The Mirrlees Review of taxation in the United Kingdom is a landmark in the analysis of U.K. fiscal policy, and of wide interest to public finance economists around the world. This review concentrates on what we can learn from the Review about the current state of public economics and directions for future research. (JEL E62, H20, H50)

The subprime crisis highlights how little we know about bank governance. This paper addresses a long-standing gap in the literature by analyzing the relationship between board governance and performance using a sample of banking firm data that spans 34years. We find that board independence is not related to performance, as measured by a proxy for Tobin’s Q. However, board size is positively related to performance. Our results are not driven by M&A activity. But, we provide new evidence that increases in board size due to additions of directors with subsidiary directorships may add value as BHC complexity increases. We conclude that governance regulation should take unique features of bank governance into account.

This study provides empirical evidence on the role of disclosure in resolving agency conflicts in delegated investment management. For certain expenditures, fund managers have alternative means of payment which differ greatly in their opacity: payments can be expensed (relatively transparent); or bundled with brokerage commissions (relatively opaque). We find that the return impact of opaque payments is significantly more negative than that of transparent payments. Moreover, we find a differential flow reaction that confirms the opacity of commission bundling. Collectively, our results demonstrate the importance of transparency in addressing agency costs of delegated investment management.

Institutional trading arrangements often involve the portfolio manager delegating the task of trade execution to a separate division within the firm. We model the agency conflict that arises in this setting and show that optimal performance benchmarks often create an incentive to execute orders contrary to concurrent information flow. We hypothesize that aggregate contrarian trading resulting from widespread application of such benchmarks leads to delays in the assimilation of information in security prices. Using institutional trading data, we document the hypothesized contrarian trading pattern and relate the pattern to price-adjustment delays in the response of individual stocks to index futures returns. The evidence supports the assertion that delegated institutional trading contributes to these delays.

Firms that intentionally increase leverage through substantial debt issuances do so primarily as a response to operating needs rather than a desire to make a large equity payout. Subsequent debt reductions are neither rapid, nor the result of proactive attempts to rebalance the firm’s capital structure toward a long-run target. Instead, the evolution of the firm’s leverage ratio depends primarily on whether or not the firm produces a financial surplus. In fact, firms that generate subsequent deficits tend to cover these deficits predominantly with more debt even though they exhibit leverage ratios that are well above estimated target levels. Our findings are broadly consistent with a capital structure theory in which financial flexibility, in the form of unused debt capacity, plays an important role in capital structure choices. (JEL G32) The search for an empirically viable capital structure theory has confounded financial economists for decades. Standard trade-off models of capital structure have been criticized on the grounds that they do a poor job of explaining observed debt ratios. For example, traditional trade-off models have difficulty explaining why firms tend to issue stock after exogenous decreases in leverage

In this article we present a simple new Keynesian–style model of debt-driven slumps—that is, situations in which an overhang of debt on the part of some agents, who are forced into rapid deleveraging, is depressing aggregate demand. Making some agents debt-constrained is a surprisingly powerful assumption. Fisherian debt deflation, the possibility of a liquidity trap, the paradox of thrift and toil, a Keynesian-type multiplier, and a rationale for expansionary fiscal policy all emerge naturally from the model. We argue that this approach sheds considerable light both on current economic difficulties and on historical episodes, including Japan’s lost decade (now in its 18th year) and the Great Depression itself.

To fully understand the motives for delegating a decision right, it is important to study responsibility attributions for outcomes of delegated decisions. We conducted laboratory experiments in which subjects could either choose a fair allocation or an unfair allocation or delegate the choice, and we used a punishment option to elicit responsibility attributions. Our results show that, first, responsibility attribution can be effectively shifted and, second, this can constitute a strong motive for the delegation of a decision right. Moreover, we propose a simple measure of responsibility and show that this measure outperforms measures based on inequity aversion or reciprocity in predicting punishment behaviour.
