The Structure of Sprawl: Identifying and Characterizing Employment Centers in Polycentric Metropolitan Areas

This paper applies a consistent framework to four comparably sized metropolitan areas to identify and characterize their employment centers. Employment centers are identified as places that exceed a threshold employment density and a threshold employment level. They are also characterized as specializing on the basis of location quotient analysis. We find clear evidence of specialization in every employment center in the four metropolitan areas studied. Our interpretation is that what we are observing is a systematic change in metropolitan structure rather than a random sprawling of firms. We also find some evidence that the size distribution of employment centers follows the rank-size rule. This suggests that there is structure not only in the distribution of economic activity among the employment centers but also in their size distribution. Because less than 50 percent of metropolitan employment is within employment centers, future research should focus on understanding the more diffuse employment patterns. The rank-size rule gives some guidance as to the expected size distribution of employment throughout the metropolitan area.     

Selectivity and timing performance of UK investment trusts

This study examines the selectivity and timing performance of 218 UK investment trusts over the period July 1981 to June 2009. We estimate the Treynor and Mazuy (1966) and Henriksson and Merton (1981) models augmented with the size, value, and momentum factors, either under the OLS method adjusted with the Newey–West procedure or under the GARCH(1,1)-in-mean method following the specification of Glosten et al. (1993; hereafter GJR-GARCH-M). We find that the OLS method provides little evidence in favour of the selectivity and timing ability, consistent with previous studies. Interestingly, the GJR-GARCH-M method reverses this result, showing some relatively strong evidence on favourable selectivity ability, particularly for international funds, as well as favourable timing ability, particularly for domestic funds. We conclude that the GJR-GARCH-M method performs better in evaluating fund performance compared with the OLS method and the non-parametric approach, as it essentially accounts for the time-varying characteristics of factor loadings and hence obtains more reliable results, in particular, when the high frequency data, such as the daily returns, are used in the analysis. Our results are robust to various in-sample and out-of-sample tests and have valuable implications for practitioners in making their asset allocation decisions across different fund styles.     

Fire sale acquisitions: Myth vs. reality

We provide empirical evidence on the conjecture that in economic crises, firms could be forced to sell at deep discounts, or fire sale prices. Using the conventional stock price near the announcement date, we find instead distressed firms in crisis periods receive a 30% higher offer premium than distressed firms in normal periods; they also receive a 34% higher premium than non-distressed firms in crisis periods. Acquirers also do not gain, at announcement and over the long-term. Acquirers, however, may perceive they realize fire sale discounts if the reference is the targets’ highest price in the previous 52 weeks.     

Sovereign wealth fund investment and the return-to-risk performance of target firms

This paper investigates the relationship between sovereign wealth fund (SWF) investment and the return-to-risk performance of target firms. Specifically, we find that target firm raw returns decline following SWF investment. Though risk also declines following SWF investment, we find that SWF investment is associated with a reduction in the compensation of risk over the 5 years following acquisition. Firm volatility decomposition suggests that idiosyncratic risk is what mainly drives these impacts toward decline. Employing a multinomial logit framework wherein combinations of target returns and risk movements are categorized, we see that, in cases of foreign investment, SWFs’ target firm performance most closely resembles that of other government-owned firms. The observed results are inconsistent with predictions of higher volatility and improved returns due to monitoring firm activities from the institutional investor literature. This suggests that SWFs may not provide some of the benefits that are offered by other institutional investors.     

Measuring sustainability: Why the ecological footprint is bad economics and bad environmental science

The ecological footprint is a measure of the resources necessary to produce the goods that an individual or population consumes. It is also used as a measure of sustainability, though evidence suggests that it falls short. The assumptions behind footprint calculations have been extensively criticized; I present here further evidence that it fails to satisfy simple economic principles because the basic assumptions are contradicted by both theory and historical data. Specifically, I argue that the footprint arbitrarily assumes both zero greenhouse gas emissions, which may not be ex ante optimal, and national boundaries, which makes extrapolating from the average ecological footprint problematic. The footprint also cannot take into account intensive production, and so comparisons to biocapacity are erroneous. Using only the assumptions of the footprint then, one could argue that the Earth can sustain greatly increased production, though there are important limitations that the footprint cannot address, such as land degradation. Finally, the lack of correlation between land degradation and the ecological footprint obscures the effects of a larger sustainability problem. Better measures of sustainability would address these issues directly.     

Capabilities,technologies, and firm exit during industry shakeout: Evidence from the global solar photovoltaic industry

Research Summary: Explanations of entrants’ survival in an emerging industry are premised on pre‐entry capabilities or technology entry choices prior to the emergence of the dominant design. We consider how these drivers interact to strengthen or nullify firms’ pre‐entry advantage, and facilitate adaptation as the industry evolves. We also expand the treatment of exit by separating dissolution from acquisition, in which firms’ capabilities continue to be utilized in the industry. Studying a recent shakeout in the global solar photovoltaic industry, we find that pre‐entry capabilities and technology choices act in a complementary manner for some firms, thereby enhancing survival, and as buffers against exit for others. Nearly half of exits were via acquisitions, and technology choice at entry played an important role in determining how firms exited. Managerial Summary: New industries are often characterized by intense technology competition that culminates in a dominant technology followed by industry shakeout. Although prior research underscores the central role of technology choice and firm capabilities to survival, we do not actually know how firms with different capabilities and who have made competing technology choices survive an industry shakeout. In this article, we show how entrants’ capabilities and technology choices can act in a complementary manner for some firms, enhancing their chance of survival, and as buffers against failure for others. Moreover, we explain why some firms that do exit are acquired, when others are dissolved.     

Evaluating the flipped classroom: A randomized controlled trial

Despite recent interest in flipped classrooms, rigorous research evaluating their effectiveness is sparse. In this study, the authors implement a randomized controlled trial to evaluate the effect of a flipped classroom technique relative to a traditional lecture in an introductory undergraduate econometrics course. Random assignment enables the analysis to eliminate other potential explanations of performance differences between the flipped and traditional classrooms, while assignment of experimental condition by section and lesson enables improved statistical precision. The authors find that the flipped classroom increases scores on medium-term, high-stakes assessments by 0.16 standard deviation, with similar long-term effects for high-performing students. Estimated impacts are robust to alternative specifications accounting for possible spillover effects arising from the experimental design.     

Audit Regulation and Cost of Equity Capital: Evidence from the PCAOB's International Inspection Regime*

This study investigates the relation between audit regulation and cost of equity capital. There is scant empirical evidence on this relation because changes in audit regulation are frequently accompanied by other major regulatory changes. We exploit variation in the timing of regulatory changes induced by foreign governments' staggered allowance of PCAOB inspections. Using a difference-in-differences design, we find that foreign SEC registrants with auditors from countries that allow PCAOB inspections enjoy a lower cost of capital, relative to foreign SEC registrants with auditors from countries that prohibit inspections. Furthermore, we find that this cost of capital effect is attenuated for companies with higher-quality governance mechanisms. Finally, we document that inspection access is associated with higher-quality analyst forecasts, which suggests that this change in audit regulation reduces information risk for market participants.
