The impact of job mobility on earnings: using occupational and industrial classifications to identify job changes

According to the Bureau of Labor Statistics, the median number of years that a US worker has been with their current employer is 4.4 years. Although many job changes may not be classified as ‘career changes,’ any type of job change may have an impact on a person’s future earnings. In the present study, the following three types of job changes are examined in order to determine which ones result in higher incomes: a change in occupational status; a change in industry; or a change in both. Using data from the National Longitudinal Survey of Youth (NLSY), a log-linear wage regression with a correction for self-selection is estimated. Results suggest that changing jobs within the same industry or within the same occupation both increase a person’s income. However, a job change that is characterized by both a change in industry and occupation reduces a person’s income. The present study is one of the few studies to examine the effects of job mobility on earnings when mobility is defined in the context of changes in occupational and/or industrial classification.     

Information-eliciting compensation schemes

This paper examines the implications of the ‘residence’ approach to taxing foreign source income such as employed by the United States. It is argued that, because the repatriation of earnings to the home country investor and not the earnings themselves are typically the source of tax liability, the foreign source income tax should affect foreign investment differently depending on the required transfers of funds within the firm.One implication of viewing the tax in this way is that in order to maximize after-tax profits, a firm should finance its foreign investment out of foreign earnings to the greatest extent possible. That is, a firm's required foreign return jumps at the point at which desired foreign investment just exhausts foreign earnings. This allows us to draw a distinction between ‘mature’ foreign operations, which are at any point in time financed at the margin by investing earnings (and perhaps also pay dividends to their parent firm in the home country), and ‘immature’ foreign affiliates, which rely on funding from their parents (and should not be paying dividends). It is noted that survey evidence on multinational firm behavior is consistent with this distinction. Direct investment data indicate that mature foreign operations probably account for nearly 90 percent of U.S. foreign direct investment.The discussion then turns to investment incentives. It is shown that the home country's rate of tax on foreign source income and the presence or absence of a foreign tax credit should be irrelevant to a mature foreign operations's investment and dividend decisions. This conclusion, which conflicts sharply with the conventional wisdom, follows because the home country tax acts as an unavoidable cost. New firms' investment decisions are, on the other hand, influenced by home country taxes.     

Dividend taxes,corporate investment,and ‘Q’

Taxes on corporate distributions have traditionally been regarded as a ‘double tax’ on corporate income. This view implies that while the total effective tax rate on corporate source income affects real economic decisions, the distribution of this tax burden between the shareholders and the corporation is irrelevant. Recent research has suggested an alternative to this traditional view. One explanation of why firms in the United States pay dividends in spite of the heavy tax liabilities associated with this form of distribution is that the stock market capitalizes the tax payments associated with corporate distributions. This capitalization leaves investors indifferent at the margin between a corporation's decision to pay out dividends or to retain earnings. This alternative view holds that while changes in the dividend tax rate will affect shareholder wealth, they will have no impact on corporate investment decisions.This paper develops econometric tests which distinguish between these two views of dividend taxation. By extending Tobin's ‘q’ theory of investment to incorporate taxes at both the corporate and personal levels, the implications of each view for corporate investment decisions can be derived. The competing views may be tested by comparing the performance of investment equations estimated under each theory's predictions. British time series data are particularly appropriate for testing hypotheses about dividend taxes because of the substantial postwar variation in effective tax rates on corporate distributions. The econometric results suggest that dividend taxes have important effects on investment decisions.     

两税合并、税收筹划与盈余管理方式选择

文章以2007年的两税合并为背景,研究上市公司出于税收筹划的目的如何选择盈余管理方式。研究发现,税率下降公司由于税率下降幅度较大,税收筹划收益较高,因此进行了显著向下的应计盈余管理,而没有选择真实盈余管理方式;而税率上升公司则由于存在5年的过渡期,税收筹划收益较低,因此既没有进行显著的应计盈余管理,也没有进行显著的真实盈余管理。这意味着上市公司在进行税收筹划时会综合权衡各种避税方式的成本收益,进而选择最合适的避税方式。政府部门在制定税收政策时必须预先考虑企业可能的税收筹划策略,以达到预期的政策效果。     

Global capital markets,direct taxation and the redistribution of income

Standard fiscal theory suggests that taxation should be heaviest on the least mobile factors of production – for both efficiency and revenue reasons. A shift in tax burdens from capital to labour as economies become globally integrated is thus justified. This theoretical tradition (founded by Ramsay and continued by Mirrlees and Lucas) assumes by construction that profit taxes reduce investment and growth; and while sensitive to inter-generational equity, sidesteps the issue of income distribution within generations. In contrast, starting from Keynes’ critique of these assumptions and building on modern endogenous growth models, it can be shown that profit taxation is not necessarily injurious to productive investment. In practice, moreover, the effect of globalisation has not been to reduce tax rates on capital, but rather to erode the tax base itself (i.e. ‘tax evasion’). Improved information exchange between tax authorities, which is now being driven by fiscal insolvency in developed countries, would allow tax incidence to be shifted so as to improve income distribution within OECD countries. Such cooperation could also permit the replacement of the current discretionary system of fiscal transfers from rich to poor countries (‘development aid’) by equitable sharing of global capital tax revenue.     

The assimilation of Australian immigrants: does occupation matter?

This paper utilises the occupational attainment approach to investigate immigrant labour market assimilation, complementing other assimilation approaches such as employability, earnings, skills-match and job satisfaction. Our results show that all immigrant groups suffer from initial occupational attainment disadvantage. Worryingly, no ‘catch-up’ over time is evident – even when disaggregated to reflect different cultures and backgrounds. Nor is there much evidence that the occupational status of younger arrivals matches those of Australian born residents, despite being immersed in local mores and institutions while undertaking schooling in Australia. Newer cohorts of immigrants (those who arrived between 2000 and 2014) are also more prone to suffering an occupational penalty. We recommend policymakers subsidise bridging courses to aid recognition of overseas-obtained qualifications and encourage immigrants to obtain local qualifications that can complement their overseas-obtained work experience. This will increase their ‘Australian-ready’ skill-set and occupational attainment in their new host country.     

Absenteeism,Efficiency Wages,and Marginal Taxes

In this paper, I test the argument that increased taxes on earnings correspond to increased incentives to shirk, thus causing an increase in the rate of worker absenteeism. After fixed job effects are taken into account, panel register data on prime‐age Norwegian males who work full‐time show that a higher marginal net‐of‐earnings‐tax rate reduces the rate of absenteeism. When the net‐of‐tax rate is increased by 1.0 percent, absenteeism decreases by 0.3?0.5 percent. Injury‐related absences are less affected by tax changes than other absences. Absenteeism becomes more sensitive to tax changes as the occupational unemployment rate increases.     

Social Desirability of Earnings Tests

Abstract. In many countries, pension systems involve some form of earnings test; i.e. an individual's benefits are reduced if he has labor income. This paper examines whether or not such earnings tests emerge when pension system and income tax are optimally designed. We use a simple model with individuals differing both in productivity and in their health status. The working life of an individual has two 'endings': an official retirement age at which he starts drawing pension benefits (while possibly supplementing them with some labor income) and an effective age of retirement at which professional activity is completely given up. Weekly work time is endogenous, but constant in the period before official retirement and again constant (but possibly at a different level), after official retirement. Earnings tests mean that earnings are subject to a higher tax after official retirement than before. We show under which conditions earnings tests emerge both under a linear and under a non-linear tax scheme. In particular, we show that earnings tests will occur if heterogeneities in health or productivity are more significant after official retirement than before.     

LONG‐RUN INEQUALITY AND SHORT‐RUN INSTABILITY OF MEN'S AND WOMEN'S EARNINGS IN CANADA

This paper examines the variability of workers’ earnings in Canada over the period 1982–2006. We decompose the total variance of workers’ earnings into a ‘permanent’ component between workers and a ‘transitory’ earnings instability component over time for given workers. We then investigate the statistical relationships between these components and indicators for the business cycle. The most marked change in earnings variances in Canada since 1982 is the general rise in total earnings variance, which is essentially driven by a quite dramatic rise in long‐run earnings inequality. The patterns across age categories of the two variance components are almost opposite. Long‐run earnings inequality generally rises with age, but earnings instability is seen to generally decline with age, so that earnings instability is markedly highest among entry age workers. Unemployment rate effects are positive on almost all variance measures, while higher unemployment is associated with widened long‐run earnings differentials and greater short‐run earnings instability.     

Progressive taxation and corporate liquidation policies with mean-reverting earnings

This paper develops a real options model of an all-equity financed firm that receives mean-reverting earnings and is subject to progressive taxation. Tax progression arises from an exogenously given tax exemption threshold such that the firm pays no corporate income taxes should its earnings be less than this threshold. The firm possesses a perpetual option to liquidate its operation for a deterministic salvage value at any time. We show that the firm optimally exercises the liquidation option at the first instant when its earnings reach an endogenously determined threshold (the liquidation trigger) from above. Using numerical analysis, we show that the liquidation trigger is higher or lower than the exogenously given tax exemption threshold, depending on whether the tax exemption is below or above a unique critical level, respectively. We further show that the liquidation trigger is strictly decreasing for all tax exemption thresholds less than the critical level, and can be hump-shaped for all tax exemption thresholds greater than the critical level, especially when the salvage value is small. Corporate income taxes as such are not neutral when tax schedules are progressive.     

A general proposition on the design of a neutral business tax

A simple and general means of levying a business tax that is ‘neutral’ in the sense that it does not affect the firm's decisions at the margin is discussed. In particular, we analyze the effect of a business tax of our design on the investment decision of the firm. The well-known ‘imputed income’ and ‘immediate write-off’ methods of levying a neutral business tax are found to be special cases of our general tax design. The implication of our results is that a neutral ‘pure profits’ tax can be levied without the informational difficulties of the imputed income method or the cash flow disadvantages of the immediate write-off method.     

Compensating wage differences

The paper develops a model of the allocation of workers to jobs based on individual's preferences for job satisfaction vs earnings. Given the distribution of levels of job satisfaction and productivities, it is possible to solve explicitly for wages as a function of job satisfaction. More productive individuals will take more (less) satisfying jobs whenever the elasticity of substitution between job satisfaction and earnings is less (greater) than one. The paper also discusses the effects of inequality on earnings of high and low productivity workers and the effects of compensating wage differences on the distribution of earnings.     

Anti-discrimination rules versus income taxation in the pursuit of horizontal equity

We consider a model of prejudice-driven discrimination, where the advantaged ‘tall’ discriminate against the disadvantaged ‘short’. We employ an egalitarian social welfare function to compare anti-discrimination legal rules with a non-discriminatory (‘height-blind’) income tax.     

ARE COGNITIVE SKILLS RELEVANT IN GENDER EARNINGS DECOMPOSITIONS?

While cognitive skills are known to play an important role in labour market success, empirical evidence is mainly concentrated in its effect on returns to schooling. Evidence on the role of cognitive skills in gender earnings gap decompositions is virtually absent. I use two approaches to investigate the potential for cognitive skills to affect the size and pattern of the unexplained component of the earnings gap (‘relative discrimination’) across the wage distribution, using data from the International Adult Literacy Survey (IALS). It has been shown that when the raw cognitive score is used to control for cognitive skills, the return to schooling cognitive skills is generally underestimated. Once a distinction is made about the origins of cognitive skills (acquired in school versus outside the school), the returns to cognitive skills can vary depending on their origin. I find that using the raw score to control for cognitive skills does not result in any significantly different estimates of the unexplained component of the gap compared to when cognitive skills are not controlled for. However, once cognitive skills by origin of skill are used in place of total cognitive skills, the results change substantially for three of the five countries examined.     

Redistributive taxation as social insurance

The modern literature on nonlinear optimal taxation treats differences in income as being due to unobserved differences in ability. A striking result of this assumption is that high income agents should face a zero marginal tax rate. In this paper I assume that differences in observed income are due to exogenous differences in luck. Hence the optimal redistributive tax involves trading off the benefits due to ‘social insurance’ with the costs due to reduced incentives. I derive the optimal forms for linear and nonlinear taxes, and compute some algebraic and numeric examples. Typically high income individuals will face quite high marginal tax rates.     

THE FISCAL DIVIDEND MYTH OF AN INCOME/GST TAX SWITCH*

Reaping a windfall fiscal dividend from the taxation of the ‘underground’ economy's expenditures on ‘legitimate’ commodities is often seen as a significant advantage for a goods and services tax (GST) over an income tax. This claim ignores the changes in prices in the underground economy which would arise from the introduction of a GST. Employing a general equilibrium model which allows for tax evasion, we show that any ‘dividend’ arising from a change in the income tax/GST mix is equivalent to a rise in the income tax rate without a GST.     

Optimal unemployment insurance and redistribution

We characterize optimal income taxation and unemployment insurance in a search‐matching framework where both voluntary and involuntary unemployment are endogenous and Nash bargaining determines wages. Individuals decide whether to participate as job seekers and if so, how much search effort to exert. Unemployment insurance trades off insurance versus search and participation incentives. We also allow for different productivity types so there is a redistributive role for the income tax and show that a piecewise linear wage tax internalizes the macro effects arising from endogenous wages. Type‐specific lump‐sum taxes and transfers can then redistribute between individuals of differing skills and employment states. Our analysis embeds optimal unemployment insurance into an extensive‐margin optimal redistribution framework where transfers to the involuntarily and voluntarily unemployed can differ, and nests several standard models in the literature.     

Progressive Taxation and Wage Setting: Some Evidence for Denmark

The proposition that a progressive tax system contributes to wage moderation is studied using Danish earnings data disaggregated by occupation, gender and earnings level. Our main conclusions are that income-tax progression affects wage setting, but whether it moderates or exaggerates wage pressure is income dependent. An increase in progressivity reduces the pre-tax earnings of middle-income workers (manual male workers and moderate income earners among both male and female non-manual workers). The reverse is found for high-income earners (non-manual male workers), in that an increase in progressivity tends to raise pre-tax earnings. Finally, there is no significant effect of tax progressivity on the wages of low-income earners.

Optimal taxation in the Uzawa–Lucas model with externality in human capital

In this paper we study the optimal policy in the Uzawa–Lucas model with externality in human capital when agents value both consumption and leisure. We find that the government pursuing the first best can achieve its goal by a subsidy which depends on foregone earnings while studying and which is financed through a lump sum tax. Anyway, the optimal policy, that should be designed to provide incentives for agents to devote more time to schooling and cut both on leisure and working, is not unique. There exists an infinite number of combinations of consumption, capital income, labor income and lump sum taxes that can decentralize the first best.     

An empirical approach to distributive justice

This paper starts from the idea that it would be interesting to complement the deductive reasoning about economic justice with an empirical approach which tries to describe and interpret the actual value judgements held by the economic agents. We present results from a pilot study with 180 subjects. Factor analysis indicates that it makes sense to work with desert and compensation criteria, as most economists and philosophers do. We then illustrate that it is possible to operationalise equity judgements, estimating for each subject separately an equation describing his perception of the equitable compensatory income variation. We use the factor analysis results to construct a ‘compensation’ and a ‘desert’ index. All coefficients can be nicely interpreted and interesting patterns of interindividual variation emerge.
