This is a short survey on consumption theory. Consumption is important to both fluctuation and growth. In addition, consumption introduces some important issues involving financial markets and portfolio decisions. We will describe consumption decisions in a dynamic context. Uncertainty about...

The analysis and measurement of poverty is a crucial and unsolved issue in the field of social science. This work aims to measure poverty as a multidimensional notion using a new composite indicator. However, subjective choices as different weighting schemes on the indicator's construction could...

Nel presente articolo è proposta un'estensione della tecnica degli alberi bi/tri-nomiali, largamente usata per la valutazione di titoli derivati, ad una tecnica basata sulla costruzione di alberi N-nomiali, con N intero arbitrario. Il vantaggio di tale tecnica consiste essenzialmente in 1)...

Coordination failures are very important in imperfect markets, because of related concept of multiple equilibria. This article attempts to explore this topic using tools to overcome the limitations of traditional analytical apparatus, which imposes stringent conditions about functions and...

L'economia politica è, tra le scienze umane, quella che maggiormente sperimenta l'attrazione verso i metodi quantitativi e in particolare verso la matematica e la statistica. Recentemente questa attrazione si è fatta ancor più forte che in passato, al punto che non è raro trovare, tra gli...

Italian Abstract: Questo lavoro si propone il compito di individuare un approccio alternativo (in termini di algoritmo matematico) in grado di determinare con velocità (i.e. di convergere nel giro di poche iterazioni) il valore della volatilità implicita delle opzioni. Tale valore è di...

The estimation method of Two Stage Least Squares (2SLS) with Principal Components (2SPC) is applied to a medium-sized nonlinear econometric model of the Italian Economy.

Problems related to deterministic solution of nonlinear econometric models are well known in the literature. The use of mean (average) stochastic simulation results has been usually proposed to solve the problem of bias. This raises however other types of problems, like possible non-coherent...

Country risk and sovereign risk are two of the most important topics in risk management. The first part of this work introduces these concepts and shows the differences between them. The following chapters fit linear and ordinal regression models to a data-set with more than 100 countries, where...

In this paper we address the issue of forecasting Value–at–Risk (VaR) using different volatility measures: realized volatility, bipower realized volatility, two scales realized volatility, realized kernel as well as the daily range. We propose a dynamic model with a flexible trend...
