Most econometric studies of equity market integration suggest that national markets are increasingly becoming part of a global equity market. As regards the extent of this integration, however, the results are often inconclusive. Further analysis calls for a closer scrutiny of the basic...

The major strand of finance literature understands market efficiency through the market’s ability to process information into prices. Another strand of literature refers to the economists’ usual sense of the word, i.e. that markets ensure that resources are allocated to their most profitable...

By combining new data on bilateral asset holdings with data on securities regulation in an empirical gravity model, it is found that bilateral differences in securities regulation lead to decreased portfolio holdings. Hence, regulatory harmonization can foster financial integration. The results...

The achievements of social-welfare arrangements in Western Europe are well known: considerable income security, relatively little poverty and, in some countries, ample supply of social services. But there are also well-known weaknesses and hence considerable scope for improvement. Three types of...

It is useful to distinguish between exogenous and endogenous factors behind contemporary and expected future problems for the welfare state. This paper tries to identify major problems of both types and to indicate alternative reform possibilities to deal with them. At the same time as several...

The expansion of welfare-state arrangements is seen as the result of dynamic interaction between market behaviour and political behaviour, often with considerable time lags, sometimes generating either virtuous or vicious circles. Such interaction may also involve induced (endogenous) changes in...

We study sex trafficking in a marriage market model of prostitution. When traffickers can coerce women to sell sex, trafficked prostitutes constitute a non-zero share of supply in any unregulated market for sex. We ask if regulation can eradicate trafficking and restore the equilibrium that...

We construct a model in which a number of equally powerful ethnic groups compete for power by engaging in civil war. In non-redistributive equilibrium, ethnically homogeneous and ethnically diverse countries face a lower probability of civil war than countries with a moderate degree of ethnic...

Consulting firms (CFs) sell services on a project basis to many clients and must therefore continuously tender for new contracts. One frequently used strategy by CFs is to visit the clients in connection to the tenders. The reason to the visits is either: 1) to influence the client in his...
