Is there Causal Relationship between Money Supply Growth and Inflation in China? Evidence from Quantity Theory of Money

This study examines the causal relationship between Chinese money supply growth and inflation, using the bootstrap Granger full‐sample causality test and sub‐sample rolling‐window estimation test to determine whether such a relationship in China supports the quantity theory of money. The result indicates that there is a unidirectional relationship from inflation to money supply growth. However, considering structural changes in two series, we find that short‐run relationships using full‐sample data are unstable, which suggests that full‐sample causality tests cannot be relied upon. Then, we use a time‐varying rolling‐window approach to revisit the dynamic causal relationship, and the results show that money supply growth has both positive and negative impacts on inflation in several sub‐periods, and in turn, inflation has the same effects on money supply growth for China. These findings are basically consistent with the modern quantity theory of money from the perspective of money supply and price level. When money supply growth does not outweigh output growth, inflation should not be curbed only by decreasing money supply. It notes that a stable money supply growth is critical to price level stability and economic development in China.

Does the cessation of quarterly earnings guidance reduce investors’ short-termism?

The practice of providing quarterly earnings guidance has been criticized for encouraging investors to fixate on short-term earnings and encouraging managerial myopia. Using data from the post–Regulation Fair Disclosure period, we examine whether the cessation of quarterly earnings guidance reduces short-termism among investors. We show that, after guidance cessation, investors in firms that stop quarterly guidance are composed of a larger (smaller) proportion of long-term (short-term) institutions, put more (less) weight on long-term (short-term) earnings in firm valuation, become more (less) sensitive to analysts’ long-term (short-term) earning forecast revisions, and are less likely to dismiss chief executive officers for missing quarterly earnings targets by small amounts, relative to investors in firms that continue to issue quarterly earnings guidance. Our study provides new evidence of the benefit of stopping quarterly earnings guidance, that is, the reduction of short-termism among investors.

农地流转多重主体博弈分析—兼论农户权益保障

土地流转是实现农业规模化、集约化发展的必经之路.农地流转是多重主体利益博弈的结果.在转入方、转出方、中介机构和政府的多方博弈中,农户处于弱势地位,其土地权益难以保障.应构建合理的农户权益保障机制,约束企业、政府不合理的利益扩张行为,使土地流转博弈框架回归“帕累托优化”均衡.
