We use techniques developed to analyze the Supply Curve in liquidity models in order to analyze the accuracy of the Lee and
Ready algorithm, both for highly liquid and relatively liquid stocks. Through the use of order book data combined with tick
data, we are actually (somewhat tediously) able to tell whether or not a given trade is buyer or seller initiated. For those
trades where such knowledge is certain, the accuracy of the Lee and Ready algorithm is not as accurate as has been assumed
previously. We can essentially prove that the Lee and Ready algorithm is always at least 55% accurate, and is around 61% accurate
for highly liquid stocks (i.e., the top 50 of the S&P 100). 相似文献

We study the welfare effect of tax-optimizing portfolio decisions in a life cycle model with unspanned labor income and realization-based capital gain taxation. For realistic parameterizations of our model, certainty equivalent welfare gains from fully tax-optimized portfolio decisions are less than 2% of present financial wealth and lifetime income compared to a heuristic portfolio policy ignoring the taxation of profits (capital gains, interest and dividend payments). Compared to a heuristic portfolio policy that only ignores the realization-based feature of capital gain taxation and instead assumes mark-to-market taxation, these gains are less than 0.5%. That is, our work provides a justification for ignoring taxes in life cycle portfolio choice problems – a wide-spread assumption in that literature. However, if capital gains are forgiven at death (as in the U.S.), investors with strong bequest motives face substantial welfare costs when not tax-optimizing their portfolio decisions towards the end of the life cycle. 相似文献

This study has three main objectives. First, it develops a generalization of the commonly used EKS method to multilateral price comparisons. It is shown that the EKS system can be generalized so that weights can be attached to each of the link comparisons used in the EKS computations. These weights can account for differing levels of reliability of the underlying binary comparisons. Second, various reliability measures and corresponding weighting schemes are presented and their merits discussed. Finally, these new methods are applied to an international data set of manufacturing prices from the ICOP project. Although theoretically superior, it appears that the empirical impact of the weighted EKS method is generally small compared to the unweighted EKS. It is also found that this impact is larger when it is applied at lower levels of aggregation. Finally, the importance of using sector specific PPPs in assessing relative levels of manufacturing productivity is indicated. 相似文献

Prior competitive dynamics research has drawn on theories of information processing to model the subjective antecedents of executives' retaliation choices. This prior work has made great progress in developing our understanding of the retaliation choices most firms will make to a given type of attack. What the information processing perspective has not been able to do is explain firm‐specific behavior to predict which competitive moves individual firms will challenge, or explain why individual firms differ in the types of actions that they are most likely to challenge. The goal of this paper is to sharpen the theoretical and empirical focus on predicting firm‐level retaliation proclivities. We leverage managerial cognition research to examine the relationship between firm‐level differences in the cognitive frameworks that executives possess, and firm‐level differences in whether and how quickly firms challenge a market move. Results from a longitudinal study of the airline industry suggest that the addition of a cognitive perspective provides important insights into competitive retaliation.

We analytically solve the portfolio choice problem in the presence of wash sale constraints in a two-period model with one risky asset. Our results show that wash sale constraints can heavily affect portfolio choice of investors with unrealized losses. The trading behavior of such investors is to a large extent driven by the desire to realize those losses, either immediately by sharply decreasing the holding of assets carrying unrealized losses, or indirectly by increasing such holdings in order to prepare for a decrease in a future period to earn the tax rebate payment. Our findings are robust to increasing the number of trading dates and introducing a second risky asset and a correlation structure. 相似文献

Credit Constraints in Manufacturing Enterprises in Africa 总被引:2,自引:0,他引:2

We investigate the question of whether firms in Africa's manufacturingsector are credit constrained. The fact that few firms obtaincredit is not sufficient to prove constraints, since certainfirms may not have a demand for credit while others may be refusedcredit as part of profit maximising behaviour by banks. To investigatethis question, we use direct evidence on whether firms had ademand of credit and whether their demand was satisfied in theformal credit market, based on panel data on firms in the manufacturingsector from six African countries. Of those firms with a demandfor credit, only a quarter obtained a formal sector loan. Ouranalysis suggests that while banks allocate credit on the basisof expected profits, micro or small firms are much less likelyto get a loan than large firms. We also find that outstandingdebt is positively related with obtaining further lending. Therole of outstanding debt is likely to be a reflection of inefficiencyin credit markets, while the fact that size matters is consistentwith a bias as well, although we cannot totally exclude thatthey reflect transactions costs on the part of banks. We presentan analysis showing how much more profitable small firms mustbe to obtain a loan than large firms. 相似文献

The Link between Institutional and Economic Integration: Insights for Latin America from the European Experience 总被引:1,自引:1,他引:0

The European experience illustrates that institutional integration interacts with economic integration at the regional level. In this paper we ask how economic and institutional integration are linked and whether there is a causal link between the two. We present an original indicator of institutional integration and study how it developed vis-à-vis diverse measures of economic integration. In particular, we ask what insights can be drawn from the European process of regional integration, which started in the 1950s, for regional integration in Latin America today. We find that Latin America is currently less economically integrated not only than the European Union today, but for certain economic variables even than the European Union in the 1960s. A VAR analysis illustrates that the link between institutional and economic integration has worked both ways throughout the European experience. There is also evidence that stronger institutional integration has indeed led to deeper economic integration. 相似文献

We examine the portfolio choice problem of an investor with constant relative risk aversion in a financial market with partially hedgeable interest rate risk. The individual shadow price of the portfolio constraint is characterized as the solution of a new backward equation involving Malliavin derivatives. A generalization of this equation is studied and solved in explicit form. This result, applied to our financial model, yields closed-form solutions for the shadow price and the optimal portfolio. The effects of parameters such as risk aversion, interest rate volatility, investment horizon, and tightness of the constraint are examined. Applications of our method to a monetary economy with inflation risk and to an international setting with currency risk are also provided. 相似文献
