Dynamic models with inequality constraints pose a challenging prob- lem for two major reasons: Dynamic Programming techniques often necessitate a non established differentiability of the value function, while Euler equation based techniques have problematic or unknown convergence properties....

The money-age distribution is found to be hump-shaped for the US economy. The variation (inequality) of cash holdings within generations increases (declines) with age. Furthermore, cash holdings are found to be only weakly correlated ith both income and wealth. We analyze three motives for money...

We introduce a ''new'' algorithm that can be used to solve stochastic dynamic general equilibrium models. This approach exploits the fact that the equations defining equilibrium can be viewed as set of algebraic equations in the neighborhood of the steady-state. Then a recursive scheme, which...

This paper investigates the process of deriving a single decision solely based on the decisions made by a population of experts. Four different amalgamation processes are studied and compared among one another, collectively referred to as central decision makers. The expert, also referred to as...

Existing search-theoretical model of money have in general abstracted from the existence and accumulation of other assets, in particular, capital. In this paper we present a model where the optimal portfolio allocation decision of agents is explicitly modeled. Trade frictions in a decentralized...

Over the last 20 years, the annual average U.S. and Canadian productivity growth rates have been 2.3% and 1.3%, respectively. The objective of this paper is twofold. First, we empirically document the firm size distribution and the productivity for the two countries. Second, we quantitatively...

We employ a new decision-theoretic approach to dealing with Knightian uncertainty based on Simon's bounded rationality. The basic tool of this approach is a quantitative answer to the question: For a specified policy, among a set of policies, how much can our assumptions regarding e.g. model and...

Recent empirical work documents substantial disagreement in inflation expectations obtained from survey data. Furthermore, the extent of such disagreement varies systematically over time in a way that reflects the level and variance of current inflation. This paper offers a simple explanation...

The purpose of this paper is to present a new approach to evaluating structural change of the economy in a multisector general equilibrium framework. The multiple calibration technique is applied to an ex post decomposition analysis of structural change between periods, enabling the distinction...

Apart from the risk premium of equity over bonds, volatility of asset prices and trading volumes are two aspects of the already developed general equilibrium asset pricing theory that fail to show any resemblance with real data. The assumption of agent homogeneity has been relaxed in a number of...
