Interpretation dummy variable

[gobbble]

Hello together, I have a question regarding the interpretation of a dummy variable.

I run three regressions, all with the same return index as dependent variabel.

each regression had 2 regressors: GDP growth and change in USD/exchange rate of one specific country each.

In addition, for each regression a crisis dummy is included with identical specifications.

RESULT:

In all regressions, the dummy variable is significant, but in two cases the coefficient is positive and in one case it is negative.

Does it make sense? How do I interprete the results? The OLS regression is blue.

Thanks!
