Attempts can be found in the DEA literature to identify returns to scale at efficient interior points of the production possibility set on the basis of returns to scale at points of the corresponding reference sets. However, an opposite approach is put forward in this paper, advocating that...

Koopmans gyakorlati problémák megoldása során szerzett tapasztalatait általánosítva fogott hozzá a lineáris tevékenységelemzési modell kidolgozásához. Meglepődve tapasztalta, hogy a korabeli közgazdaságtan nem rendelkezett egységes, kellően egzakt termeléselmélettel és...

Using a model of O-ring production function, the paper demonstrates how certain communities can get caught in a low-literacy trap in which each individual finds it not worthwhile investing in higher skills because others are not high-skilled. The model sheds light on educational policy. It is...

Cobb Douglas production function parameters are not identified from cross-section variation when inputs are perfectly flexible and chosen optimally, and input prices are common to all firms. We consider the role of adjustment costs for inputs in identifying these parameters in this context. The...

This paper considers a model of economic network characterized by an endogenous architecture and frictions in the relations among agents as described in Bala and Goyal (2000). We propose a similar network model with the difference that frictions in the relations among agents are endogenous....

This study analyzes the relationship between the three main enterprise systems (Enterprise Resource Planning (ERP), Supply Chain Management (SCM), Customer Relationship Management (CRM)) and labor productivity. It reveals the performance gains due to different combinations of these systems. It...

This paper examines the relationship between the use of advanced technologies such as ICT, and outcomes such as productivity, the skill mix of the workforce and wages using micro data for the U.S. and Germany. We find support to the idea that U.S. businesses engage in experimentation in a...

This paper shows the strategic aspects of international outsourcing in an oligopolistic market, if outsourcing is attractive because of fixed cost savings. We show that outsourcing decisions are strategic substitutes. Furthermore, we demonstrate that due to decreasing individual output,...

We propose a new method for estimating the power-law exponent of a firm size variable, such as annual sales. Our focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. As is well known, a firm size variable follows a power-law distribution...

This paper studies organizations with autocratic decisionmaking, i.e., where superiors make the decisions and subordinates either defy or submit to the authority. Superiors differ in the degree to which they fear defiance. The superiors who need obedience most face a fundamental credibility...
