This paper develops a dynamic general equilibrium model with heterogeneous firms that face search complementarities in the formation of vendor contracts. Search complementarities amplify small differences in productivity among firms. Market concentration fosters monopsony power in the labor...

We estimate a medium-scale model with and without rule-of-thumb consumers over the pre- Volcker and the Great Moderation periods, allowing for indeterminacy. Passive monetary policy and sunspot fluctuations characterize the pre-Volcker period for both models. The estimated fraction of...

The world will experience dramatic demographic change over this century. This paper examines the impacts of this global demographic change on the Australian economy at both the aggregate and sectoral levels in a global multi-region and multi-sector general equilibrium model. Using a detailed...

The world has been experiencing dramatic demographic change since the 1950s, with almost all countries facing ageing challenges this coming century. However, the timing and speed of this demographic transition are significantly asymmetric across countries. This paper examines the impacts of...

This paper provides a framework to endogenize rates of return for risk-free bonds and risky capital in an overlapping generation model. The rate of return on capital is endogenized by introducing idiosyncratic production shocks to avoid computation challenges associated with aggregate production...

We present a new approach to the approximation of equilibrium solutions to nonlinear rational expectations models that applies to any order of approximation. The approach relies on a particular version of Taylor series approximations -- the differential version -- and on a scalar perturbation of...

This paper presents a simple and fast maximum likelihood estimation method for nonlinear DSGE models that are solved using a second- (or higher-) order accurate approximation. The method requires that the number of observables equals the number of exogenous shocks. Exogenous innovations are...

This paper develops a novel approach for estimating latent state variables of Dynamic Stochastic General Equilibrium (DSGE) models that are solved using a second-order accurate approximation. I apply the Kalman filter to a state-space representation of the second-order solution based on the...

This paper explores the role of demand from emerging and developed economies as drivers of the real price of oil. Using a method that allows us to identify and compare demand from different groups of countries across the world, we find that demand from emerging economies (most notably from Asian...

This paper documents two facts: (i) elasticities of substitution in production vary significantly across sectors, with manufacturing sectors being generally less flexible than service sectors, and (ii) during the Great Recession the rise in bond spreads varied systematically with these...
