Electricity sector reform in developing countries: an econometric assessment of the effects of privatization,competition and regulation

Electricity sectors in both developed and developing countries have been subject to restructuring to introduce private capital and increase competition. Although the effects of such reforms in a number of the developed economies are now well documented, the experience of developing countries is much less well researched. This paper provides an econometric assessment of the effects of privatization, competition and regulation on the performance of the electricity generation industry using panel data for 36 developing and transitional countries, over the period 1985–2003. The study identifies the impact of these reforms on generating capacity, electricity generated, labor productivity in the generating sector and capacity utilization. The main conclusions are that on their own privatization and regulation (PR) do not lead to obvious gains in economic performance, though there are some positive interaction effects. By contrast, introducing competition does seem to be effective in stimulating performance improvements.      

Using Causal Mapping with Group Support Systems to Elicit an Understanding of Failure in Complex Projects: Some Implications for Organizational Research

This paper reflects upon the use of causal mapping supported by a Group Support System (GSS) in a particular legal setting. The mapping method and GSS tool was used for the forensic analysis of eight major engineering and construction projects where the contractor intended to claim significant compensation (typically in excess of $20m). Necessarily detailed records were kept of every aspect of the analyses and processes adopted. This paper is an examination and reflection upon analysis of these records, with particular attention to the process. The task of capturing the way in which participants (witnesses) in a project ‘make sense’ of a cost and time overrun is an important aspect of forensic analysis as they have an experience based perspective, that has often involved dealing with high levels of complexity as projects move from planned order through to what they describe as “absolute chaos”. In addition the requirement to account for, and be held responsible for, behaviors that that may in retrospect be seen as incompetent raises interesting issues in determining the validity of the data capture and analyses. Moreover, participants’ views regarding the complex causality of outcomes, reflected in the causal map, are tested through the use of a simulation model replicating the causal map. The implications of this approach as a research method for undertaking organizational research are thus considered by drawing upon experiences of using the approach to develop the case for litigation in several disruption and delay claims. In particular the paper addresses the issues related to defensiveness of participants, anonymity, accessing multiple perspectives in a group setting, organizational learning and the ‘changing of mind’ of participants, and developing an organizational memory.

Evaluating the effectiveness of labor market interventions on reducing the impacts of the COVID-19 pandemic

This paper evaluates whether different labor market policy interventions taken in response to the COVID-19 pandemic have been effective in reducing its adverse impacts. We construct a database covering 165 countries and 39 labor market interventions grouped into four pillars: stimulating the economy and jobs (pillar 1); supporting enterprises, employment, and incomes (pillar 2); protecting workers (pillar 3); and social dialogue (pillar 4). The results revealed that measures taken under pillars 1, 2, and 3 have reduced the impacts of the pandemic on economic growth; measures under pillar 4 were significantly associated with reducing its impacts on employment and those under pillar 2 with reducing its impacts on working hours.
