In Japan, loans with 100% guarantees account for more than half of all loans covered by public credit guarantee schemes, but banks claim that they do not offer loans without sufficient screening and monitoring even if the loans are guaranteed. This column presents evidence of adverse selection and moral hazard in Japanese credit guarantee schemes. The problem is less severe for loans with 80% guarantees.

Individuals who work in the finance sector enjoy a significant wage advantage. This column considers three explanations: rent sharing, skill intensity, and task-biased technological change. The UK evidence suggests that rent sharing is the key. The rising premium could then be due to changes in regulation and the increasing complexity of financial products creating more asymmetric information.

The Global Crisis has intensified debates over the merits of financial innovation and the optimal size of the financial sector. This column presents a model in which the growth of finance is driven by the development of a financial innovation. The model can help explain the securitised mortgage debacle that triggered the latest crisis, the tech bubble in the late 1990s, and junk bonds in the 1980s. A striking implication of the model is that regulation should be toughest when finance seems most robust and when innovations are waxing strongly.

Many drugs sold in poor countries are counterfeit or substandard, endangering patients’ health and fostering drug resistance. Since drug quality is difficult to observe, pharmacies in weakly regulated markets may have little incentive to improve quality. However, larger markets allow firms to reorganise production and invest in technologies that reduce the marginal cost of quality. This column discusses how the entry of a new pharmacy chain in India led incumbents to both cut prices and raise drug quality.

All firms need capital. Much research addresses the choice between issuing various types of securities – for example, between issuing debt and equity. However, another method of financing has received relatively little attention – selling non-core assets, such as property, divisions, or financial investments. This article explains the conditions under which an asset sale is the preferred means of raising capital, and highlights how a manager should go about deciding between selling assets and issuing securities.

Mortgage markets arguably spawned the post-Lehman crises – think subprime, Ireland, and Spain. This column argues that asymmetric information between competing lenders is an important feature in the financing of newly developed homes. Interestingly, lenders differ significantly in their information about true underlying housing collateral values. It is the identification of asymmetric information that allows policymakers to develop proposals that would improve how the market works and, with the right policies, how governments can limit the negative impact of asymmetry.

With governments strapped for cash, charities are stepping up to provide public goods. But how can charities mobilise support from small donors to fund their work? CEPR DP8922 investigates whether altruists would donate more if they knew more about a charity’s quality. In the authors’ experiment, Bill and Melinda Gates matched donations to a particular charity. Small donors saw this as a signal of the charity’s quality – and donations soared.

How does economic theory need to adjust in light of the global financial crisis? This column presents a new insight on how innovation leads to rent capture, which in turn is a sign of a potential crisis. This stems from asymmetric information in the financial sector. To avoid a repeat of the crisis, policymakers need to increase transparency.

This column studies the online (illegal) market for male sex work. It shows that participants find ways to get the prices right, even in the absence of formal enforcement mechanisms, using technology to share and disseminate information. The risk of fraud is disciplined by client reviews and demand for photos in escorts’ advertisements.

The labour market suffers from asymmetric information, coordination, and collective action failures. This column explains how labour market intermediaries, such as online job boards and centralised job-matching institutions, work to improve labour market outcomes. These intermediaries will perform important coordinating functions even as information costs fall.

The current crisis is a modern form of a traditional banking crisis. The 125-year-old Bagehot's doctrine tells us how governments should react – lend to solvent but illiquid financial institutions. While easy to state, the doctrine is hard to apply. The key question to assess the future consequences of current central bank policy is whether the subprime mortgage crisis arises in the context of a moderate or a severe underlying moral hazard problem.
