We investigate the suitability of sparse grids for solving high-dimensional option pricing and interest rate models numerically. Starting from the partial differential equation, we try to - at least partially - break the curse of dimensionality through sparse grids which will result from a...

Air pollution is today a serious problem, caused mainly by human activity. Classical methods are not considered able to efficiently model complex phenomena as meteorology and air pollution because, usually, they make approximations or too rigid schematisations. Our purpose is a more flexible...

Affective habituation is well-documented in social sciences: people seem to adapt to many life events, ranging from lottery windfalls to terminal illnesses. We propose a subtle but critical difference: current happiness may depend directly on past happiness. We test our hypothesis running...

We used scanner data to test whether two competitive commodities respond symmetrically by volume to price changes. Our results indicate that consumers of the most expensive good (Coca-Cola) respond quite symmetrically when prices go either up or down. In contrast, consumers of the less expensive...
