    Symposium on exchange rate policy and competitiveness
    (University College Dublin. School of Economics, 1982-11) ; ; ;
    The four papers in this symposium were originally presented at the Fifth Annual Economic Policy Conference of the Dublin Economics Workshop held in Killarney on October 15-17 1982 and are published together in this Policy Paper with only minor alterations. Taken together, they illustrate the complexity of the issues which must be faced in devising an exchange-rate policy as well as the diversity of views held by economists on the subject.

    Endogenous mode of competition in general equilibrium
    (University College Dublin. School of Economics, 2005-12-12) ;
    This paper endogenises the extent of intra-sectoral competition in a multi-sectoral model of oligopoly in general equilibrium. Firms choose capacity followed by prices. If the benefits of capacity investment in a given sector are below a threshold level, the sector exhibits Bertrand behaviour,otherwise it exhibits Cournot behaviour. By endogenising the threshold parameter in general equilibrium, we show how exogenous shocks alter the mix of sectors between "more" and "less" competitive, or Bertrand and Cournot. The model also has implications for the effects of trade liberalisation and technological change on the relative wages of skilled and unskilled workers.

    International trade and the environment : theoretical and policy linkages
    (University College Dublin. School of Economics, 2005-06-23)
    I review and extend three approaches to trade and environmental policies: competitive general equilibrium, oligopoly and monopolistic competition. The first two have surprisingly similar implications; deviation deviations from first best rules are justified only by constraints on policy choice (which motivates what I call a "single dividend" approach to environmental policy), and taxes and emissions standards differ in ways which reflect the Le Chatelier principle. I also show how environmental taxes may lead to a catastrophic relocation of industry in the presence of agglomeration effects, although not necessarily if there is a continuum of industries which differ in pollution intensity. An earlier version was presented as an invited plenary lecture to the European Association for Environmental and Resource Economics Conference, Oslo, 1999.

    Cross-border mergers as instruments of comparative advantage
    (University College Dublin. School of Economics, 2004-03-01)
    A two-country model of oligopoly in general equilibrium is used to show how changes in market structure accompany the process of trade and capital market liberalisation. The model predicts that bilateral mergers in which low-cost firms buy out higher-cost foreign rivals are profitable under Cournot competition. With symmetric countries, welfare may rise or fall, though the distribution of income always shifts towards profits. The model implies that trade liberalisation can trigger international merger waves, in the process encouraging countries to specialise and trade more in accordance with comparative advantage.

    Comparing the wealth of nations : reference prices and multilateral real income indexes
    (University College Dublin. School of Economics, 1997-06-24) ;
    This paper considers the problem of comparing real incomes across countries. The available methods are reviewed and their performance is compared using the raw data underlying the Penn World Table. The results throw light on the relative merits of different indexes and on the empirical importance of the "Gerschenkron effect": the downward bias in a country's measured real income when its own prices are used as weights. They also demonstrate the feasibility of using empirical demand parameters to estimate the GAIA ("Geary-Allen International Accounts") System.
