Bayesian estimation is employed to investigate whether deep as opposed to superficial habit improves the fit of a dynamic stochastic general equilibrium model. If the stock of superficial habit features the additional persistence typical of deep habit, the two specifications are virtually as...

This paper contributes to an emerging literature that brings the constant elasticity of substitution (CES) specification of the production function into the analysis of business cycle fluctuations. Using US data, we estimate by Bayesian methods a medium-sized DSGE model with a CES rather than...

We present a model of transnational terrorism where two countries, home and foreign, face a terrorist threat based in the foreign country. The home country chooses how much to invest in defending itself or in reducing terrorist resources either indirectly by subsidising the foreign country or by...

We study relative preferences in a general equilibrium model where households make social comparisons and/or get habituated to levels of labour-effort they supply and goods they consume. Bayesian estimations for the US support the existence of a society based on such preferences. In particular,...

We develop an endogenous growth model driven by externalities of both private capital and public infrastructure. The government levies distortionary taxation to finance a publicly provided consumption good and public infrastructure. Firms face adjustment costs. We first study the steady state,...

This paper examines the implications of imperfect information (II) for optimal monetary policy with a consistent set of informational assumptions for the modeller and the private sector an assumption we term the informational consistency. We use an estimated simple NK model from Levine et al....

We revisit the influential work of Borjas (1995) on the economic gain to the host population from immigration-"the immigration surplus." We develop his analysis by using a general equilibrium endogenous growth model with endogenous capital and several sectors, including an R&D sector driving...

The UK, with its relatively liberal immigration policies following recent enlargements, has been one of the main recipients of migrants from new EU member states. This paper poses the questions: what is the effect of immigration on a receiving economy such as the UK? Is the effect beneficial or...
