Entry and trading in over-the-counter (OTC) derivatives markets have received considerable attention. However, many critical questions remain unaddressed. This column describes a formal study of banks’ incentives to enter and trade in OTC derivatives markets. In equilibrium, only large banks enter to become dealers, and middle-sized banks only enter as customers. Care should be given not to reduce rents so much when dealer participation costs are high.

The EU is about to extend economic partnership agreements signed in 2007 with countries of the Africa, Caribbean and Pacific region. Reflecting on the implementation difficulties associated with previous agreements and the minimal engagements in the upcoming ones, this column argues that these partnerships will fall short. No further integration of African economies will come out of them. Economic Partnership Agreements will have been a sideshow in the EU’s trade policy.

Using aggregate data can bias estimates of exchange rate pass-through by ignoring heterogeneity in price adjustment across sectors. This column uses micro-level price data to estimate pass-through for South Africa, using actual CPI weights to reflect changes in consumption bundles. The result is a micro-based estimate of pass-through with aggregation consistent enough to interest monetary policymakers.

The prevailing view of shadow banking is that it is all about regulatory arbitrage – evading capital requirements and exploiting ‘too big to fail’. This column focuses instead on the tradeoff between economic growth and financial stability. Shadow banking transforms risky, illiquid assets into securities that are – in good times, at least – treated like money. This alleviates the shortage of safe assets, thereby stimulating growth. However, this process builds up fragility, and can exacerbate the depth of the bust when the liquidity of shadow banking securities evaporates.

Online markets have unusual characteristics that allow testing whether the law of one price holds. This column uses a unique dataset to demonstrate that the frictions in the price adjustments in online markets are indeed lower. The authors find that in online markets the price change is smaller, the duration of price spell – shorter, the pass-through is larger, and speed of price adjustment – faster. In the future, we can expect smaller price differentials, bringing the law of one price closer to reality.
