‘To help keep the home going’: female labour supply in interwar London

Most prior work on historical female labour supply has been confined to looking at the female labour force participation decision. This article uses the detailed information on weekly hours of work and wages contained in the New Survey of London Life and Labour (NSLLL) (1928–32) to provide the first estimation of both the participation and the hours‐of‐work decisions for female workers prior to the Second World War. The main finding is that the labour supply curve was negatively sloped—women worked longer hours at lower wages. It is also possible to compare the determinants of the labour force participation decision and the hours of work decision among females in the NSLLL. It appears that the labour force participation decision was more strongly related to household income level than to own wages, while the hours of work decision among working women was more strongly related to the wage level than to household income. Finally, the article also examines the differential labour market behaviour of married women, female household heads, and young single women; most striking among these results is the evident added‐worker effect on married women of the onset of the Great Depression in 1930.     

Evidence on the Volunteer Labor Supply of Married Women

I estimate a significant, positive wage elasticity of married women's volunteer labor supply from 1975 to 1976 U.S. time diary data. Increases in the number of children in the household significantly raise participation rates but reduce volunteer hours. I find weak support for a sequential time allocation model of volunteering where the wage as the opportunity cost of time has only a second-order effect on volunteer hours. Increased hours of market work for married women decrease their volunteering. Cash and time donations are complements at the volunteer participation level but substitutes in terms of married women's volunteer hours.     

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.     

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.     

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.     

The Rising Supply of College Graduates and Declining Returns for Young Cohort: The Case of Korea

Abstract

This study analysed the effect of an increase in the supply of youth college graduates, in terms of the return on education. The rate of return on education in Korea substantially dropped from 1983 to 1994. Since then, however, the declining trend of the rate of return on education stopped and turned upward. The rate of return has declined especially for college graduates, and such a decline has been most prominent for young cohorts, among college graduates, since 1987. The observed trend of the rate of return appears to be related to the sharp increase of labour supply of college graduates since the mid 1980s.

The elasticity of substitution between education levels and age groups was estimated in this study, using a generalized demand-supply model. The effects of relative supply of college graduates (as a whole and by age) on the relative wages of college graduates by age were analysed under the assumption of constant skill-biased technological change. As it turned out, the relative college graduates’ labour supply of each age group had large bearings upon relative wages of each corresponding group, while the relative labour supply of all college graduates did not. It implies that labour is an imperfect substitute, not only between education levels but also between age groups.

Thus, as youth college graduates’ supply increases, there needs to be a corresponding demand increase for them, to avoid the drop in the wage or employment level for them. Therefore, to tackle with the issues of youth labour market, such as youth unemployment, separate policies targeting the youth group are called for.     

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.     

The productivity–wage relationship in South Africa: an empirical investigation

This article investigates the relationship between labour productivity, average real wages and the unemployment rate in South Africa at the macroeconomic level, using time‐series econometric techniques. There is strong evidence of a structural break in 1990, after which time all three variables rose rapidly. The break appears to have negatively affected the level of employment in the first instance, and subsequently fed through into per worker wages and productivity. A long‐term equilibrium (cointegrating) relationship was found between real wages and productivity, but unemployment was apparently unconnected to the system, which lends support to the insider–outsider theory. A long‐term wage–productivity elasticity of 0,58 indicates that productivity has grown more rapidly than wages, which is consistent with the finding that labour's share of gross output has been shrinking over the past decade. These trends may be explained plausibly by the adoption of job‐shedding technology and capital intensification.     

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.     

Why the industrial revolution was British: commerce,induced invention,and the scientific revolution1

Britain had a unique wage and price structure in the eighteenth century, and that structure is a key to explaining the inventions of the industrial revolution. British wages were very high by international standards, and energy was very cheap. This configuration led British firms to invent technologies that substituted capital and energy for labour. High wages also increased the supply of technology by enabling British people to acquire education and training. Britain's wage and price structure was the result of the country's success in international trade, and that owed much to mercantilism and imperialism. When technology was first invented, it was only profitable to use it in Britain, but eventually it was improved enough that it became cost‐effective abroad. When the ‘tipping point’ occurred, foreign countries adopted the technology in its most advanced form.     

Market wage or discrimination? The remuneration of male and female wool spinners in the seventeenth‐century Dutch Republic1

In the historical debate, the gender wage gap is usually attributed either to productivity differences or to gender discrimination. By analysing a newly constructed series of spinning wages in the seventeenth‐century Dutch Republic, the wages of male and female textile workers for the same work could be investigated. At first sight, the evidence on equal piece rates for spinning men and women seems to rule out wage discrimination. Nevertheless, more deeply rooted gender discrimination resulting from the segmented seventeenth‐century labour market restricted women's access to many professions. Exactly this segmentation determined differences in wage earning capacities between men and women.

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.     

Trade Union and Global Economic Growth

Abstract

This paper develops a simple framework for examining the role of unions in a global economy. It builds on the model of different institutions by comparing America with a flexible wage and Europe with a rigid wage (the existence of union), where the two areas are integrated via perfect capital mobility. We find the necessary condition that the degree of wage orientation of the union is larger than the firm's bargaining power and determines the positive direction on global economic growth. In addition, the effect of union's bargaining power on global economic growth is ambiguous. If the sum of the elasticity of substitution between capital and labour and the output elasticity of labour is smaller than one, or the firms are characterized by a Leontief production function (Harrod–Domar growth model) or an extremely low substituting elasticity (much empirical literature is supported), the union's bargaining power will lead to an increase in the growth of the global economy. In the general Cobb–Douglas production function (Solow–Swan neoclassical growth model), the union's bargaining power will result in a decline in the growth of the global economy.     

数字经济背景下互联网的使用对民营企业员工性别工资差距的影响——基于员工受教育层次差异化特征的分析

基于2017年中国综合社会调查的民营企业员工数据,使用稳健最小二乘回归与Oaxaca分解法研究发现:互联网的使用将对未接受过教育以及仅接受过私塾扫盲班/小学教育的民营企业员工工资产生显著的负向影响;互联网的使用将对接受过初中及以上教育的民营企业员工工资产生显著的正向影响;随着民营企业员工受教育水平的提升,互联网的使用对民营企业女性员工工资的弹性影响远超男性;互联网的使用将扩大未接受过教育的民营企业女性员工与男性员工的工资差距;互联网的使用将缩小接受过私塾扫盲班/小学及以上教育的民营企业女性员工与男性员工的工资差距.据此提出,应加大公益互联网使用培训力度,以提升女性的互联网理性使用水平、加强清扫虚假网络平台以防止受教育层次较低女性误入歧途、鼓励女性自主接受多元化再教育以提升自身互联网理性使用水平等,以缩小民营企业员工性别工资差距.     

Economic geography and inequality in China: Did improved market access widen spatial wage differences?

New economic geography (NEG) models predict that costly transport and the spatial distribution of demand affect the profits firms can earn in different locations, leading to higher wages for workers employed in cities with better geographic access to markets. In light of the ongoing economic integration and market reforms that occurred in China after 1995, we use three waves of Chinese Household Income Project (CHIP) data to measure the extent to which the influence of market access on wages changed and affected wage dispersion across Chinese cities over the next 12 years. Employing the gravity-based method of Redding and Venables (2004) to calculate the market access available to firms located in each city, we test whether the elasticity of the wage with respect to local market access increased over time. We find that in all three years market access of the worker's location has a positive and significant influence on the wage. Consistent with extensive labor market reforms of the late 1990s, the estimated wage elasticity doubles between 1995 and 2002 and is stable thereafter. Our estimates indicate that wages of all workers become more responsive to market forces in a manner consistent with NEG predictions, both skilled and unskilled and those working for state as well as private enterprises. We also provide evidence that these results are not driven by omission of other forms of agglomeration or by selection bias. Estimated spatial differences in nominal wages are large: a worker moving from an inland location to the coast in 2007 would have doubled his or her nominal wage. Counterfactual analysis indicates that spatial differences in market access contribute to wage inequality, but less so over time.     

Union relevance in the Malaysian labour market

The study estimates the effect of union membership on workers' wages using individual‐level data from a survey conducted among employees in various sectors in Malaysia in 2012. Initial results show that union membership has a positive effect on wages. However, after controlling for endogeneity, union membership or the presence of a labour union within a firm is not statistically significant for individual wage levels. Because there is no trade union wage premium, the study suggests that the revival of labour union membership is not going to be an easy task.     

Economic returns to schooling for China's Korean minority

This paper examines economic returns to schooling for China's Korean minority in the urban labour market using ordinary least squares (OLS) and two-stage least squares. The OLS estimates of the returns to schooling are similar to findings from recent studies for the Chinese urban labour market. We use parents’ education and spouse's education to instrument for education as well as exploit heteroskedasticity to aid in identification. The two-stage least squares estimates using parents’ and spouse's education are considerably higher than the OLS estimates for returns to schooling, while the estimates which exploit heteroskedasticity for identification lie between the OLS and conventional two-stage least squares estimates. The economic returns to schooling reported in this study assist in explaining why private demand for education is strong among the ethnic Koreans in China. It also provides a justification for the Korean minority's focus on educational attainment.     

Why married women's labor supply in the Netherlands has increased

Summary On the basis of cross-section data sets for 1979 and 1987 we determine: 1) the relative contribution of changes in participation and in hours of work to the increase in married women's labor supply; 2) how much of the change in participation and hours of work is determined by changes in preferences and in budget constraints; and 3) the causes of changes in market wages and reservation wages. The increase in the average unconditional hours of work is much more due to the rise in the participation rate than to the increase in conditional hours of work. Preference changes have contributed positively to the increase in married women's labor force participation over the period 1979–1987, whereas changes in market opportunities have contributed negatively. The change in the market wage and the reservation wage can be attributed mainly to changes in the population structure of married women. Changes in the model structure contributed negatively to the change in the real market and the reservation wage. The positive effect of the change in the population structure dominates the negative effect of the model structure. Finally, participants in the labor market have a comparative wage advantage over non-participants. Non-participants are a self-selecting group with a relatively high reservation wage.We like to thank Joop Hartog, Jules Theeuwes, Isolde Woittiez and two anonymous referees for their comments on a previous draft of this paper.     

Women's Economic Status in Rural China: Household Contributions to Male–Female Disparities in the Wage–Labor Market

Rapid industrial growth in China coupled with economic reforms in the rural areas has created a growing demand for rural women's labor, though often at substantially lower wages than those earned by men employed in the same sector. An analysis of data collected in rural Guangdong province suggests that households may contribute to the observed male–female market wage differential through their influence in the formation of individuals' reservation wages. Under these circumstances, external employment opportunities, while no doubt serving to increase the household's overall level of income, may, on their own, be a less effective mechanism for raising the economic status of women. On the contrary, market wage signals may serve to reinforce, rather than to ameliorate, sex-based differences that arise within the household.
