Residual momentum strategies earn significant alphas. The common interpretation for this result - that momentum resides in firm-specific returns - is unwarranted: even in the absence of firm-specific momentum, a strategy sorted on residuals is profitable because it is also a bet against betas. A...

Spatial modeling is one of the growing areas of research in economics in recent years. However, these models are not tested enough. Even if tests are performed, they are done in a piece-wise fashion. Another age-long problem in economic modeling is endogeneity of one or more variables....

Indonesia is helming the Group of 20 (G20) presidency for the very first time. A key initiative as announced in the presidential address is the post-pandemic economic recovery. The nation has the largest nominal gross domestic product (GDP) among the 10 nations of Southeast Asia. The research...

The present paper concerns with a Godunov-type method for the isentropic polytropic gas subjected to transverse magnetic field in a variable cross-section duct.Typical Riemann solutions are used to build the numerical flux at cell interface. We mainly address and solve numerically two special...

Turbulent dispersed multiphase systems are of paramount importance in numerous physical applications. In terms of the numerical modeling of such systems, crucial aspects are, among others, the mathematical representation of dispersed particles and the effect of fluid turbulence on those...
