We study government interventions in a dynamic market with asymmetric information. We show that restricting trading opportunities after an initial round of trade is always optimal. Under a suffi cient condition it is optimal to subsidize trades only at time zero while imposing prohibitively high taxes afterwards. If interventions are required to generate a Pareto improvement over laissez-faire ...

I believe that no argument is needed to convince the readers that the so-called “hard determinism,” which rules out free will, and hence also independent personal choice, is incompatible with PEL. On the other hand, the “soft” variety of determinism, known under the name “compatibilism,” is oftentimes claimed to be reconcilable with PEL. According to compatibilism, the assumption that every eve...

This paper introduces endogenous and directed technical change in a growth model with environmental constraints. The final good is produced from "dirty" and "clean" inputs. We show that: (i) when inputs are sufficiently substitutable, sustainable growth can be achieved with temporary taxes/subsidies that redirect innovation toward clean inputs; (ii) optimal policy involves both "carbon taxes" a...

This research stream uses neuroscience approaches to study information modeling constructs. Information modeling models the problem domains to facilitate understanding and communication during the information systems development process. Accurate representation and interpretation of the information models are vital to the success of information systems projects. The building blocks of informati...

We use a simple framework where firms in two countries serve their respective domestic markets and a world market to analyze under which conditions cost-reducing mergers will be beneficial for the merging firms, the home country, and the world as a whole. For a national merger, the policies enacted by a national merger authority tend to be overly restrictive from a global efficiency perspective...

The paper examines the allocation of macroeconomic risks a stochastic growth model with overlapping generations. For several standard models with CRRA preferences, I find laissez faire ex ante inefficient in the direction of imposing too little productivity risk on the old and too much risk on the young and on future generations. Governments commonly issue safe debt and promise safe public pens...

triple helix model (th) collaborations involving university, industry and government provide a networked infrastructure for shaping the dynamic fluxes of knowledge base of innovations locally and these fluxes remain emergent within the domains. in this article first the knowledge-based economy, national system of innovation, and three models of uig relations which represent different triple hel...

the aim of this study was to examine the effect of new methods of management on creativity, self-efficiency and mobility of human resources in sport organizations. all top managers and heads of sport and youth office (sports bodies) in the province participated in this study. 37 top managers and 176 presidents and vice presidents of sports bodies were randomly selected as the sample. the multi-...
