Money also is sunny in a retiree’s world: financial incentives and work after retirement

This paper assesses the impact of financial incentives on working after retirement. The empirical analysis is based on a large administrative individual career data set that includes information about 2% of all German employees subject to social security or in marginal employment until age 67 and their employers in the period 1975–2014. We use the classical labor supply model and differentiate between the impact of (potential) labor and non-labor (pension entitlements) income. A Heckman-type two step selection model corrects for endogeneity. We show that labor income has a positive and non-labor income a negative impact on the decision to work after retirement. Especially individuals who can substantially increase their earnings in comparison to their pension entitlements accordingly have a higher probability to work. Men are more attracted by labor earnings incentives than women. Also individuals who work until retirement are easier attracted to work after retirement by higher labor income than those with gaps between employment exit and retirement. Our results allow the calculation of the impact of changes in taxes on labor and non-labor income and changes in earnings offers by employers on work after retirement for different demographic groups.

The Impacts of Social Enterprises on Labor Market Outcomes: Evidence from Vietnam

This study examines whether social enterprise development improves labor market outcomes of the entire economy. Using the data of social enterprise and labor force survey in Vietnam, we conduct a regression analysis to address this question. We focus on the rapid growth period of social enterprises in Vietnam during the early 2010s. Our results suggest that, as the number of social enterprises increases, average labor earnings increase, the probabilities of being unemployed and being self-employed decrease, and average working hours increase. Since our study evaluates the effect of social enterprise development on the outcomes for the overall labor market rather than the social enterprise sector alone, it provides justification for promoting such a policy from policymakers’ point of view.

Sustainable Earnings: How Can Herd Behavior in Financial Accumulation Feed into a Resilient Economic System?

The paper applies a methodological tool able to frame national policies with sustainable financial flows between social groups. In effect, exchange entitlement mapping (E-mapping) shows the interdependency of capital and labor earnings across social groups, which is then accounted for in the policy planning of future financial flows for the green transition. First, the paper highlights the extent to which herd behavior feeds into capital and labor earnings by social, occupational, demographic, and regional groups for the United Kingdom, France, and Italy over the past 40 years. Second, learning from these past trends, the paper proposes a policy framing of “sustainable earning trends” to hamper or facilitate financial flows towards sectors, occupations, and regions prone to herd behavior. The paper concludes that for an economic system to be resilient, it should be able to recycle external shocks on group earnings into economic opportunities for the green transition.

Earnings growth and the wealth distribution

As measured by Gini coefficients, fractile inequalities, and tail power laws, wealth is distributed less equally across people than are labor earnings. We study how luck, attitudes that shape saving decisions, and growth rates of labor earnings balance each other in ways that simultaneously shape joint distributions across people of labor earnings, age, and wealth together with an equilibrium rate of return on savings that plays a pivotal role in balancing contending forces. Strong motives for people to save and for firms to demand capital raise an equilibrium interest rate enough to make wealth grow faster than labor earnings. That makes cross-sectional wealth more unevenly distributed and have a fatter tail than labor earnings, as in US data.

Structural Changes in Investment and the Waning Power of Monetary Policy

We argue that secular change in both the production and composition of investment goods has weakened private investment's role in the transmission of monetary policy to labor earnings and consumption. We show analytically that fluctuations in the production of investment goods amplify the response of consumption to monetary policy shocks by varying labor income for hand-to-mouth agents. We document three secular changes that weaken this channel: (i) labor's share of value added in investment goods production has declined, (ii) the import share of investment goods has risen, and (iii) the composition of investment has shifted towards components that are less responsive to monetary policy. A small open economy, two agent New Keynesian model calibrated to match these facts implies a 38% and 26% weaker response of labor income and aggregate consumption, respectively, to real interest rate shocks in a 2010's economy relative to a 1960's economy.

Asset Pricing With Endogenously Uninsurable Tail Risk

This paper studies asset pricing and labor market dynamics when idiosyncratic risk to human capital is not fully insurable. Firms use long‐term contracts to provide insurance to workers, but neither side can fully commit; furthermore, owing to costly and unobservable retention effort, worker‐firm relationships have endogenous durations. Uninsured tail risk in labor earnings arises as a part of an optimal risk‐sharing scheme. In equilibrium, exposure to the tail risk generates higher aggregate risk premia and higher return volatility. Consistent with data, firm‐level labor share predicts both future returns and pass‐throughs of firm‐level shocks to labor compensation.

The Role of Credit on the Evolution of Wealth Inequality in the USA

In the USA, the share of household wealth held by the richest 1% increased from 23.5% in 1980 to 41.8% in 2012. This paper contributes to understanding the causes behind this increase. First, using an accounting decomposition, I show that more than half of the increase in the share of the top 1% can be attributed to a decrease in the saving rate of the bottom 99%. Second, using a heterogeneous agent model, I show that the decrease in the saving rate of the bottom groups cannot be rationalized by the reduction in the progressively of taxation or changes in the volatility and concentration of labor earnings. Lastly, I introduce a shock to the credit market into the model in the form of loosening the borrowing constraints of the economy. This shock can simultaneously match the increase in wealth concentration and the decrease of the saving rate of the economy.

Growing Income Inequality in the United States and Other Advanced Economies

This paper studies the contribution of both labor and non-labor income in the growth in income inequality in the United States and large European economies. The paper first shows that the capital to labor income ratio disproportionately increased among high-earnings individuals, further contributing to the growth in overall income inequality. That said, the magnitude of this effect is modest, and the predominant driver of the growth in income inequality in recent decades is the growth in labor earnings inequality. Far more important than the distinction between total income and labor income, is the way in which educational factors account for the growth in US labor and capital income inequality. Growing income gaps among different education groups as well as composition effects linked to a growing fraction of highly educated workers have been driving these effects, with a noticeable role of occupational and locational factors for women. Findings for large European economies indicate that inequality has been growing fast in Germany, Italy, and the United Kingdom, though not in France. Capital income and education don’t play as much as a role in these countries as in the United States.

The Return to Education in the Mid-Twentieth Century: Evidence from Twins

What was the return to education in the United States at mid-century? In 1940, the correlation between years of schooling and earnings was relatively low. In this article, we estimate the causal return to schooling in 1940, constructing a large linked sample of twin brothers to account for differences in unobserved ability and family background. We find that each additional year of schooling increased labor earnings by approximately 4 percent, about half the return found for more recent cohorts in twins studies. These returns were evident both within and across occupations and were higher for sons from lower socio-economic status families.

Accounting for Wealth-Inequality Dynamics: Methods, Estimates, and Simulations for France

Measuring and understanding the evolution of wealth inequality is a key challenge for researchers, policy makers, and the general public. This paper breaks new ground on this topic by presenting a new method to estimate and study wealth inequality. This method combines fiscal data with household surveys and national accounts in order to provide annual wealth distribution series, with detailed breakdowns by percentiles, age, and assets. Using the case of France as an illustration, we show that the resulting series can be used to better analyze the evolution and the determinants of wealth-inequality dynamics over the 1970–2014 period. We show that the decline in wealth inequality ends in the early 1980s, marking the beginning of a rise in the top 1% wealth share, though with significant fluctuations due largely to asset price movements. Rising inequality in savings rates coupled with highly stratified rates of returns has led to rising wealth concentration in spite of the opposing effect of house price increases. We develop a simple simulation model highlighting how changes in the combination of unequal savings rates, rates of return, and labor earnings that occurred in the early 1980s generated large multiplicative effects that led to radically different steady-state levels of wealth inequality. Taking advantage of the joint distribution of income and wealth, we show that top wealth holders are almost exclusively top capital earners, and increasingly fewer are made up of top labor earners; it has become increasingly difficult in recent decades to access top wealth groups with one's labor income only.
