Advocates of public‐private partnerships (PPPs) argue that they can deliver public infrastructure more efficiently than traditional procurement through timelier completion and superior value for money. Despite these claims comparative analysis of the performance of both procurement methods has received scant attention in the PPP literature to date. This paper addresses this issue by providing an in‐depth, case‐based comparison of PPP versus traditional procurement in the schools sector in Ireland. Through detailed semi‐structured interviews with key stakeholders and an examination of the available documentation, we assess whether the key objectives of using PPP have been achieved. Overall, we find no evidence that PPP leads to faster delivery of infrastructure when the overall procurement process from contract notice to delivery is accounted for. In addition, we find only limited evidence to suggest that PPP results in better value for money. 相似文献

In a Malthusian environment, per‐capita incomes are stagnant, meaning they cannot exhibit sustained growth. However, they can still display volatility and persistence when hit by shocks. This article simulates a Malthusian model with realistic life‐cycle structure and stochastic and accelerating growth in land productivity. We find that differences across simulated economies are quantitatively similar to those found in recently compiled data over GDP per capita for several European countries before 1800. This speaks to the relevance of the Malthusian model for understanding preindustrial development in Europe, contrasting with contentions to the contrary in some of the existing literature. 相似文献

The interrelation between changes in the economic structure, i.e., industrial distribution of income and labor force, and the size distribution of income is studied in this paper in a case study of India (1951–1960).
The change in the size distribution of income is the sum of changes due to (1) inter-sectoral factors and (2) intra-sectoral factors. The need for this distinction is emphasized by the result obtained for India, that 85% of the changes in the size distribution may be assigned to inter-sectoral factors, and only 15% to intra-sectoral factors. Since the inter-sectoral factors are significantly influenced by changes in the industrial distribution of income and labor force, our result points out a relation between economic growth and the size distribution which quite often is overlooked in studies of the size distribution.
The results obtained in this paper support several cross-section results of Professor Kuznets. In particular some of these are: (a) inter-sectoral inequality in the economic structure widened with economic growth, (b) the inequality in the size distribution of India widened, (c) the level of inequality in India is higher than in any of the eight developed countries considered. 相似文献

Several recent studies of short-cut estimates comparing real income (on a purchasing power basis) of countries are reviewed, including methods comparing real income based on indicators, like electricity consumption. New estimates are presented for 101 countries which had a tradition of conventional national income estimates in 1965, and for 40 countries without extended national income series. One conclusion from the empircial analysis was that until there exist a large number of countries for which purchasing power estimates of real income are available, it is difficult to discriminate between alternative short-cut methods using indicators, and difficult to estimate real per capita incomes of low income countries without substantial errors of estimate. The paper advocates more purchasing power estimates, and institutionalizing the collection of international prices of specified items so that abbreviated market baskets can be readily compared across countries. 相似文献

Income and expenditure data from 14 countries (representing one-third of the world's population), mostly from the 1970s, are used to construct national income distributions and , after normalizing by purchasing power parities, to construct a "world" distribution of real income. The density of real-income equivalent groups (socio-economic classes) across countries is measured for the "affluent," the "well-off," and the "poor." In comparison with earlier studies, most national distributions of income seem to have been improving, the numbers of those in poverty (based on real income) are lower, and, most important (and disturbing for some) is that the "affluent" class (and those above "middle class" income levels) has (prematurely) swelled in a number of developing countries. 相似文献

This article investigates the role that changes in welfare payments are likely to have on the earnings behavior of homeless persons. Using a cross-sectional random sample of 1,489 homeless persons in Los Angeles, the author analyzes the marginal effect of reducing public transfers on (a) the probability of earning and (b) the level of income from various traditional and nontraditional sources. This procedure allows the author to control for a number of important factors (including background, human capital, and social network variables) that may also influence the probability of earning income. Findings suggest that reducing government benefit income by $100 increases the probability of receiving income from traditional and nontraditional sources by 1.37% and 2.18% respectively. Among the latter are selling items on the streets and "other" (nonspecified) sources. It is concluded that welfare reform measures may in fact create additional societal costs as former welfare recipients turn to alternative forms of income. 相似文献

The trading relationship between a primary-producing South and a manufacturing North has dynamic properties of conflict and symbiosis similar to those of the closed-economy, worker-capitalist relationship. In a simple model these dynamics may lead to cyclical behaviour involving two variables, the Southern share of world income and the rate of exploitation of primary producing capacity. The rate of change of the terms of trade is also cyclical. Long-run income shares are constant, however, implying that the Southern terms of trade rise by just enough to offset productivity savings on primary inputs. 相似文献

The economy of Liberia is one in which, in spite of past satisfactory growth performance, a high level of income inequality persists. In 1977, for instance, a mere 2 percent of the people accounted for some 33 percent of nation-wide wage income. These people live disproportionately in Montserrado County in which the capital city is located. While each of the other counties are largely rural and poor, each has far lower intra-county inequality than wealthy Montserrado.
Intersectoral location of the income-earner, average income levels and the extent of access to human capital formation opportunities are some characteristics of the economy that have been found to explain significant portions of intercounty variations in the levels of household income concentration. Income inequality is reduced with increases in the extent of agricultural activity as the share of the top income group falls and that of the bottom group rises. The reverse happens with growing urban-area activity. Higher income concentration occurs with rising per capita incomes as the top group's income share rises and the bottom income group's share falls. While this appears to be an instance of the Kuznet U-shaped hypothesis, here there are no definite signs of a possible reversal any time soon. The levels of access to educational facilities move inversely with the level of inequality, with expanding elementary facilities benefiting the poorer people at the expense of the wealthy while the reverse happens in the case of expanding secondary educational facilities. 相似文献

This paper analyses the effect of raising effective marginal tax rates on the income of the representative household in each gross income decile in Australia by one percentage point, and distributing the proceeds of the tax increase either in the form of an equal grant, or as an equal payment to members of households in the lower half of the income distribution. The effectiveness of the program in redistributing income is measured as the ratio of total gains in disposable income to households in target deciles to losses in non-target groups, or as the proportional reduction in the poverty gap. The cost is measured as the ratio of the sum of the income-equivalent of changes in the welfare of non-target groups to those of target groups, or as the ratio of income-equivalent losses to gains. 相似文献

We analyze structural changes in the Australian ports and rail freight industries that were driven by microeconomic reform; we find such reforms may generate welfare gains with reduced inequality. We estimate the effects on household income groups of these industry changes by applying a computable general equilibrium model incorporating microsimulation behavior. The structural changes lead to a small increase in household welfare in most regions, with an overall increase of 0.18%, and a small decrease in inequality. Our analysis suggests that policy makers in Australia and other high‐income nations should give serious consideration to microeconomic reform of infrastructure industries.

HOUSEHOLD INCOME PLUS HOUSEHOLD PRODUCTION: THE DISTRIBUTION OF EXTENDED INCOME IN THE U.K. 总被引:1,自引:0,他引:1
This paper provides new estimates of the distribution of extended income amongst non-elderly, one-family households in the U.K. by combining household money income data and valuations of household production time. Extended income is substantially more equal than money income and extending the income definition changes income relativities significantly between families with and without earners and between married couple families and singles. 相似文献
