1 Erratum to: Eurasian Bus Rev DOI 10.1007/s40821-016-0065-1

Due to a technical mistake in Table 3 the asterisks were placed after the second value (standard errors) instead of after the first value (coefficient). In addition there should have been parentheses around the second values (standard errors) in lines.

The publisher apologizes for this mistake. The original article was corrected.
