Pursuing consumer empowerment in the age of big data: A comprehensive regulatory framework for data brokers

Data brokers play a central role in the big data ecosystem, compiling personal data from numerous sources and subsequently selling them to businesses worldwide. Such practices, however, generally occur clandestinely without consumers' knowledge or consent and can harm consumers in a discriminatory manner. In recent years, US policymakers have been urged to regulate data brokers by promoting individual choice but have failed, whereas the European Union has introduced broad data privacy guarantees for consumers and a data protection regime that limits data brokers' activities if consumers' consent has not been obtained for specific purposes. Because of the power imbalance between consumers and data brokers, the author argues that the European Union's coherent data protection framework serves as an effective model for regulating data brokers.     

Demand for coffee in Sweden: The role of prices, preferences and market power

There is a widespread belief that consumer coffee prices are high relative to bean prices and that lower consumer prices would lead to substantial increases in bean exports from Third-World countries. This issue is evaluated by analysing how retail prices, preferences and market power influence coffee demand in Sweden. A demand function is estimated for the period 1968–2002 and used, together with information on import prices of coffee beans, to simulate an oligopoly model. This approach gives estimates of the maximum average degree of market power and shows how coffee demand would react to reductions in marginal cost to its minimum level. The maximum level of market power is found to be low, but it generates large spreads between consumer and bean prices because the price elasticity has low absolute values. Moreover, the impact of a price decrease would be small because long-run coffee demand is dominated by changes in the population structure in combination with different preferences across age groups. Hence, a change to perfect competition would only have a negligible effect on bean imports.
