The Green Revolution and Individualism: Evidence from Indonesia
The Green Revolution and Individualism: Evidence from Indonesia
This paper studies the effects of the Green Revolution, one of the largest development projects in the late 20th Century, on individualism. We use a difference-in-differences approach to investigate how rapid technological and organizational changes in traditional agriculture reshaped cultural norms in Indonesia, where Green Revolution rollout was largely driven by centralized government interventions. Regions with greater exposure to Green Revolution policies experienced significant and persistent increases in individualism (as measured by a higher prevalence of infrequent names) decades after the end of the program. Results are not driven by pre-trends and hold across a battery of robustness checks. We further document suggestive, correlational evidence of a persistent fall in community funding for public goods, a key measure of collective action. Our findings suggest that technical change can lead to rapid and persistent changes in culture.

Optimal Monetary Policy with Confounding Information
Optimal Monetary Policy with Confounding Information
In this paper, we study optimal monetary policy in an economy where firms’ price-setting decisions are distorted by a signal-extraction problem: they cannot perfectly distinguish aggregate from idiosyncratic shocks based on noisy local information. This systematic misattribution of aggregate shocks to firm-specific factors generates an additional price response, implying that strict price stability is no longer optimal. Instead, the optimal policy fully stabilizes the output gap, which necessarily requires accommodating fluctuations in the price level. The cyclicality of the optimal price level depends on the source of firms’ incomplete information: learning from local demand signals implies a procyclical price level, whereas learning from local productivity signals yields a countercyclical one.

Signaling Vision: Knowing When to Quit
Signaling Vision: Knowing When to Quit
We study a signaling game where agents signal their type by choosing when to quit pursuing an uncertain project. High types observe news about project quality and quit when bad news arrives. Low types who do not observe any news may mimic high types by quitting continuously over a phase of time. The reputation dynamics may exhibit nonmonotonicity with respect to quitting time. Our analysis offers a unifying explanation for how and when both early and late quitting can enhance reputation and suggests novel welfare and policy implications.

Corporate Lobbying of Bureaucrats
Corporate Lobbying of Bureaucrats
Executive agencies play a pivotal role in shaping the regulatory environment by crafting rules, enforcing regulations, and overseeing government contracts—all of which can have a profound impact on businesses. For firms, this potential impact creates a clear incentive for firms to influence these agencies, particularly during the critical stages of rulemaking and enforcement. In this context, lobbying emerges as a key tool that companies use to mold the regulatory landscape to their advantage. Unlike politicians, whose decisions are often swayed by electoral cycles and campaign contributions, agency officials are not elected, serve longer terms, and are less susceptible to direct political pressures. As a result, engaging in lobbying efforts with executive agencies is both more complicated and strategically crucial for firms operating within heavily regulated industries. However, the dynamics of such lobbying remain underexplored in the literature.

How to Recover from Work Stress, According to Science
How to Recover from Work Stress, According to Science
To combat stress and burnout, employers are increasingly offering benefits like virtual mental health support, spontaneous days or even weeks off, meeting-free days, and flexible work scheduling. Despite these efforts and the increasing number of employees buying into the importance of wellness, the effort is lost if you don’t actually recover. So, if you feel like you’re burning out, what works when it comes to recovering from stress? The authors discuss the “recovery paradox” — that when our bodies and minds need to recover and reset the most, we’re the least likely and able to do something about it — and present five research-backed strategies for recovering from stress at work.

前不久,2026年8月2日,歐盟《人工智慧法》核心條款正式生效:所有AI生成內容必須清晰標註,聊天機器人必須告知用戶正在與AI互動,違規企業最高面臨1500萬歐元或全球年營業額3%的罰款。這不是一份可以選擇遵守的行業倡議,而是具有法律約束力的監管底線——AI信任,已經從企業內部的道德自覺,變成外部強制的合規要求。
