Outstream video advertising is becoming increasingly popular in the industry. Differing from the instream video advertisements (ads) embedded in video content, outstream video ads auto-play in non-video environments when a user navigates to them. On online shopping websites and apps, sponsored...

We propose estimators and analyze their large-sample distribution for two problems, data-oriented expected performance evaluation and data-oriented stochastic optimization, in presence of a specific class of non-stationarities in the observed data. The considered non-stationarities reflect...

The great habitat heterogeneity is a crucial contributor to the high species richness (SR) in karst forests. Yet, the driving factor behind the alterations in SR patterns during natural recovery remains unclear. In this study, forest dynamics plots were established along the natural restoration...

This paper uses loan application-level data from a Chinese peer-to-peer lending platform to study the risk-taking channel of monetary policy. By employing a direct ex-ante measure of risk-taking and estimating the simultaneous equations of loan approval and loan amount, we are the first to...

Little and An (2004) proposed a penalized spline propensity prediction (PSPP) method of imputation of missing values that yields robust model-based inference under the missing at random assumption. The propensity score for a missing variable is estimated and a regression model is fit with the...

The analysis of China's impacts on the 44 SSA countries reveals that: (i) after joining the WTO in 2001, China has started to impact significantly on SSA growth: one-percent increase in China's GDP per capita leads to 0.02 percent increase on the SSA's GDP per capita; (ii) oil and...
