Evidence shows that individuals often do not act in a completely selfish manner, but rather take into account the welfare of other parties when making decisions. But how decision-makers trade off costs and benefits when the costs are dispersed among many individuals is unclear. This column discusses new experimental evidence showing that a large fraction of individuals are ‘insensitive to group size’, attaching similar weights to small and large groups. These findings provide a new explanation for a number of empirical patterns, including political and medical decision-making, lobbying, tax evasion, and charity donations.

Most countries with a generous pay-as-you-go social security system and ageing demographics will need to implement significant welfare reform, such as a major cut in benefits or a significant increase in distortionary taxation. Individuals’ uncertainty about when such a policy change will occur will cause precautionary saving and changes in factor prices, affecting aggregate welfare. This column uses evidence from Japan to show that delaying welfare reform will benefit the elderly, at a long-lasting cost to the young.

The bloody conflicts in Syria and Iraq have forced the issue of refugees onto the global agenda. However, among the neglected aspects of this discussion are how governance can be restored to conflict regions and the welfare effects that such actions, which are likely to be coercive, will have on local residents. This column examines the impact of a counter-insurgency programme in the Philippines on one development outcome in contested territories – malnutrition of young children. The programme saw a substantial long-term decrease in malnutrition in recaptured areas, but a rise in malnutrition in neighbouring areas. Such efforts may simply displace insurgents and their negative effects, rather than reducing them.

The goal of universal health coverage has been pursued by countries in a number of ways, most notably through demand-side policies. In 2005, Turkey extended basic healthcare services to its entire population under a free-of-charge, centrally administered system. This column examines the impact of this supply-side programme on mortality and birth rates. Results show that the program was successful in lowering both mortality and birth rates across provinces, particularly for the most vulnerable populations. These findings provide compelling evidence in favour of providing accessible healthcare services to all citizens.

The standard empirical evaluations of labour market policy only consider the direct effects of single programmes on their participants. This column argues that this fails to capture important aspects of real-world labour market policy – policy regimes and strategies. Using Swiss data, it employs a novel empirical approach that concurrently examines the effects of supportive and punitive policies (‘carrots’ and ‘sticks’). Policy regimes are shown to exert economically relevant effects, and accounting for these effects is crucial when designing labour market policy.

The international climate negotiations have moved away from targets such as keeping warming below 2°C in favour of more realistic goals. This column presents new evidence on the economic impacts of climate change. The initial impacts of climate change on welfare might be positive, but in the long run the negative effects dominate, and will be substantially higher in poor countries. Poverty reduction therefore complements greenhouse gas emissions reduction as a means to reduce the impacts of climate change.

The generosity of unemployment insurance is often cited as a reason for long spells of joblessness. But this view neglects other important, and potentially positive, economic aspects of such programmes. Using Austrian data, this column presents evidence that unemployment insurance has a positive effect on the quality of jobs that recipients find. This can in turn have a positive effect on future tax revenues, and has implications for the debate on optimal insurance generosity.

In Britain today, a majority of those in poverty live in working, rather than non-working, households. This challenges the long-held notion that paid work offers a route out of poverty. This column argues that structural changes in the labour market have brought about profound changes in the social security system. A failure to acknowledge these underlying changes means that dialogues about the political direction of the British economy can be problematic and potentially misleading.

Many low-income countries and development organisations are calling for greater liberalisation of labour immigration policies in high-income countries. At the same time, human rights organisations and migrant rights’ advocates demand more equal rights for migrant workers. This Vox Talk discusses the tensions between human rights and citizenship rights and argues that you cannot always have both.

Governments are now measuring happiness, or subjective wellbeing, and some have begun trying to maximise it. This column discusses recent research showing that happiness is not the same thing as utility. The choices people make suggest that they have desires and objectives other than happiness. It is therefore possible to make people worse off while increasing their reported subjective wellbeing.

Immigration continues to be a hotly debated topic in most OECD countries. Economic models emphasising the benefits of immigration for natives have typically neglected unemployment and redistribution – precisely the things voters are most concerned about. This column analyses the effects of immigration in a world with labour market rigidities and income redistribution. In two-thirds of the 20 countries analysed, both high-skilled and low-skilled natives would benefit from a small increase in immigration from current levels. The average welfare gains from immigration are 1.25% and 1.00% for high- and low-skilled natives, respectively.

Recent research has sought to quantify the magnitude of the welfare gains from trade. One of the main findings from this literature is that the gains from trade are relatively modest. This column suggests a channel that the standard approach typically abstracts from. It argues that trade induces changes in domestic productivity through a more efficient organisation of production within the supply chain.

US unemployment seems stuck at an unusually high level of 8%, prompting some to suggest a widespread skills mismatch. This column argues that a skills mismatch is not supported by the evidence. Rather, out of the possible explanations, it seems that any shift in the ratio between unemployment and vacancies is driven by either lower search efforts by the long-term unemployed or by a reduction in their employability.

The West perennially complains about China subsidising industry geared towards its domestic market. But what will happen when China enacts its latest Five Year Plan’s emphasis on domestic growth? This column argues that ending ‘pure-exporter subsidies’ – subsidies that boost Chinese exports while simultaneously protecting the least efficient, domestically oriented firms – will benefit Chinese consumers, but will cost the rest of the world.

Is religion a ‘crutch for the weak’? This column looks at data on religion and life satisfaction from across the globe and argues that it might just be insurance for the unhappy.

Should governments pay entitlements in cash or in kind to help reduce poverty? The authors of CEPR DP8581 find that cash transfers increase prices, especially in remote areas where the poorest consumers often live. In-kind transfers lower local prices, helping consumers at the expense of producers with a benefit equal to 11% of value of the transfer.

Public opinion is turning against migration during the recession, as generous European welfare states make migrants a potential fiscal burden. This column warns against the excessively exclusionary solutions to which voters are turning and suggests decoupling migration and the welfare state.

Crime rises when US welfare recipients run short of cash at the end of the month. This column discusses research that links the timing of financially-motivated crime and the timing of welfare payments. Cities that make monthly welfare payments see a clear monthly crime cycle, whereas cities that spread out the payments do not.

Since 1900, consumers have enjoyed a dramatic explosion in the number and quality of goods available. This column discusses a simple method for quantifying welfare gains from the introduction of new goods into the economy and their subsequent quality improvements using the personal computer as an example.
