We analyse the state of the art in the field of life cycle portfolio choice, a recent strand of the literature on intertemporal
portfolio selection. Life cycle models are designed to identify optimal savings and portfolio policies over the lifetime of
investors. They can help to improve pension schemes by showing how these could be specifically tailored to the individual
employee’s circumstances to overcome the ‘one-size-fits-all’ philosophy still prevailing in parts of the mandatory retirement
savings system. To facilitate comparison, we first describe set-up, solution method and characteristic results for a basic
model and then derive a general framework to classify existing contributions. We highlight the models’ strengths and weaknesses
and assess their ability to resolve existing portfolio puzzles. Lessons from the literature are summarized and promising areas
for further research identified.

后发劣势:对后发国家发展战略的深层思考 总被引:9,自引:0,他引:9
随着国内外环境的改变和后发劣势的增加,曾经是后发国家最优战略选择的日、韩模式已失去了其存在的基础,盲目模仿反而会造成政府与市场的双重失灵;而作为当前最优制度选择的西方成熟的民主市场经济加宏观调控体制,则由于国情相异太大,后发国家难以模仿;在这种背景下,作为次优战略选择的民主宪政加自由市场模式就成为大部分后发国家当前的最佳选择. 相似文献

ABSTRACT Using firm-level labour union data from Japan, this paper investigates the effect of labour unions on firm leverage. We find that as union coverage increases, both the level of and extent of change in leverage decreases. These relations remain robust when a firm falls into deficit. We also find that firms with higher union coverage have a higher interest coverage ratio. In addition, we find that firms with higher union coverage are less likely to choose issuing debt compared to issuing equity when they face financial distress. Our results imply that significant employee influence enhanced by labour unions increases fixed costs, crowds out the firm’s debt capacity and consequently reduces the firm’s leverage. 相似文献

This paper investigates to what extent individuals' risk preferences are correlated with the cross-sectional earnings risk of their occupation. We exploit data from the German Socio-Economic Panel, which contains a direct survey question about willingness to take risks that has been shown to be a behaviorally valid measure of risk aversion. As a measure of earnings risk, we use the cross-sectional variation in earnings that is left unexplained by human capital variables in Mincerian wage regressions. Our evidence shows that individuals with low willingness to take risks are more likely to work in occupations with low earnings risk. This pattern is found regardless of the level of occupation categories, region, gender and labor market experience. 相似文献

We investigate how unit (or specific) tax and ad valorem tax affect equilibrium location choice in a model of product differentiation,
which includes Hotelling (linear-city) and Vickrey-Salop (circular-city) spatial models as special cases. We find that neither
tax affects equilibrium location patterns as long as each firm has the same production cost. Two taxes can yield different
location patterns under cost heterogeneity among firms. 相似文献

Marco Dardi 《International Review of Economics》2006,53(4):476-490
Pareto initiated the shift of economic theory from utility/preference to choice in order to fill a gap between theoretical
and empirical economics. His suggestions for an empirically-oriented theory of choice were to be developed decades later in
the literature on revealed preference and on the conditions of equivalence between preference-based and choice-based axiomatic
structures. In the process, however, substantial departures from Pareto’s implicit design of the situation of choice were
introduced. In this paper, the conditions for the rationalizability of choice are re-defined so that they fit the type of
situation that Pareto had in mind. The result is that the main consistency axioms of standard choice theory have to give way
to a different combination of axioms that concern decisiveness as well as consistency. (JEL:B13, D01, D11). 相似文献

ABSTRACTProspect theory is widely thought to be one of the best-confirmed accounts of human decision-making under risk. There are numerous claims in the literature that various kinds of nonexperimental, observational evidence provide strong support for prospect theory. We investigate the veracity of these claims using a set of philosophy of science morals and a careful delineation of models of choice under risk, focussing on the extant versions of prospect theory and their various components. We challenge the claim that prospect theory is well supported because it explains the equity premium puzzle. In addition, we analyse a major international survey thought to support prospect theory and argue that the support is questionable, both for statistical reasons and because the evidence itself is mixed. Our analyses highlight some important ideas in the philosophy of science and caution against strong claims about support for prospect theory that rely on nonexperimental, observational evidence. 相似文献
