Wage rigidity and job creation

Recent research in macroeconomics emphasizes the role of wage rigidity in accounting for the volatility of unemployment fluctuations. We use worker-level data from the CPS to measure the sensitivity of wages of newly hired workers to changes in aggregate labor market conditions. The wage of new hires, unlike the aggregate wage, is volatile and responds almost one-to-one to changes in labor productivity. We conclude that there is little evidence for wage rigidity in the data.     

Time-dependent or state-dependent wage-setting? Evidence from periods of macroeconomic instability

Administrative data on monthly wages in Iceland during 1998–2010 provide new insight into nominal wage rigidity. Unlike the data used in previous work, ours have a higher frequency, minimal measurement error, and a long sample including a period of substantial macroeconomic instability. We find that the monthly frequency of nominal wage changes is 13 percent. Although nominal wage cuts are rare, their frequency rises following a large macroeconomic shock. Timing of wage changes is both time-dependent and state-dependent: we find evidence of synchronization of adjustment and contracts of fixed duration, but also that inflation and unemployment over the wage spell affect the timing of adjustment.     

Real price and wage rigidities with matching frictions

Frictional unemployment means that workers, for some time, are a firm-specific factor of production. This paper models the resulting interaction of wage bargaining and price setting at the firm level in a New Keynesian model with labor market matching frictions. Real rigidities arise and the labor share ceases to be a good proxy for marginal costs. The model replicates the impulse responses of an SVAR for U.S. data better than alternatives in which the real rigidities arising at the firm level are absent. In addition, it implies reasonably low degrees of nominal rigidity whereas the alternatives do not. The interaction of wage and price setting at the firm level is important for the macroeconomic dynamics.     

Performance Volatility and Wage Elasticity: An Examination of Listed Chinese A-share Enterprises

The management of future financial risk on the part of managers and changes in firm finances are two of the fundamental reasons for upward and downward rigidity of wages. The proxy variable for firm financial risk is volatility, the past performance of which is among the principal indicators of wage rigidity. In firms whose current performance is on the upswing, the greater the volatility in past performance, the smaller the elasticity ratio and the more acute the upward rigidity; the more stable past performance, the larger the elasticity ratio and the more acute the upward elasticity. In firms in which current performance is declining, greater past performance volatility leads to a larger elasticity ratio and more acute downward rigidity, whereas more stable such performance leads to a smaller elasticity ratio and more acute downward rigidity.     

Labour taxation,job creation and job destruction—Focusing on the role of wage setting

We study the effects of labour taxation in a search equilibrium model with endogenous job destruction, embedding three alternative models of wage setting: Nash bargain, monopoly union and efficiency wages. Tax policy implications vary considerably depending on the wage setting model and indexation of unemployment benefits. If wage setting is based on bargaining, a pure increase in the tax progression reduces unemployment, improves the relative position of low-income workers and facilitates the emergence of low-productivity jobs. However, this comes at the cost of reduced efficiency partly owing to lower average productivity. JEL Code J30, J51, J64, H24     

Search and matching frictions and optimal monetary policy

A recent literature has merged the New Keynesian and the search and matching frameworks, which has allowed the former to analyze the joint dynamics of unemployment and inflation. This paper analyzes optimal monetary policy in this kind of hybrid framework. I show that zero inflation is optimal when all wages are Nash bargained in every period and the economy's steady state is efficient. In the more realistic case in which nominal wage bargaining is staggered, a case against price stability arises: in response to real shocks, the central bank should use price inflation so as to avoid excessive unemployment volatility and excessive dispersion in hiring rates. For a plausible calibration, the welfare loss under the zero inflation policy is about three times as large as under the optimal policy.     

Comment on: “Inflation dynamics with search frictions: A structural econometric analysis” by Krause, Lopez-Salido and Lubik

The implications of search frictions on the inflation dynamics are shown here for the case with wage adjustments typically belonging to the New Keynesian model, not to the Mortensen–Pissarides framework. In that model variant, I identify the role of search frictions by an additional term entering the slope coefficient of the inflation equation. After a numerical exercise, I find results that are in line with those obtained by Krause et al. [2008. Inflation dynamics with search frictions: a structural econometric analysis. Journal of Monetary Economics 55, doi:10.1016/j.jmoneco.2008.05.003.].     

The valuation-relevance of the foreign translation adjustment: The effect of barriers to entry

We examine the economic effects of barriers to entry on the association between foreign currency translation adjustments and the stock returns of multinational firms operating in the manufacturing and service industries. Firms that are innovation leaders, that is, firms that are research and development (R&D) intensive and firms with high foreign asset intensity (i.e., asset-intensive firms), are our proxies for firms operating in environments with barriers to entry (i.e., environments in which competition is less intense). We hypothesize and find that foreign currency translation adjustments are positively associated with abnormal stock returns for firms operating in environments with barriers to entry in both manufacturing and service industries. This finding highlights the importance of assessing the valuation-relevance of foreign currency translation adjustments by considering the economic contexts of foreign currency movements. Overall, the evidence shows that the accounting rules governing foreign currency translations generally produce results consistent with the economic effects of foreign exchange rate changes.     

Labor market reform and price stability: An application to the Euro Area

Central bankers frequently suggest that labor market reform may be beneficial for inflation management. This paper investigates this topic by simulating the effects of reductions in firing costs and unemployment benefits on inflation volatility in the Euro Area, using an estimated New Keynesian model with search and matching frictions. Qualitatively, changes in labor market policies alter the volatility of inflation in response to shocks, by affecting the volatility of the three components of real marginal costs (hiring costs, firing costs and wage costs). Quantitatively, we find, however, that neither policy is likely to have an important effect on inflation volatility, due to the small contribution of hiring and firing costs to inflation dynamics.     

Transitions in the German labor market: Structure and crisis

Since the so-called Hartz IV reforms around 2005 and during the global crisis of 2008/2009, the German labor market featured mainly declining unemployment rates. We develop a search and matching model with heterogeneous skills to explore the role of structural and cyclical policies for this performance. Calibrating unemployment benefits to approximate legislation before and after the reforms, we find a large reduction in unemployment and its duration, with the transition concluding after about three years. During the crisis, the extended use of short-time labor subsidies that prevent jobs from being destroyed is likely to have prevented strong increases in unemployment.     

Labor tax reform, unemployment, and search

A key obstacle to reducing payroll taxes in many industrialized and transition countries is the direct revenue loss to the government that it implies. This paper studies a simple and practical labor tax reform of reducing a payroll tax and increasing a progressive wage tax that keeps the marginal tax wedge unchanged. Such a strategy increases employment, reduces the equilibrium unemployment rate, and increases public revenue as long as workers do not have all the bargaining power in wage negotiations. Moreover, welfare rises if workers’ bargaining power is sufficiently large to exceed a critical value determined by the second-best Hosios condition.      

劳动力成本与利润差异对制造业升级的影响研究

引入单位劳动力成本和人均利润,考量劳动力成本与利润影响制造业升级的效应。结果表明：样本期间内虽然劳动力成本快速上涨,但劳动生产率增速更快,制造业整体单位劳动力成本没有上升,且有小幅下降,劳动密集型制造业仍有一定综合成本优势,但其人均利润低于制造业整体水平,比重总体下降,发展后劲不足,须转型升级;资本密集型虽然利润率相对较低,但人均利润为最高,比重不断上升,仍应是当前发展的重点;技术密集型比较优势不明显,急需突破核心技术,提高综合国际竞争力。

加入工会能有效改善职工工作条件吗

工会是劳动力市场的重要调节机制。本文基于中国社会综合调查数据,采用倾向值匹配方法来控制样本选择偏误,并利用自抽样进行统计推断,以克服小样本偏误,试图回答工会组织对职工工作条件的影响。研究结果显示:整体而言,加入工会可以明显地改善职工的工作条件。进一步研究发现,加入工会对体制内部门职工的工作条件有显著的改善作用,而对体制外部门职工工作条件的改善作用并不明显。此外,工会对职工工作条件的改善作用会随着市场化程度的影响而逐渐弱化。上述结果意味着中国工会组织对收入机制具有影响作用,通过夏普利值过程的回归分解发现,工会对职工小时收入差距和年收入差距的贡献率分别为4.53%和9.77%。     

Do time-varying risk premiums explain labor market performance?

Within the standard search and matching model, time-to-build implies that high aggregate risk premiums should forecast low employment growth in the short run but high employment growth in the long run. If there is also time-to-plan, high risk premiums should forecast low net hiring rates in the short run but high net hiring rates in the long run. Our evidence indicates two-quarter time-to-build in the aggregate payroll data, no time-to-plan in the aggregate hiring data, but two-quarter time-to-plan in the job creation data for manufacturing firms. High payroll growth and high net job creation rate in manufacturing also forecast low stock market excess returns at business cycle frequencies.

Crowding out or crowding in? Correlations of spending components within and across countries

Using data for a sample of advanced and developing countries, the paper studies variation in the transmission of shocks from public and private components of spending to the macro-economy and distinguishes between the effects of expansionary and contractionary shocks. The aim is to study the extent by which capacity and propagation channels would reinforce or mitigate the cyclical responses of macroeconomic variables to expansionary and contractionary shocks to private and public components of spending. Further, the evidence will spell out the extent of co-movement in the variables’ adjustments to the specific shock across the macro economy. The bulk of the time-series evidence indicates more pervasive effects on growth in connection to private consumption across advanced countries. In contrast, the growth effects of public consumption are more pervasive across developing countries. Across the two groups, the growth impact of public consumption is more pronounced, compared to that of public investment. Further, the inflationary effects are pronounced with respect to public and private spending shocks. In general, the limited statistically significant real time-series evidence attests to conflicting channels with respect to variables’ adjustments to one shock and inadequate co-movement in the transmission mechanism of various public and private spending shocks in many countries.
