Individuals are never fully certain whether economic developments are persistent or temporary. This column shows that this permanent-transitory confusion has pervasive implications. It argues that the confusion injects the past into even purely forward-looking New-Keynesian frameworks, and shows empirically that inflationary forecasts indeed rely on past inflation.

Policy advice for countries managing oil and gas windfalls is typically to smooth consumption boosts by borrowing on international capital markets pre-windfall, repaying the debt and accumulating assets in a sovereign wealth fund during the windfall, and withdrawing from that fund when the windfall ends. This column outlines various reasons why this approach can be disastrous for developing countries, and also considers the best response to a commodity price crash.

Japan’s prime minister recently announced that a planned 2% VAT increase would be postponed from 2017 to 2019. This column explores how Japanese household consumption adjusted to a VAT increase that was announced in 2013 and implemented in 2014. Household consumption fell by around 4% upon announcement and 1% upon implementation, suggesting that most of the negative impact of a VAT rate increase occurs at the time of the announcement.
