Abstract This paper pro­poses a new method of inter­val estim­a­tion for the long run response (or elasti­city) para­meter from a gen­eral lin­ear dynamic model. We employ the bias-​​corrected boot­strap, in which small sample biases asso­ci­ated with the para­meter estim­at­ors are adjus­ted in two stages of the boot­strap. As a means of bias-​​correction, we use altern­at­ive ana­lytic and boot­strap meth­ods. To take atyp­ical prop­er­ties of the long run elasti­city estim­ator into account, the highest dens­ity region (HDR) method is adop­ted for the con­struc­tion of con­fid­ence inter­vals. From an extens­ive Monte Carlo exper­i­ment, we found that the HDR con­fid­ence inter­val based on indir­ect ana­lytic bias-​​correction per­forms bet­ter than other altern­at­ives, provid­ing tighter inter­vals with excel­lent cov­er­age prop­er­ties. Two case stud­ies (demand for oil and demand for beef) illus­trate the res­ults of the Monte Carlo exper­i­ment with respect to the super­ior per­form­ance of the con­fid­ence inter­val based on indir­ect ana­lytic bias-​​correction.
