2017年6月9日上午，加拿大圭尔夫大学（University of Guelph） Thanasis Stengos教授做了题为“Persistence and Convergence in Economic Growth and Club Formation”的学术报告。
    作者在允许结构断点的长记忆框架下，提出了国别经济收敛的四个假设，从单元变量和多元变量的角度来估计长记忆的参数值。运用国别人均GDP差额，作者确认了以往文献中所认为的长记忆模式的存在性，但作者的单元变量分析表明对此论点的论据支持较弱。他提出团组整合的概念，并运用序贯检验准则进行检验。最后，提出了在度量金融一体化方面的新应用。
