It has been suggested that the size distribution of income follows a pure random walk. If true, this has serious implications for the effectiveness of U.S. Government income transfer policies. In this paper the random walk hypothesis is addressed by examining whether changes in the size distribution of income are independent. Conventional linear second-order time series analysis suggests that t...

The global burden of diabetes and cardiovascular disease (CVD) is increasing and, while event incidence falling in some high-income countries (HICs), rates are being observed many middle-income (MICs) low-income (LICs).

Economists have long been interested in determining whether increases in income cause either a stabilizing effect on a couple’s marriage or a destabilizing “independence effect”. However, estimating the effect of income on marital stability is difficult due to a lack of exogenous pure income shocks. To overcome that problem, we compare the divorce rates of winners of large cash prizes through t...
