The Philippine government intervenes in the domestic rice market through the imposition of import tariffs and the provision of producer and consumer subsidies. While policy makers are aware that these programs come with allocative efficiency costs, they justify the programs on the grounds that...

This 1977 paper is one of several by Alaouze about estimating Armington elasticities for the ORANI model. It postulates that during periods of high demand, domestic producers are unable to supply goods promptly and so purchasers must wait for delivery. The implicit cost of waiting for domestic...

Australian urban transport industries experienced substantial reform during the 1990s leading to significant structural change. Urban transport is typically an important expenditure item for households and structural change in these services may affect households differently depending on their...

Considers the solution of large systems of linear equations, such as those arising from a large linearized economic model. Recommends (a) that matrix inversion be avoided, in favour of LU methods; and (b) that sparsity in the system be exploited using special computer subroutines. Some examples...

In his recent book "Dog Days", Garnaut (2013) argues that the Australian economy faces significant economic challenges, with a risk that just as the investment phase of the mining boom ends, Australia will be entering an economic environment characterised by declining terms of trade, a rising...

This paper describes the application of a detailed labour-supply module, including HIV/AIDS for South Africa. I begin by developing a model of the South African labour market that embodies two salient features of HIV: (1) incidence and transmission rates follow distinct patterns by age, gender,...

Using adjusted 2000 population census data, this paper conducts China's population projections to 2050. Three fertility and four mortality scenarios yield 12 sets of results. Despite the below-replacement fertility, China's population will continue growing for many years. However, there are...

This paper describes the construction of a database that underlies the labour supply module developed for South Africa, with a specific focus on HIV/AIDS. The labour supply theory imposes a stock/flow dynamic mechanism on labour market groups distinguished by labour market activity, age, gender,...

It is possible that water efficiency in irrigation agriculture may improve substantially over the next decade or two. At the same time, worsening agricultural land and water scarcities worldwide may not be matched by agricultural productivity growth. This means that there may be strong growth in...

In this model firms seek to minimise their tax liabilities by purchasing rent-seeking services from a provider who also sells legitimate public services to the government. The provider enjoys economies of scope - its two outputs are produced jointly. Tax reform in this setting can increase both...
