Rural nonfarm employment : a survey

So little is known about the rural nonfarm sector that those making policy to assist rural small-scale enterprises have done so largely"unencumbered by evidence". The Lanjouw survey of nonfarm data and policy experience attempts to correct this. Until recently, the commonly held view was that rural nonfarm employment was relatively nonproductive, producing goods and services of low quality. The rural off-farm sector was expected to wither away with development and rising incomes, and this was viewed as a positive, rather than a negative, event. A corrollary of this view was that the government need not actively worry about the sector -- or be concerned about how policies elsewhere might harm it. More recently, opinion has swung the other way, and it is increasingly argued that neglect of the sector would be mistaken. The survey highlights the positive roles that the rural nonfarm sector can play in promoting both growth and welfare. In the widespread situation of a rural workforce growing faster than the employment potential in agriculture, the nonfarm rural sector can lower unemployment and slow rural-urban migration. It is particularly useful in employing women and providing off-season incomes. The technologies used in small-scale rural manufacturing may be more appropriate and thus generate greater income from available productive inputs. What role could government play in promoting the nonfarm sector? The emphasis of government policy has been on large-scale urban industry as the main engine of growth. More recently, there has been a move toward a more"broad-based growth"approach, with greater emphasis on the development of agriculture and the rural economy. Increasingly countries have targeted project assistance schemes, for example to provide training, infrastructure, and technology to support small-scale and rural enterprises. Nonetheless, in most countries it remains true that projects to support the nonfarm rural sector are undertaken in a policy environment which is biased against this sector.Environmental Economics&Policies,Municipal Financial Management,Economic Theory&Research,Banks&Banking Reform,Labor Policies,Environmental Economics&Policies,Economic Theory&Research,Banks&Banking Reform,Municipal Financial Management,Crops&Crop Management Systems

Combining census and survey data to study spatial dimensions of poverty

Poverty maps, providing information on the spatial distribution of living standards, are an important tool for policy making and economic research. Policymakers can use such maps to allocate transfers and inform policy design. The maps can also be used to investigate the relationship between growth and distribution inside a country, thereby complementing research using cross-county regressions. The development of detailed poverty maps is difficult because of data constraints. Household surveys contain data on income or consumption but are typically small. Census data cover a large sample but do not generally contain the right information. Poverty maps based on census data but constructed in an ad-hoc manner can be unreliable. The authors demonstrate how sample survey data and census data can be combined to yield predicted poverty rates for all households covered by the census. This represents an improvement over ad hoc poverty maps. However, standard errors on the estimated poverty rates are not negligible, so additional efforts to cross-check results are warranted.Health Economics&Finance,Environmental Economics&Policies,Services&Transfers to Poor,Poverty Monitoring&Analysis,Public Health Promotion,Poverty Monitoring&Analysis,Health Economics&Finance,Poverty Assessment,Environmental Economics&Policies,VN-Acb Mis -- IFC-00535908

Financing Pharmaceutical Innovation: How Much Should Poor Countries Contribute?

We use a public economics framework to consider how pharmaceuticals should be priced when at least some of the R&D incentive comes from sales revenues. We employ familiar techniques of public finance to relax some of the restrictions implied in the standard use of Ramsey pricing. In the more general model, poor countries should not necessarily cover even their own marginal costs, and the pricing structure is not related to that which would be chosen by a monopolist in a simple way. We use this framework to examine on-going debates regarding the international patent system as embodied in the WTO’s TRIPS agreement.pharmaceutical, poor countries, pricing structure, patent system

Enforcing Intellectual Property Rights

We study the determinants of patent suits and their outcomes over the period 1978-1999 by linking detailed information from the U.S. patent office, the federal court system, and industry sources. The probability of being involved in a suit is very heterogeneous, being much higher for valuable patents and for patents owned by individuals and smaller firms. Thus the patent system generates incentives, net of expected enforcement costs, that differ across inventors. Patentees with a large portfolio of patents to trade, or having other characteristics that encourage 'cooperative' interaction with disputants, more successfully avoid court actions. At the same time, key post-suit outcomes do not depend on observed characteristics. This is good news: advantages in settlement are exercised quickly, before extensive legal proceedings consume both court and firm resources. But it is bad news in that the more frequent involvement of smaller patentees in court actions is not offset by a more rapid resolution of their suits. However, our estimates of the heterogeneity in litigation risk can facilitate development of private patent litigation insurance to mitigate this adverse affect of high enforcement costs.

The Quality of Ideas: Measuring Innovation with Multiple Indicators

We model early expectations about the value and technological importance ('quality') of a patented innovation as a latent variable common to a set of four indicators: the number of patent claims, forward citations, backward citations and family size. The model is estimated for four technology areas using a sample of about 8000 U.S. patents applied for during 1960-91. We measure how much noise' each individual indicator contains and construct a more informative, composite measure of quality. The variance in quality', conditional on the four indicators, is just one-third of the unconditional variance. We show the variance reduction generated by subsets of indicators, and find forward citations to be particularly important. Our measure of quality is significantly related to subsequent decisions to renew a patent and to litigate infringements. Using patent and R&D data for 100 U.S. manufacturing firms, we find that adjusting for quality removes much of the apparent decline in research productivity (patent counts per R&D) observed at the aggregate level.

Untitled: A Study of Formal and Informal Property Rights in Urban Ecuador

In this paper we explore the substitutability of formal and informal property rights. We analyze new survey data from Ecuador, where households have both formal and informal claims to urban residential property. The latter come from a variety of sources, including the activity of a local boss, or organizer. We first develop a theory of the ability to sell or rent land in which a distinction is drawn between transferable property rights (e.g., title) and non-transferable claims (e.g., length of residence). We use this theory of transactions to show that the increase in price that follows the granting of title may be an overestimate of the households' utility gain. In our empirical work we find that the unconditional effect of granting title is to raise properties' value by 23.5%. However, we also find that informal property rights can substitute effectively for formal property rights, so the marginal effect of titling on the ability to transact and on prices can vary widely among communities and among households within a community. For example, the value of property owned by a newly established household with no adult males can increase by 46% with the acquisition of title. These findings suggest that titling programs should be targeted at young disorganized communities if they are to have much effect.
