The labor force participation rates of men and women aged 62-79 have notably increased since the mid-1990s. The result is a dramatic increase in the share of total money income attributable to earnings. For persons aged 65-69, the earnings share of total income increased from 28 percent in 1980 to 42 percent in 2009. For this age group in the late 1980s and early 1990s, Social Security benefits...

This paper presents a new empirical strategy for estimating the effects of trade policy on domestic factor prices when policy endogeneity is suspected. Absent income effects on factor supplies or domestic prices, the coefficient on the terms of trade can provide an unbiased estimator of the effect of trade barriers on the factor distribution of income for a small economy. In the more general ca...

Abstract We analyse top income and wealth shares data, by conducting a robust estimation of trends, tests for structural breaks, determining persistence. include Anglo-Saxon countries, continental Europe Asian grouped under different percentiles deciles, spanning period that is at least close to century. find the almost all countries are characterised broken or level shifts. The preponderance t...

Purchase shares of major national-brands in consumer packaged-goods industries vary substantially across stores, both between markets and within markets. This paper measures the extent to which this variation in national-brand purchase shares depends on store-specific supply decisions, which are traditionally within the purview of trade marketing. We first demonstrate the extent to which purcha...

We propose a unitary procedure to reconstruct quantum secret for a quantum secret sharing scheme constructed from stabilizer quantum errorcorrecting codes. Erasure correcting procedures for stabilizer codes need to add missing shares for reconstruction of quantum secret while unitary reconstruction procedures for certain class of quantum secret sharing are known to work without adding missing s...
