Is self-employment really a bad experience? : The effects of previous self-employment on subsequent wage-employment wages

We use propensity score matching methods to quantify the effects of past self-employment experience on subsequent earnings in dependent employment using data on the population of Danish men observed between 1990 and 1996. Our results generally confirm existing studies in that we find that a spell of self-employment is associated with lower hourly wages compared to workers who were consecutively wage-employed. We also show, however, that this effect disappears—and even becomes positive in some settings—for formerly self-employed who find dependent employment in the same sector as their self-employment sector. Hence, the on average negative effect of self-employment is rather caused by sector switching than by the self-employment experience per se. Moreover, formerly self-employed who either enjoyed a high income or hired at least one worker during their self-employment spell receive wages in subsequent dependent employment that are at least as high as for individuals who have been consecutively wage-employed.     

Do Immigrants Affect Firm‐Specific Wages?*

We propose and test a novel effect of immigration on wages. Existing studies have focused on the wage effects that result from changes in the aggregate labour supply in a competitive labour market. We argue that if labour markets are not fully competitive, immigrants might also affect wage formation at the most disaggregate level – the workplace. Using linked employer?employee data, we find that an increased use of low‐skilled immigrant workers has a significantly negative effect on the wages of native workers at the workplace – also when controlling for potential endogeneity of the immigrant share using both fixed effects and instrumental variables.     

Interaction effects between dynamic hybrid products and traditional deferred annuities in the German life insurance market

Financial Markets and Portfolio Management - Dynamic hybrid products emerged in 2007 and are now well established in the German life insurance market. In this article, we study interaction effects...     

Labour market institutions,learning and self-employment

We develop a dynamic partial-equilibrium model to analyse how labour market institutions (wage compression, minimum wages, unemployment benefits, mobility costs and fixed-costs of self-employment) and learning affect who and when people become self-employed. We find that certain ability groups of workers become self-employed for both “carrot” and “stick” reasons: Some prefer self-employment to the low institutionalised wage, while others are not productive enough to qualify for a job at the institutionalised wage. Furthermore, wage compression and learning may give rise to a class of switchers who start in wage employment and later switch to self-employment. Several predictions of the model are consistent with observed empirical regularities, such as the existence of a group of low-skilled self-employed workers, the increasing propensity for self-employment over age groups and the larger spread in earnings among self-employed.     

Attitudes towards immigration—Perceived consequences and economic self-interest

Using the European Social Survey 2002/3, we develop a new test of whether economic self-interest influences people's attitudes towards immigration, exploiting that people have widely different perceptions of the consequences of immigration.     

Do Foreign Experts Increase the Productivity of Domestic Firms?

While most countries welcome (and some even subsidize) high‐skilled immigrants, there is very limited evidence of their importance for domestic firms. To guide our empirical analysis, we first set up a simple theoretical model to show how foreign experts can affect the productivity and wages of domestic firms. Using matched worker–firm data from Denmark and a matching difference‐in‐differences approach, we then find that firms that hire foreign experts instead of domestic experts become more productive, in the sense that they pay higher wages to high‐skilled co‐workers.     

Investment liberalisation and firm selection process: A welfare analysis from a host-country perspective

We set up a theoretical model to analyze the implications of coordination of immigration policies among destination countries. The model contains two types of spillovers between destination countries: a terms-of-trade externality and a welfare-policy externality. We show that while coordination unambiguously increases welfare of the destination countries, the effects on the level of immigration and on the income distribution of natives are ambiguous. Thus, coordination among destination countries does not necessarily solve the global coordination problem of inoptimally low levels of migration.     

Strategic interaction in undeveloped credit markets

This paper studies the strategic interaction between informal and formal lenders in undeveloped credit markets. In a model with adverse selection, loan seniority, market power, and differences in the cost of lending, it is shown that under general conditions a co-funding equilibrium will be a Nash outcome of the game. We demonstrate that a collateral requirement in connection with formal loans always generates a new co-funding equilibrium in which both lenders earn higher profits. A government subsidy to the formal lender may have the opposite effect. We relate our results to existing empirical evidence and the emerging discussion of how to best ensure financial viability and outreach of microfinance institutions.     

Entrepreneurship,job creation and wage growth

This paper analyses the importance of entrepreneurs in terms of job creation and wage growth. Relying on unique data that cover all establishments, firms and individuals in the Danish private sector, we are able to distil a number of different subsets from the total set of new establishments—subsets which allow us to more precisely capture the “truly new” or “entrepreneurial” establishments than has been possible in previous studies. Using these data, we find that while new establishments in general account for one-third of the gross job creation in the economy, entrepreneurial establishments are responsible for around 25% of this, and thus only account for about 8% of total gross job creation in the economy. However, entrepreneurial establishments seem to generate more additional jobs than other new establishments in the years following entry. Finally, the jobs generated by entrepreneurial establishments are to a large extent low-wage jobs, as they are not found to contribute to the growth in average wages.
