Testing spatial interactions in Kaldor's growth laws: A cross‐country analysis

Abstract

This study tests spatial interactions in Kaldor's growth laws in a cross‐country perspective during 2000–2001 to 2014–2015. In particular, we examine the interactive hypothesis through spatial proximity using a spatial panel data framework. The results reveal that ordinary least square estimates undermine the relationship defined through standard Kaldorian setting, besides an inconsequential relationship in some cases. Spatial estimates support the Kaldorian growth strategy with a strong spatial interaction across the countries chosen. The first and third law show significantly positive spatial interactions in lag as well as error component. While as Verdon's law reflects similar as well as dissimilar spatial patterns in error and lag components respectively. The results reflect the fact that manufacturing labor productivity and output growth are more spatially interactive which is imperative for sustained higher economic growth. Therefore, highlighting the significant role of the manufacturing sector in attaining the higher steady state. The empirical findings suggest that the relationship between economic growth, manufacturing output, and labor productivity is global and spatially interactive. Considering these interactions may lead to narrowing down the disparities across the countries.
