Choosing to Re‐Experience Movies and TV Episodes
Volitional reconsumption—the deliberate choice to rewatch movies and television episodes already seen—is an increasingly common and economically significant form of contemporary media use enabled by on‐demand and mobile streaming. This article synthesizes research tracing how reconsumption has evolved from broadcast‐era reruns to a personalized, algorithmically‐supported behavior and clarifies the conceptual distinctions among repeat viewing, vol…

Relationship Lending and the Great Depression
The collapse of long-term lending relationships amplified the Great Depression. We demonstrate this by developing a new measure of lending relationships that can be calculated from widely available data at any level of aggregation. Our approach exploits differences in the responsiveness of loan rates to bank funding costs and is supported by historical evidence and theoretical arguments. The new measure reveals that the marginal impact of bank su…

Can China's Covid-19 strategy work elsewhere?
Rapid decline in cases is real, expert mission concludes—but it came at a high cost.
Countries test tactics in ‘war’ against Covid-19
Lockdowns and closings proliferate, but virus testing and contact tracing are lagging.
Economics and the Historian
These essays provide a thorough introduction to economics for historians. The authors, all eminent scholars, show how to use economic thinking, economic models, and economic methods to enrich historical research. They examine such vital issues as long-term trends, institutions, labor—including an engaging dialogue between a labor historian and a labor economist—international affairs, and money and banking. Scholars and teachers of history will we…
The Medium Is the Measure
New indicators, based on technology titles, are used to measure the impact of innovative activity on the U.S. labor market between 1909 and 1949. We find that positive technology shocks raised productivity, employment, vacancies, and labor turnover and lowered unemployment and business failures. Moreover, automotive and electrical innovations (quintessential general-purpose technologies) had a greater positive impact on employment than those in m…
Impact of Web Survey Invitation Design on Survey Participation, Respondents, and Survey Responses
This article investigates how webpages shown to respondents before they enter a self-administered survey impact whether and how they respond. Using the SurveyMonkey “end page,” a page that is displayed nearly 3 million times daily to survey respondents who have completed a user-created survey, this article examines whether the type of image and text that are displayed on the end page has a large impact on survey participation, whether different i…
Centralised wage bargaining and structural change in Sweden
There is a general consensus among scholars that centralised wage bargaining played a key role in the ability of Sweden to maintain wage moderation in the early post-World War II period. Conventional wisdom suggests that it worked through one of two mechanisms: internalisation of the negative externalities associated with excessive wage settlements or implicit contracts that favoured cooperation between capital and labour over conflict. We conten…

A comparison between carboxyhemoglobin and serum thiocyanate determinations as indicators of cigarette smoking
Cigarette smoking histories were compared to carboxyhemoglobin and serum thiocyanate concentrations obtained from 426 smokers and 191 non-smokers. The mean levels of both carboxyhemoglobin and serum thiocyanate wefe significantly higher among cigarette smokers and correlated with number of cigarettes smoked per day. The specificity of both procedures was 81 per cent, and serum thiocyanate had a higher sensitivity (93 per cent vs. 83 per cent), ma…
Cigarette smoking among medical students
A survey of first and second year medical students at Saint Louis University revealed that only 6 per cent were current cigarette smokers. This represents a continuation of a downward trend in the percentage of smokers among American medical students as reported in earlier, independent surveys. Implications for improved health status and for better preventive care for patients by these future physicians are discussed
