Whether incumbent firms deter new entrants in a more concentrated market has been of major concern to antitrust authorities. This column introduces empirical evidence on the relationship between market concentration and entry in the intermediate goods market, using unique data from the Japanese auto market. The findings show a U-shaped relationship, whereby entry decreases and then increases as the market concentrates.

Economists have been exploring the relationship between prosperity and trust since the 1950s. This column explores the possible relationships, arguing that enhanced economic prosperity acts as a signal that fellow citizens are trustworthy. The more optimistic assessment then breeds trust among individual citizens. This theory suggests the possibility of a mutual feedback between trust and economic growth.

Informality is widespread in most developing countries. A challenge for governments is to lure informal firms into the formal economy. This column presents evidence from an experiment designed to induce formalisation in Colombia. Assistance through the bureaucratic process and the removal of the fixed costs of formalising increased the likelihood of formalisation. However, this effect did not persist over time, with many firms returning to the informal sector when minimal fixed costs came back into effect.

Theories of voluntary disclosure suggest that even when disclosure is voluntary, market forces can drive firms to completely reveal information about their quality. This column investigates these predictions in an experimental setting. Laboratory results suggest widespread failures of the theoretical predictions – senders do not fully disclose, and receivers are not fully sceptical about non-disclosure. This suggests a role for policymakers to help customers understand the sound of silence.

A minor adverse shock to financial markets can be propagated by liquidity strains, leading to a major crisis. This column suggests a novel measure to address systemic liquidity risk – a Macroprudential Liquidity Buffer, which would require financial institutions to hold systemically liquid assets in proportion to their liabilities less regulatory capital. This proportion varies positively with growth in system-wide funding needs, so the liquidity buffer increases when non-equity funding is growing.
