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...

This paper introduces heterogeneous microeconomic behavior into a demand-driven stock-flow consistent model with endogenous credit creation, so as to study the joint dynamics of both the personal and the functional distribution of income, household debt and aggregate demand. The distinctive...

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 evaluates how initial beliefs uncertainty can affect data weighting and the estimation of models with adaptive learning. One key finding is that misspecification of initial beliefs uncertainty, particularly with the common approach of artificially inflating initials uncertainty to...

The paper presents a sparse grid approximation method based on the hyperbolic cross and applies it to solve non-linear macroeconomic models. We show how the standard hyperbolic cross can be extended to give greater control over the approximating grid and we discuss how to implement an...

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...

We estimate a small-scale nonlinear DSGE model with the zero lower bound (ZLB) of the nominal interest rate for Japan, where the ZLB has constrained the country's monetary policy for a considerably long period. We employ the time iteration with linear interpolation method to solve equilibrium...
