Are costs really sticky and biased? Evidence from manufacturing listed companies in China

Abstract

ABSTRACTRecent studies on cost behaviour have proved that cost increase caused by business expansion is larger than cost decrease caused by business downsizing. This cost stickiness behaviour contradicts the traditional theoretic assumption that cost level and business size change in a linear way. This article investigates the existence or non-existence of cost stickiness using a sample of China’s manufacturing listed companies during the period 2010–2014. First, our findings show that cost stickiness is a pervasive phenomenon and overestimated in the manufacturing industry. Second, we find that cost stickiness varies greatly across industries and in different regions. Finally, we find that cost stickiness is affected by the economic growth. Specifically, cost stickiness increases with the macroeconomic growth. Our results from China’s manufacturing listed companies provide evidence on asymmetric cost behaviour and contain important implications for both cost accounting research and financial accounting research.
