Working at home benefits entrepreneurs by lowering fixed costs and allowing them to engage in joint market and household production. We evaluate a large-scale reform in Singapore, the Home Office Scheme, that allowed business creation at one’s residential property and study whether home-based entrepreneurship spurs entrepreneurial activities. The difference-in-differences estimate shows that the reform led to a significantly higher level of business creation and the firms newly created in response to the reform had a higher survival rate. The effect is more pronounced for low-income female individuals and industries with high start-up capital, implying that financial constraints and nonpecuniary benefits likely drive the effect. The reform also encourages entrepreneurs to become serial entrepreneurs, and they open a larger business with a similar survival rate for their second firm. Overall, our findings suggest that the program effectively attracted more entry into self-employment without significantly lowering the average quality of the pool.

This study utilizes the administrative data of an innovation grant program in a major emerging economy to study which firms are best positioned to capture the state and access resources beyond what their rule-complying merits command. We trace the grant allocation process and directly observe occurrences of rule-violating funding. We show that firms vary in capability to secure irregular awards, depending on factors such as geographic proximity and the social and bureaucratic setting within which entrepreneurs and officials interact. Furthermore, by comparing the actual allocation of irregular awards with the counterfactual scenario in which recipients were evaluated solely based on grant rules, we conclude that crony capitalism, rather than bureaucratic heroism, is the primary driver of irregular awards. Governments often use innovation grant programs to promote firm innovation, but these programs sometimes fail to achieve their objectives due to grant officials violating policy rules to provide resources to undeserving firms. We study a public funding program in a major emerging economy to analyze the bureaucratic structure and the social dynamics within which entrepreneurs and bureaucrats interact to identify the sources of state-resource misallocation. We find that geographic distance, intragovernmental checks and balances, and the lack of direct social intermediary connecting entrepreneurs with bureaucrats help reduce the likelihood of collusion for state-resource misallocation. Our results generate insights to help guide the (re)design of public funding programs, particularly in countries with low levels of transparency and public accountability.

We compile a novel data set on mandatory environmental, social, and governance (ESG) disclosure around the world to analyze the stock liquidity effects of such disclosure mandates. We document a positive effect of ESG disclosure mandates on firm-level stock liquidity. The effects are strongest if the disclosure requirements are implemented by government institutions, not on a comply-or-explain basis, and coupled with strong enforcement by informal institutions. Firms with weaker information environments benefit more from ESG disclosure mandates. Our results support the view that ESG disclosure regulation improves the information environment and has beneficial capital market effects.

This paper studies whether firms opportunistically make proprietary claims in mandatory environmental disclosure programs with trade secret exemption rules. Examining the mandatory chemical disclosure program in the fracking industry, I find evidence of opportunistic withholding of information among operators that are less likely to have trade secrets. Specifically, I find that these operators claim fewer chemicals as trade secrets when the operating site is in close proximity to water quality monitors. This is only observed among publicly traded operators that face a higher cost of societal backlash when disclosing pollutant information. Further analyses suggest that these operators are concerned about external environmental monitoring, which deters them from opportunistic information withholding. Regarding public and private operators that are more likely to have trade secrets, I do not find strong evidence that their information withholding varies with the monitoring conditions.

This paper incorporates ambiguity and information processing constraints into the He and Krishnamurthy (2012) model of intermediary asset pricing. Financial intermediaries possess greater information processing capacity than households. In response, households optimally choose to delegate their investment decisions. The contractual relationship between households and intermediaries is subject to a moral hazard friction, which results in a financial constraint. We show that ambiguity aversion not only amplifies households' incentives to delegate but also tightens the financial constraint. The calibrated model can quantitatively explain both the unconditional and time-varying moments of observed asset prices while endogenously generating an empirically consistent crisis frequency.

This paper studies how social media affects the dynamics of protests and strikes in China during 2009–2017. Based on 13.2 billion microblog posts, we use tweets and retweets to measure social media communication across cities and exploit its rapid expansion for identification. We find that, despite strict government censorship, Chinese social media has a sizeable effect on the geographical spread of protests and strikes. Furthermore, social media communication considerably expands the scope of protests by spreading events across different causes (e.g., from anticorruption protests to environmental protests) and dramatically increases the probability of far‐reaching protest waves with simultaneous events occurring in many cities. These effects arise even though Chinese social media barely circulates content that explicitly helps organize protests.

We present a tractable model that accommodates asset-market sentiment in a standard Dynamic Stochastic General Equilibrium (DSGE) setting, allowing us to quantitatively evaluate sentiment-driven macroeconomic fluctuations. In our model, changes in households' perceived uncertainty about housing prices lead to self-fulfilling fluctuations in housing prices, which then impact investment and output through entrepreneurs' collateral constraints. Household sentiment shocks hence are transmitted and propagated to the macroeconomy, generating boom–bust cycles. Uncertainty, housing prices, and the real economy are linked. Quantitatively, the sentiment shock in the form of risk–panic is a crucial driver of business cycle fluctuations despite the presence of various competing shocks.

Online video platforms face the challenge of balancing the needs of their users with those of their advertisers. Although users typically prefer to have less intrusive ads, advertisers aim to effectively catch user attention. This paper investigates how the provision of ad choice affects the effectiveness of video advertising. We argue that allowing users to choose an ad to view may trigger a “conjecture-formation-and-confirmation” process that motivates users to pay more attention to the selected ad. Two online experiments and four laboratory experiments are conducted to test the theorized underlying mechanism of the ad choice effect. Study 1 finds when users are unfamiliar (versus familiar) with the content of ad options (i.e., they need to make conjectures about ad content), ad choice is more likely to increase user attention to the chosen ad. Study 2 and Study 3 show that the impact of ad choice on user attention is more likely to be positive when users are enabled to make conjectures about ad content, such as when choice options provide more relevant information about ad content. Study 4a and Study 4b provide more direct support for the underlying mechanism by showing that the ad choice effect is attenuated when users cannot form conjectures about ad content at the choice stage. Study 5 further demonstrates that the positive effect of ad choice is robust across different ad settings. Taken together, these studies show ad choice is more likely to boost the effectiveness of video advertising when the “conjecture-formation-and-confirmation” process is triggered.

Innovative firms must trade off disclosing to investors and maintaining secrecy from competitors. We study this trade-off in a sample of IP licenses mandatorily disclosed by US public firms, whose contents can be temporarily redacted. Hand classifying the redacted information, we find that firms with valuable IP in competitive markets redact IP information more often. Markets react positively to the redaction of IP information, consistent with theoretical predictions rationalizing a separating equilibrium in which nondisclosure signals more valuable IP. Our results suggest that credible nondisclosure partially resolves information frictions for innovative public firms when facilitated by sophisticated investors.
