This paper considers a one-sector economic growth model with several infinitely-lived heterogeneous households, who differ both in the discount factors as well as preferences over consumption. Unlike the extreme form of borrowing constraint observed in the classical Ramsey model, recently surveyed in Becker (2006), we allow limited borrowing by the households and prove the existence of a perfect foresight equilibrium. We also show that irrespective of production technology employed by the firms, the capital stock sequence converges to the steady state stock and from some time onward all impatient households are in the maximum borrowing state, whereas the most patient household owns entire capital stock and the debts of all other households. 相似文献

本文从公平性的视角对中国房产税的免征额进行实证模拟研究,旨在通过数理模型揭示免征额与公平的关系,丰富与发展房产税税制理论和公平理论,并为中国的房地产税扩围提供免征额方面的政策制定参考。基于基尼系数构建一个简化的理论模型得知,当税率大于某个值时,必存在一个可以使得税后基尼系数最小的免征额,本文将这个免征额定义为最优免征额。根据中国家庭金融调查2011年的数据测算得出,在超过1%的税率下,设置每户40平方米左右的免征额可以使得税后收入的基尼系数最小,从而实现公平效应的最大化;而如果税率超过1%,户均免征面积不能超过150平方米,否则房产税将会扩大收入差距。 相似文献

This paper describes a method to solve models with a continuum of agents, incomplete markets and aggregate uncertainty. I use backward induction on a finite grid of points in the aggregate state space. The aggregate state includes a small number of statistics (moments) of the cross-sectional distribution of capital. For any given set of moments, agents use a specific cross-sectional distribution, called “proxy distribution”, to compute the equilibrium. Information from the steady state distribution as well as from simulations can be used to chose a suitable proxy distribution. 相似文献

It is well known that central bank policies affect not only macroeconomic aggregates, but also their distribution across economic agents. Similarly, a number of papers demonstrated that heterogeneity of agents may matter for the transmission of monetary policy to macro variables. Despite this, the mainstream monetary economics literature has so far been dominated by dynamic stochastic general equilibrium models with representative agents. This paper aims to tilt this imbalance towards heterogeneous agents setups by surveying the main positive and normative findings of this line of the literature, and suggesting areas in which these models could be implemented. In particular, we review studies that analyse the heterogeneity of (i) households’ income, (ii) households’ preferences, (iii) consumers’ age, (iv) expectations and (v) firms’ productivity and financial position. We highlight the results on issues that, by construction, cannot be investigated in a representative agent framework and discuss important papers modifying the findings from the representative agent literature. 相似文献

The paper refers to the well-known Tsukui turnpike theorem on convergence of optimal growth trajectories in the closed dynamic Leontief model to the maximum balanced growth trajectory, called turnpike. In the original proof of this theorem, the assumption that the matrix B of capital coefficients is non-singular plays an essential role. For many reasons this assumption, very convenient for theoretical analysis, is not always satisfied in input-output systems built for empirical purposes. This paper fills the gap between theory and empirical studies, presenting a proof that convergence of optimal trajectories towards the turnpike is also a characteristic feature of the closed Leontief model in the case when matrix B is singular. The general idea of the proof is based on the approximation of a singular matrix B by an infinite sequence of non-singular matrices. 相似文献

Inspired by the empirical findings, we include international traders to capture linkage between markets and propose a two-market heterogeneous agents model to simulate financial crisis with contagion effect. This paper manages to calibrate sudden crash behavior of US and UK stock markets during “Black Monday” of 1987 besides smooth crisis and disturbing crisis categorized in literature. It is implied that financial crisis and its contagion could be endogenous, which supports a scenario of over-valuation causing a financial crisis. In addition, the model shows that financial system could be fragile in which small shock(s) hitting individual market’s fundamental could cause financial crisis spreading to the other market. This also supports a scenario of external shock triggering a financial crisis. Lastly, to demonstrate the relevance of our model to financial markets, we manage to match typical stylized facts, especially cross-correlation which is exclusive to a multiple-market case. 相似文献

Inspired by Kajii (1992) and Askoura (2011, 2017), we introduce the notion of the weak -core for games with nonordered preferences and a continuum of agents. First, we extend the work of Kajii (1992) to games with spaces of strategies defined on Hausdorff topological vector spaces. Furthermore, we prove the nonemptiness of the weak -core. Finally, we establish the relations between normal-form games, games with nonordered preferences and games with pseudo-utilities. 相似文献

我国通货膨胀的收入分配效应分析 总被引:2,自引:0,他引:2
从理论和经验上研究了我国通货膨胀的收入分配效应。根据我国经济社会特征,通货膨胀具有调节城乡之间、不同体制企业之间和不同地区之间的收入差距的效应。对代表收入差距的基尼系数去趋势后的实证分析表明,通货膨胀可部分解释基尼系数的波动成分,其趋势成分由经济增长等因素决定。 相似文献

Economic reforms have brought about spectacular growth and vast improvements of people’s living standards in China since 1978.
In the meantime, unbalanced regional growth and income inequality have become two important concerns of future development.
Most available studies on income distribution have either focused on the rural population or on the urban citizens. This paper
stresses the importance of adopting a multi-angle approach to fully understand income inequality in China. We first use some
top-down information to form a general picture of inequality for the whole country, and then use some bottom-up household
survey data to explain in detail the development of inequality over time regarding rural/urban inequality, rural inequality,
urban inequality and inter-regional inequality, the relative importance of different income sources to overall inequality.

We investigate the relationship between education funding and educational inequality across Chinese prefectures. The decentralisation of education in China has created substantial variations in government educational expenditures, both over time and across regions. We propose that these variations relate to the budget preferences of local governors. These are age dependent with younger officials more inclined to invest in large and quantifiable infrastructure projects rather than public service provision. This provides a source of exogenous variation in local fiscal efforts to provide public education and thus permits quasi-experimental evaluation through instrumental variable identification. Our results suggest that increased education spending is linked with lower educational inequality. Moreover, we find strong evidence of heterogeneity - the magnitude of the effect is diminishing with the degree of local fiscal autonomy. 相似文献

We use a perturbation method to solve the incomplete markets model with aggregate uncertainty described in den Haan et al. [Computational suite of models with heterogeneous agents: incomplete markets and model uncertainty. Journal of Economic Dynamics & Control, this issue]. To apply that method, we use a “barrier method” to replace the original problem with occasionally binding inequality constraints by one with only equality constraints. We replace the structure with a continuum of agents by a setting in which a single infinitesimal agent faces prices generated by a representative-agent economy. We also solve a model variant with a large (but finite) number of agents. Our perturbation-based method is much simpler and faster than other methods. 相似文献

We study a pure exchange economy under incomplete markets where households have heterogeneous homothetic recursive preferences and lending and borrowing are precluded. We fully characterize the properties of the efficient allocations and the equilibrium asset price. The ownership distribution dynamics reveal the emergence of a dominant agent, who after some finite time, remains the only investor that increases asset holdings until asymptotically owning the entire wealth. Investors can be ranked according to a unique parameter that aggregates agents’ preference characteristics and we show how time discount rate, attitude towards risk and intertemporal substitution contribute to capital accumulation. 相似文献
