Timing and shopping stages are two critical factors when designing personalized mobile targeting. However, there is scant evidence demonstrating the business impact of app real-time targeting on customers’ subsequent shopping behaviors across different shopping stages. By conducting a novel...

We examine the (potentially nonlinear) relationship between inequality and growth using a method which does not require an a priori assumption on the underlying functional form. This approach reveals a plateau completely missed by commonly used (nonlinear) parametric approaches - the economy...

Although the theoretical trade-off between the quantity and quality of children is well-established, empirical evidence supporting such a causal relationship − particularly on child health − is limited. We use two measures of child health to asses the quantity-quality trade-off across the...

For OECD countries there is an intriguing variety of combinations between total fertility rate (TFR) and female labor force participation rate (FPR) suggesting the existence of multiple equilibria. This paper provides a differential game framework where the employment choices by husband and wife...

In this paper, we propose a new concept of convergence which is based on the metric entropy measure recently proposed by Granger et al. (2004, Journal of Time Series Analysis 25, 649--69) to investigate economic convergence in China. This entropy measure compares whole distributions of growth...

In this paper, we propose a new concept of convergence which is based on the metric entropy measure recently proposed by Granger et al. (2004) to investigate economic convergence in China. This entropy measure compares whole distributions of growth rates across individual provinces. Separately,...

We consider the problem of testing for perfect rankings in ranked set sampling (RSS). By using a new algorithm for computing the probability that specified independent random variables have a particular ordering, we find most powerful rank tests of the null hypothesis of perfect rankings against...

This paper relaxes the assumption of homogeneous rates of return to schooling by employing nonparametric kernel regression. This approach allows us to examine the differences in rates of return to education both across and within groups. Similar to previous studies we find that on average blacks...
