Trends in Absolute Poverty in Pakistan: 1990-91 and 2001

Poverty, defined comprehensively as absence of options to shape one’s life according to one’s own preferences, comes closer to the concept of human development as presented in UNDP’s Human Development Reports. Absolute poverty, on the contrary, defines poverty in terms of satisfaction of minimum physical needs of food and non-food items to enable people at the lower end of income distribution to engage in economic activity. From the vantage point of the policy-maker concerned with alleviation of poverty, it is crucial to know the magnitude of the existing level of poverty and identify the policy determinants of poverty as well as constraints standing in the way of an effective attack on the worst forms of absolute poverty. In Pakistan, like many other developing countries, poverty has emerged as a core issue on the policy agenda. The traditional measures of poverty—headcount, severity and poverty gap indicate that the incidence of poverty during the previous decade have shown no sign of poverty abatement despite numerous policy and institutional initiatives undertaken by the government. The debate on trends in poverty during the 1990s—an era of stabilisation and structural adjustment has been wide-ranging in Pakistan. However, there is no consensus on the poverty outcomes from the policy and institutional reforms. Primarily due to non-availability of basic data, the last year for which poverty estimates are available is 1998-99. In view of the need to monitor poverty trends and continuously evaluate the efficacy of policies adopted by the government under the poverty reduction strategy, it is important to evolve a consensus on the use of a consistent poverty line, sources of data and data adjustments for measuring poverty. It is this policy context that has guided us to use a consistent definition of poverty line.

Landlessness and Rural Poverty in Pakistan

Although reducing rural poverty has been the key agenda of economic reforms in Pakistan, the rural poverty continued to rise during the 1990s. The causes of rural poverty are complex and multidimensional. The rural poor are quite diverse both in the problems they face, and the possible solutions to these problems are also different. The paper uses the most recent household data set available—PIHS 2001-02—to examine the causes of rural poverty, as to what accounts for its persistence and what policy measures should be taken to alleviate it. Poverty estimates using official poverty line suggest the high prevalence of rural poverty ranging from 39 percent to 48 percent in all provinces. Rural poverty is found to be strongly correlated with lack of asset in rural areas. The unequal land ownership in the country is found to be one of the major causes of rural poverty, as poverty level was the highest among the landless households followed by non-agriculture households. The incidence of landlessness is common in rural areas. About 67 percent households own no land in the country. Unusually, just 0.3 percent households own 55 and above acres of land across the country, suggesting a highly skewed landownership pattern. Gini Coefficient of landholding suggests that Punjab has the most unequal landownership pattern, followed by the NWFP, Sindh, and Balochistan. The highly unequal land distribution seems to have resulted in tenancy arrangements such as sharecropping, resulting in high prevalence of absolute poverty particularly in Sindh. A broad-based land reform programme, including land redistribution and fair and enforceable tenancy contracts together with rural public works programmes and access to credit, is critical to reducing rural poverty in Pakistan.Poverty, Pakistan

Domestic Terms of Trade and Public Policy for Agriculture in Pakistan

Despite the crucial importance of information on intersectoral terms of trade in the formulation of a host of public policies, the official statistical system in Pakistan is yet to generate a statistical series of the terms of trade for the .agricultural sector on a regular basis. A number of views expressed on Pakistan's agriculture appear to be based either on results of studies that are now outdated, or on a complete neglect of the existing data that could be processed to calculate the terms-of. trade indices. This paper attempts to provide information on the movement of terms of trade for the agricultural sector for the period from 1951-52 to 1983-84. The impact of changes in terms of trade on farm output, distribution of income and efficient use of resources is also traced

Write-limited sorts and joins for persistent memory

To mitigate the impact of the widening gap between the memory needs of CPUs and what standard memory technology can deliver, system architects have introduced a new class of memory technology termed persistent memory. Persistent memory is byteaddressable, but exhibits asymmetric I/O: writes are typically one order of magnitude more expensive than reads. Byte addressability combined with I/O asymmetry render the performance profile of persistent memory unique. Thus, it becomes imperative to find new ways to seamlessly incorporate it into database systems. We do so in the context of query processing. We focus on the fundamental operations of sort and join processing. We introduce the notion of write-limited algorithms that effectively minimize the I/O cost. We give a high-level API that enables the system to dynamically optimize the workflow of the algorithms; or, alternatively, allows the developer to tune the write profile of the algorithms. We present four different techniques to incorporate persistent memory into the database processing stack in light of this API. We have implemented and extensively evaluated all our proposals. Our results show that the algorithms deliver on their promise of I/O-minimality and tunable performance. We showcase the merits and deficiencies of each implementation technique, thus taking a solid first step towards incorporating persistent memory into query processing. 1

Dynamics of Tunneling Centers in Metallic Systems

Dynamics of tunneling centers (TC) in metallic systems is studied, using the technique of bosonization. The interaction of the TC with the conduction electrons of the metal involves two processes, namely, the screening of the TC by electrons, and the so-called electron assisted tunneling. The presence of the latter process leads to a different form of the renormalized tunneling frequency of the TC, and the tunneling motion is damped with a temperature dependent relaxation rate. As the temperature is lowered, the relaxation rate per temperature shows a steep rise as opposed to that in the absence of electron assisted process. It is expected that this behavior should be observed at very low temperatures in a careful experiment. The present work thus tries to go beyond the existing work on the {\it dynamics} of a two-level system in metals, by treating the electron assisted process.Comment: REVTeX twocolumn format, 5 pages, two PostScript figures available on request.

Impact of Infrastructure and Agroclimate on the Location of Rural Bank Branches in Pakistan: A Preliminary Assessment

Rural financial institutions play an important role in development and growth of the agricultural sector. In developing economies some rural areas are adequately served by financial institutions, while others have little or no access to these institutions. This uneven pattern of geographic location of rural bank branches has been attributed largely to regional differences in agroclimatic conditions and infrastructural endowments. We have estimated several alternative specifications which can be helpful in understanding the spatial distribution of commercial bank branches across the rural areas. Our results indicate that the location of rural bank branches is significantly influenced by infrastructural endowments and agroclimatic environment.

Domestic Resource Mobilisation for Development in Pakistan

This paper examines the determinants of private, domestic, and household savings in Pakistan. The analysis shows that private savings can be expected to grow gradually as a result of rising per capita income, falling dependency burden, improved financial deepening, and macro stability. Bivariate causality tests between GNP and savings show that GNP causes both domestic and public savings. However, the causality test is inconclusive in the case of causation between GNP and private savings. This finding has important policy implication in the sense that once a virtual cycle succeeds in accelerating growth, saving would catch up with a lag. In this sense, financing of investment is not a major constraint. The paper underlines the following policy options: (i) a strong effort spread over tax policy (tax reforms as well as tax administration), expenditure restraint, effective expenditure management, and public sector corporate reforms should aim at raising public savings to about 6 percent of the GDP; (ii) the incentives for private savings in Pakistan need to be revamped.
