In developing their equilibrium theories over the decade 1871-1881, Jevons (1871), Walras (1874-7), and Edgeworth (1881) made use of some version of a Law, called Law of Indifference by Jevons and Edgeworth and often referred to as the Law of One Price in connection with Walrasian economics. In...

Poverty is a multidimensional, fuzzy and complex phenomenon that cannot be faithfully represented by mono-dimensional monetary indicators. In the last years, much research has been devoted to tackle poverty fuzziness, while less attention has been paid to poverty complexity. In this paper, we...

We address a major discrepancy in matching methods for causal inference in observational data. Since these data are typically plentiful, the goal of matching is to reduce bias and only secondarily to keep variance low. However, most matching methods seem designed for the opposite problem,...

We analyze the opinions regarding tax evasion using a sample of micro-data representative of the Italian population. The analysis of determinants of seriousness and size perceptions of tax evasion suggests that age, education, income, area of residence and occupation are all relevant variables....

In this paper we analyze a simple two-sided adverse selection model with one principal and one agent. They are both risk neutral and have private information about their type. We also assume that the private information of the principal is correlated with the one of the agent. The main result of...

The paper develops a class of Financial market models with jumps based on a Brownian motion, and inhomogeneous telegraph processes: random motions with alternating velocities. We assume that jumps occur when the velocities are switching. The distribution of such a process is described in detail....

This paper analyses migrants’ financial behaviour and financial services demand and investigates supply policies that banks can adopt in order to satisfy their specific financial needs. On the demand side we draw a theoretical framework about migrants’ life cycle and financial needs to...

We study the properties of multifunction operators that are contractive in the Covier-Nadler sense. In this situation, such operators $T$ possess fixed points satisying the relation $x \in Tx$. We introduce an iterative method involving projections that guarantees convergence from any starting...

The LASSO is a widely used statistical methodology for simultaneous estimation and variable selection. In the last years, many authors analyzed this technique from a theoretical and applied point of view. We introduce and study the adaptive LASSO problem for discretely observed ergodic diffusion...

In this paper we propose the use of $\phi$-divergences as test statistics to verify simple hypotheses about a one-dimensional parametric diffusion process $\de X_t = b(X_t, \theta)\de t + \sigma(X_t, \theta)\de W_t$, from discrete observations $\{X_{t_i}, i=0, \ldots, n\}$ with $t_i =...
