Rising Earnings Inequality in Sweden: The Role of Composition and Prices

The rise in cross‐sectional earnings inequality in Sweden between 1990 and 2002 is decomposed into changes in market prices of observable characteristics, changes in the composition of the labor force across demographic groups and industries, and changes in unobservables. The Swedish experience is then compared with that in the United States. In both countries, the rise in earnings inequality is a consequence of rising upper‐tail dispersion. Contrary to the U.S. experience, where the rise is largely driven by changing market prices of observables and increased residual dispersion, shifts in the Swedish labor‐force composition have contributed positively to the rise in the p90–p50 gap. The rise in the Swedish p99–p90 gap, however, is entirely accounted for by changes in prices and residual dispersion.     

EFFICIENCY AND LABOR MARKET DYNAMICS IN A MODEL OF LABOR SELECTION

This article characterizes efficient labor market allocations in a labor selection model. The model's crucial aspect is cross‐sectional heterogeneity for new job contacts, which leads to an endogenous selection threshold for new hires. With cross‐sectional dispersion calibrated to microeconomic data, 40% of empirically relevant fluctuations in the job‐finding rate arise, which contrasts with results in an efficient search and matching economy. The efficient selection model's results hold in partial and general equilibrium, as well as with sequential search.     

迈向统一市场：基于城市数据对中国商品市场分割的测算与分析*

统一的国内大市场对区域专业化分工和发挥规模效应起着重要作用。本文采用价格法系统测算了2001-2015年间各城市的商品市场分割程度，并考察了影响商品市场分割的地区因素。研究发现：（1）除2008-2009年商品市场分割短暂加剧以外，2001-2015年间商品市场分割程度整体呈现下降态势。（2）各地区在市场一体化进程方面存在明显差距，东南部地区的市场整合程度高于西部地区。全国层面的商品市场分割程度大于局部地区层面的市场分割程度。（3）地区间竞争会促使地方政府干预市场，加剧商品市场分割；而较好的经济发展条件和市场规模的扩大会减轻地区间恶性竞争，促进区域市场一体化。（4）城市层面的商品市场分割受行政区划的影响表现出一定的规律性：省界会阻碍城市之间的贸易往来，加剧商品市场分割。     

资产定价异象的泛函主成分研究

本文采用泛函主成分法研究我国A股市场中的五种资产定价异象。与传统方法相比，该方法能够分别提取特征变量与期望收益率之间的单调和非单调性关系进行研究。实证结果显示按照资产定价异象指标排序的收益率面板数据包含三个关键成分：第一个主成分代表时序市场因子在横截面上的扩展，与异象效应无关；第二个主成分代表异象的横截面“单调”效应，价值和动量异象的稳健性较差；第三个主成分代表异象的横截面“凸性”效应，与投资者交易行为引起的“分置效应”有关。     

PRICE SETTING PRACTICES IN GREECE: EVIDENCE FROM A SMALL‐SCALE FIRM‐LEVEL SURVEY

The paper documents the price setting practices followed by some 400 or so firms operating in Greece. Survey replies reveal a low percentage of firms changing prices with frequency higher than annual and staggering of price changes during the year. As to firms’ reactions to unexpected shocks, prices appear to adjust sluggishly to cost shocks with asymmetries in price adjustment across positive and negative shocks. Adjustments to increases in costs appear speedier than those to reductions in demand. The data confirm a result found for other countries: the existence of cross‐sectional variations in price setting strategies and in the extent to which prices are adjusted in reaction to unexpected shocks. The results suggest a positive association between, on the one hand, product market competition and, on the other hand, state‐dependent pricing, frequent price changes and the likelihood of a price adjustment following an adverse demand shock.     

Anatomy of Russia’s market segmentation1

Based on a relationship between price difference and demand difference among locations, the role of various market frictions in causing segmentation of the Russian goods market is analysed. The spatial sample covers most of Russian regions (70 of the 89); the data are annual, spanning 1992 to 2000. Spatial disconnectedness of regions is found to be responsible for about 70 percent of the average price differential, while the rest is caused by ‘artificial’ impediments to market integration such as regional protectionism, organized crime and intra‐region shipping conditions.     

Immigrant earnings growth: selection bias or real progress?

We use longitudinal tax data linked to immigrant landing records to study the effect of selective attrition on the estimated earnings assimilation of immigrants to Canada. Contrary to findings in the existing international literature, we show that the immigrant‐native earnings gap closes at the same pace in longitudinal and cross‐sectional data. Low‐earning immigrants are likely to leave the cross‐sectional samples over time, but the same is true for the native born. Our study suggests that immigrants to Canada have labour market participation dynamics similar to those of the native born.     

Monetary Policy Transparency in the UK: The Impact of Independence and Inflation Targeting

There is a widespread belief that the transparency of UK monetary policy has increased substantially as a result of the introduction of inflation targeting in 1992 and a number of procedural and institutional reforms which accompanied and followed it. Here, money market responses (and other data) are used to test the possibility that improved anticipation of policy moves may be the result of developments other than the institutional reforms popularly cited. We find overwhelming evidence that the switch to inflation targeting itself significantly reduced monetary policy surprises, while subsequent reforms have contributed little. Where we advance substantially on earlier work is to look at the cross‐sectional dispersion of agents’ anticipation. If the benefit of transparency is the elimination of policy surprise, there is little benefit if the averagely correct anticipations of agents conceal a wide dispersion of view.     

New evidence of regional income divergence in post-reform Russia

This article investigates regional income convergence in Russia during 2000–2008. We test the hypothesis in which income divergence across regions of the country should give place to income convergence as the country moves toward free market economy with strong market institutions. The study contributes to the existing literature by using the exponential smooth autoregressive Augmented Dickey–Fuller (ADF) unit root test in a panel setup, a novel econometric technique, which encompasses cross sectional dependence. Results show strong evidence of on-going regional income divergence in post-reform period.     

Has Labor Income Become More Volatile? Evidence from International Industry‐Level Data

Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970–2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry‐specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross‐sectional heterogeneity is substantial. If anything, the labor incomes of high‐ and low‐skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear‐cut impact.     

Real and Financial Integration in East Asia

This paper examines the real and financial integration of East Asian economies, by comparing the degree of real vs financial and global vs regional integration, before vs after the Asian crisis. First, price and quantity measures such as the size of intra‐ and inter‐regional trade, cross‐border financial assets, stock return correlation, and interest rate differentials are investigated. Second, the structural panel vector autoregression (VAR) model is constructed to analyze macroeconomic consequences of real and financial integration such as cross‐country output and consumption relation. The results suggest that (i) the degree of real integration significantly increased after the crisis, both regionally and globally; (iii) quantity and price measures showed an increased financial integration after the crisis, but the consumption relation did not; (iv) the degree of regional financial integration is smaller than that of global financial integration, based on the consumption relation; and (v) financial integration lags real integration, especially for regional integration.     

A THEORY OF THE CROSS‐SECTIONAL FERTILITY DIFFERENTIAL: JOB HETEROGENEITY APPROACH

This article presents a theory of the cross‐sectional fertility differential, which produces the negative wage–fertility relationship based on job heterogeneity. Although evidence suggests the importance of job heterogeneity in the labor market, it has largely been ignored in theories of fertility choice. I show that a theory incorporating job heterogeneity requires only standard conditions on preferences to generate the negative wage–fertility relationship, and the negative relationship derived from the model is robust to changes in economic environments (e.g., public policy and technology). Furthermore, the theory reconciles the negative cross‐sectional wage–fertility relationship with various time‐series variations in aggregate fertility.     

FURTHER EVIDENCE ON REAL INTEREST RATE EQUALIZATION: PANEL INFORMATION,NON‐LINEARITIES AND STRUCTURAL CHANGES

Previous studies applying traditional unit root tests generally have difficulty providing widespread evidence supporting the real interest rate parity hypothesis (RIPH). This paper aims to analyse the empirical fulfilment of RIPH for 17 OECD countries by employing many recently developed unit root tests. Power of the tests is raised by taking different approaches, such as using cross‐sectional information, accounting for non‐linear adjustment towards the equilibrium and allowing for structural changes. The combined results of the tests using panel information show that broad evidence in favour of RIPH prevails for 13 of the 17 countries. By contrast, univariate tests fail to make widespread rejections of the unit‐root hypothesis. Our evidence reveals a high degree of market integration for developed countries, and the effect of monetary policies as a stabilization tool might be limited at least in the long run.     

LABOUR‐MARKET ATTACHMENT AND TRAINING PARTICIPATION*

This paper examines how expected attachment to the labour market and expected tenure at a specific firm affect training participation. The results, based on cross‐sectional data from Japan, indicate that expected attachment to the labour market affects participation in both employer‐ and worker‐initiated training, while expected tenure at a specific firm mainly explains participation in employer‐initiated training. These two attachment indices explain more than two‐thirds of the sex gap in training participation. Employers in less‐competitive labour markets are more likely to offer employer‐initiated training to their workers.     

TEST OF THE CONVERGENCE HYPOTHESIS ALLOWING FOR CROSS‐SECTIONAL DEPENDENCE

A large empirical literature has investigated whether per capita output converges around a common trend across national and regional economies. The methods used in this literature assume no cross‐sectional dependence even though it is likely to be present and might be important in practice. Chang has devised a promising method of testing for unit roots in heterogeneous panels with cross‐sectional dependence. We apply her method to test whether convergence takes place across three samples of economies: 15 advanced industrial countries; a broader group of 57 countries; and the 48 contiguous US states. We find evidence of convergence for the 15 advanced industrial economies but no evidence of convergence across either the broad group of countries or the US states.     

PRICE DISPERSION AND DEMAND UNCERTAINTY: EVIDENCE FROM U.S. SCANNER DATA

I use the Prescott (1975) hotels model to explain variations in price dispersion across items sold by supermarkets in Chicago. The effect of uncertainty about aggregate demand on price dispersion is highly significant and quantitatively important: My estimates suggest that more than 40% of the cross‐sectional standard deviation of log prices is due to demand uncertainty. I also find that price dispersion measures are negatively correlated with the average price but are not negatively correlated with the revenues from selling the good (across stores and weeks) and with the number of stores that sell the good.     

Allocation effects of uncertainty on resources in Japan

This paper provides evidence of a negative association between macroeconomic uncertainty and the cross sectional dispersion of investment rate for a panel of Japanese manufacturing firms. We show that an increase in uncertainty leads to the narrowing of the cross section dispersion of investment rate and vice versa. This finding suggests that firms’ fixed capital investment behavior becomes more homogeneous in times of increased uncertainty.     

Uncovered Interest Parity: Cross‐Sectional Evidence

Uncovered interest parity (UIP) is estimated for short‐term horizons from one month to 12 months using a large number of cross‐sectional bilateral exchange rates. In contrast to conventional time‐series UIP, cross‐sectional UIP is examined with a single‐equation estimation and panel regression model estimation. The exchange rates analyzed here include a broad spectrum of countries: developed, developing, low‐inflation, and high‐inflation countries. Based on the empirical evidence, there does not appear to be a well‐publicized UIP puzzle for cross‐sectional UIP, and the slope estimates remain largely between zero and one throughout the sample periods, with a few exceptions. Evidence of UIP is more clear for low inflation countries than for high inflation countries. As interest rate maturity becomes longer from one month to 12 months, the UIP relationship becomes weaker.     

Exports,Supply Constraints and Growth: An Investigation using Regional Data

In this work we first model the role of demand‐ and supply‐side factors (labour market adjustment, productive efficiency) in explaining economic growth. Empirically testing the model, we evaluate why different growth regimes may appear in the 20 Italian administrative regions. This exercise uses a two‐stage econometric approach. Estimates for the elasticity of manufacturing output to exports are obtained from regional time series: a significant long‐run relationship indicates the existence of a demand‐constrained growth regime. We then ascertain whether the regional dispersion of supply‐side factors has an impact on the regional dispersion of growth regimes. The empirical evidence supports our expectations of strong regional differences. Southern regions are less likely to display demand‐constrained regimes. In explanation of these differences, second‐stage analysis reveals that a strong role is played by such efficiency‐enhancing factors as technological innovation, bank diffusion and ‘social capital’. No role is found for labour market rigidities.     

Assessing Market Integration in ASEAN with Retail Price Data

We assess the extent of market integration the Association of Southeast Asian Nations (ASEAN) using a comprehensive data set that contains actual local retail prices for 131 goods and services in ASEAN countries (except Laos and Myanmar) over the period of 1990–2013. We conduct two different, but complementary, approaches: analyzing price dispersion and testing for convergence to the law of one price via panel unit root tests. The 1997 Asian crisis and, to a lesser extent, the 2008 global crisis appear to have caused a considerable disruption in the process of market integration. Despite significant tariff reduction under the ASEAN Free Trade Area commitments in the past two decades, the level of price dispersion across ASEAN is higher in 2013 than in 1990. Panel unit root tests accounting for cross‐section dependence show that convergence to the law of one price holds for only a minority of retail prices, including those of traded goods, in the ASEAN markets. We also consider a nonlinear exponential smooth transition autoregressive approach and a structural break as alternative adjustment dynamics in the panel unit root tests. Overall, our results suggest that there is much to be done in ASEAN to achieve a meaningful ASEAN economic community.
