Crying after birth can lead to a temporary increase in intra-thoracic pressure due to the forceful contraction of respiratory muscles and closure of the glottis during the act of crying. This can create a momentary negative pressure in the thoracic cavity as the infant inhales deeply. However, the overall impact of crying on intra-thoracic pressure is complex and varies with the infant's respiratory patterns. Generally, while crying may influence pressure dynamics, it is not the primary focus of concern in newborns immediately after birth.

What causes the labor supply curve to shift?
Changes in market wages cause a movement along the labour supply curve, adjusting employment levels for certain wages; whereas shifts of the curve will change employment levels at any given wages. Shifts are caused by: changes inthe demongraphic: which can affect supply of labour of certain age groups, the low bitrth rate of the 70s has decreased tge supply of young labour in the 90s, atany given wage. sectoral changes: the service industry and low-pay sectors employ increasingly high proportions of young people. The increasing emphais on skill attainment means that young people are unlikly to be demand in high-level jobs, who offer them uncompetitive wages, hence more will be attracted tothe sector where the respective demand is higher. Sectoral shifts can shift supply curve.
