Married couple work participation and earnings elasticities: evidence from tax data

This paper uses administrative tax panel data to estimate work participation and earnings elasticities of married couples by exploiting variation in tax policy. Not only may individuals alter labor supply by working more or less in response to changes in tax policy, they may also alter reported earnings or shift income between taxable and tax-deferred compensation. As a result, in addition to estimating the standard extensive and intensive labor supply elasticities, we also examine elasticities by type of income (wage earnings vs. self-employment earnings) and compensation (taxable vs. tax-deferred). We find that wives have more elastic work participation and earnings than husbands. Furthermore, self-employment income is more responsive to net-of-tax price changes than wage earnings for both husbands and wives, suggesting that it is easier for the self-employed to alter their work hours, work intensity, and/or reported income than wage earners. Finally, we find that wives respond to changes in the net-of-tax price of earnings by altering the amount of earnings subject to current-year taxes through adjustments of tax-deferred contributions to employer-provided retirement accounts.     

Employment and wage effects of a payroll-tax cut—evidence from a regional experiment

In this paper, we evaluate the effects of a regional experiment that reduced payroll taxes by 3–6 percentage points for 3 years in northern Finland. We match each firm in the target region with a similar firm in a comparison region and estimate the effect of the payroll tax reduction by comparing employment and wage changes within the matched pairs before and after the start of the experiment. According to our results, the reduction in the payroll taxes led to an increase in wages in the target region. The point estimates indicate that the increase in wages offset roughly half of the impact of the payroll tax cut on the labor costs. The remaining labor cost reduction had no significant effects on employment.     

Comparing the top and the bottom income earners: Distribution of income and taxes in the United States

Tax reform is again at the center stage as Congress grapples with ideas to reduce the US budget deficit and the country readies itself for another election year. Given this unusually charged tax reform season, populist and party rhetoric appears to the general population to have largely replaced reasoned debate as politicians, economists and pundits “cherry pick” facts to justify their claims. Our contribution to the current debate on tax equity is that this is one of the very few studies that jointly consider the impact of payroll and income taxes. Most tax equity studies focus only on the federal income tax and as such issue misleading implications. It is important to jointly consider payroll and income taxes because (a) for taxpayers in lower income ranges, the payroll tax burden outweighs the income tax burden, while (b) for higher income taxpayers income from wages above $106,800 ($110,000 in 2012) are payroll-tax free, and (c) other sources of income, namely dividends and capital gains, are not subject to payroll taxes at all. Thus, we provide a more comprehensive picture of the overall progressivity (or lack thereof) exhibited by the current tax laws. In addition, we also consider how some often-raised tax proposals would prospectively affect income inequality and tax progressivity.     

Funding a PAYG pension system: the case of Italy

Italy is characterised by a mature pay‐as‐you‐go social security system and by particularly adverse population projections. Given these trends, the social security contribution rate is expected to increase above its current high level. This hinders the development of employer‐provided pension funds and introduces a significant wedge between labour cost and earnings that discourages both labour demand and labour supply. Any proposal to reduce payroll taxes and to reform the system in the direction of partial funding has to cope with the state of Italian public finances. Italy has to comply with the Stability and Growth Pact that imposes constraints on budget deficit and debt trends. Using micro data from the Bank of Italy's Survey of Household Income and Wealth and official population projections, we estimate future employment trends under different demographic and macroeconomic scenarios and compute the cost of the transition. We show that it would be substantially reduced if positive effects on employment were induced by the payroll tax reduction.     

Horizontal Equity and the Taxation of Employed and Self-Employed Workers

The schedular system of income tax in the UK frequently comes under attack, not least in relation to the distinctions it draws between the tax treatment of the employed and the self-employed. However, on examination, it appears that non-schedular systems of taxation share both these distinctions and the difficulties that arise from them, albeit to varying degrees. The division between employed and self-employed is also problematic for social security systems. These difficulties are found, to a greater or lesser extent, in all the jurisdictions studied by the authors. It may be argued that all or some of the tax and social security differences are justified by fundamental economic and legal differences between the nature of employment and self-employment relationships. This may be true where the relationships compared are unambiguously, on the one hand, employment and, on the other, self-employment. However, there have always been non-standard relationships that combine characteristics of both these broad categories. This grey area appears to be increasing with changing work patterns. Consequently, the simple dichotomous system adopted by the UK tax and social security systems has come under pressure. This article considers the problems arising from this situation and some of the ideas that have been put forward to deal with them. JEL classification: H24, K34.     

Mitigating America's demographic dilemma by pre-funding social security

Financing Social Security benefits at current levels implies significant increases in payroll taxes within the next 20 years under current US demographic developments. Using a general-equilibrium overlapping-generations model with realistic patterns of fertility and lifespan extension, this study shows that future generations would be harmed during the demographic transition due to rising payroll taxes, which crowd out savings and slow real wage growth below the rate of technological progress. A faster rate of technological progress would mitigate only some of the payroll tax increase and its economic consequences but could not overcome them. Addressing the financing problem by reducing Social Security benefits as needed or by raising the eligibility age for benefits imposes major welfare losses on current or near term retirees. By contrast, a pre-funding of Social Security financed with consumption taxes more evenly spreads the welfare losses across generations, and it helps future generations, especially the poor, by stimulating capital formation.     

Globalisation,taxation and inequality

Today's tax systems, in which value-added taxes and payroll taxes play a prominent role, are largely creations of the 1950s. We need to invent modern tax systems adapted to the reality of the 21^st century: the growing importance of capital and the rise of inequality. This article reviews some of the challenges involved with increasing the progressivity of tax systems in a globalised world and discusses how these challenges could be overcome. I make the case for new and more ambitious forms of international cooperation and for modern forms of wealth taxation.     

Environmental Tax Reform in a Small Open Economy With Structural Unemployment

The paper examines the effects of an environmental tax reform in a small open economy with decentralised wage bargaining, monopolistically competitive firms and equilibrium unemployment. There is a tradable and a non-tradable sector and all firms use labour as well as an imported polluting factor of production (energy). A key result is that a tax on energy, recycled to reduce the payroll tax, reduces unemployment if there is a tradable sector wage premium. However, even if energy taxes may boost employment, welfare will not necessarily improve. Numerical simulations suggest that energy taxes in general provide an environmental dividend but also reduce real GDP.     

Fiscal policy with banks and financial frictions

We assess the role of banks to the transmission of optimal and exogenous changes in fiscal policy to the economy. We built-up a dynamic stochastic general equilibrium model with patient and impatient agents, banks and a government to find that banks and their associated capital-adequacy constraint mitigate the negative spill-over effects to the economy from higher taxes. Specifically, we confirm that labour income tax is the most distortionary fiscal instrument. The optimal choice of a housing tax is the most favorable funding source to a temporary increase in public spending. The combination of housing and labour taxes is the most preferred tax bundle to be optimally chosen under negative output shocks. Moreover, a permanent increase in housing tax is beneficial if it is welfare enhancing and the existence of banks benefits mainly impatient households under permanently higher consumption taxes. Finally, these results remain robust to various robustness checks.     

Labor tax reform, unemployment, and search

A key obstacle to reducing payroll taxes in many industrialized and transition countries is the direct revenue loss to the government that it implies. This paper studies a simple and practical labor tax reform of reducing a payroll tax and increasing a progressive wage tax that keeps the marginal tax wedge unchanged. Such a strategy increases employment, reduces the equilibrium unemployment rate, and increases public revenue as long as workers do not have all the bargaining power in wage negotiations. Moreover, welfare rises if workers’ bargaining power is sufficiently large to exceed a critical value determined by the second-best Hosios condition.      

Minority self-employment in the United States and the impact of affirmative action programs

In this paper I examine changes in self-employment that have occurred since the early 1980s in the United States. It is a companion paper to a recent equivalent paper that related to the UK. Data on random samples of approximately twenty million US workers are examined taken from the Basic Monthly files of the CPS (BMCPS), the 2000 Census and the 2006 American Community Survey (ACS). In contrast to the official definition of self-employment which simply counts the numbers of unincorporated self-employed, we also include the incorporated self-employed who are paid wages and salaries. The paper presents evidence on trends in self-employment for the US by race, ethnicity and gender. Evidence is also presented for construction which has self-employment rates roughly double the national rates and where there are strikingly high racial and gender disparities in self-employment rates. The construction sector is also important given the existence of public sector affirmative action programs at the federal, state and local levels directed at firms owned by women and minorities. I document the fact that disparities between the self-employment rates of white men and white women and minorities in construction narrowed in the 1980s, widened during the 1990s after the US Supreme Court’s decision in Croson but then narrowed again since 2000 after a number of legal cases, which found such programs constitutional. Despite this substantial disparities remain, particularly in earnings. I also find evidence of discrimination in the small business credit market. Firms owned by minorities in general and blacks in particular are much more likely to have their loans denied and pay higher interest than is the case for white males. This is only partially explained by their lack of creditworthiness and is consistent with a finding of discrimination in the credit market by banks.     

A social security fallacy

The article investigates whether compulsory old age provisions are justified from an economic point of view. According to a standard argument, some people would not provide sufficiently for their old age in the absence of a compulsory pension system — they would become a charge to the public. This free rider problem can be solved by mandatory lump sum contributions. However, if contributions depend on labour income, as they do in reality, potential free riders consider them as payroll taxes — even if the pension system is fully funded and actuarially fair. Therefore, compulsory contributions which are related to earned income do not solve an economic problem which cannot be tackled by the tax system as well. Put differently, there exists no economic justification for compulsory contributions, the standard argument is simply false.     

The downside of formula apportionment: evidence on factor demand distortions

This paper investigates the impact of corporate taxes on the input factor choice of multi-jurisdictional entities (MJEs) under a formula apportionment (FA) regime. Our testing ground is the German local business tax that applies FA regulations with income apportionment according to the relative payroll share. Using unique data on the population of German firms, we find that MJEs distort their employment and payroll costs in favor of low-tax locations. On average, a 1-percentage-point-increase in the tax rate differential between an affiliate and foreign group members is found to lower the affiliate’s payroll to capital ratio by 1.9%.     

National income taxation and the geographic distribution of population

We study how different national taxation schemes interact with geographic variation in productivity and consumption amenities in determining regional populations. A neoclassical migration equilibrium model is used to analyze the current nominal income tax system in Norway. The analysis is based on estimated regional income differences accounting for both observable and unobservable individual characteristics and the value of experience. Given regional differences in incomes and housing prices, quality of life and productivity are calibrated to model equilibrium. Compared to an undistorted equilibrium with lump-sum taxation, nominal income taxation creates a disincentive to locate in productive high-income regions. The deadweight loss due to locational inefficiencies is 0.18% of gross domestic product (GDP). We study real income taxation and equal real taxes as alternative tax systems. Both alternatives generate a geographic distribution of the population closer to the undistorted equilibrium, and hence with lower deadweight loss. In an extension of the analysis, we take into account payroll taxes. The existing regionally differentiated payroll taxes to the disadvantage of cities generate a deadweight loss of 0.22% of GDP in an economy with lump-sum income taxation. The two distortionary taxes interact and strengthen each other and the combined distortionary effect of income and payroll taxation in the Norwegian system is 0.46% of GDP.     

Taxes

This is a compendium of notes on taxes. Section 2 presents a general tax scheme. It is a tax on value added by labour and capital that does not favour one or the other. Section 3 contrasts taxation of business income for pass-through entities and corporations. Section 4 discusses property taxes as taxes on housing services and so a form of income tax. Section 5 turns to wealth taxes. The closing Section 6 attempts to explain why people donate to nonprofits but minimise tax payments to governments, even though governments and nonprofits engage in many of the same activities.     

Effective labor taxation and the international location of headquarters

Profit taxes are widely acknowledged to influence the location of firms’ headquarters. This paper sheds light on the role of aspects of labor taxation for the international location of headquarters. While profit taxes can be avoided in various ways, it is much harder for firms to manipulate the firm-specific labor tax base so that labor taxes may be relatively important for firm location. We construct a unique data set of effective labor taxes in 120 countries and use data on the location of 35,206 firms to analyze the impact of labor income tax rates, the progressivity of the income tax schedule, and social security contributions on firms’ decisions where to locate their headquarters. The findings suggest that both a higher progressivity of the tax system and higher (employee- and employer-borne) social security contributions negatively influence a country’s attractiveness for headquarters location. Hence, a one percentage point increase in these payroll taxes, reduces the probability of a country to attract headquarters by 6.1 %. The results prove robust in various empirical model specifications and subsets of the data.     

THE EFFECT OF TAX PREFERENCES ON HEALTH SPENDING

In this paper, we estimate the effect of the tax preference for health insurance on health care spending using data from the Medical Expenditure Panel Surveys from 1996-2005. We use the fact that Social Security taxes are only levied on earnings below a statutory threshold to identify the impact of the tax preference. Because employer-sponsored health insurance premiums are excluded from Social Security payroll taxes, workers who earn just below the Social Security tax threshold receive a larger tax preference for health insurance than workers who earn just above it. We find a significant effect of the tax preference, consistent with previous research.     

What do taxpayers prefer: Lower taxes or a better year-end position? A research note

What do people prefer, lower taxes or better year-end position? To our knowledge this is the first study that examines which component of individuals’ tax outcome, total tax or year-end position, drives their perceptions regarding their tax outcome as well as the legislation responsible. Based on prior economic and tax literature, especially borrowing from prospect theory and mental accounting, we predict that people are more likely to anchor on their prepayment position rather than on the total taxes in forming their perceptions about their tax position and their views on tax law changes. Based on a sample of 98 U.S. taxpayers we find that our predictions are supported. Specifically, we find that (1) people prefer a better year-end position than lower taxes; and (2) this preference is consistent regardless of whether they are in a refund or tax due position. Implications for public policy and accounting practitioners are also discussed.     

The Effective Tax Burden of Companies and of Highly Skilled Manpower: Tax Policy Strategies in a Globalised Economy*

Company taxes and taxes on highly skilled labour both influence the attractiveness of a particular region as a location for investment. We measure the effective tax burden on capital investment and on highly qualified labour in 33 locations across Europe and the United States. We then correlate both types of tax burden in order to study the different tax policy strategies applied in different countries. We find that effective tax rates on companies and on highly skilled employees are closely correlated for a number of countries. Ireland and most new EU Member States impose relatively lower taxes on capital investment than on highly skilled manpower. Conversely, in the US, companies are taxed heavily but the effective tax rate on highly skilled employees is moderate.     

The role of accountancy firms in tax avoidance: Some evidence and issues

As entrepreneurial businesses, accountancy firms have supplemented their traditional trade of selling accounting and auditing services by diversifying into a variety of other products and services. They have developed organisational structures and strategies to sell tax avoidance schemes to corporations and wealthy individuals. The sale of such services shifts tax burdens to less mobile capital and less well-off citizens. It also erodes the tax base and brings the firms into direct conflict with the state. This paper provides some evidence of the strategies and tactics used by accountancy firms to sell schemes that enable their clients to avoid corporate, sales and payroll taxes. Such strategies stimulate reflections upon the possible trajectories in the development of accountancy firms and social consequences of their trade.
