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...

This paper analyses the distribution of the classical t-ratio statistic from distributions with no finite moments and shows how classical testing is affected. Some surprising results are obtained in terms of bimodality vs. the usual unimodality of the standard studentized t-distribution...

A new procedure to identify grading practice is proposed. In our approach, grading practice are given in terms of a categorical variable whilst usually in the literature, coefficients of the regression line which models school grades as a function of students' achievement, are taken as...

Partial Order Theory has been recently more and more employed in applied science to overcome the intrinsic disadvantage hidden in linear ranking, if a multiple indicator system is available. Despite its numerous positive features, there are many practical cases where the interpretation of the...

Designs are found for discriminating between two non-Normal models in the presence of prior information. The KL-optimality criterion, where the true model is assumed to be completely known, is extended to a criterion where prior distributions of the parameters and a prior probability of each...

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...

This paper presents a simple principal-supervisor-agent model of the investment game between a supranational player (the principal), such as the European Commission, a regional government (the supervisor), and a private firm (the executing agency) . The EC is a benevolent social welfare...

We deal with a planar random flight {(X (t), Y (t)), 0 t ? T } observed at n + 1 equidistant times ti = i?n , i = 0, 1, ..., n. The aim of this paper is to estimate the unknown value of the parameter ?, the underlying rate of the Poisson process. The planar random flights are not markovian,...

This paper reconsiders the effects of population growth on per-capita income growth within a Romerian (1990)-type endogenous growth model with human capital accumulation. One important novelty of our contribution is that in the human capital accumulation equation we explicitly consider the...
