Retirement in the UK

In common with other OECD countries, the UK experienced morethan two decades of declining labour-market activity among oldermen from the 1970s to the early 1990s, a trend that has onlyrecently shown signs of being reversed. Retirement decisionsare heavily shaped by institutional context and in the UK thishas led to there being two distinct groups with very different‘retirement’ experiences. At the top of the wealthdistribution, early retirement has typically been influencedby private, occupational pensions; at the bottom of the wealthdistribution individuals are even more likely to be not workingin their 50s, but do not typically define themselves as retired,and draw on income support, or more usually, disability benefits.Policy-makers keen to increase effective retirement ages willneed to consider the very different circumstances of these twogroups.

Doing Design Thinking: Conceptual Review,Synthesis, and Research Agenda

Design thinking has attracted considerable interest from practitioners and academics alike, as it offers a novel approach to innovation and problem‐solving. However, there appear to be substantial differences between promoters and critics about its essential attributes, applicability, and outcomes. To shed light on current knowledge and conceptualizations of design thinking we undertook a multiphase study. First, a systematic review of the design thinking literature enabled us to identify 10 principal attributes and 8 tools and methods. To validate and refine our findings, we then employed a card sorting exercise with professional designers. Finally, we undertook a cluster analysis to reveal structural patterns within the design thinking literature. Our research makes three principal contributions to design and innovation management theory and practice. First, in rigorously deriving 10 attributes and 8 essential tools and methods that support them from a broad and multidisciplinary assortment of articles, we bring much needed clarity and validity to a construct plagued by polysemy and thus threatened by “construct collapse.” Second, aided by the identification of perspectives of scholars writing about design thinking, we provide detailed recommendations for relevant topics warranting further study in order to advance theoretical understanding of design thinking and test its applications. Third, we identify the enduring, yet essential, questions that remain unresolved across the extant design thinking literature and that may impede its practical implementation. We also provide suggestions for the theoretic frames, which may help address them, and thus advance the ability of scholars and managers alike to benefit from design thinking’s apparent advantages.     

Local Immigration Enforcement and Local Economies

We examine the impacts of a locally enforced immigration program—287(g)—on private employer reports to the Quarterly Census of Employment and Wages. Using contiguous‐county pairs to account for time‐varying local economic shocks, we identify impacts on immigrant‐intensive industries that are robust to prepolicy time trends, implementation timing, and the exclusion of pairs with large prepolicy differences. Reported employment was 4 percent higher in manufacturing, but 7–10 percent lower in administrative services. These results are consistent with adverse labor‐supply shocks, and, to a lesser extent, a decline in labor demand for locally produced goods and services.     

Costs and benefits of internal control audits: evidence from M&A transactions

To inform the debate on the merits of internal control audits, we examine managers’ decisions to temporarily exempt newly acquired businesses from Section 404 of the Sarbanes-Oxley Act. We document that managers are more likely to elect the exemption when expected compliance costs are higher, such as when acquisitions are larger and occur later in the year. We find only modest evidence that managers use the exemption to avoid scrutiny of value-destroying deals. Exemption use, however, is associated with negative post-acquisition outcomes, including lower return-on-assets and higher likelihoods of goodwill impairments and financial statement restatements. These results comport with compliance providing benefits by facilitating timely identification and correction of control problems in the newly acquired business. Finally, we document negative abnormal stock returns at the time exemption use is announced and over the subsequent 3 years, suggesting that investors view exemption use negatively and that their initial price reactions are incomplete.     

Asymmetric news responses of high‐frequency and non‐high‐frequency traders

Using NASDAQ trade and Reuters news data, I show that the response of aggressive non‐high‐frequency traders (nHFTs) to news is stronger than that of aggressive high‐frequency traders (HFTs). Classifying news into quantitative (“hard”) and less quantitative (“softer”) news, the trading response of aggressive nHFTs to softer news exceeds HFTs’ response. Positive news elicits greater return and nHFT responses than negative news during the 2008 financial crisis period. As this phenomenon persists even after excluding the 2008 short‐sale ban, the results support the hypothesis of nHFTs exhibiting stronger asymmetric responses during crisis periods.

Why Can't I Trade? Exchange Discretion in Calling Halts*,†

Stock exchanges are important intermediaries in how firm information enters price. Trading halts are a key tool, often exercised at the exchanges' discretion, to prevent extraordinary price volatility when new information arrives. We investigate how exchanges use discretion and whether the discretion alters the effectiveness of the halts. We provide evidence consistent with halts reflecting the preferences of listed firms rather than the stated exchange objectives (i.e., minimizing excess volatility and off-equilibrium trades). Furthermore, when exchanges exercise more discretion (unexplained by firm and information characteristics), the halts are less effective. Specifically, halts with more discretion are less likely to resume trading with efficient prices and are more likely to have been called unnecessarily (i.e., little to no price movement during the halt). These findings are consistent with exchanges using halts to cater to listed firms rather than to meet exchange objectives such as minimizing excess volatility or avoiding trades at off-equilibrium prices.

Income disclosure and consumer judgment in a multilevel marketing experiment

Consumer protection concerns have been raised related to income misrepresentation in multilevel marketing (MLM) recruitment. Though not required by law, some MLM firms choose to voluntarily disclose income information about previous participants. Through replication and extension of the experiment created in Bosley, Greenman, and Snyder (2020), we investigate the impact of these disclosures on consumer interest and earnings expectations. We test the external validity of their findings with subjects from Mechanical Turk and explore issues regarding treatment heterogeneity and better-than-average bias. Supporting prior findings, we present evidence that income disclosures, on average, do not significantly affect subjects' interest in the MLM opportunity, but they do decrease earnings estimates for most while increasing earnings estimates for a few. These effects depend on a subject's numeracy skills and whether they see their earnings potential as better-than-average. We also find that asking about earnings estimates first tends to decrease interest.     

Overcoming data barriers in spatial agri-food systems analysis: A flexible imputation framework

Suppressions in public data severely limit the usefulness of spatial data and hinder research applications. In this context, data imputation is necessary to deal with suppressed values. We present and validate a flexible data imputation method that can aid in the completion of under-determined data systems. The validations use Monte Carlo and optimisation modelling techniques to recover suppressed data tables from the 2017 US Census of Agriculture. We then use econometric models to evaluate the accuracy of imputations from alternative models. Various metrics of forecast accuracy (i.e., MAPE, BIC, etc.) show the flexibility and capacity of this approach to accurately recover suppressed data. To illustrate the value of our method, we compare the livestock water withdrawal estimations with imputed data and suppressed data to show the bias in research applications when suppressions are simply dropped from analysis.
