Assuming constant marginal cost, it is shown that a switch from specific to ad valorem taxation has no effect on the critical discount factor required to sustain collusion. This result is shown to hold for Cournot oligopoly as well as for Bertrand oligopoly when collusion is sustained with...

We consider the well-analyzed abatement game (Barrett 1994) and prove that correlation among the players (nations) can strictly improve upon the Nash equilibrium payoffs. As these games are potential games, correlated equilibrium - CE - (Aumann 1974, 1987) cannot improve upon Nash; however we...

In this paper, we explore the recent gender wage gap trends in a sample of European countries with a new approach that uses the direct measures of skill requirements of jobs held by men and women. We find that, during the 1990s and 2000s, the gender wage gap declined in the majority of the...

In this short article we explain how to test an economic model using Indirect Inference. We then go on to show how you can use this test to estimate the model.

This paper analyses issues related to weak exogeneity in a financial point process. We extend the Hausman test of weak exogeneity in a time series model and propose three cases in which weak exogeneity conditions will break down. The simulation study suggested that a failure of the exogeneity...

We add the Bernanke-Gertler-Gilchrist model to a world model consisting of the US, the Eurozone and the Rest of the World in order to explore the causes of the banking crisis. We test the model against linear-detrended data and reestimate it by indirect inference; the resulting model passes the...

We propose a numerical method, based on indirect inference, for checking the identification of a DSGE model. Monte Carlo samples are generated from the model's true structural parameters and a VAR approximation to the reduced form estimated for each sample. We then search for a different set of...

We show that the static duopoly model in which firms choose between exporting and foreign direct investment is often a prisoners' dilemma game in which a switch from exporting to foreign direct investment reduces profits. By contrast, we show that when the game is repeated there is a range of...

Organised crime is unique within the underground economy. Unlike individual criminals, criminal organisations can substitute between a variety of inputs; chiefly labour and effort. This paper considers the effect of several popular anti-crime policies in such an environment. Using a profit...

We propose a general form of vector Multiplicative Error Model (MEM) for the dynamics of duration, volume and price volatility. The vector MEM relaxes the two restrictions often imposed by previous empirical work in market microstructure research, by allowing interdependence among the variables...
