Probability generating function (p.g.f.) is a powerful tool to study discrete compound Poisson (DCP) distribution. By applying inverse Fourier transform of p.g.f., it is convenient to numerically calculate probability density and do parameter estimation. As an application to finance and...

Many countries are concerned with the waste-to-energy for economic development and societal welfare. This paper constructs a dynamic game model that, for the first time compares the incentive effects of four common subsidy modes on waste cooking oil supply for biofuel refining and sales of waste...

The relationship among political connections, government subsidies and firm financial performance of wind and solar manufacturing companies is analyzed based on panel data model. The results illustrate that government subsidies, in long and short-terms, have significant positive effects on the...
