In this paper we apply two statistical models to the measurement of polarization to Israeli income data over the past decade in order to empirically detect income classes as sub-populations of incomes concentrated around an optimal number of poles. The statistical models compared are a...

In this paper we study income polarization by first comparing the efficiency of two statistical models to identify the number of poles in the income distribution empirically. The statistical models used are a multi-resolution analysis (MRA) and a log-normal approach (LNA). We then apply the...

This paper introduces a real-time, continuous measure of national sentiment that is language-free and thus comparable globally: the positivity of songs that individuals choose to listen to. This is a direct measure of mood that does not pre-specify certain mood-affecting events nor assume the...

We study the relationship between employee satisfaction and abnormal stock returns around the world, using lists of the "Best Companies to Work For" in 14 countries. We show that employee satisfaction is associated with positive abnormal returns in countries with high labor market flexibility,...

This paper links the impending vesting of CEO equity to reductions in real investment. Existing studies measure the manager's short-term concerns using the sensitivity of his equity to the stock price. However, in myopia theories, the driver of short-termism is not the magnitude of incentives...

This paper studies the long-term consequences of actions induced by vesting equity, a measure of short-term incentives. Vesting equity is positively associated with the probability of a firm repurchasing shares, the amount of shares repurchased, and the probability of the firm announcing a...
