Risky Earnings, Taxation and Entrepreneurial Choice: A Microeconometric Model for Germany

Which role do individual income prospects play in the decision to be an entrepreneur rather than an employee? In a model of occupational choice, higher expected after-tax earnings attract people to self-employment, while more risky net earnings deter risk-averse individuals. In this paper I analyse the expected value and variance of income in self-employment and dependent employment empirically, accounting for selection. Based on this analysis, structural models of self-employment entry and exit under risk are estimated, which include a standard risk aversion parameter. The model predicts that the German income tax reduction of 2000 induced smaller exit rates out of self-employment for men and smaller entry rates for women.Entrepreneurship, risk, returns to self-employment, taxation

Personal Bankruptcy Law, Wealth and Entrepreneurship: Theory and Evidence from the Introduction of a "Fresh Start"

A personal bankruptcy law that allows for a "fresh start" after bankruptcy reduces the individual risk involved in entrepreneurial activity. On the other hand, as risk shifts to creditors who recover less of their credit after a debtor's bankruptcy, lenders may charge higher interest rates or ration credit supply, which can hamper entrepreneurship. Both aspects of a more forgiving personal bankruptcy law are less relevant for wealthy potential entrepreneurs who still risk losing their wealth, but tend not to face higher interest rates because they provide collateral. This paper illustrates these effects in a model and tests the hypotheses derived by exploiting the introduction of a "fresh start" policy in Germany in 1999 as a natural experiment, based on representative household panel data. The results indicate that the insurance effect of a more forgiving personal bankruptcy law exceeds the interest effect and on balance encourages less wealthy individuals to enter into entrepreneurship.Personal bankruptcy law, insolvency, entrepreneurship, fresh start

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

When possible income tax reforms are debated, the suspected impact on entrepreneurship is often used as an argument in favour or against a certain policy. Quantitative ex-ante evaluations of the effect of certain tax reform options on entrepreneurship based on microeconometric research have not been provided by the literature, however. This paper estimates the ex-ante effects of the German tax reform 2000 and of two hypothetical flat tax scenarios on entries into and exits out of self-employment in Germany. For the estimation I apply a microsimulation model which is based on the tax-benefit model STSM and on structural microeconometric models of transitions into and out of self-employment. These structural models include an estimated parameter of risk aversion. The simulation results indicate that flatter tax systems do not encourage, but rather discourage people from choosing self-employment. This is explained by the reduction of entrepreneurs' income risk through progressive taxation.Entrepreneurship, income taxation, risk, tax reform 2000, flat tax

How Should Local Governments Tax Local Business?: Lessons from an International Comparison and a Microsimulation Analysis for Germany

The local business tax as the main revenue source of local governments in Germany has been under extensive debate for decades. Proposals for reform range from a broad tax base in the sense of an origin-based value-added tax to a pure profit tax that could be implemented as a surcharge on corporation and personal income tax. Local business taxation systems in OECD countries actually represent the whole spectrum between these two extremes. We use a newly developed microsimulation model for the business sector in Germany to analyse the fiscal and distributional effects of the general reform options identified, including the extension of the local business tax to liberal professionals. We also analyse the effects of the actual German business tax reform 2008 with respect to local business tax revenues.Local business tax, microsimulation, local taxation, tax reform

Differential Taxation and Firms' Financial Leverage: Evidence from the Introduction of a Flat Tax on Interest Income

Tax competition for the mobile factor capital has led to a trend in many countries to levy lower taxes on interest income, often introducing differential taxation between interest and business income. In this study, we analyze the effect of such differential taxation on the debt ratio of firms. We exploit a 2009 tax reform in Germany as a quasi-experiment, which introduced a flat final withholding tax and opened a gap of 18 percentage points between the tax rate on income from unincorporated businesses and the new lower tax rate on interest income. We apply a regression adjusted semi-parametric difference-in-difference matching strategy based on firm level panel data. In addition, we implement a more structural approach with a tax rate differential, taking into account its endogeneity by using instrumental variables. The results indicate that firms increase their leverage when the tax rate on interest income decreases, albeit to a small degree.Income taxation, capital taxation, financial structure, leverage, matching

Expected Future Earnings, Taxation, and University Enrollment: A Microeconometric Model with Uncertainty

Taxation changes the expectations of prospective university students about their future level and uncertainty of after-tax income. To estimate the impact of taxes on university enrollment, we develop and estimate a structural microeconometric model, in which a high-school graduate decides to enter university studies if expected lifetime utility from this choice is greater than that anticipated from starting to work right away. We estimate the ex-ante future paths of the expectation and variance of net income for German high-school graduates, using only information available to those graduates at the time of the enrollment decision, accounting for multiple nonrandom selection and employing a microsimulation model to account for taxation. In addition to income uncertainty, the enrollment model takes into account university dropout and unemployment risks, as well as potential credit constraints. The estimation results are consistent with expectations. First, higher risk-adjusted returns to an academic education increase the probability of university enrollment. Second, high-school graduates are moderately risk averse, as indicated by the Arrow-Pratt coefficient of risk aversion estimated within the model. Thus, higher uncertainty among academics decreases enrollment rates. A simulation based on the estimated structural model indicates that a revenue-neutral, flat-rate tax reform with an unchanged basic tax allowance would increase enrollment rates for men in Germany because of the higher expected net income in the higher income range.University Enrollment, Income Taxation, Flat Tax, Income Risk, Risk Aversion

Income Taxes and Entrepreneurial Choice: Empirical Evidence from Germany

Entrepreneurial activity is often regarded as an engine for economic growth and job creation. Through tax policy, governments possess a potential lever to influence the decisions of economic agents to start and close small businesses. In Germany, the top marginal income tax rates were reduced exclusively for entrepreneurs in 1994 and 1999/2000. These tax reforms provided two naturally defined control groups that enable us to exploit the legislation changes as "natural experiments". First, the tax rate reductions did not apply to freelance professionals (Freiberufler), and second, entrepreneurs with earnings below a certain threshold were not affected. Using data from two different sources, the SOEP and the Mikrozensus (LFS), we analyse the effect of the tax cuts on transitions into and out of self-employment and on the rate of self-employment. We apply a "difference-in-difference-in-difference" estimation technique within a discrete time hazard rate model. The results indicate that the decrease in tax rates did not have a significant effect on the self-employment decision.Taxation, entrepreneurship, natural experiment, difference-in-difference-in-difference estimation
