Redistribution policies

  • Gross domestic product: Are other measures needed?

    GDP summarizes only one aspect of a country’s condition; other measures in addition to GDP would be valuable

    Gross domestic product (GDP) is the key indicator of the health of an economy and can be easily compared across countries. But it has limitations. GDP tells what is going on today, but does not inform about sustainability of growth. It does not measure happiness, so residents can be dissatisfied even when GDP is rising. GDP does not consider environmental factors or reflect what individuals do outside paid employment. It might increase in times of military conflicts and after natural disasters or terrorist acts, as the loss of property is not counted. Hence, complementary measures may help to show a more comprehensive picture of an economy.
  • Do payroll tax cuts boost formal jobs in developing countries?

    Payroll tax cuts in developing economies might be beneficial to the formal sector, even when the informal sector is large

    Carmen Pagés, March 2017
    Informal employment accounts for more than half of total employment in Latin America and the Caribbean, and an even higher percentage in Africa and South Asia. It is associated with lack of social insurance, low tax collection, and low productivity jobs. Lowering payroll taxes is a potential lever to increase formal employment and extend social insurance coverage among the labor force. However, the effects of tax cuts vary across countries, often resulting in large wage shifts but relatively small employment effects. Cutting payroll taxes requires levying other taxes to compensate for lost revenue, which may be difficult in developing economies.
  • Corporate income taxes and entrepreneurship

    The type, quality, and quantity of entrepreneurship are influenced significantly by corporate income taxes—though only slightly

    Jörn Block, May 2016
    Corporate income taxation influences the quantity and type of entrepreneurship, which in turn affects economic development. Empirical evidence shows that higher corporate income tax rates reduce business density and entrepreneurship entry rates and increase the capital size of new firms. The progressivity of tax rates increases entrepreneurship entry rates, whereas highly complex tax codes reduce them. Policymakers should understand the effects and underlying mechanisms that determine how corporate income taxation influences entrepreneurship in order to provide a favorable business environment.
  • Income inequality and social origins

    Promoting intergenerational mobility can make societies more egalitarian

    Lorenzo Cappellari, May 2016
    Income inequality has been rising in many countries. Is this bad? One way to decide is to look at the change in incomes across generations (intergenerational mobility) and, more generally, at the extent to which income differences among individuals are traceable to their social origins. Inequalities that reflect factors largely out of one’s control—such as local schools and communities—require attention in order to reduce income inequality. Evidence shows a negative association between income inequality and intergenerational mobility. The debate on whether community effects exert additional effects is still open.
  • The effects of minimum wages on youth employment and income

    Minimum wages reduce entry-level jobs, training, and lifetime income

    Policymakers often propose a minimum wage as a means of raising incomes and lifting workers out of poverty. However, improvements in some young workers’ incomes as a result of a minimum wage come at a cost to others. Minimum wages reduce employment opportunities for youths and create unemployment. Workers miss out on 
on-the-job training opportunities that would have been paid for by reduced wages upfront but would have resulted in higher wages later. Youths who cannot find jobs must be supported by their families or by the social welfare system. Delayed entry into the labor market reduces the lifetime income stream of young unskilled workers.
  • Do in-work benefits work for low-skilled workers?

    To boost the employment rate of the low-skilled trapped in inactivity is it sufficient to supplement their earnings?

    Bruno Van der Linden, March 2016
    High risk of poverty and low employment rates are widespread among low-skilled groups, especially in the case of some household compositions (e.g. single mothers). “Making-work-pay” policies have been advocated for and implemented to address these issues. They alleviate the above-mentioned problems without providing a disincentive to work. However, do they deliver on their promises? If they do reduce poverty and enhance employment, can we further determine their effects on indicators of well-being, such as mental health and life satisfaction, or on the acquisition of human capital?
  • Do skills matter for wage inequality?

    Policies to tackle wage inequality should focus on skills alongside reform of labor market institutions

    Stijn Broecke, February 2016
    Policymakers in many OECD countries are increasingly concerned about high and rising inequality. Much of the evidence (as far back as Adam Smith’s ) points to the importance of skills in tackling wage inequality. Yet a recent strand of the research argues that (cognitive) skills explain little of the cross-country differences in wage inequality. Does this challenge the received wisdom on the relationship between skills and wage inequality? No, because this recent research fails to account for the fact that the price of skill (and thus wage inequality) is determined to a large extent by the match of skill supply and demand.
  • Wage coordination in new and old EU member states

    Stronger wage coordination and higher union density are associated with lower unemployment and higher inflation

    Riccardo Rovelli, January 2016
    Aside from employment protection laws, which have been converging, other labor market institutions in new and old EU member states, such as wage bargaining coordination and labor union density, still differ considerably. These labor market institutions also differ among the new EU member states, with the Baltic countries being much more liberal than the others. Research that pools data on old and new EU member states shows that wage coordination mechanisms can improve a country’s macroeconomic performance. Stronger wage coordination and higher union density reduce the response of inflation to the business cycle.
  • Do minimum wages stimulate productivity and growth?

    Minimum wage increases fail to stimulate growth and can have a negative impact on vulnerable workers during recessions

    Joseph J. Sabia, December 2015
    Proponents of minimum wage increases have argued that such hikes can serve as an engine of economic growth and assist low-skilled individuals during downturns in the business cycle. However, a review of the literature provides little empirical support for these claims. Minimum wage increases redistribute gross domestic product away from lower-skilled industries and toward higher-skilled industries and are largely ineffective in assisting the poor during both peaks and troughs in the business cycle. Minimum wage-induced reductions in employment are found to be larger during economic recessions.
  • How are minimum wages set?

    Countries set minimum wages in different ways, and some countries set different wages for different groups of workers

    Richard Dickens, November 2015
    The minimum wage has never been as high on the political agenda as it is today, with politicians in Germany, the UK, the US, and other OECD countries calling for substantial increases in the rate. One reason for the rising interest is the growing consensus among economists and policymakers that minimum wages, set at the right level, may help low-paid workers without harming employment prospects. But how should countries set their minimum wage rate? The processes that countries use to set their minimum wage rate and structure differ greatly, as do the methods for adjusting it. The different approaches have merits and shortcomings.
