1.If the function form of g is g=yi and the function form of fis f=,then the estimated coefficient of means that an increase in pi by 1% leads to a fall in by 0.453% ( fall because the sign is negative and thus pi and yi are inversely related)
2.If the function form of g is g=yi and the function form of f=in,then the estimated coefficient of means that an increase in pi by 1% the different in the expected mean of falls by 0.453 (fall because the sing is negative and thus Pi and Yi are inversely related)
