We investigate the effects of individual top managers on wages and wage policies. A large longitudinal administrative dataset from Portugal allows us to match workers,firms and top managers, and follow the movements of the latter across different firms over time. We estimate the role of top...

This paper develops a two-country, general equilibrium model of oligopoly in which the degree of horizontal product differentiation is endogenously determined by firms' strategic investments in product innovation. Consumers seek variety and product innovation is more skill intensive than...

We investigate the impact of exchange rate movements on wage determination in unionised labour markets. Using a simple model of international oligopoly, we show that organised labour has a rational incentive to accept lower wages in the face of a currency appreciation. This proposition is...

In an international duopoly model, we investigate how trade liberalisation impacts on collective bargaining outcomes when workers are represented by open shop unions. We find that, with intermediate levels of union density, trade liberalisation may lead to higher negotiated wages even if no...

We develop a two-country, multi-sector model of oligopoly in which unionised and non-unionised sectors interact in general equilibrium. The model is used to study the impact of trade liberalisation, deunionisation and firm entry on wages in unionised and non-unionised sectors, and on welfare. We...

Evidence on the effect of product market competition on unionized wages is mixed. In this paper we show theoretically that the result may reflect genuine heterogeneity in the response of union wages to product market conditions. For low levels of unionization, union bargaining power may actually...

In an international oligopoly model, we investigate how trade liberalisation impacts on collective bargaining outcomes when workers are represented by open shop unions. We find that, with intermediate levels of union density, trade liberalisation may lead to higher negotiated wages even if no...

We examine corporate restructuring following privatization using uncommonly rich data on the population of Portuguese …firms from 1991-2009. We …find that privatization leads to sizable job losses, reflecting reductions in both the number of establishments and in the number of workers per...
