Iterative min-sum decoding of tail-biting codes
By invoking a form of the Perron-Frobenius theorem for the âmin-sumâ semi-ring, we obtain a union bound on the performance of iterative decoding of tail-biting codes. This bound shows that for the Gaussian channel, iterative decoding will be optimum, at least for high SNRs, if and only if the minimum âpseudo-distanceâ of the code is larger than the ordinary minimum distance
Trade Agreements as Endogenously Incomplete Contracts
We propose a model of trade agreements in which contracting is costly, and as a consequence the optimal agreement may be incomplete. In spite of its simplicity, the model yields rich predictions on the structure of the optimal trade agreement and how this depends on the fundamentals of the contracting environment. We argue that taking contracting costs explicitly into account can help explain a number of key features of real trade agreements.

Chicagoâs Shifting Attitude Toward Concentrations of Business Power (1934â1962)
The postwar Chicago School is commonly associated with a pro-corporate standpoint because of its position toward antitrust law and business monopoly. For example, starting in the 1950s, Aaron Directorâwho is often considered the father of Chicago law and economicsâand his students, such as John McGee, defended the practices of the Standard Oil Company, arguing that the Supreme Courtâs holding against the company in 1911 was erroneous. Since that time, Chicago has been associated with the position that competition has a self-correcting power, ensuring that monopoly power is short-lived.
Members of the Chicago School did not always take a pro-corporate position. In the 1930s, for example, the respected University of Chicago professor and self-identified classical liberal, Henry Simons, described monopoly in all its forms, including âgigantic corporationsâ and âother agencies for price control,â as âthe great enemy of democracy.â For Simons, concentrations of power undermined the necessary condition for democracy to flourish, namely, a competitive market. Besides Simons, Jacob Viner, the infamous Chicago price-theory guru and self-proclaimed classical liberal, also opposed concentrations of business power. Vinerâs views on business monopoly in the late 1930s can be gleaned from his correspondence with Laird Bell, a distinguished attorney and public benefactor of Chicago. In writing Bell, Viner acknowledged that big business had some benefits, but emphasized, â[T]he mere size of business units tends almost inevitably to result in attempts to escape the impact of competition which have importantâand in my opinion highly desirableâconsequences for the operation of the economic system.â Viner considered this to be âthe most important economic issue of our dayâ because ââbignessâ . . . is the essential element in the faulty working . . . of our economic system.â
This Essay traces the development of the Chicago Schoolâs changing position toward concentrations of business power. In Parts II and III, the Essay details the Chicago Schoolâs early position of broad hostility toward concentrations of business power and its belief that such concentrations of power needed to be eradicated by vigorous antitrust enforcement and radical corporate reform. Then, in Part IV, the Essay charts the Chicago Schoolâs shift during the Free Market Study toward a broad acceptance of concentrations of power and a position that large corporations and industrial monopoly were relatively benign. This Essay argues that the Chicago Schoolâs shift toward concentrations of power was a product of the postwar Chicago Schoolâs effort to reconstitute liberalism as a bulwark against collectivist challenges and increasing government regulation of business
