REGIONAL AGRICULTURAL PRODUCTION SYSTEMS: ESTIMATES FOR WESTERN AUSTRALIA

A regional model, be it computable general equilibrium or partial equilibrium in construct, which is based on the national parameters would certainly provide misleading results if the regional economy or sector is significantly different from its national counterpart. For a credible and useful quantitative analysis of the regional impacts of changes in, say, government policies or international events, one thus needs an empirically based economic model that reflects the key features of the regional economy or sector concerned. This is the motivation for this paper, which estimates a disaggregated agricultural production system for Western Australia (WA): a key farming State of Australia. The paper uses a profit function approach that explicitly recognizes jointness in agricultural production and various climatic zones in WA, and an estimation procedure that involves the Diewert–Wales decomposition technique. It presents estimates of elasticities of supply responses and input demands in WA agriculture, and compares these with the national estimates.     

GREENHOUSE GAS EMISSIONS AND ECONOMIC STRUCTURE IN URUGUAY

Using input–output analysis, we identify the key sectors in greenhouse gas (GHG) emissions of the Uruguayan economy. The responsibilities of each sector in terms of its emissions are decomposed into an own component, generated during the activities of the sector, and an indirect component, generated by the induced activities in other sectors. This has important implications for the design of mitigation polices, as the appropriate policy measures are contingent on the nature of the pollution. Technical improvements and best practices are effective only when applied to directly polluting sectors, while demand policies may be more appropriate for indirectly polluting sectors. In addition, we analyze pollution generated during the production of exports. The results show that demand policies are going to be effective in the Building, the Hotel and restaurants, and the Wholesale and retail trade; and repair of motor vehicles and motorcycles sectors. These policies complement GHG emissions’ mitigation policies in directly polluting sectors (mainly the Cattle farming and the transport-related sectors). Finally, methane and nitrous oxide emissions are mainly the consequence of production for exports, while carbon dioxide emissions are mainly driven by production for domestic consumption.     

SLUM DWELLERS' HOUSEHOLD CONSUMPTION PATTERN AND ITS IMPLICATION FOR COST RECOVERY IN SLUM UPGRADING: Evidence from Dhaka, Bangladesh

Strong emphasis has recently been placed on recovery of improvement costs from slum dwellers for sustainable development of low-income urban settlements. Furthermore, socio-economic stratification of slum dwellers is perceived to influence their consumption and investment patterns in the city. Against this background, populations in six slums in Dhaka, stratified into house owners and renters, were studied. Results show that renters have stronger ties with their rural origin where they are likely to return and remit a significant portion of their income, leaving a limited amount for consumption and investment in the city. In contrast, owners have stronger attachment to the city, remit negligible amounts to their village of origin and pay more attention to city consumption and investment. Consequently, any cost recovery approach to slum upgrading implies heavy reliance on owners. But renters can also be expected to share the cost, to some limited extent, in the form of property tax or community services charges. The key point here is the concurrence of renters and owners on the sharing of costs and benefits.     

CENTRAL LIMIT THEORMS IN C[0,1] FOR A CLASS OF ESTIMATORS OF A DISTRIBUTION FUNCTION

As non–parametric estimates of an unknown distribution function (d.f.) F based on i.i.d. observations X ₁ X_n with this d.f.

are used, where H _n is a sequence of d.f.'s converging weakly to the unit mass at zero. Under regularity conditions on F and the sequence ( H _n) it is shown that √_n( F _n– F ) and √_n( R _n – F ) in C [0,1] converge in distribution to a process G with G( t ) = W° ( F ( t )), where W ° is a Brownian bridge in C [0,1]. Further the a.s. uniform convergence of R., is considered and some examples are given.

COINTEGRATION AND CHANGES IN REGIME: THE JAPANESE CONSUMPTION FUNCTION

In this paper we examine a model of cointegration where long-run parameters are subject to switching between several different cointegrating regimes. These shifts are allowed to be governed by the outcome of an unobserved Markov chain with unknown transition probabilities. We illustrate this approach using Japanese data on consumption and disposable income, and find that the data favour a Markov-switching long-run relationship over a standard temporally stable formulation. © 1997 by John Wiley & Sons, Ltd.     

ECONOMIC SANCTIONS: FAILED FOREIGN POLICY TOOL AND A COST TO AMERICAN BUSINESS

In recent years the US government has increased its use of economic sanctions in order to punish countries, organisations and individuals. This form of foreign policy has become an increasing burden on US business and adversely affects US competitiveness and perceived reliability in the global marketplace. In addition, economic sanctions are generally ineffective in producing the desired changes and often harm the people they were intended to help. This paper argues that economic sanctions are an increasing menace to US business, represent an ineffective tool of foreign policy, and do not meet generally accepted ethical standards.     

THE INDICATOR FUNCTION: A USEFUL DEVICE FOR DETERMINING CERTAIN MINIMAL SUFFICIENT STATISTICS

An elegant technique for obtaining minimal sufficient statistics in the case of families of distributions with support depending on the paramaters, is exposed.     

IS THERE A CONFLICT BETWEEN COMMERCIAL GAIN AND CONCERN FOR THE POOR? EVIDENCE FROM PRIVATE SCHOOLS FOR THE POOR IN INDIA AND NIGERIA

In many developing countries, private unaided schools are serving the poor in large numbers. Some commentators view their presence as undesirable - in particular assuming that there is a conflict between'commercial gain' and 'concern for the poor'. We show one way in which there is no conflict - the private unaided schools offer free or concessionary places to the poorest of the poor. Using data from a random sample of schools in Hyderabad, India, and a smaller sample in Makoko, Nigeria, we show that such places range from 10–20% of all places offered.     

ARGUING FOR LIBERTY IN A SECULAR AGE

This article reviews Michael Levin's philosophical argument that minimal government is necessary and that, by the same reasoning, more‐than‐minimal government is unnecessary. Levin's argument does not appeal to any concept of rights, so can easily be used with those for whom rights‐based arguments require belief in a transcendent deity.     

ON BOOTSTRAPPING A CLASS OF DIFFERENTIABLE STATISTICAL FUNCNONALS WITH APPLICATIONS TO L– AND M– ESTIMATES

EFRON'S (1979) "bootstrap" method is justified for a class of differentiable statistical functionals which includes many L – and M –statistics. For illustration, a Monte Carlo study for the trimmed means is also included.
