| Summary: | The incorrect fxed-effect assumption, missing-data problem, omitted-variable problem,
and errors-in-variables (EIV) problem are estimation problems that are generally found
in studies on weather effects on asset returns. This study proposes an approach that can
address these problems simultaneously. The approach is demonstrated by revisiting the
effects on the Stock Exchange of Thailand. The sample shows daily data from 2 January
1991 to 30 December 2015. Artifcial Hausman instrumental-variable regressions
successfully improve the quality of the analyses for ordinary least squares regressions when
signifcant EIV problems are identifed and the regression results in a conflict. The study
fnds signifcant air pressure and rainfall effects and empirically shows that the temperature
effects reported by previous studies were induced by the fxed-effect assumption and are
therefore incorrect. |
