Comparing the True Cost of Living Indices of Demographically Different Households

The comparison of true cost of living indices between demographically different households (relative equivalence scale) is argued to be sensitive to the way demographic characteristics enter demand analysis. In particular, parameters reflecting the cost of demographic characteristics at base prices, though themselves do not have welfare (equivalence scale) interpretation, can alter the benchmark from which demographically varying inflation effects are measured. The empirical analysis, based on a rank‐3 demand system applied to UK individual household data, shows that the inflation adjustment of child benefits can vary with the way demographic costs at base period prices are specified.     

Macroeconomic interdependence under incomplete markets

This paper uses a two-country, flexible-price model with overlapping generations of infinitely lived households to study the role of net foreign asset dynamics in the propagation of productivity shocks. Absence of Ricardian equivalence ensures existence of a unique steady-state level of net foreign assets, to which the economy returns following temporary shocks. Model dynamics are significantly different from those of a setup in which terms of trade movements perform all the international adjustment and net foreign assets do not move. The difference relative to a complete markets economy in which net foreign asset movements play no role in shock transmission is smaller. It is amplified if the substitutability across goods rises and if shocks are permanent.     

Designs for estimating an extremal point of quadratic regression models in a hyperball

This paper is devoted to studying optimal designs for estimating an extremal point of a multivariate quadratic regression model in the unit hyperball. The problem of estimating an extremal point is reduced to that of estimating certain parameters of a corresponding nonlinear (in parameters) regression model. For this reduced problem truncated locally D-optimal designs are found in an explicit form. The result is a generalization of the results of Fedorov and Müller (1997) for onedimensional quadratic regression function in the unit segment. Received February 2002     

当前若干促进农民增收措施的效果与未来取向

当前,我国各级政府为了促进农民增收相继出台了一系列的政策措施,但这些措施实施的效果并不尽如人意.我国农民收入增长缓慢的根本原因在于农民人均可耕种面积太小,过多的农民拥挤在有限的土地上,使得很多促进农民增收的措施效果不明显.因此,解决农民增收问题,必须加快城市化步伐,把农民从土地上解放出来.

我国西部城乡一体化与东部的差距——以重庆和上海为例

根据重庆与上海的比较,西部地区城乡一体化水平落后于东部地区的最主要原因是西部地区的城市化进程远远慢于东部地区的城市化进程,城乡居民收入差异和恩格尔系数的差异也是西部地区城乡一体化程度低于东部地区的原因.因此,大幅度提高城市化水平、调整产业结构、建立城乡统一的市场等,是今后西部地区加快实现城乡一体化的几个主要切入点.     

城乡居民收入差距的动态演变:1988～2002年

中国城乡居民收入差距已经引起广泛关注。文章以住户调查数据为基础,利用泰尔指数分解、G.Fields分解、Blinder分解、分位回归分解等多种方法讨论了1988年、1995年和2002年“城乡”因素本身对城乡居民收入差距的贡献。这些分解结果表明我国的城乡差距较显著并在不断扩大;而且城乡差距更不利于农村中的低收入人群。     

The Austrian current account deficit: Driven by twin deficits or by intertemporal expenditure allocation?

The evidence presented in the paper rejects the twin deficit hypothesis for the Austrian current account balance during the last two decades. The results are based on an estimate of a vector error correction model including quarterly data for the current account balance and potentially relevant variables driving its dynamics. We compute the variance decomposition of the current account's forecast error and its generalized impulse responses to shocks in the innovations of the system. The results in favor of intertemporal expenditure reallocation cannot be reproduced within a second analysis including the current account and a measure of net output, however. The estimated implicit current account balance, interpreted as the discounted expected change in future net output, does not follow the actual behaviour of the current account.

金融发展影响城乡收入差距的三大效应及检验

金融发展影响城乡收入差距主要通过三条途径,即金融发展的门槛效应、金融发展的降低贫困效应、金融发展的非均衡效应。本文利用中国和省级1978~2004年的相关数据进行实证检验,结果显示实证与理论假说相符。最后,提出了相关政策建议。
