TV tune-in, namely the preview of forthcoming programs, is an important type of TV advertising. We examine TV tune-in as a continuous variable. First, tune-in can increase profits when TV stations are sufficiently differentiated and the market is partially covered. Second, tune-in crowds out...

Levulinic acid (LA) is considered a very interesting green, biomass derived versatile chemical intermediate with high application potential. Herein, MOF–5 was evaluated as a perspective support to synthesize heterogeneous catalysts with Brønsted acid sites and Lewis acid sites, via simple...

Excessive borrowing of local governments in China sparked concerns that the debt may threaten the financial stability of the economy and ultimately cause economic collapse. It becomes critically important to understand the credit rating of China's LFGV bonds and the association between the...

It is common for platforms to have rules for their users to abide. Most times, users of the platform break the rules of the platform, and sometimes they get delisted or removed from the platform. Most platforms own the first party content. To the best of our knowledge, we are the first to study...

For smart phones, most apps and websites use a simplification version of the personal computer version. To the best of our knowledge, we are the first to consider the functionality of apps. We show when the equilibrium functionality is efficient, excessive or insufficient. For the case of...

We propose a framework of utility competition (UC), and we provide the intuition why price competition (PC), quantity competition (QC) and UC differ, and prove it by using a nonlinear demand system. If the network externality is positive, then PC is the most efficient with the lowest equilibrium...

In two-sided markets, instead of joining the platform simultaneously, two groups could join the platform sequentially. Under monopoly, the commitment case is equivalent to the no commitment case. With competing firms, there are two cases to consider. For case 1, if the two groups are...

We consider a Hotelling model to deal with search diversion as a continuous variable for complements and substitutes. We examine a fixed gain from trade for complements and substitutes and endogenize the gain from trade. We propose the multi-demand model with linear demand. Further, we model the...

This paper shows that reciprocity comes from the desire to cooperate in finitely repeated prisoner's dilemma game. Before playing the finitely repeated prisoner's dilemma game, players choose the reciprocity level and commit to it, and the reciprocity level is public information. There are T...
