Corruption undermines the effectiveness of governments, slows economic development, and distorts democratic institutions. Muthukrishna et al. experimentally model the cost, causes, and cures for corruption, showing that anti-corruption strategies can occasionally backfire.

    The on-going European refugee crisis requires a concerted response across EU member states, including policy reform.

Comment and Opinion

    Basic income is a democratizing reform that is long overdue. A guarantee of basic security is necessary to allow people to stand as more independent. Other institutional adjustments are needed, but basic income will help other policies designed to support human development to be more effective.

    Many countries around the world have serious corruption problems at the expense of public welfare. An experimental economic study now identifies conditions that encourage leaders to accept bribes instead of sanctioning free-riders. Possible anti-corruption strategies can have positive effects, fail or even backfire.

    Effort is costly. People devalue personal rewards that require some measure of physical or even mental effort. Laboratory studies now suggest that physical effort is especially costly when engaged to benefit others. Even when people are willing, however, their efforts are often superficial, with people doing what is necessary but no more.

    Lockwood et al. use a real-effort task and computational modelling to examine how individuals choose to expend effort when rewards accrue to themselves versus others. They find that people are less motivated to work for others.
