The telegraph process {X(t), t0}, is supposed to be observed at n+1 equidistant time points t_i=i Delta_n,i=0,1,... , n. The unknown value of lambda, the underlying rate of the Poisson process, is a parameter to be estimated. The asymptotic framework considered is the following: Delta_n - 0, n...

Gini and concentration indexes are well known useful tools in analysing redistribution and re-ranking effects of taxes with respect to a population of income earners. Aronson, Johnson and Lambert (1994), Urban and Lambert (2008) decompose Gini and re-ranking indices to analyse potential...

In Chapter 17 of the General Theory (henceforth GT) Keynes tries to generalize the standard GT model, which can be found expounded in the preceding sixteen Chapters of his well-known book, by developing an “extended” model of portfolio choice and capital-asset pricing based on a newly...

Usually, in the Theory of Optimal Experimental Design the model is assumed to be known at the design stage. In practice, however, more competing models may be plausible for the same data. Thus, a possibility is to find an optimal design which take both model discrimination and parameter...

The jointly use of two latent factors methods is proposed to assess a measurement instrument for underlying phenomena. In particular the decay status of valuable Italian buildings is quantified on the basis of a wide set of observed categorical variables. At the purpose, Rasch analysis is used...

This paper studies the impact of endogenous population change on economic growth, analyzing the simplest optimal endogenous growth model, an AK type model, driven by human capital accumulation. We show that in steady state both demographic change and economic growth are constant, but the rate of...

In his economic writings Jevons insists on the allegedly fundamental role played by the so-called "laws of supply and demand" in his theory of exchange; yet no demand-and-supply analysis is actually employed in deriving such theory, as developed in Chapter 4 of The Theory of Political Economy...

In this paper we examine maximum likelihood estimation procedures in multilevel models for two level nesting structures. Usually, for fixed effects and variance components estimation, level-one error terms and random effects are assumed to be normally distributed. Nevertheless, in some...

In a globalised world, where factors of production are increasingly mobile, the process of domestic accumulation of HC can be affected in several ways through migration and capital inflows. In addition, endowment of skilled labour and foreign direct investments(FDI) may reinforce each other...

The analysis sets out to clarify whether households’ demand for consumer credit can be adequately explained by models presented in the literature (life-cycle and permanent income) or whether other factors are observable, such as the use of debt to alleviate financial difficulties. With this in...
