Although activation services such as monitoring, training, or job subsidies have been shown to increase exits from unemployment, there is little comprehensive evidence about the effects of activation during recessions. Here we evaluate a large activation programme introduced in Portugal in 2012,...

PISA uses a complex sampling procedure based on stratification variables chosen by the participating countries’ authorities. In this paper we analyse the representativeness of the samples used in terms of the distribution of students per grade and track of studies for Portugal. For the three...

We show that monetary trading is simple, self-enforcing, symmetric, and irreducible in a natural framework. Furthermore, we will show that the utility for each economic agent is at least as big under the monetary system as under any other simple, self-enforcing, symmetric, and irreducible...

Positive Organizational Behavior (POB) is taking its momentum in management studies, but it is far from its fullest potential as it is not yet developing integrative comprehensive explanatory models of organizational behavior. This article discusses the biased character of POB revealed in its...

The prediction of asymmetric equilibria with Stackelberg outcomes is clearly the most frequent result in the endogenous timing literature. Several experiments have tried to validate this prediction empirically, but failed to find support for it. By contrast, the experiments find that...

We analyse the effects of universal service obligations, such as uniform pricing, price caps and unbundling, on allocations in markets newly opened to competition, e.g. telecommunications. If uniform pricing is imposed not only on incumbents but also on entrants, entry may not result in...

This paper argues that the apparent contradiction in current conceptualizations of time in organizations (e.g., Chronos vs. Kairos) is only apparent, and that a synthesis between these opposing poles is both possible and desirable. We propose improvisation (where time to plan converges with time...

The topic of spirituality is gaining an increasing visibility in organization studies. It is our contention that every theory of organization is a theory of organizational spirituality. Based on Barley and Kundas 1992 Administrative Science Quarterly article, we discuss the evolution of...

We draw on evidence scattered across thick descriptions of organizations to outline an alternative model of routine. Instead of defining routine as a process of compliance with prescribed rules and procedures we define it as a process of deviation from the prescribed elements of organizations,...
