Public Goods Games (PGGs) are a standard experimental economic approach to studying cooperative behaviour. There are two types of games: discrete-time and continuous-time PGGs. While discrete-time PGGs (one-shot decisions about contributions to public goods) can be easily done as lab experiments, continuous-time PGGs (where participants can change contributions at any time) are much harder to realise within a lab environment. This is mainly because it is difficult to consider events happening in continuous time in lab experiments. Simulation offers an opportunity to support real-world lab experiments and is well suited to explore continuous-time PGGs. In this paper, we show how to apply our recently developed ABOOMS (Agent-Based Object-Oriented Modelling and Simulation) development framework to create models for simulation-supported continuous-time PGG studies. The ABOOMS framework utilizes Software Engineering techniques to support the development at the macro level (considering the overall study lifecycle) and at the micro level (considering individual steps related to simulation model development). Our case study shows that outputs from the simulation-supported continuous-time PGG generate dynamics that do not exist in discrete-time setting, highlighting the fact that it is important to study both, discrete and continuous-time PGGs.

ABOOMS：通过基于仿真的方法克服连续时间公共物品游戏的障碍

公共物品游戏（PGG）是研究合作行为的标准实验经济方法。游戏分为两种：离散时间PGG和连续时间PGG。虽然离散时间PGG（关于公益贡献的一次性决定）可以在实验室实验中轻松完成，但连续时间PGG（参与者可以随时更改贡献）在实验室环境中很难实现。这主要是因为在实验室实验中很难考虑连续时间内发生的事件。仿真提供了支持现实世界实验室实验的机会，非常适合探索连续时间的PGG。在本文中，我们展示了如何应用我们最近开发的ABOOMS（基于代理的面向对象的建模和仿真）开发框架来创建用于仿真支持的连续时间PGG研究的模型。ABOOMS框架利用软件工程技术来支持宏观（考虑整个研究生命周期）和微观（考虑与仿真模型开发相关的各个步骤）的开发。我们的案例研究表明，仿真支持的连续时间PGG的输出会生成离散时间设置中不存在的动力学，从而突出了以下事实：研究离散时间PGG和连续时间PGG都很重要。ABOOMS框架利用软件工程技术来支持宏观水平（考虑整个研究生命周期）和微观水平（考虑与仿真模型开发相关的各个步骤）的开发。我们的案例研究表明，仿真支持的连续时间PGG的输出会生成离散时间设置中不存在的动力学，从而突出了以下事实：研究离散时间PGG和连续时间PGG都很重要。ABOOMS框架利用软件工程技术来支持宏观水平（考虑整个研究生命周期）和微观水平（考虑与仿真模型开发相关的各个步骤）的开发。我们的案例研究表明，仿真支持的连续时间PGG的输出会生成离散时间设置中不存在的动力学，从而突出了以下事实：研究离散时间PGG和连续时间PGG都很重要。
