This study applies the Dynamic Slacks Based Model (DSBM) developed by Tone and Tsutsui (2010) in order to assess the evolution of input saving/output increasing potentials in major Brazilian Banks from 1996 to 2011. We propose that these potentials or slacks can be used as proxies for an...

This paper analyses airline accidents data from 1927-2006. The fractional integration methodology is adopted. It is shown that airline accidents are persistent and (fractionally) cointegrated with airline traffic. Thus, there exists an equilibrium relation between air accidents and airline...

This paper assesses different measures of Tobin's <italic>q</italic> on the US labor market over 1948--2002. We find a negative long-run relationship between the unemployment rate and Tobin's <italic>q</italic>, which is consistent with capital and labor being complements in production.

One of the main goals of terrorism is to instill fear in a targeted populace. We investigate how information precision about rare, but highly devastating terrorist attacks influences psychological resilience, which we operationalize as the ability to continue to take optimum risks. First, we...

This paper models a dynamic scholar’s allocation of time between academia and professional activities outside academia, given the academic labor market and social interactions. The model shows how particularly in less developed countries business and political networks may have large negative...

This paper makes two contributions to the literature on terrorism: 1) It presents a model that explains the cyclical characteristics of terrorist attacks, and 2) It improves on the existing theoretical cyclical models since it takes explicitly into account terrorists' motivations and...

Evidence from five general-interest journals in economics reveals an inverse relationship between author seniority and the number of colleagues whom authors choose to thank and acknowledge. The large seniority effect is insensitive to the inclusion of controls for the number of co-authors,...

This paper considers the search for the best papers by the editors of an academic journal. At each period, each editor receives a set of submissions and has to decide which paper to accept. Some editors being more demanding than others, researchers choose the quality level of their papers taking...

The paper tests the hypothesis that the presence of indexed money may rule out a process of currency substitution in contexts of persistent high inflation. Estimates for the case of Brazil using monthly data for the period 1985 to 1993 and cointegration techniques offer support for that.
