An evaluation of the performance of an applied general equilibrium model of the Spanish economy
In 1985?86 the authors were members of a team that constructed a static applied general equilibrium model that was used to analyze the impact on the Spanish economy of the 1986 fiscal reform, which accompanied Spain?s entry into the European Community. This paper compares the results obtained to recently published data for 1985?87; we find that the model performed well in predicting the changes in relative prices and resource allocation that actually occurred, particularly if we incorporate exogenous shocks that affected the Spanish economy in 1986. We also analyze the sensitivity of the ...

Privately optimal contracts and suboptimal outcomes in a model of agency costs
This paper derives the privately optimal lending contract in the celebrated financial accelerator model of Bernanke, Gertler and Gilchrist (1999). The privately optimal contract includes indexation to the aggregate return on capital, household consumption, and the return to internal funds. Although privately optimal, this contract is not welfare maximizing as it leads to a sub-optimally high price of capital. The welfare cost of the privately optimal contract (when compared to the planner outcome) is significant. A menu of time-varying taxes and subsidies can decentralize the planner?s ...

An estimated DSGE model for the United Kingdom
The authors estimate the dynamic stochastic general equilibrium model of Christiano, Eichenbaum, and Evans (2005) on U.K. data. Their estimates suggest that price stickiness is a more important source of nominal rigidity in the United Kingdom than wage stickiness. Their estimates of parameters governing investment behavior are only well behaved when post-1979 observations are included, which reflects government policies until the late 1970s that obstructed the influence of market forces on investment.

Social accounting matrices and applied general equilibrium models
To illustrate the use of social accounting matrices (SAMs) in applied general equilibrium (GE) modeling, we use an aggregated SAM for the Spanish economy to calibrate a simple applied GE model. The idea is to construct artificial people - households, government, and a foreign sector - who make the same transactions in the equilibrium of the model economy as do their counterparts in the data. This calibration procedure can be augmented, or partially substituted for, by statistical estimation of key parameters. We show the usefulness of such a model by presenting the results of a comparative ...

Neighborhood dynamics and the distribution of opportunity
This paper uses an overlapping-generations dynamic general equilibrium model of residential sorting and intergenerational human capital accumulation to investigate effects of neighborhood externalities. In the model, households choose where to live and how much to invest toward the production of their child?s human capital. The return on the parent?s investment is determined in part by the child?s ability and in part by an externality from the average human capital in their neighborhood. We use the model to test a prominent hypothesis about the concentration of poverty within ...

The price puzzle and indeterminacy in an estimated DSGE model
We extend Lubik and Schorfheide's (2004) likelihood-based estimation of dynamic stochastic general equilibrium (DSGE) models under indeterminacy to encompass a sample period including both determinacy and indeterminacy by implementing the change-point methodology (Chib, 1998). The most striking finding about the indeterminacy regime, which is estimated to coincide with the Great Inflation of the 1970s, is that it exhibits the price puzzle, in that the inflation rate rises immediately and in a sustained manner following a positive interest rate shock. Thus, the price puzzle might have been a ...

Looking for evidence of time-inconsistent preferences in asset market data.
This study argues that strong evidence contradicting the traditional assumption of time-consistent preferences is not available. The study builds and analyzes the implications of a deterministic general equilibrium model and compares them to data from the U.S. asset market. The model implies that (1) because of dynamic arbitrage, the prices of retradable assets cannot reveal whether preferences are time-inconsistent; but (2) the prices of commitment assets, investments which must be held for their lifetime, can. These prices will be higher than the present values of their future payoffs only ...

On the equilibrium concept for overlapping generations organizations
A necessary feature for equilibrium is that beliefs about the behavior of other agents are rational. We argue that in stationary OLG environments this implies that any future generation in the same situation as the initial generation must do as well as the initial generation did in that situation. We conclude that the existing equilibrium concepts in the literature do not satisfy this condition. We then propose an alternative equilibrium concept, organizational equilibrium, that satisfies this condition. We show that equilibrium exists, it is unique, and it improves over autarky without ...
