论劳动合同的试用期限制度

试用期限是劳动合同的一个重要组成部份,对于劳动合同的双方都具有重要的意义。我国应完善有关 法律,对试用期限作出系统明确的规定,以防止用人单位利用试用期限损害劳动者的合法权益。     

北京市农业转移劳动力工资差异及变化从工作经验到工作岗位

[目的]基于实证分析,探究农业转移劳动力工资的影响因素、工资差异的来源及其动态变化,以期为微观农业转移劳动力实现市民化提供科学参考。[方法]文章以2007—2017年北京市农业转移劳动力调研数据,通过多元回归、明瑟方程和基尼系数分解法、泰尔指数分解法,对农业转移劳动力工资的影响因素和工资差异进行分析。[结果](1)性别、教育程度、所属行业、工作岗位、工作经验是影响工资的主要因素;(2)工作岗位、所属行业、工作经验是工资差异的主要来源;(3) 2007—2017年10年来工资差异最重要的来源已从工作经验转变为工作岗位;且人力资本变量中工作经验对工资的影响高于教育年数,但教育的影响呈上升趋势。[结论]提出农业转移劳动力行动路径和政府政策建议:农业转移劳动力需努力提高自身素质、当前积极积累专业工作经验、有针对性参加培训、长期则需提高教育水平;政府应坚持市场化、工作设计多样化、规范收入分配、提供技能和学历教育平台。     

Impact of international trade on unemployment under oligopoly

By studying a two-sector general equilibrium model in which firms engage in oligopolistic competition and unemployment is a result of the existence of efficiency wages, we derive the following results analytically. A country's comparative advantage in producing manufactured goods increases with the level of efficiencies in the labor market. The opening of international trade leads to the equalization of wage rates even though countries differ in their factor endowments and labor market efficiencies. If countries have the same level of labor market efficiencies but differ in their endowments of labor and land, the opening to international trade leads to an increase in the wage rate in both countries.     

Wages,Prices and Agriculture: How Can Indian Agriculture Cope with Rising Wages?

Rapid economic growth in India has resulted in rapidly rising rural wages. Using the framework of variable profit functions and household level data, we study econometrically the wage impacts on crop agriculture. Rising wages are associated with decreasing crop output, other things being equal. Crop prices would need to increase by 80% in the short run to offset the effect of an agricultural wage increase, or by 140% in the short run to offset rural non‐farm wage increases as well. However, because non‐land farm assets respond positively to the non‐farm wage, in the medium term this increase is reduced to 74%. During the period of 1999/00‐2007/08, growth in non‐land farm assets, the labour force, education and technology has easily compensated for the wage increase, and probably also for the accelerating wage growth. Focusing on growing these shifter variables is a much better policy option than raising prices that would come at the expense of consumers or taxpayers.     

Exact Utilities under Alternative Monetary Rules in a Simple Macro Model with Optimizing Agents

We construct an optimizing-agent model of a closed economy which is simple enough that we can use it to make exact utility calculations. There is a stabilization problem because there are one-period nominal contracts for wages, or prices, or both and shocks that are unknown at the time when contracts are signed. We evaluate alternative monetary policy rules using the utility function of the representative agent. Fully optimal policy can attain the Pareto-optimal equilibrium. Fully optimal policy is contrasted with both naive and sophisticated simple rules that involve, respectively, complete stabilization and optimal stabilization of one variable or a combination two variables. With wage contracts, outcomes depend crucially on whether there are also price contracts. For example, if labor supply is relatively inelastic, for productivity shocks, nominal income stabilization yields higher welfare when there are no price contracts. However, with price contracts, outcomes are independent of whether there are wage contracts, except, of course, for the nominal wage.     

The Employment and Earnings Gaps between Natives and Immigrants in the UK between 1981 and 2006

We exploit the sizeable and long Lifetime Labour Market Database (LLMDB) to estimate the immigrant–native employment gap across gender, across continents of nationality and across lengths of stay in the UK between 1981 and 2006. These estimates are a novel contribution, as estimates for men and women are scarce in the literature and estimates across immigrants’ origins and lengths of stay are as yet unavailable. Furthermore, we estimate the employment gap as the differential in the number of employed weeks in the year between immigrants and natives, which has not been done before – this contrasts with the employment probability gap usually estimated in the literature. We also estimate the immigrant–native earnings gap across gender, across the entire earnings distribution, across continents of nationality and across lengths of stay. Estimates across the earnings distribution are also a novel contribution, as these are also as yet unavailable in the literature. Our main conclusion is that both the immigrant–native employment and earnings gaps vary across gender, continents of nationality and lengths of stay. Immigrant women earn more than native women throughout the distribution. The earnings gap is positive throughout for females: smaller at the bottom, larger at the top and relatively constant in the middle of the distribution. In contrast, it increases monotonically across the distribution for males: it is negative at the bottom and positive at the top. In the main, immigrants from Africa, Asia and the Middle East, Central and South America, and Eastern Europe suffer larger employment and earnings penalties, which are reduced as their length of stay increases. In contrast, immigrants from North America have a more favourable labour market experience.     

Who Gains from Restructuring the Post‐Soviet Transition Economies,and Why?

To explore the mixed economic results and huge distributional changes experienced by post‐Soviet economies, I set up a series of theoretical and numerical simulation models using an approach based upon heterogeneous firms, where ‘reform’ means closure of inefficient capacity. In the presence of significant costs to new firm entry and international capital mobility, restructuring and privatisation can lead to falls in GDP and real wages, while capital is transferred abroad. This situation can occur even under perfect competition, but is worse when industrial production is concentrated and trade costs are high. By contrast, workers can gain when costs of establishing new firms are low, and/or when the inefficient industries are capital‐intensive. For countries with high costs of firm set‐up and of trade, capital controls may be justified to protect wages.     

Non-traded Goods,Technical Progress and Wages

We use a general equilibrium model of trade to show that technical improvement may indeed cause a fall in the wages of unskilled workers. Under some modest conditions, the wages of skilled workers may go down too.

Do UK Higher Education Students Overestimate Their Starting Salary?*

The wage expectations of university students have relevance for human capital theory, models of student enrolment, and public policy on the provision of higher education. However, these expectations have been the subject of relatively little research in European countries, with no contemporary evidence available in the UK. There has also been little consideration in the literature thus far of how much estimates may be biased by non‐response and sample selection. This paper thus makes an original contribution to the literature by comparing UK undergraduate students' wage expectations with the actual wages earned by the same cohort on graduation, after attempting to correct for the aforementioned statistical issues in terms of observable characteristics. In contrast to other European studies, I conclude that, on average, full‐time students overestimate their starting salary. Yet I also find substantial variation in the extent of overestimation between different subgroups.     

Endogenous business cycle propagation and the persistence problem: The role of labor-market frictions

Contrasting sharply with a recent trend in DSGE modeling, we propose a business cycle model where frictions and shocks are chosen with parsimony. The model emphasizes a few labor-market frictions and shocks to monetary policy and technology. The model, estimated from U.S. quarterly postwar data, accounts well for important differences in the serial correlation of the growth rates of aggregate quantities, the size of aggregate fluctuations and key comovements, including the correlation between hours and labor productivity. Despite its simplicity, the model offers an answer to the persistence problem (Chari et al., 2000) that does not rely on multiple frictions and adjustment lags or ad hoc backward-looking components. We conclude modern DSGE models need not embed large batteries of frictions and shocks to account for the salient features of postwar business cycles.
