NOMINAL WAGE INDEXATION,QUASI‐EQUILIBRIA AND REAL WAGE DYNAMICS

In contrast to the traditional static approach to indexation, this paper analyses the dynamic consequences for real wages of the mechanism that links nominal wages to inflation. Revisiting a contribution by Dehez and Fitoussi on macroeconomic fluctuations , I analyse a monetary overlapping generations small open economy in which full indexation is interpreted as the occurrence of a dynamic ‘quasi‐equilibrium’. In the suggested framework, the nominal wage is linked to the inflation rate by a specific indexation formula whose shape relies on unions' bargaining positions. Assuming a constant peg for the real interest rate and the superneutrality of money, I show that the economy has a unique long‐run quasi‐equilibrium allocation whose stability depends only on the behaviour of the monetary authority. Moreover, I show how the operating of a ‘wage‐aspiration effect’ might lead to the persistence of involuntary unemployment.     

THE MINIMUM WAGE, WAGE SUBSIDIES, AND POVERTY

In an attempt to augment the lowest wages, the United States and several other countries utilize legal minimum wages. However, the minimum wage has potentially adverse employment effects. The analysis here suggests that an alternative policy that combines a minimum wage and a wage subsidy is superior to either by itself. Such a combination can assist the low wage worker, avoid disemployment effects, and maximize market efficiency.     

FIXED‐WAGES,WAGE DIFFERENTIALS AND WORKER HETEROGENEITIES

We study incentive‐compatible labour contracts in the case where individual productivity, preference for leisure and time preference rate are unobservable by the principal in a two‐period model. We first reduce this three‐dimensional problem to a standard one‐dimensional screening problem. Features of second‐best labour contracts provide a rationale for both fixed‐wages and wage differentials.     

EARNINGS INEQUALITY, LABOUR SUPPLY AND SCHOOLING IN HUSBAND–WIFE FAMILIES

This paper describes the association between market work and earnings inequality across families over the life cycle and over calendar time with special attention to the different experiences of college‐educated and high‐school‐educated people. A concise and effective accounting framework is developed that allows for an assessment of the effect of the growing market employment of married women on family earnings inequality. Applying this framework to pseudo‐panel data from successive Current Population Surveys indicates that the increase in wives' employment has diminished the growth in family earnings inequality especially for well‐educated couples. Inferences about the level and change in earnings inequality depend on the degree of labor market attachment of the people studied especially in the case of wives.     

Occupational gender composition and wages in Canada, 1987–1988

In this paper, we provide a comprehensive picture, circa the late 1980s, of occupational gender segregation in Canada and its consequences for wages. Our analysis reveals sensitivity of the estimated penalty to 'female work' to both specification and estimation strategy. Our preferred estimates indicate that the wage penalties for women in female jobs in Canada are generally smaller than penalties in the United States. Of particular note, while there is some heterogeneity across worker groups, on average the link between female wages and gender composition is small and generally not statistically significant.

Taux de féminité des professions et salaires au Canada: 1987–88. Dans cet article, les auteurs dressent un portrait complet de la ségrégation professionnelle fondée sur le sexe au Canada à la fin des années 1980, et de ses répercussions sur le niveau des salaires. Leur analyse révèle que les évaluations de la 'pénalité salariale' dans les emplois féminins dépendent du choix des méthodes d'estimation et des spécifications des fonctions. Les évaluations les plus robustes indiquent que, pour les femmes au Canada, la pénalité reliée aux emplois féminins est généralement plus faible que celle qu'on trouve aux Etats-Unis. Bien qu'on trouve des résultats différents selon les groupes de travailleurs, en moyenne, le lien entre le taux de féminité des professions et le niveau de salaires des femmes est faible, et n'est généralement pas statistiquement significatif.     

EARNINGS INEQUALITY IN GREAT BRITAIN 1975–90: THE ROLE OF AGE

This paper is concerned with the growing earnings dispersion among British men. The study is based on unit record data drawn from the New Earnings Survey. It is found that increases in inequality within age groups account for most of the rise in earnings inequality overall. Occupation too is a significant explanation of growing inequality among workers, but the major part of increased inequality within age groups remains unexplained.

POST-REFORM PRODUCTIVITY PERFORMANCE AND SOURCES OF GROWTH IN CHINESE INDUSTRY: 1980–85

This paper examines the productivity growth and its sources in 39 Chinese industries in the post-reform period 1980–85. We use both the gross-output and value-added models to isolate the contributions of labor, capital, materials and technical efficiency to growth in industrial output. Using new data from the National Industrial Census of China (1988) for large and medium-size enterprises, we find that Chinese industries, in particular, those in the manufacturing experienced sharp increases in total factor productivity growth in the 1984–85 period as compared to the 1980–84 period. Moreover, collective and private enterprises show higher output and total factor productivity gains than do state enterprises. Our regression results show that total factor productivity gains are closely tied to increases in retained profits and the proportion of total employees that are technical workers. However, labor bonuses have a negative effect on total factor productivity growth.     

基于SPSS的中国网络团购市场发展趋势及其区域差异研究

通过收集中国网络团购市场调研报告相关数据,采用回归、聚类和主成分分析等方法,对中国网络团购市场的发展趋势及区域差异进行了深入研究。结果表明,目前我国网络团购市场总体发展前景良好,但也存在不少问题。团购网站增长率已趋于平缓,维持在30％左右。同时,团购市场在不同区域存在较大差异,整体表现为“沿海快、内陆慢”,由东南沿海的较发达地区牵引向西北内陆的次发达地区发展。区域差异主要与不同城市的经济实力、居民生活水平和城市交通力有关,除北京和上海市场已较为成熟外,广州等6个城市是未来发展最为可观的城市,而武汉等10个城市则是未来发展潜力最大的城市。     

PRODUCT MARKET AND THE SIZE–WAGE DIFFERENTIAL*

Using directed search to model the product market and the labor market, I show that large plants can pay higher wages to homogeneous workers and earn higher expected profit per worker than small plants, although plants are identical except size. A large plant charges a higher price for its product and compensates buyers with a higher service probability. To capture this size‐ related benefit, large plants try to become larger by recruiting at high wages. This size–wage differential survives labor market competition because a high wage is harder to get than a low wage. Moreover, the size–wage differential increases with the product demand when demand is initially low and falls when demand is already high.     

Australian Stock Market Volatility: 1875–1987*

This paper investigates the volatility of monthly Australian stock returns over the period 1875–1987. There has been extensive work on this question in the United States, but little with data outside that country. Our analysis centres upon whether the 'stylized facts' regarding returns in the US also hold true for Australia. We find that there are both similarities and differences. There is little evidence for asymmetry in Australian returns but strong persistence of shocks into volatility. What is particularly interesting in the Australian series is the large volatility of the last two decades, an experience not matched in the US data     

UNEMPLOYMENT,LABOR MARKET TRANSITIONS,AND RESIDUAL WAGE DISPERSION

It is commonplace in the debate on Germany's labor market problems to argue that low wage dispersion is a major reason for the high unemployment rate. This paper analyzes the relationship between unemployment and residual wage dispersion for individuals with comparable attributes. In the conventional neoclassical point of view, wages are determined by the marginal product of the workers. Accordingly, increases in union minimum wages result in a decline of residual wage dispersion and higher unemployment. A competing view regards wage dispersion as the outcome of search frictions and the associated monopsony power of the firms. Accordingly, an increase in search frictions causes both higher unemployment and higher wage dispersion. The empirical analysis attempts to discriminate between the two hypotheses for West Germany analyzing the relationship between wage dispersion and both the level of unemployment as well as the transition rates between different labor market states. The findings are not completely consistent with either theory. However, as predicted by search theory, one robust result is that unemployment by cells is not negatively correlated with the within‐cell wage dispersion.
