Earlier studies have linked equity market liberalization to growth in emerging markets. Some conclude liberalization causes growth, whereas others contend contemporaneous economic policies and conditions play important roles. The causal argument contends that foreigner investability in public firms leads to lower discount rates and greater share issuance, investment, and efficiency. Using three separate measures of foreign investability, we do not find these effects. Moreover, common de jure foreigner-investability measures are poor de facto measures. Economic indicators, not directly influenced by equity market liberalization, also grow faster in countries with more investable firms. Our findings suggest foreigner investability cannot fully explain the equity-market-liberalization-growth relation.

Berk and Green (2004) make a theoretical argument that performance persistence should not exist since new money flows into well-performing mutual funds and there are diseconomies of scale, or because successful funds capture excess returns by raising fees. We find that performance prediction continues when we examine samples of larger and larger funds and that past performance predicts future performance for holding periods up to three years. Funds that outperform index funds of the same risk can be identified. We find that expense ratios are lower for large funds, and decrease as funds get larger or perform well.

This paper examines trends in union membership during the twentieth century. The hypothesis is advanced that the provision of certain social welfare benefits by government substitutes for the private provision by unions, thereby reducing the attractiveness of union membership. The empirical implications of this hypothesis are examined using time-series data on aggregate union membership for the period 1904-80 and using pooled state data for the period 1964-80. These latter data are used to examine the effect of departures from the traditional doctrine of "employment at will." Both the time-series and the cross-section evidence suggest that government supply of "union-like" services reduces union membership.

While it is tempting to focus on new financial innovations in helping explain recent financial turmoil, more traditional causes should not be overlooked. As on many previous occasions, very rapid credit growth led to major increases in asset prices, which in turn encouraged consumption and investment decisions which could yet prove unsustainable. The natural “procyclicality” of the financial system could perhaps be contained through the introduction of a “new macrofinancial stability framework”. There are many practical impediments to realising such a suggestion, but there are also grounds for belief that these impediments could be removed.

We distinguish between identification and establishing causality. Identification means forming a unique mapping from features of data to quantities that are of interest to economists. Establishing causality by finding sources of exogenous variation is often considered synonymous with identification, but these two concepts are distinct. Exogenous variation is only sometimes necessary and never sufficient to identify economically interesting parameters. Instead, even for causal questions, identification must rest on an underlying economic model. We illustrate these points by analyzing identification in three recent papers and by examining the estimation of a simple dynamic model.

In almost every area of empirical finance, researchers confront multiple tests. One high-profile example is the identification of outperforming investment managers, many of whom beat their benchmarks purely by luck. Multiple testing methods are designed to control for luck. Factor selection is another glaring case in which multiple tests are performed, but numerous other applications do not receive as much attention. One important example is a simple regression model testing five variables. In this case, because five variables are tried, a t-statistic of 2.0 is not enough to establish significance. Our paper provides a guide to various multiple testing methods and details a number of applications. We provide simulation evidence on the relative performance of different methods across a variety of testing environments. The goal of our paper is to provide a menu that researchers can choose from to improve inference in financial economics.

As a result of poor asset allocation decisions by 401(k) participants, 72% of all plans now offer target date funds, and participants heavily invest in them. Here, we study the characteristics and performance of TDFs, providing a unique view by employing data on TDFs holdings. We show that additional expenses charged by TDFs are largely offset by the low-cost share classes they hold, not normally open to their investors. Additionally, TDFs are very active in their allocation decisions and increasingly bet on nonstandard asset classes. However, TDFs do not earn alpha from timing or their selection of individual assets.

Diversification by banks affects the systemic risk of the sector. Importantly, Wagner (2010) shows that linear diversification increases systemic risk. We consider the case of securitization, whereby loan portfolios are sliced into tranches with different seniority levels. We show that tranching offers nonlinear diversification strategies, which can reduce the failure risk of individual institutions beyond the minimum level attainable by linear diversification without increasing systemic risk.

Considerable research has documented the role of debt covenants and conservative financial accounting in addressing agency conflicts between lenders and borrowers. Beatty, A., Weber, J., and Yu, J. [2008. Conservatism and debt. Journal of Accounting and Economics, forthcoming] document interesting, but mixed, findings on the relation between debt covenants and conservative accounting, and the extent to which the two contracting mechanisms act as substitutes or complements. In this paper, I discuss the economic roles of financial reporting, debt covenants, and conservatism within the debt contracting environment, and attempt to fit BWY's findings within this context.
