimed at alleviating poverty: (a) property acquisition and distribution, (b) rental vouchers and (c) monetary aid. Within the model context, the monetary aid, that is, a smaller amounts of help for a larger number of households, makes the economy perform better in terms of production, consumption, reduction of inequality and maintenance of financial duties. PS2 as such is also a framework that may be further adapted to a number of related research questions.

PolicySpace2：为市场和内生住房政策建模

政策制定者决定面对预算有限和不确定，不断变化的未来的替代政策。考虑到房地产本身的异质性，住房市场的复杂性以及城市的空间背景，设计住房政策将更加困难。我们建议PolicySpace2（PS2）作为基于开源PolicySpace代理的模型的改进和扩展版本。PS2是一种计算机模拟，依靠经验丰富的空间数据来对房地产，劳动力，信贷以及商品和服务市场进行建模。工人，企业，银行，家庭和市政当局之间的互动遵循文献基准，以整合经济，空间和运输文献。PS2用于比较旨在减轻贫困的三项相互竞争的市政住房政策：（a）购置和分配财产；（b）租金凭单；以及（c）货币援助。在模型的背景下，货币援助，即为大量家庭提供的少量援助，使经济在生产，消费，减少不平等和维持金融义务方面表现更好。这样的PS2还是可以进一步适应许多相关研究问题的框架。
