How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

How do oil price fluctuations affect economic activity and policy in the context of oil-exporting emerging economies? Past research suggests that the output responses to oil price innovations are asymmetric in nature but does not directly test the asymmetry in the government expenditure adjustments triggered by the shock. Moreover, many studies qua...
We develop an open economy DSGE model of the Indian economy and estimate it by Bayesian Maximum Likelihood methods. We build up in stages to a model with a number of features important for emerging economies in general and the Indian economy in particular: a large proportion of credit-constrained consumers, a financial accelerator facing domestic f...
We contribute 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-Maximum-Likelihood methods a standard medium-sized DSGE model with a CES rather than Cobb-Douglas (CD) technology. We esti...
We develop a closed-economy DSGE model of the Indian economy and estimate it by Bayesian Maximum Likelihood methods using Dynare. We build up in stages to a model with a number of features important for emerging economies in general and the Indian economy in particular: a large proportion of credit-constrained consumers, a financial accelerator fac...
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 results close to optimal policy and dominate a conventional Ta...
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 constraints in financing investment and is less visible in terms...
How does informality in emerging economies affect the conduct of monetary and fiscal 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 constraints in financing investment and is less visib...
We provide a tool for estimating DSGE models by Bayesian Maximum-likelihood meth?ods under very general information assumptions. This framework is applied to a New Keynesian model where we compare the standard approach, that assumes an informa?tional asymmetry between private agents and the econometrician, with an assumption of informational symmet...
Macroeconomics research has changed profoundly since the Kydland-Prescott seminal paper. In order to address the Lucas Critique, modeling is now based on micro-foundations treating agents as rational utility optimizers. Bayesian estimation has produced models which are more data-consistent than those based simply on calibration. With micro-foundati...
We introduce adaptive learning behavior into a general-equilibrium life-cycle economy with capital accumulation. Agents form forecasts of the rate of return to capital assets using least-squares autoregressions on past data. We show that, in contrast to the perfect-foresight dynamics, the dynamical system under learning possesses equilibria that ar...
