The Abstract: Importing Culture

A roundup of noteworthy research:

Which Immigrants Like Redistributive Policies?
To separate the effect of culture from the effect of the economic and institutional environment ("context"), we relate immigrants' preferences for redistribution to the average preference in their birth countries...We find a strong positive relationship.  This cultural effect is larger for non-voters, those with shorter tenure in the country of residence, and those who move to countries with a large number of immigrants from their own birth countries. Immigrants from countries with a higher preference for redistribution are also more likely to vote for a more pro-redistribution political party. The effect of culture persists strongly into the second generation.
Income Inequality Since 1993 Driven by Top 1%
...we analyze trends in US income inequality (1975-2004). We find that the upward trend in income inequality prior to 1993 significantly slowed thereafter once we control for top coding in the public use data and censoring in the internal data...When we compare our best estimates of the income shares held by the richest tenth with those reported by Piketty and Saez (2003), our trends fairly closely match their trends, except for the top 1 percent of the distribution. Thus, we argue that if United States income inequality has been substantially increasing since 1993, such increases are confined to this very high income group.

What Would Happen to Tax Revenue If Mortgage Interest Deduction Was Eliminated?
This one is co-written by new NBER president James Poterba: We estimate that repealing the mortgage interest deduction in 2003 would have raised income tax revenues by $72.4 billion in the absence of any portfolio adjustments, but by only $61.9 billion if homeowners responded by drawing down a limited set of financial assets to partially replace their mortgage debt.  The revenue effects of changing the property tax deduction similarly depend on how state and local governments alter their mix of revenue instruments in response to federal tax reform.  Our results underscore the importance of recognizing behavioral responses when calculating the revenue costs of income tax provisions relating to owner-occupied housing.
