This paper explores how discontinuities created by national borders can influence development across the Americas. We exploit the discontinuous nature of borders jointly with exogenous variation at the national level to identify discontinuous effects on proxies for economic development at the regional and pixel levels. We separate the effects of national institutions from local historical conditions. Our analysis yields three main findings. First, we find important discontinuities in development across national borders for the Americas.

With its fixation on equilibrium thinking and an exclusive focus on market factors that can be precisely measured, the neoclassical orthodoxy in economics is fundamentally unequipped to deal with today's biggest problems. Change within the discipline is underway, but it cannot come fast enough.

Pricing greenhouse-gas (GHG) emissions involves making tradeoffs between consumption today and unknown damages in the (distant) future. While decision making under risk and uncertainty is the forte of financial economics, important insights from pricing financial assets do not typically inform standard climate–economy models. Here, we introduce EZ-Climate, a simple recursive dynamic asset pricing model that allows for a calibration of the carbon dioxide (CO2) price path based on probabilistic assumptions around climate damages.

Being a successful manager or entrepreneur in the media and digital sector requires creativity, innovation, and performance. It also requires an understanding of the principles and tools of management. Aimed at the college market, this book is a short, foundational volume on media management. It summarizes the major dimensions of a business school curriculum and applies them to the entire media, media-tech, and digital sector. Its chapters cover—in a jargonless, non-technical way—the major functions of management.

As with previous technological revolutions, innovations in the online world have triggered transformations in the labor market and the economy. While the Internet is trumpeted as a great job creator, there are also downsides that need to be identified and dealt with. The book discusses the following topics:

Originally published in 1992 this book charts the global restructuring of telecommunications industries away from the monopoly structures of the past towards increased competition, deregulation and privatization. The book's authors are international policy-makers and scholars, who examine the regulatory environment within a theoretical and historical context. The book looks at the roots of regulatory and legislative changes by discussing individually the countries at the forefront of the revolution: the UK, France, Germany, Japan and the United States.

Geographic price discrimination is generally considered beneficial to firm profitability. Firms can extract higher rents by varying prices across markets to match consumers' preferences. This paper empirically demonstrates, however, that a firm may instead prefer a national pricing policy that fixes prices across geographic markets, foregoing the opportunity to customize prices. Under appropriate conditions, a national pricing policy helps avoid intense local competition due to targeted prices.

This paper offers a new theory of limit pricing. Incumbents from different markets or regions "compete" against one another, with each attempting to price in a manner that deflects entry into the others' markets. An entrant is imperfectly informed as to the incumbents' respective investments in cost reduction and seeks to enter markets in which incumbents have high costs. In a focal equilibrium, the entrant uses a simple "comparison strategy," in which it enters only the highest-priced markets, and incumbents engage in limit-pricing behavior.
