摘要：This paper examines the causal effect of political legitimacy on stability, using the historical case of Imperial China. Chinese rulers ascribed their legitimacy to a heavenly mandate. Calamities like earthquakes were considered to be a sign of weakened approval, making quakes a proxy for a negative legitimacy shock. I use quake-induced minor shaking (i.e., strong enough to be felt, but too weak to cause material damage) to demonstrate that legitimacy shocks cause more conflicts. I examine whe...

摘要：Trusting behaviour is a cornerstone of cooperation and, hence, economic performance, not least in poorer communities where economic transactions often rely on informal agreements. But trusting behaviour is potentially costly since the counterpart may decide to defect. In this study, we investigate whether food scarcity influences the level of trusting behaviour in rural Tanzania by leveraging quasi-experimental variation in food supply induced by the harvest. Through a lab-in-the-field experim...

摘要：I measure the economic effects of greenbelts that prohibit new construction beyond a predefined urban fringe and therefore act as urban growth boundaries. I focus on England, where $13\%$ of the land is designated as greenbelt land. I provide reduced-form evidence and estimate a quantitative equilibrium model that includes amenities, housing supply, a traffic congestion externality, agglomeration forces, productivity and household location choices. Greenbelt policy generates positive amenity e...

摘要：We use detailed data from Indonesian cities to study how variation in density within urban areas affects social capital. For identification, we instrument density with soil characteristics, and control for community averages of observed characteristics. Under plausible assumptions, these controls address sorting on observables and unobservables. We find that lower density increases trust in neighbours and community participation. We also find that lower density is associated with reduced inter...

摘要：How do changes in labour taxes affect innovation and aggregate productivity growth? To answer this question, we propose a quantitative, general equilibrium growth model featuring product and quality innovation with endogenous market structure, estimate its parameters and provide empirical validation for the propagation mechanism of labour tax changes. We find that a temporary cut in flat-rate labour taxes produces a growth acceleration in aggregate productivity, permanently increasing the path...

摘要：Using an identification strategy based on random assignment of refugees to different municipalities in Denmark between 1986 and 1998, we find strong evidence that gang crime rates in the neighbourhood at assignment increase the probability of boys to commit crimes before the age of 19, and that gang crime (but not other crime) increases the likelihood of teenage motherhood for girls. Higher levels of gang crime also have detrimental and long-lasting effects, with men experiencing significantly...

摘要：We provide new evidence on motivations for voluntary contributions to public goods in a natural setting. Using natural language processing on users' Twitter posts, we measure revealed sentiment changes before and after making a donation to Wikipedia. We find strong evidence that sentiment improves in the hour and minutes directly before contributing, which we call 'preheating'. Results are robust to alternative fixed effects and approaches to inference and supported by a complementary online e...

摘要：We study a multi-unit auction model in which bidders are privately informed about the maximum number of units they are willing to trade (which we refer to as 'capacity'). No matter how big or small, private information on capacities changes the nature of the equilibrium as compared to when private information is on costs (or valuations). Also, the uniform-price and discriminatory auctions are not revenue equivalent, in contrast to when costs are independently drawn. In particular, with indepen...

摘要：This paper analyses the effects of increasing the statutory retirement age for claiming full pension benefits on the labour force participation of middle-aged individuals and their partners. Identification relies on a difference-in-differences setting that exploits the heterogeneous increase in age eligibility for retirement caused by an unexpected pension reform. We detect a rise in the participation rate of middle-aged women that spills over into the labour supply of their husbands, who choo...

摘要：This paper analyses the impact of fiscal spending shocks in a dynamic, multi-country model with international production networks. The response of real gross domestic product to a fiscal spending shock can be decomposed into a direct effect, income effect and price effect. The direct effect depends only on input-output linkages, while the price effect is zero in the aggregate. We apply this decomposition to the Eurozone, and find that fiscal spillovers from Germany and the core Eurozone countr...
