In Ulph (2002) I analysed how the possibility of future resolution of uncertainty about damage costs affected the incentives and timing for countries to join a self-enforcing international environmental agreement (IEA). I analysed two membership rules – fixed (countries commit whether to...

Much of the literature on international environmental agreements uses static models, although most important transboundary pollution problems involve stock pollutants. The few papers that study IEAs using models of stock pollutants do not allow for the possibility that membership of the IEA may...

I analyse how the possibility of future resolution of uncertainty about damage costs affects incentives to join a self-enforcing international environmental agreement. Unlike earlier literature, the model allows many countries, uses a solution concept which does not restrict the size of a stable...

This paper investigates the effects of unobservable factors that, as is well-known, contaminate two of the variables most used in labour market research, namely the stock of unemployment and the stock of vacancies. Using a matching function framework, we compare different panel data estimators...

For the widely-used linear-quadratic model of stable IEAs the key results are: (i) if the members of the IEA act in a Cournot fashion with respect to non-signatories, a stable IEA has no more than 2 signatories; (ii) if the signatories act as Stackelberg leaders, a stable IEA can have any number...

In-work benefits are becoming an increasingly relevant labour market policy, gradually expanding in scope and geographical coverage. This paper investigates the equilibrium impact of in-work benefits and contrasts it with the traditional partial equilibrium analysis. We find under which...

This paper examines the profitability of horizontal merger in an open economy with Cournot competition. We find that duopoly is a necessary, but not sufficient, condition for domestic merger to be profitable. A cross-border merger, however, can be profitable from any market structure. <br><br> Keywords;...

We develop a novel computerized real effort task, based on moving sliders across a screen, to test experimentally whether agents are disappointment averse when they compete in a real effort sequential-move tournament. Our theory predicts that a disappointment averse agent, who is loss averse...

Does innovation boost or fall with more competition when innovation follows a memory process? This paper provides a theoretical model which analyzes the innovation and competition relationship assuming that innovation follows a short-memory process. I find innovation increases with more product...

The relationships between real wages, output per capita, inflation and unemployment in Italy between 1970 and 1994, are modelled using a cointegrated vector autoregression. There is evidence of a change in the underlying equilibria and in the dynamic evolution of the variables, probably...
