Bayesian MCMC Mapping of Quantitative Trait Loci in a Half-sib Design: a Graphical Model Perspective
N.A. Sheehan B. Gulbrandtsen M.S. Lund D.A. Sorensen 《Revue internationale de statistique》2002,70(2):241-267
Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example. 相似文献

The aim of this paper is to provide a connection between concentration and inequality. In particular, we show that the general
entropy inequality indices are, among inequality measures, those consistent with the whole set of Hannah-Kay concentration
indices. We isolate the inequality component underlying concentration measures, obtaining an explicit additive decomposition
of the change in concentration into the change in its two components, i.e., inequality and the number of firms. This relationship
proves to be valid for the whole set of Hannah-Kay concentration indices, and embodies as particular cases some others previously
found in the literature.
We are particularly grateful to Emilio Cerdá for helpful comments on the mathematical formulation of the paper. The second

This study addresses changes in the wage structure in Finland between 1977 and 1995, and provides a simple explanation based on the demand for and supply of skills. The single index model of Card and Lemieux (1996) is augmented by incorporating changes in the supply of skills. The augmented model adequately accounts for the changes in relative wages between groups of different education and experience, but does not capture the changes in the within-group distribution.

We investigate the investment decisions of Italian state-owned enterprises (SOEs) across budget constraint regimes and carry out a natural experiment that exploits a regime switch in 1987. Drawing on the theory of capital market imperfections, we apply an empirical framework for investment analysis to a panel of manufacturing SOEs in competitive industries. We identify parallels between SOEs and widely held, quoted companies afflicted by agency problems, managerial discretion, and overinvestment. We argue that, in the case of SOEs, the soft budget regime increases managerial discretion, facilitates collusion with vote-seeking politicians, and results in wasteful investment. Consistent with our predictions, we find that the regime switch disciplines SOE's investment behavior. Following a hardening of the budget constraint, managers lose discretion to indulge in collusion and overinvestment. J. Comp. Econ., June 2002 30(4), pp. 787–811.

目前,合作金融在中国遇到了种种困惑,这不是合作金融本身的错。一方面中国从来就没有建立过真正的合作金融;另一方面合作金融与中国当前的经济环境也不相适应。而那种异化了的合作金融既没有存在的必要,也没有存在的可能。股份制取代合作制是一种历史的必然。 相似文献

This paper investigates public and private choices between internationally applicable and country‐specific education when graduates are mobile. Human capital depends on innate skills and study effort with either type of education. It is shown that national governments provide too few students with internationally applicable education, and too many with country‐specific education. This effect is mitigated, but not entirely eliminated, by the introduction of a graduate tax, according to which graduates are required to pay part of their taxes to the country where they received their education, regardless of residence. However, private educational choices are socially optimal with suitably differentiated tuition fees. 相似文献

We analyze the importance of firm-specific and country-specific factors in the leverage choice of firms from 42 countries around the world. Our analysis yields two new results. First, we find that firm-specific determinants of leverage differ across countries, while prior studies implicitly assume equal impact of these determinants. Second, although we concur with the conventional direct impact of country-specific factors on the capital structure of firms, we show that there is an indirect impact because country-specific factors also influence the roles of firm-specific determinants of leverage. 相似文献

This paper analyses the intraday lead-lag relationships between returns and volatilities in the Ibex 35 spot and futures
markets. Using hourly data, we jointly analyze the interactions between markets, estimating a bivariate error correction model
with GARCH perturbations which captures stochastically the presence of an intraday U-shaped curve for both spot and futures market volatility. Our findings show a bidirectional causal relationship between market
volatilities, with a positive feedback. This two-way transmission of volatility is consistent with market prices evolving
according to a long-run equilibrium relationship, and shocks affecting both markets in the same direction. Our empirical results
also support a unidirectional cross interaction from futures to spot market returns. This pattern suggests that the futures
market leads the spot market in order to incorporate the arrival of new information. 相似文献

This paper examines the effects of government deficits, public investment, and public capital on welfare in the transition to an aging Japan by applying a simulated general equilibrium growth model. One of the main results of this paper is that targeting only high economic growth would mislead us as to economic policies, and that a policy to reduce future government deficits is most preferable for almost all generations, even though a cut in future deficits must be followed by a decrease in public investment, thus a decrease in public capital in the future.
