    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

    How good a map ? Putting small area estimation to the test

    Get PDF
    The authors examine the performance of small area welfare estimation. The method combines census and survey data to produce spatially disaggregated poverty and inequality estimates. To test the method, they compare predicted welfare indicators for a set of target populations with their true values. They construct target populations using actual data from a census of households in a set of rural Mexican communities. They examine estimates along three criteria: accuracy of confidence intervals, bias, and correlation with true values. The authors find that while point estimates are very stable, the precision of the estimates varies with alternative simulation methods. While the original approach of numerical gradient estimation yields standard errors that seem appropriate, some computationally less-intensive simulation procedures yield confidence intervals that are slightly too narrow. The precision of estimates is shown to diminish markedly if unobserved location effects at the village level are not well captured in underlying consumption models. With well specified models there is only slight evidence of bias, but the authors show that bias increases if underlying models fail to capture latent location effects. Correlations between estimated and true welfare at the local level are highest for mean expenditure and poverty measures and lower for inequality measures.Small Area Estimation Poverty Mapping,Rural Poverty Reduction,Science Education,Scientific Research&Science Parks,Population Policies

    Financing Pharmaceutical Innovation: How Much Should Poor Countries Contribute?

    Get PDF
    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

    The Quality of Ideas: Measuring Innovation with Multiple Indicators

    Get PDF
    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

    Get PDF
    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.

    Patents, Price Controls and Access to New Drugs: How Policy Affects Global Market Entry

    Get PDF
    We consider how patent rights and price regulation affect whether new drugs are marketed in a country, and how quickly. The analysis covers a large sample of 68 countries at all income levels and includes all drug launches over the period 1982-2002. It uses newly compiled information on legal and regulatory policy, and is the first systematic analysis of the determinants of drug launch in poor countries. Price control tends to discourage rapid product entry, while the results for patents are mixed. There is evidence that local capacity to innovate matters and that international pricing externalities may play a role.patent, drugs, access, market entry, price control

    Patents, Price Controls, and Access to New Drugs: How Policy Affects Global Market Entry

    Get PDF
    Efforts to strengthen the global patent system for pharmaceuticals continue to be controversial, and what will likely be a similarly fraught international debate over price controls has begun. The outcome of international negotiations and the resulting policy decisions made by each country will have many ramifications %u2013 influencing the size of future investment in medical research, the availability of the resulting therapies, how the financial burdens are distributed across countries, and finally the health of consumers. This paper considers how legal and regulatory policies affect whether new drugs are marketed in a country, and how quickly. Less than one-half of the new pharmaceutical molecules that are marketed worldwide are sold in any given country, and those that are sold are often available to consumers in one country only six or seven years after those in another. Both price regulation and intellectual property rights influence these outcomes. The analysis covers a large sample of 68 countries at all income levels and includes all drug launches over the period 1982-2002. It uses newly compiled information on legal and regulatory policy, and is the first systematic analysis of the determinants of drug launch in poor countries.
