Corporate Rights to Free Speech?

Although the courts have ruled that companies are legal persons, they have not yet made clear the extent to which political free speech for corporations is limited by the strictures legitimately placed upon corporate commercial speech. I explore the question of whether or not companies can properly be said to have the right to civil free speech or whether corporate speech is always de facto commercial speech not subject to the same sorts of legal protections as is the right to civil free speech. In the absence of clearly defined legal precedent, I emphasize moral reasons for determining the appropriate limits of corporate civil free speech. Appealing to arguments typically used to justify individual rights to civil free speech, I examine the extent to which this sort of justification may or may not be legitimately extended to corporations. I conclude that corporate rights to civil free speech must be restricted because granting rights of free speech to institutions may, in practice, undermine the moral rationale and practical feasibility of guaranteeing rights of civil free speech to individuals. Furthermore, I argue that granting corporations full rights to civil free speech will undercut attempts to develop good moral character in corporate institutions by undermining the efforts of watchdog organizations.     

Prices and factor demand in an endogenized input–output model

This paper combines factor demand functions (for intermediate input and labour) and price equations (derived from a Generalized Leontief cost function) with the traditional input–output price model. The cost functions determine factor demands for materials and labour as well as output prices at given input prices. At the second level of aggregation, the intermediate demand as a single input is split proportional to the elements in the column of the technical coefficients matrix. The emphasis in this endogenization of technical coefficients is on two features. First, the repercussion of output on input prices, and, second, the link between the econometric model for the supply side and the input–output demand model.
