Giuseppe Orlando is Full Professor at the Department of Economics at the HSE University of Saint Petersburg. Giuseppe does research in Economics, Finance, Actuarial Science and Econometrics. His current projects are on Risk, Business Cycles Modeling, Banking Clearing Problems and Interest Rates Forecasting. In finance, Giuseppe Orlando developed his version of the CIR model so-called CIR# to forecast interest rates. The same model has been fruitfully employed in the forecasting of highly periodic but disrupted by the pandemic time series such as those of tourism. In economics, he developed a deterministic chaotic model of the business cycle within the Kaldor-Kalecki framework. Then Giuseppe Orlando investigated determinism and randomness in the real-world and he found that a deterministic model could be toe-to-toe with a stochastic model.
