Information is “market-consistent” if agents only use market prices to infer the underlying states of the economy. This paper applies this concept to a stochastic growth model with incomplete markets and heterogeneous agents. The economy with market-consistent information can never replicate the full information equilibrium, and there are substantial differences in impulse responses to aggregat...

We consider an exchange economy under uncertainty, in which agents’ utility functions exhibit constant absolute risk aversion, but they may be recursive and the expected utility calculation may be based on multiple subjective beliefs. The risk aversion coefficients, subjective beliefs, subjective time discount factors, initial endowments, and tradeable assets may differ across agents. We prove ...

We associate to any pure exchange economy a game with only two players, regardless of the number of consumers. In this twoplayer game, each player represents a different role of the society, formed by all the individuals in the economy. Player 1 selects feasible allocations trying to make Pareto improvements. Player 2 chooses an alternative from the wider range of allocations that are feasible ...

While most of the literature starting with Shapley and Scarf (1974) have considered a static exchange economy with indivisibilities, this paper studies the dynamics of such an economy. We find that both the dynamics generated by competitive equilibrium and the one generated by weakly dominance relation, converge to a set of allocations we define as strictly stable, which we can show to exist. M...

This note offers a general proof of the converse of Hartwick’s rule, namely that — in an economy with stationary instantaneous preferences and a stationary technology — an efficient constant utility path is characterized by the value of net investments being zero at each point in time. In a one consumption economy with two stocks — a stock of a natural resource and a stock of man-made capital —...

In this paper we examine whether past returns of the market portfolio (MKT), the size portfolio (SMB), the book-to-market portfolio (HML) and the idiosyncratic volatility portfolio (HIMLI) can predict growth rates of ten major Australian economic indicators from 1993 to 2010. We find that all four factors can be used to predict growth rates in Australian economic indicators. We also find high r...

This article investigates the effects and transmission channels of shocks between two asymmetric neighboring countries. In particular, we investigate Austria and Germany which are highly integrated due to their common language and common membership of the European Monetary Union. Generalized impulse response functions reveal that there are large and significant effects of shocks to the German e...

We characterize the Pareto correspondence, the core and the Walras solution using the axioms of consistency, converse consistency and one-person rationality. Consistency and its converse are defined with respect to suitably constructed reduced economies for each case. Our results hold for the well-known class of coalitional production economies, which covers exchange economies as a particular c...

The paper analyzes how social barriers to communication affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labor, a negative relationship is shown to exist between social barriers to communication and total factor productivity (TFP), per capita consumption and reproducible cap...

We analyze the stability of monetary regimes in an economy where fiat money is endogenously created by the government, information about its value is imperfect, and learning is decentralized. We show that monetary stability depends crucially on the speed of information transmission in the economy. Our model generates a dynamic on the acceptability of fiat money that resembles historical account...
