価格の硬直性の英語

従来は賃金の下方硬直性のため売上高が減少し売上原価率が上昇すると人件費率も上昇する傾向が見られたが、原油価格高騰が始まった2003年以降は、非正規雇用の増加に伴う雇用の流動化による賃金の硬直性の軟化を背景に、売上原価率が上昇するとそれを補うべく人件費率が低下するという関係が見られる36。例文帳に追加

Conventionally, when the sales decreased and sales cost ratio increased, the personnel cost ratio tended to increase with the downward rigidity of wages. However, since 2003, with the rise in the price of crude oil, a relationship has been apparent, in which the personnel cost ratio decreases to compensate for the increased sales cost ratio against the backdrop of the lower rigidity of wages due to the mobilization of employment that accompanies the increase in non-regular employment36. - 経済産業省
