Inclusion of Environmental Goods in National Income Accounting

National income statistics take into account the values of market goods and completely ignore the environmental goods. The purpose of this paper is to suggest the integration of environmental goods into the framework of Leontiefs input–output analysis. It is suggested that environmental goods, such as clean air, fresh water, quiet, etc., be treated as sectors in the same way as market goods sectors. The final deliveries of the sectors may be positive, zero or negative, depending on the scarcity of the environ mental goods and political decisions. The paper gives a numerical illustration of how the environmental goods can be valued from an input–output analysis. It is recommended that a system should be devised to adjust the national income estimators of individual countries for the changes in the environmental goods caused by the economic activities of these countries.     

The desegregating effect of school tracking

This paper makes the following point: “detracking” schools, that is preventing them from allocating students to classes according to their ability, may lead to an increase in income residential segregation. It does so in a simple model where households care about the school peer group of their children. If ability and income are positively correlated, tracking implies that some high income households face the choice of either living in the areas where most of the other high income households live and having their child assigned to the low track, or instead living in lower income neighbourhoods where their child would be in the high track. Under mild conditions, tracking leads to an equilibrium with partial income desegregation where perfect income segregation would be the only stable outcome without tracking.

环境—经济导向的企业环境收入与成本分析

随着环境问题的日益突出和建立集约型经济增长模式的要求,环境保护日益受到重视,环境问题对企业生产经营、投资决策和业绩评价等产生的影响也越来越大。为了适应新形式下管理的要求,企业应当建立环境—经济导向战略管理模式和核算体系。与环境有关的收入与成本使企业的传统的收入与成本的内涵和外延发生变化,传统的会计核算已不能全面反映企业的经济业绩和环境业绩。为了更全面地反映企业与环境有关的收入与成本信息,本文对企业环境—经济导向的环境收入与成本的概念及类别的界定、确认、计量与信息披露进行了探讨。     

Modelling low income transitions

We examine the determinants of low income transitions using first‐order Markov models that control for initial conditions effects (those found to be poor in the base year may be a non‐random sample) and for attrition (panel retention may also be non‐random). The model estimates, derived from British panel data for the 1990s, indicate that there is substantial state dependence in poverty, separate from persistence induced by heterogeneity. We also provide estimates of low income transition rates and lengths of poverty and non‐poverty spells for persons of different types. Copyright © 2004 John Wiley & Sons, Ltd.     

Effects of international sharing of pollution abatement burdens on income inequality among countries

Improvements in environmental quality will boost output production and hence economic growth. However, although environmental abatement equally benefits all economies in the world, it is shown that, if the private productive resources are not yet accumulated sufficiently in low income economies, income inequality among economies can be widened in the short term not only under equal burden sharing of pollution abatement but even under income-proportional burden sharing. When the marginal productivity is diminishing, the negative effect of the burden is large relative to the positive effect of the improved environment in economies in which resources are not accumulated sufficiently.     

Social Welfare and Income Inequality in a System of Cities

This paper develops a general-equilibrium model of a system of core-periphery cities to examine the main determinants of intra- and inter-regional income disparities. The economy is populated by a continuum of (homogeneous) unskilled and (heterogeneous) skilled workers. Unskilled workers, whose wages are determined competitively, specialize in food production in local cities; skilled workers, whose wages are determined according to a Nash bargain, manufacture a high-tech commodity in the metropolis. We establish conditions under which this core-periphery equilibrium spatial configuration emerges. We show that both intra- and inter-regional income disparities are present; the determinants of each type of disparity and the social-welfare implications are fully investigated. Our results suggest that public policy programs that improve income equality may not be necessarily welfare enhancing.     

Impact of the food stamp program on selected food nutrients purchased by low income households

The objective of this paper is to test the hypothesis that the food Stamp Program (FSP) improves the nutritional status of the low income households, particularly, in the southern region of the United States. Empirical results are obtained via application of the Box-Cox transformation technique to sample data developed from the Bureau of Labor Statistics 1972–1973 Consumer Expenditure Diary Survey. The relatively small income elasticities suggest that policies aimed at generating nutritionally adequate diets through income transfers may not be as effective as the FSP in improving the nutritional status of low income households. Analyses of the impacts of other socio-economic variables suggest that some pattern of nutrient purchasing behavior are evident over different stages of household life cycle. Furthermore, race of household and level of educational attainment of the homemaker are found to have significant effects on the purchase of selected nutrients.     

Output complexity, environmental conditions, and the efficiency of municipalities

Over the last few years, many studies have analyzed the efficiency of local governments in different countries. An accurate definition of their output bundles—i.e., the services and facilities they provide to their constituencies—is essential to this research. However, several difficulties emerge in this task. First, since in most cases the law only establishes the minimum amount of services and facilities to provide, it may well be the case that some municipalities go beyond the legal minimum and, consequently, might have an uncertain effect on efficiency when compared to other municipalities which stick to the legal minimum. Second, municipalities face very different environmental conditions, which raises some doubts about the plausibility of an unconditional analysis. This study tackles these problems by proposing an analysis in which the efficiency of municipalities is evaluated after splitting them into clusters according to various criteria (output mix, environmental conditions, level of powers). We perform our estimations using order-m frontiers, given their robustness to outliers and immunity to the curse of dimensionality. We provide an application to Spanish municipalities, and results show that both output mix and, more especially, environmental conditions, should be controlled for, since efficiency differences between municipalities in different groups are notable.     

The future's poor: Projecting the population eligible for federal housing assistance

Microanalytic simulation techniques are used to show that, under a reasonable set of assumptions, the real income of elderly households can be projected to grow at a rate higher than that of other population groups over the next several decades. Simulation modeling also shows that current low marriage and fertility rates and high divorce rates, if continued, will lead to a future population that is proportionately more elderly and of smaller average family size. A number of federal, state, and local assistance programs restrict eligibility to low-income households. In an application to the major federal housing assistance program, it is shown that future growth in the number of elderly households may well be offset by their relatively high income growth, leaving the proportion elderly among those eligible for assistance essentially unchanged over the next 40 years. The findings imply that future changes in the demographic composition of the U.S. population may not be reflected in the composition of the low-income population. This possibility should be considered in planning assistance programs targeted on the poor.     

Joint production national income definitions and pricing in linear environmental models

Economic activity is explicitly modelled as a set of joint production processes encompassing the generation of environmental pollution. Particular results of Leontief, generalized by Lowe, which would finance environmental protection through a number of tax or pricing schemes, are shown to be inconsistent with strictly correct definitions of national income. Qualified use of linear joint production environmental models is accepted, where these use efficiency prices and recognize data limitations. Such models can aid understanding of the costs, in terms of other goods and services foregone, of attaining particular standards of environmental protection.     

Challenges in designing,implementing and operating an environmental management system

Introducing an effective environmental management system (EMS) to an organization is a complex process. This complexity is belied by current EMS models that concentrate on EMS frameworks and components, and present a relatively simple approach to the process, especially the introduction and implementation phases. While these models outline what should be introduced, they provide little guidance on how EMSs may be implemented. Experience indicates that effective EMS introduction may be adversely affected by a number of conditions, but EMS literature has yet to recognize these barriers. There is a significant gap between EMS theory and application. This paper discusses the degree to which current EMS models address practical EMS design and implementation, barriers to successful EMS introduction, strategies and tactics for overcoming these barriers and implications for EMS practice.

Greening Displacements,Displacing Green: Environmental Subjectivity,Slum Clearance,and the Embodied Political Ecologies of Dispossession in Mumbai

In Indian cities, informal ‘slum’ settlements have long been targeted for removal as an environmental improvement strategy, despite their relatively low impact. Slum clearance has escalated with the combination of speculative development and environmental change, creating uneven precarity throughout Mumbai's neighborhoods. State agents play a direct role in slum evictions, but they do not act unilaterally. Diverse lower‐income and middle‐class residents seeking better living conditions have sometimes converged in their embrace of slum clearances and resettlements that advance elite development interests. In other moments, the dispossessing effects of market‐based and elite‐biased slum rehabilitation have fomented contestation. This article analyzes how differently situated groups emerge as ‘environmental subjects’ that embrace or contest improvement projects. It suggests three dimensions of subject formation: governing logics and discourses of urban environmental improvement, the territorial politics of informality, and differentiated embodied experiences of precarity and dispossession. Environmental subject formation is explored through two interventions that entail slum clearance—mangrove and green space conservation and an urban transport infrastructure project. Findings suggest that the connection between displacement and improvement cannot be explained through theories of environmental gentrification but require attention to the simultaneously inclusive and dispossessing regimes of postcolonial development.     

On the Economics and the Politics of Environmental Protection

A bstract . TWO loci of discussion respecting national policies for environmental protection are synthesized. Most economic discussions are couched in terms of analytical measurements of the social benefits and costs of different policies. But most political science discussions are couched in terms of the procedural obstacles to implementation erected by special interest groups. The standard tool of marginal cost/benefit analysis is applied to reveal how the redistribution of real income among distinct special interest groups determines the extent to which those groups align themselves politically. Many of the apparent conflicts among policy objectives in the area of environmental protection, full employment , and an acceptable distribution of income , can be mitigated by means of a carefully designed program of selective law enforcement and tax-financed subsidies.

A Spatial Modelling Framework for Income Estimation

Abstract

The main aim of this paper is to provide a spatial modelling framework for income estimation through the application of a contemporary spatial analysis technique. The application refers to the modelling of mean recorded household income in the area covered by the postcodes of the municipality of Athens in 2001. The main findings suggest that there is a very strong relationship between the proportion of people with a postgraduate qualification (namely, a Master's degree or PhD) and mean household income. Furthermore, there is evidence that this relationship is not stationary across space. This finding allows a better understanding as well as modelling of the main determinants of income in Athens.     

Beyond a Livable and Green Neighborhood: Asserting Control,Sovereignty and Transgression in the Casc Antic of Barcelona

During the past 15 years, the Casc Antic, a traditionally low‐income and immigrant neighborhood in Barcelona, has been the site of community‐based mobilization to revitalize abandoned areas and improve local environmental conditions. The organization of residents and their supporters is situated within a broader context of urban political and socioeconomic change — the transformation of the urban economy into a decentralized, global and technology‐ and service‐focused system, accompanied by rising socioeconomic inequality and displacement in inner‐city areas. To date, few studies in the urban environmental arena have been placed within processes of urban change and offer specificity on the purposes, intents and goals that poor and minority residents develop as they understand, resist and challenge their marginality. Why do residents of marginalized neighborhoods and their supporters organize to proactively improve livability and environmental quality? To what extent do the environmental struggles of marginalized communities serve as means to advance more complex political agendas in the city? Through the examination of neighborhood organization for livability in the Casc Antic, I analyze how activists use their environmental endeavors as tools to address stigmas attached to their place, control the land and its boundaries, and build a more transgressive form of democracy.     

Solving the liquidity constraint by options on futures

The aim of this paper is to show that an option on futures may solve the liquidity constraint problem. I consider a consumer (or an investor) who wishes to discount her future income in order to finance her present consumption (investment). Under asymmetric information, such an agent may incur a liquidity constraint (credit rationing). However, the optimal constrained consumption, as a function of future income, resembles a short position of a put option written on future income. This implies that allocating savings to a long call option position on futures may restore the unconstrained relationship between the optimal present consumption and future income. The option on a futures contract is constructed so that the (future) agent’s income is correlated with some futures contract (but this is private information) on which the option is issued. The allocation of savings of the borrower to the option on futures turns out to be financially beneficial compared to the allocation of savings to the risk-free investment.     

Natural inequality,production and economic growth

This paper explains why the effect of income inequality on productivity and growth is ambiguous. When income distribution exhibits inequality levels that are compatible with accepted criteria, productivity and growth ensue. When the divergence from an acceptable level of inequality occurs, then under certain conditions, we may expect lower (higher) production levels and lower (higher) levels of economic growth.
