We estimate an alternative type of monetary policy rule, termed Calvo rule, according to which the central bank is assumed to target a discounted in?nite sum of future expected in?ation. Compared to conventional in?ation forecast-based rules, which are typically of the Taylor-type with discrete...

The paper presents a closed economy model of endogenous growth driven by capital externalities arising from both private capital and public infrastructure. The model is calibrated to fit data for India, an approxmiately closed economy. Simulations suggest that fiscal policy certainly matters and...

We investigate the potential economic effects of spectrum trading amongst firms who require spectrum licences as part of their activities. Trading takes place within the technical interference constraints enforced by a regulator. The model accommodates a variety of markets and firms, as well as...

This survey reviews both theoretical and empirical papers that examine the economic effects of labour mobility with a particular reference to intra-European migration. We address three broad sets of issues: Firstly, the effect that immigration has on the host country's labour market. Although...

A new perspective is provided on a puzzle that has emerged from the empirical lit- erature suggesting that government-independent central banks provide a `free lunch': lower in°ation is apparently achieved at no cost in terms of greater output variance. We assess the various explanations...

The Harris-Todaro model of rural to urban migration is extended to include urban agglomeration effects, some urban real wage flexibility and a government budget constraint. Without employment subsidies, laissez-faire migration is excessive unless real wage flexibility and agglomeration effects...

This paper provides a first attempt to quantify and at the same time utilize estimated measures of uncertainty for the design of robust interest rate rules. We estimate several variants of a linearized form of a New Keynesian model using quarterly US data. Both our theoretical and numerical...

Treating spectrum of different bandwidths as essentially distinct inputs needed for possibly different types of services has formed the core of spectrum analysis in academic research so far. New technological advances, such as cognitive radio, now allow us to move away from this inflexibility...

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,...

The question of why the unemployment rate takes a long time before it reverts back to its natural-rate following a negative exogenous shock has been the subject of unremitting interest in macroeconomics. This paper shows that the speed of adjustment to the steady-state unemployment and the...
