This paper describes a variety of approaches used to assess the efficiency of a sample of major insurance companies in Angola between 2003 and 2012. Starting out with the bootstrapping technique, several data envelopment analysis (DEA) estimates were generated, allowing the use of confidence intervals and bias correction in central estimates to test for significant differences in efficiency levels and input‐decreasing/output‐increasing potentials. Previous studies have focused on the measurement and explanation of the factors affecting the performance rather than the prediction. The use of neural networks combined with DEA results as part of an attempt to produce a model for insurance companies’ performance with effective predictive ability is investigated. The findings indicate that older insurance companies with Portuguese origin tend to be more efficient. Results also suggest that opportunities for accommodating future demand appear to be scarce.  相似文献

This article analyses the level of competition in Angola’s banking industry using the Panzar–Rosse model with data from 2005 to 2014. Competition is a vital aspect of the banking market and therefore it is central to policy-making. The results reveal that Angola banking competition is monopolist and therefore lower competition is found in Angola banks. Policy implication is derived.  相似文献

Angola's four decades of civil war continue to have a profound effect on the country's recovery and development. While the end to the war in 2002 and the subsequent extraction of natural resources has fueled the country's economic recovery for a minority, for the majority recovery depends less on natural resource extraction than it does on acquiring and maintaining secure access to land and property upon which viable livelihoods can be rebuilt. However the current large scale evictions in urban and peri-urban areas of the country and the resulting acute tenure insecurity is significantly worrying, and is the single most acute land rights, land policy, and political problem in the country. Aspects of the country's constitution and the development of the postwar land law facilitate eviction, and an important opportunity to upgrade postwar informal land rights has been missed. Land and property rights problems have played a significant role in the country's armed conflicts and social problems, and current trends are constructing a difficult future.  相似文献

This article analyses the relationship between investment and savings for Angola using the Feldstein–Horioka puzzle, with monthly data from January 2000 to December 2013. Integer and fractional integration and cointegration techniques are employed to investigate the relationship between investment and savings. Several regression specifications are employed, concluding that the Feldstein–Horioka puzzle is not validated for the Angolan economy. Policy implications are derived.  相似文献

The Okavango catchment is a hot spot of accelerating land use change. In particular, climate predictions, demographic developments and a growing utilization of ecosystem services and functions are expected to increase pressure on resources and land. Land use conflicts, the sustenance of precarious livelihoods, deforestation of woodland savannahs, upstream–downstream water issues and human–wildlife conflicts are among the processes that are characteristic of policy and management challenges in the region. In the Eastern and Western Kavango regions of Namibia and the Cuando-Cubango province of Angola, a unique cross-border situation exists that allows assessing how the combination of local traditions, regional land management and national policies determines spatial patterns of land use and land cover transformation processes.To map major land use types and change processes we used a set of multi-temporal Landsat-5 TM and Landsat-7 ETM+ data sets, support vector machine (SVM) classification and iterative spectral mixture analysis (ISMA) on images covering the period from 1990 to 2010. Integrating satellite imagery with literature reviews, interviews, census and household survey data, we assessed the contrasting development of resource utilization on both sides of the Okavango River. We investigated if and how policies and regulations at different levels drive land use decisions, and how these decisions manifest spatially.We found a strong and interconnected urban growth on both sides of the river. The area around Rundu has constantly been evolving to become Namibia's second largest city, also functioning as a hub of development and transborder commerce with opposing Calai. This trend was found to affect adjacent settlement areas and cause widespread conversion of woodland savannahs to agricultural land or their utilization for timber extraction. The conversion of woodland savannah to arable land was by far the dominant land use change process on both sides of the river, with a total conversion area of 460 km2 (Namibia) and 293 km2 (Angola) observed during the observation period. Strong spatial change gradients occurred in relation to determining factors, such as accessibility, proximity to water, urban centres, etc., while relations to settlements where less obvious. Assessing results by country illustrated the difference in land use intensity and resource consumption between Angola and Namibia, which relate directly to historical developments, with a long period of stability in Namibia standing opposed to the recent and ongoing recovery from civil war in Angola. These are added to by statutory and traditional policy frameworks, the national endowment with natural capital (e.g. oil, uranium, diamonds, zinc) and the integration into global markets, which strongly affects national economies of both countries at large.Underlying land use decisions were found to be largely driven by individualized perspectives on growth ideologies, consumerism and wealth-aspirations connected to globalization processes. However, at present the result of these perspectives is still mainly a small-structured conversion to rainfed agriculture as a component of subsistence strategies of local livelihoods, and thus stands opposed to other regions of the world, where change processes are much more driven by large companies or follow national regulations and result in more intensive uses.  相似文献

The purpose of this paper is to examine the degree of persistence in five inflation indicators for Angola, and to identify the implications for decision making. Our results suggest that when structural breaks are accounted for, all five inflation indicators are stationary. Second, our findings suggest that persistence is not too high. Moreover, the degree of persistence is similar among the five inflation indicators and throughout the sample period. Finally, our results also show that extracting the most volatile components of the headline inflation indicator does not generate a new inflation indicator that is less volatile and more persistent than the original. These results have important policy implications as the National Bank of Angola is preparing to change its monetary policy focus to a more inflation‐targeting regime.  相似文献

This paper presents an efficiency assessment of the Angolan banks using Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS). TOPSIS is a multi‐criteria decision‐making technique similar to data envelopment analysis, which ranks a finite set of units based on the minimisation of distance from an ideal point and the maximisation of distance from an anti‐ideal point. In this research, TOPSIS is used first in a two‐stage approach to assess the relative efficiency of Angolan banks using the most frequent indicators adopted by the literature. Then, in the second stage, neural networks are combined with TOPSIS results as part of an attempt to produce a model for banking performance with effective predictive ability. The results reveal that variables related to cost structure have a prominent negative impact on efficiency. Findings also indicate that the Angolan banking market would benefit from higher level of competition between institutions.  相似文献

The Aldeia Nova Project in Angola is aimed at demobilising ex-combatants to rural areas and settling them in modern agricultural communities. The first settlers arrived in the Waku-Kungu Valley in 2005 and now 600 families are using modern agricultural technology to produce milk, eggs and vegetables, which are marketed in the urban centres. The Project has enhanced the families' livelihoods and provided employment to hundreds of other Angolans, and the entire region has been revitalised, with a large number of new families arriving to enjoy the benefits of the improved local economy. This paper presents the concept of the Project, describes its evolution and discusses its strengths and weaknesses. It concludes that the Project has had benefits beyond its measureable economic impact and that Aldeia Nova's original and ambitious goals are not beyond the reach of the Angolan people.  相似文献

This paper analyses technical efficiency in Angolan banks from 2005 to 2010 with an innovative production frontier model, the model. The intermediate approach is adopted. It is observed that the efficiency increases over the observation period, according to the international experience, market share and local markets. Policy implications indicate that competition and governance should be promoted in order to increase efficiency.  相似文献
