Access to markets and the benefits of rural roads
Transport infrastructure plays a central role in rural development, yet little is known about the size - or, especially, the distribution - of benefits from road investments. Among other benefits, rural roads provide cheaper access to both markets for agricultural output and for modern inputs. The author develops and implements a method for nonparametrically estimating the benefits from road projects at the household level. The idea is that since these benefits get capitalized in land values, they can be estimated by examining how the value of farmland falls with distance from agricultural markets. Household-level benefits from hypothetical road projects are calculated from the predicted appreciation in value of the household's farmland. These predicted benefits are then related to household per-capita expenditures to assess their distributional consequences. The empirical analysis, using data from Nepal, shows large benefits from extending roads into remote rural areas, much of these gains going to poorer households. But rural road construction is not the magic bullet for poverty alleviation. The benefits are neither large enough nor targetedwell enough to reduce income inequality appreciably.Health Economics&Finance,Environmental Economics&Policies,Banks&Banking Reform,Economic Theory&Research,Labor Policies,Economic Theory&Research,Environmental Economics&Policies,Health Economics&Finance,Banks&Banking Reform,Roads&Highways
Incentives, supervision, and sharecropper productivity
Although sharecropping has long fascinated economists, the determinants of this contractual form are still poorly understood and the debate over the extent of moral hazard is far from settled. The authors address both issues by emphasizing the role of landlord supervision. When tenant effort is observable, but at a cost to the landlord, otherwise identical share-tenants can receive different levels of supervision and have different productivity. Unique data on monitoring frequency collected from sharetenants in rural Pakistan confirm that, controlling for selection,"supervised"tenants are significantly more productive than"unsupervised"ones. Landlords'decisions regarding the intensity of supervision and the type of incentive contract to offer depend importantly on the cost of supervising tenants.Contract Law,Economic Theory&Research,Investment and Investment Climate,Municipal Housing and Land,Urban Housing
Watta satta : bride exchange and women's welfare in rural Pakistan
In a setting where husbands wield considerable coercive power, forms of marriage should adapt to protect the interests of women and their families. The authors study the pervasive marriage custom of watta satta in rural Pakistan, a bride exchange between families coupled with a mutual threat of retaliation. They show that watta satta may be a mechanism to coordinate the actions of two sets of in-laws, each of whom wish to restrain their sons-in-law but who only have the ability to restrain their sons. The authors'empirical results support this view. The likelihood of marital inefficiency, as measured by estrangement, domestic abuse, and wife's mental health, is significantly lower in watta satta arrangements as compared with conventional marriages, but only after properly accounting for selection.Population&Development,Anthropology,Education and Society,Gender and Law,Gender and Law
Crossing boundaries : gender, caste and schooling in rural Pakistan
Can communal heterogeneity explain persistent educational inequities in developing countries? The paper uses a novel data-set from rural Pakistan that explicitly recognizes the geographic structure of villages and the social makeup of constituent hamlets to show that demand for schooling is sensitive to the allocation of schools across ethnically fragmented communities. The analysis focuses on two types of social barriers: stigma based on caste affiliation and female seclusion that is more rigidly enforced outside a girl's own hamlet. Results indicate a substantial decrease in primary school enrollment rates for girls who have to cross hamlet boundaries to attend, irrespective of school distance, an effect not present for boys. However, low-caste children, both boys and girls, are deterred from enrolling when the most convenient school is in a hamlet dominated by high-caste households. In particular, low-caste girls, the most educationally disadvantaged group, benefit from improved school access only when the school is also caste-concordant. A policy experiment indicates that providing schools in low-caste dominant hamlets would increase overall enrollment by almost twice as much as a policy of placing a school in every unserved hamlet, and would do so at one-sixth of the cost.Primary Education,Education For All,Disability,Adolescent Health,Tertiary Education
On measuring the benefits of lower transport costs
Despite large amounts invested in rural roads in developing countries, little is known about their benefits. This paper derives an expression for the willingness-to-pay for a reduction in transport costs from the canonical agricultural household model and uses it to estimate the benefits of a hypothetical road project. Estimation is based on novel cross-sectional data collected in a small region of Madagascar with enormous, yet plausibly exogenous, variation in transport cost. A road that essentially eliminated transport costs in the study area would boost the incomes of the remotest households-those facing transport costs of about USD 75/ton-by nearly half, mostly by raising non-farm earnings. This benefit estimate is contrasted to one based on a hedonic approach.Transport Economics Policy&Planning,Rural Roads&Transport,Economic Theory&Research,Rural Transport,
Incomplete contracts and investment : a study of land tenancy in Pakistan
When contracts are incomplete, relationship-specific investments may be underprovided due to the threat of opportunistic expropriation or holdup. The authors find evidence of such underinvestment on tenanted land in rural Pakistan. Using data from households cultivating multiple plots under different tenure arrangements, they show that land-specific investment is lower on leased plots. This result is robust to the possible effects of asymmetric information in the leasing market. Greater tenure security also increases land-specific investment on leased plots. Moreover, variation in tenure security appears to be driven largely by heterogeneity across landlords, suggesting that reputation may be important in mitigating the holdup problem.Investment and Investment Climate,Municipal Housing and Land,Contract Law,Economic Theory&Research,Real Estate Development
HAZARDS OF EXPROPRIATION:TENURE INSECURITY AND INVESTMENT IN RURAL CHINA
This paper uses household data from Northeast China to examine the link between investment and land tenure insecurity induced by China's system of village-level land reallocation. We quantify expropriation risk using a hazard analysis of individual plot tenures and incorporate the predicted hazards of expropriation into an empirical analysis of plot-level investment. Our focus is on organic fertilizer use, which has long lasting benefits for soil quality. Although we find that higher expropriation risk significantly reduces application of organic fertilizer, a welfare analysis shows that guaranteeing land tenure in this part of China would yield only minimal efficiency gains.Land Economics/Use,
Harmonic Love wave devices for biosensing applications
Simultaneous operation of a Love wave biosensor at the fundamental frequency and third harmonic, including the optimisation of IDT metallisation thickness, has been investigated. Data is presented showing a sequence of deposition and removal of a model mass layer of palmitoyl-oleoyl-sn-glycerophosphocholine (POPC) vesicles while frequency hopping between 110 and 330 MH
Monopoly power and distribution in fragmented markets : the case of groundwater
Using data from Pakistan's Punjab, the authors examine monopoly power in the market for groundwater - irrigation water extracted using private tubewells - a market characterized by barriers to entry and spatial fragmentation. Simple theory predicts that tubewell owners should price-discriminate in favor of their own share tenants. And this analysis of individual groundwater transactions over an 18-month period confirms such price discrimination. And among those studied, tubewell owners and their tenants use considerably more groundwater on their plots than do other farmers. The authors also provide evidence that monopoly pricing of groundwater leads to compensating - albeit small - reallocations of canal water, which farmers exchange in a separate informal market. Despite the substantial misallocation of groundwater, a welfare analysis show that monopoly pricing has limited effects on equity and efficiency. In the long run, a policy aimed at eliminating monopoly pricing would do little to help the poorest farmers.Water and Industry,Water Resources Law,Water Conservation,Environmental Economics&Policies,Water Supply and Systems,Water and Industry,Water Conservation,Water Supply and Sanitation Governance and Institutions,Drought Management,Water Use
