A New Specification of Labour Supply in the MONASH Model with an Illustrative Application

MONASH is a dynamic general equilibrium model of the Australian economy. This article describes a new labour-market specification for MONASH in which people are allocated in year t to categories according to their labourmarket activities in year t – 1. People in each category plan their labour supplies by solving an optimisation problem. Via these problems, we introduce the assumption that people in employment categories supply labour more strongly to employment activities than do people in unemployment categories. Thus we find that employment-stimulating policies in t – 1 increase labour supply in t by shifting the composition of the labour force in t in favour of employment categories and away from unemployment categories. We illustrate this idea by using MONASH to simulate the Dawkins proposal to combine a freeze on award wage rates with tax credits for low-wage workers in low-income families. We find that the Dawkins policy would generate a significant short-run increase in employment. With the increase in employment generating an increase in labour supply, the employment benefits of the policy would persist over many years. However, in the long run, we would expect the effect of the policy on aggregate employment to be small and to depend on how the policy affected the ratio of real after-tax wage rates to unemployment benefits.     

PoJjcy and the Australian Economy, 1977

At the end of the first quarter of 1977 the available economic indicators, while as usual far from univocal, still give cause for serious concern about the health and direction of the Australian economy. With no significant expansionary factors operating in the economy in 1977 other than the revival in the mining industry and in some aspects of business investment, and the various arms of economic policy being set almost entirely in a restrictive stance, aggregate output would appear to be either flat or declining modestly at the present time. On the basis of a continuation of present policies we would anticipate growth in real non-farm GDP of only 2 to 3 per cent in both 1976–77 and 1977–78, with unemployment continuing to increase until well into 1978. Given the stimulus to inflation arising from the 1976 devaluation and from the wage effects of the Medibank changes, the rate of increase in the consumer price index would seem likely to be 14 to 15 per cent in 1977, even if a partial wage indexation policy could be sustained and whether or not a one quarter wage/price deferment comes into effect. But government pressure on the Arbitration Commission for a reduction in real wages has placed the wage indexation system in jeopardy, and there is now considerable uncertainty about the methods of wage fixation which will obtain in 1977–78. This article surveys some aspects of recent developments and considers some policy options available to the government.     

On the Provision of Insurance against Search‐Induced Wage Fluctuations*

Should workers be provided with insurance against search‐induced wage fluctuations? To answer this question, I rely on the numerical simulations of a model of on‐the‐job search and precautionary savings. The model is calibrated to low‐skilled workers in the United States. The extent of insurance is determined by the degree of progressivity of a non‐linear transfer schedule. The fundamental trade‐off is that a more generous provision of insurance reduces incentives to search for better‐paying jobs, which increases the cost of providing insurance. I show that progressivity raises the search intensity of unemployed workers, which reduces the equilibrium rate of unemployment, but it lowers the search intensity of employed job seekers, which reduces the output level. I also solve numerically for the optimal non‐linear transfer schedule. The optimal policy is to provide little insurance up to a monthly income level of $1350, so as to preserve incentives to move up the wage ladder, and nearly full insurance above $1450. This policy reduces the standard deviation of labor income net of transfers by 34 per cent and generates a consumption‐equivalent welfare gain of 0.7 per cent. The absence of private savings does not fundamentally change the shape of the optimal transfer function, but tilts the optimal policy towards more insurance, at the expense of a less efficient allocation of workers across jobs.     

Fiscal Transfers and Distributive Conflict in a Simple Endogenous Growth Model with Unemployment

Abstract. In the simplified formal treatment proposed in this paper, a decrease in a policy parameter – the ratio of total tax revenues to GDP – can monotonically increase long-term growth rate and may lead to a higher employment level. This notwithstanding, the paper shows that the redistributive implications of such a decrease may induce the wage earners to oppose it. As a consequence, policy-makers reflecting social preferences may undertake redistributive transfers generating persistent unemployment and lowering growth even if commitment technologies allowing them to follow preannounced tax policies were feasible.     

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 .     

The importance of the distinction between long- and short-term unemployment in UK macroeconometric models

This paper examines the degree of support for distinct duration effects on wages across a variety of wage equations, and investigates their importance in full simulations with three large-scale UK macroeconometric models. The paper begins by highlighting deficiencies both in the way that existing models determine the duration structure of unemployment and in the specification of long-term unemployment in the wage equation. By constructing a single preferred wage equation we test hypotheses relating to duration effects and, although tests are not conclusive, find some support for the use of short-term unemployment in the wage equation. However, it is also shown that the response of wages to changes in unemployment is similar regardless of whether aggregate or short-term unemployment is used in the wage equation, although this does not hold when the duration structure of unemployment changes radically. By substituting revised equations into the models we show that these results carry over to full model simulations. Thus although neglect of duration effects may not be crucial in assessing the effectiveness of standard macro policy instruments, this is not likely to be true when evaluating policies which are deliberately targeted at the long-term unemployed.     

Unemployment,inflation and price expectations with empirical results for Belgium

This article deals with the question whether there exists a trade-off between inflation and unemployment in the short as well as in the long run in the Belgian economy. A wage-price model incorporating the phenomenon of price expectations is presented. The model is verified empirically and an inquiry is made into the dynamic characteristics of Belgium's wage-price nexus. The main results of the paper are first that a positive answer may be given to the question we asked ourselves and secondly, that the possibility of explosive behaviour of wage and price changes is to be excluded.     

Labour market institutions and wage setting: evidence for OECD countries

The main channel through which labour market institutions are supposed to work in affecting unemployment is through their effects on the key parameters of the wage curve. In particular, labour market institutions may have both a direct wage push (or level) effect, i.e. change the level of the real wage for any given level of the unemployment rate and productivity, and an indirect slope effect, i.e. change the responsiveness of the real wage to the unemployment rate. The question this article addresses is whether there is any evidence that these transmission mechanisms were at work in a group of 20 Organization for Economic Co-operation and Development (OECD) countries over the period 1960 to 1999. The analysis is accomplished in two steps. Pooled Mean Group (PMG) estimates of a wage equation including unemployment, productivity and a set of wage push institutions are first obtained, allowing only a subset of institutional coefficient to be homogeneous, while leaving the unemployment and other coefficients free to differ across countries. The country specific estimates of the unemployment coefficients are then used to investigate whether and to what extent cross-country heterogeneity in the estimated wage response to unemployment is related to institutional differences. The results support the existence of significant wage push effects of union density and benefit replacement rates, and of significant slope effects of benefit replacement rates, benefit duration and employment protection. A more generous unemployment benefit structure is found to lower the wage responsiveness to unemployment, while higher employment protection, contrary to what one expects, is found to enhance it. No significant level and slope effects are found for the tax wedge and bargaining coordination.     

Small Firms and Unemployment in a Two-sector Model

This paper presents a two-sector model of an economy – one sector consisting of large firms with institutionally determined wage (the Formal sector) and the other sector consisting of small firms (the Informal sector). The paper examines the effects of changes in benefits, entrepreneurial zeal, and the institutionally determined wage in the Formal sector on unemployment. It concludes with brief comments on the role of aggregate demand and supply policies in reducing unemployment in this economy.     

Policy Influences on Unemployment: the European Experience

This paper considers the implications of four kinds of labour market policies for the 1980s rise in European unemployment: unemployment compensation, active labour market policies, employment protection legislation and taxation. It finds evidence that all have played a role in the determination of unemployment and discusses the mechanisms involved, the extent of the influence of each and the lessons learned from this experience. One of the main findings is that there is a trade‐off between wage inequality and unemployment. Policy has played a role in determining how a country responded to the negative macroeconomic shocks of the 1980s but policy alone cannot explain the full rise in European unemployment and North American wage inequality.     

Effect of labor market policies on unemployment when firms adapt their recruitment strategy

Firms conduct interviews to select who to hire. Their recruitment strategies affect not only the hiring rate but also job destruction rate as more interviews increase the chances of finding the right worker for the job; a link mostly overlooked in the literature. I model this recruitment behavior and investigate the effects of labor market policies on unemployment. These policies change the value of hiring the right worker, altering firms' incentives to conduct interviews. Policies further affect job creation and destruction when firms adapt their recruitment strategies. Net effect of a policy on unemployment depends on the magnitude of change in job creation versus destruction. Qualitative analysis reveals that the effect of a policy on unemployment is mostly weakened with the introduction of firms' recruitment behavior to the model. Firing taxes still increase unemployment, albeit at a lower rate. The effect of hiring subsidies on unemployment is even reversed: Unemployment increases with hiring subsidies if firms adapt. Minimum wage and unemployment insurance policies are also analyzed.     

The importance of composition of fiscal policy: evidence from different exchange rate regimes

We study the macroeconomic effects of fiscal policies in an open economy. We emphasize two transmission mechanisms: the cost channel, by which wage government spending and labor taxes raise the real wage firms must pay, and the exchange rate channel, by which the nominal exchange rate shifts induced by fiscal policy have real effects if (some) prices and wages are sticky. The latter channel implies that changes in wage government spending or in labor taxation should have different effects under flexible than under fixed exchange rates. In a 1964–93 panel of OECD countries we find significant evidence for both channels. Moreover, we find that the real product wage and profitability are more responsive than quantities (employment and output) to fiscal policy innovations.     

On the limits of rational expectations for policy analysis

In this lecture, I review work addressing three questions. First, are predictions about macro stabilization policies robust to reasonable departures from rational expectations? Second, do people's expectations converge to a particular set of rational expectations? Third, if they do converge, how quickly? I discuss examples from the literature where the answer to the first question is no. The answer to the second question is that learning equilibria converge to the “standard” rational equilibria analyzed in new Keynesian models. Finally, I discuss circumstances under which the answer to the third question is very slowly. In the examples, learning is slowest and policy analysis based on rational expectations is least robust in the face of shocks that render the stakes of getting policy “right” the highest.     

Industry-Level Wage Bargaining: A Partial Rehabilitation—The German Experience

In order to reduce unemployment, it is often recommended that industry-level wage bargaining in Germany should be replaced by a more decentralized system. This paper provides a critical assessment of the current wage bargaining institutions and re-examines the case for a more decentralized system. Based on a theoretical model integrating Insider–Outsider aspects into the comparison, the uniformly superior employment performance of a decentralized wage bargaining system is questioned. We conclude that, rather than solely trying to decentralize wage bargaining, a promising policy option may be to improve the skills of the unemployed by efficient labour market policies and to foster institutional reforms such that wage bargaining takes account of the long-run employment consequences of wage setting.     

Wage differentials and state‐private sector employment choice in Yugoslavia*

In this study we use the newly available Yugoslavian Labor Force Survey data to investigate wage differentials and employment decisions in the state and private sectors in Yugoslavia. For the analysis we use three empirical models that rely on different statistical assumptions. We extend the standard switching regression model to allow non‐normality in the joint distribution of the error terms. After correcting for the sector selection bias and controlling for workers’ characteristics we find a private sector wage advantage. The wage premium is largest for workers with low education levels and declining for workers with higher educational levels. Given the regulatory and tax policies that pushed the private sector into the informal sphere of the economy during the period covered by our data, we argue that the state/private wage gap is likely to grow in the future. This will make it increasingly difficult for the state sector to attract and retain highly skilled employees.     

Macroeconomic Policy and Employment Growth in Australia

Abstract
This article, which explores various aspects of macroeconomic policy and employment growth, is prompted by the relative lack of attention given to these issues in the Green and White Papers on unemployment. The problem of hysteresis reinforces the generally recognised need to reduce the excessive volatility of output and employment growth in Australia. International comparisons presented in the article suggest that Australian output and employment growth have been more volatile than those of the three major OECD countries. Reduction in macroeconomic volatility requires more effective short-term demand management than we have had in the recent past, and in turn, means that we must know more about the strength and timing of the effects of major macroeconomic policy instruments on employment growth and unemployment. This article presents employment growth equations for Australia over the period 1979–93 which incorporate domestic macroeconomic policy effects as well as the influences of the international business cycle. We show that monetary and fiscal policy have had a significant impact on the evolution of employment in Australia and, in particular, that tight monetary and fiscal policy contributed substantially to the recession of 1990–92.     

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.     

A welfare economic analysis of labor market policies in the Harris–Todaro model

This paper presents a welfare economic analysis of the benefits of various labor market policies in the Harris–Todaro labor market model. The policies considered are a policy of modern sector job creation, which I call modern sector enlargement (MSENL); a policy of rural development, which I call traditional sector enrichment (TSENR); and a policy of wage limitation in the urban economy, which I call modern sector wage restraint (MSWR). First, I analyze the inequality effects of these policies. I then perform two welfare economic analyses, the first based on summary measures of labor market conditions (total labor earnings, unemployment, inequality of labor incomes, and poverty rates) and the second based on dominance analysis in the labor market, in both cases assuming that the costs are borne elsewhere. The results of the welfare analyses are compared, and it is shown that TSENR unambiguously increases welfare in the labor market using both approaches, the other policies yield ambiguous results, and no policy is unambiguously welfare-decreasing.     

Redistribution and employment policies with endogenous unemployment

We study optimal redistribution policy in an economy with three types of unemployed persons: those unable to work, the voluntarily unemployed, and the involuntarily unemployed. Both voluntary and involuntary unemployment are endogenous. Voluntary unemployment arises because individuals have different preferences, while involuntary unemployment results from frictions in the labour market or from an efficiency wage. We consider the employment policies of a well-informed government when it can and cannot commit to its policies. The model is simple, yet rich enough to reflect real-world policies, including transfers to the disabled, welfare for non-working employables, unemployment insurance, employment subsidies, and taxes on workers and firms.     

Transitions across labor market states including formal/informal division in Egypt

This study examines the worker transitions across labor market states including formal/informal division using panel data of 2006 to 2012 from Egypt. We generate a broad set of facts about labor market dynamics in Egypt. We first develop transition probabilities by gender across different labor market states including formal/informal sectors utilizing Markov transition processes. Government employment is the most persistent labor market state for both men and women and the out of labor force is the second most persistent labor market state for women. Unemployment is the most mobile labor market state. Informal private wage work and self‐employed–agriculture are also relatively mobile labor market states. We next identify the effects of individual, household and job characteristics on different mobility patterns by estimating multinomial logit models. We find that gender, age, education, experience, and several sectors of economic activity are associated with the transition probabilities between the labor market states considered such as formal wage, informal wage, self‐employment, unemployment, government employment, and out of labor market. Education, in particular, university degree or above is noted to play a vital role in the probability of transitions across several labor market states.
