Labour's share in twentieth-century Sweden: a reinterpretation

The distribution of national income between capital and labour is a classical theme in political economy. This paper takes a long-run perspective to the issue and asks two questions: How did the distribution of income between capital and labour develop in Sweden from 1900 to 2000? And how can this development best be explained? It is shown that labour's share in Sweden in the 100 years from 1900 to 2000 saw three important shifts, and the three shifts are analyzed. Around 1920, there was a surge in labour's share as workers mobilised in trade unions and universal suffrage and the eight-hour working day in manufacturing strengthened the bargaining power of workers. From 1950 until the late 1970s, there was another period of an increasing labour share, when the welfare state expanded and trade unions were strong. Contra the well-known postwar wage moderation analysis, there was no wage moderation in Sweden during the 1950s and 1960s, but rather the opposite: wages increased faster than productivity which caused a redistribution from capital to labour and reduced income inequality. The third shift occurred around 1980 when labour's share started a continuous decrease, beginning with several devaluations intended to increase profitability and competitiveness of Swedish business.     

Working hours in the European periphery: The length of the working day in Spain, 1885-1920

This paper studies the decline of the working day in Spain from 1885 to 1920. The decline was more continuous than previously thought. Differences in hours reinforce wage differentials, showing labor markets were not well integrated. Cross-sectional and time-series analysis suggests that hour reductions reflect a labor supply rather than a labor demand effect. Given the comparatively slow growth of real wages in Spain from 1870 to 1920, the Spanish case shows that international convergence in hours of work must have been stronger than convergence in wages.

A comparison of the wage structure between the public and private sectors in Japan

This study compares the wages in the public and private sectors in Japan. In addition to comparing overall wage levels, we examine the differences in the wage structures, specifically, the relative wages by gender, age, education, and region. The size of the public sector wage premium depends crucially on the size of the private companies chosen as the comparison group. Wage gaps by gender and educational attainment are smaller in the public sector than they are in private companies. The public sector's age–wage profile is steeper than that of the private sector. Public sector wages are more compressed. In other words, the wages are relatively higher at the lower end of the wage distribution and relatively lower at the higher end. The regional wage differentials are smaller in the public sector. Here, the wage levels of public sector workers are relatively higher in rural regions and relatively lower in large metropolitan regions. To ensure the efficient provision of public services, it is inappropriate to compare only mean wages.

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.     

The rise and fall of the sliding scale, or why wages are no longer indexed to product prices

Though almost no postwar union contracts indexed wage rates to prices of the employer’s products, union agreements linking wage rates to product prices, known as sliding scales, were common in some industries in the United States and Britain from the 1860s through the 1930s. This paper explains why sliding scales disappeared after the 1930s, and examines what practical experience with sliding scales revealed about fundamental constraints on wage indexation. Paradoxically, the history of sliding scales confirms that workers’ information about product prices and materials costs is generally imperfect, in ways that would substantially constrain wage indexation in long-term contracts. Sliding scales were not indexed long-term contracts, but rather devices to forestall costly strikes in the absence of contracts by revealing employers’ private information about product demand. In the postwar US, unions and employers failed to link wage rates to product prices because they had gained the ability to enter binding contracts, which could achieve the benefits of preventing strikes without incurring the extra negotiation costs and information problems associated with product-price indexation. I present a model to show how sliding scales could forestall strikes by revealing information, and how the introduction of binding union contracts reduced incentives to link wages to product prices.     

The Impact of Minimum Wages on Job Training: An Empirical Exploration with Establishment Data

Human capital theory suggests that workers may finance on-the-job training by accepting lower wages during the training period, Minimum wage laws could reduce job training, then, to the extent they prevent low-wage workers from offering sufficient wage cuts to finance training. Empirical findings on the relationship between minimum wages and job training have failed to reach a consensus. Previous research has relied primarily on survey data from individual workers that typically lack both detailed measures of job training and important information about the characteristics of firms. This study addresses the issue of minimum wages and on-the-job training with a unique employer survey. We find no evidence indicating that minimum wages reduce the average hours of training of trained employees and little to suggest that minimum wages reduce the percentage of workers receiving training.     

Wages,prices, and technology in early Catalan industrialization

Catalonia was the only Mediterranean region among the early followers of the British industrial revolution. The roots of this process can be traced back to the seventeenth and eighteenth centuries when the Catalan economy became integrated into international trade, and a successful printed calico industry concentrated in the city of Barcelona. Although the factory system was largely adopted by the cotton industry in the 1840s, the diffusion of the spinning jenny in Catalonia had occurred earlier, in the 1790s. In line with Allen, this article explores whether relative factor prices played a role in the widespread adoption of the spinning jenny in Catalonia. First, series of real wages in Barcelona are supplied for the period 1500–1808. Second, the prices of labour and capital are compared and the potential profitability of the adoption of the spinning jenny is analysed. Findings show that although Catalonia was not a high wage economy in the way that Britain was in the second half of the eighteenth century, evidence from the cotton spinning sector confirms the relevance of relative factor prices in the adoption of new technology. Within the booming cotton sector after the 1780s, high wages created strong incentives for the adoption of the labour‐saving spinning jenny.     

Regional wage convergence in Spain 1850–1930

This paper presents a new regional database on real wages for Spain from 1850 to 1930. This evidence is used to analyze the evolution of wages across regions and occupations. Substantial wage convergence occurred from 1850 to 1914, despite low rates of internal migration. World War I and the subsequent globalization backlash were associated with a spectacular increase in wage differentials. However, real wage convergence across Spanish provinces resumed during the 1920s, this time accompanied by high rates of internal migration.     

工资对个人劳动供给的非线性影响：部门市场化程度差异视角

从市场经济体制的建立到经济社会高质量发展，我国不同部门市场化程度有所差异，劳动供给的部门异质性随之体现。基于中国劳动力动态调查数据，结合汉森门槛回归模型和劳动供给模型，依托部门市场化程度的差异性，文章探讨了工资对劳动力个人供给的非线性影响及其部门异质性。主要得出以下研究结论：第一，我国市场部门与公共部门劳动力的个人劳动供给有所差异。第二，工资与个人劳动供给呈现非线性关系并且存在部门异质性。实证分析结果显示，工资对个人劳动供给的影响存在三个"突变点"，工资门槛均使得工资"激励效应"加强并呈现逐步增加的趋势。第三，劳动供给的工资门槛存在性别、城乡和行业异质性。第四，随着年龄增长、人力资本积累，个人劳动时间供给趋于降低，签署书面劳工合同使得市场部门劳动力工作时间显著增加，而政治面貌显著影响公共部门劳动供给。总体来看，无论是市场部门还是公共部门，我国劳动力个人供给曲线均未"向后弯曲"，国民经济高质量发展、改善收入分配格局、提升居民幸福感等议题需持续关注。     

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.     

Trends in real wages during the industrial revolution: a view from across the Irish Sea

This article calculates cost of living indices for Ireland between 1785 and 1870 and real wage indices for agricultural labourers, textile workers, and building workers. These indices show gains in real wages which are not consistent with current hypotheses about widespread pre-Famine immiseration, though textile workers did experience a reduction in earning power. Before the Famine, wages proved sticky downwards in the face of falling prices; after the Famine, money wages rose faster than prices. A revised UK index suggests that real wages began their increase earlier, in the 1820s, and increased by around an additional 10 percentage points by 1870.     

Black-white wage differential: The relative importance of human capital and labor market structure

This article uses the decomposition analysis developed by Neumark and the 1987 CPS data to investigate the relative importance of human capital and labor market structure in explaining the observed wage differential between white males and blacks (both male and female). We find that labor market structure, as opposed to differences in human capital, explains a relatively large portion of the wage gap between white males and blacks. In addition to blacks and whites being paid different wages for the same work, they are also given unequal opportunities. This means that narrowing the human capital gap between the races will not be enough to close the wage gap, as argued by human capital theorists. It is equally important to pursue policies that provide access to higher paying jobs and industries for blacks.     

The Industrial Tribunals and Wage Determination in the Australian Iron and Steel Industry, 1921–38

It is believed in some quarters that the system of federal and state industrial tribunals in Australia has exercised a considerable impact on the determination of wages in Australia, making the average level of nominal wages more inflexible and wage differentials more equal in the interwar period. The purpose of this paper is to identify, through cross-country comparisons, the impact that the industrial tribunals had on the iron and steel industry labour market, an industry that played a crucial role in Australia's industrial development during the 1920s and 1930s.     

Monopsony in the Labor Market,Minimum Wages and the Time Horizon: Some Unresolved Issues

This article discusses development of optimal solutions for monopsony in the labour market for the long run (when labour and capital are both flexible). It is shown that binding minimum wages up to a certain degree pushes the monopsonists to choose a high capital intensity of production, just as high as or even higher than that chosen when there is no regulation for minimum wages. Thereby, we demonstrate the existence of re-switching effects in the tradition of Piero Sraffa. The second part of the paper recalculates and analyzes earlier results by making use of the rather general constant elasticity of substitution production function. Based on a numerical solution for optimal monopsony under different regimes (no minimum wage, minimum wages of different values, etc.), we formulate a two-period game between the government and the monopsonistic firm (‘minimum wage game’). Finally, we analyze the relationship between the elasticity of substitution on the one hand and likely levels of employment on the other hand, after introduction of minimum wages.     

试论我国农民工工资权的法律保障

劳动者的工资权是劳动权的核心内容,也是劳动行为追求的终极目的。现阶段我国农民工工资仍然存在诸如工资水平普遍偏低、拖欠和随意克扣工资现象依然存在、加班加点工资严重缺失等方面的问题。基本人权的保障、社会的发展和弱势群体的关注需要国家对农民工工资权予以法律保障。要确实保障我国农民工工资权就必须制定《工资支付法》、建立欠薪保障制度、加强劳动保障监察机制、发挥工会组织维权机制、增设恶意欠薪刑事责任。     

Capital market distortion,firm entry and wage inequality

Distortions in the capital market are notable in developing economies like China. By building up a dual production structure with oligopolistic competition in urban manufacturing, this paper investigates the distributional and welfare effects of capital market distortions. We find that in the short run, an increase in the capital market distortion in favor of urban firms can lower both the skilled and unskilled wages. However, in the long run, the preferential policy on reducing capital cost to the urban sector attracts new entry of firms, which can worsen the skilled-unskilled wage inequality in the economy. This firm-entry effect of the capital market distortion on wage inequality is empirically confirmed for China.     

Employment and Earnings: A Case Study of Urban Detroit

This paper investigates the roles of manufacturing employment, neighborhood poverty, and family structure in determining wages among Detroit, MI workers, just prior to the current economic crisis. Employment in manufacturing has been crucial for blacks and whites: 39% of black and of white men in the Detroit metropolitan area worked in manufacturing in 2000. Regression analysis in this paper estimates employment in manufacturing raised wages 15.8% for all workers in the metropolitan area, 24.4% for blacks and 13.8% for whites. It finds a higher wage penalty (4.7%) for blacks in non-manufacturing industries than is found when manufacturing sector jobs are included (2.6%). Wage returns to education were greater in the non-manufacturing employment sector, especially for blacks. Residence in the poorest central city neighborhoods reduced wages significantly for white manufacturing and non-manufacturing workers. Its coefficient was insignificant for black workers. Gender and marital status effects on wages differed between blacks and whites in magnitude: White women suffered a larger penalty for their sex than black women (22.6 versus 9.6%) yet black men enjoyed a greater return to marriage than white men (27.5 versus 25.0%). Controlling for manufacturing reduced the gender wage gap and the returns to marriage for men. These findings suggest greater accessibility for women; and lower returns to marriage in non-manufacturing sectors. Among employed blacks access to manufacturing jobs has been their main source of decent wages. The adverse effects of the industry??s job loss in the 1980s and 1990s impacted all Detroit residents. Other high wage industries have employed relatively few blacks, have not paid them well; and have suffered job loss and slow growth over the period. Education could have raised wages for non-manufacturing workers, but not as much as access to manufacturing jobs. Today as in 2000, Detroit??s residents desperately need job creation or relocation to the central city; and job training and anti-discrimination policy enforcement throughout the metro-area. All of these would be necessary to offset job loss and reduce inequality and poverty in Detroit. The extent to which blacks will benefit from 2010?C11 improvements in manufacturing employment in Detroit depends upon whether private companies and the state provide equal access to the jobs and the training new technologies require.     

Product price differences across countries: determinants and effects

A substantial part of international differences in prices of individual products, both goods and services, can be explained by differences in per capita income, wage compression, or low wage dispersion among low-wage workers, and exchange rate fluctuations. Higher per capita income is associated with higher prices and higher wage dispersion with lower prices. The effects of higher income and wage dispersion are moderated for the more tradable products. The effects of wage dispersion, on the other hand, are magnified for the more labor-intensive products, particularly low-skill services. The differences in prices across countries are reflected in differences in the composition of consumption. Countries in which prices of labor-intensive services are very high, such as the Nordic countries, consume much less of them. For some services, the shares of GDP consumed in high-price countries are less than 20% of the shares in low-price countries. Since these are services of very low tradability, the low consumption levels of these services imply low employment in them.     

The new Ricardian specific factor model

This paper explores the implications on trade and wage inequality of introducing financial capital or credit in the standard Ricardian model of production, where a given amount of start-up credit is used to employ sector specific skilled and unskilled workers following the Wage Fund approach of classical economists. Thus, we have the Specific Factor (SF) structure of Jones (1971) in a new Ricardian model (NRM) with credit and two types of labour. With an entirely different mechanism from the conventional Neo-Classical structure, distributional consequences of changes in endowments, commodity prices, and financial capital are established. Comparisons with Jones (1971) show that unlike SF model, credit expansion affects wages and nominal costs without affecting trade patterns, while rise in the relative price of the skill-intensive good causes skilled wage to hike less than proportionately, and may cause return to capital to inflate more than the wages. We extend the basic model to analyse immigration, unemployment and imperfect credit market.
