Payroll Taxes and the Decision to be Self-Employed

This paper investigates and quantifies the role of payroll taxes in the decision to be self-employed. It examines the effects of introducing into the labour market a payroll tax which taxes employers, but which exempts the self-employed. It exploits two changes in the tax legislation to confirm that it is changes in legislation and not other sector specific trends that are driving the results. Our findings suggest that payroll taxes do indeed influence the decision to be self-employed, with the probability of self-employment increasing as taxes on employees increase and vice versa. Furthermore, there appear to be declines in the return to self-employment caused by the tax, possibly due to inefficient allocation of labour towards self-employment.     

Nobody's business but my own: Self-employment and small enterprise in economic development

In most poor countries, small firms and self-employment are the dominant forms of business enterprise—even in the manufacturing sector. For rich countries, in contrast, self-employed people account for very small shares of manufacturing employment and output. This paper builds on Lucas [1978. On the size distribution of business firms. Bell Journal of Economics 9(2), 508-523] to ask whether structural changes of this kind are driven by productivity differences. A model, calibrated to Japanese time-series data, is shown to mimic key features of cross-country and time-series data. The results support the idea that changes in aggregate productivity account for much of the cross-country variation in establishment size and self-employment rates.     

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.     

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.     

Reform of the regulations on marginal employment lacks cohesion

Conclusion If the federal government is concerned to avoid restricting labour market dynamics in the low-income segment, it should seek a solution that tears down the ‘wall’ represented by the ceiling on marginal employment. This is not achieved by the envisaged reform concept. In fact the way forward was set out in the new government’s coalition agreement. There the government’s intention is expressed to incorporate all forms of paid employment, i.e. including self-employed activities, into the social insurance system. This would tear down the wall consisting of a high marginal tax and contribution burden that still blocks the transition from marginal work to regular part-time employment. Yet this would also require the courage to abolish flat-rate taxation in favour of an extension of individual income taxation. It seems that such a reform—as is the case with a comprehensive concept for a re-regulation of the labour market and a reform of social security—cannot be implemented in the short run. Consequently, the reform of marginal employment should be placed on the agenda of the ‘Alliance for Jobs’: these tripartite talks between employers, unions and the government, that are to be chaired by the Chancellor personally, should serve not only to bring about a reduction in German unemployment in the short-term, but also to find new, sustainable regulations for the labour market and social security. One advantage, at least, of the proposed reform of marginal employment is that it is in fact so marginal that it will not constitute an obstacle to a more comprehensive reform.     

Would a Flat‐Rate Tax Stimulate Entrepreneurship in Germany? A Behavioural Microsimulation Analysis Allowing for Risk*

When potential income tax reforms are debated, the suspected impact on entrepreneurship is often used as an argument in favour of or against a certain policy. Quantitative ex‐ante evaluations of the effect of certain tax reform options on entrepreneurship are very rare, however. This paper estimates the ex‐ante effects of the German tax reform 2000 and of two hypothetical flat‐rate tax scenarios on entries into and exits out of self‐employment based on a structural microsimulation model with econometrically estimated transition rates under risk. The simulation results indicate that flatter tax systems do not encourage people to choose self‐employment, but rather discourage them from doing so. This is explained by the reduction of entrepreneurs' income risk through progressive taxation.

Retirement and Social Security in a Probabilistic Voting Model

Why are social security transfers associated with retirement rules? This paper focuses on the political interactions between retirement and social security. Using a probabilistic voting approach, it analyzes why old people are induced to retire in order to receive pension transfers from the young. A crucial hypothesis is that leisure in old age represents a “merit good,” which is positively valued by all agents in the society, young and old. Thus, the politicians choose to tax the labor income of the old, to induce them to retire. Retirement increases the level of ideological homogeneity of the old. In fact, once retired, the elderly are more “single-minded,” since they only care about redistributive issues, such as pensions. This increase in their political power allows them to win the political game and to receive a positive transfer from the young (social security).

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.     

Agency and Tax Explanations of Security Issuance Decisions

This paper is an empirical examination of the relative roles of agency and tax considerations in corporate debt versus equity issuance decisions. Unlike earlier work, we conduct our tests on a sample of UK firms since the UK system of taxation does not create an obvious tax advantage to debt and hence affords an opportunity to evaluate the relevance of tax arbitrage considerations. We find that both tax and agency issues are important determinants of security issuance decisions. In addition, we demonstrate that our specification is robust to a variety of alternative explanations which have appeared in the empirical literature.     

Gender implications of current social security reforms

This paper examines some current reforms to social security benefits / tax credits and changes to employment provisions from a gender perspective. It analyses tensions between the trend towards ‘individualisation’ and growing emphasis on the couple/household as a policy focus. New tax credits change the distribution of resources within many couples. Incentives to work for some second earners should improve; but extending in‐work subsidies to childless couples raises questions. Payment of child tax credit to the ‘main carer’ has been welcomed, though the implications of joint ownership of tax credits are unclear, and joint assessment will be extended. Many claimants' partners can now access employment services. However, this is aimed at reducing the number of workless households rather than expanding individuals' opportunities. Joint claims for jobseeker's allowance, and work‐focused interviews, involve increased responsibilities for partners but no right of access to individual income. A more consistent critical analysis of reform from a gender perspective is required.

The Incidence of Accounting-based Covenants in UK Public Debt Contracts: An Empirical Analysis

Accounting-based covenants are of particular interest to accounting researchers in view of their potential to influence management's accounting policy choices and their attitudes to new accounting standards. This exploratory paper provides evidence on the incidence of accounting-based covenants in 108 UK public debt contracts for the period 1987-1990. Thirty percent of the agreements contain such covenants, the majority of which are affirmative gearing covenants. Focusing on the institutional differences between the UK and the US, the paper examines relationships between the presence of accounting-based covenants and (a) characteristics of the issuing firm, and (b) other control mechanisms included in the debt agreement. UK firms raising public debt are of good credit quality and UK insolvency procedures afford unambiguous protection to secured creditors. As a result, accounting-based covenants are associated with long-term unsecured debt and with firms having high values for assets-in-place but, in contrast with US findings, are unrelated to gearing. Convertibility appears to reduce the need for accounting-based covenants, especially when the debt is also subordinated. The relationship between accounting- based covenants and security depends on the nature of the security (fixed or floating). Longer term non-convertible debt agreements are, therefore, particularly likely to contain covenants that could influence management's accounting behaviour. This paper provides a starting point for further research into these issues.

Modigliani and Miller Again Revisited: The Cost of Capital with Unequal Borrowing and Lending Rates

The financial literature asserts that financial managers must borrow at least to some degree if they are to optimise the value of their companies. This result has been described in the literature as ‘perhaps the single most important result in the theory of corporate finance obtained in the last 30 years’ (Copeland and Weston, 1988, p. 443). Based on US tax systems, the value added to a company by debt has been estimated as high as 35 to 50% of the debt's market value. More recently in this journal, Ashton (1989b) has argued that under the present UK tax system, the theoretical tax advantage afforded by debt should be estimated at no more than 13% of the debt's market value. The contribution of this paper is to draw attention to an aspect of borrowing that has largely escaped attention, but which nevertheless affects the above conclusions: namely, that the market spread between borrowing and lending constitutes a ‘cost’ for corporate borrowing. This paper demonstrates that in the context of the present UK tax system, this ‘cost’ of borrowing is sufficient to nullify entirely the formerly perceived financial tax benefits of corporate borrowing. We conclude that, at present, corporate borrowing could imply a net disadvantage for the valuation of a company's equity by about 6 or 7% of the debt's market value.     

Corporate Social Performance and Stock Returns: UK Evidence from Disaggregate Measures

This study examines the relation between corporate social performance and stock returns in the UK. We closely evaluate the interactions between social and financial performance with a set of disaggregated social performance indicators for environment, employment, and community activities instead of using an aggregate measure. While scores on a composite social performance indicator are negatively related to stock returns, we find the poor financial reward offered by such firms is attributable to their good social performance on the environment and, to a lesser extent, the community aspects. Considerable abnormal returns are available from holding a portfolio of the socially least desirable stocks. These relationships between social and financial performance can be rationalized by multi-factor models for explaining the cross-sectional variation in returns, but not by industry effects.
