of this thesis is to contribute to the economics literature by providing a theoretical and empirical investigation of the effects of changes in the relative size of government on Australian economic performance. The theoretical literature indicates that an expansion in government size is likely to induce adverse effects upon economic growth for a host of reasons.
These include the distortionary effects of taxation imposed to finance government expenditures, the displacement effects of private sector economic activity attributable to public sector interventions, and the growth in governmental activity encouraging economic participants to divert their attentions away from direct market activities and towards seeking benefits through the political process. The historical experience suggests that all levels of Australian governments have grown in terms of size and scope of functions and activities undertaken, and that this growth has transpired over a broad range of public policy interventions including expenditure, taxation and revenue-raising and regulation. An assessment of various statistical measurements of public sector size tends to confirm the general proposition that the public sector in Australia has grown over the long run. This thesis analyses the effect of government size on economic performance in Australia using annual time series data for the period 1960 to 2010.
The hypothesis that an increase in the relative size of government leads to a lower per capita economic growth rate is tested using a variety of econometric specifications, including multivariate ordinary least squares and simultaneous equation techniques. The empirical results suggest an increase in government size by ten percentage points is associated with a lower annual GDP per capita growth rate of between 1. This study also reveals the empirical significance of various underlying determinants of public sector growth to overall government size. The increase in public sector service costs relative to the private sector, the greater ease of tax collection attributable to rising female labour market participation, and increasing government expenditures provided as insurance for the effects of economic openness are found to exert significant effects upon growth in public sector size.
However, the empirical results indicate that ‘Wagner’s law’ of increasing government expenditure arising from general economic development does not hold for Australia. 1 Chapter One Introduction ‘A state structure which aligns incentives to minimize predation outperforms economically one that provides incentives for the predation by the powerful over the weak.1 Background A longstanding element of intellectual inquiry within public sector economics concerns trends relating to the size and growth of government activities, the underlying forces that determine changes in government size and scope, and the consequences of growth in the public sector for the performance of economies.1 Macroeconomic events in Australia and other advanced economies of recent years have ensured that these elements of inquiry have transcended the academic economics literature to become a public policy concern of great significance. The so-called ‘global financial crisis’ (GFC), conventionally perceived to have commenced with the collapse of financial institutions such as US investment bank Lehman Brothers in late 2008, was associated with a significant tightening of credit conditions as financial institutions exhibited a greater degree of risk aversion toward corporate and personal lending.2 The onset of significant financial market instability had attendant implications for the macroeconomic performance of numerous economies particularly in the Western world, given the global integration of financial and other markets. Specifically, severe credit constraints detracted from business investments whereas less confident households reduced their consumption expenditures.
These changes contributed to an observed reduction in world trade volumes and industrial production. Although relatively unscathed in economic terms compared with Europe and the United States, Australia was not immune to the impact of a synchronised international economic downturn precipitated by the GFC. According to national accounts data provided by the Australian Bureau of Statistics (ABS), one important measure of economic performance – real gross domestic product (GDP) per capita (in seasonally adjusted terms) - fell by 0.2 per cent in 2008-09 (ABS 2012). The GFC and its associated macroeconomic instability created a political pretext for governments to invoke a suite of unprecedented economic policy measures in the modern era.
These included stringent financial market and corporate regulations, taxpayer-funded financial support for the 1 Unless otherwise specified, the terms ‘government,’ ‘public sector,’ and ‘non-market sector’ will be used interchangeably in this thesis. 2 The underlying causes of the GFC continue to elicit intellectual controversy. One interpretation, usually associated with the Austrian school of economics, points to the dual roles of low official interest rates, and government interventions encouraging mass home ownership, which generated significant economic distortions in the United States the effects of which were subsequently transmitted throughout the global economy (Booth 2009; Horwitz 2009; Kates 2010). 2 financial, manufacturing and other sectors, and Keynesian-style fiscal stimulus policies in an attempt to bolster private sector activity.3 There is little question that such policies have increased the size and scope of the public sector in Australia and the OECD.
However, there remain divergent views regarding the effect of such changes on overall economic activity. One viewpoint is that an increase in public sector expenditure is conducive to improved economic performance.
