On the consequences of demographic change for rates of returns to capital, and the distribution of wealth and welfare

This paper employs a multi-country large-scale Overlapping Generations model with uninsurable labor productivity and mortality risk to quantify the impact of the demographic transition towards an older population in industrialized countries on world-wide rates of return, international capital flows and the distribution of wealth and welfare in the OECD. We find that for the U.S. as an open economy, rates of return are predicted to decline by 86 basis points between 2005 and 2080 and wages increase by about 4.1%. If the U.S. were a closed economy, rates of return would decline and wages increase by less. This is due to the fact that other regions in the OECD will age even more rapidly; therefore the U.S. is “importing” the more severe demographic transition from the rest of the OECD in the form of larger factor price changes. In terms of welfare, our model suggests that young agents with little assets and currently low labor productivity gain, up to 1% in consumption, from higher wages associated with population aging. Older, asset-rich households tend to lose, because of the predicted decline in real returns to capital.     

Unemployment and debt dynamics in a highly indebted small open economy

The paper analyzes the dynamic effects of a total factor productivity shock and an interest rate risk premium shock in a highly indebted open economy. In contrast to the standard open economy framework, search unemployment and wage bargaining are introduced. We find that a negative total factor productivity shock primarily has effects on the economy's production side and on welfare, but not on its stock of foreign debt and the country specific risk premium, and large part of the adjustment happens in the short-run. In contrast, a pure increase in the country specific risk premium causes substantial dynamics and a considerable reduction in foreign debt, allowing higher consumption in the long run and creating an intertemporal welfare gain, even though unemployment increases strongly in the short-run. A 50% haircut of foreign debt significantly reduces the initial response of the unemployment rate. In case of a temporary productivity shock, sticky wages imply smaller employment, but generate higher welfare than flexible wages.     

The Impact of a Minimum‐Wage Increase on Temporary‐Contract Workers

We study the impact of the 2016 increase in the Irish minimum wage on the hours worked and the probability of job loss of minimum‐wage workers. We pay particular attention to temporary‐contract workers, who may be more susceptible to changes to their working conditions than permanent employees. The results indicate that the increase in the minimum wage had a negative and statistically significant effect on the hours worked of minimum‐wage workers, with an average reduction of approximately 0.6 hours per week. For temporary workers, the effect was greater, with a decline of approximately 3 hours per week. We find no evidence that the increase in the minimum wage led to an increased probability of becoming jobless in the six‐month period following the rate change, nor did it affect employment shares in sectors employing large numbers of minimum‐wage workers.     

Minimally altruistic wages and unemployment in a matching model with monopsony

A monopsony model with a symmetric equilibrium is developed where posting higher wages reduces employee departures. This monopsony implies that wage changes have small effects on profits so that employer altruism affects wages as well. Even selfish firms act altruistically if workers punish firms that fail to do so. If the marginal utility of income falls sharply with income, the model can explain modest responses of wages to shifts in labor demand. If there are fluctuations in the altruism required by workers, the low correlation of wages and employment and the sizes of the cyclical fluctuations in these two series can be rationalized.     

Technology shocks and labor market dynamics: Some evidence and theory

A positive technology shock may lead to a rise or a fall in per capita hours, depending on how hours enter the empirical VAR model. We provide evidence that, independent of how hours enter the VAR, a positive technology shock leads to a weak response in nominal wage inflation, a modest decline in price inflation, and a modest rise in the real wage in the short-run and a permanent rise in the long-run. We then examine the ability of several competing theories to account for this VAR evidence. Our preferred model features sticky prices, sticky nominal wages, and habit formation. The same model also does well in accounting for the labor market evidence in the post-Volcker period.     

Downward wage rigidity and business cycle asymmetries

The growth rates of wages, unemployment and output of a number of OECD countries have a strongly skewed distribution. In this paper we analyze to what extent downward wage rigidities can explain these empirical business cycle asymmetries. To this aim, we introduce asymmetric wage adjustment costs in a New-Keynesian DSGE model with search and matching frictions in the labor market. Increasing wages is less costly than cutting them. It follows that wages increase relatively fast and thus limit vacancy posting and employment creation, but they decline more slowly, leading to a strong reduction in vacancies and employment. The presence of downward wage rigidities strongly improves the fit of the model to the observed skewness of labor market variables and the relative length of expansions and contractions in the output and the employment cycles. The asymmetry also explains the differing transmission of positive and negative monetary policy shocks from wages to inflation.     

Corporate diversification and downsizing decisions: International evidence from sharp and sudden performance shocks

While firms regularly reduce workforce following sharp performance decline, diversified firms may abstain from employment downsizing by transferring capital and labor between segments (the allocative flexibility effect). However, downsizing may be more likely if a performance shock leads to efforts to reduce inefficiency in resource allocation (the inefficient internal market effect). Using a large cross-country dataset, our results provide strong support for the inefficient internal market effect. We find that diversified firms are more likely to downsize and the national employment protection and union power laws moderate this link. We also find that diversified firms with more excess employment are more likely to downsize and that downsizing following major adverse performance shocks is associated with lower level of diversification and excess employment.     

Investment in organization capital

We study a firm’s investment in organization capital by analyzing a dynamic model of language development and intrafirm communication. We show that firms with richer internal language (i.e., more organization capital) have lower employee turnover, and higher diversity in skill and wages among incumbents who are promoted from within the firm. Our results also suggest that firms in rapidly changing industries are less likely to invest in organization capital, and are more likely to have high managerial turnover. Finally, our model shows that employment protection regulations lead to more investment in organization capital but less innovation.     

Understanding the Shift in Demand for Cash Value Life Insurance

Ownership of cash value life insurance in the United States has fallen in recent decades. Changes in age cohorts, family composition, and tax laws may have contributed to this decline. We identify factors that influence the demand for cash value life insurance and test whether they alone can explain the sharp decline in ownership. Demographic and tax code changes do not explain the decrease in permanent insurance. There is a consistent downward trend in demand from 1992 to 2010—particularly among middle‐age and younger households. The fewer households who own cash value policies are on average wealthier and more financially sophisticated, suggesting that permanent life insurance is increasingly being used as a tax shield rather than as a hedge against a loss in human capital.     

Emerging Market Business Cycles: The Role of Labor Market Frictions

Emerging economies are characterized by higher variability of consumption and real wages relative to output and a strongly countercyclical current account. A small open economy model with search‐matching frictions and countercyclical interest rate shocks can account for these regularities. Search‐matching frictions affect permanent income, and increase future employment uncertainty, heightening workers' incentives to save and generating a greater response of consumption and the current account. The greater consumption response feeds into larger fluctuations in workers' willingness to work, while interest rate shocks lead to variations in firms' willingness to hire; both of these outcomes contribute to highly variable wages.     

Dividend taxes,employment, and firm productivity

The paper examines the effect of dividend taxation on employment and productivity. I exploit a dividend tax cut of 10 percentage points for closely held private corporations in Sweden. Using data on all closely held Swedish firms with exact information on employees and their wages, I find that firms with limited internal funds increase productivity and wages relative to firms with sufficient internal funds whose investment decisions are less affected by dividend taxes. My findings indicate that dividend taxes constrain firms in investing efficiently. Lower taxes can result in higher capital and labor input and, thus, in higher productivity.     

The simple dynamics of a debt crisis

Optimal growth path of an ‘impatient’, neoclassical economy is studied, when creditors impose a credit ceiling to prevent debt repudiation. The ceiling becomes binding in finite time. When the credit-constrained regime begins, foreign capital inflows and domestic investment fall abruptly. Output per-capita, consumption, and real wages gradually decline, while the real interest rate rises. These results show that debt crises, in which high external debt is associated to low growth, can occur even in the absence of unanticipated shocks, policy mistakes, or ‘debt overhang’ effects. If distortionary policies cause ‘impatient’ behavior, the model is consistent with chronic capital flight in the debtor country. (JEL F34, F32)     

Endogenous Growth,Skill Obsolescence,and Output Hysteresis in a New Keynesian Model with Unemployment

We embed skill obsolescence and endogenous growth into a New Keynesian model with search-and-matching frictions. The model accounts for key features of the Great Recession: the “productivity puzzle” and the “missing disinflation puzzle.” Lower aggregate demand raises long-term unemployment and the training costs associated with skill obsolescence. Lower aggregate employment hinders learning-by-doing, which slows down human capital accumulation, feeding back into even fewer vacancies than justified by the demand shock alone. These feedback channels mitigate the disinflationary effect of the demand shock while amplifying its contractionary effect on output. The temporary growth slowdown translates into output hysteresis.     

Taxes and stabilization in contemporary macroeconomic models

The role of proportional and procyclic labor income taxes for automatic stabilization with stochastic productivity is analyzed in a contemporary macroeconomic model based on imperfect competition. The importance of short-run nominal wage rigidity for the effectiveness of progressive taxes on labor income for stabilizing output and raising household welfare is examined in a model that yields complete analytical solutions with stochastic output shocks. Increasing the procyclicity of labor income tax rates raises welfare with and without rigid nominal wages in the model economy. With fully flexible prices and wages, a positive covariance between the distortionary tax rate and productivity reduces the volatility of production and employment. This effect disappears under nominal wage rigidity, although progressive taxation can still raise welfare by reducing the distortion caused by a proportional labor tax. With rigid nominal wages and flexible consumer goods prices, payroll taxes levied at rates that rise with output can serve as automatic stabilizers. JEL Code E62 · H20     

Job search,unemployment and savings

This paper examines optimal search policies on the basis of two alternative assumptions, first that individuals consume income as it is received, and second, that individuals can save and subsequently draw from their savings. In this model workers search for heterogeneousjobs, which are characterized by fixed wages and random duration of employment spells. Workers choose jobs which will maximize the total expected lifetime utility of consumption. The optimal steady-state job acceptance policy in both cases takes the form of a fixed partition of the set of all job offers into acceptable and unacceptable ones. In the absence of a capital market, employment duration appears to be irrelevant for the marginal job offer and all jobs offering wages which exceed the marginal one are also acceptable independent of the distribution functions of employment duration. Nevertheless, the dispersion of employment duration at inframarginal acceptable jobs affects job choice. It is shown that when individuals can save, and if current utility and probability density functions are exponential, then steady-state rates of saving during periods of employment, and of dissaving during periods of unemployment, are independent of wealth and constant. The model developed is then used to examine the determinants of unemployment and the properties of optimal savings rates, and to obtain a number of testable hypotheses about savings behavior and job security.     

Taxing Mobile Capital with Labor Market Imperfections

Taxing internationally mobile factors of production has been dismissed as an inefficient means of raising tax revenue. This paper addresses the question of whether it is efficient to tax capital at source when labor markets and the taxation of lumpsum income suffer from imperfections. Four reasons for taxing capital are identified: (i) institutional constraints rendering any taxation of profit income infeasible; (ii) market power in the demand for labor; (iii) market power in the supply of labor if it increases with the employment of capital; (iv) unemployment benefits that are not tied to net real wages. It is argued that the case for taxing capital is not particularly strong. By reinterpreting capital as energy the results are applicable to the discussion about ecological tax reforms.     

Economic Growth and Inequality: Why It Matters and What's Coming Next

This article makes the case that the recent rise in income inequality in OECD countries reflects profound changes in the economic model that previously resulted in growth, prosperity, and social progress during the second half of the last century. The author begins by citing French economist Thomas Piketty's identification of the key driver of rising income inequality as the recent sharp increase in the share of national income going to capital (defined as interest, dividends and other investment returns) and the accompanying decline in the share going to labor (in the form of wages, salaries, pension, and other work‐related benefits). For most of the last 100 years, a successful balance was struck in a majority of OECD countries between the returns to capital and labor. Within the framework of nationally defined economies, labor could effectively advocate for its share of the productivity gains by capital, and governments had the ability to constrain the free movement of capital, set labor compensation standards, and redistribute income through progressive taxation. The author explores how two developments—globalization and the rise of machine intelligence—are disrupting this social contract and reshaping our economy and society. The combination of these two developments, by accelerating the flow of income to capital and away from labor, is eroding the historical relationship between capital, labor, and governments that has long prevailed in most OECD countries. As this happens, we are seeing rising income inequality and the erosion of the middle class, which had been the driver of economic growth for most of the past century. Indeed, the thesis of Piketty's book, Capital in the Twenty‐First Century, is that such an effect may well be taking us back to the pre‐20th century norm of high income inequality and low economic growth. In his closing arguments, the author suggests that avoiding this scenario will be more complicated than simply raising taxes on capital, as proposed by Piketty. It may well require a fundamental rethinking of the role of employment as the primary mechanism for income distribution in society and how we prepare our workforce for an economy and society in which the concept of work will be radically redefined.     

The Impact of Changes in Job Security Regulations in India and Zimbabwe

Employment laws in India and Zimbabwe require employers to obtainpermission from the government to retrench or lay off workers.The effect of these laws on the demand for employees in 64 manufacturingindustries is examined using time series data. Little evidenceis found indicating slower adjustments in employment levelsand hence retardation in any structural adjustment followingthe new laws. However, in both countries a substantial declinein the demand for employees (other things equal) followed thenew legislation. In Zimbabwe it is difficult to be precise abouta causal connection between the drop in the demand for labor(allowing for concurrent increased wages) and the new legislationbecause enactment occurred simultaneously with Independence;however, the current economic climate induced high levels ofinvestment in capital but not investments in long-term commitmentsto employees. But in India further evidence supports a causalconnection: larger establishments covered by the job securityregulations tended to experience a decline in the demand forlabor while smaller, uncovered enterprises in the same industriesdid not; moreover the decline in demand for employees acrossindustries in India was larger where the private sector predominates,where larger establishments covered by the new laws are important,and where a smaller proportion of employees are union members.Thus in both countries the policy implemented to protect jobsmay have resulted in far fewer jobs.     

The Impact of Children on Women's Paid Work*

This paper investigates how and when differences in work behaviour between men and women develop, focusing on the evolution of the gender gaps over the period of family development. The findings support the theory that gender differences in the formal labour market stem from the presence of children in the home and that childbirth and children entering school are critical times in women's employment. Births mark a dramatic decline in participation in work for women, while school entry is a time of considerable turnover in participation. The length of absence from work following a subsequent birth is closely related to whether the mother was in work between births, while maternity pay and leave entitlements appear to influence the precise timing of the return to work. In addition, a return to work following birth is often only temporary. The gradual decline in women's relative wages following the first birth appears to stem from the accumulation of several shorter periods of unusually low wage growth for women around the times of birth and school entry. There is also a sharp movement into part‐time work for women following childbirth and a transition towards non‐permanent positions and non‐supervisory roles at both critical points.     

Productivity,restructuring, and the gains from takeovers

This paper investigates how takeovers create value. Using plant-level data, I show that acquirers increase targets' productivity through more efficient use of capital and labor. Acquirers reduce capital expenditures, wages, and employment in target plants, though output is unchanged. Acquirers improve targets' investment efficiency through reallocating capital to industries with better investment opportunities. Moreover, changes in productivity help explain the merging firms' announcement returns. The combined announcement returns are driven by improvements in target's productivity. Targets with greater productivity improvements receive higher premiums. These results provide some first empirical evidence on the relation between productivity and stock returns in takeovers.
