Intergovernmental fiscal relations and poverty alleviation in Viet Nam

A successful poverty alleviation strategy has four distinct elements: 1) identifying who the poor are, where they are located, and what they do; 2) analyzing why they are poor; 3) developing policies to improve their standards of living; and 4) supplementing income-improving policies with direct"safety net"policies to increase the poor's short-term consumption etitlements. The precise mixture of"capacity-improving"investments and"safety net"policies appropriate for any country will depend on the country's income level, the extent and nature of its poverty problem, and many other factors. The strategy chosen must be implemented effectively. Spending and revenue decisions need to be more decentralized to ensure that the poverty alleviation policies adopted reflect the preferences, needs, and fiscal abilities of different regions of the country. The nature of that decentralization depends on the country. Pro-poor services throughout Viet Nam are underfunded. This problem is particularly acute in the poorer areas. Improvements in the system of intergovernmental finances could help ensure that each level of government, even in the poorer provinces, is adequately funded - and provided with sufficient expenditure and revenue raising autonomy - to support local investments and their operation and maintenance. Since poor provinces are less able to mobilize additional local revenues to support services, well-designed intergovernmental transfers are particularly important. Provinces must play a greater role both in raising revenues and in allocating expenditures, with incentives built in to ensure that they do so responsibly and efficiently. Local governments must - if they are tobe held accountable for their actions - have some responsibility for determining local tax rates. This will allow them to vary rates to collect more revenues to finance higher levels of public services if they so choose, and at the same time allow the central government to design its transfers in such a way as to ensure that local fiscal efforts are not discouraged by the receipt of such transfers. Richer provinces will tend to collect greater revenues. When transfers are needed to finance local spending in poorer areas, they should provide incentives for local revenue mobilization and allow for some degree of equalization. Services deemed of national importance (for example, a minimum level of education, health care, and social relief) can be promoted by designing specific-purpose transfers. These services must be identified and varying matching requirements established for different provinces depending on such factors as their own revenue base and the cost of providing services in that province.Municipal Financial Management,Public Sector Economics&Finance,Environmental Economics&Policies,Banks&Banking Reform,Decentralization,National Governance,Environmental Economics&Policies,Public Sector Economics&Finance,Health Economics&Finance,Banks&Banking Reform

Systematic screening of bryophytes for antitumor agents

References are made to cytotoxic and/or antitumor compounds that have been isolated - ansamitocin P-3 from Claopodium crispifolium (Hook.) Ren. & Card. and Anomodon attenuatus Hueb., or an associated actinomycete, and ohioensins and pallidisetums from Polytrichum spp. Several hundred collections, which have been obtained from temperate regions of North America during 1990 and 1991, are currently being screened in new bioassays; active sesquiterpene lactones have been recently isolated from species of Porella. The methodologies of collecting and screening bryophyte samples are discussed with consideration to costs based on expected number of samples that might be collected in a day, the diversity in the collections as related to phytogeography and vegetation types, and the bryophyte cover that is vanishing in many forest regions of the United States. The difficulties in obtaining large collections for isolation of active agents are also discussed by examplerecollection of Claopodium crispifolium

The CPI for rents: a case of understated inflation

Until the end of 1977, the U.S. consumer price index for rents tended to omit rent increases when units had a change of tenants or were vacant, biasing inflation estimates downward. Beginning in 1978, the Bureau of Labor Statistics (BLS) implemented a series of methodological changes that reduced this nonresponse bias, but substantial bias remained until 1985. The authors set up a model of nonresponse bias, parameterize it, and test it using a BLS microdata set for rents. From 1940 to 1985, the official BLS CPI-W price index for tenant rents rose 3.6 percent annually; the authors argue that it should have risen 5.0 percent annually. Rents in 1940 should be only half as much as their official relative price; this has important consequences for historical measures of rent-house-price ratios and for the growth of real consumption.Consumer price indexes ; Rent ; Inflation (Finance)

The CPI for rents: a case of understated inflation.

Until the end of 1977, the method used in the U.S. consumer price index (CPI) to measure rent inflation tended to omit rent increases when units had a change of tenants or were vacant. Since such units typically had more rapid increases in rents than average units, this response bias biased inflation estimates downward. Beginning in 1978, the Bureau of Labor Statistics (BLS) implemented a series of methodological changes that reduced response bias but substantial bias remained until 1985. We set up a model of response bias, parameterize it, and test it using a BLS microdata set for rents. We conclude that from 1940 to 1985 the CPI inflation rate for rent most likely was understated by 1.4 percentage points annually in U.S. data. We construct an improved rental inflation series for 1940 to 2000; at the starting point in 1940, the revised index is 54 percent as large as the official CPI.Consumer price indexes ; Rent ; Inflation (Finance)

Measuring American rents: a revisionist history.

Until the end of 1977, the method used to measure changes in rent of primary residence in the U.S. consumer price index (CPI) tended to omit price changes when units changed tenants or were temporarily vacant. Since such units typically had more rapid increases in rents than average units, omitting them biased inflation estimates downward. Beginning in 1978, the Bureau of Labor Statistics (BLS) implemented a series of methodological changes that reduced this bias. The authors use data from the American Housing Survey to check the success of the corrections. They compare estimates of the historical series adjusted for the BLS changes in methodology with a new hedonic estimate of changes in rental rates. The authors conclude that from 1940 to 1977 the CPI for rent would have been about 60 percent higher if current BLS practices had been used – between 1.3 and 3.5 percentage points. Even after the corrections have been made, the authors' hedonic estimates suggest that the current CPI methodology may still understate the rental inflation rate by one-half to 1 percentage point.Rent

Scaling function and universal amplitude combinations for self-avoiding polygons

We analyze new data for self-avoiding polygons, on the square and triangular lattices, enumerated by both perimeter and area, providing evidence that the scaling function is the logarithm of an Airy function. The results imply universal amplitude combinations for all area moments and suggest that rooted self-avoiding polygons may satisfy a $q$-algebraic functional equation.Comment: 9 page
