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...

The discounting of future felicity flows transposes to the intertemporal optimization context the assumption of interest-bearing wealth or savings. The validity of the hypothesis has been challenged by several empirical (ir)regularities and by the theoretical implications for human decision...

On Simple Conditions for Mixed Equilibria in Dualistic Models. Part I: Degree of Mobility

This research extends simple two-sector models in order to inquire the impact of the extent of coverage or enforcement of minimum wage legislation in one of the sectors on the equilibrium outcome. Two versions of institutional wage avoidance are presented. They may be seen as representing...

The paper contrasts the pattern of returns to human capital in different economic sectors. As job mobility, especially across sectors, is limited, it is argued that coefficients of experience in earnings regressions may capture or be interpreted as the growth rate – net of depreciation – of...

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 research states the stylised n (more than two) 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 according to the properties of pertaining...

This note suggests variations to the baseline Nash cooperative solution that take into account the Kalai-Smorodinsky critique. One the one hand, a CES form of the maximand is proven to accommodate both the generalized two-person Nash and the Kalai-Smorodinsky - as other proportional - solutions...

This paper discusses the sensitivity of the labor market outcome in the standard bargaining paradigms - monopoly union and efficient bargaining - to the existence of a budget constraint pending on the financing of the unemployment benefit. Consequences of how the unions value members and...
