Productivity, indexation and macroeconomic outcomes: The implications of goods market competition and wage bargaining structure

One strand of the macroeconomics literature explores the extent to which the indexation of nominal wages to a variable in addition to the price level can improve macroeconomic performance. The present paper contributes to this literature by developing a model in which the nominal wage is indexed not only to the price level but also to productivity. Two key features of the framework are a monopolistically competitive goods market and a unionized labor market in which wages are determined by a finite number of unions. A significant finding is that the multiparameter indexation scheme generally outperforms full-information wage setting.
