This paper studies the heterogeneity of households’ present bias in a heterogeneous-agent model. Our model jointly matches the average marginal propensities to consume and the wealth distribution in the USA, even when all wealth is liquid. A fiscal stimulus targeting households in the bottom half of the wealth distribution improves the consumption response. A financial literacy campaign removing present bias gets naive households out of the debt trap but harms sophisticated households’ wealth accumulation due to a lower equilibrium interest rate. Finally, we show that a borrowing cost penalty and illiquidity both discipline excessive borrowing and are therefore potential remedies for present bias and naivete.

The process of financialisation has been cast as a major contributor to increasing inequality of wealth and income in a number of advanced industrialised economies, but the nature of the link requires precise clarification. In this article, we argue that financialisation in Australia has advanced inequality, but in a particular way. Charting several features of ‘financialisation of the macroeconomy’, we accept that this process has contributed to increased inequality in the sense that the wealthy have increased their wealth faster than households and individuals at the lower end of the wealth distribution. However, there is limited Australian evidence to suggest that income redistribution has occurred as a result of the ‘financialisation of the firm’. At the level of the firm, increased inequality of wealth can be attributed directly to financialisation if firm practices are oriented to increasing shareholder value at the expense of returns to other stakeholders such as workers or suppliers, and increased income inequality can be linked specifically to financialisation through increases in earnings to financial agents. We suggest several reasons for the relative absence of a firm-level dimension of financialisation but caution that such a trend remains possible, particularly if regulation of the labour market is weakened.

This paper develops a dynamic dual-economy model and examines how the long-run outcome of an economy depends on the initial distribution of wealth and sectoral productivity. It is shown that, for fast transformation into a developed economy, the initial distribution must be such that extreme poverty is not prevalent so that most people can take education to acquire basic skills and the size of the “middle class” is large enough so that an adequate number of people can access education to acquire advanced skills. Both conditions seem to have held in successful East Asian nations, where, as in the model economy undergoing such transformation, the fraction of workers with advanced skills rose greatly and inequalities between these workers and others fell over time. In contrast, if the former condition holds but the latter does not, which would be the case for many nations falling into the “middle income trap,” consistent with facts, the fraction of workers with basic skills and the share of the modern sector rise, but inequality between workers with advanced skills and with basic skills worsens and the traditional sector persists for long periods. If the former condition does not hold, which would be true for the poorest economies, the dual structure and high inequality between workers without basic skills and others persist for very long periods. Consistently, Hanushek and Woessmann (2012) [Hanushek, Eric A. and Ludger Woessmann (2012) Do better schools lead to more growth? Cognitive skills, economic outcomes, and causation. Journal of Economic Growth 17, 267–321] find that the share of students with basic skills and that of top performance have significant effects on economic growth that are complementary to each other.

We study the dynamics of the distribution of wealth in an economy with infinitely lived agents, intergenerational transmission of wealth, and redistributive fiscal policy. We show that wealth accumulation with idiosyncratic investment risk and uncertain lifetimes can generate a double Pareto wealth distribution.

Inflation is often associated with a loss for the poor in the medium and long term. We study the short-run redistributive effects of unanticipated inflation in a dynamic optimizing sticky price model of the business cycle. Agents are heterogeneous with regard to their age and their productivity. We emphasize three channels of the effect of inflation on income distribution: (1) factor prices, (2) “bracket creep,” and (3) sticky pensions. Unanticipated inflation that is caused by monetary expansion is found to reduce income inequality. In particular, an increase of the money growth rate by one standard deviation results in a 1% drop of the Gini coefficient of disposable income if extra tax revenues are transferred lump-sum to the households.

Empirical evidence shows that entrepreneurs hold a large fraction of wealth, have higher saving rates than workers, and face substantial uninsurable entrepreneurial and investment risks. This paper constructs a heterogeneous-agent general equilibrium model with uninsurable entrepreneurial risk and capital-market imperfections to explore the implications of uninsurable entrepreneurial risk for wealth distribution and aggregate activity in an incomplete market economy. It is shown that entrepreneurial risk can substantially affect both the wealth distribution and the macroeconomy.

Standard economic theories of asset markets assume that assets are valued entirely for the consumption streams they can finance. This paper examines the introduction of the demand for status (as a function of wealth) into a model of uninsurable idiosyncratic risk—the “spirit of capitalism” (“soc”) assumption. We find that soc preferences lead to less inequality in wealth; placing wealth into the utility function leads to a shrinking wealth distribution. The drop in wealth concentration is smaller if the utility function implies status is a luxury good, but no parametrization leads to higher wealth Gini coefficients than the benchmark case. We then consider the consequences of revenue-neutral tax reforms with and without soc preferences, finding that they make little difference for this policy experiment.

It has been shown that the Ramsey growth model with agents that differ in their initial wealth endowments is compatible with a wide range of distributional outcomes, yet it is difficult to characterize under which circumstances the distribution of wealth becomes more or less unequal. In this note, we characterize the steady state distribution of wealth and compare it to the initial distribution, obtaining analytical conditions for one to be more skewed than the other. We show that whether wealth inequality increases or decreases during the transition to the steady state depends on simple and intuitive conditions on parameter values. Standard values for these parameters indicate that it is more likely that wealth inequality decreases as the economy accumulates capital.

Two phenomena are widely observed when an economy departs from an underdeveloped state and starts rapid economic growth. One is the shift of production, employment, and consumption from the traditional sector to the modern sector, and the other is a large increase in educational levels of the population. The question is why some economies have succeeded in such structural change, but others do not. To examine the question, an overlapping generations (OLG) model that explicitly takes into account the sectoral shift and human capital accumulation as sources of development is constructed. It is shown that, for a successful structural change, an economy must start with a wealth distribution that gives rise to an adequate size of the “middle class.” Once the economy initiates the “take-off,” the sectoral shift and human capital growth continue until it reaches the steady state with high income and equal distribution. However, when the productivity of the traditional sector is low, irrespective of the initial distribution and the productivity of the modern sector, it fails in the sectoral shift and ends up in one of steady states with low income and high inequality. Thus, sufficient productivity of the traditional sector is a prerequisite for development.

The paper utilizes a common approach to derive sufficient conditions for strictly monotonic behavior of three ratios along the transition to the steady state in the Ramsey–Cass–Koopmans model: the consumption–capital ratio, the consumption–output ratio (and the saving rate), and the consumption–wage ratio. These conditions are then applied to derive additional results on the transitional dynamics of the distribution of wealth in the model (when individual consumers are differentiated by their initial wealth endowments).

This paper investigates the quantitative importance of different savings motives on the distributions of wealth and consumption and aggregate capital accumulation by solving an overlapping generations model with intragenerational heterogeneity. Agents differ in age, ability, earnings shocks, and inherited bequests. In the baseline economy, there are uninsurable idiosyncratic risks associated with uncertain lifetime and earnings shocks. The model is calibrated to the U.S. economy and solved numerically. Then the allocations of the baseline economy are compared with those of an economy with complete annuity markets, one without earnings uncertainty, and one without altruism.

This paper studies the role played by differences in risk aversion in affecting the long-run distribution of wealth across agents in the context of an endowment economy. The economy is populated by two types of Epstein-Zin agents who differ only in their attitudes toward risk. By choosing riskier portfolio strategies, less-risk-averse agents enjoy returns on their investments characterized by a higher mean and a higher variance than the ones enjoyed by more-risk-averse agents. The former effect tends to make less-risk-averse agents wealthier over time, whereas the latter tends to make them poorer. The paper shows that, contrary to the results obtained using standard expected utility preferences, for some parameter values the long-run distribution of wealth is dominated by more-risk-averse agents.

We study the impact of a minimum consumption requirement on the rate of economic growth and the evolution of wealth distribution. The requirement introduces a positive dependence between the intertemporal elasticity of substitution and household wealth. This dependence implies a transition phase during which the growth rate of per-capita quantities rise toward their steady-state values and the distributions of wealth, consumption, and permanent income become more unequal. We calibrate the minimum consumption requirement to match estimates available for a sample of Indian villagers and find that these transitional effects are quantitatively significant and depend importantly on the economy's steady-state growth rate.
