This paper provides empirical evidence on investors' perceptions of th
e relative advantages and costs of spatial agglomeration. Specifically
, we examine the stock price effects of headquarters relocations. The
stock market reaction is significantly positive when relocation decisi
ons are attributed to cost savings, indicating that cost savings avail
able at less centralized locations outweigh any loss of enhancements a
ssociated with spatial clustering at urban centers. In contrast, decis
ions prompted by managerial self-interest and desire for luxurious off
ices elicit an adverse reaction from investors. (C) 1995 Academic Pres
