Urban land expansion in Indonesia 1992–2012: evidence from satellite‐detected luminosity

Land conversion to urban use typically accompanies economic development but raises concerns about food security. Debates of these issues often rely on incomplete and incompatible evidence. This study uses satellite‐detected luminosity, from 1992 to 2012, to examine the urban land expansion of 41 major urban areas in Indonesia. The trend annual expansion rate is 2.0 per cent, which is comparable to the rate for India and just one‐third of the rate for China, as estimated with the same data and methods. Prior to the Asian Financial Crisis in 1997/98, the rate of urban expansion was faster, and the income elasticity of urban expansion was much higher. About 85 per cent of the area of urban expansion had formerly been grassland, shrub or woodland, and just 7.0 per cent was former cropland so food security concerns about urban expansion may be overstated.     

Real wages, employment and macroeconomic policy in a structuralist model for South Africa

It is now commonplace to argue that in South Africa, like manydeveloping countries, higher wages will lower employment. Thispaper shows that it is difficult to extricate the relationshipbetween wages, employment and output from the macropolicy environment.Dynamic computable general equilibrium simulations show thatthe employment effects of nominal wage increases depends oninduced monetary and fiscal policy when there is monetary 'policydominance'. While wage-led growth is inefficient, increasingthe wages of unskilled workers can improve the distributionof income, when the induced changes are neutralised.     

Impact of wireless telecommunications standards and regulation on the evolution of wireless technologies and services over Internet protocol

Beginning with the historical role and importance of multi-physical standards in wireless telecommunications for the future in the US, Japan and Europe, this paper provides a cohesive vision of how wireless communication, voice over Internet protocol (VoIP) is likely to develop. Also covered in this paper are its benefits, the technical and regulatory support required to realize this vision and an assessment of its potential impact on the structure of the telecommunications industry. Although the competitive structure of the Internet is relatively open, several factors, such as frequency allocation policy and radio interface standards, could block the efficient evolution of wireless services to an IP platform. The paper proposes two major technical requirements to enable effective competition in wireless VoIP and achieve greater technical productivity.     

Technological and geographic heterogeneity in broadband markets: The challenge for regulation

When the telecommunications industry was liberalised in Europe and North America in the 1980s and 1990s, it inherited a legacy of monopoly providers whose footprint was national or multi-regional in its character. The regulatory framework, particularly that adopted in EU member states, reflected this pattern of relatively homogeneous deployment achieved, in part, by decades of cross-subsidised pricing and universal service goals. Perhaps because of this legacy, telecommunications regulators have often adopted the presumption that relevant markets are national in character, unless proven otherwise Although geographically-variegated regulatory remedies have been permitted (even in the face of allegedly national relevant markets) and adopted in many member states, many regulators have never done so, and overly cautious thresholds for permitting geographically based forbearance suggest a continued bias towards presuming national markets and remedies. We find that this presumption of uniformity and the tendency to aggregate geographic markets together is not supported by first principles of antitrust analysis, although there may have been strong practical reasons to apply this presumption in the past circumstances of the telecommunications and broadband industries.On the ground, however, there has arguably never been as much heterogeneity across geographies and across technological solutions that provide effective ultra-fast broadband speeds. Both technological (i.e., product market) and geographic heterogeneity are likely to increase with the advent of mobile 5G networks. With their deployment, a cautious regulatory stance towards geographic variation and a cautious regulatory stance towards inter-technology or inter-modal competition may result in regulation that could exceed what is required to ensure effective competition and could instead distort the incentives to enter of facilities-based actors. This may also result in higher-cost and inefficient investment. A more geographically varied and technologically agnostic regulatory framework may satisfy the principle of proportionate and focused regulation—with the possibility that the locus of regulation shifts from the access network to bottleneck facilities such as fibre, ducts and poles.This discussion is especially germane when one considers the highly speculative nature of forecasts and projections about future demand, and the competing claims of proponents of 5G and fibre. While there is some scepticism about the performance of mobile networks, we note that pure mobile and fixed 5G services may have synergies in deployment, and that the idea of competing with residential broadband services is a core strategy of very influential large-scale industry actors. In terms of a future research agenda, regulatory decisions could benefit from much more research into the relationship between domestic and global bandwidth constraints and their influence on development of software and application, as well as much more quantitative research by academics on the drivers of bandwidth demand. The risks associated with promoting investment that results in large-scale wasted resources should also be central to the regulatory agenda.     

NIGHT LIGHTS IN ECONOMICS: SOURCES AND USES1

Night lights, as detected by satellites, are increasingly used by economists, typically as a proxy for economic activity. The growing popularity of these data reflects either the absence, or the presumed inaccuracy, of more conventional economic statistics, like national or regional GDP. Further growth in use of night lights is likely, as they have been included in the AidData geoquery tool for providing subnational data, and in geographic data that the Demographic and Health Survey links to anonymized survey enumeration areas. Yet, this ease of obtaining night lights data may lead to inappropriate use, if users fail to recognize that most of the satellites providing these data were not designed to assist economists, and have features that may threaten validity of analyses based on these data, especially for temporal comparisons, and for small and rural areas. In this paper, we review sources of satellite data on night lights, discuss issues with these data, and survey some of their uses in economics.     

CPI bias and real living standards in Russia during the transition

The economies of the former Soviet Bloc experienced large declines in output during the decade of transition which began with the collapse of the Soviet Union in 1991. Yet there are many reasons to believe that measured output and official deflators provide a poor proxy for the change in real living standards in transition economies. This paper uses the Engel curve methodology developed by Hamilton [Hamilton, B. 2001. “Using Engel's Law to Estimate CPI Bias” American Economic Review 91(3): 619–630] to examine changes in real living standards in Russia during the transition period and to provide an estimate of how much the official Russian CPI has overstated consumer inflation. We also examine changes in consumer durables, home production, and subjective well-being to further evaluate changes in living standards. Our findings indicate that CPI bias has caused a substantial understatement of the growth performance of the Russian economy during the transition. Even just allowing household final consumption to be deflated with bias, we find that the level of real per capita GDP in 2001 may be understated by up to 30% compared with using a bias-corrected deflator. Our analysis of consumer durables, home production, and subjective well-being supports the conclusion that the decline in living standards has been substantially less than what is inferred by looking at official statistics on real output.     

Methods of household consumption measurement through surveys: Experimental results from Tanzania

Surveys of consumption expenditure vary widely across many dimensions, including the level of reporting, the length of the reference period, and the degree of commodity detail. These variations occur both across countries and also over time within countries, with little current understanding of the implications of such changes for spatially and temporally consistent measurement of household consumption and poverty. A field experiment in Tanzania tests eight alternative methods of measuring household consumption, finding significant differences between consumption reported by the benchmark personal diary and other diary and recall formats. Under-reporting is particularly apparent for illiterate households and for urban respondents completing household diaries; recall modules measure lower consumption than a personal diary, with larger gaps among poorer households and for households with more adult members. Variations in reporting accuracy by household characteristics are also discussed and differences in measured poverty as a result of survey design are explored.     

Understanding women's accommodation experiences on girlfriend getaways: a pragmatic action research approach

In the realm of women's travel, while the accommodation experiences and preferences of female business travellers have been investigated, little is known about the female leisure-traveller in this regard. This study investigates one of the growth sectors in women's travel – girlfriend getaways (GGAs), which are holidays taken by females with other females. An action research approach was employed to explore the accommodation needs of all these female travel groups in the Malaysian context. Using a five-stage approach which included in-depth interviews, a hotel stay for three groups of women on a GGA, focus groups and secondary data analysis, four themes were identified. These themes address feminine comforts, facilitating friendship, safety, and shopping and the use of discount promotions with GGA. Findings suggest that the needs of female leisure-travellers are distinct from those of women who travel on business. Recommendations for hotel management are made to enhance the GGA experience for women, notably providing spaces and activities to facilitate female bonding.
