The Returns to Nursing: Evidence from a Parental-Leave Program

AbstractIn this article, we quantify the effects of nurses on health care delivery and patient health in the context of an unintended and policy-induced nurse shortage. Our empirical strategy takes advantage of a parental-leave program in Denmark, which offered any parent the opportunity to take up to one year’s absence per child aged 0–8. Combining the policy variation with administrative employer–employee match data, we document substantial program take-up among nurses, who could not be replaced on net despite public education and immigration expansion efforts to mitigate the employment effects. We find that the parental leave program reduced hospital and nursing home nurse employment by 15% and 10%, respectively. Using detailed patient health records, we find detrimental effects on hospital-care delivery as indicated by a large increase in 30-day readmission rates among acute myocardial infarction patients. We find no evidence for an increase in hospital mortality. In nursing homes, we estimate a large increase in mortality.

Decomposition of co-worker wage gains

Abstract We address the presence, magnitude, and composition of wage gains related to former co-workers and discuss the mechanisms that could explain their existence. Using Hungarian linked employer–employee administrative data and proxying actual co-workership with overlapping work histories, we show that the overall wage gain attributable to former co-workers consists of multiple elements: a contact-specific, an individual-specific, a firm-specific and a match-specific component. Former co-workers, besides the direct effect of their presence, may funnel individuals into high-paying firms, enhance the sorting of good quality workers into firms, and may contribute to the creation of better employer–employee matches. By introducing and applying a wage-decomposition technique, we demonstrate that there are non-negligible differences between linked and market hires in all empirically separable wage elements. By focusing on specific scenarios, we provide additional empirical evidence in favor of employee referral and information transmission as the main drivers of co-worker gains.

Worker flows, reallocation dynamics, and firm productivity: new evidence from longitudinal matched employer–employee data

AbstractThis article investigates the impact of the worker flows of a firm on productivity by using unique longitudinal matched employer–employee data. The analysis has split a firm’s total worker flows into three components: workers’ replacements (excess worker flows), hirings introduced to increase the firm’s employment level (net hirings), and separations of workers intended to decrease the firm’s workforce (net separations). This has allowed the impact of workers’ replacements, which represent the most prominent and compelling feature of worker mobility, to be isolated from the other two components. Endogeneity has been dealt with by using a modified version of Ackerberg et al.'s (2015, Econometrica, 83(6), 2411–2451) control function method, which explicitly accounts for firm-fixed effects. The main findings are that (i) excess flows have an inverted U-shape impact on productivity, (ii) net hirings foster firm productivity, and (iii) net separations damage it. The impacts are heterogeneous and vary widely on the basis of the types of replacements, the categories of workers involved, and the types of firms experiencing such flows. Overall, the findings of this article highlight the importance of reallocation dynamics to obtain better employer–employee matches, and call for a reconsideration of policies concerning the flexibility of the labor market.

History dependence in wages and cyclical selection: Evidence from Germany

Using administrative employer-employee data from Germany, we investigate the behavior of individual wages over the business cycle. We present evidence that both contractual wage arrangements and cyclical match quality are a key feature of the German labor market. We show that parts of the excess wage cyclicality of new hires discussed by the literature can be explained by cyclical job ladder movements in match quality of new hires from employment. Guided by the literature of job reassignments, we additionally allow for variation in the match quality within an employer-employee match. Besides support for job-specific contracts, our novel main results show that much of the excess wage cyclicality of job changers can be explained by occupation switching workers.

Migrants and Informal Casual Labour Markets

Internal migration in India is estimated to be at around 100 million people and short-term seasonal migration for work is estimated to vary between 80 and 140 million. Employers may benefit from the increase in the supply of labour, and middle-class households may benefit from the lower price of household services provided by the migrants and their families. Local residents with comparable skills to those of migrants may find that they have to compete for jobs in the labour market. Many regions implicitly differentially prioritize the interests of local residents and of migrants whilst filling vacant jobs, resulting in a tradeoff between welfare rights and openness to migration. Migrants take into account the tradeoffs of poor working conditions and unwritten and unenforceable contracts, with the higher income in the destination region, and all considered migrate. We provide a framework for understanding this socio-economic outcome. In many urban contexts, migrants and other low-skilled workers gather at some focal point such as a busy market place or crossroad in the morning and meet with potential employers who negotiate the type of work to be performed, the wage, and the number of hours that the worker has to work. Surprisingly, there has been a paucity of research on the employer–employee match in the daily urban casual labour market. Working days are usually long—between 12 and 14 h in many instances—and the wage and working conditions are usually negotiated. The market wherein the bargain takes place is a flexible labour market where workers can be replaced by the employer at a minimal cost to the employer. In most of such contracts workers report that they have been cheated and face harassment. The requirements for complete contracting are severe in this market. It is difficult ex ante to specify what constitutes a satisfactory performance of the contract (as it is difficult to record and measure performance), and accordingly, it is difficult to enforce the contract via a third party. This leads to opportunism as the employer holds up the worker by requiring further responsibilities such as longer hours of work to be undertaken that were not negotiated in the first place. We postulate a bargaining approach to unearth the role of regulation and the determination of wages and work conditions in the informal casual labour market.

Job mobility in Turkey

The degree and quality of job mobility is an important factor of optimal allocation of resources and growth in an economy. Job mobility facilitates productive employer-employee matches. In that respect, job mobility allows employees to work in industries which suit their skills and enables earning gains. It also supports industry level productivity gains by providing shift of employment from less productive firms to more productive ones. In this study, a descriptive analysis of job mobility is conducted using Entrepreneurship Information System data. The results suggest that job mobility is higher among young and men. In addition, more than half of the job movers switch to jobs in bigger, more productive and more profitable firms. Job mobility is intensive within manufacturing and trade-transportation industries and employees in mining, construction, public administration, education and health industries are more likely to switch to jobs in other industries. Finally, the determinants of job mobility between regions are analyzed and a positive relation between internal migration and intra-regional job mobility is found.

"I want to break free". The role of working conditions on retirement expectations and decisions.

We investigate the role of working conditions on the desire to retire as soon as possible and on the probability of transition from employment to either full or partial retirement, using different measures of work quality. We find that low work quality strongly correlates with the desire to retire as soon as possible of "young-old" workers. This might be explained by the deterioration of employer-employee match with age due to reduced incentives for firms to invest in training and work practises that enhance workability of their senior workers. When we move from intentions to decisions, the role of work quality is less clear-cut and it mainly plays a role in the transitions from employment to full retirement.

Is it All About Access? Perceived Access to Occupational Pensions in Germany

This paper provides an empirical analysis of what determines access to occupational pensions as perceived by workers. We investigate this issue in Germany, where workers have the legal right to an occupational pension since 2001, but many might lack the incentive or the ability to gather and process the relevant information to make use of their right. In particular, if workers rely exclusively on the information available at their firm, employers will continue to regulate access despite workers' rights. Our findings suggest that the current regulation in Germany has not resolved the problem of workers' ignorance of their access to occupational pensions. Only about half the workers are aware of having access to an occupational pension. We find that there is important heterogeneity in workers' perceptions, and that this heterogeneity is directly related to worker and firm-side factors as well as outcomes of the employer-employee match. Distorted perceptions have important consequences for workers, policy makers and firms. Workers can only make optimal savings decisions if they are aware of their savings possibilities. Policy makers could help by making information material about occupational pensions mandatory and/or by defining standardised information. A low level of knowledge of employees might also be frustrating for employers, as this would suggest that workers do not appreciate their occupational pension, limiting the power of occupational pension as a Human Resources tool.

The cyclicality of effective wages within employer–employee matches in a rigid labor market

This study analyzes real wage cyclicality for male full-time workers within employer–employee matches in Germany over the period 1984–2004. Five different wage measures are compared: the standard hourly wage rate; hourly wage earnings including overtime and bonus pay; the effective wage, which takes into account unpaid overtime; and monthly earnings, with and without additional pay. None of the hourly wage measures exhibits cyclicality except for the group of salaried workers with unpaid overtime. Their effective wages show a strongly procyclical reaction to changes in unemployment. Despite acyclical wage rates, salaried workers without unpaid overtime experienced procyclical earnings movements if they had income from extra pay. Monthly earnings were also procyclical for hourly paid workers with overtime pay. These findings suggest that cyclical earnings movements are generated by variable pay components, such as bonuses and overtime pay, and by flexible working hours. The degree of earnings procyclicality revealed for the German labor market is comparable to the United States.

Labor Market Models of Worker and Firm Heterogeneity

Microeconomic data on individual firms and employer-employee matches reveal substantial and persistent dispersion in firm size, productivity, and average wage paid and a positive correlation between each pair. To the extent that intrinsic differences in firm productivity explain these facts, there are several important consequences. First, the reallocation of employment from less to more productive firms will yield efficiency gains. Second, workers will find it in their interest to seek out higher-paying employers. Recent research has provided support for both hypotheses. Third, the existence of worker and employer heterogeneity offers possible gains from sorting. However, because the problem of identifying the presence of sorting is model dependent, it is too early for conclusions about its significance.

The effect of collaboration network on inventors' job match, productivity and tenure

It has been argued in the economic literature that job search through informal job networks improves the employer–employee match quality. This paper argues that inventors' research collaboration networks reduce the uncertainty of firms about the match qualities of inventors prior to hiring. We estimate the effect of inventors' collaboration networks on their productivity and mobility using the U.S. patent application database. It is found that networked inventors are more productive and have longer tenure than non-networked inventors. The evidence from fixed-effect regressions shows that the higher productivity and longer tenure of networked inventors are not solely attributable to unobserved ability of inventors or unobserved characteristics of firms. These results are consistent with the job match hypothesis between inventors and firms through their collaboration networks.

These results are consistent with the job match hypothesis between inventors and firms through their collaboration networks.

The Cyclicality of Effective Wages Within Employer-Employee Matches: Evidence from German Panel Data

The Cyclicality of Effective Wages Within Employer-Employee Matches: Evidence from German Panel Data

The Cyclicality of Real Wages within Employer-Employee Matches

Using data from the Panel Study of Income Dynamics, the author examines the cyclicality of wages within employer-employee matches for the years 1970-91. Recent research on wage cyclicality has suggested that wages are very procyclical (tending to rise and fall with economic upturns and downturns), even for workers who remain with the same employer. The author finds, however, that the evidence for wage procyclicality within the matches he examines is rather weak except for the small group of workers who were paid by piece rate or commissions. Despite having acyclical wage rates, men who were paid hourly had earnings movements that were very procyclical. Salaries exhibited little cyclicality, but salaried workers who had income sources from bonuses, commissions, or overtime had procyclical earnings. The results suggest that the increasing prevalence of incentive-based pay will increase the procyclicality of wages within matches.

Real Wages over the Business Cycle: Evidence from Panel Data

One topic on which Keynes did not disagree with classical economists was the cyclical behavior of real wages. Keynes (1936) as well as various classical writers predicted that real wages should move countercyclically. Quoting the General Theory (p. 17): "in general an increase in employment can only occur through the accompaniment of a decline in real wages. Thus, I am not disputing this vital fact which the classical economists have (rightly) asserted as indefeasible." This prediction is based on the premise of competition and a given short-run capital stock. Increases in employment then correspond to more intensive use of capital and, through diminishing product, lower real wages. For this reason, evidence by Dunlop (1938) and Tarshis (1939) that real wages move procyclically was viewed as paradoxical. Both Dunlop and Tarshis based their findings on an observed positive correlation between real and money wages, which, given the procyclical movement of money wages, implies a positive correlation between
