摘要:Many programs reward or penalize schools based on students' average performance. Mean reversion is a potentially serious hindrance to the evaluation of such interventions. Chile's 900 Schools Program (P-900) allocated resources based on cutoffs in schools' mean test scores. This paper shows that transitory noise in average scores and mean reversion lead conventional estimation approaches to overstate the impacts of such programs. It further shows how a regression-discontinuity design can be us...

摘要:This paper examines hospital responses to changes in diagnosis-specific prices by exploiting a 1988 policy reform that generated large price changes for 43 percent of Medicare admissions. I find hospitals responded primarily by upcoding patients to diagnosis codes with the largest price increases. This response was particularly strong among for-profit hospitals. I find little evidence hospitals increased the volume of admissions differentially for diagnoses subject to the largest price increa...

摘要:Farley W. Grubb's recent papers on the early U.S. monetary system would be important contributions to the common currency area literature were not most Of their historical assertions questionable and their key assumption-that the medium of exchange can be inferred from the unit of account-dubious. We contend that after 1781 most Americans eschewed government paper money in favor of full-bodied coins and convertible bank liabilities and that, contrary to Grubb's claim, bankers did not foist the...

摘要:What accounts for the worldwide advance of financial reforms in the last quarter century? Using a new index of financial liberalization, we find that influential events shook the policy status quo. Balance-of-payments crises spurred reforms, but banking crises set liberalization back. Falling global interest rates strengthened reformers, while new governments went both ways. The overall trend toward liberalization, however, reflected pressures and incentives generated by initial reforms that r...

摘要:Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. We show that even were this the case, there remains a powerful argument for large-scale open market operations as a fiscal policy tool. As we also demonstrate, however, this same reasoning implies that open-market operations will be beneficial for stabilizatio...

摘要:We show that extrinsic or nonfundamental uncertainty influences markets in a controlled environment. This work provides the first direct evidence of sunspot equilibria. These equilibria require a common understanding of the semantics of the sunspot variable, and they appear to be sensitive to the flow of information. Sunspots always occur in a closed-book call market, but they happen only occasionally in a double auction, where inframarginal bids and offers are observable.
