This paper examines the effect of the announcement of various types of
airline wage concessions on stock market value. Our results show that
capital markets respond positively to wage cuts but not significantly
to wage freezes or two-tier settlements. However, a significant intra
industry spillover effect from two-tier agreements was found that sugg
ests that concessions by one carrier decreases the value of the remain
ing carriers. The results also vary by craft, indicating that labor ma
rket and institutional characteristics influence market response.
