This paper describes financial systemic risk as a pollution issue. Free riding leads to excess risk production. This problem may be solved, at least partially, either by financial regulation or by taxation. From a normative viewpoint, taxation is superior in many respects. However, reality shows that financial regulation is adopted more frequently. This paper makes a positive, politico-economic argument. If the majority chooses regulation, the level is likely to be too harsh. If it chooses taxation, then the level is likely to be too low. Due to regressive effects, a tax on financial transactions receives low support from a majority of low polluting portfolio owners. The same kind of majority may strategically choose regulation in order to burden the minority with a larger share of the cost of reducing systemic risk

We assess the procyclical effects of bank capital regulation in a dynamic equilibrium model of relationship lending in which banks are unable to access the equity markets every period. Banks anticipate that shocks to their earnings as well as the cyclical position of the economy can impair their capacity to lend in the future and, as a precaution, hold capital buffers. We find that under cyclically-varying risk-based capital requirements (e.g. Basel II) banks hold larger buffers in expansions than in recessions. Yet, these buffers are insufficient to prevent a significant contraction in the supply of credit at the arrival of a recession. We show that cyclical adjustments in the confidence level underlying Basel II can reduce its procyclical effects on the supply of credit without compromising banks’ long-run solvency targets

We identify the impact of intermediate goods markets imperfections on productivity downstream. Our empirical specification is based on a model of multifactor productivity (MFP) growth in which the effects of upstream competition can vary with distance to frontier. This model is estimated on a panel of fifteen OECD countries and twenty industries over 1985 to 2007. Competitive pressures are proxied with industry product market regulation data. We find evidence that anticompetitive upstream regulations have significantly curbed MFP growth over the past fifteen years, and more strongly so for observations that are close to the productivity frontier

We examine the effect of say on pay regulation in the UK. Consistent with the view that shareholders regard say on pay as a value-creating mechanism, the regulation’s announcement triggered a positive stock price reaction at firms with weak penalties for poor performance. UK firms responded to negative say on pay voting outcomes by removing controversial CEO pay practices criticized as rewards for failure (e.g., generous severance contracts) and increasing the sensitivity of pay to poor realizations of performance

Existing studies suggest that systemic crises may arise because banks either hold correlated assets, or are connected by interbank lending. This paper shows that common regulation is also a conduit for interbank contagion. One bank's failure may undermine confidence in the banking regulator's competence, and, hence, in other banks chartered by the same regulator. As a result, depositors withdraw funds from otherwise unconnected banks. The optimal regulatory response to this behavior can be privately to exhibit forbearance to a failing bank. We show that regulatory transparency improves confidence ex ante but impedes regulators' ability to stem panics ex post

This study examines the impact of disclosure requirements on the resolution costs of failed banks. Consistent with the hypothesis that disclosure requirements mitigate information asymmetries in the auctions for failed banks, I find that, when failed banks are subject to more comprehensive disclosure requirements, regulators incur lower costs of closing a bank and retain a lower portion of the failed bank's assets, while bidders that are geographically more distant are more likely to participate in the bidding for the failed bank. The paper provides new insights into the relation between disclosure and the reorganization of a banking system when the regulators' preferred plan of action is to promote the acquisition of undercapitalized banks by healthy ones. The results suggest that disclosure regulation policy influences the cost of resolution of a bank and, as a result, could be an important factor in the definition of the optimal resolution strategy during a banking crisis event

Using a 2004 Chinese securities regulation that requires equity offering proposals to obtain the separate approval of voting minority shareholders, we examine whether giving minority shareholders increased control over corporate decisions helps to reduce value-decreasing corporate decisions for firms domiciled in weak investor protection countries. We find that the regulation deters management from submitting value-decreasing equity offering proposals in firms with higher mutual fund ownership. There is also weak evidence that minority shareholders are more likely to veto value-decreasing equity offering proposals in firms with higher mutual fund ownership in the post-regulation period. Overall, our evidence suggests that in weak investor protection countries, the effect of granting minority shareholders increased control over corporate decisions on the quality of corporate decisions depends on the composition of minority shareholders

Calls for benefit-cost analysis in rule-making, based on the Dodd-Frank Wall Street Reform Act, have revealed a paucity of work on allocative efficiency in financial markets. We propose three principles to help fill this gap. First, we highlight the need for quantifying the statistical cost of a crisis to trade off the risk of a crisis against loss of growth during good times. Second, we propose a framework quantifying the social value of price discovery, and highlighting which arbitrages are over- and under-supplied from a social perspective. Finally, we distinguish between insurance benefits and gambling-facilitation harms of market completion.

In many regulated markets, private, third-party auditors are chosen and paid by the firms that they audit, potentially creating a conflict of interest. This article reports on a two-year field experiment in the Indian state of Gujarat that sought to curb such a conflict by altering the market structure for environmental audits of industrial plants to incentivize accurate reporting. There are three main results. First, the status quo system was largely corrupted, with auditors systematically reporting plant emissions just below the standard, although true emissions were typically higher. Second, the treatment caused auditors to report more truthfully and very significantly lowered the fraction of plants that were falsely reported as compliant with pollution standards. Third, treatment plants, in turn, reduced their pollution emissions. The results suggest reformed incentives for third-party auditors can improve their reporting and make regulation more effective

A long line of research investigates whether the retail prices of electricity and natural gas send proper signals about scarcity in order to induce efficient consumption. Historically, regulated utilities have not designed tariffs that set marginal prices equal to marginal costs. Currently, some jurisdictions are opening the retail sectors to competition via “retail choice.” These new regimes replace imperfect regulation with imperfect competition as the process by which retail tariffs are formed. We discuss the challenges in evaluating the efficiency of tariffs and present evidence of how pricing has changed in markets with retail choice
