The conference paper by Gerakos, Lang and Maffett (2013) provides reliable, descriptive evidence on the post-IPO performance of firms listing on the London Stock Exchange's Alternative Investment Market (AIM). Their findings are consistent with both a failure of private sector regulation and incorrect market expectations about AIM's investor protections. In this discussion of Gerakos et al. (2013), I highlight the strengths and limitations of their conference paper, summarize how various regulatory and market factors could produce the observed systematic under-performance of AIM offerings, and outline paths for future research on the topic.

The public arrest of Adelphia executives on July 24, 2002 signaled tougher enforcement of laws against corporate crime. On that day and the two following days, foreign firms experienced a cumulative 1.7% decline in value. Relative to domestic firms, the loss was a much larger 4.5%. The expected cost to firms from tougher enforcement suggests three possible reasons. Foreign firms may be targeted more heavily, may face greater penalties, or may find it more costly to react to (deflect) enforcement. We find evidence consistent with foreign firms facing higher costs from tougher enforcement for each of these reasons.

We measure the effect of bank failures on economic growth using data from 1900 to 1930, a period without active government stabilization policies and several severe banking crises. VAR model estimates suggest bank failures have long-lasting negative effects on economic growth. A bank failure shock involving one percent of system liabilities leads to a 6.5% reduction in GNP growth within three quarters and a measurable reduction for 10 quarters. Panel VAR model estimates for the 48 states show bank failures aggravate commercial non-bank failures. Institutional and regulatory features affect the intensity of the bank failure effect. We find that bank failures have a larger impact in states with deposit insurance, in states more heavily concentrated in agriculture, and in states with fewer large firms. However, because a number of states exhibit all three characteristics, we are not able to clearly identify the true marginal effects of these factors independently.

The Federal Reserve’s 2009 program to purchase $300 billion of US Treasury securities represented an unprecedented intervention in the Treasury market and provides a natural experiment with the potential to shed light on the price elasticities of Treasuries and theories of supply effects in the term structure. Using security-level data on Treasury prices and quantities during the course of this program, we document a ‘local supply’ effect in the yield curve—yields within a particular maturity sector responded more to changes in the amounts outstanding in that sector than to similar changes in other sectors. We find that this phenomenon was responsible for a persistent downward shift in yields averaging about 30 basis points over the course of the program (the “stock effect”). In addition, except at very long maturities, purchase operations caused an average decline in yields in the sector purchased of 3.5 basis points on the days when those operations occurred (the “flow effect”). The sensitivity of our results to security characteristics generally supports a view of segmentation or imperfect substitution within the Treasury market during this time.

Institutional investors exhibit substantial home-state bias in private equity. This effect is particularly pronounced for public pension funds, where overweighting amounts to 9.8% of aggregate private-equity investments and 16.5% for the average limited partner. Public pension funds' in-state investments achieve performance that is lower by two to four percentage points than both their own similar out-of-state investments and similar investments in their state by out-of-state investors. Overweighting in home-state investments by public pension funds is greater in venture capital and real estate than in buyout funds. States with political climates characterized by more self-dealing invest a larger share of their portfolio in local investments, although a given local investment performs only as poorly in these states as in other states. Relative to the performance of the rest of the private equity universe, overweighting and underperformance in local investments reduce public pension fund resources by $1.2 billion per year.

In an economy with distortionary taxes on labour, can subsidies on day care, financed by increased taxes, raise welfare by encouraging women with small children to work? We show, within a stylized life-cycle framework, that the Ramsey optimal policy consists in equalizing consumption/leisure wedges over the life cycle. A simple way to implement this is to make day care expenses tax deductible. Modifying and calibrating our model to fit some key facts about labour supply in Germany, we find that the reform that maximizes a distribution-neutral social welfare function involves subsidizing day care at a rate of 50% and leads to a near doubling of labour supply for mothers with small children. The overall welfare gain from this reform corresponds to a 0.4 percent increase in consumption.

This study investigates the role of financial reporting quality in merger and acquisition (M&A) deals that are ultimately terminated (i.e., go bust). If a target is a U.S. publicly traded company, an acquirer’s initial assessment of the potential benefits associated with the acquisition of the company is based on publicly available information. Generally, the acquirer obtains limited private information from the target prior to announcing the deal, but engages in transactional due diligence after signing the acquisition agreement to affirm that the financial reporting warranties made by the target are accurate. We construct a low‐quality financial reporting score based on measures prior research identifies as being associated with less reliable, less relevant, and less precise financial reporting. We find that acquirers offer higher premiums for targets with low‐quality financial reporting. However, we also find that low‐quality financial reporting increases the likelihood of deal renegotiation, and contributes to the probability of deals going bust. We document that failed targets are more likely to restate their financial statements after the announcement of the deal, supporting our conjecture that low‐quality financial reporting contributes to deals being terminated. Our research develops a new measure of low‐quality financial reporting, documents that the measure is related to M&A deal outcomes and financial restatements, and provides insights into the consequences of M&A transactional due diligence.

Signaling undervaluation is often considered a primary motive for repurchasing stock, but insider trading activity by repurchasing firms is not always consistent with undervaluation. Net insider buying and selling are both more frequent in quarters when firms are repurchasing non-trivial amounts of stock, with the odds of observing a repurchase the highest in quarters with net insider selling. In multinomial logit models, share repurchases associated with net insider selling are positively related to illiquidity, option exercises by insiders, and pre-repurchase returns and negatively correlated with industry-adjusted book to market ratios when compared to other repurchases. Hence, repurchases when insiders are selling stock are more likely done to support share prices or avoid dilution and are less likely undervaluation signals. We find that insider trades either validate or mitigate the undervaluation signal of the repurchase. Abnormal returns of repurchasing firms with net insider buying versus net insider selling in a given quarter are significantly higher for the quarter immediately after the repurchase and the three subsequent years. For repurchases accompanied by net insider selling, abnormal returns are negligible after only one year.

Luck, skill and labor markets all have empirical support as determinants of managerial compensation. We examine the relative importance of pay for luck, managerial skill and labor market opportunities in determining compensation. We measure luck as the predictable component of firm performance, measure skill using managerial fixed effects and measure labor market opportunities as the compensation of executives at matched firms. Our results imply that managerial skill is the most important determinant of managers' compensation, followed by firm size and labor market opportunities, and that luck is not an important determinant of managerial compensation.
