A Composite Likelihood Approach for Dynamic Structural Models
We describe how to use the composite likelihood to ameliorate estimation, computational, and inferential problems in dynamic stochastic general equilibrium models. We present a number of situations where the methodology has the potential to resolve well-known problems. In each case we consider, we provide an example to illustrate how the approach works and its properties in practice.
Inflation, Volatility, and Growth
This paper re-examines the relationship between inflation, inflation volatility and growth using cross-country panel data for the past 30 years. With regard to the level of inflation, we find that in contrast to current findings which are based on cross-sectional time-average regression comparisons, exploiting the time dimension of the data reveals a strong negative correlation between inflation and income growth for all but very low inflation countries. To examine the role of inflation uncertainty on growth, we use intra-year inflation data to construct an annual measure of inflation ...
Household Saving and Portfolio Change: Evidence from the 1983-89 SCF Panel
There are very few sources of high-quality data on the dynamics of wealth accumulation. This paper uses newly-available data from the 1983-89 panel of the Survey of Consumer Finances to examine household saving and portfolio change over the 1980s. The 1983 SCF collected detailed information on households' assets, liabilities, income and other characteristics for a sample of 4,103 families. In 1989, 1,479 of these families were re-interviewed using a similar questionnaire. After describing the sample and methodology of the panel survey, we analyze changes in household wealth over the 1983-89 ...
Do Low Human Capital Coefficients Make Sense? A Puzzle and Some Answers
I develop a new measure of human capital stock that has two advantages over previous measures. First, it allows for varying costs of education across time, countries, and level of education. Second, the unit of measurement is dollars, which allows comparison of human capital stocks with other macro- economic variables, including national income (GDP) and physical capital stocks. Using cross-country panel regression analysis, I find that human capital accumulation accounts for a relatively small (about ten percent) of per-capita GDP growth. I further find that, unlike physical capital, the ...
Estimating Taxable Income Responses with Elasticity Heterogeneity
We extend a standard taxable income model with its typical functional-form assumptions to account for nonlinear budget sets. We propose a new method to estimate taxable income elasticity that is more policy relevant than the typically estimated elasticity based on linearized budget sets. Using U.S. data from the NBER tax panel for 1979-1990 and differencing methods, we estimate an elasticity of 0.75 for taxable income and 0.20 for broad income. These estimates are higher than those obtained by specifications based on linearization. Our approach offers a new way to address the problem of ...
