Business cycle fluctuations and the cost of insurrance in computable heterogeneous agent economies

In this paper I study the business cycle implications of alternative insurance technologies using a computable general equilibrium heterogeneous agent environment. I find that the limited monetary arrangement entails larger fluctuations in hours relative to productivity than those that obtain in an identical economy where every risk is costlessly insurable. I also find that in the monetary economy the price level displays a markedly countercyclical behavior. Finally I evaluate the welafare costs of the monetary self-insurance arrangement

Capital Versus Labor Taxation with Heterogeneous Agents

We investigate the welfare implications of eliminating a proportional capital income tax for a model economy in which heterogeneous households face labor income risk and trade only one asset. Labor taxes rises at the time of the reform to maintain long run budget balance. Our stochastic process for labor earnings is consistent with empirical estimates of earnings risk, and also implies a distribution of asset holdings across households closely resembling that in the United States. We find that a vast majority of households prefers the status quo to the tax reform. This finding is interesting in light of the fact that our reform would be optimal if we abstracted from heterogeneity and assumed a representative agent. Initial household productivity and initial household wealth are independently important in determining a particular household's expected gain or loss, in contrast to a complete markets economy in which only the ratio of asset to labor income matters.

The Labour Market in CGE Models

This paper reviews options of labour market-modelling in a CGE framework. On the labour-supply side, two principal modelling options are distinguished and discussed: aggregated, representative households and microsimulation based on individual household data.On the labour-demand side, we focus on the substitution possibilities between different types of labour in production.With respect to labour-market coordination, we discuss several wage-forming mechanisms and involuntary unemployment. � �

Winners and Losers in Housing Markets

This paper is a quantitatively-oriented theoretical study into the interaction between housing prices, aggregate production, and household behaviour over a lifetime. We develop a life-cycle model of a production economy in which land and capital are used to build residential and commercial structures. We find that, in an economy where the share of land in the value of structures is large, housing prices react more to an exogenous change in expected productivity or the world interest rate, causing large redistribution effects between net buyers and net sellers of houses. Changing the financing constraint, however, has limited effects on housing prices.Real estates, Land, Housing Prices, Life cycle, Collateral constraints.

Monetary policy in a non-representative agent economy: A survey

It is well-known that central bank policies affect not only macroeconomic aggregates, but also their distribution across economic agents. Similarly, a number of papers demonstrated that heterogeneity of agents may matter for the transmission of monetary policy on macro variables. Despite this, the mainstream monetary economics literature has so far been dominated by dynamic stochastic general equilibrium (DSGE) models with representative agents. This article aims to tilt this imbalance towards heterogeneous agents setups by surveying the main positive and normative findings of this line of the literature, and suggesting areas in which these models could be implemented. In particular, we review studies that analyze the heterogeneity of (i) households’ income, (ii) households’ preferences, (iii) consumers’ age, (iv) expectations, and (v) firms’ productivity and financial position. We highlight the results on issues that, by construction, cannot be investigated in a representative agent framework and discuss important papers modifying the findings from the representative agent literature.Heterogeneous Agents; Monetary Policy

Do Consumers React to the Shape of Supply? Water Demand under Heterogeneous Price Structures

Urban water pricing provides an opportunity to examine whether consumers react to the shape of supply functions. We carry out an empirical analysis of the influence of price and price structure on residential water demand, using the most price-diverse, detailed, household-level water demand data yet available for this purpose. We adapt the Hausman model of labor supply under progressive income taxation to estimate water demand under non-linear prices. Ours is the first analysis to address both the simultaneous determination of marginal price and water demand under block pricing and the possibility of endogenous price structures in the cross section. In order to examine the possibility that consumers facing block prices are more price-responsive, all else equal, we test for price elasticity differences across price structures. We find that households facing block prices are more sensitive to price increases than households facing uniform marginal prices. Tests for endogenous price structures cannot rule out a behavioral response to the shape of supply, but suggest that observed differences in price elasticity under supply curves of varying shapes may result, in part, from underlying heterogeneity among utility service areas.Non-linear pricing, water demand, price elasticity

Land Use Controls and the Provision of Education

Considerable prior analysis has gone into the study of zoning restrictions on locational choice and on fiscal burdens. The prior work on zoning - particularly fiscal or exclusionary zoning - has provided both inconclusive theoretical results and quite inconsistent empirical support of the theory. More importantly, none of this work addresses important questions about the level and distribution of public goods that are provided under fiscal zoning. Since fiscal issues and Tiebout demands are central to much of the motivation for exclusionary zoning, we expand the theoretical analysis to encompass the interplay between land use restrictions and public good provision. In this, we focus on schooling outcomes, since the provision of education is one of the primary activities of local jurisdictions. We develop a general equilibrium model of location and the provision of education. Some households create a fiscal burden, motivating the use by local governments of exclusionary land-use controls. Then, the paper analyzes what the market effects of land-use controls are and how successful they are. The policies considered (minimum lot size zoning, local public finance with a head tax, and fringe zoning) demonstrate how household behavior directly affects the equilibrium outcomes and the provision of the local public good.

Tax structure, welfare, and the stability of equilibrium in a model of dynamic optimal fiscal policy

A demonstration that the assumed structure of taxation can have dramatic effects on economic welfare and on the stability of the steady state in a dynamic general-equilibrium model of optimal fiscal policy. The authors find that household welfare is highest under a structure that includes separate tax rates on labor and capital incomes, double taxation of dividends, and tax-deductible depreciation.Taxation ; Fiscal policy
