This paper argues that existing large-scale software developer surveys are inadequate for measuring the relative importance of these three factors. Moreover, previous econometric studies that collect their own unique datasets generally measure the importance of only one supply factor in isolation. To fill the gap, I specify a dynamic programming model of joint labour supply and open-source contribution decisions that can provide empirical estimates of relative importance within a single unified framework.","PeriodicalId":261871,"journal":{"name":"IZA: General Labor Economics (Topic)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126149977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Third, we explore whether using weighting schemes from the machine learning literature improves the average forecast. Compared to equal weights the effect of the weighting scheme on forecast accuracy is small in our application.","PeriodicalId":261871,"journal":{"name":"IZA: General Labor Economics (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115799699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This issue is investigated using a discrete choice static labour supply model for married couples in Ireland. The model incorporates fixed costs of working and simultaneously explains participation decisions and preferred hours of work. Details of the tax system are fully incorporated, and key elements of the welfare system are also taken into account. The model is estimated using data from the 1994 wave of the Living in Ireland Survey. The results are used to analyse the labour supply effects of a move to greater independence in the tax treatment of couples. The influence of tax structure on participation is reconsidered in the light of trends in women’s participation in the labour market and two key changes in the structure of taxation: a shift from a joint or aggregated basis of assessment to an “incomesplitting” system in 1980 and a further substantial shift from income-splitting towards greater independence from 2000 onwards.","PeriodicalId":261871,"journal":{"name":"IZA: General Labor Economics (Topic)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124084353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because it is hard to separate effort, ability and output in many real workplace settings, the empirical evidence on the incentive effect of tournaments is thin. There is even less evidence on the impact of sabotage because real world acts of sabotage are often subtle manifestations of subjective peer evaluation or \"office politics.\" We discuss a real effort experiment in which effort, quality adjusted output and office politics are compared under piece rates and tournaments. Our results suggest that tournaments increase effort only in the absence of office politics. Competitors are more likely to sabotage each other in tournaments and, as a result, workers actually provide less effort simply because they expect to be the victims of sabotage. Adjusting output for quality with the rating of an independent auditor shrinks the incentive effect of the tournament even further since output tends to become more slipshod.","PeriodicalId":261871,"journal":{"name":"IZA: General Labor Economics (Topic)","volume":"227 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114347238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More than 60% of migrants from the guestworker countries are indeed repeat or circular migrants. Migrants from European Union member countries, those not owning a dwelling in Germany, the younger and the older (excluding the middle ages), are significantly more likely to engage in repeat migration and to stay out for longer. Males and those migrants with German passports exit more frequently, while those with higher education exit less; there are no differences with time spent out. Migrants with family in the home country remain out longer, and those closely attached to the labor market remain less; they are not leaving the country more frequently.","PeriodicalId":261871,"journal":{"name":"IZA: General Labor Economics (Topic)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130811891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A revenue-neutral increase in both the wage tax and tax exemption and a revenue-neutral change in the composition of labour taxation towards the tax with the smaller tax base will lead to the same results: they moderate wages, workers’ effort, effective labour input and aggregate output. Whether employment rises or falls, however, depends in both reforms on the magnitude of the pre-reform total tax wedge. The larger this tax wedge is, the more negative is the impact of reforms on workers’ effort. A larger total tax wedge increases the negative effect of tax progression on labour productivity and thus thwarts the positive employment effect of wage moderation.","PeriodicalId":261871,"journal":{"name":"IZA: General Labor Economics (Topic)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126595951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three generations who completed education during the period from pre-1949 to the beginning of the 2000s are included. The focus is on the influence of family class status (chengfen) on offspring education. Our investigation suggests that family class status is still important for the intergenerational transmission of education. The offspring of landlord/rich peasant families are more likely to achieve higher educational attainment, even though parental education, family wealth, and other family characteristics are the same. The unique determinant of the intergenerational transmission of education in the postreform era is found to be an education-oriented family culture, created as an intergenerational cultural rebound against class-based social discrimination during the Maoist era. We have also found that the cultural reaction is a combination of class-specific effects with cohort-specific effects.","PeriodicalId":261871,"journal":{"name":"IZA: General Labor Economics (Topic)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117190921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
