Reconciling Micro And Macro Estimates Of The Frisch Labor Supply Elasticity

Reconciling Micro and Macro Estimates of the Frisch Labor Supply Elasticity

This paper explores the large gap between the microeconometric estimates of the Frisch labor supply elasticity (0-.5) and the values used by macroeconomists to calibrate general equilibrium models (2-4). These two ranges identify two fundamentally different notions, the micro and macro Frisch elasticity, respectively. Due to the different definitions, there are two restrictions in the micro Frisch elasticity that are relaxed in the macro Frisch elasticity. First, the micro Frisch elasticity focuses only on prime-aged married males who are the head of their household, while the macro Frisch elasticity represents the whole population. Second, the micro Frisch elasticity only incorporates intensive margin fluctuations in hours, while the macro Frisch elasticity includes both intensive and extensive margin fluctuations. This paper finds that relaxing these two restrictions causes estimates of the Frisch elasticity to increase from 0.2 to between 2.9 and 3.1, indicating that these two restrictions can explain the gap between the microeconometric estimates and the calibration values. However, this paper demonstrates that these estimates of the macro Frisch elasticity are sensitive to the estimation procedure and also the exclusion of older individuals, implying that calibration values used for macroeconomic models should be selected carefully.

The Economics of the Family

A fascinating look at the role that households—and the dynamics of families, in particular—play in creating economic growth and social stability in modern economies and markets. This timely compilation of essays examines the paradigm of family in the 21st century, delving into cohabitation, marriage, and divorce; the effects of modern family units on work and consumption; and the ramifications of life choices on economic growth and stability. The text ponders highly personal yet societal topics, such as who lives with whom and why; the reasons for low birth rates among highly educated, high-income women; and strategies busy parents use to balance career, parenthood, and personal life. Volume I explores the various profiles of families today, covering multi- or single-generational, single or dual parent, and same- or opposite-sex couples. Volume II considers how time and money are shared among family members and what impact this distribution of resources has on occupations, technology, and markets. The text scrutinizes the factors that drive family formation and dissolution, control population in countries all over the world, and contribute to a family's well-being and fortitude.
