    Abstract: Social media enable promising new approaches to measuring economic activity and analyzing economic behavior at high frequency and in real time using information independent from standard survey and administrative sources. This paper uses data from Twitter to create indexes of job loss, job search, and job posting. Signals are derived by counting job-related phrases in Tweets such as “lost my job.” The social media indexes are constructed from the principal components of these signals. The University of Michigan Social Media Job Loss Index tracks initial claims for unemployment insurance at medium and high frequencies and predicts 15 to 20 percent of the variance of the prediction error of the consensus forecast for initial claims. The social media indexes provide real-time indicators of events such as Hurricane Sandy and the 2013 government shutdown. Comparing the job loss index with the search and posting indexes indicates that the Beveridge Curve has been shifting inward since 2011. The University of Michigan Social Media Job Loss index is update weekly and is available at http://econprediction.eecs.umich.edu/.

  2. By: Ajay Agrawal; John McHale; Alexander Oettl
    Abstract: The growing peer effects literature pays particular attention to the role of stars. We decompose the causal effect of hiring a star in terms of the productivity impact on: 1) co-located incumbents and 2) new recruits. Using longitudinal university department-level data we report that hiring a star does not increase overall incumbent productivity, although this aggregate effect hides offsetting effects on related (positive) versus unrelated (negative) colleagues. However, the primary impact comes from an increase in the average quality of subsequent recruits. This is most pronounced at mid-ranked institutions, suggesting implications for the socially optimal spatial organization of talent.

    Abstract: In this paper we examine the link between wage inequality and consumption inequality using a life cycle model that incorporates household consumption and family labour supply decisions. We derive analytical expressions based on approximations for the dynamics of consumption, hours, and earnings of two earners in the presence of correlated wage shocks, non-separability and asset accumulation decisions. We show how the model can be estimated and identified using panel data for hours, earnings, assets and consumption. We focus on the importance of family labour supply as an insurance mechanism to wage shocks and find strong evidence of smoothing of male’s and female’s permanent shocks to wages. Once family labour supply, assets and taxes are properly accounted for there is little evidence of additional insurance. JEL Classification: D11, D12, D31, D91

    Abstract: Although it seems evident that occupations affect health, effect estimates are scarce. We use a job characteristics matrix linked to German longitudinal data spanning 26 years to characterize occupations by their physical and psychosocial burdens. Employing a dynamic model to control for factors that simultaneously affect health and selection into occupations, we find that manual work and low job control both have a substantial negative effect on health that increases with age. The effects of late career exposure to high physical demands and low job control are comparable to a health deterioration due to aging 12 and 19 months, respectively.

    Abstract: Agricultural and other physically demanding sectors are important sources of growth in developing countries but prevalent diseases such as malaria adversely impact the productivity, labor supply, and occupational choice of workers in these sectors by reducing physical capacity. This study identifies the impact of malaria on worker earnings, labor supply, and daily productivity by randomizing the temporal order at which piece-rate workers at a large sugarcane plantation in Nigeria are offered malaria testing and treatment. The results indicate a significant and substantial intent to treat effect of the intervention – the offer of a workplace based malaria testing and treatment program increases worker earnings by approximately 10% over the weeks following the mobile clinic visit. The study further investigates the effect of health information by contrasting program effects by workers revealed health status. For workers who test positive for malaria, the treatment of illness increases labor supply, leading to higher earnings. For workers who test negative, and especially for those workers most likely to be surprised by the healthy diagnosis, the health information also leads to increased earnings via increased productivity. Possible mechanisms for this response include selection into higher return occupations as a result of changes in the perceived cost of effort. A model of the worker labor decision that includes health perceptions in the decision to supply effort suggests that, in endemic settings with poor quality health services, inaccurate health perceptions may lead workers to misallocate labor thus resulting in sub-optimal production and occupational choice. The results underline the importance of medical treatment but also of access to improved information about one’s health status, as the absence of either may lead workers to deliver lower than optimal effort levels in lower return occupations.

    Abstract: This paper examines the relationship between employment risk and job-seeker performance. To induce exogenous variation in employment risk, the outside options for job seekers undergoing a real recruitment process were randomized by assigning them a 0, 1, 5, 50, 75, or 100 percent chance of real alternative employment of the same duration and wage as the jobs for which they were applying. The findings show that job-seeker performance is highest and effort is lowest among those assigned the lowest employment risk (a guaranteed alternative job), and performance is lowest and effort highest among those facing the highest employment risk (those without any job guarantee). Moreover, a nonlinear relationship exists between employment risk and performance.

    Abstract: Immigrants may complement native workers, allow reallocation by skill in the firm and lower costs. These effects could be beneficial for the firm and increase its productivity and profits. However not all firmes use immigrants. Allowing firms to have differential fixed cost in hiring immigrants, because of different information and access to their network, we analyze the impact of an increase in local supply of immigrants on firms' immigrant employment and productivity. Using micro-level data on French firms during the period 1995-2005, we show that a supply-driven increase in foreign born workers in a department (location) increases the productivity of firms in that department. We also find that this effect is significantly stronger for firms with initially low (or zero) level of foreign employment. Those are also the firms whose share of immigrants increases the most. We also find that the positive productivity effect of immigrants is associated with faster growth of capital and improved export performances (for extensive and intensive margin) of the firms. While these outcomes depend on the firm share of immigrants in employment we find a positive effect of immigration on wages of natives and on specialization of natives in complex occupations that is common to all firms in the district. Supply-driven increase in foreign born workers in a department (location) implies a re-allocation of native workers towards communication and cognitive intensive tasks.

    Abstract: This paper measures the impact of wage zones – minimum wage differentials at the province level – on Italy's local labor markets during the 1950s. Using a spatial regression discontinuity design, it finds that for the industrial sectors covered under wage zones there was an increase in employment when one crossed the border from a high-wage province into a low-wage one; the effect diminished, however, as the distance from the boundary increased. The paper also illustrates that the impact on the overall (non-farm) private sector, which includes both covered and uncovered sectors, was basically zero. On balance, the scheme generated some reallocation of economic activity, albeit confined to areas close to the province border.

    Abstract: In 2010, only 19 percent of individuals ages 50-58 whose household incomes were less than 300 percent of the poverty line participated in a pension of any kind at their current jobs, compared to 56 percent of those above 300 percent of poverty. This paper investigates this pension gap. In particular, we decompose the pension participation rate into its four elements in order to compare coverage between higher- and lower-income individuals: 1) the fraction of people who are currently working (the employment rate); 2) the fraction of workers who are in firms that offer pension benefits to at least some workers (the offer rate); 3) the fraction of workers who are eligible for pension benefits, conditional on being in a firm where it is offered (the eligibility rate); and 4) the fraction of workers who enroll in a pension plan when they are eligible (the take-up rate). We find that the substantial pension gap between higher- and lower-income individuals is driven primarily by the lower-income group’s lower employment rate and the smaller probability of working for an employer that offers pensions; when lower-income workers do have a pension plan at work, their eligibility and take-up rates are nearly equivalent to higher-income workers. We also find that the factors associated with a higher value for each element of pension participation are very consistent: higher education and income, previous pension history, and job characteristics including firm size, occupation, job tenure, and union status. Together, these findings suggest that policies such as automatic enrollment that focus on pension eligibility or take-up are unlikely to close the pension coverage gap between older, lower-income individuals and their higher-income contemporaries; instead, greater pension participation requires more jobs and, in particular, more “good jobs.”

    Abstract: The current paper is a comparative analysis of employee participation in organisational governance in Italy and Australia. Cultural values determine the expression of institutional configurations, and to this end, we have adopted Hall and Soskice's Varieties of Capitalism and the Theory of the Firm as informing theoretical frameworks for our comparative study. Hall and Soskice represent Italy as a hybrid economy, and Australia as a liberal market lead economy. The main theoretical contribution of our paper is twofold. First, we hypothesize that the Australian Liberal Market Economic Configuration offers fewer opportunities for employee participation in organisational governance. Second, we critique mainstream Theory of the Firm on the ground that it is inadequate in explaining the phenomenon of employee participation across both economic configurations. We tested our hypotheses on some crucial institutional dimensions: (i) the role of the industrial relations system; (ii) the nature of corporate law; (iii) and the relative diffusion of different organisational forms with participative vis à vis exclusionary governance (although we acknowledge that participatory organisational forms are rare in both Italy and Australia) . We find support for differential facilitation of employee participation across Australian LME and Italian Hybrid economies.

    Abstract: To test how practice interruptions affect worker productivity, we estimate how temporal breaks affect surgeons’ performance of coronary artery bypass grafting (CABG). Using a sample of 188 surgeons who performed 56,315 CABG procedures in Pennsylvania between 2006 and 2010, we find that a surgeon’s additional day away from the operating room raised patients’ inpatient mortality risk by up to 0.067 percentage points (2.4% relative effect) but reduced total hospitalization costs by up to 0.59 percentage points. In analyses of 93 high-volume surgeons treating 9,853 patients admitted via an emergency department, where temporal distance effects are most plausibly exogenous, an additional day away raised mortality risk by 0.398 percentage points (11.4% relative effect) but reduced cost by up to 1.396 percentage points. These estimates imply a cost per life-year saved ranging from $7,871 to $18,500, rendering additional treatment intensity within surgery cost-effective at conventional cutoffs. Our findings are consistent with the hypothesis that after returning from temporal breaks surgeons may be less likely to recognize and address life-threatening complications, in turn reducing resource use. This form of human capital loss would explain the decrease in worker productivity and the simultaneous reduction in input use.
