This paper examines the welfare effects of anti-sprawl policies, such as development tax, in a simple spatial explicit urban model with two market failures - urban decline at the city core and underprovision of open space amenities at the urban fringe - and pre-existing distortionary property tax, used to fund public services and improvements to mitigate urban decline. Consistent with prior double-dividend literature, there is a tax interaction effect that occurs between the development tax and the pre-existing property tax. However, there are two fundamental differences between the tax interaction effect identified here and that of prior literature. Ours one has two components: First, there is a cost-side tax interaction effect that is 'spatially' concentrated at the urban fringe, as only agents at the urban fringe alter their behavior in response to the development tax. Second, there is also a benefit-side tax interaction effect, as increases in open space at the urban fringe are capitalized into housing prices throughout the city. In contrast to prior literature, we find that the empirical importance of the combined tax interaction effect is of substantially less importance and, as a consequence, the likelihood of a 'double-dividend' is higher than in prior studies. Further, we show that the development tax should be part of the local tax system, even in the absence of open space benefits. © 2010 Elsevier Inc.

This paper investigates the consumption of sugar cane ethanol in Brazil for the time period from January 2000 to December 2012. We examine ethanol and gasoline consumption along with the price ratio series. Two important features of the data are analyzed, in particular, its degree of persistence and the seasonality. The results show that the two series of consumption are fractionally integrated with orders of integration smaller than 1 implying that shocks in the series will disappear in the long run. On the other hand, the price ratio series displays an order of integration higher than 1 implying lack of mean reversion behavior. This suggests that strong policy measures must be adopted on prices in the event of shocks since they do not recover by themselves in the long run. © 2014 Elsevier Ltd.

China has been experiencing a historical take-off in its use of intellectual property rights (IPR). This paper discusses the IPR strategy of two leading high-tech Chinese firms, Huawei and ZTE, analyzing how they are moving to global leadership in the telecom equipment market. Specifically, the paper addresses their IPR performance with respect to patenting and trademark registration in the most relevant global IPR systems. By 2008 Huawei had already reached world leadership in the international PCT patents applicants' ranking, while in 2011 Huawei was substituted by ZTE in that position (with Huawei dropping to 3rd place). The paper shows how both firms have developed dynamic capabilities in innovation by investing strongly in R&D. This investment has reflected in a dramatic growth of patent applications. Even if a direct correlation between patent applications and capacity to innovate is not assumed, the growing demand for patents (and more recently trademarks) in different IPR systems reveals an aggressive technological and commercial stance of both firms on the global market. © 2013 PICMET.

This paper investigates paths for improving efficiency in the Brazilian motor carrier industry, which has undergone significant transformations since the economy deregulation in the mid 1990s. The main research objective is to determine whether or not different types of cargoes and geographic regions serviced significantly impact trucking efficiency levels by applying a Distance Friction Minimization approach with fixed factors. Results support the evidence regarding a heterogeneous impact of cargo mix and route mix on input reducing and output increasing potentials. Managerial impacts in terms of fleet subcontracting and increased focus on specific transport demands are also addressed. © 2014 Elsevier Ltd. All rights reserved.

We use a spatial Probit model to study the effect of contagion between banking systems of different countries. Applied to the late 1990s banking crisis in Asia we show that the phenomena of contagion is better seized using a spatial than a traditional Probit model. Unlike the latter, the spatial Probit model allows one to consider the cascade of cross and feedback effects of contagion that result from the outbreak of one initial crisis in one country or system. These contagion effects may result either from business connections between institutions of different countries or from institutional similarities between banking systems. © 2014 Elsevier B.V.
