This paper compares numerical solutions to the model of Krusell and Smith [1998. Income and wealth heterogeneity in the macroeconomy. Journal of Political Economy 106, 867-896] generated by different algorithms. The algorithms have very similar implications for the correlations between different...

This paper describes the first model considered in the computational suite project that compares different numerical algorithms. It is an incomplete markets economy with a continuum of agents and an inequality (borrowing) constraint.

We propose a method to solve models with heterogeneous agents and aggregate uncertainty. The law of motion describing aggregate behavior is obtained by explicitly aggregating the individual policy rule. The algorithm is simpler and faster than existing algorithms that rely on parameterization of...

In many auctions, the auctioneer is an agent of the seller. This invites corruption. We analyze a model in which the auctioneer orchestrates bid rigging by inviting a bidder to either lower or raise his bid, whichever is more profitable. The interplay between these two types of corruption gives...

We study monetary policy in a reduced-form dynamic model with bounded rationality and an empirically motivated investment function. Investment has important dynamic effects in our model. In particular, the cost of capital effect on investment is more important for monetary transmission than the...

In this paper, we take an analytical approach to examine possible adverse effects of the use of inflation targeting as a disinflation regime. The idea is that a strict interpretation of an inflation target may preserve inflationary distortions after price stability is attained. We show that such...

We introduce learning in a principal-agent model of output sharing under moral hazard. We use social evolutionary learning to represent social learning and reinforcement, experience-weighted attraction (EWA) and individual evolutionary learning (IEL) to represent individual learning. Learning in...

I construct a model of an economy whose government finances volatile public spending via money creation. The model jointly accounts for the emergence of some well-known empirical observations. Specifically, it predicts a negative correlation between output growth and policy volatility....

In this paper, we use the generalized Taylor economy (GTE) framework to examine the optimal choice of inflation index. In this otherwise standard dynamic stochastic general equilibrium (DSGE) model, there can be many sectors, each with a different contract length. In the GTE framework with an...

The pattern of joining the labor force only at an advanced stage of the life-cycle was widespread among American women in the 1960s and 1970s, but not since the 1980s. To explain this change we conduct a theoretical analysis of the interrelation between women's lifetime labor supply choices and...
