We study a model where some investors (“hedgers”) are bad at information processing, while others (“speculators”) have superior information-processing ability and trade purely to exploit it. The disclosure of financial information induces a trade externality: if speculators refrain from trading, hedgers do the same, depressing the asset price. Market transparency reinforces this mechanism, by making speculators’ trades more visible to hedgers. Hence, issuers will oppose both the disclosure of fundamentals and trading transparency. Issuers may either under- or over-provide information compared to the socially efficient level if speculators have more bargaining power than hedgers, while they never under-provide it otherwise. When hedgers have low financial literacy, forbidding their access to the market may be socially efficient.

Using a firm-level international panel data set, we study if unemployment insurance offered by the government and by firms are substitutes. We exploit cross-country and time-series variation in public unemployment insurance as a shifter of workers’ demand for insurance within firms, and family versus nonfamily ownership as a shifter of firms’ supply of insurance. Our evidence supports the substitutability hypothesis: employment stability in family firms is greater, and the wage discount larger, in countries and periods with less generous public unemployment insurance, whereas no such substitutability emerges for nonfamily firms.
