Large exchange rate swings remain a prominent and recurring feature of the world economy. This column uses household consumption patterns to examine the distributional impact of the devaluation of the peso during Mexico’s ‘Tequila Crisis’. Cost of living increases are found to be 1.25 to 1.6 times higher for the poor compared to the rich. In the interests of equity, exchange rate policy should take account of such distributional impacts.

Fracking has driven an oil and natural gas boom in the US over the past decade. This column examines the impact these mining activities have had on local and regional economies. US counties enjoy significant economic benefits, including increased wages and new job creation. These effects grow as the geographic radius is extended to include neighbouring areas in the region. The results suggest that the fracking boom provided some insulation for these areas during the Great Recession, and lowered national unemployment by as much as 0.5%.

Economists have traditionally viewed healthcare as a luxury good – consumption of it will increase more than proportionally as income rises. This column challenges this view, exploiting the windfall of lottery winnings to estimate elasticities for healthcare demand in the UK. Results suggest that income elasticities for public healthcare services are close to zero. A medium to large windfall is found instead to increase the uptake of private health insurance and preventative services. This suggests that rising incomes will increase private sector demand, but will leave public healthcare demand unchanged.

Many policy design issues depend crucially on the nature of the idiosyncratic risks to labour income. The earning dynamics literature has typically relied on an implicit or explicit assumption that earnings shocks are log-normally distributed. This column challenges conventional knowledge by bringing in new evidence from a very large administrative dataset on US workers. It presents evidence suggesting income shocks exhibit substantial deviations from log-normality, and that shock persistence depends on income levels as well as the size and sign of the shock.

Inequality – long ignored – is now centre stage in debate about economic policy around the globe. This column introduces the Chartbook of Economic Inequality, a summary of long-run changes in economic inequality for 25 countries over more than 100 years.

Why some countries are richer than others is among the most difficult and important questions in economics. Yet, the Penn World Table, widely used to compare living standards across countries, has faced criticism in recent years. This column discusses how the new version of the tables both addresses these criticisms and provides a wider range of tools that will help researchers gain insight into why income differs across countries.

What distributional effect do natural-resource booms have on wealth, income and economic power? Using Australia as a case study, this column argues that resource booms tend to exacerbate inequality. The distributional impact of commodity-price shocks in Australia yield important lessons for primary producers from the developmental south, and it’s important for resource-rich developing countries to design appropriate policies to tackle this inequality.

Cross-country inequality is persistent. This column draws on economic history to explain the mechanisms by which dramatic cross-country differences in income emerge. We can reduce inequality through policies that facilitate the penetration of new technologies in poor and middle-income countries. Such policies can go a long way towards reducing existing cross-country income disparities.

Average income per capita is strongly correlated with more schooling, but this relationship is more complex than it appears. This column presents new research showing that a large part of the correlation is attributed to the causal effect of economic prosperity on the formation of human capital via schooling.

Many of the emerging economies of the last two decades are now ensnared by ‘the middle-income trap’, in which middle-income countries don’t quite push through to high income status. This column presents recent research suggesting that, if governments act early and decisively to improve access to advanced infrastructure, enhance the protection of property rights, and reform labour markets, trapped economies – like their East Asian counterparts in the 1990s – can push on through.

How does consumption respond to a change in income – whether expected or unexpected, temporary or permanent? This column reviews evidence from diverse sources and suggests that if financial market arrangements and liquidity constraints are binding, even changes in income that are predictable can have a significant effect on consumption. This supports the idea that tax changes can have a considerable impact on expenditure.

Andrew Clark of the Paris School of Economics talks to Romesh Vaitilingam about his research on the relationship between income and health, which examines changes in the health and health behaviours (smoking and drinking) of British people who win prizes in the national lottery. The interview was recorded at the Royal Economic Society’s annual conference at the University of Surrey in March 2010.

Everyone knows that educated people earn more, smoke less, are less likely to be obese and live longer. This column discusses recent research that shows more educated parents also spend more time with their kids – a result ripe with implications for the inter-generational persistence of income and health inequalities.

Why are some societies democratic, others not? Why do some societies develop modern effective nation states, while others do not? Why do some societies experience revolutions, while others undertake more gradual change? And finally, why are some relatively prosperous, while others are not?
