B5: Table 1 below reports OLS estimates for two spectator demand models using data from the League of Ireland. The dependent variable is log attendance. The first column contains estimates for the Premier Division (Tier 1) and the second contains estimates for the First Division (Tier 2). The season is played from early March to the end of October. The variable reported in this table is 'sunset time', which is the time at which the sun sets on the evening of the match expressed using the 24-hour clock (e.g., 21.30 is 9:30 pm). A number of other explanatory variables are also included in the regression models but their estimates are not reported in the table below to conserve space. What concept does 'sunset time' represent in these spectator demand models? Do the estimated signs reported for this variable make sense? Compare the estimates for 'sunset time' between the Premier Division (Tier 1) and the First Division (Tier 2). What might you conclude from the difference between these two estimates?
