英文文献摘要:
Imposing curvature and monotonocity restrictions always has been a vexing problem for applied economists. We present an estimation methodology for more efficiently estimating flexible functional forms subject to "regional", as opposed to "local" or "global", regularity conditions. The technique involves a Markov Chain Monte Carlo sampler to ensure consistency over a predefined connected set of the regressor space. Numerical examples demonstrate the advantages and technical feasibility of our new approach.
施加曲率和单调速度限制一直是应用经济学家头疼的问题。我们提出了一种评估方法,以更有效地评估受“区域”约束的灵活函数形式,而不是“局部”或“全局”的正则性条件。该技术涉及马尔可夫链蒙特卡洛采样器,以确保在预定义的回归空间连通集上的一致性。数值算例表明了新方法的优越性和技术可行性。
