In the standard Harris-Todaro framework, migration flows arise as disequilibrium driven movements of the population. It is the purpose of this research to modify the simple dualistic model in order to account for the existence of permanent migrants, i.e., of individuals who work in another...

Purpose – The purpose of this paper is to analyse the labor market outcome when there are two unions in the industry, representing heterogeneous workers – substitutes or complements in production – and using wage strategies, in the presence of minimum wage regulation....

This paper addresses two questions. First, what are the key factors that affect a consumer's lifetime budget constraint and how do they evolve over the lifecycle? Second, how do consumers respond to changes in these factors? We examine the permanent income hypothesis and the Keynesian...

Purpose – Aims to analyse the labour market outcome when there are two unions in the industry, representing heterogeneous workers – imperfect substitutes in production. Design/methodology/approach – Competition between union policies are viewed in terms of both employment and wage...

Purpose – The purpose of this paper is to suggest possible extensions of the baseline Rubinstein sequential bargaining structure – applied to the negotiation of stationary infinitely termed contracts – that incorporate a direct reference to the “ideal” utilities of the players. This is...

This research explores the integration of foreign workers in the Portuguese labor market. It develops two subjects: on the one hand, the position of foreign work in the general employment pattern. On the other, the impact of foreigners on the sector wage-skill schedule, i.e., on log earnings...

This research states the stylised n players’ splitting problem as a mathematical programme, relying on definitions of the values of the game and problem stationarity to generate tractable reduced forms, and derives the known solutions after pertaining first-order conditions. Boundary...

This research contrasts three econometric alternatives for stochastic efficiency frontier analysis: order – inter-quantile – and inverse order regression under the assumption of truncated error term distribution, and replicated moment estimation. The demonstration departs from a simple...

This note develops the solutions of the static portfolio optimization problem in explicit matrix form. Three cases are contemplated and connected, with the derivation of relevant corner solutions: the unconstrained problem in the presence of risky assets only, the constrained one, and the...
