We propose a novel modification to the popular principal component analysis (PCA) by scaling each predictor with its predictive slope on the target to be forecasted. Unlike the PCA that maximizes the common variation of predictors, our scaled PCA, sPCA, puts more weights on those predictors that...

The fund size is highly persistent and correlated with risk factor loadings. Hence, it is unrealistic to assume constant diseconomies of scale over a long time. The traditional two-step method underestimates the uncertainty of diseconomies of scale. We propose a one-step procedure with a random...

Economic growth is frequently explained by an increase in the quantity of production. However, economic growth is an increase in the productive capacity of an economy and it is explained by an outward shift of production possibility frontier. The aim of this study is to measure economic growth...
