Decomposing inequality change from the perspective of reranking and income growth between income groups

This paper proposes a decomposition of the change in inequality from the perspective of income groups. For every dichotomisation of the income distribution into poorer and richer parts, the decomposition allows to detect the change in the relative income gap between the two parts and the reranking between poorer and richer individuals. This decomposition approach is particularly suitable when analysts split the population between the individuals initially below the poverty line and those above the poverty line, since the decomposition allows to capture the effects of reranking and disproportional growth in income between poor and non-poor individuals and to compare these effects with those detected for the entire population. An application to Italian income data illustrates the proposed decomposition.     

Causation between health and income: a need to panic

This article tests whether health has improved income or income has improved health in OECD countries over the last 50 years. A theoretical framework for both directions of causation is first outlined. A panel time-series approach is then taken and, unlike similar work, common shocks across countries (‘cross-sectional dependence’) are taken into account in the analysis using the PANIC (Panel Analysis of Non-stationarity in Idiosyncratic and Common components) approach of Bai and Ng. It is found that better health improves income more generally while income in turn also affects health. This finding is shown to be robust to dynamic specification.     

Health insurance subsidies and the expansion of an implicit marriage penalty: a regional comparison of various means-tested programmes

Any subsidy provision for healthcare premiums, including those embedded in Affordable Care Act (ACA), has the potential to result in some couples facing an implicit penalty when married relative to unmarried. To illustrate such consequences of means-tested subsidies of health insurance premiums, we construct hypothetical households earning different levels of income who are eligible for current subsidies in the USA. and compare the estimated implicit marriage penalty faced by these households to the one faced by low-income households who are eligible for various means-tested programmes (e.g. TANF, WIC, SNAP) for each of the 48 contiguous states. We find that, like very low-income households, marriage can potentially penalize couples who receive health insurance premium subsidies by decreasing their overall disposable income by as much as 14%. We find that the ACA increases the number of households subject to marriage penalties embedded in means-tested programmes for low-income couples. This distortion will exist for any future health insurance premium subsidies that are means tested at the household income level.     

The impact of income,economic openness and interest rates on housing prices in China: evidence from dynamic panel quantile regression

The rapid growth of housing prices has attracted the attention of the whole of society in China. This article adopts the dynamic panel quantile regression to investigate the impact of income, economic openness and interest rates on housing prices in China, based on the panel data of 35 major cities from 2002 to 2012. Compared with previous studies, we can more precisely and reasonably discuss the impact of these variables on different levels of housing prices. The empirical results indicate that the impact of independent variables on housing prices is heterogeneous across quantiles. Specifically, the impact of income is positive and significant across quantiles, and the impact becomes greater at the 90th and 95th quantiles. Economic openness has a positive and significant effect at the 5th–80th quantiles, which support the Balassa–Samuelson effect, but it is insignificant at the 90th and 95th quantiles. The impact of interest rates is positive and significant at low quantiles, but the impact is negative and insignificant at high quantiles. Furthermore, we also find that the coefficients of interest rates at various quantiles are smaller. In addition, the population has a significant positive effect across quantiles. Finally, we provide important policy implications.     

Premium subsidies and demand for private health insurance: results from a regression discontinuity design

This article investigates the impact of a private health insurance (PHI) subsidy on the demand for PHI in the context of the Australian health care system. In particular, we focus on the subpopulation of elderly Australians and exploit discontinuous increases to the universal ‘PHI rebate’ that occur when people turn 65 and 70 years. Using a regression discontinuity design, we find the policy has little effect on take-up of PHI and is best interpreted as a wealth transfer to elderly Australians who already have insurance.     

绿色研发补贴与绿色技术创新 ———迎合视角的异质效应检验

绿色研发补贴是指中央或地方政府鼓励企业从事节约资源和保护环境等绿色技术创新活动的财政补贴。本文以企业的迎合行为为视角,基于中国上市公司2011—2020年的面板数据,采用双向固定效应模型实证检验了绿色研发补贴对绿色技术创新数量和质量的激励效应。研究发现：(1)绿色研发补贴能促进企业绿色技术创新;(2)绿色研发补贴对绿色技术创新激励存在异质效应,表现为对绿色技术创新数量的促进作用优于质量;(3)企业对绿色研发补贴存在迎合行为,这导致绿色研发补贴产生“强数量、弱质量”的激励异质效应;(4)绿色研发补贴的激励异质效应受到行业污染程度和环境规制强度的差异影响,表现为相较于重污染行业,绿色研发补贴对非重污染行业的激励效果更优,但迎合行为的存在也会导致“强数量、弱质量”的激励效应;环境规制强的地区绿色研发补贴能促进企业绿色技术创新“增量提质”,表明强规制能制约企业策略性创新的迎合行为。本文研究不仅深化了绿色研发补贴的量化研究,而且识别并检验了迎合行为的扭曲效应,为完善绿色研发补贴标准的制定和发放以及推动企业高质量绿色技术创新提供了微观经验支撑和对策建议。     

Price distortion and income dispersion in a labor-managed economy: Evidence from Yugoslavia

Although the standard literature on a labor-managed economy implies price distortions and spillovers of profits into wages, the evidence obtained for the Yugoslav economy does not support these predictions. In particular, price distortions in the mid-1970s are found to be small. Price deviations estimated by means of linear price models permit the calculation of excess profits and permit testing of whether they spill over into incomes. Again, contrary to what the standard theory predicts, only a small fraction of such profits is transferred into incomes.     

An extension of the Blinder–Oaxaca decomposition to a continuum of comparison groups

This paper proposes an extension of the Blinder–Oaxaca decomposition from two to a continuum of comparison groups. The proposed decomposition is then estimated for racial wage differences in urban Peru, exploiting a novel data set that allows the capturing of different degrees of mestizaje (racial mixtures).     

Mundell Revisited: a Simple Approach to the Costs and Benefits of a Single Currency Area

The paper evaluates the costs and benefits of a single currency area within a unified framework. Conventionally, it is argued that a single currency area carries a welfare loss owing to the sacrifice of exchange rate adjustment in the presence of country‐specific shocks. But in 1973 Mundell argued that a single currency area offers risk‐sharing benefits when capital markets are limited in their ability to facilitate consumption insurance. The authors construct a simple model and compare a system of independent national currencies to a single currency area. The presence of country‐specific shocks may either reduce or enhance the benefits of a single currency area, depending on the importance of exchange rate adjustment relative to risk‐sharing. In a simple quantitative analysis, we find that either regime may dominate, although the utility differences between the two regimes are very small.     

Welfare to work and subjective well-being: Evidence from a randomized control trial

I examine the effect of transitioning from welfare to full-time employment on a variety of measures of subjective well-being for a sample of long-term welfare recipients in British Columbia and New Brunswick who participated in the Self-Sufficiency Project (SSP). Individuals randomly assigned to the treatment group could receive a generous time-limited earnings supplement if they found full-time work. I use random assignment to estimate the local average treatment effect of working full time on well-being. For the complier subpopulation, I find large, positive effects on subjective well-being that persist over the longer run for New Brunswick and through roughly three years for British Columbia. Policy changes made during the experiment may explain the provincial differences.     

Long-run dynamics between trade liberalization and income inequality in the European Union: a second generation approach

The response of household debt to income inequality shocks: a heterogeneous approach

This article explores the impact of changes in income inequality on household indebtedness using Pedroni's heterogeneous panel VAR. As a result, we find evidence in support of large cross-country heterogeneity in the responses of household leverage to income inequality shocks. We also find that such heterogeneity stems from differences in the strength of financial regulations and supervision.     

A comparison of healthcare resource use for rotavirus and RSV between vulnerable children with co-morbidities and healthy children: a case control study

Abstract

Objective:

To quantify the differences in hospital length of stay (LOS) and cost between healthy and vulnerable children with cystic fibrosis (CF), insulin-dependent diabetes mellitus (IDDM), cancer, and epilepsy who contract rotavirus (RVGE) or respiratory syncytial virus (RSV).

Methods:

Hospital Episode Statistics (HES) data were collected for England, for children <5 years old, admitted between April 2001 and March 2008, using ICD-10 codes for RVGE and RSV. Cases were identified as having RVGE and/or RSV plus CF, IDDM, cancer, or epilepsy. Healthy controls had RVGE and/or RSV only, additional controls had eczema only. Cost, hospital LOS, and demographics were collected.

Results:

Four hundred and eighty-six (0.5%) cases and 101,784 (99.5%) healthy controls were admitted with RVGE or RSV, with 17,420 eczema controls. RVGE was present in 153 (31.5%) cases and 7532 (7.4%) healthy controls, and RSV in 333 (68.5%) cases and 94,252 (92.6%) healthy controls. Cases were older (1.1 years, SD?=?1.3 years), had greater LOS (9.9 days, SD?=?19.9), and cost more (£3477, SD?=?£7765) than healthy controls (age?=?0.2, SD?=?0.5, p?<?0.001; LOS?=?1.9 days, SD?=?3.1, p?<?0.001; cost?=?£595, SD?=?£727, p?<?0.001). Cost for cases was 6-times greater than healthy controls (p?<?0.001). Controls had a 0.3 day greater LOS (p?<?0.001) with RSV, but a £17 (p?=?0.085) lower mean cost than RVGE.

Conclusion:

RVGE and RSV are more serious diseases in vulnerable children, requiring more intense resource use. The importance of preventing infection in vulnerable children is underlined by hygiene and appropriate isolation and vaccination strategies. When universal vaccination is under consideration, as for rotavirus vaccines, evaluation of a vaccination programme should consider the potentially positive impact on vulnerable children.

Limitations:

Limitations of the study include a dependency on accurate coding, an expectation that patients are identified through laboratory testing, and the possibility of unidentified underlying conditions affecting the burden.     

Analysis of long-run benefits from international equity diversification between Taiwan and its major European trading partners: an empirical note

This paper employs four cointegration test approaches, PO, HI, JJ and KSS, to test for pairwise long-run equilibrium relationships between Taiwan's stock price index and each of the stock price indexes of four European markets – French, German, Dutch, and British stock markets. The results from these four tests are robust and clearly consistent in suggesting that the Taiwan stock market is not pairwise cointegrated with the four European stock markets. This provides strong evidence that there exist long-run benefits for Taiwan investors diversifying in the equity markets of Taiwan's major European trading partners, France, Germany, Holland, and the UK, over the sample period considered from 6 January 1998 to 30 May 2002. These findings could be valuable to Taiwan individual investors and financial institutions holding long-run investment portfolios in the equity markets of France, Germany, Holland, and the UK.     

The relationship between wealth or income and time preference is empirical, not apodictic: a critique of Rothbard and Hoppe

There is no doubt that when income or wealth increases, impatience for present goods declines. When time preference for the present falls, interest rates decline as well. But is this phenomenon a necessary condition of human action as Rothbard and Hoppe contend? This is widely thought to be true when a man is on the very verge of death. There is an aphorism according to which “a drowning man will grasp even at the blade of a sword.” In this view, someone who is starving will not postpone the consumption of food for tomorrow that is necessary to keep him alive today. But we disagree. And what is the situation under more ordinary circumstances far removed from starvation? We argue in this paper that, contrary to Rothbard and Hoppe, under these conditions it is a reliable but only a broad empirical generalization that time preferences and interest rates are inversely related to wealth or income, it is not a matter of praxeology.     

Testing and applying a theory of utility: An attempt to decompose income in compensatory and scarcity rents

Data on income after tax, schooling completed, job held, age, and ‘level of satisfaction’ of 2663 members of the Dutch Consumer Union have been used to estimate regression equations of two types. Type I may be called a specification of a utility function, Type II an ‘earnings function’ (where income after tax was used as earnings). For both types a number of alternatives were estimated both with regard to mathematical shape and with regard to variables included. Defining equitable or justified income differences as differences which do not change the level of satisfaction, a formula for equitable incomes for given combinations of job, schooling and age can be derived from Type I equations. All regression coefficients are found to be lower than the corresponding earnings function coefficients. The latter can then be decomposed into a ‘compensatory’ component and a ‘scarcity rent’ component.     

More equal but not so fair: an analysis of Brazilian income distribution from 1995 to 2009

This study measures unfair inequality in Brazil between 1995 and 2009. To achieve that, we used the statistical tool developed by Almås et al. (J Public Econ 95:488–499, 2011) and the concept of “responsibility-sensitive” fairness proposed by Bossert (Math Soc Sci 29:1–17, 1995), Konow (J Econ Behav Organ 31(1):13–35, 1996) and Cappelen and Tungodden (Fairness and the proportionality principle, Discussion paper SAM 31/2007. Norwegian School of Economics and Business Administration, 2007). The results indicate that the fairness level in Brazil remained unchanged throughout the analyzed period.     

Trade efficiency and economic development: evidence from a cross country comparison

Economic theory suggests that development is enhanced through income growth, which is driven through increased trade. However, the empirical evidence of such a relationship most of the times is proved to be weak. In this study we try to determine the factors influencing this relationship by measuring ‘trade efficiency’. Using the data envelopment analysis (DEA) window method for a sample of 16 OECD countries, we obtained the efficiency scores and the optimal output levels for the inefficient countries for a time period of 5 years under consideration. Results drawn from the broadly used ratio analysis were also compared to the results derived from the DEA model. Our empirical findings show that ‘trade efficient’ countries have clear characteristics like low-exchange rates for exports, low R&D intensity, high-value intra industry trade and positive impact of net trade on their gross domestic product.     

Growth of regional economy and income inequality: county-level evidence from Florida,USA

The purpose of this paper is to find the homogeneous groups and growth factors of Florida's counties through factor analysis and cluster analysis from data sets from 1979 and 2000 and to grasp the relationship between income inequality and growth by cluster using the derived growth factors. The numbers of factors divided through factor analysis were three, and six groups were obtained from cluster analysis.

County-level evidence of this paper indicates that GI_DI and SIN have a strong effect and are statistically significant to the growth rate. Results for income inequality by county and region indicate significant differences between counties, including counties where agriculture accomplishes the primary main function. Therefore, government should adopt the following policies: minimum wage, unemployment insurance, local or state tax policies, income support programmes, and tax reform.
