In the above article, the initial version of “A Question of Costliness: Time

Horizons and Interstate Signaling” (Haynes 2019) published Online First contained

an error in defining an important cutpoint. This error is corrected below, along with

an updated figure. The Online First manuscript also presented three inequalities that

incompletely defined the parameter spaces delimiting certain equilibria. These

inequalities are presented in a more complete way here. These errors and omissions

do not affect the paper’s results.

1) Due to a simple mathematical error, Equation (1) was initially misspe-

cified, including an extra term in the denominator. Equation (1) s hould

read:

pS1

H1þS1

2) As a result of the correction to Equation (1), Figure 1 should depict two

distinct cutpoints along the horizontal axis.

The corrected version of Figure 1 still reflects the theoretically important

insight, that mutual cooperation across both rounds of the game is only

possible under unidimensional uncertainty when p1>p:

3) Inequalities (2), (4) , and (6) in the original manuscr ipt were incomplete.

Because the surrounding narrative focused on P1’s first round incentives,

the Online First version of the manuscript only reported the cutpoints defin-

ing P1’s first round strategy. Fuller expressions of the conditions defining

these equilibria are given below.

Inequality (2) should read:

p11H1E1

q1ðH1þS1E1Þ;S1ð1q1Þ

H1þS1ð1q1Þ
