The Self-Sufficiency Project (SSP) was a well-known welfare-to-work experiment that provided a generous but time-limited financial incentive to leave welfare and enter the workforce. Experimental evidence showed large short-term impacts but no lasting effects. We argue that these conclusions need to be reassessed. Policy changes implemented during the SSP implied that the control group’s behavior did not provide an appropriate counterfactual. We estimate the impacts the financial incentive would have had in an unchanging policy environment. This reassessment leads to significant changes in the lessons previously reached. Our study demonstrates that experimental findings need to be interpreted with care.

This paper examines the effect of a regulatory action (the Home Valuation Code of Conduct) that was designed to reduce the incidence of inflated collateral valuations. We identify the impact of the regulation using a difference-in-difference identification strategy. Our baseline results confirm that the regulation reduced inflated valuations in refinance transactions by 16% in the large lender sample, compared to small lenders and a placebo sample. The effect is most significant in low-liquidity and low-distress markets, but not in other markets. We find that the regulation had a significant impact on loan to value ratio and interest rate, and it also led to a significant increase in defaults but a decrease in prepayments.

In this essay I discuss potential outcome and graphical approaches to causality, and their relevance for empirical work in economics. I review some of the work on directed acyclic graphs, including the recent The Book of Why (Pearl and Mackenzie 2018). I also discuss the potential outcome framework developed by Rubin and coauthors (e.g., Rubin 2006), building on work by Neyman (1990 [1923]). I then discuss the relative merits of these approaches for empirical work in economics, focusing on the questions each framework answers well, and why much of the the work in economics is closer in spirit to the potential outcome perspective.

The purpose of this study is to provide empirical evidence on the links between currency and banking crises. Panel data probit and bivariate probit models are estimated to a sample of 21 developed and developing countries having monthly observations between the years 1985 and 2010. The findings indicate that banking crises precede currency crises, and vice versa. Currency crises also indirectly influence future banking crises probability through external shocks, liberalized financial markets, or highly-leveraged banking sectors. The study also finds evidence of contemporaneous correlation between the two crises. The results not only confirm the theoretical links between banking and currency crises, but also underline the importance of higher frequency data in analyzing the relationship between various financial crises.

New evidence from acquisition decisions suggests that antitakeover provisions (ATPs) may increase firm value when internal corporate governance is sufficiently strong. We document that, in Germany, firms with stronger ATPs, and particularly supermajority provisions, are better acquirers. Managers of high-ATP firms create value in acquisitions by making governance-improving deals. They are more likely to engage in acquisitions that reduce their own entrenchment level and less likely to invest in declining industries. The empirical evidence is consistent with a short-termist interpretation. Takeover threats can induce myopic investment decisions, which ATPs can mitigate. They lead managers to engage more often in value-creating long-term and innovative investing, and increase a firm's sensitivity to investment opportunities. Our findings contribute to a growing literature challenging conventional wisdom that the agency-increasing effect of ATPs empirically dominates the myopia-eliminating effect, suggesting that a more contextual view of the value implications of ATPs is necessary.

Using a novel dataset on global private equity investments in 19 industries across 52 countries, we find that labor productivity, employment, profitability, and capital expenditures increase for publicly-listed companies in the same country and industry as private equity investments. Our results show that positive externalities created by private equity firms are absorbed by other companies within the same industry. Consistent with prior literature on competitive spillovers, these effects are more pronounced in country-industries with higher levels of competition, stronger institutions, and moderate levels of technological development suggesting that the competitive pressures from private equity-backed firms cause industry peers to react.

We investigate claims made in Giacomini and White (2006) and Diebold (2015) regarding the asymptotic normality of a test of equal predictive ability. A counterexample is provided in which, instead, the test statistic diverges with probability 1 under the null.

We introduce a novel concept of network interactions in which board connections provide access to external spheres of political influence, state ownership, and family control. We posit this form of indirect access via board association enables connected firms to benefit from information privy to external networks while avoiding their resource-based costs of membership. Board network data are assembled for 1290 East Asian firms and linked to hand-collected data on political connections and corporate ownership around the 2008–09 crisis. Companies with board connections to state-owned firms and family business groups had greater crisis-period accounting performance and stock returns. In countries with weak institutional development, board connections to politically connected firms were also beneficial.

We study the consequences of a 2010 change in the investment adviser qualification exam that reallocated coverage from the rules and ethics section to the technical material section. Comparing advisers with the same employer in the same location and year, we find those passing the exam with more rules and ethics coverage are one-fourth less likely to commit misconduct. The exam change appears to affect advisers’ perception of acceptable conduct and not just their awareness of specific rules or selection into the qualification. Those passing the rules and ethics-focused exam are more likely to depart employers experiencing scandals. Such departures also predict future scandals. Our paper offers the first archival evidence on how rules and ethics training affects conduct and labor market activity in the financial sector.
