A substantial literature examines how the Pigouvian directive that marginal taxes should equal marginal external harms needs to be modified in light of the preexisting distortion due to labor income taxation. Additional literature considers distributive concerns. It is demonstrated, however, that simple first‐best rules—unmodified for labor supply distortion or distribution—are correct in the model examined. Specifically, setting all commodity taxes equal to marginal harms (and subsidies equal to marginal benefits) can generate a Pareto improvement, as can a marginal reform toward the first‐best. Qualifications and explanations for differences from previous work are also presented.  相似文献

We propose an empirical procedure, which exploits the conditional heteroscedasticity of fundamental disturbances, to test the targeting and orthogonality restrictions imposed in the recent VAR literature to identify monetary policy shocks. Based on U.S. monthly data for the post-1982 period, we reject the non-borrowed-reserve and interest-rate targeting procedures. In contrast, we present evidence supporting targeting procedures implying more than one policy variable. We also always reject the orthogonality conditions between policy shocks and macroeconomic variables. We show that using invalid restrictions often produces misleading policy measures and dynamic responses. These results have important implications for the measurement of policy shocks and their temporal effects as well as for the estimation of the monetary authority's reaction function.  相似文献

State laws mandate the recycling of municipal solid waste (MSW) across most of the United States. In order to comply, municipalities recycle quotas of materials, generally without regard to fluctuating prices. An inventory system is proposed that allows municipalities to be sensitive to materials prices as they recycle in accordance with state mandates. A dynamic model is developed that uses historical secondary material prices as exogenous inputs to minimize the net present value of MSW recycling system cost. The model provides a cost effective method for municipalities to achieve their MSW recycling targets. The savings is approximately $1.28 per ton of MSW generated as based on total MSW management costs of $13.5 per ton. The model also allows one to investigate the effectiveness of various strategies for increasing the recycling rate, including reducing the transportation cost for recyclables, supporting the market price of selected secondary materials, and landfill bans on selected materials. Our proposed model may also be used to investigate the effect of market price changes on the portfolio of materials held in inventory for recycling.  相似文献

Abnormally high net insider selling is commonly observed after repurchase tender offer (RTO) announcements although, on average, firms experience positive abnormal returns in the years after the repurchases. We explore two potential explanations: liquidity trade timing and informed trading. Consistent with the notion that fixed price RTOs are more likely than Dutch-auction RTOs to signal undervaluation, the results suggest that insider selling after fixed price RTO announcements are driven largely by insiders who time their trades with the repurchase announcements. In contrast, selling after Dutch-auction RTOs seems to be driven primarily by informed traders who exploit mispricing associated with the repurchase announcements.  相似文献

Employing a regression discontinuity (RD) approach on gubernatorial elections in the United States over the last three decades, this paper investigates the causal effects of governors' party affiliation (Democrat versus Republican) on unionization of workers, and unionized workers' working hours and earnings. Surprisingly, we find no significant impact from the party affiliation of governors on union membership and union workers' labor‐market outcomes.  相似文献

The market structure of an industry plays an important role in determining the stock market performance of surviving firms during intra-industry bankruptcy announcements. On evaluating the announcement effects of a survivor sample from each of two industries with very different market structures, namely the airline industry and the railroad industry, we find that the airline sample received significant abnormal returns (positive ripple) while the railroad sample experienced significant abnormal losses (negative ripple). Furthermore, the differences of the abnormal returns from the two samples also are statistically significant. These findings demonstrate support for the market structure hypothesis (MSH), but cast doubt on the contagion effect hypothesis (CEH).  相似文献
