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...

This paper explores the similarity of the underlying economic problems that lead to the establishment of (a) independent central banks to operate national monetary policies and (b) independent regulatory agencies for telecommunications and other utility service industries. We show that, in both...

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 contribute to a recent literature on the normalization, calibration and estimation of CES production functions. The problem arises because CES 'share' parameters are not in fact shares, but depend on underlying dimensions - they are 'dimensional constants' in other words. It follows that such...

We analyse the effects of a government spending expansion in a dynamic stochastic general equilibrium (DSGE) model with Mortensen-Pissarides labour market frictions, deep habits and a constant-elasticity-of-substitution (CES) production function. The combination of deep habits and CES technology...

Dynamic principal-agent settings with asymmetric information but no commitment are well known to create a ratchet effect. Here, the most efficient agents must be provided with extra 'information rent' as an incentive to relinquish their informational advantage over an uninformed principal; this...

How does informality in emerging economies affect the conduct of monetary policy? To answer this question we construct a two-sector, formal-informal new Keynesian closed-economy. The informal sector is more labour intensive, is untaxed, has a classical labour market, faces high credit...

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...

A New-Keynesian model with deep habits and optimal monetary policy delivers a fiscal multiplier above one and the crowding-in effect on private consumption obtainable in a Real Business Cycle model à la Ravn et al. (2006). Optimized Taylor-type or price-level interest rate rules yield...
