Sex, Drugs, and Bitcoin: How Much Illegal Activity Is Financed Through Cryptocurrencies?

Abstract: Cryptocurrencies are among the largest unregulated markets in the world. We find that approximately one-quarter of bitcoin users are involved in illegal activity. We estimate that around $76 billion of illegal activity per year involves bitcoin (46% of bitcoin transactions), which is close to the scale of the US and European markets for illegal drugs. The illegal share of bitcoin activity declines with mainstream interest in bitcoin and with the emergence of more opaque cryptocurrencies. The techniques developed in this paper have applications in cryptocurrency surveillance. Our findings suggest that cryptocurrencies are transforming the black markets by enabling “black e-commerce.”

Is There Really a Foreign Ownership Wage Premium? Evidence from Matched Employer-Employee Data

Abstract: Numerous studies on firm-level data have reported higher average wages in foreign-owned firms than in domestically-owned firms. This, however, does not necessarily imply that the individual worker’s wage increase with foreign ownership. Using detailed matched employer-employee data on the entire Swedish private sector, we examine the effect of foreign ownership on individual wages, controlling for individual and firm heterogeneity as well as for possible selection bias in foreign acquisitions. We distinguish between foreign greenfields and takeovers and compare foreign owned firms with both domestic multinationals and local firms. Our results show a considerably smaller wage premium in foreign owned firms than what has been found in studies conducted at a more aggregate level. Moreover, foreign takeovers of Swedish firms tend to have no or even a negative effect on wages.

Corporate Performance, Board Structure and its Determinants in the Banking Industry

Abstract: We examine the relation between board structure (size and composition) and firm performance using a sample of banking firms during 1959-1999. Contrary to the evidence for non-financial firms, we find that banking firms with larger boards do not underperform their peers in terms of Tobin's Q. We argue that M&A activity and features of the bank holding company organizational form may make a larger board more desirable for these firms and document that board size is significantly related to characteristics of our sample firms' structures. Even after accounting for these potential sources of endogeneity, we do not find a negative relationship between board size and Tobin's Q. Our findings suggest that constraints on board size in the banking industry may be counter-productive.
