Assessing economic and political impacts of Hydrological variability on treaties : case studies on the Zambezi and Mekong basins

2012-04-16T04:00:00.000Z

International river basins will likely face higher hydrologic variability due to climate change. Increased floods and droughts would have economic and political consequences. Riparians of transboundary basins governed by water treaties could experience non-compliance and inter-state tensions if flow falls below levels presumed in a treaty. Flow information is essential to cope with these challenges through water storage, allocation, and use. This paper demonstrates a simple yet robust method, which measures gauge station runoff with wetness values derived from satellite data (1988-2010), for expanding sub-basin stream flow information to the entire river basin where natural flow information is limited. It demonstrates the approach with flow level data that provide estimates of monthly runoff in near real time in two international river basins: Zambezi and Mekong. The paper includes an economic framework incorporating information on existing institutions to assess potential economic and political impacts and to inform policy on conflict and cooperation between riparians. The authors conclude that satellite data modeled with gauge station runoff reduce the uncertainty inherent in negotiating an international water agreement under increased hydrological variability, and thus can assist policy makers to devise more efficient institutional apparatus.

Female wages in the apparel industry post-MFA : the cases of Cambodia and Sri Lanka

2012-05-07T04:00:00.000Z

The end of the Multi-fiber Arrangement/Agreement on Textiles and Clothing in 2005 was a major policy change that affected the allocation of global apparel productions well as the lives of workers involved in this sector. Since the apparel industry is often the major female employer in developing countries, this policy change was expected to have major implications for women. This paper analyzes the wages and working conditions of women in the apparel sector in Cambodia and Sri Lanka following the phase-out the Multi-fibre Arrangement. In both countries, apparel is a major source of exports, and women constitute 70 to 80 percent of the workers employed in the apparel industry. The paper finds that after the removal of the Multi-fibre Arrangement, apparel prices declined as a result of the increased competition. The theoretical model suggests that a decrease in prices would lead to a decrease in apparel wage premiums relative to other industries in the short run and the widening of the male-female wage gap in the long run. The empirical findings support these theoretical predictions. Wage premiums in the apparel sector relative to other industries went down post-Multi-fibre Arrangement in Cambodia and Sri Lanka and the male-female wage gap increased. The paper finds mixed results in terms of working conditions in Cambodia and Sri Lanka.

Together we stand ? agglomeration in Indian manufacturing

2012-05-07T04:00:00.000Z

This paper uses plant-level data to examine the impact of industrial and trade policy reforms on the geographic concentration of manufacturing industries in India from 1980 to 1999. First, the research shows that de-licensing and liberalization in foreign direct investment significantly reduced spatial concentration, but trade reforms had no significant effect on spatial concentration. Second, plants respond differently to policy reforms based on their size. Liberalization in foreign direct investment and de-licensing caused small plants to disperse, while trade liberalization had the opposite effect. However, for large plants trade liberalization led to lower spatial concentration.

Economy-wide implications of direct and indirect policy interventions in the water sector: lessons from recent work and future research needs

2012-05-08T04:00:00.000Z

Water is increasingly becoming a limiting factor for sustainable economic growth and development in many countries. Its allocation has significant impacts on overall economic efficiency, particularly with growing physical scarcity in certain regions. Greater water supply variability further increases vulnerability in affected regions. Water also has become a strategic resource involving conflicts among those who may be affected differently by various policies. This paper analyzes various policy interventions aimed at improving water allocation decisions, using a novel approach that incorporates macro and micro level considerations in a unified analytical framework. The framework facilitates assessment of various linkages among policies and their impacts within individual sectors and economy-wide. Drawing on country based studies in Morocco, South Africa, Turkey, and Mexico, the analysis reveals difficult tradeoffs among various policy objectives, including priorities placed on different sectors, regional advantages, and general economic efficiency gains versus broader social impacts. The comparison of policy impacts demonstrates the usefulness of the framework in information that policy makers can use to rank the policy interventions according to the emphasis placed on different policy objectives. The paper also compares approaches used in other studies that apply computable general equilibrium models in various contexts of water, environment and agriculture.

Aligning climate change mitigation and agricultural policies in Eastern Europe and Central Asia

2012-06-06T04:00:00.000Z

Greenhouse gas emissions are largely determined by how energy is created and used, and policies designed to encourage mitigation efforts reflect this reality. However, an unintended consequence of an energy-focused strategy is that the set of policy instruments needed to tap mitigation opportunities in agriculture is incomplete. In particular, market-linked incentives to achieve mitigation targets are disconnected from efforts to better manage carbon sequestered in agricultural land. This is especially important for many countries in Eastern Europe and Central Asia where once-productive land has been degraded through poor agricultural practices. Often good agricultural policies and prudent natural resource management can compensate for missing links to mitigation incentives, but only partially. At the same time, two international project-based programs, Joint Implementation and the Clean Development Mechanism, have been used to finance other types of agricultural mitigation efforts worldwide. Even so, a review of projects suggests that few countries in Eastern Europe and Central Asia take full advantage of these financing paths. This paper discusses mitigation opportunities in the region, the reach of current mitigation incentives, and missed mitigation opportunities in agriculture. The paper concludes with a discussion of alternative policies designed to jointly promote mitigation and co-benefits for agriculture and the environment.

The future of the Nuclear industry reconsidered : risks, uncertainties, and continued potential

2012-06-29T04:00:00.000Z

Skeptics point out, with some justification, that the nuclear industry's prospects were dimmed by escalating costs long before Fukushima. If history is any guide, one direct consequence of the calamity in Japan will be more stringent safety requirements and regulatory delays that will inevitably increase the costs of nuclear power and further undermine its economic viability. For nuclear power to play a major role in meeting the future global energy needs and mitigating the threat of climate change, the hazards of another Fukushima and the construction delays and costs escalation that have plagued the industry will have to be substantially reduced. One promising direction for nuclear development might be to downsize reactors from the gigawatt scale to less-complex smaller units that are more affordable. Small modular reactors (SMRs) are scalable nuclear power plant designs that promise to reduce investment risks through incremental capacity expansion; become more standardized and reduce costs through accelerated learning effects; and address concerns about catastrophic events, since they contain substantially smaller radioactive inventory. Given their lower capital requirements and small size, which makes them suitable for small electric grids, SMRs can more effectively address the energy needs of small developing countries.

Poverty and distributional impact of gas price hike in Armenia

2012-07-30T04:00:00.000Z

Armenia meets about 75 percent of its energy needs through imports, with natural gas imports from Russia accounting for about 80 percent of total energy imports and 60 percent of total primary energy supply. Because of high dependence on imported energy, Armenia is vulnerable to external energy price shocks, which are often beyond the control of its policymakers. A most recent case in point was the 2010 Russian gas tariff increase, which led to a nearly 40 percent increase in the retail gas price for residential consumers. Coming on the heels of the global economic recession that hit Armenia's economy hard, the price hike amplified the impact on households that rely primarily on gas for heating and cooking. Using aggregate energy consumption data and a nationally representative household survey immediately before the crisis, this paper provides an overview of household energy consumption patterns, highlights Armenia's energy vulnerability, and estimates the direct poverty and distributional impacts of the increase in the cost of imported gas. The analysis shows that the gas price hike resulted in a significant increase in energy expenditures, with disproportionately higher impact on the poor and vulnerable households. The paper concludes with a discussion on the effectiveness of the mitigation measures employed by the Government of Armenia.

What explains big gender disparities in India ? local industrial structures and female entrepreneurship

2012-10-15T04:00:00.000Z

Despite rapid economic growth, gender disparities in women's economic participation have remained deep and persistent in India. What explains these huge gender disparities? Is it poor infrastructure, limited education, and gender composition of the labor force and industries? Or is it deficiencies in social and business networks and a low share of incumbent female entrepreneurs?This paper analyzes the spatial determinants of female entrepreneurship in India in the manufacturing and services sectors. Good infrastructure and education predict higher female entry shares. There are strong agglomeration economies in both manufacturing and services, where higher female ownership among incumbent businesses within a district-industry predicts a greater share of subsequent entrepreneurs will be female. Moreover, higher female ownership of local businesses in related industries (similar labor needs, input-output markets) predicts greater relative female entry rates. Gender networks thus clearly matter for women's economic participation. However, there is a need to develop a better understanding of how gender networks influence aggregate efficiency. There is no doubt that gender empowerment can be the escalator to realizing human potential and for creating a robust platform for growth and job creation.

Sea-level rise and coastal wetlands : impacts and costs

2012-11-26T05:00:00.000Z

Scientific evidence indicates that global warming could well lead to a sea-level rise of 1 meter or more in the 21st century. This paper seeks to quantify how a 1-meter sea-level rise that would affect coastal wetlands in 76 developing countries and territories, taking into account how much of wetlands would be submerged and how likely the wetlands would move inland as the coastline recedes. It is estimated that approximately 64 percent of the freshwater marsh, 66 percent of Global Lakes and Wetlands Database coastal wetlands, and 61 percent of brackish/saline wetlands are at risk. A large percentage of this loss would be shouldered by two regions: East Asia and the Pacific, and the Middle East and North Africa. At the country level, the results are extremely skewed with a small number of countries being severely affected. In East Asia, China and Vietnam would bear the brunt of these losses. In the Middle East and North Africa, Libya and Egypt would see the most losses. A rough estimate of the economic value of the goods and services produced by wetlands at risk is approximately $630 million per year in 2000 U.S. dollars.

Rainfall variability, occupational choice, and welfare in rural Bangladesh

2013-01-14T05:00:00.000Z

This study investigates the choice of occupational focus versus diversification between household members in rural Bangladesh as an autonomous and proactive adaptation strategy against ex ante local rainfall variability risks. The analysis combines nationally representative household level survey data with historical climate variability information at the Upazila level. The authors note that flood prone Upazilas may face reduced risks from local rainfall variability as compared with non-flood prone Upazilas. They find that two members of the same household are less likely to be self-employed in agriculture if they live in an area with high local rainfall variability. However, the occupational diversification strategy comes at a cost to households in terms of consumption welfare. The paper considers the effects of three policy actions, providing access to credit, safety net, and market. Access to market appears to be more effective in reducing the likelihood of costly within-household occupational diversification as an ex ante climate risk-reducing strategy as compared with access to credit and safety net.

Antidumping, retaliation threats, and export prices

2013-01-15T05:00:00.000Z

Utilizing four-dimensional (firm-product-destination-year) Brazilian firm-level export data, the paper shows that antidumping (AD) duties result in a significant and dramatic increase in the unit values of the products that firms export to duty-imposing countries. Furthermore, it examines the effect of potential (retaliatory) AD duties on the unit price of the firms' shipments. The findings suggest that AD activities in Brazil lead Brazilian exporting firms to increase their unit export prices for the named industries' products to decrease the dumping margin and avoid the threat of retaliation by the target countries.

Water nationalization and service quality

2013-01-15T05:00:00.000Z

The objective of this paper is to explore the impact of Uruguay's privatization and subsequent nationalization of water services on network access and water quality. The results suggest that although the early privatization of water services had little impact on access to the sanitation network, the subsequent nationalization led to an increase in network access at the bottom of the income distribution as well as an improvement in water quality.

Political reservations and women's entrepreneurship in India

2013-02-13T05:00:00.000Z

This paper quantifies the link between the timing of state-level implementations of political reservations for women in India with the role of women in India's manufacturing sector. It does not find evidence that overall employment of women in manufacturing increased after the reforms. However, the analysis finds significant evidence that more women-owned establishments were created in the unorganized/informal sector. These establishments were concentrated in industries where women entrepreneurs have been traditionally active and the entry was mainly found among household-based establishments. This heightened entrepreneurship does not appear linked to changes in reporting, better access to government contracts and business, or improved financing environments. One interpretation of these results is that the implementation of the political reservations inspired more women to open establishments, and they did so at a small establishment scale in industries where they had experience and/or the support networks of other women.

How different are safeguards from antidumping ? evidence from us trade policies toward steel

2013-03-04T05:00:00.000Z

Use of temporary trade barriers has proliferated across countries, industries, and even policy instruments. This paper constructs a panel of bilateral, product-level United States steel imports that are matched to a unique data set on trade policy exclusions that are associated with the 2002 United States steel safeguard in order to compare the trade impacts that result from application of various temporary trade barrier policies over 1989-2003. The analysis finds that the trade effects of an applied safeguard -- which is statutorily expected to follow the principle of nondiscriminatory treatment -- can nevertheless compare closely with the application of the explicitly discriminatory antidumping policy. The results on trade policy substitutability complement other recent research on these increasingly important forms of import protection.

Monsoon babies : rainfall shocks and child nutrition in Nepal

2013-03-28T04:00:00.000Z

Do household consumption-smoothing strategies in poor countries entail significant long-run costs in terms of reduced human capital? This paper exploits the timing of monsoon rainfall shocks and the seasonal nature of agriculture to isolate income effects on early childhood anthropometric outcomes in rural Nepal and to provide evidence on the persistence of these effects into later childhood. Findings suggest that a 10 percent increase in rainfall from historic norms during the most recently completed monsoon leads to a 0.15 standard deviation increase in weight-for-age for children ages 0-36 months. This total impact consists of a negative "disease environment effect" of no more than 0.02 standard deviations and a positive "income effect" as high as 0.17 standard deviations. Consistent with this interpretation, excess monsoon rainfall also enhances child stature, but only if the monsoon rainfall shock is experienced in the second year of life. Moreover, this effect on child height is transitory, dissipating completely by age five.

Chinese firms' entry to export markets : the role of foreign export spillovers

2013-04-04T04:00:00.000Z

In this paper, the effect of proximity to multinational exporters on the creation of new export linkages (the extensive margin of trade) is debated. Using panel data from Chinese customs for 1997-2007, the capacity for Chinese domestic firms to begin exporting new varieties to new markets is shown to respond positively to the export activity of neighboring foreign firms. These spillovers are shown to be product and country specific. This conclusion is robust to fixed effects and instrumental variable specifications that control for both supply and demand shocks that could bias the estimations. The impact is sizable. The marginal impact of product-country-specific foreign export spillovers is five times as large as the effect of a 10 percent increase in the demand for the product in the destination country. Foreign export spillovers are also shown to be primarily limited to ordinary trade activities. Overall, our findings suggest that even for a country with an important cost-advantage such as China, there is room for initiatives from policy-makers that will diffuse best practices regarding export experience among exporters.

Water hauling and girls' school attendance : some new evidence from Ghana

2013-05-15T04:00:00.000Z

In large parts of the world, a lack of home tap water burdens households as the water must be brought to the house from outside, at great expense in terms of effort and time. This paper studies how such costs affect girls' schooling in Ghana, with an analysis based on four rounds of the Demographic and Health Surveys. Using Global Positioning System coordinates, it builds an artificial panel of clusters, identifying the closest neighbors within each round. The results indicate a significant negative relation between girls' school attendance and water hauling activity, as a halving of water fetching time increases girls' school attendance by 2.4 percentage points on average, with stronger impacts in rural communities. The results seem to be the first definitive documentation of such a relationship in Africa. They document some of the multiple and wide population benefits of increased tap water access, in Africa and elsewhere.

The exceptional persistence of India's unorganized sector

2013-05-21T04:00:00.000Z

The transformation of India's unorganized sector is important to its modernization, growth, and attainment of regional economic equality. This paper documents several key facts about India's unorganized sector in manufacturing and services. First, the unorganized sector is large, accounting for more than 99 percent of establishments and 80 percent of employment in manufacturing. Second, the unorganized sector is stubbornly persistent -- it accounted for 81 percent of manufacturing employment in 1989 and 2005. Third, this persistence is not due to particular subsets of industries or states, as most industries and states show limited change in unorganized sector employment shares. Fourth, the degree to which localized unorganized activity exists is important as it is associated with weaker production functions for manufacturing firms. Building from these facts, the paper investigates conditions promoting transformation by state-industry. Decomposition exercises find that both within and between adjustments for state-industries weakly reduce unorganized sector shares. The aggregate persistence instead comes from the covariance term, where fast-growing state-industries witness rising unorganized sector activity. Regressions quantify that growth in the organized sector by state-industry reduces the unorganized sector employment share, but only marginally reduces employment levels in unorganized activity. Analysis of the establishment size distribution highlights that entrepreneurship and larger organized sector plants are most important for transitions in the manufacturing sector, while small establishments play a key role in the services sector.

Blue water and the consequences of alternative food security policies in the Middle East and North Africa for water security

2013-05-29T04:00:00.000Z

In the Middle East and North Africa, food security and water security are tightly entwined. In particular, choices about the extent to which food security policies rely on trade rather than domestically produced staples have stark consequences for the region's limited water resources. This paper builds on previous modeling results comparing the cost and benefits of policies to protect consumers against surging international wheat prices, and expands the analysis to consider the consequences of the policies for water resources. A self-sufficiency policy is analyzed as well. Results suggest that trade-based food security policies have no significant effect on the sustainability of water resources, while the costs of policies based on self-sufficiency for water resources are high. The analysis also shows that while information about the water footprint of alternative production systems is helpful, a corresponding economic footprint that fully measures the resource cost of water is needed to concisely rank alternative policies in economic terms that are consistent with sustainable outcomes.

Export diversification in twelve European and Central Asian countries and the role of the commodity boom

2013-06-03T04:00:00.000Z

This paper examines export diversification along the product and market dimensions for selected countries in the Europe and Central Asia region and, more generally, export performance. While the latter is extraordinary, with average export growth rates above 10 percent, the evidence on diversification is less impressive, and hints at a role played by the interaction of natural resource abundance and the commodity price boom. A cross-country analysis including 171 economies suggests that the region's resource rich countries are less diversified than would be expected given their resource endowments, level of development, and size. The commodity boom period was associated with an increase in concentration for the resource rich along the product dimension: they did not increase the number of products exported and became more reliant on oil and gas. During the same period, the resource poor increased their export product scope while maintaining other concentration indices unchanged. A similar but milder pattern is found for diversification along the destination dimension.
