6. The maximum average wage that an industry is willing to pay depends on industry profitability, itself depending on labour productivity capital productivity and the ability of the industry to impose prices higher than competitive prices where (w k ) is the maximum nominal wage industry (k) is willing to pay ( π k ) is labour productivity ( π k / κ k ) is capital productivity (p k ) and (p cap ) are value added and fixed capital prices (R) is average profitability across industries The average industry wage depends on industry profitability… Inter-industry wage differentials Occupational wage differentials Gender pay gap Public / private sector wages Wages an industry is willing to payBalance of bargaining powerExtra Profits The average wage Minimum vs average wage

7. The maximum average wage that industry (k) is willing to pay is not what is actually paid (w k ) When bargaining at the industry (k) level, workers target the maximum average wage that industry (k) is willing to pay, if there are extra-profits in this industry (); otherwise they target the “necessary wage”, which acts as a wage floor. They obtain then a wage that depends on their target one hand and on their bargaining power on the other. where (W k ) is nominal wage actually paid in industry (k) (w k ) is the maximum nominal wage industry (k) is willing to pay ( λ k ) is an index of the balance of power between workers and employers … and on the bargaining power of workers Inter-industry wage differentials Occupational wage differentials Gender pay gap Public / private sector wages Wages an industry is willing to payBalance of bargaining powerExtra Profits The average wage Minimum vs average wage

10. Differences in occupational wages within industries are independent of industry-specific characteristics. Occupational wages vary around the average industry wage depending on the characteristics of occupation (j) in industry (k). Characteristics of occupations: years of schooling, age (professional experience) and tenure in (j,k). Job variables: shift work, overtime and other variables leading to compensating differentials in (j,k). The quality of the workforce explains occupational wage differentials Inter-industry wage differentials Occupational wage differentials Gender pay gap Public / private sector wages The average wage Minimum vs average wage next

17. Public / private sector wages Inter-industry wage differentials Occupational wage differentials Gender pay gap Public / private sector wages In Greece, the average wage is higher in the public sector than in the private sector for both genders The difference in wages between sectors is mainly attributed to the employee’s endowment. However, in the lowest quantile a significant part of the wage difference between sectors (almost 50%) is due to the advantage of public sector and the disadvantage of the private sector. In the highest quantile the wage difference is mainly attributed to the employee’s characteristics The pattern of this finding is similar for male and female employees. These findings may explain the behaviour of the less-skilled male and female employees who prefer to be employed in the public sector at the early stages of their career than accept the relatively low-paying jobs in the private sector. On the other hand, the advantage of the private sector in the upper range of the wage distributions may explain the flight of senior managers from the public to the private sector Papapetrou E (2006) The average wage Minimum vs average wage
