We estimate the relationship between pensions and wages controlling for variations in the size of the compensating differential related to firm size or the presence of a union. Both firm size and unionism are commonly associated with the payment of wage premia and/or the presence of market power where the costs of fringe benefits to the firm may be less. Our results are consistent with these a priori expectations and suggest that the magnitude of the compensating differential is significantly higher in nonunion and in small firms. ER -
