301. Taxes and Tax Reform in Ethiopia, 1990-2003

Author:
Alemayehu Geda and Abebe Shimeles
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
In 1991 the Ethiopian Revolution Democratic Front (EPRDF) toppled the old 'socialist' regime that had ruled the country for seventeen years. In contrast to the previous policy regime of hard control, EPRDF initiated a wide range of reforms that covered not only the tax system but also the exchange rate, interest rates, trade, domestic production and distribution. This pa per attempts to explore the contribution of the tax reform, the change s in its structure and institutional reform in order to understand its role in raising revenue.

302. Consistent Testing for Poverty Dominance

Author:
Bram Thuysbaert and Ricardas Zitikis
Publication Date:
12-2005
Content Type:
Working Paper
Institution:
United Nations University
Abstract:
If uncertainty exists over the exact location of the poverty line or over which measure to use to compare poverty between distributions, one may want to check whether poverty dominance holds. We develop a consistent statistical test to test the null of poverty dominance against the alternative of nondominance. Dominance criteria corresponding to absolute and relative poverty measures are dealt with. The poverty line is allowed to depend on the income distribution. A bootstrap procedure is proposed to estimate critical values for the test. Our results cover both independent and paired samples.

303. The Microeconomics of Inequality, Poverty and Market Liberalizing Reforms

Author:
Rafael E. De Hoyos
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper illustrates how the use of microeconometric techniques can be used to uncover the micro dynamics behind macro shocks. Using Mexican micro data we find out that—controlling for everything else—between 1994 and 1998 returns to personal characteristics in the tradable sector increase d particularly those of skilled labourers. By the year 2000 the positive shock upon the tradeable sector vanishes with returns to personal characteristics converging to the levels observed in the non-tradable sector. We use our model's results to simulate a scenario where the Mexican economy experienced the negative shock of the peso crises in the absence of trade liberalization (NAFTA) and find out that under such a scenario the poverty headcount ratio would have increased more than 2 percentage points above the one observed in 1996. The simulated second- order effect of these changes shows that the skill mixed changed in a way that favoured relatively skilled men and relatively unskilled women. These changes in labour participation and occupation had an overall positive income effect though adverse in distributive terms.

304. Poverty Measurement and Theories of Beneficence

Author:
S. Subramanian
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This note points to certain similarities of orientation and outcome between Derek Parfit's quest for a theory of beneficence and Amartya Sen's quest for a suitable real-valued representation of poverty. It suggests th at both projects, in a certain sense, have been instructive failures. Using Sen's own work, the note also suggests a logically natural way of dealing with some of the problems in poverty measurement reviewed in it—but only to reject this way out on other compelling grounds.

305. The Fiscal Effects of Aid in Ghana

Author:
Robert Osei, Oliver Morrissey, and Tim Lloyd
Publication Date:
09-2005
Content Type:
Working Paper
Institution:
United Nations University
Abstract:
An important feature of aid to developing countries is that it is given to the government. As a result, aid should be expected to affect fiscal behaviour, although theory and existing evidence is ambiguous regarding the nature of these effects. This paper applies techniques developed in the 'macroeconometrics' literature to estimate the dynamic linkages between aid and fiscal aggregates. Vector autoregressive methods are applied to 34 years of annual data in Ghana to model the effect of aid on fiscal behaviour. Results suggest that aid to Ghana has been associated with reduced domestic borrowing and increased tax effort, combining to increase public spending. This constructive use of aid to maintain fiscal balance is evident since the mid-1980s, following Ghana's structural adjustment programme. The pa per provides evidence that aid has been associated with improved fiscal performance in Ghana, implying that the aid has been used sensibly (at least in fiscal terms).

306. Aid and Growth in Sub-Saharan Africa: Accounting for Transmission Mechanisms

Author:
Oliver Morrissey, Karuna Gomanee, and Sourafel Girma
Publication Date:
09-2005
Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper is a contribution to the literature on aid and growth. Despite an extensive empirical literature in this area, existing studies have not addressed directly the mechanisms via which aid should affect growth. We identify investment as the most significant transmission mechanism, and also consider effects through financing imports and government consumption spending. With the use of residual generated regressors, we achieve a measure of the total effect of aid on growth, accounting for the effect via investment. Pooled panel results for a sample of 25 Sub-Saharan African countries over the period 1970 to 1997 point to a significant positive effect of foreign aid on growth, ceteris paribus. On average, each one percentage point increase in the aid/GNP ratio contributes one-quarter of one percentage point to the growth rate. Africa's poor growth record should not therefore be attributed to aid ineffectiveness.

307. Reckoning Inter-group Poverty Differentials in the Measurement of Aggregate Poverty

Author:
S. Subramanian
Publication Date:
09-2005
Content Type:
Working Paper
Institution:
United Nations University
Abstract:
In a heterogeneous population which can be partitioned into well-defined subgroups, it is plausible that the extent of measured aggregate poverty should depend upon the distribution of poverty across the subgroups. A judgment in favour of an equal inter-group distribution of poverty could arise in two ways. In the first approach, equality is upheld as an intrinsic social virtue, and the aggregate measure of poverty, in line with this view, is 'adjusted' to reflect the extent of inter-group disparity in the distribution of poverty that obtains. In the present paper, this approach is examined, with specific reference to the advancement of a diagrammatic aid to analysis called the group poverty profile. In the second approach, equality is upheld for instrumental reasons which arise from the observed fact that any individual's level of deprivation is a function not only of one's own income, but of the general level of prosperity of the group to which one is affiliated. Individual deprivation functions are specialized to a form which reflects this 'group-affiliation' externality, and the resulting poverty measure is studied with respect to its properties, and its implications for inter-group equity. The analysis is briefly extended to a review of the measurement of literacy, along externality-motivated lines suggested elsewhere by Basu and Foster. The paper concludes that social realism in the measurement of deprivation is often compromised by mainstream approaches to economic theorizing in which both heterogeniety and group-related externalities are generally de-emphasized.

308. Innovative Ways of Making Aid Effective in Ghana: Tied Aid versus Direct Budgetary Support

Author:
Peter Quartey
Publication Date:
09-2005
Content Type:
Working Paper
Institution:
United Nations University
Abstract:
There has been significant amount of aid inflow s to developing countries including Ghana, but these have been very volatile. Aid flows have been associated with low domestic resource mobilization and have reduced Ghana to a country heavily dependent on aid. The amount of official development assistance (ODA) inflow s has fallen in recent years and has become unpredictable. It is general knowledge that aid has not yielded the desired benefit. In an attempt to improve aid effectiveness donors have used tie d aid not just to promote commercial interests but also to target aid to particular projects that have direct links with poverty. However, this has not yielded the maximum benefits required. Recently, the government of Ghana and its development partners agreed on an aid package dubbed the multi-donor budgetary support (MDBS), which would ensure continuous flow of aid to finance the government's poverty related expenditures.

309. Poverty and the Welfare Costs of Risk Associated with Globalization

Author:
Ethan Ligon
Publication Date:
09-2005
Content Type:
Working Paper
Institution:
United Nations University
Abstract:
'Globalization' implies change, and uncertainty over future change may affect household welfare. We use data on Lorenz curves over the last fifty years for a sample of 53 (mostly developing) countries. Treating each country-quintile-year as an observation, we first account for variation in consumption expenditures, finding that global shocks are of less importance than country -level shocks in explaining variation in country-quintile consumption growth. While poorer households experience more rapid consumption growth than do wealthier households, they also bear much more risk. However, we find no evidence that this greater risk is related to globalization.

310. Why Do Poverty Rates Differ From Region to Region? The Case of Urban China

Author:
Guanghua Wan and Yin Zhang
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper proposes a semi-parametric method for poverty decomposition, which combines the data-generating procedure of Shorrocks and Wan (2004) with the Shapley value framework of Shorrocks (1999). Compared with the popular method of Datt and Ravallion (1992), our method is more robust to misspecification errors, does not require the predetermination of functional forms, provides better fit to the underlying Lorenz curve and incorporates the residual term in a rigorous way. The method is applied to decomposing variations of urban poverty across the Chinese provinces into three components – contributions by the differences in average nominal income, inequality and poverty line. The results foreground average income as the key determinant of poverty incidence, but also attach importance to the influence of distribution. The regional pattern of the decomposition suggests provincial groupings based not entirely on geographical locations.
