Among the benefits that technology can provide is greater connectivity among economic agents. Commerce now occurs across great geographic distances at nominal transaction costs. Technology, therefore, seems to have the potential to unshackle economic agents from their suppliers and customers,...

The desirability of airport congestion pricing largely depends on whether dominant airlines otherwise fail to internalize their self-imposed congestion delays. Brueckner (2002) and Mayer and Sinai (2003) find (weak) statistically significant evidence of internalization. We replicate and extend...

A reanalysis of the Hotz, McElroy, and Sanders research on the impact of a teen birth on socio-economic outcomes shows that their data set, which includes information on outcomes at older ages only for teen mothers with the earliest calendar year births, is partly responsible for their...

The aim of this paper is to test two related propositions: (1) that there is a direct, positive relationship between the involvement of a prolific inventor in the production of knowledge and the magnitudes in the collective dimension of this knowledge production, as measured by the presence of...

This paper studies an application of income-related patient cost-sharing. Using data from the Medicare Current Beneficiary Survey, we find that varying patient costsharing rates with patient income in the Medicare prescription drug program can reduce the severity of two problems: high...

I investigate differences in the effects of worker characteristics on wages in Panama at different points of the conditional wage distribution. Public sector employment increases wages of men and of women relatively more at lower quantiles. Public sector employment increases wages of the median...

A model of economic impacts of public gardens on their communities is developed stressing the roles of visitors as well as staff and suppliers in creating impacts. The model is implemented for four different gardens using a combination of survey and normal business data from the gardens with a...

I extend the Atkeson and Kehoe (1999) putty-clay model to include elastic labor supply and more general forms of technology to explore the impact of oil shocks on the macroeconomy. In particular, I am interested in (1) how this extension affects their results with regard to permanent changes in...

Some economic models like the cash-in-advance model of money have the property that the dynamical system characterizing equilibria is multi-valued going forward in time, but single-valued going backward in time, i.e., the model has backward dynamics. In this paper, we apply the theory of inverse...

A growing body empirical literature deals with persistence in innovation. However, there is neither a survey of the development and status of the field nor a clear statement of a theory of persistence which includes a formal model of the dynamics of firm persistence. This paper fills these gaps...
