A COMPARATIVE ANALYSIS OF AGRICULTURAL TRACTOR INVESTMENT MODELS AgEcon
Vanzetti, David; Quiggin, John C..
An implicit rental price approach is used to analyse the determinants of farm tractor investment at the aggregate level. Three models, based on different assumed factor substitutabilities, are compared. Variations in the rental price of tractors appear to have less effect on demand than variations in factors affecting the profitability of the cropping enterprise as a whole. The implications for forecasting and for policy instruments, such as the investment allowance, are discussed.

A Note on the Use of a Logarithmic Time Trend AgEcon
Watts, Geof; Quiggin, John C..
It is shown that parameter estimates in a regression with a logarithmic time trend are not invariant to the choice of the starting point of that time trend. Possible solutions to this problem are discussed and applied to data from a recent article in this Review where a logarithmic time trend was included. It is suggested that the appropriate course is either to estimate the starting date directly or to adopt a functional form invariant to the choice of starting date.

Climate change and climate uncertainty in the Murray-Darling Basin AgEcon
Adamson, David; Mallawaarachchi, Thilak; Quiggin, John C..
Human activity has modified the environment at all scales from the smallest ecosystems to the global climate systems. In the analysis of the Murray-Darling Basin, it is necessary to take account of effects of human activity ranging from local changes in water tables and soil structure through basin-level effects of the expansion of irrigation to changes in precipitation pattern arising from the accumulation of greenhouse gases in the atmosphere. In this paper, we analyse the impact of, and adjustments to, climate change in the Murray-Darling Basin, using a simulation model that incorporates a state-contingent representation of uncertainty.

COMMON PROPERTY, PRIVATE PROPERTY AND REGULATION THE CASE OF DRYLAND SALINITY AgEcon
Quiggin, John C..
The term 'common property' has frequently been misapplied to situations where no property rights exist. Common property rights have provided a workable alternative to private property in many historical situations. Common property concepts and institutions can also play a major role in analysing and responding to current environmental problems. In this paper, the problem of dryland salinity is examined and solutions based on common property, private property and regulation are compared.

CONTRADICTORY PREDICTIONS ON SUPPLY RESPONSE UNDER STABILIZATION: A RECONCILIATION AgEcon
Quiggin, John C..
Two separate bodies of literature on stabilization give radically different results, yet these contradictions have not attracted any attention. The first arises from the neoclassical theory of stabilization and predicts that beneficial stabilization will always attract positive supply response. The second arises from the work of Newbery and Stiglitz and predicts 'perverse' supply response for highly risk averse producers. In this paper, the differences which yield these results are described and some suggestions are made for a generalized model.

Costs of adjustment to climate change AgEcon
Quiggin, John C.; Horowitz, John K..
The present paper argues that the costs of climate change are primarily adjustment costs. The central result is that climate change will reduce welfare whenever it occurs more rapidly than the rate at which capital stocks (interpreted broadly to include natural resource stocks) would naturally adjust through market processes. The costs of climate change can be large even when lands are close to their climatic optimum, or evenly distributed both above and below that optimum.

Discounting and Sustainability AgEcon
Quiggin, John C..
The discounting of future benefits has long been one of the most controversial, and in many ways, unsatisfactory, aspects of benefit -cost analysis. This concern has been heightened by the rise of the environmental movement and, particularly by the debate over sustainable development. The sustainability approach is presented as an alternative to the standard benefit-cost analysis approach to the question of inter-generational equity. Sustainability is in fashion, and, as with all fashionable terms, it has been used in many ways and in support of many different policy agendas. A summary and critique of the literature is given by Ule (1991). I shall interpret sustainability very broadly to encompass two main concerns: (i) The interests of future...

Drought policy: a graphical analysis AgEcon
Quiggin, John C.; Chambers, Robert G..
The standard approach to modelling production under uncertainty has relied on the concept of the stochastic production function. In the present paper, it is argued that a state‐contingent production model is more flexible and realistic. The model is applied to the problem of drought policy.

Environmental economics and the Murray-Darling river system AgEcon
Quiggin, John C..
Much concern about the negative environmental consequences of agricultural development in Australia, including salinisation, waterlogging and algal blooms, has focused on the problems of the Murray–Darling Basin. The aim of this article is to provide an overview of the environmental problems of the Murray–Darling Basin from an economic perspective, and a selective survey of the relevant economic literature, including theoretical analysis, modelling and contributions to the development of water policy. In attempting to understand the complex problems of the Murray–Darling Basin, an eclectic approach drawing on externality, sustainability and property rights perspectives seems most appropriate.

Fiddling while carbon burns: why climate policy needs emission pervasive pricing as well as technology promotion AgEcon
Pezzey, John C.V.; Jotzo, Frank; Quiggin, John C..
Effective climate policy requires global emissions of greenhouse gases to be cut substantially, which in energy sectors can be achieved by lower emissions supply technologies, greater energy use efficiency, and substitution in demand. For policy to be efficient requires fairly uniform, pervasive emission pricing from taxes, permit trading, or hybrid combinations of the two, as well as significant government support for low-emission technologies. We compare the kind of technology-focused climate policies currently adopted by Australia and the USA, the ‘'Asia-Pacific Partnership on Clean Development and Climate'’ (AP6), against this ideal policy yardstick. We find they omit the need for emission pricing to achieve abatement effectively and efficiently; they...

Grandfathering and greenhouse: the role of compensation and adjustment assistance in the introduction of a carbon emissions trading scheme for Australia AgEcon
Menezes, Flavio; Quiggin, John C.; Wagner, Liam.
The terms ‘grandfather clause’ and ‘grandfathering’ describe elements of a policy program in which existing participants in an activity are protected from the impact of regulations, restrictions or charges applied to new entrants. In this paper, the role of grandfathering in the design of a carbon emissions trading scheme in Australia is assessed. It is argued that adjustment assistance policies such as those adopted in conjunction with previous microeconomic reform programs are preferable to policies based on the free issue of emissions permits.

LABOUR SUPPLY AND OFF-FARM WORK BY FARMERS: THEORY AND ESTIMATION AgEcon
Robinson, Chris; McMahon, Pat J.; Quiggin, John C..
Off-farm employment has become increasingly important as an aspect of resource adjustment and a source of income in Australian agriculture. However, it is surprising that there is a paucity of work on this topic reported in the agricultural economics literature. Therefore, we have drawn upon recent developments in labour economics in order to investigate off-farm employment in Australia. A conceptual model of the allocation of a farmer's labour between farm and off-farm work is developed and applied to cross-sectional data from the Australian Agricultural and Grazing Industries Survey. A Tobit maximum likelihood procedure is utilised to test the influences of the life cycle, level of human capital, wealth, non-wage income and farm income on the off-farm...

Modelling socially optimal land allocations for sugar cane growing in North Queensland: a linked mathematical programming and choice modelling study AgEcon
Mallawaarachchi, Thilak; Quiggin, John C..
A modelling framework is developed to determine the joint economic and environmental net benefits of alternative land allocation strategies. Estimates of community preferences for preservation of natural land, derived from a choice modelling study, are used as input to a model of agricultural production in an optimisation framework. The trade‐offs between agricultural production and environmental protection are analysed using the sugar industry of the Herbert River district of north Queensland as an example. Spatially‐differentiated resource attributes and the opportunity costs of natural land determine the optimal trade‐offs between production and conservation for a range of sugar prices.
