Our estimations control for age (in years) and age squared, tenure at current job (in years) and tenure squared, education (in years), a sex dummy, an urban location dummy, household size, dummies for having a kitchen and water source outside of the dwelling, and initial labor supply.
Interactions of gender with age, its square, job tenure, civil status, and children are also included.
Interactions of female with age, its square, job tenure, married, and parent are also included.
If it is merely office space, then he may not even equal Giuliani, during whose tenure millions of square feet of commercial space have gone up in Times Square alone.
The PL equation includes individual-, firm-, and industry-specific control variables: (i) B it is a set of worker including an age categories, marital status, job tenure and tenure squared, region of residence, union membership, and earnings in period year t−1; (ii) I j is industry-specific dummy variables; and (iii) D t is a set of year-specific dummy variables.
The covariate vector x it consists of variables such as age, dummy variables for being foreign, having completed an apprenticeship, obtained a university degree, working part-time, having a temporary contract, and being a white-collar employee, as well as tenure and tenure squared.
Worker controls comprise potential experience and tenure (both linearly and squared), dummy variables for joining the plant before 1975 (i.e. censored job tenure), five levels of education, non-German nationality, year of observation, and three-digit occupation.
Similarly, the chi-square result (X2 = 8.792) of land tenure security was found to be statistically significant at the 95% level of significance.
We include worker's schooling years, Y ij ; potential experience, PE ij (level and squared), defined as the difference between employee's age and the expected age to complete his studies according to their official length; and tenure T ij (level and squared), defined as the number of years working for the current employer.
During his 20-year tenure, he has overseen the addition of 80 million square feet of development, increasing the city's total square footage of office and residential space by 11 percent.
Further Controls: Small Firm, Female, Age, Age Squared, Years of Education, Married, Children age ≤5, Tenure, Year dummies.
