摘要：I examine the source and welfare implications of differences in household consumption diversity. I document the existence of a positive correlation between household variety and expenditure to motivate a simple framework where households purchase more varieties to counteract diminishing returns to quantity but face location-specific costs of accessing variety. Estimating the model with Indian household data, I find that the increase in dietary diversity between 1983 and 2009 was mostly due to ...

摘要：In this paper, we analyze the effect of light conditions on road accidents and estimate the long-run consequences of different time regimes for road safety. Identification is based on variation in light conditions induced by differences in sunrise and sunset times across space and time. We estimate that darkness causes annual costs of more than 500 pound million in Great Britain. By setting daylight saving time year-round, 8% of these costs could be saved. Thus, focusing solely on the short-ru...

We derive conditions under which politicians flip-flop, voting according to their policy preferences at the beginning of their terms but in line with the preferences of single-issue minorities as they approach reelection. To assess the eviden...

摘要：Using administrative tax records for U.K. businesses, we document both bunching in annual turnover below the VAT registration threshold and persistent voluntary registration by almost half of the firms below the threshold. We develop a conceptual framework that can simultaneously explain these two apparently conflicting facts. The framework also predicts that higher intermediate input shares, lower product-market competition, and a lower share of business to consumer sales lead to voluntary re...
