The class of generative models has already attracted considerable interest from researchers in recent years and much expanded the original ideas described in BA model. Most of these models assume that only one node per time step joins the network. In this paper, we grow the network by adding n...

With the help of the recurrence relations derived from the self-similar structure, we obtain the closed-form solution for the average path length of a class of scale-free fractal hierarchical lattices (HLs) with a general parameter q, which are simultaneously scale-free, self-similar and...

Purpose: The speed of internationalization is an important research topic in the process of internationalization. This paper aims to answer two questions: first, what is the relationship between the speed of internationalization of Chinese multinational firms and their performance? Second, how...

We study a unique grading policy at a large US public university allowing students to mask their letter grades into a "Pass", after having observed their original grade. Using administrative transcript records, we find that female students are substantially less likely to mask their grades than...

We study whether gender differences in university major choices result from anticipated labor market discrimination. First, we document two novel facts using administrative transcript records from a large Midwestern university: women are less likely to study science, technology, engineering, and...

We analyze data from two universities that allowed students to conceal grades from their transcripts during the Covid-19 pandemic. Across both institutions, we observe a significant and substantial gender concealment gap: women are less likely than men to conceal grades that would harm their...
