This paper develops a two-sector general equilibrium model in which firms in the primary economy have to create workplaces prior to production and product market competition. For this, we introduce the endogenous sunk cost approach with two-stage decisions of firms from IO in the macro-labor...

Substitution policies are strategies sometimes chosen in Sub-Saharan Africa for curtailing the shortage of health professionals especially caused by the outflow of medical personnel. The aim of our contribution is to propose a way to assess the merits and drawbacks of substitution policies by...

Einfache Lehrbuchmodelle liefern widersprüchliche Aussagen zu den Wirkungen eines arbeitssparenden technischen Fortschritts auf die Löhne. Ein Modell der offenen Volkswirtschaft mit zwei Diversifizierungskegeln zeigt verschiedene Möglichkeiten auf, wie der arbeitssparende technische...

This paper analyzes how the qualitative change in human labor occurs in mutual dependence with the advancement of the epistemic base of technology. Historically, a recurrent pattern can be identified: humans learned to successively transfer labor qualities to machines. The subsequent release of...

Die wissenschaftlichen Diskurse zur ökologischen Tragfähigkeit der gegenwärtigen Wirtschaftsweise und zur Modernisierung von Arbeit verlaufen weitgehend „autonom“. Diesen Schluß legt die Sichtung vorliegender Literatur zum Verhältnis von neuen Arbeitsformen und ökologischem Handeln...

We demonstrate the possibility of shake-out of firms and emergence of inter-firmheterogeneity along the (socially optimal) dynamic equilibrium path of a competitive industry with freeentry and exit, even when there is no uncertainty and all firms are ex ante identical with perfectforesight....

This positional contribution has a twofold aim: the first is to explore the recent empirical literature developed around the issue of how the adoption of new technologies within the firm has changed the skill requirements of occupations; the second is to conjecture on the relationship, and on...

This paper argues that endogenous restructuring processes within firms towards productivityenhancing human resource activities, triggered by advances in information and communication technologies (ICT) and rising supply of educated workers, are typically associated with higher demand for...

I study a model where Information Technology, while typically increasing overall inequality, is likely to harm some people at intermediate and high levels of the distribution of income but to benefit people at the bottom. Within a given occupation it may harm some workers while benefitting...

Two innovations in the last century have changed dramatically the cost of communicating and transmitting information: The first is the widespread adoption of telephony; the second is the internet. We study the implications of these changes in ICT for urban structure. We find robust evidence that...
