This article studies the relationship between credit provision and stock trading behavior. We collect every stock transaction of the three major British companies during the 1720 South Sea Bubble and link stock trading to margin loan positions with the Bank of England. We give insights in the selection of traders into the loan facility by comparing the trading behavior and realized returns of borrowers to other traders. We find that loan holders are more likely to buy following high returns and document strong underperformance of borrowers.

The late Victorian era was characterized by close links between politicians and firms in the United Kingdom, with up to half of all members of Parliament serving as company directors. We analyze 467 British companies over the period 1895 to 1904. An analysis of election results shows that the election of a new tech director is associated with a 2 percent to 2.5 percent increase in that firm's share price, whereas old tech firms were unaffected by the electoral fortunes of their directors. New technology firms with political directors were more likely to undertake seasoned issues of both equity and debt.

When contracting, European merchants could at least partially observe characteristics such as the health, physical strength, and education of indentured servants. These characteristics, unobservable to us, were likely to influence servitude duration, which is observable to us. We employ a switching regression model to analyze 2,066 servitude contracts from the seventeenth and eighteenth centuries. Servants were positively selected to American mainland colonies in terms of their unobservable human capital and negatively selected to the West Indies. Thus, the relative quality of migrants' human capital may have played a role in the subsequent relative economic performance of these regions.
