Abstract This contribution shows that a relevant curtailment of carbon emissions results from productivity-led working time reduction, i.e. increases in labour productivity converted into less working time. However, the interaction between working time reduction and GDP can constrain the achievement of emission reductions. To explore these interactions, we apply Eurogreen, a dynamic macro-simulation model, to France and compare three different scenarios: i. Working Time Reduction converts increases in labour productivity into more time affluence; ii. Global Working Time Reduction explores the effects on exports when working time reduction occurs also abroad; iii. Constrained Working Time Reduction additionally examines the impact of a binding fiscal rule. We find that the greater the performance in terms of emission reduction, the smaller the improvement in employment. Moreover, under working time reduction, changes in the sensitivity of wage to productivity growth affect the relationship between distribution and emission. The benefits in emissions reduction are still significant while the labour share increases with respect to the baseline.

以生产力为主导的工作时间减少对环境的影响

摘要 该贡献表明，碳排放的相关削减源于生产力主导的工作时间减少，即将劳动生产力的提高转化为更少的工作时间。然而，减少工作时间和 GDP 之间的相互作用会限制减排的实现。为了探索这些相互作用，我们将动态宏观模拟模型 Eurogreen 应用到法国并比较了三种不同的场景：减少工作时间将劳动生产率的提高转化为更多的时间富裕；ii. 全球减少工作时间探讨了在国外也发生工作时间减少时对出口的影响；三、受限工作时间减少还检查了具有约束力的财政规则的影响。我们发现，在减排方面的表现越大，就业改善越小。此外，在减少工作时间的情况下，工资对生产率增长的敏感性变化会影响分配和排放之间的关系。减排收益仍然显着，而劳动力份额相对于基线有所增加。
