In the presence of context effects, the perceived attractiveness of individual items is not fixed and depends on other items that are offered beside them. While context effects are well explored in the marketing and psychology literature, very little work has been done on incorporating these...

This paper studies a capacity management problem with upgrading. A firm needs to procure multiple classes of capacities and then allocate the capacities to satisfy multiple classes of customers that arrive over time. A general upgrading rule is considered, i.e., unmet demand can be satisfied...

Superstition is prevalent in rural areas, yet very few studies examine whether it affects rural households’ economic decisions. In this paper, we investigate the impact of “zodiac year” superstition on Chinese rural households’ life insurance spending. We find a statistically significant...

Exploiting a screen display feature whereby the order of stock display is determined by the stock listing codes, we lever a novel identification strategy and study the impact of attention spillover on stock prices and turnover. We find that stocks with neighbors on the display that experience...

Estimation of the covariance matrix of asset returns is crucial to portfolio construction. As suggested by economic theories, the correlation structure among assets differs between emerging markets and developed countries. It is therefore imperative to make rigorous statistical inference on...

In general, gradient estimates are very important and necessary for deriving convergence results in different geometric flows, and most of them are obtained by analytic methods. In this paper, we will apply a stochastic approach to systematically give gradient estimates for some important...

C60 films were fabricated by vacuum sublimation and studied with dielectric spectroscopy regarding glass transition. With annealing, the dielectric loss peaks decreased in height, and the apparent activation energy deduced from their frequency dependence dropped in magnitude. The peaks, broad...
