The relationship between taxation and economic growth is complex, and relies in large part on the efficiency with which taxes are used. This column examines the impact of corruption on this relationship. The boost to welfare from reducing corruption is substantially larger than the marginal gains from optimising the tax rate for an existing level of government efficiency.

Government employee absenteeism is often a serious problem in developing countries. One potential reason is government positions being appointed as a kind of patronage to reward political loyalty. This column presents the results of an intervention designed to address government doctor absenteeism in Punjab, Pakistan. The programme provided government inspectors with a smartphone app to streamline information flows, and improved inspection rates. The results support the political patronage hypothesis and provide encouraging support for data-driven policymaking.

Open competition is regarded as a crucial ‘preventative tool’ that limits government discretion and abuse of power when awarding procurement contracts. However, various studies have identified numerous drawbacks to using open auctions when contracting is imperfect. This column discusses the effects of increased buyer discretion on public procurement in Italy. Increased discretion raises the number of repeated wins by contractors, suggesting long-term relationships between buyers and sellers. Furthermore, productive buyer-seller relationships appear to outnumber corrupt ones.

Ethnic favouritism is widely regarded as an African phenomenon, or at most a problem of poor and weakly institutionalised countries. This column uses data on night-time light intensity to challenge these preconceptions. Ethnic favouritism is found to be as prevalent outside of Africa as it is within, and not restricted to poor or autocratic nations either. Rather, re-election concerns appear to be an important driver of the practice.

In addition to the traditional mass media, social media has become a channel through which citizens can hold public officials and corporate leaders to account. But social media commentators can be vulnerable to manipulation and reputational damage. This column uses data on a popular blogger in Russia to show that blogs are critical of corruption in state-controlled companies can lead to decreased profit diversion and corruption by the targeted companies. Social media appears to play an important role in improving accountability, particularly when traditional media is censored or political competition is limited.

Politicians may have the opportunity to interfere with the allocation of public services to help to achieve their electoral objectives. This column argues that politicians share rents with central players to build and sustain coalitions. Using detailed data from the Philippines, it examines social networks and the allocation of municipal services. Households with greater potential to broker political coalitions do indeed appear to receive more services from their municipal government.

Spain enjoyed substantial growth in the decade prior to the Global Crisis, despite declining aggregate productivity. Recent research blames the poor productivity on different forms of a ‘financial resource curse’. This column argues that resource misallocation was particularly severe due to corruption and crony capitalism. This suggests future growth will require serious political reforms.

Institutional redesign and reform are currently being debated and implemented at the EU and EZ levels. However, there is a growing institutional gap across member countries – especially between the core and periphery. This column illustrates the extent of this gap. Weak institutions have already stifled reform efforts, such as the Economic Adjustment Programs undertaken by Greece and Portugal. The success of pan-European reforms and the future of the Eurozone will require coordinated action to close this institutional gap.

India is electing more and more politicians that are, or have been, accused of criminal activity. This column asks whether accused – and potentially corrupt – politicians influence economic activity by focusing on data from road construction, which is often tied to corruption. The evidence tentatively suggests that caste-based and patronage politics favours lower quality politicians, who in turn deliver benefits to specific groups. This generally leads to lower aggregate growth.

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.
