Professor Ross Garnaut, author of the Garnaut climate change review for the federal government, delivered the following speech last night as a part of the University of Melbourne Hamer Oration lecture series:

I am glad of the chance to deliver this oration in honour of Dick and David Hamer, contributors to civilised Victorian and Australian political discourse. Barry Jones once described Dick Hamer as the finest flower of the Victorian Deakinite tradition. That tradition encompassed the ideas that people of goodwill sharing sound knowledge could find the best way through a policy dilemma; and that citizens should be seeking to reconcile competing interests and perspectives, and to strengthen institutions that neutralised extreme viewsby providing opportunities for sound elements in them to be partially absorbed into the mainstream.

Barry Jones had in mind leadership covering a wider field than economic policy, extending into the environment, the arts and humane administration of justice—contrasting sharply with Victorian Governments in times immediately preceding the Hamer years.

These are matters of political culture rather than policy. They have been influential and productive in Victoria and Melbourne, and part of the success of this State and city as civilised polities and communities over more than a hundred years. I focus mainly on economic issues. Today, sound economic policy embraces the environment. To ignore the environmental impact of policies is as economically irrational as to ignore the effects of allowing demand to exceed the productive capacity of the economy, or to ignore distortions which force investment to shift from highly productive to wasteful activities.

I begin by introducing a few basic ideas about means and ends in economic policy in a democratic polity. This is a bit formal, but hopefully will avoid some misunderstandings and save some time later in this presentation. It is a recurring challenge of democratic capitalism to reconcile Government by the people, with its necessary concern for equity, with maintenance of the competition in the market place and the incentives for economising behaviour that are necessary for sustained prosperity. And it is a recurring challenge to reconcile the inevitable accumulation of wealth from success in the market economy, and the influence of wealth in the democratic process, with Government by the people. Compromises that are made and political alliances that are struck in meeting one of the recurring challenges can ease or exacerbate the other.

For the outcome of the political process to be conducive to broadly based prosperity and to the preservation of democratic institutions, there must be knowledge of the effects of various policies; education of the democratic polity in that knowledge; restraint in the use of political power to achieve sectional economic objectives; and restraint in the use of economic power in the political process. A successful democratic polity is built around analysis, public education, tolerance and restraint. The presence of these qualities in the polity allows leaders who are concerned to follow some conception of the public interest to appeal to the democratic electorate over the heads of vested interests, which otherwise have a privileged influential place in the policymaking process.

We now know from much experience and analysis quite a lot about the conditions that must be met for a country’s economic success. To the greatest possible extent, goods and services need to be traded and capital allocated through competitive markets.

There are economic efficiency advantages in labour also being traded through competitive markets, although in this case, democratic rights must constrain the treatment of labour as a commodity. The legitimate debates on regulation of labour markets are about the boundaries between what is conducive to good outcomes for economic efficiency and equitable distribution of material economic benefits, and what is necessary to preserve valuable human freedoms in a democratic polity. The best outcomes for efficiency and equity will give the largest possible role to the market subject to securing the essential democratic freedoms, with budget rather than labour market interventions being used to secure equitable distribution.

The prime role of markets does not mean that the role of Government is incidental to economic success. Far from it. Many services that are essential to good economic performance are provided by Governments or not at all. These services have the characteristics of “public goods”—they cannot be provided efficiently through private markets. In addition, there are activities which generate benefits or impose costs on firms other than the parties to market transactions. Efficient economic outcomes require all such external costs to be taxed or discouraged by regulation, and all such external benefits to be subsidised or encouraged by regulation. One special case of intervention to increase economic efficiency is the increase in aggregate demand to maintain full employment for labour and capital in times of “Depression Economics”.

A second is the internalisation of external environmental costs—now including the important special case of greenhouse gas emissions. Markets do not generate a distribution of income that bears any relationship to what a society considers to be equitable. It is a legitimate and necessary objective of policy in a democratic country with a market economy to intervene to make the distribution of income and wealth more equitable than would emerge from an unconstrained market. The challenge is to achieve the socially desired modification.
