Taking risky opportunities in youthful content creation: teenagers' use of social networking sites for intimacy, privacy and self-expression

Abstract: The explosion in social networking sites such as MySpace, Facebook, Bebo and Friendster is widely regarded as an exciting opportunity, especially for youth.Yet the public response tends to be one of puzzled dismay regarding a generation that, supposedly, has many friends but little sense of privacy and a narcissistic fascination with self-display. This article explores teenagers' practices of social networking in order to uncover the subtle connections between online opportunity and risk. While younger teenagers relish the opportunities to recreate continuously a highly-decorated, stylistically-elaborate identity, older teenagers favour a plain aesthetic that foregrounds their links to others, thus expressing a notion of identity lived through authentic relationships. The article further contrasts teenagers' graded conception of `friends' with the binary classification of social networking sites, this being one of several means by which online privacy is shaped and undermined by the affordances of these s...

Top Incomes in the Long Run of History

Abstract: A recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics. Top incomes represent a small share of the population but a very significant share of total income and total taxes paid. Hence, aggregate economic growth per capita and Gini inequality indexes are sensitive to excluding or including top incomes. We discuss the estimation methods and issues that arise when constructing top income share series, including income definition and comparability over time and across countries, tax avoidance, and tax evasion. We provide a summary of the key empirical findings. Most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks. Top income shares do not recover in the immediate postwar decades. However, over the last thirty years, top income shares have increased substantially in English speaking countries and in India and China but not in continental European countries or Japan. This increase is due in part to an unprecedented surge in top wage incomes. As a result, wage income comprises a larger fraction of top incomes than in the past. Finally, we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open.

Firms in international trade

Abstract: In discussing the origins and implications of international trade, economists usually emphasize comparative advantage, increasing returns to scale, and consumer love of variety, but pay relatively little attention to the firms that actually drive trade flows. Yet engaging in international trade is an exceedingly rare activity: of the 5.5 million firms operating in the United States in 2000, just 4 percent were exporters. Among these exporting firms, the top 10 percent accounted for 96 percent of total U.S. exports. Since the mid-1990s, a large number of empirical studies have provided a wealth of information about the important role thatfirms play in mediating countries’ imports and exports. This research, based on micro datasets that track countries’ production and trade at the firm level, demonstrates that trading firms differ substantially from firms that solely serve the domestic market. Across a wide range of countries and industries, exporters have been shown to be larger, more productive, more skill- and capital-intensive, and to pay higher wages than nonexportingfirms. Furthermore, these

An Economic Model of Representative Democracy

Abstract: This paper develops an approach to the study of democratic policy-making where politicians are selected by the people from those citizens who present themselves as candidates for public office. The approach has a number of attractive features. First, it is a conceptualization of a pure form of representative democracy in which government is by, as well as of, the people. Second, the model is analytically tractable, being able to handle multidimensional issue and policy spaces very naturally. Third, it provides a vehicle for answering normative questions about the performance of representative democracy.
