The economics of urban yard space: An “implicit-market” model for housing attributes

A theoretical housing model is developed embodying the approach of the recent hedonic price literature. Instead of focusing on a scalar “housing service” consumption measure, the model portrays housing as a commodity with two attributes: floor space and yard space. Developers react to a consumer bid-rent function, which relates dwelling rent to floor space, yard space, and location, in choosing the profit-maximizing characteristics of their housing complexes. The spatial behavior of the developer's choice variables is investigated (an interesting question is whether yards are larger farther from the urban center), and a comparative static analysis of the housing market equilibrium is presented.     

Critical factors in technological innovation and their policy implications

This paper explores the critical factors which affect the innovation proccess. Some ways in which some of these factors can be influenced by appropriate policy measures are discussed. In particular, the role of the federal government in promoting innovation is discussed.The role of the government in stimulating and nurturing the innovation process is a controversial one. Proponents of the free enterprise system, many of whom are spokespersons for various industries, have persistently pointed out the deleterious effects of regulation and control on the innovation process. By contrast, advocates of an activist government role are often able to cite the protection of the common welfare as a primary need for government intervention. In truth, the “government” is a patchwork of many governments, operating through many agencies and affecting firms and individuals at several levels and leverage points. The same regulation that has deleterious effects on Industry A may be a stimulus for innovation in Industry B. Even in Industry A, the regulation may act as a force in directing efforts toward certain types of R&D programs that would not otherwise be undertaken.In this paper we examine the specific instances where innovation projects, both product or process types, were affected by government regulation. We also briefly review the critical factors which affect the innovation process and how various governments in industrialized countries have taken actions to influence these factors. Finally, we examine some general guidelines for policymaking purposes.     

Labour Market Structure and Inequality: A Comparison of Italy and the U.S.

Markets with rigid labour regulations and centralized wage setting are often thought to be inefficient but egalitarian. Using a model of off-and on-the-job search and event-history, individual-level data for Italy and the U.S., we show that while the cross-sectional wage distributions of young Italian males are much more compressed than are the comparable distributions for young white U.S. males, the estimated search model implies that the distribution of lifetime welfare is no more disperse in the U.S. than it is in Italy. Our model implies that the high frequency of movements between labour market states leads to both a relatively equitable distribution of "long run" welfare in the U.S. and a high level of cross-sectional inequality.
