We examine the unconditional distribution of the realized variance of three European stock market indexes obtained from intraday transaction prices. We find that they share common distributional features: a significant mass close to zero, a sharp decrease afterwards and a significant right tail. Their important differences, however, compel us to model them non-parametrically through lognormal kernel estimators. We then move to the analysis of their dependence structure and find strong evidence of asymmetry. Hence, unlike common practice, we resort to non-exchangeable copula models. Such a characterization also allows us to assess the direction of greater contamination among stock market variances. 相似文献

This paper presents Bayesian inference procedures for the continuous time mover–stayer model applied to labour market transition data collected in discrete time. These methods allow us to derive the probability of embeddability of the discrete‐time modelling with the continuous‐time one. A special emphasis is put on two alternative procedures, namely the importance sampling algorithm and a new Gibbs sampling algorithm. Transition intensities, proportions of stayers and functions of these parameters are then estimated with the Gibbs sampling algorithm for individual transition data coming from the French Labour Force Surveys collected over the period 1986–2000.

Empirical Tests for Stochastic Dominance Efficiency 总被引:4,自引:0,他引:4
Thierry PostAssociate Professor 《The Journal of Finance》2003,58(5):1905-1932
We derive empirical tests for the stochastic dominance efficiency of a given portfolio with respect to all possible portfolios constructed from a set of assets. The tests can be computed using straightforward linear programming. Bootstrapping techniques and asymptotic distribution theory can approximate the sampling properties of the test results and allow for statistical inference. Our results could provide a stimulus to the further proliferation of stochastic dominance for the problem of portfolio selection and evaluation. Using our tests, the Fama and French market portfolio is significantly inefficient relative to benchmark portfolios formed on market capitalization and book‐to‐market equity ratio. 相似文献

Academic literature in public finance has focused on interjurisdictional tax competition—namely among similar types of local governments—but has leaved vertical externalities arising from interactions between two overlapping governments sharing the same tax base aside. The purpose of this paper is to provide a simple model within which interjurisdictional tax competition and vertical interactions between two overlapping governments that share the same tax base can be analyzed simultaneously. We find that interjurisdictional tax competition reduces the global tax rate set by both overlapping governments (federal and local) but is unable to solve completely the distortion arising from vertical externalities. The model is also extended to allow for government subsidies to industrial capital. We give sufficient conditions for capital subsidies to be more efficient to attract capital when they are granted at a federal level rather than at a local level. 相似文献

Does Risk Seeking Drive Stock Prices? A Stochastic Dominance Analysis of Aggregate Investor Preferences and Beliefs 总被引:2,自引:0,他引:2
We use various stochastic dominance criteria that account for(local) risk seeking to analyze market portfolio efficiencyrelative to benchmark portfolios formed on market capitalization,book-to-market equity ratio and price momentum. Our resultssuggest that reverse S-shaped utility functions with risk aversionfor losses and risk seeking for gains can explain stock returns.The results are also consistent with a reverse S-shaped patternof subjective probability transformation. The low average yieldon big caps, growth stocks, and past losers may reflect investorstwin desire for downside protection in bear markets and upsidepotential in bull markets. 相似文献

An impressive body of the literature has investigated the patterns of changes in implied volatilities across strike prices
and maturities. Although such studies try to explain the existence of the volatility skew and term structure, they remain
silent about the evolution of the volatility surface as time goes by and market variables move. Relying on a technique of
signal processing called Independent Component Analysis, we extract volatility modes that account for most of the variations
in the shape of the surface. We then relate the magnitude of volatility changes along those modes to market activity. 相似文献

We provide a model of product-based cultural change where trade integration leads to cultural convergence. A standard trade model of Dixit–Stiglitz monopolistic competition is coupled with a micro-founded model of cultural dynamics. We show that access to varieties that are attached to a global cultural type changes the incentives of parents to socialize their children and transmit their type. The resulting increase in agents of the global cultural type leads to a magnification of the initial shock. A striking feature of the model is that even temporary shocks to openness may have permanent effects through the changing distribution of preferences in the economy. 相似文献

Limit Order Book as a Market for Liquidity 总被引:7,自引:0,他引:7
We develop a dynamic model of a limit order market populatedby strategic liquidity traders of varying impatience. In equilibrium,patient traders tend to submit limit orders, whereas impatienttraders submit market orders. Two variables are the key determinantsof the limit order book dynamics in equilibrium: the proportionof patient traders and the order arrival rate. We offer severaltestable implications for various market quality measures suchas spread, trading frequency, market resiliency, and time toexecution for limit orders. Finally, we show the effect of imposinga minimal price variation on these measures. 相似文献

In this paper an economic model of the firm's behaviour is presented, examining the interrelationship between prevention activities and employment level. A competitive firm with a fixed capital stock is considered. Two decisions must be made: the level of employment of homogeneous workers (L) and the level of prevention activities (I). Although many simplifying assumptions are adopted, the impact of wage rate and compensation level on both decision variables is sign ambiguous. Moreover the case where injured workers are irreplaceable is more difficult than its counterpart with perfect substitutability. 相似文献

This article aims at investigating how quantitative and qualitative (indirect) network effects impact pricing and trading decisions on a Business‐to‐Business marketplace. Using an original data set collected on MFG.com, one of the most prominent B2B platforms in the U.S.A., we find that the market share of a marketplace depends on both the quantity and quality of suppliers, but that quality effects tend to substitute for quantity effects as the size of the marketplace increases. These results suggest that while the quantity of suppliers on board is crucial during the early stage of a marketplace, supplier quality matters much more in the mature stage.
