Persistent unemployment and co-ordination issues: an evolutionary perspective

Abstract. In this paper we look at unemployment as a phenomenon which reflects the co-ordination problems that characterize out-of-equilibrium processes of adjustment. The analysis carried out shifts the focus from structural factors to the economic process. It shows that unemployment cannot be satisfactorily explained – and policy interventions devised – by focusing only on specific characters of the technology or confining the analysis to structural factors concerning the labour market. The co-ordination mechanisms of adjustment processes rather than the fundamentals of the economy appear, in this light, as the main determinants of differences in unemployment trends in different economies; and monetary policy comes back to the center of the stage as an essential element of the working of these mechanisms.

Unemployment, Real Wages and the Money Supply in Australia*

Many observers have attributed the high unemployment experienced in Australia in the 1970s to the rises in real wages which have occurred in the decade. An alternative or additional hypothesis is that unemployment has resulted from policy directed at controlling inflation and that this has been exacerbated by the occurrence of adverse external factors, particularly bul not solely the oil price shocks, which have made inflation more difficult than otherwise to control .
The results of econometric tests suggest that a significant portion of fluctuations in the unemployment rate can be explained by real wage movements, and as well monetary policy through its effects on the real money supply also seems to affect unemployment. Both real wage rises and monetary restrictions appear to have contributed to the jump in unemployment in 1974–75, and since then the continuing high and rising unemployment rate is closely associated with the low growth rate of the real money supply .     

Reworking the Wage Curve: Exploring the consistency of the model across time,space and demographic group

This paper extends Blanchflower & Oswald's (1994) work on the wage curve to the 50 largest metropolitan areas in the United States. The wage curve is more elastic in US metropolitan areas than prior research shows for the nation as a whole, and the wage curve varies over the business cycle, becoming more elastic in periods of higher unemployment. The most striking finding is that black workers have a more elastic wage curve than do white workers. Estimating the wage curve with the non-employment rate, a measure of underemployment, shows elasticities that are substantially higher than for wage curves estimated with the unemployment rate. This trend further increases the negative effects on pay for blacks, who are more likely than white workers to be underemployed.     

Tournaments, minimum wage, and money non-neutrality

To reconstruct the micro-foundation of Keynesian macro-economics, the efficiency wage theory has generally been considered a success in providing a plausible explanation for the existence of involuntary unemployment. However, little has been said about how monetary policy causes fluctuations in aggregate employment and output in the efficiency wage theory. This paper extends Lin and Yang’s [Econ. Inq. 39 (2001) 644] shirking-type efficiency wage model with tournaments to account for money non-neutrality. A distinct feature of our model is that, due to the adoption of tournaments, there will be a hierarchical wage structure rather than a flat wage in the economy. As will be argued, the labor market characterized in this paper is in a sense a reversion to Keynes’ General Theory, but also an improvement upon it.     

Mr Keynes,the Classics and the new Keynesians: A suggested formalisation

Abstract

The paper suggests a new Keynesian model of the General Theory. A reduced form entails a diagram with three curves relating employment and the real wage, which represent the two fundamental classical postulates and the principle of effective demand. This diagram illustrates better than IS–LM the generality of Keynes's theory, clarifying the distinction between voluntary and involuntary unemployment. Other significant features are the role of the distribution of expected interest rates among heterogeneous agents, whether dispersed or concentrated, in shaping the LM curve, as well as the role of wage competitiveness constraints as a foundation of Keynes's relative wage hypothesis.     

Monetary regimes and the co-ordination of wage setting

A recent literature argues that a strict monetary regime may reduce equilibrium unemployment by disciplining wage setters, as wage setters abstain from raising wages to avoid a monetary contraction. However, in this literature the wage setters are assumed not to co-ordinate their wage setting. The present paper argues that precisely because a strict monetary regime may discipline the unco-ordinated wage setting, thus lowering unemployment in the unco-ordinated outcome, it also reduces wage setters’ incentives to co-ordinate. It is shown that an accommodating monetary regime may reduce equilibrium unemployment, via the strengthening of the wage setters’ incentives to co-ordinate.     

Pigou,Del Vecchio,and Sraffa: the 1955 International “Antonio Feltrinelli” Prize for the Economic and Social Sciences

In 1955, the Accademia Nazionale dei Lincei awarded the inaugural International “Feltrinelli” Prize for the Economic and Social Sciences to Arthur Cecil Pigou. This paper considers Gustavo Del Vecchio's active role on the selection committee in recommending Pigou for the Feltrinelli Prize and the related correspondence between Pigou, Piero Sraffa, and Del Vecchio. One of the most significant discovery reported in this paper is Sraffa's contention, expressed in an unpublished letter to Del Vecchio, that Pigou had “never been honoured in proportion to his merits.”     

Discrimination and the unemployment durations of white and black males

In this study we develop a model to decompose the longer unemployment duration of blacks into discriminatory and non-discriminatory components. By extending Becker's theory of discrimination to job-search theory, the discriminatory component is seen to be the result of two separate effects. First, a white treatment advantage shortens the unemployment duration of whites because they receive more frequent and higher wage offers than would prevail in the absence of discrimination for working alongside blacks. Second, a black treatment disadvantage lengthens the jobless spell of blacks because blacks receive lower wage offers than would prevail without discrimination as discriminating employers extract quasi-rents from their labour. We estimate our model using date from the CPS Displaced Workers Survey. The results show that 3.81 of the 4.58 weeks longer unemployment spell for blacks is due to discrimination, with 3.11 weeks resulting from the white treatment advantage, and 0.7 weeks emanating from the black treatment disadvantage.     

Robust central banking under wage bargaining: Is monetary policy transparency beneficial?

We study the role of transparency in an environment of robust monetary policy under wage bargaining. The standard view from the game-theoretical literature is that, with unionised labour markets, monetary policy transparency is unambiguously “bad” (it induces increases in wage and price inflation, unemployment and may lead to higher inflation uncertainty). The empirical literature is instead ambiguous about the macroeconomic effects of transparency. By recasting the earlier theory into a robust monetary policy environment, and focusing transparency on the uncertainty about the preference for price stability, we show that the macroeconomic effects of transparency are more favourable than normally found. The impact on nominal wages, inflation and real variables (real wages and unemployment) is not parameter-free but depends on the public's informedness about this coefficient. The impact on real variables is found to disappear in case unions do not internalise the effect of wage decisions on the economy (i.e. in the case of atomistic unions). Finally, we find that the effect of transparency on inflation uncertainty is more complex than in the standard approach. We show that transparency may have the beneficial effect of reducing inflation variability not only when monetary uncertainty is low (as previously reported), but also when monetary uncertainty exceeds an upper threshold.     

Patinkin as a reader of Keynes’ General Theory: Are wage cuts a good remedy to unemployment?1

Abstract

This paper analyses Patinkin's appraisal of Keynes’ concept of involuntary unemployment while focusing on his reading of the General Theory Chapter 19. On several critical issues, Patinkin departs from Keynes’ original matters of concerns. He leans against an individual criterion for unemployment and implicitly endorses Wicksell's understanding of voluntary unemployment as chosen leisure. His appraisal of involuntary unemployment as a disequilibrium phenomenon ultimately relies on nominal rigidities and assumes the existence of a competitive adjustment process. On all these three critical points, Patinkin departs from Keynes but also initiates the contemporary New Keynesian programme that went even further from Keynes.     

Wage Determination In Australia*

This paper examines whether a stable expectations-augmented Phillips curve exists for Australia. High real wages in the face of continuing high unemployment over the past decade have led to suggestions that the level of unemployment has little effect on wage determination, with the bargaining process taking place between employers and those employees in ‘secure employment’. Results from aggregate data suggest that the level of unemployment is relevant to wage determination. In addition, the impact of overtime on the growth in money wages is consistent with the view that those in secure employment are influenced by labour market conditions.     

Has the EMU reduced wage growth and unemployment? Testing a model of trade union behavior

Grüner (2010) argues that the introduction of the European Monetary Union (EMU) led to lower wage growth and lower unemployment in participating countries. According to Grüner, monetary centralization increases the amplitude of national business cycles, which leads to higher unemployment risk. In order to counter-balance this effect, trade unions lower their claims for wage mark-ups, resulting in lower wage growth and lower unemployment. This paper uses macroeconomic data on OECD countries and a difference-in-differences approach to empirically test the implications of this model. Although we come up with some weak evidence for increased business cycle amplitudes within the EMU, we neither find a significant general effect of the EMU on wage growth nor on unemployment.     

Tax Incidence in a Model with Efficiency Wages and Unemployment

Abstract

The purpose of the present paper is to examine the effects of taxation on income distribution in a model with efficiency wages and involuntary unemployment. Central to our efficiency-wage model is the hypothesis that firms set wages above market-clearing levels, whenever the productivity of labor depends on the real wage paid by the firm, and unemployment. Within a two sector general equilibrium model we study the incidence of factor and commodity taxes on income distribution, and unemployment. Our findings differ substantially from those derived by the traditional neoclassical analysis, originally developed by Harberger, and as it has been extended by several authors.     

The wage–employment relationship in Modigliani's 1944 article

Modigliani's 1944 “Econometrica” article is considered one of the most important efforts to reconcile Keynes with classical economic thinking through the wage rigidity hypothesis. The paper reconstructs the genesis of Modigliani's article and compares Modigliani's and Patinkin's interpretation of the wage–employment relationship. It also discusses Modigliani's contribution to the neoclassical synthesis, arguing that Modigliani's attention to the monetary origin of and solution to unemployment contrasts with the neoclassical synthesis neglecting of the monetary side of the system and its inclination towards fiscal policy.     

The U.S. inflation process: Does nominal wage inflation cause price inflation,vice-versa,or neither?

Low unemployment has revived concerns about accelerated inflation. This paper examines the relationship between price and nominal wage inflation. It finds that it varies by business cycle. Prior to the great oil shock of 1973, price and nominal wage inflation were unconnected in a Granger-causal sense. In the 1970s, wage inflation caused price inflation. In the 1980s, the relationship reversed and price inflation caused nominal wage inflation. In the 1990s, the pattern has changed again, and there is some weak evidence of bidirectional causality between wages and PPI inflation. However, wages continue to have no impact on CPI inflation, which is widely viewed as one of the Fed's target variables. This suggests that wage inflation should be de-emphasized as a monetary policy information variable.     

The Fault Line between Keynes and the Cambridge Keynesians: A Review Essay

This essay reviews Michael Ambrosi's important but neglected book on the formative period of Keynesian economics. The book traces the evolution of a Cambridge macroeconomic tradition running from Marshall and Pigou to Keynes, and interprets The General Theory as a response to Pigou's analysis of unemployment. Ambrosi also argues that Keynes's disciples, Richard Kahn, Nicholas Kaldor and Joan Robinson, were, in the 1930s, wedded to a Pigovian methodology and did not immediately recognise that Keynes had redefined the meaning of equilibrium in The General Theory. Keynes's attempt to redefine the analytical basis of neoclassical economics was thwarted, not merely by the neoclassical synthesis, but by those who claimed to be the inheritors and guardians of his vision.     

Wages,participation and unemployment in the economic transition of urban China1

Wages, participation and unemployment are major topics for researchers of the labour market. How have these measures evolved in the economic transition of urban China? Have they evolved in accordance with those in the Statistical Yearbook of China (produced by the National Bureau of Statistics, China) and previous studies? We find that the estimated wage level based on Urban Household Survey (UHS) data was higher than that in the Statistical Yearbook in earlier years, but the relationship has reversed since 1999. Our estimated participation rate is lower than that of Giles et al. (2006) but higher than Dong et al. (2007) and Maurer‐Fazio et al. (2007) . The analysis shows that the unemployment rate is lower than that estimated with the China Urban Labor Survey data in Giles et al. (2005) . Our estimation results on unemployment rates turn out to be more similar to those in Dong et al. (2007) but are different from those in Hu and Sheng (2007) . This analysis provides the first systematic comparison of the wage level from different sources, and supplements the existing estimates on participation and unemployment using a more representative dataset for urban China.     

Wage Flexibility and Unemployment: The Keynesian Perspective Revisited

Keynes' main concern in the General Theory is about the capacity of an economy to return to full employment equilibrium when subject to a (negative) demand shock. He maintains that money wages cuts may not help reabsorb unemployment, as they do not necessarily imply a fall in real wages. On the contrary, wage rigidity may be necessary for avoiding that a cumulative process propels the economy far away the full employment equilibrium. Co‐ordination failures in the investment‐saving market are behind this conclusion. However, the analysis is carried out within a static equilibrium framework. This paper is an attempt to focus on the problems of intertemporal co‐ordination arising within the context of a sequential economy. Our analysis of the out‐of‐equilibrium process of adjustment stirred by a shock allows to generalize the original Keynesian intuition. Unemployment emerges as the result of a lack of co‐ordination due to irreversibly constrained choices, and not only nominal but also real wage flexibility does not necessarily help to restore equilibrium. As a matter of fact, it may even be harmful, by triggering processes that make the economy diverge from equilibrium. Our analysis has important analytical implications as regards the role of market imperfections and the interpretation of the effects of monetary policy.     

The impact of minimum wages and foreign domestic workers in Taiwan

The purpose of setting the minimum wage is mainly to protect the rights and interests of vulnerable workers and to enhance productivity of labour. In this paper, an attempt has been made to explore the effect of the upwards adjustment of the minimum wage in Taiwan on the inflation rate, the unemployment rate, labour productivity, economic growth and other macroeconomic variables by means of an analysis of empirical data using a structural vector auto‐regressive model. The findings of the paper show that upwards adjustment of the minimum wage in Taiwan will not intensify the unemployment rate. On the contrary, it will help to promote labour productivity to an extent that will have a positive effect on the economic growth rate. In addition, this paper investigates, long‐term care system should incorporate the foreign domestic worker labour pool, which could provide the additional personnel necessary for the nation's long‐term care. Minimum wage should apply to foreign domestic workers, and foreign domestic workers should not be treated as a separate group of workers in minimum wage policy.     

Real Minimum Wage and Growth Theory: Simulations and Some Policy Results

Abstract

A Solow type two‐sector growth model is used to examine several issues related to growth and unemployment in a minimum wage economy. By simulating the model, we demonstrate that given the same percentage increase in wage rate, an economy with a higher capital–labor ratio is more likely to decay. More importantly, a tariff policy reduces the unemployment periods by 92% provided that the current capital–labor ratio is one‐sixth of that of the steady state capital–labor ratio. We assume that the first best policy of uniform wage subsidy is not politically feasible.
