Control groups can provide counterfactual evidence for assessing the impact of an event or policy change on a target variable. We argue that fitting a multivariate time series model offers potential gains over a direct comparison between the target and a weighted average of controls. More importantly, it highlights the assumptions underlying methods such as difference in differences and synthetic control, suggesting ways to test these assumptions. Gains from simple and transparent time series models are analysed using examples from the literature, including the California smoking law of 1989 and German reunification. We argue that selecting controls using a time series strategy is preferable to existing data‐driven regression methods.  相似文献

Differences in accrued gains and investors’ tax-sensitivity induce variation in a capital gains lock-in effect across mutual funds even for the same stock at the same time. Exploiting this variation, we show this effect influences funds’ governance decisions: higher capital gains decrease the likelihood a fund exits prior to contentious votes and increase the likelihood a fund votes against management. Consistent with tax motivation, these findings are concentrated among funds with tax-sensitive investors. Further, high aggregate capital gains across funds holding a stock predict a higher likelihood management loses a vote and a lower likelihood a contentious vote is proposed.  相似文献

This paper develops a two‐sector model of trade in goods and intermediate tasks that differ in tradability and skill intensity. A skill‐abundant country with high productivity is shown to offshore more unskilled tasks than skilled tasks, without relying on a particular correlation structure between tradability and skill intensity. With putty‐clay technology that allows retraining in the long run, transition from the non‐offshoring to the offshoring equilibrium generates wage and employment effects that switch from negative to positive as tradability declines, with the switches occurring at a higher degree of tradability for skilled tasks. This is consistent with the empirical literature.  相似文献

This study evaluates the impact of an automated reminder program designed to help credit counseling consumers manage their payment obligations and financial goals. Credit counseling consumers were randomly assigned to receive reminders linked to their financial goals and payment obligations for one year after an initial credit counseling session. We find that consumers offered reminders were 21% less likely than the control to experience severe (60+ day) payment delinquencies and were 12% less likely to experience a 30+ day delinquency. At the same time, these consumers saw a 10.5 point increase in credit scores relative to the control group. There were no significant impacts on total credit card balances or installment debt levels. This analysis provides promising evidence that automated reminders can provide an important complement to traditional credit counseling when it comes to improving consumers' credit profiles and does so at a fairly low cost.  相似文献

This study endeavors to enhance political marketing literature about the impact of lobbying on firm performance. Our sample is composed of 140 U.S. firms and spans the years 2007–2014 to encompass the 2007–2009 recession and the subsequent recovery period. Our findings indicate that lobbying expenses positively contribute to firm performance. Also, government contracts in both ways, dollar amount and number of government contracts, act as mediators between lobbying expenses and firm performance. In addition, organizational slack moderates the relationship between lobbying expenses and government contracts. The managerial implications suggest that lobbying expenses can be leveraged as a potent tool for firm performance. Firms with larger lobbying efforts acquired both, higher dollar amounts and a greater number of government contracts.  相似文献

This article develops a posthuman approach to authorship to challenge implied distinctions and superiorities between the social and material worlds, which can detach academics and their writing from societies and ecosystems. By reimagining academic texts that are open for richer interpretation and accessible to diverse audiences, this article offers two main contributions. Firstly, I develop a conceptualisation of the posthuman author as an 'unbounded gatherer', adding to others' attempts to destabilise predominant humanistic ways of writing about managing and organizing that view authors as autonomous agents. Secondly, by developing the idea of 'mediators' as a means to explore how the sociomaterial is implicated in writing, debates about materiality in writing are extended. Through an illustration of posthuman writing, five emergent categories of mediators are analysed, and three textual practices are performed and examined.  相似文献

The effects of selected high‐performance practices and working hours on work–life balance are analysed with data from national surveys of British employees in 1992 and 2000. Alongside long hours, which are a constant source of negative job‐to‐home spillover, certain ‘high‐performance’ practices have become more strongly related to negative spillover during this period. Surprisingly, dual‐earner couples are not especially liable to spillover — if anything, less so than single‐earner couples. Additionally, the presence of young children has become less important over time. Overall, the results suggest a conflict between high‐performance practices and work‐life balance policies.  相似文献
