To circumvent the potential endogeneity problem associated with the task content of an occupation, we use as instrument the residuals from a task-wage regression model (TASK kt = constant + hrlWage kt + error term2SRI).
The task content determines how skilled a worker must be to qualify for work in a particular occupation.
A more comprehensive theoretical framework of time management than presented so far would have to involve task content and social influences as well.
Section 5 investigates the task content of occupations.
This allows for examination of the association between employment changes and the task content of occupations.
To assure task content consistency, a topic familiarity questionnaire was used.
Three important criteria were used for selection of the tasks; tasks appropriateness, task complexity and task content consistency.
Therefore, I perform a shift-share analysis to evaluate the evolution of the tasks' content, exploring whether the changes of the task content of occupation are due to changes within occupations (intensive margin) or between occupations (extensive margin).
We draw on information related to the task content of an occupation for a second instrument into the wage equation.
Thus, differences in task type and task content may be confounding factors that were not controlled for when measuring the mode effects.
