Functional time series and high-dimensional scalar predictors frequently arise ina wide range of modern economic and business applications, which require statisticalmodels that can simultaneously handle the temporal and causal dependence that areprevalent in large sets of mixed-type data. We...

About 23% of the German energy demand is supplied by natural gas. Additionally, for about the same amount Germany serves as a transit country. Thereby, the German network represents a central hub in the European natural gas transport network. The transport infrastructure is operated by...

A deeper understanding of cloud computing is required to accelerate its adoption and leverage its cost, performance, reliability, and security. However, information about the combined effect of factors influencing cloud computing adoption using traditional statistical methods is limited. Based...

Subsidies to consumers may cause firms to charge higher prices, which offsets consumer benefits from subsidies. We study a subsidy program design that mitigates such price increases by making products' eligibility for a subsidy dependent on firms' commitment to price ceilings. To quantify the...

In this paper, we study the performance of hated stocks, those stocks with the average analyst recommendation level of hold or worse. We show that from the beginning of 2009 to the end of 2014, this group of hated stocks in S&P 500 performs better than the other stocks in S&P 500. When we extend...

In this paper, we study leveraged ETFs, in particular, Ultra ETFs and UltraShort ETFs from the ProShares family. These Ultra (UltraShort) ETFs are designed to provide twice (twice the opposite) of the performance of the benchmark on a daily basis. We focus on the relation between long term...

This paper examines block transactions in Chinese equity market. We find that most of the block transactions are traded at prices at or below the closing price of the regular continuous auction market, and more than half are traded at or below the lowest price of the day. While the block...

We develop a novel large-scale Network Autoregressive model with balance Constraint (NAC) to predict hour-ahead gas flows in the gas transmission network, where the total in- and out-flows of the network are balanced over time. By integrating recent advances in optimization and statistical...
