Income inequality was not associated with mortality after controlling for state-level sociodemographic covariates.
The estimate is robust across models, also when controlling for state fixed effect, education, and marital and employment status.
Controlling for state or governor fixed effects as well as year fixed effects does not resuscitate the difference in allowance rates (Table 9).
Using a panel of states, I estimate the effect of within-state changes in the minimum wage on state immigrant counts, taking into account key economic indicators in the calculation of expected earnings and controlling for state and national trends.
Even after controlling for state-fixed effects and nation-wide entry year effects, a potential source of bias remains if the timing and location of labor market entry are endogenous and affected by business cycle conditions.
The patterns in the figure underscore the importance of controlling for state-specific time trends: there was a gradual rise in GPA over time that began before the implementation of the preference ban. Figure 1 College Board outcome variables.
The size of this effect increased when controlling for state's per capita R&D expenditure and for study characteristics that previous research showed to correlate with the frequency of positive results, including discipline and methodology.
At the level of policies, states' school policies affecting food services and nutrition are significantly associated with prevalence of obesity among youth even after controlling for state-level measures of ethnicity and income (35).
It was hypothesized that both a low performance and amount of perseverations made on the letter fluency task should, when controlling for state anxiety during baseline, predict an increased level of state anxiety during the hand-grenade throwing exercise.
Table 5 displays the adjusted model controlling for state regional grouping (six regions), metropolitan area population size, county-level voter turnout, tract-level poverty, tract-level material deprivation score (Townsend index), and tract-level population density.
