The new European copyright directive prohibits online aggregators from linking to news outlets or publications without the prior authorisation of the publisher. This column uses the 2014 shutdown of Google News in Spain to demonstrate that news aggregators can have a positive impact on outlets’ traffic, in particular outlets with more casual readers, those with a low national rank, and those with fewer international visitors. This heterogenous effect suggests publishers and aggregators may wish to negotiate their own specific compensation terms for content use.

Media platforms traditionally delivered the widest possible audience to advertisers. This column argues that the arrival of digital competition in media has created a battle for ‘exclusive eyeballs’ – a niche audience not shared with competitors. While this increases diversity in the media, it also incentivises media outlets to polarise to attract specific groups, and to create echo chambers to retain them.

A general challenge facing competition authorities in the digital era is learning how to apply the traditional tools of competition policy in multi-sided platform environments. This column argues that the Google Android case offers a great example of the need to consider the implications of the market's two-sidedness. It also argues that bundling can, in fact, be profitable by virtue of its effect on competition once one accounts for some of the key features of mobile app markets.

The European Commission’s case against Android has been hailed as a “milestone” in antitrust enforcement. This column, written by Google’s Chief Economist, argues that the case is more of a millstone than a milestone for not just Google, but the entire Android ecosystem of equipment manufacturers, carriers, app developers, and end users.

The European Commission’s decision to fine Google €4.34 billion for abuse of market power has been accused of being politically motivated and of risking higher prices for consumers. This column argues that the Commission’s decision has economic merit and falls within established legal precedent. As mobile search is the key gateway to access information, we should be concerned about dominance in this market for its potential distortionary effects on innovation and consumer outcomes across multiple other markets.

The Internet has opened up a whole new realm in advertising, with Google at the helm. Within this, search advertising has recently come under investigation from competition authorities. This column seeks to aid the understanding of this special market, its definition, its structure, and the role of its leader.

For how long have we cared about poverty? Tracing the number of references to the word “poverty” in books published since 1700, this column shows that there was marked increase between 1740 and 1790, culminating in a “Poverty Enlightenment”. Attention then faded through the 19th and 20th centuries, leaving room for the second Poverty Enlightenment in 1960 – and interest in poverty still rising.

The dominant firm in online advertising is under investigation by many antitrust authorities. The EU Competition Commission is the latest to breathe heavily down its neck. Analysing Google’s market behaviour, particularly its search and display advertising model, this column argues that such investigations are welcome; the world needs to know if Google is abusing its market power.

Many countries in Europe now have a coalition government. This column uses data from Italy to argue that this comes at a cost. It finds a positive and significant relationship between the political instability caused and a rise in government yields, making today’s fiscal adjustments even more difficult and painful.

Is concern for the environment a luxury good? This column presents data from Google searches for the words “unemployment” and “global warming” by US users. It argues that recessions increase concerns about unemployment at the expense of people’s interest in climate change – in some cases leading them to deny its existence.
