Radio spectrum is a vital asset and resource for mobile network operators. With spectrum in the 800 and 900 MHz bands coverage can be provided with fewer base station sites compared to higher frequency bands like 2.1 and 2.6 GHz. With more spectrum, i.e. wider bandwidth, operators can offer...

This paper examines the influence of a firm’s business model on the relative persistence of profit margins in the U.S. airline industry. The strategic management literature describes a firm’s business model as reflecting how that firm chooses to compete in the marketplace. Given this linkage...

I examine whether local bank finance facilitated the transition to a service-based economy in the U.S. I identify a causal role for local finance in service job creation. I use county-level changes to alcohol laws as demand shocks to service employers across a subsample of U.S. counties....

As a first step towards understanding the evolution of small groups in firms, this paper develops and tests a simple decision-theoretical model of research-unit evolution in which, as managers resolve their uncertainty over time, they shut down under-performing units and remove under-performing...

This paper investigates an asymmetric duopoly model with a Hotelling line. We find that helping a small (minor) firm can reduce both social and consumer surplus. This makes a sharp contrast to existing works showing that helping minor firms can reduce social surplus but always improves consumer...

US State governments invest in early-stage innovative activity as an economic development strategy. Nevertheless, attention directed at the public sector's role in this capacity has been placed on federal policy actions overlooking the growing role of states. The primary aims of this paper are...

The Organization of Economic Cooperation and Development (OECD) has in recent years devoted considerable resources to the study of productivity trends in the OECD area. In this article, Dirk Pilat, a senior economist at the OECD provides an overview of the key results of this research effort....

This paper studies how network structure can affect the speed of adoption. In particular, we model the decision to adopt Python 3 by software packages. Python 3 provides advanced features but is not backward compatible with Python 2, which implies adoption costs. Moreover, packages form...

Union membership in the United States displayed a ∩-shaped pattern over the 20th century, while income inequality sketched a ∪. A model of unions is developed to analyze these facts. There is a distribution of productivity across firms in the economy. Firms hire capital, plus skilled and...
