15161. Diffusion of Digital Mobile Telephony: Are Developing Countries Different?

Abstract:
Factors determining the diffusion of digital mobile telephony across 200 developed and developing countries in the 1990s are studied with the aid of a Gompertz model. The market size and network effects are found to play more important roles in the developing countries; there is also more need for complementing innovations in, for example, financial and payment systems. Even though the developing countries have disadvantages, being late entrants in digital mobile telephony is to their advantage and promotes cross-country convergence. Overall digital technologies are best seen as equalizers, and thus the divide is rather socio-economic or analog than digital.

15162. An Aggregate View of Macroeconomic Shocks in Sub-Saharan Africa: A Comparative Study Using Innovation Accounting

Working Paper

Abstract:
This paper investigates the impacts and responses of macroeconomic shocks in some domestic economies in Sub-Saharan Africa over the period 1961-99; more specifically, it seeks to answer the question of whether there are any systematic differences in the responses of the CFA franc zones and the non-CFA franc zone countries to macroeconomic shocks. Based on the Blanchard-Quah methodology, we identify shocks to the changes in real exchange rate and output using a structural VAR (SVAR) model for these small open economies. Our finding that the real exchange rate innovations in the CFA franc zones are largely independent of domestic variables suggests that external influence is more important in the CFA zones. There is also some evidence that money demand shocks are more significant in the non-CFA franc zone countries.

15163. Conceptual and Measurement Issues in Poverty Analysis

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
The objective of this paper is to review a number of issues related to poverty, while taking stock of the ongoing research. Most of the remaining unresolved issues in poverty analysis are related directly or indirectly to the dynamics of poverty. Before the development community can become more successful in designing and implementing poverty-alleviation strategies, within the context of growth, we need to understand better the conditions under which some households remain permanently (chronically) poor and how others move in and out of poverty. In what follows we review the state of the art under a number of interrelated headings: (1) Chronic vs. transient poverty; (2) Poverty and vulnerability; (3) The determination of the poverty line across time and countries; (4) The quantitative vs. qualitative approach to poverty measurement; and (5) Growth, inequality and poverty.

15164. An Inquiry into Cities and Their Role in Subnational Economic Growth in South Africa

Abstract:
South Africa is characterized by significant inequality in spatial economic activity. Whether future growth and development on a subnational level in South Africa will be such as to reduce this inequality may depend on the economic growth and development of South Africa's largest cities. Our local economic growth empirics show some indications of conditional convergence in output between poorer towns as well as overall between all cities and towns. Between 1990 and 2000 some limited sigma convergence was found but this was driven by declines in the standard deviation of per capita income amongst the poorest quintile of towns. An estimate of conditional beta convergence of 1.2 percent over the period 1990-2000 confirms that overall convergence has been taking place. From an estimation of the determinants of economic growth on a local level, using a dataset on 353 local areas in South Africa between 1990-2000 we found the most significant determinants to be stocks of human capital and distance from harbours and markets. The effect of human capital on economic growth was strongly associated with the presence of large cities, as one would predict from endogenous growth theory.

15165. Return International Migration and Geographical Inequality: The Case of Egypt

Working Paper

Abstract:
This paper explores entrepreneurship amongst return migrants, how their business locations and characteristics differ from other businesses, and the implications for rural urban inequality. First, we examine, amongst returnees, the determinants of investment in a project/enterprise. Second, we study the impact of return migration on the characteristics and nature of non-farm small enterprises using a sample of return migrants and non-migrant owners of enterprises. Our data indicate that although the share of return migrants originating in urban areas is almost equal to those from rural areas, and that migrants tend to return to their origin region, urban areas benefit more than rural areas from international savings. The empirical evidence suggests that overseas savings, and the duration of stay overseas, have positive separate effects on the probability of investing in a project/enterprise amongst returnees. Furthermore, returnees from urban-origin are more likely than rural ones to invest in a non-farm enterprise. The findings also indicate that there is a regional bias in the location of firms and jobs created by returnees compared to non-migrants, in favour of the capital city. Thus, overall, the results support a positive impact of return migration on enterprise investment in urban areas driven by the preference of returnees to invest in urban areas.

15166. Love Thy Neighbour? Evidence from Ethnic Discrimination in Information Sharing within Villages

Author:

Working Paper
Institution:
United Nations University
Abstract:
There is increasing evidence to suggest that a fundamental source of information for farmers on how to access and use new agricultural technologies comes from interacting with neighbours. Economic research on adoption of innovations in a rural context has only partially addressed the issue of how the social structure of a village can affect adoption and the final impact on productivity of farmers. This paper investigates the role of proximity interpreted not only in geographical terms but also along the line of ethnic similarities among neighbours (what we define as 'social proximity'). We use a panel dataset collected in Côte d'Ivoire to define the probability of accessing the knowledge network. The main results indicate that farmers from ethnic minorities are less likely to access, and benefit less from, extension services. But they seem to try to re-equalize their condition by putting more effort than dominant ethnic group neighbours in sharing information among themselves.

15167. Crime, Isolation, and Law Enforcement

Author:

Working Paper

United Nations University
Abstract:
This paper investigates the relationship between criminal activity and geographical isolation. Using data from Madagascar, we show that, after we control for population composition and risk factors, crime increases with distance from urban centers and, with few exceptions, decreases with population density. In Madagascar, crime and insecurity are associated with isolation, not urbanization. This relationship is not driven by placement of law enforcement personnel which is shown to track crime, but fails to reduce feelings of insecurity in the population. Other risk factors have effects similar to those discussed in the literature on developed countries. We find a positive association between crime and the presence of law enforcement personnel, probably due to reporting bias. Law enforcement personnel helps solve crime but appears unable to prevent it.

15168. Urban-Rural Inequality in Living Standards in Africa

Working Paper
Institution:
United Nations University
Abstract:
In this paper we examine the relative importance of rural versus urban areas in terms of monetary poverty and seven other related living standards indicators. We present the levels of urban-rural differences for several African countries for which we have data and find that living standards in rural areas lag far behind those in urban areas. Then we examine the relative and absolute rates of change for urban and rural areas and find no overall evidence of declining differences in the gaps between urban and rural living standards. Finally, we conduct urban-rural decompositions of inequality, examining the within versus between (urban and rural) group inequality for asset inequality, education inequality, and health (height) inequality.

15169. Economic Growth, Income Distribution and Poverty: Time-series and Cross-country Evidence from the CFA-zone Countries of sub-Saharan Africa

Abstract:
The causes of the slow growth of CFA countries are investigated. There is little difference in this respect between the CFA and other sub-Saharan African countries. Since 1970, GDP growth in the CFA countries has shown no significant trend but one or two medium-term fluctuations (positive in 1979-83 and negative in 1989-93). Internationally, the income share of the poorest 20 per cent of the population of any country has improved most in poor countries, and there is no evidence that this does not apply to CFA countries also.

Abstract:
The West African Economic and Monetary Union (UEMOA) has a history of monetary stability and low inflation. Nevertheless, there is substantial variation in relative prices within some UEMOA countries, in particular in the price of food relative to other elements of the retail price index (IHPC). Using monthly time-series data for cities within the region, we analyze the impact of changes in monetary policy instruments on the relative prices of components of the IHPC. We are then able to explore how the burden of monetary policy innovations is likely to be shared between the rich and poor.
