A new consensus-based unemployment indicator

In this study we present a novel approach to measure the level of consensus among agents’ expectations. The proposed framework allows us to design a positional indicator that gives the percentage of agreement between survey expectations. While other aggregation methods such as the balance, which is constructed as the difference between the percentages of respondents giving positive and negative replies, explicitly omit the neutral information, the proposed metric allows synthesizing the information coming from all response categories, including the percentage of respondents who do not expect any change. In order to assess the performance of the proposed measure of consensus, we compare its ability to track the evolution of unemployment to that of the balance in eight European countries. With this aim, we scale both measures to generate one-period ahead forecasts of the unemployment rate. We find that the consensus-based unemployment indicator outperforms the balance in all countries except Denmark and Sweden, which suggests that the level of agreement among agents’ expectations is a good predictor of unemployment.     

Optimal taxation and redistribution in an OLG model with unemployment

This paper concerns redistribution via nonlinear income taxation in an overlapping generations model with two ability-types. We assume that the wage rates are determined by bargaining between unions and firms, meaning that the equilibrium is characterized by involuntary unemployment. We show that the policy instruments that are used to calculate the marginal labor income tax rate for each ability-type give rise to intertemporal tax base effects. In addition, since the relationship between the employment and the capital stock implies intertemporal production inefficiency at the second best optimum, imperfect competition in the labor market may itself justify capital income taxation.      

Informality,public employment and employment protection in developing countries

This paper proposes an equilibrium matching model for developing countries’ labor markets where the interaction between public, formal private and informal private sectors are taken into account. Theoretical analysis shows that gains from reforms aiming at liberalizing formal labor markets can be annulled by shifts in the public sector employment and wage policies. Since the public sector accounts for a substantial share of employment in developing countries, this approach is crucial to understand the main labor market outcomes of such economies. Wages offered by the public sector increase the outside option value of the workers during the bargaining processes in the formal and informal sectors. It becomes more profitable for workers to search on-the-job, in order to move to these more attractive and more stable types of jobs. The public sector therefore acts as an additional tax for the formal private firms. Using data on workers’ flows from Egypt, we show empirically and theoretically that the liberalization of labor markets plays against informal employment by increasing the profitability, and hence job creations, of formal jobs. The latter effect is however dampened or even sometimes nullified by the increase of the offered wages in the public sector observed at the same time.     

Unemployment,wages and pensions

Empirical evidence has shown the existence of a negative relationship between the rates of unemployment and real wages. If pensions are computed according to the wages that workers have contributed, then the unemployment rates during working life may also influence the pensions to which they are entitled. Using data from 2005 to 2012 for the Spanish social security system, we estimate that the unemployment elasticity of real pension is ?0.135. A 1% increase in unemployment rate is associated with a reduction in pension equal to 0.135%. In ‘normal times’, this value could be considered modest, but the Great Recession has increased dramatically the rate of unemployment. In 2012, the rate of unemployment in Spain had increased to 25.7% and in 2015, it had diminished to 20.9%. It is estimated that unemployment rate will not be returned to figures existing before the crisis until middle of the next decade. Moreover, the current reforms in social security systems could interact with the future effects of the current rates of unemployment and cause future pensions to be significantly lower than those estimated by individuals. The economic welfare of the future cohorts of retirees would then be significantly worsened.     

Regional and gender differentials in the persistence of unemployment in Europe

The persistence of unemployment increased during the recent great recession in many European countries, although with diversified impacts. We therefore analyse such impacts in four European countries – Italy, Spain, France and the UK – which represent different institutional frameworks and may reflect the so-called continental European and Anglo-Saxon frameworks. We analyse the determinants of unemployment persistence using individual-level data from the European Union Statistics on Income and Living Conditions (EU-SILC) panel for the period 2007–2013. These data enable us to take into account initial conditions and state dependence in addition to individual and household characteristics. We focus on gender and regional effects, which have a strong impact on the persistence in the state of unemployment. We find that gender gap is significant in Italy and the UK, implying that male workers show a higher probability of remaining unemployed. In Italy, such a pattern is due to the worsening of male workers’ conditions during the crisis, whereas in the UK, male workers show higher unemployment rates than women. Regional effects are significant in all countries analysed and underline a relevant structural factor that should be addressed on policy grounds in Europe. Such effects are greater in Spain and Italy.     

技术进步对中国就业影响的实证分析:1978—2006

技术进步对就业具有双重影响,一定时期内技术进步的就业效应并不明确。本文将TFP分解为纯技术进步率和技术效率的提高,运用1978—2006年的时间序列数据,分别分析了纯技术进步率和技术效率的提高对我国就业的影响。本文的研究发现,纯技术进步对就业具有比较显著的负效应,当期技术效率的改善对就业没有显著影响,而滞后期技术效率的改善却对就业量的增加具有负效应;经济的高速增长对我国就业总量的增加具有明显的正效应。因此,保持经济的高速增长对我国就业具有十分重要的意义。     

Tariffs,trade and unemployment in a disequilibrium model: issues and policies

This paper studies the disequilibrium transition process engaged by increased openness to trade, and the effect of institutions, market behaviors and economic policies on that transition. The issue is analyzed with a simple two country (north and south), two goods model, amended in order to take into account the time dimension of both the production and the decision processes. Investigating the consequences of a tariff decrease by means of numerical simulations, we show to what extent wage and price setting, and the degree of tightness of monetary policy affect the outcome of the disequilibrium process. The main result is that capturing the gains associated with international trade requires market behaviors and economic policies, which are rather different from what is usually prescribed.

失业风险预警系统研究

基于我国29年的历史数据,采用BP神经网络模型对我国的失业风险预警问题进行研究。结果表明,神经网络方法在失业风险系统中具有优良的预警效果,其对失业风险综合警情值的预测误差小于3％。相对于景气分析预测法、时间序列分析、灰色预测模型以及回归预测模型等技术,神经网络方法不仅具有良好的预测精度,同时还具备较强的容错能力和泛化能力。因此,在构建我国的失业风险预警系统中,神经网络模型应该是一种被优先考虑的方法。     

The long-run Phillips curve and non-stationary inflation

Modern theories of inflation incorporate a vertical long-run Phillips curve and are usually estimated using techniques that ignore the non-stationary behaviour of inflation. Consequently, the estimates obtained are imprecise and unable to test the veracity of a vertical long-run Phillips curve. We estimate a Phillips curve model taking into account the non-stationary properties in inflation and identify a small but significant positive relationship between inflation and unemployment. The results also provide some evidence that the trade-off between inflation and the rate of unemployment in the short-run worsens as the mean rate of inflation increases.
