Donald Trump has consistently made headlines with unusual and potentially dangerous economic policy proposals, including threatening to pull out of the WTO, renegotiating trade agreements, and imposing tariffs on imports from Mexico and China. This column explores the legal and economic dimensions of these proposals. Old and modern legal statutes could allow a US president to implement such policies, and the repercussions for the US economy could be severely negative.

Working with the wrong accounting classifications can lead to wrong conclusions in any area of economics. But it is especially treacherous in international finance, due to the importance of key currencies and the operations of multinational firms, especially global banks. Much of the analysis in international finance is still conducted under the assumption that the GDP area, decision-making unit and the currency area coincide – the so-called ‘triple coincidence’. This column illustrates the common analytical missteps that can arise by reviewing three examples from the recent past, and argues that a proper analysis of capital flows necessitates paying greater attention to basic accounting building blocks.

The objective of financial stability policy is unclear. Is it the resilience of the financial system, avoiding the costs of systemic collapse, or managing the credit cycle, containing the costs of resource misallocation and over-indebtedness? This column argues that the answers have serious implications for what can decently be delegated to independent ‘macroprudential authorities’, but have barely been debated in those terms.

Covered interest parity is close to a physical law in international finance, yet it has been consistently violated since the Global Crisis. Violations since 2014, once banks had strengthened their balance sheets and regained easy access to funding, are especially puzzling. This column argues that the violation reflects a combination of foreign exchange hedging demand and tighter limits to arbitrage. Hedging demand has been boosted, in particular, by divergent monetary policies in an ultra-low interest rate environment, while tighter limits to arbitrage result from a stricter management of banks’ balance sheets.

This column presents data from 18 advanced economies that reveal large differences in the potential upside of reform depending on the sector in which a firm operates, its size, and its financial health.
