摘要：Using rich administrative data from Norway, we evaluate a 1998 work-encouraging reform targeted at single parents. We especially focus on educational performance for the children of the involved single mothers. For these children, average school grades at age 16 dropped significantly by 0.7% of a standard deviation per additional year that their mothers were exposed to the reform. Furthermore, we find that the reform affected single mothers by increasing their working hours (and thereby reduci...

摘要：Insurers are increasingly requiring physicians to obtain prior authorization before prescribing drugs that are costly or have high abuse potential. These prior authorization requirements have the potential to reduce risky prescriptions and to lower prescription drug costs, but little is known about their ability to do either. This study estimates the effect of a prior authorization requirement for certain costly and abuse-prone drugs on prescription drug use and costs for work-related injuries...

摘要：We analyze price responses to large restaurant VAT rate reductions in two different European countries. Our results show that responses in the short and medium run were clustered around two focal points of zero pass-through and full pass-through. Differences between independent restaurants and chains is the key explanation for this pattern. While nearly all independent restaurants effectively ignored the tax reductions and left consumer prices unchanged, a substantial fraction of restaurants b...

摘要：Driving restriction programs have been implemented in many cities around the world to alleviate pollution and congestion problems. Enforcement of such programs is costly and can potentially displace policing resources used for crime prevention and crime detection. Hence, driving restrictions may increase crime. To test this hypothesis, we exploit both temporal and spatial variation in the implementation of Quito, Ecuador's Pico y Placa program, and evaluate its effect on crime. Both difference...

摘要：This paper employs an instrumental variables strategy to identify the effect of party ideology on policy outcomes. Exogenous variation in party representation is generated by the assassination of the leader of the Congress party, which occurred midway through India's national elections in 1991, and dramatically increased the probability of Congress victory for a subset of constituencies. Representation by the Congress party leads to a substantial increase in the provision of public goods favor...

摘要：When procuring multiple products from competing sellers, a buyer may choose separate purchase, pure bundling, or mixed bundling. We show that pure bundling maximizes buyer surplus when there are two sellers and trade for each good is likely efficient, whereas separate purchase can be optimal for the buyer when there are more sellers or one good has a low probability of trade. We explain how these results are related to the reduction of sellers' cost dispersion and the potential adverse tying u...

摘要：How should one use (quasi -)experimental evidence when choosing policies such as tax rates, health insurance copay, unemployment benefit levels, and class sizes in schools? This paper suggests an approach based on maximizing posterior expected social welfare, combining insights from (i) optimal policy theory as developed in the field of public finance, and (ii) machine learning using Gaussian process priors. We provide explicit formulas for posterior expected social welfare and optimal policie...

摘要：This study presents a two-period overlapping-generations model with endogenous growth. In each period, the government representing young and old generations provides a public good financed by labor income taxation and public debt issuance, and the government's policies are determined by probabilistic voting. Increased political power of the old lowers economic growth. A debt-ceiling rule is considered to resolve the negative growth effect, but it creates a trade-off between generations in term...

摘要：Cost inefficiencies in public procurement tend to come from two sources: corruption (moral hazard) and incompetence (adverse selection). In most countries, audit authorities are responsible for monitoring costs but do not distinguish both sources of inefficiency in their audits. Judicial courts typically rely on these cost audits, but only sanction corruption. In a model of public procurement by politicians, we study how the respective quality of the two courts affects corruption as well as co...

摘要：Monthly welfare programs such as the Supplemental Nutrition Assistance Program (SNAP) produce consistent cycles of expenditure and consumption among recipients. Food insecurity, health status, crime, poor behavior and test scores track these cycles. This paper leverages new data from the USDA-the FoodAPS survey-to better understand these cycles in three ways. First, I find that expenditure and consumption cycles are correlated within households-a fact not previously established. Second, I stud...
