Central bank independence was supposed to end politically driven monetary policy. This column discusses new evidence showing a sizeable spike in the growth rate of cash and overnight bank deposits centred on election days. The spike is present in countries with weak political institutions, but not in OECD countries. The cycle seems to be related to the cash demand created by systemic vote buying.

As numerous Greek MEPs opposed the Eurozone summit deal, implementation will require a broad coalition of political parties. This column argues that corruption in Greek politics will prevent the formation of such a coalition. The heavy debt service leads parties to invent extreme ways of responding to super-austerity and to strongly oppose direct reforms that challenge existing clientelism. The way out is to sign a new agreement that combines debt restructuring and radical transparency reforms, including naming-and-shaming practices, to block clientelism in the medium and long run.

The evidence about the effect of bribery on economic growth is mixed. Some find it harmful while others believe it helps via a ‘grease the wheels’ effect. This column argues that the ambiguity can be explained by divergent effects of the mean and dispersion of corruption. A high bribery-mean retards productivity growth of firms, but a high bribery-dispersion facilitates performance of weak firms.

The 2014 FIFA World Cup is upon us. This column argues that there will be plenty of partying, but also plenty of protests fuelled by the gross mismanagement and limited economic benefits from hosting the Cup. Stadia may be ready, but much planned infrastructure has already been abandoned. Indeed, rent-seeking may be one reason nations bid for the Cup. Since the returns to transportation infrastructure are higher in poor countries, the international community should work to stamp out corruption so that poor countries can continue to host mega-events like the World Cup.

Eliminating corruption is a central policy goal of policymakers around the globe. It is known that corruption is a barrier to economic development because it increases the costs and risk of business activity, and deters investment. This column discusses a new study analysing the opposite causal relationship – the effect of economic growth on corruption. Both theoretical and empirical evidence show that economic growth causes the amount of corruption to fall.

Based on statistical measures of different degrees of democracy vs. autocracy, this article briefly reviews the progress of democracy around the world during the past 212 years, and places democratic developments in Africa since 1960 in that context. Democracy is positively associated with education, which in turn is associated with lower fertility and greater longevity. Democracy is also associated with reduced corruption. Together, these effects suggest democracy should be good for growth – a hypothesis that is borne out by the data.

Do higher government wages reduce corruption? This column argues that they do, but only in relatively poor countries. When a country’s poor, higher government wages reduce bureaucrats’ incentive to extract illegal incomes. However, as income per capita rises, higher government wages gradually lose their effectiveness in combating corruption.

Russian involvement in Cyprus was widely recognised during the acute phase of the most recent EZ crisis. This column argues that some of this is driven by corruption-linked money laundering. Using official Russian statistics, the authors estimate a standard model of FDI location to identify usual patterns related to nations with lax anti-money laundering measures such as Cyprus and the British Virgin Islands. Funds from such nations were biased towards locating investments in the most corrupt Russian regions compared to a group of genuine foreign investors.

Public spending on large-scale projects is often a way of sneaking in protectionism through the back door and there are many cases of outright corruption. With the EU and US pushing hard for more open public procurement elsewhere in the world, this column asks just how open these markets are, particularly in the EU, which claims to have the most open market in the world.

Despite best intentions, government policies can sometimes provide politicians and others with an incentive to break the law. This column analyses the link between state support for renewable energy and corruption. It provides some evidence of this connection for the case of the tradable green certificate system, a policy introduced in Italy in 1999 to promote wind power.

For democratic theorists, the notion that greater transparency improves accountability is axiomatic: when voters find out about political corruption, they punish the offending politicians by not voting for them again. But, the authors of CEPR DP8790 argue, many voters also respond to evidence of corruption by not voting at all – indicating that more transparency might not automatically result in a healthier democratic process.

Recent innovations in methodology have sparked a remarkable expansion in economists’ ability to measure corruption. This column reviews these new techniques, which range from inferring corrupt links from stock prices to attempting to observe bribes undercover. It concludes that, while corruption is prevalent in poor countries, there remains little consensus about its magnitude or the best way to fight it.

Did anti-regulation lobbying fuel the subprime crisis? This column shows that there is a strong relationship between financial industry lobbying and favourable financial regulation legislation. It argues that the financial industry fought, and defeated, measures that might have curbed some of the reckless lending practices that many think played a pivotal role in igniting the crisis.

In the debate over the pros and cons of government spending, the efficacy of public investment is a point on which many conclusions hinge. This column introduces a new Public Investment Management Index that benchmarks the quality and efficiency of the investment process across 71 developing and emerging countries.

The natural-resource curse is now a staple in the development economist’s diet. Natural resources have tended to lead to lower economic growth, except in democratic countries or those with robust institutions. This column presents a political economy model to explain this phenomenon, focusing on the threat of revolutions.

For centuries, Europe was ruled by empires wielding global influence. This column shows that these empires can leave behind a long-lasting legacy through cultural norms. Comparing individuals on opposite sides of the long-gone Habsburg Empire border within five countries, it shows that firms and people living in what used to be the empire have higher trust in courts and police.

Cash crops provide the livelihoods for millions of people in sub-Saharan Africa. This CEPR/World Bank book explores the effects of increasing competition in these markets. It finds that while competition improves welfare for farmers on the whole, policymakers should still consider the potential winners and losers in each case.

Millions of people in sub-Saharan Africa rely on cash crops for their livelihoods . This column presents a new CEPR/World Bank book exploring the effects of increasing competition in these markets. It finds that while competition improves welfare for farmers on the whole, policymakers should still consider the potential winners and losers in each case.

Does corruption sand or grease the wheels of economic growth? This column reviews recent research that uses meta-analysis techniques to try to provide more concrete answers to this old-age question. From a unique, comprehensive data base of 460 estimates of the impact of corruption on growth from 41 studies, the main conclusion that emerges is that there is little support for the “greasing the wheels” hypothesis.

Performance-based aid provides a promising alternative to the failed traditional approach but hardly any empirical evidence exists on its effectiveness in inducing reforms. This column provides new evidence from the Millennium Challenge Corporation’s impact on corruption. It suggests performance-based aid can lead to reforms but only if uncertainty about the timeliness and amount of aid rewards is avoided.
