- The sustainability of the construction industry in sub-saharan Africa: some new evidence from recent dataPublication . Lopes, Jorge; Oliveira, Rui; Abreu, Maria IsabelThe relationship between a country’s level of construction activity and its stage of economic development has been the subject of study at the macroeconomic level for a number of years. The dominant paradigm in the field is that the construction industry follows an inverted U shaped development pattern i.e. the share of construction in national economy first increases in the early stages of development and ultimately decline in the latest stages of development. An examination of construction indicators in two categories of countries in Sub-Saharan Africa is made and the link between construction investment and the economic and social targets of the sustainable development goals is considered.
- Methodologies for estimating the built environment stock: an overviewPublication . Lopes, Jorge; Oliveira, Rui; Abreu, Maria IsabelThe role of the construction sector in the process of economic growth and development is well recognized in the literature. However, in the most advanced industrial economies, as well as emerging economies, the construction industry is no longer focused on providing a single service, i.e., a building or physical infrastructure, but on a variety of services and improvement of human and natural environments. Built capital stock is a major component of any country’s produced fixed capital as designated in the System of National Accounts (SNA) of the United Nations. According to several writers, the knowledge of reliable data of building and other construction assets of a specific country or region is a crucial element for the long-term management of these assets. This paper presents an overview of the Perpetual Inventory Method (PIM) used for estimating capital stock and some methodologic issues regarding the measures of construction investment and of built capital stock. Additionally, based on the results of an earlier work, estimates of the Cape Verde’s built capital stock for the year 2014 are presented. The level of the of the built capital stock of a specific country and its impact on the development pattern of the construction industry is a suggestion for further studies.
- The construction sector and economic growth in sub-Saharan Africa (revisited)Publication . Lopes, Jorge; Oliveira, Rui; Abreu, Maria IsabelThe relationship between a country’s level of construction activity and its stage of economic development has been the subject of study at the macroeconomic level for the last forty years or so. This study follows an earlier research that investigated the relationship between investment in construction and economic development in Sub-saharan Africa (SSA), and found that the share of construction in national economy follows an inverted U-shaped pattern of development. That is, it firstly increases in the early stages of development and ultimately tend to decline in the latest stages of economic development. The research is based on data acquired on 22 of the countries in SSA over the period 1990-2017 and the sample is split into two groups according to the proportion of the construction sector in total value added in the period 1990-1999. The results of the analysis of the development pattern of the construction industry in the two categories of countries tend to corroborate the results of the earlier work in what regards the evolutionary pattern of the middle-income economies in SSA.
