SOCIAL INSURANCE AND OCCUPATIONAL MOBILITY

This article studies how insurance from progressive taxation improves the matching of workers to occupations. We propose an equilibrium dynamic assignment model to illustrate how social insurance encourages mobility. Workers experiment to find their best occupational fit in a process filled with uncertainty. Risk aversion and limited earnings insurance induce workers to remain in unfitting occupations. We estimate the model using microdata from the United States and Germany. Higher earnings uncertainty explains the U.S. higher mobility rate. When workers in the United States enjoy Germany's higher progressivity, mobility rises. Output and welfare gains are large.     

Non-Linearity and Cross-Country Dependence of Income Inequality

We use top income data and the newly developed regime-switching Gaussian mixture vector autoregressive model to explain the dynamics of income inequality in developed economies within the past 100 years. Our results indicate that the process of income inequality consists of two equilibria identifiable by high inequality and high income fluctuations, and low inequality and low income fluctuations. Our results also imply that income inequality in the United States is the driver of income inequality in other developed economies. High wages and capital gains are found to be the likely channels for the U.S. influence.     

INEQUALITY OF OPPORTUNITIES VS. INEQUALITY OF OUTCOMES: ARE WESTERN SOCIETIES ALL ALIKE?

This paper analyzes the relationship between income inequality and inequality of opportunities for income acquisition in nine developed countries during the 1990s. Equality of opportunity is defined as the situation where income distributions conditional on social origin cannot be ranked according to stochastic dominance criteria. We measure social origin by parental education and occupation and use the database built by Roemer et al. (2003 ). Stochastic dominance is assessed using nonparametric statistical tests. Our results indicate strong disparities in the degree of equality of opportunity across countries and a strong correlation between inequality of outcomes and inequality of opportunity. The U.S. and Italy show up as the most unequal countries in terms of both outcome and opportunity. At the opposite extreme, income distributions conditional on social origin are almost the same in Scandinavian countries even before any redistributive policy. We complement the ordinal comparison by resorting to an original scalar “Gini” index of opportunities, which can be decomposed into a risk and a return component. In our sample, inequality of opportunity is mostly driven by differences in mean income conditional on social origin, and differences in risk compensate the return element in most countries.     

Growth,mobility and social progress

We evaluate social progress on the basis of panel data on individual incomes by comparing the value of social welfare in the observed panel data to its value in a situation where individuals receive their first period income in each period. We derive necessary conditions for the welfare gain to be positive, and show how it can be decomposed in an effect of economic growth, a mobility effect and a cost due to aversion to time fluctuations given individuals’ ranks in the income distribution. The mobility effect, generated by reranking in the income distribution has two components: a cost due to time fluctuations in incomes and a benefit, due to equalization in time averaged incomes. We illustrate the analysis using CNEF data for Australia, Korea, Germany, Russia, Switzerland and the US. Our results indicate that the largest component of social progress is the equalization of time averaged income, induced by reranking. In countries with high growth (Australia, Korea and Russia), the growth effect is larger than the mobility effect, but in countries with low growth (Germany, Switzerland and the US), the opposite holds true. The poor performance of the US is explained by the large costs of income fluctuations and the way economic growth is distributed.     

Factor Components of Inequality: A Cross‐Country Study

This paper uses data from the Luxembourg Income Study to examine some of the forces that have driven changes in household income inequality over the last three decades of the twentieth century. We decompose inequality for six countries (Canada, Germany, Norway, Sweden, the U.K., and the U.S.) into the three sources of market income (earnings, property income, and income from self‐employment) and taxes and transfers. Our findings indicate that although changes in the distribution of earnings are an important force behind recent trends, they are not the only one. Greater earnings dispersion has in some cases been accompanied by a reduction in the share of earnings which dampened its impact on overall household income inequality. In some countries the contribution of self‐employment income to inequality has been on the rise, while in others, increases in inequality in capital income account for a substantial fraction of the observed distributional changes.     

A New Look at Intergenerational Mobility in Germany Compared to the U.S

Motivated by contradictory evidence on intergenerational mobility in Germany, I present a cross‐country comparison of Germany and the U.S., reassessing the question of whether intergenerational mobility is higher in Germany than in the U.S. I can reproduce the standard result from the literature, which states that the German intergenerational elasticity estimates are lower than those for the U.S. However, based on highly comparable data, even a reasonable degree of variation in the sampling rules leads to similar estimates in both countries. I find no evidence for non‐linearities along the fathers' earnings distribution. In contrast, the analysis shows that mobility is higher for the sons at the lowest quartile of the sons' earnings distribution in both countries. In Germany this result is mainly driven by a high downward mobility of sons with fathers in the upper middle part of the earnings distribution. The corresponding pattern is clearly less pronounced in the U.S.     

When income differences hurt or excite: The nonlinear effect of regional inequality on subjective wellbeing

Combining information from the European Union Statistics on Income and Living Conditions and the European Social Survey, we investigate the relationship between subjective well-being and income inequality using regional inequality indicators and individual data. We assume that inequality aversion and perception of social mobility affect the impact of regional inequality on subjective well-being in opposite directions. We find evidence of an inverse U-shaped effect of inequality, where inequality starts to have a positive effect on subjective well-being that becomes negative with a switch point before the average of the Gini index for the entire sample. The rationale for our nonlinear finding is that Hirschman's tunnel effect (and the positive effect of perceived social mobility) prevails for low levels of inequality, while inequality aversion and negative relative income effects are relatively stronger when inequality is higher. Robustness checks on different sample splits are consistent with the hypothesis of the two drivers.     

Institutionalism and New Trade Theory: Rethinking Comparative Advantage and Trade Policy

Gomory and Baumol (2000), and Samuelson (2004) have raised concerns about international trade’s future impact on U.S. national income. The focus is how globalization may affect the size and distribution across countries of gains from trade. Though their analysis is developed using a pure trade theoretical framework, it has strands in common with institutionalist thinking. Their findings spotlight the need for a new U.S. trade policy agenda aimed at maximizing the U.S. share of gains from trade, and complementing conventional Keynesian open economy macroeconomic analysis.     

How deep is your love? A quantitative spatial analysis of the transatlantic trade partnership

This paper explores the quantitative effects of trade liberalization envisioned in a transatlantic trade and investment partnership (TTIP) between the United States and the European Union. We use a quantitative trade model that, in contrast to other works, features consumptive and productive uses of land and we allow for labor mobility and a spatial equilibrium. Our calibration draws mainly on the world input–output database (WIOD). The eventual outcome of the negotiations is uncertain. Tariffs in E.U.–U.S. trade are already very low, however, so that an agreement will have a major impact only by eliminating nontariff barriers. These are extremely hard to quantify. We address these uncertainties by considering a corridor of trade‐liberalization paths and by providing numerous robustness checks. Even with ambitious liberalization, real income gains within a TTIP are in the range of up to 0.46 percent for most countries. The effect on outside countries is typically negative, yet even smaller. Taking land into account scales down the welfare effects strongly. Interestingly, we find that all German counties derive unambiguous welfare gains even though the model allows for negative terms‐of‐trade effects. Our analysis also implies that in order to arrive at the same welfare gains as under a TTIP, a multilateral liberalization would have to be much more ambitious for the U.S. than for the E.U.     

AN EXPLORATORY COMPARISON OF INCOME RISK IN GERMANY AND THE UNITED STATES

Using longitudinal data, 1 estimate the impact of redistribution on the welfare cost of income risk in Germany and the United States. The estimates account fully for behavior because individuals in each country have responded optimally to that country's policy. The results indicate that the welfare cost of income risk is 5.4 percent of disposable income in Germany, 8.5 percent in the U.S. Redistribution has reduced these risks from their pre-tax, pre-transfer levels by 43 percent in Germany, 21 percent in the U.S. The political importance of income security is evident in both countries, as risk relief often eliminates the net burden of redistributive taxes among middle-class households. The conclusions are robust across several models of income expectations.     

INTERNATIONAL COMPARISONS OF WEALTH INEQUALITY

This study presents reasonably comparable estimates of the size distribution of household or personal wealth for eight OECD countries—Australia, Canada, France, Germany, Japan, Sweden, the United Kingdom, and the United States. In the mid-1980s, the U.S. ranked as the most unequal and Japan the least, while the other six countries had roughly comparable levels of wealth inequality. Moreover, while wealth inequality rose sharply in the U.S. during the 1980s, it increased modestly in Sweden and showed little change or a slight decline in Canada, France, and the U.K. A comparison of time trends for the U.K. and the U.S. suggests that the relatively high wealth inequality in the U.S. in the 1980s represents a marked turnaround from the 1950s, when the U.S. was considerably more equal in terms of wealth ownership than the U.K. Comparative results for the two countries hold for both conventional (marketable) wealth and for augmented wealth, which includes a valuation of public and private pension wealth.     

Is Trade Liberalization an Important Cause of Increasing U.S. Wage Inequality? The Interaction of Theory and Policy

The majority of mainstream economists believe that globalization and trade liberalization have had a minor role in increasing U.S. wage inequality. A minority argues that capital mobility and outsourcing indicate a larger effect. This paper first surveys these views, and then argues that how we understand the policy consequences of trade liberalization helps determine the character of our analysis of the issue itself. Thus, a shift in policy perspective, to consider the "equity costs" of trade liberalization in terms of eroded U.S. labor market institutions, produces a larger framework for analyzing the consequences of globalization and trade liberalization than is available in traditional comparative advantage efficiency reasoning. From this wider perspective, trade liberalization has likely had a greater impact on U.S. wage inequality than even the minority mainstream position allows.     

UPWARD STRUCTURAL MOBILITY,EXCHANGE MOBILITY,AND SUBGROUP CONSISTENT MOBILITY MEASUREMENT: U.S.–GERMAN MOBILITY RANKINGS REVISITED

We formalize the concept of upward structural mobility and use the framework of subgroup consistent mobility measurement to derive a relative and an absolute measure of mobility that is increasing in upward structural mobility and compatible with the notion of exchange mobility. In our empirical illustration, we contribute substantively to the ongoing debate about mobility rankings between the U.S. and Germany by demonstrating that the U.S. typically does exhibit more upward structural mobility than Germany.     

International inequality in subjective well‐being: An exploration with the Gallup World Poll

In this paper we compute inequality measures over the distribution of a subjective well‐being variable constructed from a life satisfaction question included in the Gallup World Poll in almost all countries in the world. We argue that inequality in subjective well‐being may be a better proxy for the degree of unfairness in a society than income inequality. We find evidence that inequality in subjective well‐being has an inverse‐U relationship with per capita GDP , but it is monotonically decreasing with respect to mean subjective well‐being. We argue that this difference might be associated to inequality aversion in the space of utility.     

机会不平等与社会流动预期研究——基于CGSS数据的经验分析

随着"中国梦"的提出,对于居民社会流动预期的研究受到了广泛关注.现有文献对于社会流动预期影响因素的相关研究较为匮乏,文章在政府以实现社会公平正义为目标的改革背景之下,研究我国机会不平等对居民社会流动预期的影响,具有重要的理论和现实意义.研究表明:机会不平等作用于社会流动预期的总效应为正,即当前机会不平等程度越高的地区,人们向上的社会流动预期越显著;并且,这种正向影响在家庭背景条件较差、年龄较大、受教育程度较高以及非农业户籍群体中更加显著.文章认为,在政府以实现社会公平正义为目标的改革背景下,人们预期未来机会不平等程度会下降,导致机会不平等直接效应的不利影响受到间接效应的抵消,从而出现上述看似"有悖常理"的结论.实证结果也在一定程度上证实了间接效应的存在.因此,相对于当前现实存在的机会不平等,人们对未来机会不平等变化的预期对其社会流动预期的影响更为突出.政府部门应当在贯彻落实公平政策的同时,实施必要的预期管理,增强人们对政府部门的信任,使其保持对未来改革政策的乐观预期,从而维持当前较为良好的居民社会流动预期.     

The changing international transmission of U.S. monetary policy shocks: Is there evidence of contagion effect on OECD countries

We study the changing international transmission of U.S. monetary policy shocks to 14 OECD countries over the period 1981Q1–2010Q4. The U.S. monetary policy shock is defined as unexpected change in Effective Federal Funds Rate (FFR). We use a time varying parameter factor augmented VAR approach (TVP-FAVAR) to study the EFFR shocks together with a large data set of 265, major financial, macroeconomic and trade variables for U.S., Canada, France, Germany, Italy, UK, Japan, Australia, Spain, Norway, Sweden, Switzerland, Finland and New Zealand. Our main findings are as follows. First, negative U.S. monetary policy shocks have considerable negative impact on GDP growth in the U.S., Canada, Japan and Sweden while most of the other member countries benefits. Second, the transmission to GDP growth has increased in OECD countries since the early 1980s. We also detect a more depressed GDP over medium term in the U.S., Canada, Japan, Australia, Norway and Sweden over the recent global financial crisis. Third, the size of U.S. monetary policy shocks during financial turmoil periods were unusual than normal periods and varies overtime. The financial crisis (2008–2009) is evidenced by decline in residential investment in the U.S. and propagation of this shock to Canada, Germany, Japan, Switzerland and New Zealand over the recent period. U.S. monetary policy shocks reduce share prices in most of the OECD countries; this impact is more pronounced over the turmoil period. Asset prices, interest rates and trade channel seem to play major role in propagation of monetary policy shocks.     

New insights into the nonlinearity of Okun's law

We estimate Okun's relationship for four European countries (France, Germany, the Netherlands and Spain) with a nonparametric procedure, without imposing a previous specific functional form. We apply the non parametric MARS methodology that endogenously detects multiple thresholds and therefore is able to identify multiple possible regimes. In addition, we control for the Euro area crisis to capture possible effects of the economic activity of neighbour countries on domestic unemployment rate variations. Our results confirm the existence of two regimes in each country but significantly different thresholds across countries. The form of Okun's relationship for Germany, France and the Netherlands are similar and quite different from Spain where it is much steeper. Differences between Okun coefficients below and above the threshold are consistent with the “firm's risk aversion hypothesis”, but different thresholds across countries may be related to the “labour hoarding hypothesis”. The negative value of the threshold in Spain may reflect the “institutional rigidity hypothesis”. Finally, the fact that the Euro area crisis may affect the domestic Okun's law is consistent with decision makers with risk aversion who use information from the economic area they are operating in. These results not only potentially enrich Okun's law estimations but also open the debate over how the different theoretical hypothesis intervene and shape Okun's law for each country.     

RELATIVE INEQUALITY AND POVERTY IN GERMANY AND THE UNITED STATES USING ALTERNATIVE EQUIVALENCE SCALES

We use data from the Luxembourg Income Study to show the sensitivity of measures of relative economic well-being of persons in the U.S. and Germany using official equivalence scales and consumption-based country-specific equivalence scales developed for the two countries. Overall inequality and poverty levels are found not to be sensitive to the equivalence scale used. However, the official German equivalence scale yields quite different results from the others with respect to the relative income and poverty levels of vulnerable groups within the population, especially older single people.     

A simple preference foundation of cumulative prospect theory with power utility

Most empirical studies of rank-dependent utility and cumulative prospect theory have assumed power utility functions, both for gains and for losses. As it turns out, a remarkably simple preference foundation is possible for such models: Tail independence (a weakening of comonotonic independence which underlies all rank-dependent models) together with constant proportional risk aversion suffice, in the presence of common assumptions (weak ordering, continuity, and first stochastic dominance), to imply these models. Thus, sign dependence, the different treatment of gains and losses, and the separation of decision weights and utility are obtained free of charge.     

Risk in supply response: an econometric application

The impact of risk aversion on supply response is empirically estimated for selected field crops in California. As indicators of risk aversion the following surrogate variables are used: variance of past prices and yields, adjusted price to reflect the role of government support price over the market price and the dummy variables indicating price expectations. In general, the econometric estimates show a negative impact of risk aversion measured by the surrogate variables and this has implications for welfare gains resulting from price support policies aimed at stabilization.
