Union-Firm Bargaining and the Influence of Product Market Power and Production Technology on Systematic Risk

Abstract
The relationship between the CAPM firm beta and the firm's microeconomic decisions is studied by a model under uncertainty, which combines the feature of an ex ante “inputs substituable” production technology and the existence of a union which bargains over various economic dimensions of the firm. It is shown that the earlier findings of a relationship between the firm beta, the firm product market power, and the labor-capital ratio may be reinforced through the indirect channel of labor market bargaining, but the relationship becomes more complex, and heavily depends on the scope of the union-firm bargaining process. This yields the empirical prediction, confirmed for a panel of Belgian firms, that any proper estimation of the determinants of firm beta, must control for firms in the sample being unionized.
