Estimating Substitution Elasticities in Household Production Models

SummaryDynamic general equilibrium models that include explicit household production sectors provide a useful framework within which to analyze a variety of macroeconomic issues. However, some implications of these models depend critically on parameters, including the elasticity of substitution between market and home consumption goods, about which there is little information in the literature. Using the PSID, we estimate these parameters for single males, single females, and married couples. At least for single females and married couples, the results indicate a high enough substitution elasticity that including home production will make a significant difference in applied general equilibrium theory.

On the Political Economy of Income Redistribution and Crime

In this paper we consider a general equilibrium model where heterogeneous agents specialize either in legitimate market activities or in criminal activities and majority rule determines the share of income redistributed and the expenditures devoted to the apprehension of criminals. We calibrate our model to the U.S. economy in 1990, and we conduct simulation exercises to evaluate the effectiveness of expenditures on police protection and income redistribution at reducing crime. We find that while expenditures on police protection reduce crime, it is possible for the crime rate to increase with redistribution. We also show that economies that adopt relatively more generous redistribution policies may have either higher or lower crime rates than economies with relatively less generous redistribution policies, depending on the characteristics of their wage distribution and on the efficiency of their apprehension technology.

Home Production Meets Time to Build

An innovation in this paper is to introduce a time‐to‐build technology for the production of market capital into a model with home production. Our main finding is that the two anomalies that have plagued all household production models—the positive correlation between business and household investment, and household investments leading business investment over the business cycle—are resolved when time to build is added.

Homework in labor economics: Household production and intertemporal substitution ☆

We argue that estimates of intertemporal substitution elasticities obtained from standard life cycle models are subject to a downward bias because they neglect changes in work done at home over the life cycle. We extend the standard life cycle model to include home production and estimate it using data from three time use surveys. We find that the downward bias is large.

Measuring labor’s share of income

Recent Bureau of Labor Statistics (BLS) data show labor’s share of income at a historic low. This Policy Discussion Paper explores the BLS calculations with an eye to understanding the factors leading to the recent fall in labor’s share. While data limitations prohibit replication of the BLS series, alternative measures of labor’s share of income, based on either the nonfinancial corporate business sector or the macroeconomy more generally, are near their historic averages, quite unlike the BLS series.

Housing and the Labor Market: Time to Move and Aggregate Unemployment

The Mortensen-Pissarides model with unemployment benefits and taxes has been able to account for the variation in unemployment rates across countries but does not explain why geographical mobility is very low in some countries (on average, three times lower in Europe than in the U.S.). We build a model in which both unemployment and mobility rates are endogenous. Our findings indicate that an increase in unemployment benefits and in taxes does not generate a strong decline in mobility and accounts for only half to two-thirds of the difference in unemployment from the US to Europe. We find that with higher commuting costs the effect of housing frictions plays a large role and can generate a substantial decline in mobility. We show that such frictions can account for the differences in unemployment and mobility between the US and Europe.

Generalized search-theoretic models of monetary exchange

This paper extends the literature on search-theoretic models of money in several ways. It provides results for general bargaining parameters, whereas previous papers consider only special cases. It also presents one version of the model in which agents holding money cannot produce and another in which they can. The former has been used in essentially all the previous literature, although the latter seems more natural for some purposes and avoids several undesirable implications. Since very little is known about this version, the authors analyze it in detail.

General equilibrium with nonconvexities and money

In a general-equilibrium economy with nonconvexities, there are sunspot equilibria with good welfare properties; sunspots can ameliorate the effects of the nonconvexities. For these economies, we show that agents act as if they have quasi-linear utility functions. We use this result to construct a new model of monetary exchange along the lines of Lagos and Wright, where trade occurs in both centralized and decentralized markets, but instead of quasi-linear preferences we assume general preferences but with indivisible labor. This suggests that modern monetary theory is more robust than one might have thought. It also constitutes progress on the classic problem of integrating monetary economics and general-equilibrium theory.

Housing dynamics over the business cycle

Over the U.S. business cycle, fluctuations in residential investment are well known to systematically lead GDP. These dynamics are documented here to be specific to the U.S. and Canada. In other developed economies residential investment is broadly coincident with GDP. Nonresidential investment has the opposite dynamics, being coincident with or lagging GDP. These observations are in sharp contrast with the properties of nearly all business cycle models with disaggregated investment. Including mortgages and interest rate dynamics aligns the theory more closely with U.S. observations. Longer time to build in housing construction makes residential investment coincident with output.

Understanding the Determinants of Crime

In this paper, we use an overlapping generations model where individuals are allowed to engage in both legitimate market activities and criminal behavior in order to assess the role of certain factors on the property crime rate. In particular, we investigate if differences in the unemployment rate, fraction of low human capital individuals in an economy, apprehension probability, duration of a jail sentence, and income inequality could be capable of generating large differences in crime rates that are observed across countries. We find that small differences in the apprehension probability and income inequality can generate quantitatively significant differences in the crime rates across similar environments.
