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...

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...

In 2019, President Trump called on the U.S. Federal Reserve to cut interest rates to depreciate the U.S. dollar, which, according to the IMF, is overvalued by between 6 and 12 percent. This paper uses an intertemporal general equilibrium model to explore what would likely happen if the...

Continued automation and declines in low-skill shares of GDP have been widespread globally and linked to inequality. We examine the long-term, global consequences of policies that foster automation or address the distributional consequences of it, using a six-region global macro model. Results...

Productivity growth has flat-lined in most economies despite rapid advances in technology. Economists suggest competing explanations for this paradox. Some argue the current stagnation will persist given deep structural challenges, arguing that recent technological advances are no match for...
