We examine whether there is common behavior in limit order cancellation activity, that is, commonality in cancellation activity, on U.S. exchanges. We then examine whether this commonality in cancellation activity is associated with increased levels of return comovement and commonality in liquidity. We document strong evidence of limit order traders exhibiting exchange, industry, marketwide, and stock-level commonality with regard to cancellation activity, which is consistent with limit order traders exhibiting correlated trading behavior. We also find that this correlated behavior in cancellation activity is associated with increased levels of return comovement and commonality in liquidity. 相似文献

Arrangements for achieving efficient risk-sharing vary depending on the information available to agents in the economy. The usual Euler equation restricts efficient allocations in an economy which obeys the permanent income hypothesis, while efficient allocations in an economy with private information and long-term contracts satisfy a symmetric restriction, but not the Euler equation. Full insurance arrangements are unique in that they satisfy both restrictions.
We look at an environment in which it seems likely that long-term contracts play a role in mitigating the effects of private information: three village economies in South India. The evidence that consumption allocations satisfy the private information restriction is quite strong for households in two of the three villages; the evidence for the third village suggests that while consumption for some households satisfies the private information restrictions, other households' consumption obey the permanent income hypothesis. 相似文献

We study the profitability of traders in two fully electronic and highly liquid markets: the Dow and Standard & Poor?s 500 e-mini futures markets. Using unique information that identify counterparties to a transaction, we show and seek to explain the fact that the network pattern of trades captures the relations between behavior in the market and returns. Our approach includes a simple representation of how much a shock is amplified by the network and how widely it is transmitted. This representation provides a possible shorthand for understanding the consequences of a fat-finger trade, a withdrawing of liquidity, or other market shock. 相似文献

We compare two theoretical perspectives on the knowledge situation of headquarters (HQ) in multinational corporations: the bounded rationality perspective and the sheer ignorance perspective. We claim that these perspectives lead to different expectations when it comes to HQ's role and the effects of HQ involvement in innovation processes at the subsidiary level. More specifically, we examine the impact of HQ involvement on the efficiency of 71 subsidiary innovation projects. The findings show that HQ involvement in innovation development and transfer has a negative rather than a positive impact on efficiency in both processes. We contribute by showing and suggesting that the sheer ignorance perspective might provide a more accurate portrayal of the HQ knowledge situation than the bounded rationality perspective does. This study furthers understanding of the role of HQ in the contemporary, knowledge-creating multinational. 相似文献

Informal Insurance Arrangements with Limited Commitment: Theory and Evidence from Village Economies 总被引:2,自引:0,他引:2
Recent work on consumption allocations in village economies finds that idiosyncratic variation in consumption is systematically related to idiosyncratic variation in income, thus rejecting the hypothesis of full risk-pooling. We attempt to explain these observations by adding limited commitment as an impediment to risk-pooling. We provide a general dynamic model and completely characterise efficient informal insurance arrangements constrained by limited commitment, and test the model using data from three Indian villages. We find that the model can fully explain the dynamic response of consumption to income, but that it fails to explain the distribution of consumption across households. 相似文献

City-Pairs Versus Airport-Pairs: A Market-Definition Methodology for the Airline Industry 总被引:1,自引:0,他引:1
This paper provides a methodology for deciding which airports warrant grouping in multi-airport metropolitan areas. The methodology is based on the comparability of incremental competition effects from nearby airports on average fares at a metropolitan area’s primary airport. Results from a quarterly panel data set for the period 2003–2009 provide strong evidence that city-pairs, rather than airport-pairs, are the appropriate market definition for analyses of passenger air transportation involving many (but not all) large metropolitan areas. Based on the proposed method, we offer a recommended list of airports that should be grouped when creating city-pairs for the analysis of competition in the US domestic airline industry. 相似文献

Health insurance markets face continued challenges with high premiums and limited insurer competition. We describe a unique set of “active purchasing” policies used by Massachusetts' pioneer health insurance exchange to shape the rules of competition and reward lower-price insurers with additional customers. We provide evidence that these policies significantly influenced insurer pricing. Between 2010 and 2013, over 80% of insurer prices were set exactly at or within 1% of pricing thresholds created by active purchasing policies. A key “limited choice” policy was associated with a 16%–20% reduction in average insurance prices relative to comparison markets in 2012–2014. Insurers achieved these price cuts partly through cost reductions via narrower provider networks and partly through reduced profit margins. 相似文献
