Economists are often accused of focusing excessively on GDP, with the result that government policies make GDP a priority to the detriment of other contributors to well-being. This research proposes a broader summary statistic that incorporates consumption, leisure, mortality and inequality. While the new statistic is highly correlated with GDP per capita, cross-national deviations are often large: Western Europe looks considerably closer to the United States; emerging Asia has not caught up as much; and many developing countries are further behind. Each component of the statistic plays a significant role in explaining these differences, with mortality being the most important. While still imperfect, the statistic arguably provides better guidance for determining public priorities and evaluating policies than does GDP alone.
Big-box retail stores arriving from foreign countries have transformed the way Mexican households shop for goods, sparking a “supermarket revolution”. Traditionally, consumers in developing countries have shopped at street markets and small, independent stores. However, consumers have switched to shopping at foreign retailers, who offer a larger variety of products at cheaper prices. Despite concerns that foreign retailers might adversely affect local employment and household incomes, our evidence shows that allowing them to operate their businesses in Mexico has generated substantial welfare gains for households across the income spectrum by lowering the cost of living, while having limited impacts on total employment, incomes, and local businesses closing.
