When a survey response mechanism depends on the variable of interest measured within the same survey and observed for only part of the sample, the situation is one of nonignorable nonresponse. Ignoring the nonresponse is likely to generate significant bias in the estimates. To solve this, one...

Given the key role of the taxable income elasticity in designing an optimal tax system there are many studies attempting to estimate this elasticity. A problem with most of these studies is that strong functional form assumptions are used and that heterogeneity in preferences is not allowed for....

Using a sample of 96 mergers notified to the EU Commission and logit regression techniques, we analyse the Commission's decision process. We find that the probability of a phase 2 investigation and of a prohibition of the merger increases with the parties' market shares. The probability...

”Svensk arbetsmarknad tycks trotsa tyngdlagen.” Så uttalade sig finansminister Anders Borg i början av juli 2010. Han pekade på att det dramatiska fallet i BNP i finanskrisens spår inte hade åtföljts av någon dramatisk minskning av sysselsättningen. I denna uppsats ges en...

The paper offers a theoretical analysis of a labor market institution known as the Gent system, which is a system where unions run unemployment insurance (UI) through government-subsidized UI funds. This sytem is practiced in four Nordic countries with comparatively very high unionization rates....

This paper analyzes the design of optimal unemployment insurance in a search equilibrium framework where search effort among the unemployed is not perfectly observable. We examine to what extent the optimal policy involves monitoring of search effort and benefit sanctions if observed search is...

Existing unemployment insurance systems in many OECD countries involve a ceiling on insurable earnings. The result is lower replacement rate for employees with relatively high earnings. This paper examines whether replacement rates should decrease as the level of earnings rises. The framework is...

A Hallmark of modern labor conomics is the close interplay between the development of theory, data sources and econometric testing. The evolution of the economic analysis of unemployment insurance provides a good illustration. New Theoretical approaches, in particular job-search theory; have...

The probability of income loss depends on talent and effort. Effort has positive externalities and therefore individuals are awarded status in proportion to their perceived diligence. The social norm requires more effort from individuals perceived as more talented. But talent is private...

The paper develops an equilibrium search and matching model where two-person families as well as singles participate in the labor market. We show that equilibrium entails wage dispersion among equally productive risk-averse workers. Marital status as well as spousal labor market status matter...
