Wages and Unemployment in Australia*

This paper reviews various models that may be used to analyze the inflation-unemployment problem in Australia. The focus is on the unemployment problem, rather than on inflation, and on the role of wages, nominal and real, in affecting this problem. Models discussed include the Popular Keynesian, Phillips Curve, Fixed Coefficient and Neoclassical Models. The possibility of increasing returns is considered. Australian evidence bearing on the appropriateness of these models is discussed. The effect of demand expansion on the exchange rate and hence real wages is stressed. Some emphasis is placed on the concept of ‘union-voluntary’ unemployment. At the end possible solutions to the unemployment problem are summarized.     

Money Wages, Consumer Prices, and Causality in Australia*

This paper exploits recently developed statistical techniques to examine the causal patterns in lag relationships between changes in wages and consumer prices. The analysis uses quarterly data for selected periods and a total historical sample period 1954-82. Causation has generally been unidirectional from wages to prices. However, for the first half of the 1970s bidirectional causation was detected, though the causation from wages to prices was statistically more significant. Brief consideration is given to some policy implications of the results.     

A Note on Causality Between Money,Wages and Prices in Australia*

Lead and lag relationships between money, wages. and prices are examined using Australian data. Granger causality tests support univariate causality running from money to both wages and prices. This result is consistent with a monetarist explanation of inflation.     

Skilled Immigration and Wages in Australia*

This paper investigates the impact of the relative growth of skilled migration on the structure of Australian wages. Unlike conventional approaches, the present study uses macro data to examine the response of wages to immigration flows. We use instrumental variable techniques to control for the potential endogeneity of immigration. The results, using alternative estimation strategies, are consistent with the dominant findings from existing empirical work. There is no robust evidence that a relative increase in skilled immigrants exerts any discernible adverse consequences on the wage structure in Australia.     

Optimising Agents, Staggered Wages and Persistence in the Real Effects of Money Shocks

In this paper we incorporate Taylor's (1979) staggered wage setting into an optimising dynamic general equilibrium framework to study whether staggered wages could induce a high degree of persistence in the real effects of money shocks. We conclude that high persistence is an unlikely outcome. Sensible values of the microeconomic parameters and/or a moderate rate of underlying inflation imply a low degree of persistence. Furthermore, once explicit microfoundations are taken into account, we show that: (i) the model is highly non-linear; (ii) the inertia of the system is inversely related to the level of average inflation.     

Equilibrium Unemployment in Australia: Concepts and Measurement*

This paper reviews some concepts of equilibrium unemployment and outlines the fundamental difficulties facing any attempt to produce estimates of the equilibrium rate of unemployment. It develops simple quasi-reduced form models of aggregate unemployment based on rival non market-clearing and market-clearing theories. These equations form the basis of an empirical model of aggregate unemployment in Australia since 1969. The empirical evidence suggests that most of the observed increase in unemployment can be attributed to cyclical rather than structural-frictional factors. However, stylized explanations of cyclical unemployment exclusively along the lines of Keynesian, Classical or equilibrium search theory are found inadequate.     

Unemployment in Australia: Duration and Recurrent Spells*

Using a parametric technique. this paper estimates average completed duration of unemployment for several age and sex categories. It shows that the use of Labour Force Survey data leads to underestimates due to the presence of recurrent unemployment. When allowance is made, using A BS Persons Looking for Work and Labour Force Experience data, it is shown that new entrants to unemployment in 1981 could expect to remain unemployed for nearly six months. For teenagers evidence is presented to suggest that, contrary to current economic thought, teenagers may on average be unemployed for longer periods per spell and may have less experience of recurrent spells than their counterparts. It also shows that changes in the unemployment rate are dominated by changes in duration.     

Trade and Real Wages: a Macroeconomic Model*

We offer a new paradigm to understand the effects of trade on factor rewards. It utilizes the classical‐Keynesian model, and shows that normally a country’s trade deficit hurts labor by lowering the real wage, but benefits the owners of capital. The effects of tariffs on factor rewards and employment are opposite to those of the trade deficit, which falls with a rise in the tariff rate. Countries with trade shortfalls unambiguously benefit from their tariffs, because laborers far outnumber capitalists, who suffer from the declining interest rate. Thus, tariffs lead to a rise in social welfare in trade‐deficit countries.     

Relative Wages and the Changing Industrial Distribution of Employment in Australia*

A simple model is used to analyze the role of changing relative wages in industry labour market adjustment between 1948–49 and 1979–80. Not with standing Australia's highly centralized system of wage determination, it was found that it has permitted modest changes in wage relativities which were generally in the right direction. To the extent that these changes were sufficient to equilibrate the labour market this probably reflects some important changes in the composition of the labour force and the high elasticity of supply from one industry to another.     

Capital Stock, Unemployment and Wages in the UK and Germany

This paper is concerned with the view that capital formation is an important variable in the determination of unemployment and wages in Germany and the UK. Adverse demand shocks affect employment and investment. When shocks reverse, unemployment may not fall to previous levels due to insufficient capital. The empirical results show that unemployment has risen in the last twenty years in both countries due to insufficient investment. Policies that are aimed at stimulating investment may have a permanent effect on unemployment in Germany and the UK.     

Insider Bargaining Power, Starting Wages and Involuntary Unemployment

Recent studies of wage bargaining and unemployment have emphasized the distinction between insiders and outsiders, and that unions act in the interest of insiders. Yet it is typically assumed that insiders and recently hired outsiders are paid the same wage. We consider a model where the starting wage may differ from the insider wage, but incentive constraints associated with turnover affect the form of the contract. We examine under what conditions the starting wage is linked to the insider wage so that increased bargaining power of insiders raises the starting wage and reduces the hiring of outsiders.

Inflation, Unemployment and the NAIRU in Australia

In this paper we investigate the relationship between inflation and unemployment in Australia, post 1959. Our approach is based on identification of the time series components of the data. Evidence is found of significant correlations between the non-trend frequencies of inflation and unemployment and these correlations are exploited to estimate a simple forecasting model that does not suffer from the instability normally associated with the Phillips Curve. Estimates of the NAIRU are also provided and these range from as low as 2.3 per cent to as high as 9.2 per cent over this period, but these estimates are quite imprecise. Reasons for this imprecision are discussed.     

Unit Root Investigation of Greek Real Money Supply and GDP

In this article, the time series of Greek real GDP and real money supply are investigated for the presence of a unit root, allowing for maximum two breaks which take place at an unknown point in time. This methodology is preferred to conventional Dickey & Fuller tests because the covered time horizon, namely from 1858 to 1938, is characterized by a number of very important events, the nature of which is either economic or historical. In addition, time series stationarity is checked through a Kwiatkowski, Phillips, Schmidt, and Shin (KPSS) test.University of Macedonia—Greece. The article was presented at the Fifty-Ninth International Atlantic Economic Conference, London, England, March 9–13, 2005     

Trade, Wages and Unemployment in the Presence of Hiring and Firing Costs

This paper offers a new explanation of the recent Australian wage inequality and unemployment experience. Building on a standard international trade model, it is argued that trade affects wage inequality and unemployment through changes in the bargaining power of different groups of workers in the presence of hiring and firing costs. This allows previously puzzling aspects of the trends to be explained, including the inconsistency of the existing Stolper-Samuelson trade explanation with rising relative skilled wages at the same time as rising skilled labour intensity of production. Considering differences in labour market institutions, in particular hiring and firing costs and minimum wages, allows differences between the experiences of Australia, the USA and Europe to be explained.
