What has Happened to Wages in the New Order?

This paper reviews trends in real wages in Indonesia since the early 1970s. It finds that there has been wage growth in a range of agricultural and non-agricultural sectors. However, growth has been uneven across sectors and for different periods. After the oil boom, wage growth slowed during the second half of the 1980s, although it picked up again in the 1990s. The paper discusses the relationship between various episodes of economic growth and labour market developments which might have contributed to patterns of wage change in various sectors. It also examines the influence of price deflators on real wage change, and compares trends in real earnings with trends in wage rates.     

An Equilibrium Theory of Wage and Employment Cyclicality by Gender and by Industry

This paper presents an equilibrium theory that accounts for how cyclical patterns of employment and real wages vary between genders and across industries. Workers' self-selection of industrial sectors, gender differences in comparative advantage among sectors, sector-nonneutral shocks, and resulting mobility of workers across sectors play the key roles in explaining wage and employment cyclicality by gender and by industry. Numerical simulations demonstrate that reasonable parameter values exist under which the current model accords with several stylized facts. These parameter values are characterized most importantly by men's comparative advantage in the sector subject to larger cyclical demand shocks.     

Labour Market Flexibility,Wages and Incomes in Sub‐Saharan Africa in the 1990s

Abstract: This paper provides an overview of how African labour markets have performed in the 1990s. It is argued that the failure of African labour markets to create good paying jobs has resulted in excess labour supply in the form of either open unemployment or a growing self‐employment sector. One explanation for this outcome is a lack of labour market ‘flexibility’ keeping formal sector wages above their equilibrium level and restricting job creation. We identify three attributes of labour market flexibility. First, whether real wages decline over time; secondly, the tendency for wages to adjust in the face of unemployment; and thirdly, the extent of wage differentials between sectors and/or firms of various size. Recent research shows that real wages in Africa during the 1990s may have been more downwardly flexible than previously thought and have been surprisingly responsive to unemployment rates, yet large wage differentials between formal and informal sector firms remain. This third sense of the term ‘inflexibility’ can explain a common factor across diverse African economies — the high income divide between those working in large firms and those not. Those working in the thriving self‐employment sector in Ghana have something in common with the unemployed in South Africa — both have very low income opportunities relative to those in large firms.     

Institutional wage-setting,labour demand and labour supply: Causal estimates from a South African pseudo-panel

Unemployment in South Africa has multiple causes. This article uses a district pseudo-panel to estimate the elasticity of labour demand, labour supply and unemployment with respect to wages. We assess whether hiring decisions are more sensitive to increases in wages of low-paid workers than high-paid workers, and whether wage growth prompts entry into the labour market. These channels combine to result in the positive causal effect of wage growth on unemployment. The research investigates whether these effects are dominated by districts in which unionisation rates are high and employment is concentrated in large firms. Wage growth of middle-paid to highly paid workers – as opposed to low-paid workers – reduces local labour demand and raises local unemployment. Bargaining arrangements correspond closely to the spatial wage distribution; in turn, a large part of the impact that wage growth has on labour market outcomes is determined by these wage-setting institutions.

ABSTRACT

Economic theory predicts that regional wages will converge as transport and communication technologies bring labour markets together. An exploration of this transition from labour market segmentation to unification requires long-term evidence of nominal wages and cost of living by region. This paper presents new evidence of wages for male manufacturing workers and cost-of-living indices across 24 Swedish counties between 1860 and 2009. Our findings indicate that the Swedish regional wage differentials were a great deal larger in the 1860s than in the 2000s. Most of the compression took place between the 1860s and World War I, as well as in the 1930s and during World War II. Differences in expenditures on housing impact on our assessment of convergence in the post-World War II decades: the nominal measure declines, while the real one stays constant. Our concluding discussion engages with the assumption that before World War I, regional wage convergence was associated with labour mobility, spurred by improved communication and transportation technologies as well as by the implementation of modern employment contracts. In the 1930s and 1940s, in contrast, regional wage convergence can be traced to high unionisation and centralised collective bargaining in the labour market, two distinguishing features of the Swedish Model.     

Variation in the Effects of Aggregate Demand Shocks: Evidence and Implications across Industrial Countries

Over a sample of nineteen industrial countries, more variable aggregate demand and/or higher mean inflation attenuates (augments) the effect of aggregate demand shocks on real output growth (wage and price inflation) while having no effect on the response of the real wage to such shocks. In all countries examined, aggregate demand shocks are positively (negatively) correlated with nominal variables (real output). Among explanations of the business cycle based on shocks to aggregate demand, this evidence favors the new Keynesian sticky wage explanation over the sticky price and the new classical imperfect information explanations.     

An empirical analysis of the unit labor cost-product price relation in the U.S. economy

This article tests for cointegration between unit labor costs and the level of product prices in four sectors of the U.S. economy: the aggregate business sector, the nonfinancial corporate sector, durable manufacturing, and nondurable manufacturing. A finding of cointegration for most specifications supports the existence of long-run labor market equilibrium for producers and suggests estimation of error-correction models to examine the dynamic relationships. In every sector except nondurable manufacturing, error-correction model estimates indicate there is a mutual feedback relationship between unit labor costs and prices. Controlling for deviations from full employment, oil price shocks, and the Nixon wage and price controls, the results also provide evidence of significant nominal wage indexation in U.S. labor markets. Throughout the economy there appears to exist both effective neoclassical wage and price adjustment mechanisms to maintain labor market equilibrium and short-run rigidities which may contribute to deviations from full employment outcomes.     

Wage Divergence and Asymmetries in Unemployment in a Model with Biased Technical Change

In an attempt to explain the different wage and unemployment responses in mainland Europe and the US to a fall in demand for low-skilled labour, we present a model with two levels of skills and two classes of goods. We analyse the response to skill-biased technical change in two distinct labour market regimes. A trade-off between wage divergence and unemployment of skilled and unskilled workers occurs. Skill-biased technical change turns out to have a different impact in both regimes, due to a different working of the chimney effect.     

Wage formation in the context of collective bargaining

Summary The article analyzes wage developments resulting from collective bargaining between one union representing all employees and one employers' organization representing all employers. The context is an economy consisting of two markets: a labour market and a goods market. An analysis has been made of the costs and benefits for both parties in case of a strike. The strength of both parties has been analyzed, firstly under the assumption of perfect information and thereafter under the assumption of imperfect information. Important determinants of wage increases appear to be the strike costs, the horizon, the bargaining skills and the self confidence of both parties and the wage elasticity of the demand for labour.I acknowledge the helpful comments of Professors Muysken, Kuipers and Pen.     

Oil demand in the US and Japan: why the demand reductions caused by the price increases of the 1970's won't be reversed by the price declines of the 1980's

This paper analyzes the imperfect price-reversibility (‘hysteresis’) of oil demand in the US and Japan. We test econometrically oil demand data, disaggregated into transportation oil and non-transportation oil uses.The oil demand reductions following the oil price increases of the 1970's will not be completely reversed by the price cuts of the 1980's. The responce to price cuts in the 1980's is perhaps only one-fifth that for price increases in the 1970's. This has dramatic implications for projections of oil demand, especially under low-price assumptions.We also consider the demand effects of a price recovery in the 1990's, especially whether the effects would be as large as for the price increases of the 1970's or only as large as the smaller demand reversals of the 1980's. On this the results are inconclusive.     

De Vraag Naar Liquiditeiten in Nederland, 1952–1971

Summary This study examines the demand for money (broadly defined) in the Netherlands. The basic model assumes the long run demand for money to depend upon expected real income and prices, the rate of interest and a cyclical indicator. The actual money balances approach equilibrium with an exponentially distributed lag. The model is estimated with seasonally adjusted quarterly data covering the period 1952: I-1971:IV. We found an income elasticity of 0.85 and an interest elasticity of –0.20, a price elasticity close to 1 and a negative correlation between the demand for money and the cyclical indicator. We also found some statistical evidence for the hypothesis that the demand function is stable over time.

Capital mobility and labor market volatility

We used a dynamic two-country optimizing model featuring efficiency wages to analyze the implications of capital mobility for labor market volatility. Capital mobility magnifies the short-run effects of productivity shocks and monetary shocks on employment and the real wage, but dampens the medium-run effects. The overall effects of capital mobility on the volatility and the cyclical properties of employment and the real wage are moderate.     

Inflation and the wage lag during the American Civil War

This paper examines the role of inflation in financing the American Civil War, and the effects of that inflation on the level of real wages in the North. A wage determination model is specified in which the equilibrium real wage is determined by real forces and the money wage is allowed to adjust to its equilibrium value with lags. Econometric estimates of the model support Wesley Clair Mitchell's contention that wage movements lagged price movements during the war. Comparison of the estimated equilibrium money wage and the estimated current money wage makes it possible to assess the magnitude and importance of the wartime redistribution of income attributable to inflation.     

The role of profits in econometric models

Summary The relative size of profits has dramatically fallen during the seventies. As profits are supposed to play a dominant and strategic role in western economies, the question rises whether model builders have been aware of this role and in which sectors of the economy profits are assumed to influence the behaviour of economic agents. In this contribution the econometric role of profits in three main fields of interest has been investigated, viz. wage and price formation, various demand equations and, finally, relations regarding the labour market. It appears that in empirically estimated econometric models, like the Brookings and Wharton E.F.U. Models for the United States and the Treasury Model for the United Kingdom, the role of profits is very limited. More important but still too restricted is this role in various Dutch models.     

Product market competition, unemployment and income disparities

Product Market Competition, Unemployment and Income Disparities. — We discuss how promoting competition in product markets affects unemployment and wage differentials. We examine a general equilibrium model with real wage rigidities in labor markets and market power in product markets. We illustrate how more intense competition reduces unemployment. A decrease of markups would induce an increase of real wages if real wages were flexible. This enables the employment of more low-skilled people above a real reservation wage. More intensive competition, however, widens wage and income differences between low-skilled and high-skilled workers. Differences of income distributions across countries could also be caused by differences in the intensity of product market competition.     

De produktiestructuur van Nederland in de periode 1950-1966

Summary In 1961 Arrow, Chenery, Minhas and Solow presented their C.E.S. production function, which was based on the relation between the real wage rate and the average labour productivity. They argued that, if the aggregate production function is continuous, lineair and homogeneous, then, with perfect competition and profit maximalization prevailing, the relation between the real wage rate and the average labour productivity is reflection of the production structure. This relation can, therefore, be used for specifying the production structure.In the present paper, the same line of thought is applied to the Dutch economy. Several hypotheses on the relation between wage rate and average labour productivity are tested. Statistically, it turns out that in the Dutch economy the elasticity of substitution between capital and labour is not a constant: it declines with increasing capital-labour ratio. Two statistically acceptable production equations that have this feature are presented.The efficiency parameter appearing as an integration constant in both production equations shows a decline: with labour productivity constant, the capital-labour ratio is falling over time. This means that the relation between labour productivity and capital-labour ratio shifts over time. Another outcome of this study is that technical progress is capitalaugmenting and that it brings about 50 percent of the growth in the labour productivity.De schrijvers zijn dank verschuldigd aan Prof. Dr. F.

ADAPTING TO NORTH-SOUTH TRADE:A GENERAL EQUILIBRIUM APPROACH TO POLICY OPTIONS

This paper develops a general equilibrium model of North-Southtrade with different wage setting regimes and a non-tradeablessector. Simulations confirm that substantial gains from tradeopenness can be accompanied by a significant deterioration inthe position of unskilled Northern workers. Increasing labourmarket flexibility will not correct this problem and protectionistmeasures, such as enforcing labour standards on the South, willreduce global income. Less conventional labour market policies,such as employment subsidies for unskilled workers, offer amore effective response, and one, moreover, which benefits workersin both the North and South.     

Revisiting wage subsidies: How pro-poor is a South African wage subsidy likely to be?

Wage subsidies have been used in both developed and developing countries to raise employment. After a decade of deliberation, the South African Government recently announced the introduction of a wage subsidy scheme. Given the intrinsic link between unemployment and poverty in South Africa, the belief is that a wage subsidy programme sufficient in scope will also make inroads into poverty. However, the way in which jobs are distributed among poor and non-poor jobseekers is crucial. Our general equilibrium microsimulation model confirms the expectation that a higher wage elasticity of labour demand is associated with larger reductions in poverty. We also find that a greater proportion of new jobs accrue to poor jobseekers when the elasticity is high. While youth-targeting does not improve the poverty-reducing effect of the policy, sectors such as textiles, accommodation, and construction services with their pro-poor employment profiles are good candidates for targeting.     

Wage misalignment in CFA countries: were labour market policies to blame?

Wage rigidity, stemming from highly distortive labour marketpolicies, is a natural candidate to explain the overvaluationof the CFA franc after the adverse external shocks of the 1980s.This paper uses a variety of data sources to assess wage rigidityin CFA countries until the 1994 devaluation, and to analysewhether it was due to labour market policies. The paper showsthat wages were high in CFA countries, compared with both wagesin similar countries and the labour earnings of similar individualswithin the same countries. It also shows that wages were rigidin real terms, in the sense of following closely the fluctuationsof government wages and consumer prices, but it finds no evidenceof nominal wage rigidity, though. From an international perspective,minimum wages were not high enough to account for the observedwage misalignment. Moreover, their adjustment over time washighly responsive to real shocks. Private sector unions, inturn, seemed more instrumental in achieving wage moderationthan wage drift. Their members usually had lower wages thansimilar, non-unionised workers, which probably reflects the'subordinate' nature of the labour movement. The most likelycandidates to explain wage misalignment and real rigidity inCFA countries in the 1980s and early 1990s are therefore governmentpay policies and (possibly) limited competition in product markets.
