Building upon some education studies finding that cooperative behaviour in class yields better achievements among students, this paper presents a simple model showing that free riding incentives lead to an insufficient degree of cooperation between schoolmates, which in turn decreases the...

We examine what determines differences across countries and over time in the distribution of personal incomes in the OECD. We first model the wage determination process and show that unemployment, the labour share, and the wage differential are all functions of labour market institutions. Next...

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...

The telegraph process $X(t)$, $t0$, (Goldstein, 1951) and the geometric telegraph process $S(t) = s_0 \exp\{(\mu -\frac12\sigma^2)t + \sigma X(t)\}$ with $\mu$ a known constant and $\sigma0$ a parameter are supposed to be observed at $n+1$ equidistant time points $t_i=i\Delta_n,i=0,1,\ldots, n$....

In this paper some results on the problem of computing optimal designs for discriminating between rival models are provided. Using T-optimality for two rival models a compound criterion is developed to discriminate between more than two models. Surprising results arise when T-optimal designs are...

In this paper, we develop a general collage coding framework for inverse problems in partial differential equations (PDEs) with boundary conditions. Although a general PDEs inverse problem can be very complicated, via the Generalized Collage Theorem in this paper, many such problems can be...

In this paper we test the empirical evidence of an impact of privatisation on output in the UK , through macroeconomic transmission channels. While most privatisation studies focus on microeconomic shocks, namely at firms' level, we are interested to see whether a large scale privatisation...

The shadow wage is the social opportunity cost of labor. After reviewing earlier theoretical and empirical literature, we define four labor market conditions: fairly socially efficient (FSE), quasi-Keynesian unemployment (QKU), urban labor dualism (ULD) and rural labor dualism (RLD). We offer,...

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,...

The term CRM, Customer Relationship Management, is one of the most used word both in Marketing and IT literature and applications. This term is most of the time used as a replacement of a misleading narrow term: Relationship Management (RM). Operations, Customer Service, Sales, human resources,...
