To investigate and illustrate the idea of using a cybernetic modelling technique for the diagnosis and design of virtual enterprises (VEs).

Abstract

Purpose

To investigate and illustrate the idea of using a cybernetic modelling technique for the diagnosis and design of virtual enterprises (VEs).

Design/methodology/approach

The proposed framework is based on the VSM principles and its equivalent problem structuring methodology schema for the design of the information and communication systems together with the coordination structure necessary for a VE to become more efficient and flexible.

Findings

We have investigated the role of VEs as a new organizational structure viewed from the perspective of cybernetics. In particular, the systemic approach followed was used to formulate a generic four‐step architecture for the effective diagnosis and design of VEs, based on the theoretical principles of Stafford Beer's viable systems model (VSM).

Research limitations/implications

There is considerable scope for further investigation on organizational structures and implications in the creation of effective VEs for many more management field locations, both within the industrial and in other areas of the business world.

Practical implications

A generic and easily applicable conceptual framework for managers who wish to commit themselves to the necessary re‐shaping of the organization they are running, forming new organizational structures based on autonomy and flexibility rather than hierarchy and rigidness.

Originality/value

This paper fulfils an identified need to oversee the full spectrum of VEs and offers a comprehensive and unambiguously defined conceptual framework for their diagnosis and design based on the principles of Beer's VSM.

Abstract

Purpose

This paper presents an integrated overview of the empirical literature on the impact of all forms of unconventional monetary policy on macroeconomic variables and on markets.

Design/methodology/approach

This survey covers the findings concerning portfolio rebalancing, signaling, liquidity, bank lending and confidence channels.

Findings

The positive effect of QE announcements on stock and bond prices seems to be unified across studies. A contagion effect from US QE to other emerging markets is identified, while currency devaluation is present in most cases for the country that its central bank adopted such policies. Moreover, impacts of non-conventional practices on GDP, inflation and unemployment are examined. The studies presenting weak instead of strong positive effects on inflation are more, and these studies, also, present weak positive effects on GDP growth.

Originality/value

Based on the large body of research on non-conventional action taking, this is the first survey including effects of each country that adopted quantitative easing (QE) measures and that provides results from every methodology employed in order to estimate unconventional practices' impacts.
