The Relationship between Output and Unemployment with Efficiency Wages

Abstract. We construct a stylised model of the supply side with goods and labour market imperfections to show that an economy can rationally operate at a low-effort state in which the relationship between output and unemployment is positive. We examine data from the G7 countries over 1960–2001 and find that only German data strongly favour a persistent negative relationship between the level of output and rate of unemployment. The consequence of this is that circumstances exist in which market imperfections could pose serious obstacles to the smooth working of expansionary and/or stabilisation policies and a positive demand shock might have adverse effects on employment.     

中国经济中的高增长与低就业——奥肯定律的中国经验检验

对于中国的高速经济增长并没有带来相应的就业增长这样一个经验事实,存在奥肯定律是否有效的问题。我们通过研究认为,单纯验证奥肯定律并不能得出其是否有效的结论。放松其他条件不变的假定,加入其他影响因素的检验结果显示,经济增长与失业率虽然呈现总体上的负向关系,但是经济增长与就业人数增长率也呈现出负向关系,这表明奥肯定律在中国是失效的。因此,我们认为之所以高速的经济增长不能带来持续的就业增长的原因可能是,劳动密集型产业的收入分配中表现出资本密集型产业的特征,而资本密集型产业的收入分配中表现出劳动密集型产业的特征。

A cross-country analysis of the Okun's Law coefficient convergence in Europe

The paper examines whether or not evidence is consistent with convergence of the Okun's Law coefficient (OLC) among several alternative groupings of European economies. A two-step empirical strategy is employed. The first step obtains rolling regression estimates of the OLC for individual European countries. The second step examines how the cross-country variance of the OLC evolves over the decade until 2002 in the selected country groupings. Evidence is found consistent with convergence of the OLC among northern European countries, and among countries with centralized wage bargaining, but an absence of convergence in other country groups.     

Employment, The Labour Force and Unemployment in Australia: A Disagregegated Approach

This article presents statistical analysis of the distributional aspects of labour market developments in the Australian economy from 1966 to 1985. The focus is on the adjustment of the labour force to changes in employment opportunities. Two sets of data for selected age/sex/marital groups are utilised in the analysis: regressions to test for differences in the sensitivity of labour force participation to employment opportunities and a series of tables documenting population adjusted changes in employment and the labour force. The aggregate relationship between employment changes and labour force changes (and hence changes in unemployment) is explained by the disaggregated data.     

Vacancies and Unemployment in Australia

This article examines the extent to which the Mortensen–Pissarides model of labour market search can quantitatively match business cycle fluctuations in Australia. With productivity and job‐separation‐rate shocks, the model fails to produce substantial volatility among unemployment or vacancies, a result similar to Shimer's (2005) findings for the United States. Examining a broader range of shocks significantly increases the magnitude of business cycle fluctuations, but still only explains roughly 25 per cent of labour market volatility. The implied volatility of wages in the model is similar to that in the data and hence excessive wage flexibility is unlikely to be central to the failure of the model as claimed in the literature.     

A generalized Okun's Law: Uncovering the myth of China's labor market resilience

A stable labor market is a policy priority for most countries, especially after the burst of the global financial crisis. Unlike most countries, the labor market in China appears to be holding up well, despite sharp slowdown in economic growth. This paper argues that there are underlying fundamental mechanisms that help explain the resilience of China's labor market. The key to understanding labor market dynamics in China is that rural‐to‐urban migrant flows are more sensitive to growth than urban workers in the process of fast urbanization, which serves as a main shock absorber to buffer employment against adverse shocks. Therefore, we propose a generalized Okun's Law (GOL) that incorporates migrant flows with unemployment rates to capture the relation between labor market dynamics and economic cycles. The original Okun's Law can be regarded as a special case of the GOL for developed countries that have already completed urbanization. Conducting empirical analysis with both China's national‐ and city‐level data and cross‐country panel data, we find strong evidence supporting the GOL theory. Findings in the paper have implications for a deeper understanding of the wisdom of Okun's Law and its application in labor market policies.     

Alleged instability of the Okun's law relationship in Australia: an empirical analysis

The determinants of the long run equilibrium unemployment rate are modelled through a cointegrating regression. The residual term, which represents the error correction mechanism, is used in the testing of a general dynamic model to obtain a simplified representation of the data generation process over the period 1968(2)–1989(2). The long period equilibrium unemployment rate, which is I(1), is shown to be related to the rate of capacity utilization, a structural change variable and the rate of capacity growth. Steady state rates of unemployment are calculated which are based on different assumptions about the magnitudes of the independent variables. In contrast to the other two variables, changes in the rate of capacity utilization are shown to have only modest effects on the steady state unemployment rate. The Okun coefficient is inversely related to the steady state unemployment rate, which accords with intuition. The statistically significant decline in the trend growth rate of non-farm GDP in the 1970s explains, in part, the apparent instability of the Okun's law relationship which is revealed in recent studies. These studies can be criticised for their conometric methodologies.     

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.     

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.

The Relationship Between Environmentally Sustainable Income, Employment and Wages in Australia

The environment is an asset that provides essential services. Like any other asset, its services will diminish as it depreciates. The environmentally sustainable income of a nation depends on a sustained flow of these services, and can be estimated by including the environment in a macroeconomic framework, with a goal to achieve both full employment and sustainability. The relationship of national income to employment is estimated at full employment, actual employment and the employment level that is necessary to maintain sustainable income, for the Australian economy. There proved to be a widening gap between actual income and environmentally sustainable income, and between actual income and income to guarentee full employment. Wage reduction and improvement of technology are analysed as possible ways to meet the goal of an environmentally sustainable income.     

A Threshold Analysis of the Relationship Between Governance and Growth

Abstract

Quality of governance has been found to be significant in economic growth. We investigate, using a threshold technique, whether the quality of governance matters equally across all levels of economic development. We find that the quality of governance is most significant for only a subset of relatively poor countries, while education is most significant for the poorest countries, and region is most significant for the wealthiest.     

The Natural Rate of Unemployment in Australia: Estimates From a Structural Var

The concept of the natural rate of unemployment is widely used in the analysis and discussion of macroeconomic policy. It is, however, unobservable so that estimates of the natural rate are necessarily based on a particular theory of unemployment. Hence, measures of the natural rate, whether constant or time-varying, are necessarily model-dependent. Various series based on specific models have recently become available for Australia. We set out to compute a series for the natural rate based on a minimal theoretical structure captured by a two-variable structural vector-autoregressive (SVAR) model estimated using quarterly Australian data for the period 1978–1997. We assess the robustness of our estimates by varying both the theoretical restriction imposed on the model and the two variables included in the model. We find that the computed natural rate is quite sensitive to model specification, both in terms of the level and of the cyclical behaviour of the natural rate. We argue, however, that a particular variant of our model is strongly preferred to the others investigated. It produces an estimates natural rate series the behaviour of which is broadly consistent with that of series produced by others from more restrictive models.
