Blundell, Pistaferri, and Preston use panel data on household consumption and income inequality to evaluate the degree of insurance against income shocks. They aim to describe the transmission of income inequality into consumption inequality. Their framework nests the special cases of self-insurance and the complete markets assumption. The authors assess the degree of insurance, over and above self-insurance through savings, by contrasting shifts in the distribution of income growth with shifts in the distribution of consumption growth, and analyzing the way these two measures of household welfare correlate over time. Combining panel data on income with consumption data, they find some partial insurance but reject the complete markets restriction. They also find a greater degree of insurance for transitory shocks and differences in the degree of insurance over time. Finally, they document the importance of durables and of taxes and transfers as a means of insurance.

Hornstein, Krusell, and Violante argue that certain ingredients are likely to be important for understanding how wage distributions and employment respond to technology. First, it matters whether there are labor market frictions. Matching frictions, and associated departures from marginal-product wage determination, are important. Second, the form of technological change matters. …
