Infrastructure regulation and poverty reduction in developing countries: a review of the evidence and a research agenda

Poverty reduction is a primary goal of development policy. In large parts of the World people have to live on meagre incomes and have limited access to infrastructure services, such as mains water, safe sanitation, mains power supplies, maintained roads and telephones. In response, more and more infrastructure provision has been opened up to private investment over the last two decades and regulatory institutions have been introduced to protect the public interest in the absence of state ownership. In this paper the role of infrastructure regulation in poverty reduction is investigated drawing on the published evidence. The conclusion is that the evidence is both patchy and sometimes contradictory. There is mixed knowledge regarding the extent to which regulators address poverty issues and about the results of regulatory decisions. The paper concludes by proposing a future research agenda aimed at improving our understanding of the ways in which infrastructure regulation impacts on poverty, with the objective of improving actual regulatory policy in developing economies

Creating the Conditions for International Business Expansion: The Impact of Regulation on Economic Growth in Developing Countries - A Cross-Country Analysis

The role of an effective regulatory regime in promoting economic growth and development and therefore international business has generated considerable interest among researchers and practitioners in recent years. In particular, building effective regulatory structures in developing countries is not simply an issue of the technical design of the most appropriate regulatory instruments, it is also concerned with the quality of supporting regulatory institutions and capacity. Many of the institutions that support markets are publicly provided and the effectiveness of these regulatory institutions can be expected to be an important determinant of how well markets function. This paper explores the role of regulation in affecting economic outcomes using an econometric model of the impact of regulatory governance. More precisely, it assesses through econometric modelling the impact of variations in the quality of regulatory governance on economic growth. Proxies for regulatory quality are included as determinants of economic growth. The results based on two different techniques of estimation suggest a strong causal link between regulatory quality and economic performance. The results confirm that "good" regulation is associated with higher economic growth, which in turn is conducive to the expansion of international business.economic growth, regulation, governance, institutions, economic performance, International Development, C23, I18, L33, L51, L98, O38, O50,

Assessing the Effects of Privatisation, Competition and Regulation on Economic Performance: The Case of Electricity Sector Reform

Over the last two decades electricity sectors in both developed and developing countries have been subject to restructuring to introduce private capital and increase competition. This has been accompanied by the introduction of new regulatory regimes. Although the effects of such reforms in a number of the developed economies are now well documented, apart from a few case studies the experience of developing countries is much less well researched. This is important because privatisation, competition and the reform of state regulation are key themes of donor aid programmes, notably those of the World Bank. This paper provides an econometric assessment of the effects of privatisation, competition and regulation on the performance of the electricity generation industry using panel data for 36 developing and transitional countries, over the period 1985 to 2003. The study identifies the impact of these reforms on generating capacity, electricity generated, labour productivity in the generating sector and capacity utilisation. The main conclusions are that on their own privatisation and regulation 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.Privatisation, competition, regulation, developing economies, electricity sector.

On the Age of the Widest Very Low Mass Binary

We have recently identified the widest very low-mass binary (2M0126AB), consisting of an M6.5V and an M8V dwarf with a separation of ~5100 AU, which is twice as large as that of the second widest known system and an order of magnitude larger than those of all other previously known wide very low-mass binaries. If this binary belongs to the field population, its constituents would have masses of ~0.09 Msun, at the lower end of the stellar regime. However, in the discovery paper we pointed out that its proper motion and position in the sky are both consistent with being a member of the young (30 Myr) Tucana/Horologium association, raising the possibility that the binary is a pair of ~0.02 Msun brown dwarfs. We obtained optical spectroscopy at the Gemini South Observatory in order to constrain the age of the pair and clarify its nature. The absence of lithium absorption at 671 nm, modest Halpha emission, and the strength of the gravity-sensitive Na doublet at 818 nm all point toward an age of at least 200 Myr, ruling out the possibility that the binary is a member of Tucana/Horologium. We further estimate that the binary is younger than 2 Gyr based on its expected lifetime in the galactic disk.Comment: accepted for publication in The Astrophysical Journa

The structural architecture of seismogenic faults, Sierra Nevada, California; implications for earthquake rupture processes

Earthquake ruptures along tectonically active faults nucleate predominantly at depths of 5 to 12km in the crust, so the portions of faults that slip in these events cannot be directly observed. The geometry and composition of seismogenic faults controls the nucleation, propagation and termination of the earthquake rupture process. This study aims to place constraints on the geometry and composition of seismogenic faults by examining ancient faults exhumed from the depths at which earthquakes are observed to nucleate. Faults exposed in the Sierra Nevada, California, show that the internal architecture of earthquake faults is heterogeneous at a variety of scales. Field and microstructural observations are used to describe in detail the architecture of two pseudotachylyte-bearing fault systems in the Granite Pass region of Sequoia and Kings Canyon National Park; the Granite Pass fault (GPF) and associated faults, and the Glacier Lakes fault (GLF) and faults that splay from the GLF. The GPF and sub-parallel faults are 1 to 6.7km long with left-lateral strike-slip displacements up to 80m. The GPF and GPF-parallel faults have architectures that are heterogeneous along strike. They are composed of one to four fault core strands containing cataclasites and ultracataclasites that cross-cut early localized crystal-plastic deformation. Slip surfaces developed at the edges of, within and between fault cores are defined by pseudotachylytes and cataclasites with thicknesses of ~0.01 to 20mm. Fault-related subsidiary structures are developed on either side of fault cores, and comprise damage zones with widths orthogonal to the fault of up to 30m. The GLF and splay faults have architectures that are more homogeneous along strike. These faults are composed of a tabular volume of heavily fractured and altered host rock between approximately planar fault core strands. The fault cores are centimetres wide and contain cataclasites and foliated cataclasites that are cross-cut by pseudotachylytes. Fault-related damage is limited in extent to several metres beyond the bounding fault cores. The GLF contains additional cataclasites, ultracataclasites and pseudotachylytes in a fault core strand within the tabular zone of fractured rock. Thermochronologic analyses of the host rock granodiorite, combined with previously published palaeogeobarometry and apatite fission track data, define the temperature and pressure changes associated with cooling and exhumation of the pluton. The P-T conditions prevalent during the deformation history of the GPF fault system are evaluated by relating recrystallisation mechanisms in quartz to temperature, showing that the early stages of deformation occurred at temperatures of 450 to 600ºC. Dating of pseudotachylytes by the K-Ar isotopic method suggests subsequent brittle deformation took place at temperatures <350ºC and pressures ≤150MPa. A model for the architecture of the GPF architecture therefore has well constrained environmental controls, and should be transferrable to faults with comparable deformation histories. Small faults (cumulative displacements <1m) in the Mount Abbot Quadrangle, 55km north of Granite Pass, have been examined to illustrate the processes associated with the earliest stages of slip in the Sierra Nevada faults. The faults have branched or straight fault traces. Pseudotachylytes in branching faults show that these faults accumulated displacement in high velocity slip events, rather than by quasi-static fault growth. Branching faults without pseudotachylytes contain chlorite breccias interpreted to have formed in response to slip along faults with elevated pore fluid pressure. Straight faults also likely underwent slip events, but contain cataclased chlorite and epidote, suggesting low fluid pressures during slip. The small faults show that fluid-rock interactions are critical to fault geometry, and that lateral structural heterogeneity is established after small finite displacements. Field and thin section observations of exhumed seismogenic faults show that fault architecture and fault rock assemblage are critical to the earthquake rupture process. The heterogeneous composition of slip surfaces in the GPF faults imply that melt lubrication cannot account for all of the dynamic slip weakening as there are no continuous pseudotachylyte generation surfaces through the fault zones. Multiple slip weakening mechanisms must have been active during single rupture events. Slip weakening mechanisms also change at a given point on the fault in response to continued deformation. Splay faults at the GLF termination suggest that structural complexity observed at the terminations of fault surface traces can also be expected at depth. The off-fault damage at the termination of the GLF will change the bulk elastic properties of the host rock and must be accounted for in models of rupture propagation beyond fault terminations, or across geometrical discontinuities. Additionally, aftershock distributions and focal mechanisms may be controlled by the geometry of structures present at fault terminations

The relationship of body length to economically important swine production and carcass traits

A total of 1,062 purebred Duroc pigs of 168 litters by 14 sires provided data from five farrowing seasons at Ames Plantation (November, 1968, through November, 1969). Analyses were conducted to determine the phenotypic and genetic relationships of body length and various productivity and carcass traits and to estimate heritability of body length in order to assess the possible effectiveness of including this trait in a selection program, Phenotypic correlations among individual traits indicate that heavier weaning pigs reach 200 pounds at an earlier age, are longer and have less backfat and higher muscle scores than lighter weaning pigs. Body length was significantly (P \u3c .01) correlated with backfat (r = -.318). Also, pigs born with higher nipple counts tend to be longer at 200 pounds than pigs with fewer nipples. Phenotypically, dam body length was not significantly related to any litter production traits with the exception of litter average body length. Longer dams tended to produce longer litters at 200 pounds than shorter dams. Litter size at birth accounted for 60 percent of the variation in litter birth weight while litter size at weaning accounted for 79 percent of the variation in litter weaning weight. Genetic correlations among litter traits were very erratic with many of the standard errors larger than the estimates. Heritability estimates obtained from paternal half-sib correlations for litter averages of days to 200, body length and backfat were 0.51 ± 0.29, 0.51 ± 0.28 and 0,11 ± 0.18, respectively. The estimate of heritability of litter average body length computed by intra-sire regression of offspring on dam was 0.06 ± 0.01 which was interpreted as a possible consequence of appreciable maternal influence on body length. These data indicate that increasing dam body length would not significantly influence any pre-weaning or weaning traits
