Current Economic Policy Uncertainty (EPU) indicators are highly correlated with macroeconomic growth. To better reveal the EPU perceived by each firm, a firm-level EPU index is constructed using a text mining method. Using data of Chinese A-share listed companies from 2011 to 2020, this study...

Energy efficiency improvement is key to achieving energy conservation. Based on China's microdata from 2000 to 2010, this study systematically analyzes the impact of carbon reduction policies on energy efficiency through propensity score matching and the difference-in-differences method. The...

Utility-scale solar energy (USSE) and rooftop solar PV generate about 70% and 30% of all solar electricity. While the adoption of rooftop solar in the United States (U.S.) has been explored in depth, how USSE is spatially distributed has yet to be discussed. This study examines the spatial...

Residual coherence is a graphical tool for selecting potential second-order interaction terms as functions of a single time series and its lags. This paper extends the notion of residual coherence to account for interaction terms of multiple time series. Moreover, an alternative criterion,...

We investigate the driving factors of Chinese aid allocation to 44 African countries for the periods 2003-2017. The Poisson pseudo-maximum likelihood (PPML) procedure is applied to estimate the gravity model of aid and loan allocation as it can solve zero-valued observations and heterogeneity...

Fitting parametric models or the use of the empirical cumulative distribution function are problematic when it comes to the estimation of tail probabilities from small samples. A possible remedy is to fuse or combine the small samples with additional data from external sources and base the...

While there is a consensus on the expanding importance of the China-Africa economic relationship, there is much more debate on how to portray the relationship. Thus, this study is aimed to examine the impacts of the China-Africa trade and Chinese foreign direct investment (FDI) on the growth of...

The algorithm for optimization of a credit portfolio has not been fully demonstrated. This paper fills the gap in the literature by presenting a general approach for optimizing a credit portfolio by minimizing the default risk of the entire portfolio. Default risk is measured with quadratic...

Financing sources for urban construction have garnered significant attention globally. Among various financing methods, the urban construction investment bond (UCIB) is unique to China. The UCIB credit spread, which represents the compensation for credit risk, has become a focal point for...

Full electronic automation in stock exchanges has recently become popular, generating high-frequency intraday data and motivating the development of near real-time price forecasting methods. Machine learning algorithms are widely applied to mid-price stock predictions. Processing raw data as...
