Envy, leisure, and restrictions on working hours

Abstract.  We present a simple model of capital accumulation where agents care about their consumption relative to the consumption of other members of society, 'envy,' In this context we quantify the extent of the distortions and welfare costs associated with envy. Under conservative estimates of envy we find that the implied welfare losses are substantial. We explore the implications of alternative policy arrangements designed to minimize the effects of the consumption externality. Our results suggest that if the optimal tax policy is not politically feasible, restrictions on working hours provide an alternative tool to induce a market outcome that resembles the efficient allocation achieved under a benevolent central planner.

How working time reduction affects jobs and wages

In 1996, by law the maximum standard workweek in Portugal was reduced from 44 h to 40 h. We find that for workers involved this change reduced the job separation rate and increased hourly wages, keeping monthly earnings approximately constant. The working hours reduction also affected workers working less than 40 h per week; they were more likely to lose their job.     

Market wages,reservation wages,and retirement decisions

The paper is an empirical cross-section study of the retirement decisions of American white men between the ages of 58 and 67, predicated on the theoretical notion that an individual retires when his reservation wage exceeds his market wage. Reservation wages are derived from an explicit utility function in which the most critical taste parameter is assumed to vary both systematically and randomly across individuals. Market wages are derived from a standard wage equation adjusted to the special circumstances of older workers. The two equations are estimated jointly by maximum likelihood, which takes into account the potential selectivity bias inherent in the model (low-wage individuals tend to retire and cease reporting their market wage). The model is reasonably successful in predicting retirement decisions, and casts serious doubt on previous claims that the social security system induces many workers to retire earlier than they otherwise would. The normal effects of aging (on both market and reservation wages) and the incentives set up by private pension plans are estimated to be major causes of retirement.

Precautionary savings or working longer hours?

This paper quantifies the macroeconomic implications of the lack of insurance against idiosyncratic labor market risk. I show that in a model economy calibrated to observed individual level data, households make ample use of work effort as a consumption smoothing mechanism. As a consequence, aggregate consumption is 0.6% lower, work effort is 18% higher and labor productivity is 12% lower than they would be in a complete markets setting. Not surprisingly, the welfare benefits of moving towards complete markets are very large. Accounting for the whole transition to the new complete markets steady state I find the welfare costs of market incompleteness above 16% of individual lifetime consumption.     

The effects of minimum wages on the health of working teenagers

This article examines the effect of minimum wage increases on the self-reported health of teenage workers. We use a difference-in-differences estimation strategy and data from the Current Population Survey, and disaggregate the sample by race/ethnicity and gender to uncover the differential effects of changes in the minimum wage on health. We find that white women are more likely to report better health with a minimum wage increase while Hispanic men report worse health.     

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.     

Computers,skills and wages

Computer technology is most prominently used by skilled, high-wage workers. This suggests that computer use requires skills to take full advantage of the possibilities, which are particularly present among relatively skilled workers. This article develops a simple technology adoption model showing that the decision to adopt computer technology depends on (i) the tasks to be performed, (ii) the level of skill or education and (iii) the level of wages. Applying this model to British data, it is shown that the effect of wages and particular tasks on computer adoption is larger than the effect of skills on adoption. The estimates suggest that in Britain computer use is likely to be a matter of cost efficiency and not so much of workers’ skills.     

Coordination, matching, and wages

We analyse the coordination problem in the labour market by endogenizing the matching function and the wage share. Each firm posts a wage to maximize the expected profit, anticipating how the wage affects the expected number of applicants. In equilibrium workers apply to firms with mixed strategies, which generate coordination failure and persistent unemployment. We show how the wage share, unemployment, and the welfare loss from the coordination failure depend on the market tightness and the market size. The welfare loss from the coordination failure is as high as 7.5 per cent of potential output. JEL Classification: C78, J64
Les auteurs analysent le problème de la coordination dans le marché du travail en endogénéisant la fonction 'arrimage et la part des revenus qui va aux salaires. Chaque entreprise définit le niveau de salaire qui maximise ses profits anticipés, en tenant compte de l'effet de ce niveau de salaire sur le nombre des applications qu'elle peut anticiper. De même, les travailleurs font application auprès d'une entreprise à un salaire donné en tenant compte d'une certaine relation d'équivalence entre niveau de salaire et probabilité d'obtenir l'emploi. Voilà qui engendre incoordination et chômage persistant. On montre que la part des revenus qui revient aux salaires, le niveau de chômage, et les pertes de bien-être attribuables au manque de coordination dépendent de la taille du marché et du degré de rareté de la main d'oeuvre. Les pertes de bien-être attribuables au manque de coordination correspondent à quelques 7,5 pour-cent de la production potentielle.     

Growth,Death, and Taxes

Recent theories of endogenous growth suggest that changes in tax rates may permanently affect growth. However, attempts to quantify these growth effects have reached very different conclusions in spite of a common theoretical framework: the neoclassical growth model with human capital accumulation by infinitely lived households. This paper shows that a model which explicitly specifies human capital accumulation over the life-cycle provides sharper answers. In such a model, a plausible range for the growth effects of eliminating taxes in the United States is between 0.5 and 1.3 percentage points compared with 0 to 4 percentage points in the infinite horizon model. The much wider range found in the literature is due to two assumptions which are commonly viewed as innocuous simplifications but contrast sharply with traditional human capital theory: that households are infinitely lived and face constant point-in-time returns in human capital accumulation. The widely held view that long, finite horizons are closely approximated by infinite horizons is generally invalid. Abstracting from finite horizons leads to a systematic overstatement of the growth effects of taxes. Journal of Economic Literature Classification Numbers: J24, O41.     

Inflation,technological-knowledge bias,and wages

A detailed examination of wage data points to a wage polarization trend vis-à-vis the distribution of qualifications. Theoretically terms, this points to the need for modeling focused on the relevance of the direction of technological knowledge. To this end, we branched production into routine and non-routine tasks. In this way, the results produced positive relationships between the relative supply of skilled workers and the skill premium and between automation and wage polarization.     

Taxes,Strikes and Wages

A union and a firm bargain about wage increases. The firm possesses private information about its revenues. A two-period screening model is used to derive equilibrium wage demands by the union and to calculate measures of strike activity. Changes in wage demands and dispute probabilities due to alterations in various taxes are analysed. A more progressive income tax, a lower level of income taxes and higher payroll taxes reduce wages and strike activity. Hence, tax policy can be used not only to affect wages and employment, but lso to influence strike incidence.
