The dramatic decline in the relative price of capital goods has been an important – but overlooked – driver of real investment. This column analyses cross-country price data to establish that deepening trade integration and productivity growth have both contributed to this decline. The erosion of support for international trade and sluggish productivity growth may limit further declines in relative prices of capital goods, which could negatively affect real investment rates.

Trade in intermediates (or ‘unbundling of production') and trade in capital have become increasingly important in last 25 years. This column shows that trade in intermediates generates a reallocation of capital across countries that exacerbates world inequality in both income and welfare. Unbundling of production hurts middle-income countries but helps those with high productivity. Trade in intermediates also increases within-country inequality, and this increase is U-shaped in the aggregate productivity level of the country.

According to the latest IMF projections, the global economy is now projected to grow at 3.3% in 2019, down from 3.6% in 2018. This is partly due to rising uncertainty in many parts of the world. This column shows how these statements are in line with the latest reading of the World Uncertainty Index, which shows a sharp increase in the first quarter of 2019. The increase in uncertainty observed in the first quarter could be enough to knock up to 0.5% of global growth over the course of the year.

Who will be the biggest loser in this trade war? Chad Bown tells Tim Phillips why it could be the WTO's dispute resolution system, and why we should worry if this happens.

In the late 1920s and early 1930s, Britain tried to reorient its trade towards the Empire via an advertising campaign led by the Empire Marketing Board. As this column shows, in economic terms, the initiative was a complete failure, producing no increase in the Empire’s share of Britain’s imports. Imperial sentiment conflicted with economic reality: Britain was the biggest global importer of produce from the late 19th century to the interwar period, and the EMB’s activities were constrained by entrenched consumer preferences for non-Empire foodstuffs, such as Argentine beef and Danish butter.

State borders can change due to both political and economic disputes. This column shows how the formation of the German state can be traced back to British political intervention at the end of the Napoleonic War. In preventing Russia from gaining territory westwards, Britain set in motion a series of events that gave Prussia strategic trade advantages. This led to the formation of Europe's first customs union (the Zollverein) and prepared the political unification of Germany.

Do trade and technology harm jobs? David Autor of MIT argues that we shouldn't mix the two as their effects are very different. Autor was giving the Economic Journal keynote lecture at the RES conference 2014.

Trade between the US and China is widely thought to have contributed significantly to the decline in US manufacturing employment between 1999 and 2007. Flipping the point of view, this column examines the impact on China of the growth in trade and finds that for every US manufacturing job lost, almost six new Chinese manufacturing jobs were created. International trade did not contribute to faster wage rises for Chinese industrial workers but instead channelled agricultural and non-participating workers into the industrial labour market.

The tide has turned in international trade, with watershed political moments across the world showing the growing popularity of protectionist measures. This column analyses the relationship between the distributional effects of trade and voting patterns by modelling a scenario in which NAFTA is dismantled. It finds that the areas that voted most overwhelmingly for the Trump administration are the same as those that would experience the greatest wage decreases if NAFTA were to be revoked, due to the strong correlation in areas that face import competition from and export exposure to NAFTA partners.

Countries are increasingly imposing new data policies which restrict both the domestic use of data and the flow of data across borders. This column uses an index of data policy restrictiveness for 64 major economies to demonstrate that restrictions that apply to the cross-border movement of data have an inhibiting effect on trade in services and, to a lesser extent, on the productivity of local companies and industries. Policies targeting the use of data, on the other hand, are found to have a comparably larger effect on productivity.

Foreign goods and workers are regularly blamed when the national economy is performing poorly. Economic theory suggests that trade and migration are substitutes – one can import cheaper products from a trade partner, or one can import the foreign workers themselves to narrow the difference in international factor prices. Yet, empirically this is not obvious. Based on available long-run data for international trade and migration since the late 19th century for the US and Canada, this column finds that during the interwar period, trade and immigration did in fact appear to be substitutes.

Recent years have seen dramatic progress in the predictive power of artificial intelligence in many areas, including speech recognition, but empirical evidence documenting its concrete economic effects is largely lacking. This column analyses the effect of the introduction of eBay Machine Translation on eBay’s international trade. The results show that it increased US exports on eBay to Spanish-speaking Latin American countries by 17.5%. By overriding trade-hindering language barriers, AI is already affecting productivity and trade and has significant potential to increase them further.

Economists often point out the benefits of trade, yet empirical evidence for these benefits has been hard to come by and tends to be recent. This column goes back to the first millennium BC to analyse the growth effects of one of the first major trade expansions in human history: the systematic crossing of the open sea in the Mediterranean by the Phoenicians. A strong positive relationship between connectedness and archaeological sites suggests a large role for geography and trade in development even at such an early juncture in history.

One of the largest refugee waves in recent history was that of the Vietnamese boat people. This column examines the long-run effect of the resettlement of Vietnamese refugees across the US on exports from the US to Vietnam. The first wave of refugees in 1975 was followed by a 20-year trade embargo on Vietnam. Following the lifting of sanctions, the share of US exports going to Vietnam was higher and more diversified in the states with larger Vietnamese populations. This evidence of the pro-trade effect of immigrants is a reminder that hosting refugees can represent an investment in the future.

Populist politicians argue that protectionism stimulates the domestic economy. This column uses data on temporary trade barriers from antidumping investigations to show that when small open economies have imposed protectionist measures, it has caused inflation to rise and real economic activity to fall. Empirical analysis and model-based exercises show that protectionism is costly even when used temporarily, even for economies stuck in liquidity traps, and regardless of the flexibility of the exchange rate.

The making and unmaking of trade agreements affects global production. This column reveals how deeper agreements have boosted countries’ participation in global value chains and helped them integrate in industries with higher levels of value added. Investment and competition now drive global value chain participation in North-South relationships, while removing traditional barriers remains important for South-South relationships.

Currency unions usually go hand in hand with deeper economic integration. But does that automatically mean more international trade? This column shows that since the end of WWII, currency unions have on average been associated with 40% more trade between member countries. The ‘thin’ relationships between countries who do not trade much with each other benefit the most from currency unions, with little in the way of a boost for more established trading relationships.

To date there has been little systematic evidence on the role of firms in explaining country performance. This column explores how the products of firms from all over the globe fare in competition in the US market. Results show that the countries that capture larger market shares have more exporters, producing higher-quality products, with a more dispersed distribution of firm attributes. Larger and richer markets are characterised by a more dispersed distribution of sales and quality, and a higher incidence of superstar firms.
