Volatility of capital flows and financial liberalization: Do specific flows respond differently? 总被引:2,自引:0,他引:2
Rebecca M. Neumann Ron Penl Altin Tanku 《International Review of Economics & Finance》2009,18(3):488-501
This paper examines the volatility of capital flows following the liberalization of financial markets. Utilizing a panel data set of overlapping data, the paper focuses on the response of foreign direct investment, portfolio flows, and other debt flows to financial liberalization. The financial liberalization variable comes from the chronology and index developed by Kaminsky and Schmukler [Kaminsky, G.L. and Schmukler, S.L., 2003, Short-run pain, long-run gain: The effects of financial liberalization, IMF Working Paper WP/03/34.]. Different types of capital flows are found to respond differently to financial liberalization. Surprisingly, portfolio flows appear to show little response to capital liberalization while foreign direct investment flows show significant increases in volatility, particularly for the emerging markets considered. 相似文献

When panel data are not available, retrospective data are used in the estimation of dynamic choice models. However, retrospective data are not reliable. Previous studies of voting choices, for example, have shown that respondents misreport their past choices in order to appear more consistent with their current choice. Such retrospective bias leads to inconsistent estimates, especially when there is state dependence in choices. Specifically, observed persistence in retrospective data may be due to (a) true state dependence, (b) unobserved heterogeneity, and (c) retrospective bias in reporting previous choices. Whereas Heckman in his 1981 study deals with (a) and (b), we introduce a method to estimate true state dependence while accounting for both unobserved heterogeneity and retrospective reporting bias. Our method is based on modeling the reporting behavior and integrating it into the estimation. The identification strategy is based on the correlation between the reported previous choices and current exogenous variables. Using data on Israeli voters, we find that the probability that a respondent whose vote intention in 1991 differed from his or her past voting choices would lie about their past choices is 0.23.

This paper develops an estimator that under the standard assumption of the General Linear Model, including normality of disturbances, can be designed to dominate the Restricted Least Squares estimator in quadratic risk under very general conditions. The domination is achieved for any choice of symmetric positive definite weighting matrix used in defining the quadratic risk function, regardless of the correctness of the constraints used to define the restricted least squares estimator. The general problem conditions under which the estimator exists, and the risk behavior of the estimator over the parameter space are identified. 相似文献

We study the consumption-portfolio problem in a setting with capital gain taxes and multiple risky stocks to understand how short selling influences portfolio choice with a shorting-the-box restriction. Our analysis uncovers a novel trading flexibility strategy whereby, to minimize future tax-induced trading costs, the investor optimally shorts one of the stocks (or equivalently, buys put options) even when no stock has an embedded gain. Alternatively, an imperfect form of shorting the box can reduce aggregate equity exposure ex post. Given these two short selling strategies, it is common for an unconstrained investor to short some equity while a constrained investor holds a positive investment in all stocks. With no shorting, the benefit of trading separately in multiple stocks is not economically significant. 相似文献

This study examines farmers' and experts' perceptions of important action points for improving food safety on the dairy farm. Adaptive conjoint analysis is used to elicit these perceptions. A comparison on the basis of professional background (farmers versus experts) shows no major differences in the perceptions regarding chemical and microbiological hazards. Two-stage cluster analysis of individual perceptions regarding chemical and microbiological hazards results in four and three distinct groups, respectively. Although results indicate a rather good level of farmers' knowledge of most important action points, the findings can be used to modify current education programs aimed at improving farm-level food safety. 相似文献

This paper reports the results of an investigation into the impact of the revaluation of fixed assets on the reported results of NHS ambulance services. It recalculates the accounting rate of return of individual trusts after removing revaluation adjustments and examines the published responses of trusts. The numerical analysis demonstrates that, in general, revaluation has depressed the stated rate of return in an inconsistent manner. Failure to meet the required rate of return may cause a trust to be subjected to additional monitoring and management reorganisation while the trusts respond by explaining deviations in the accounting return measure by referring to revaluations and other technical adjustments. Management decisions made in response to these accounting measures may be sub-optimal in delivering health care but appropriate in achieving the desired accounting outcome. 相似文献

Do firms understate stock option-based compensation expense disclosed under SFAS 123? 总被引:1,自引:0,他引:1
Focusing on the four key option pricing model inputs—expected option life, expected stock price volatility, expected dividend yield, and the risk-free interest rate for the expected life of the option—this study finds that firms understate option value estimates and, thus, stock-based compensation expense disclosed under SFAS 123. As predicted based on incentives and opportunities for management to understate SFAS 123 expense, the understatement of option value estimates is increasing in proxies for the magnitude of the expense, is greater for firms with weaker corporate governance, and, to a lesser extent, is increasing in the excessiveness of executive pay. The findings are strongest for the expected option life and expected stock price volatility input assumptions, consistent with firms’ greater latitude in determining these inputs. We find weaker evidence of understatement associated with the expected dividend yield assumption, and none for the interest rate assumption, consistent with these inputs being less amenable to discretion. Taken together, our findings raise some concern that the exercise of management discretion adversely affects the overall reliability of SFAS 123 expense.

Papua New Guinea (PNG) has much to learn from the Indonesian economic experience of coping with one booming sector while creating an environment in which the economy could generate jobs. PNG's macroeconomic policy adjustments to the boom-bust cycles which characterise its economy work extremely well by comparison to most other developing countries experiencing the same difficulties. At the microeconomic level, policy improvement has been harder, with the rhetoric far out-distancing the actual advances. The challenge is to improve the productivity of the agricultural sector, to raise the education levels, and to attract investment to provide employment. At present the investment environment is bleak because of the deteriorating law and order situation. 相似文献
