摘要：Short-time work (STW) policies provide subsidies for hour reductions to workers in firms experiencing temporary shocks. They are the main policy tool used to support labour hoarding during downturns and were aggressively used during the coronavirus disease 2019 (COVID-19) pandemic. Yet, very little is known about their employment and welfare consequences. This article leverages unique administrative social security data from Italy and quasi-experimental variation in STW policy rules to offer e...

摘要：Entrepreneurs and venture capitalists are concerned about investors' beliefs in asset markets because these beliefs shape the value of a potential IPO and the possibility to expand. Investors' beliefs, on the other hand, can be influenced by start-up activity insofar as the latter contains valuable information about eventual profitability. This two-way feedback is shown to generate excessive, non-fundamental, waves in start-up activity, IPOs, and asset prices. Policies that lean against the wi...

摘要：A widely held view is that small firms in developing countries are prevented from making profitable investments by lack of access to credit and insurance markets. One solution is to provide repayment flexibility in credit contracts. Repayment flexibility eases both the credit constraint, as it allows for increased spending during the start-up phase, and offers insurance, in case of fluctuations in income. In a field experiment among traditional microfinance clients and larger collateralized bo...

摘要：The strategic importance of commitment in bargaining is widely acknowledged. Yet disentangling its role from key features of canonical models, such as proposal power and reputational concerns, is difficult. This paper introduces a model of bargaining with strategic commitment at its core. Following Schelling (1956, The American Economic Review, vol. 46, 281-306), commitment ability stems from the costly nature of concession and is endogenously determined by players' demands. Agreement is immed...

摘要：Growth has fallen in the U.S. amid a rise in firm concentration. Market share has shifted to low labour share firms, while within-firm labour shares have actually risen. We propose a theory linking these trends in which the driving force is falling overhead costs of spanning multiple products or a rising efficiency advantage of large firms. In response, the most efficient firms (with higher markups) spread into new product lines, thereby increasing concentration and generating a temporary burs...

摘要：We develop a new approach for estimating average treatment effects in observational studies with unobserved group-level heterogeneity. We consider a general model with group-level unconfoundedness and provide conditions under which aggregate balancing statistics-group-level averages of functions of treatments and covariates-are sufficient to eliminate differences between groups. Building on these results, we re-interpret commonly used linear fixed-effect regression estimators by writing them i...

摘要：We use textual analysis of earnings conference calls held by listed firms around the world to measure the amount of risk managers and investors at each firm associated with each country at each point in time. Flexibly aggregating this firm-country-quarter-level data allows us to systematically identify spikes in perceived country risk (crises) and document their source and pattern of transmission to foreign firms. While this pattern usually follows a gravity structure, it often changes dramati...

摘要：We introduce a portfolio friction in a two-country DSGE model where investors face a constant probability to make new portfolio decisions. The friction leads to a more gradual portfolio adjustment to shocks and a weaker portfolio response to changes in expected excess returns. We apply the model to monthly data for the US and the rest of the world for equity portfolios. We show that the model is consistent with a broad set of evidence related to portfolios, equity prices, and excess returns fo...
