Supervision and monetary incentivesAllgulin, Magnus January 1999 (has links)
This thesis extends the standard shirking model of efficiency wages to a continuum of effort levels. The generalisation completely overturns previous intuitions. In particular, the characteristic feature of the earlier theory that monitoring and pay are substitute instruments for motivating workers, no longer exists. This is remarkable, since such a negative correlation has been used as the primary empirical test for the existence of efficiency wages. With a continuum of effort levels, the efficiency wage model can also more conveniently be compared with conventional linear incentive wages. The most frequently recurring objection against the efficiency wage model is that unemployed workers should offer to pay entrance fees. This criticism is responded to in a model with finitely many periods. It is shown that the per period worker rents associated with efficiency wages strongly diminishes with the number of periods. It is further argued that both bonds and entrance fees are inferior means of extracting the remaining worker rents compared to investments in firm specific human capital. Finally, the above refinements of the efficiency wage theory are translated to fit in the arena of environmental economics and government policy. The corresponding results establish a rationale for a government to subsidise polluting firms and explain why a command and control policy is preferable to market-based incentive schemes. / Diss.

Har du vad som krävs? : En jämförande studie av färdigheters betydelse för löner och sysselsättningFornwall, Anna, Paulsson, Emma January 2017 (has links)
I denna undersökning studeras betydelsen av färdigheterna läskunnighet, räknefärdighet och problemlösning på sysselsättning och lönenivå. Undersökningen fokuserar främst på att studera om färdigheterna hos kvinnor och utrikes födda har annorlunda påverkan än för befolkningen i helhet. Studien jämför resultaten mellan Sverige och Tyskland. Metoden som används är linjär multipel regressionsanalys med minsta kvadratmetoden. Resultaten visar att en individs färdigheter har större betydelse för var i lönefördelningen hen befinner sig än om hen är sysselsatt eller inte. Effekterna på lön är genomgående positiva för båda länderna, men större för Tyskland än för Sverige – vilket indikerar att avkastningen på färdigheter är större i Tyskland. Resultaten visar vidare att kvinnor har lägre löner än män i både Sverige och Tyskland, men skillnaderna är genomgående större i Sverige. Det finns även vissa indikationer på att utrikes födda har det något svårare att komma in på den svenska än den tyska arbetsmarknaden. / This study analyses the importance of the skills literacy, numeracy and problem solving on employment and earnings. The main focus of this study is particularly if the effects of skills within the groups ‘women’ and ‘foreign born’ differ from the population as a whole. The study compares the results between Sweden and Germany. The method used is multiple linear regression analysis using ordinary least squares. The results show that skills have a greater importance for an individuals placing in the wage distribution than for whether the individual is employed or not. The effects on wages are all through positive for both countries, but greater for Germany than Sweden – indicating that the return to skills is higher in Germany. The results further show that women’s wages are lower than men’s in both Sweden and Germany, but the gaps are larger in Sweden. There is also some evidence that foreign-born individuals have a harder time entering the Swedish labour market than the German.

Empirical studies on wages, firm performance and job turnoverHeyman, Fredrik January 2002 (has links)
This thesis consists of four self-contained studies in empirical labor economics. Micro data on both employers and workers are used to analyze the questions asked in the essays. By using disaggregated information, issues related to firm and individual heterogeneity can be studied.The first essay, The Impact of Temporary Contracts on Gross Job and Worker Flows (with Mahmood Arai), examines job and worker flow dynamics for temporary and permanent contracts. The micro approach to job flows concerns changes in employment at the plant or firm level. Data used in earlier research on gross labor flows do not allow for a distinction between different types of employment contracts (an exception is Abowd et al. (1999). This distinction is especially important in Europe since several European countries discriminate between permanent and temporary contracts in their employment legislation.The data contain quarterly information on the stock of permanent and temporary contracts, as well as direct information on hires and separations for permanent and temporary workers. The information is from a representative sample of around 10,000 Swedish private establishments.The results indicate that temporary contracts, covering only around 10 percent of all contracts, stand for half of all gross job (and worker) flows. This means that gross job (and worker) flow rates for temporary contracts are around 10 times larger than job (and worker) flows for permanent contracts. Our results imply that job reallocation associated with temporary contracts is acyclical in both manufacturing and non-manufacturing sectors. For permanent contracts, job reallocation only exhibits a countercyclical pattern in manufacturing, characterized by a low fraction of temporary contracts. Services employing a higher fraction of temporary contracts exhibit no cyclical pattern in job reallocation, implying that establishments in services use temporary contracts as an adjustment buffer and can adjust its labor input more smoothly.The share of temporary contracts varies with the industry structure and changes as a result of sectoral shifts. This implies that cross-country comparisons, as well as studies of the dynamics of job and worker flows, based on aggregated time-series data, can be distorted by the impact of the fraction of temporary labor on gross labor flows. This, in turn, makes the distinction between permanent and temporary contracts crucial in analyzing job and worker flows, especially when labor protection laws discriminate between short-and long-term employment contracts. The second essay, Wage Dispersion and Allocation of Jobs, investigates the relationship between job turnover and the distribution of wages. One possible explanation for similar labor reallocation rates across labor markets with very different employment-protection legislations is related to differences in wage setting institutions. Bertola and Rogerson (1997) argue that although job-security laws lead to lower job flows, their impact might be reduced if differences in wage-setting institutions have opposite effects. Bertola and Rogerson’s conclusion is that when labor protection laws and wages are jointly considered, the result might very well be that job flows in countries with high adjustment costs and a compressed wage structure mimic those in countries with low adjustment costs and decentralized wages.Using establishment data on job turnover and wages for a panel of around 10,000 establishments in the Swedish private sector, the relationship between wage compression and job reallocation is studied at the industry level.Estimating industry fixed-effects models for 14 two-digit industries yield results indicating large sector differences regarding the effect of the degree of wage dispersion on job reallocation. In accordance with the Bertola and Rogerson hypothesis, this effect is positive in the manufacturing sector. Running separate regressions for job creation and job destruction shows a negative and significant effect of wage dispersion on job destruction, whereas it is insignificant in the job-creation equation. These results are in accordance with wages being more rigid downwards than upwards. The quantitative effect of the impact of wage dispersion on job turnover is limited, however. A one standard deviation increase in wage dispersion reduces the total job reallocation by around 10 percent. Turning to the non-manufacturing sector, the Bertola and Rogerson hypothesis is not supported.Further results include (i) a strong positive effect of the industry-share of temporary employees on job reallocation and (ii) a negative relationship between the use of overtime and job turnover.In the third essay, Wages, Profits and Individual Unemployment Risk: Evidence from Matched Worker-Firm Data (with Mahmood Arai), the impact of firm performance on individual wages is studied. Several studies have found a positive and significant effect of profits on wages. The most widely suggested interpretation for this phenomenon is that employers and employees engage in rent-sharing, thereby splitting the profits created between themselves.The purpose of this study is to examine the extent of rent-sharing and the impact of individual and aggregated unemployment risk on wages of individual workers. We use a sample of over 170,000 Swedish employees for 1991 and 1995 matched with their employing firm’s profits and the unemployment registers. The matched data contain detailed information on individual characteristics, including their unemployment experience during 1992-1995 as well as annual profits as reported in the firms’ balance-sheet reports.The contribution of this paper is that it provides evidence on the wage determination, based on disaggregated individual and firm data dealing with the problems of firm and worker heterogeneity, and the endogeneity of profits. Our results imply positive effects of profits on wages, both in 1991 and 1995. The reported elasticities imply that the wage inequality in Sweden due to the spread in profits is as high as 13% of the mean wages in 1991, according to Lester’s range of pay. These correlations are robust for controlling for time-invariant unobserved individual- and firm characteristics.Using firm-reported short-term product market elasticity and the number of competitors as instruments for profits suggest Lester’s measure of wage inequality due to profits to be as high as 50% of the mean wages.Finally, we investigate the impact of individual heterogeneity with respect to unemployment risk that might also affect wages. We include the individuals’ unemployment event record in our regressions, and our results confirm that individuals with a higher unemployment risk also have lower wages. Including aggregated measures along with individual unemployment risk in our estimations show results suggesting that there exists a robust negative correlation between unemployment risk and wages at various aggregation levels.The final essay, Pay Inequality and Firm Performance: Evidence from Matched Employer-Employee Data, tests several implications from tournament models on the same matched employer-employee data set as in essay 3.According to a variety of theories, the wage distribution both within and between firms can have important effects on individual productivity and firm performance. One argument for high wage differentials, based on incentive effects, is found in Lazear and Rosen’s (1981) tournament theory. Higher wage differentials lead to higher individual effort, and are therefore productivity enhancing. This, in turn, suggests that there is a positive relationship between wage dispersion and productivity. The opposite relationship is found in theories stressing fairness and cooperation between co-workers.For white-collar workers, the results show a positive effect of intra-firm pay spread on firm performance for 1991 and 1995. This applies to different measures of wage dispersion, capturing both raw differences and differences corrected for the fact that part of the wage spread is due to differences in human capital accumulation. To take firm heterogeneity into account, difference equations are estimated on a panel of firms. Once more, consistent with tournament theory, a positive and significant effect of wage dispersion on profits is found. The results for managers are based on information on about 10,000 managers. For various measures of wage dispersion and specifications, a positive and significant association between managerial pay and profits is found. No support is found for the hypothesis of a positive relationship between the number of managers (contestants) and wage spread. Instead, the results show a negative and significant effect of the number of executives and pay spread among managers.Finally, consistent with tournament theory, higher wage dispersion is found in firms operating in volatile product markets characterized by a high degree of output uncertainty. / Diss.

Predictive analysis of organisational costs to achieve gender pay equity / Prediktiv analys av kostnaden för organisationer att uppnå jämställda löner mellan könenRohde, Oscar January 2022 (has links)
The gender pay gap has been a hot topic during the last decade and legislation regarding pay equity is increasing in Europe. Continuous work with gender pay equity is essential to avoid costly consequences. There are methods today to find unsubstantiated pay differences, but how could one predict the cost of fixing the pay gap? How can the one predict the cost of making an unequal pay structure equal? How may pay equity methods be explained to people not well-versed in mathematical reasoning? To investigate these questions, the study uses literature, simulations in Python, and a workshop to gather empirical data. Simulation is used to analyse different methods of closing the gender pay gap. The workshop was held at the pay equity SaaS company Pihr. Results suggest several methods to close the gender pay gap that vary in cost and perceived fairness. One can never be absolutely certain of the presence or absenceof gender discrimination, but one can make well-informed estimates using different methods of analysis. The results also suggest that pay equity methods should be explained using informal, non-mathematical words, with examples connected to real-world scenarios in a familiar context for the learner. / Lönegapet mellan män och kvinnor har senaste årtiondet varit ett omdiskuterat ämne och juridiska krav om jämställda löner har blivit alltmer förekommandei Europa. Att kontinuerligt arbeta för mer jämställda löner mellan könen är avgörande för att undvika kostsamma konsekvenser. Det finns idag metoder för att hitta osakliga löneskillnader, men hur kan kostnaden att lösa löneskillnaderna estimeras? Hur kan kostnaden att göra en ojämställd lönestruktur jämställd uppskattas? Hur kan metoder för att stänga lönegapet förklaras för människor utan erfarenhet av matematiska resonemang? För att undersöka dessa frågor samlar studien empirisk data från litteratur, simulationer i Python ochen workshop. Simulation används för att analysera olika metoder för att stänga lönegapet mellan könen. En workshop kom att göras på SaaS-bolaget Pihr somär verksamma inom området. Resultaten föreslår ett flertal metoder att använda för att stänga lönegapet, med varierande kostnad och upplevd rättvisa. Det går aldrig att vara fullständigt säker om könsdiskriminering förekommer eller ej. Däremot är det möjligt att göra välgrundade estimeringar med hjälp av olika analysmetoder. Studiens resultat antyder också att metoder för att stänga lönegapet bör förklaras med ett informellt och icke-matematiskt språk, samt inkludera verklighetsbaserade exempel i en bekant kontext för mottagaren.
