We study how unionization affects competitive selection between heterogeneous firms when wage negotiations can occur at the firm or at the profit-centre level. With productivity specific wages, an increase in union power has: (i) a selection-softening; (ii) a counter-competitive; (iii) a...

This paper first presents stylized evidence showing how the date of the adoption of competition policy is correlated with country size. Smaller countries tend to adopt competition policy later. We then present a theoretical model with countries of different size, trade costs, and firms competing...

This paper implements a fair wage constraint into an analytically tractable core-periphery agglomeration model. This enables us to study the role of imperfect labour markets for the pattern of agglomeration. In the short run, a marginal increase in fair wage preferences leads to an unambiguous...

We investigate the spatial distribution and organization of an imperfectly competitive industry when firms may choose to operate more than a single production unit. Focusing on a short-run setting with a fixed mass of firms, we first fully characterize the spatial equilibria analytically....

This study develops a model of trade that highlights the effects of the interconnection of country-specific communications networks as a driving force behind trade in high-tech products with positive transport costs. By constructing a two-country model of monopolistic competition with two...

We build a two-country model of monopolistic competition with communications networks. A communications network is characterized by (1) the existence of large fixed costs of network provision, and (2) the presence of congestion. It is demonstrated that both the size of a country and the relative...

Large distance and border effects on trade flows in some industries may result from the collusive division of geographic markets. In the Brazilian cement industry, traditional gravity equations fit the data well, yet limited regional flows are due to firms' strategic behaviour. Thanks to a...

In this study a multi-country model of trade is developed that captures the role of country-specific communications network interconnectivity, which enhances trade in intermediate business services. The number of countries connected to internationally interconnected networks is found to...

Communicable diseases pose a formidable challenge for public policy. Using numerical simulations, we show under which scenarios a monopolist's price and prevalence paths converge to a non-zero steady state. In contrast, a planner typically eradicates the disease. If eradication is impossible,...

This paper investigates the signalling role of tax policy in promoting, or hindering, the ability of a monopolist to practise entry deterrence. We show that environmental policy can facilitate the incumbent firm's concealment of information from potential entrants, thus deterring entry, and yet...
