Recommender systems have been widely used by online stores to suggest items of interest to users. These systems often identify a subset of items from a much larger set that best matches the user's interest. A key concern with existing approaches is over-specialization, which results in returning...

Understanding the relationship between itineraries displayed on an air travel website’s shopping screens and the website’s market share has never been so important nowadays. This paper presents an approach to measure ‘screen quality’, that is, the overall desirability of itineraries...

This paper investigates the liquidity transmission of traditional and structural monetary policy instruments in the interbank market and their effects on bank credit growth based on 107 banks from 2005Q4 to 2020Q4 in China. We find that the credit channel of monetary policy differs across banks...

The identifiability and estimability of the parameters for the Unified Cognitive/IRT Model are studies. A calibration procedure for the Unified Model is then proposed. This procedure uses the marginal maximum likelihood estimation approach and utilizes the EM algorithm. It differs from other...

By using the data of Chinese firms with the state ownership structure, we examine whether institutional investors can help reduce the required return of equity for state-owned enterprises (SOEs) and non-SOEs. We find that an increase in the shareholdings of institutions especially independent...

We study the multiproduct price optimization problem under the multilevel nested logit model, which includes the multinomial logit and the two-level nested logit models as special cases. When the price sensitivities are identical within each primary nest, that is, within each nest at level 1, we...

Using data on Chinese firms with the unique state ownership structure of state-owned enterprises (SOEs), we examine whether institutional investors can help reduce the required returns on equity for SOEs or non-SOEs, and if so, the underlying channels. We find that an increase in the...

Unconventional intersection designs have been used to increase the capacity of intersections that are over-saturated under conventional ones. However, existing unconventional designs typically require extra land space and their effectiveness often depends on drivers' familiarity with the...

It is well recognized that the left turn reduces the intersection capacity significantly, because some of the tra ffic lanes cannot be used to discharge vehicles during its green phases. In this paper, we operationalize the phase swap sorting strategy (Xuan, 2011) to use most, if not all, traffi...
