A perennial and fundamental macroeconomic question is whether financial crises are negative demand or supply shocks. This column discusses how the response of international trade flows and prices to financial crises can shed light on the debate. Evidence based on a new dataset of two centuries of financial crises and trade suggests financial crises are clearly negative shocks to demand.

Successfully predicting which startups will thrive has long bedevilled economists. Using data from procurement auctions in Norway, this column finds that temporary demand shocks have long-term effects: startups that win a procurement auction are 20% larger than the runners-up, even years after the contract work has ended. In terms of job creation and sales growth, winning a procurement auction seems to have much larger effects for startups than for mature firms, which suggests the potential value in public policies that promote startups’ participation in government procurement auctions.

There is a lack of consensus on the importance of various drivers of long-run commodity prices. This column analyses a new dataset of prices and production for 15 commodities, including metals, agricultural goods, and soft commodities, between 1870 and 2015. Demand shocks due to rapid industrialisation and urbanisation have driven a substantial amount of variation in commodity price booms. While demand shocks have gained importance over time, commodity supply shocks have become less relevant.

Explanations for the Eurozone Crisis rely on the notion of cross-country asymmetries. The core-periphery pattern to the EU was first established by Bayoumi and Eichengreen in 1993, prior to the Eurozone. This column replicates their approach to explore whether the euro has strengthened or weakened this pattern. A new ‘coreness index’ indicates that the core-periphery pattern has weakened, and that a new, smaller periphery has emerged.

Today's monetary policy effectiveness depends on expectations of future monetary policy. Shocks affect such expectations, but the nature of the shock matters. This column presents evidence that negative demand shocks lead markets to expect looser policy in the short run. Negative supply shocks lead to expectations of looser policy in the medium to long run. Unexpected expansions – from either the supply or demand side – have no significant influence on markets' expectations of future monetary policy.

The recent dramatic fall in oil prices has renewed the interest in the importance of shocks in the oil price volatility. This column presents results from new research on the role of shocks and speculation on oil prices. The authors find that when speculation is short in duration, it has the weakest impact on oil prices and demand shocks have the largest. However, when speculation is allowed to have short- and long-term effects, it is the main contributor to the volatility of oil prices.

High US unemployment rates following the crisis are a primary policy concern, but are poorly explained by existing models. This column introduces a new model of frictional labour and product markets. Price rigidities yield testable predictions pointing to the source of unemployment and product market tightness. Evidence suggests that unemployment fluctuations are driven mostly by aggregate demand shocks.
