The purpose of this study is to examine how households opt for their loan’s duration when it comes to energy efficiency retrofits (EERs). The primary focus is on the time horizon that these types of EERs will provide benefits to the households.

This study examines the second wave of the largest EER support program in Greece in recent years. The authors exploit an idiosyncrasy of the support program which offered interest-free loans. The baseline sample of this study includes approximately 18,000 households awarded the support and opted for a loan. To provide robustness and complement the analysis, the authors also use data from 38,000 households that were awarded support from the first wave of the EER program.

This study finds that EER investments that are likely to deliver longer-term benefits, in the form of energy savings, are positively associated with longer duration. This finding implies that households view such EERs as long-term investments that will consistently provide benefits in the future, thereby tolerating a longer period of incurring the inconvenience of paying monthly installments.

This study posits that an EER can be perceived by the household as an investment that saves money in the long term because of more efficient energy use. To this end, the authors bring forward the duration of the benefits accrued to the household as a driving factor to the household’s decision over the length of the loan.

This study expands on prior literature that has focused on consumer and loans for durables (e.g. cars) by examining EERs. However, EERs are different, as they can save households money in future periods. In addition, house EERs are at the forefront of energy policies and the design of future support programs at the epicenter of several initiatives.

The authors argue that the patent term change introduced in Trade Related Aspects of Intellectual Property Rights (TRIPS) in the USA inadvertently offered a metric of self-valuation of patents at the time of filing, affirming the ability of Drugs and Chemical patents to offer greater R&D incentives than other technology fields. As renewals also offer a metric of self-valuation, the authors find that upon renewal Computer patents are found to offer greater R&D incentives than Drugs and Chemicals. The purpose of this paper is to inquire as to why Computer patents are considered as more valuable in the post grant period, even though they were not considered as valuable upon filing. The authors advance the idea that patents can increase in value if encompassed in a patent portfolio.

The authors employ the introduction of the TRIPS agreement in the USA. In order to facilitate the move to TRIPS, the USPTO (unexpectedly) allowed applicants who filed prior to June 8, 1995 a patent length that was equal to the maximum of two regimes. Therefore, applicants that filed before the deadline were given a possible small extension of their patent’s time length. The authors use this change and renewal data to infer firms’ self-valuation of patents. For this reason, the authors acquire information for all utility patents that were filed around June 8, 1995 data project.

The authors offer an additional explanation that is related to the increasingly commonplace build up of patent portfolios: patents can increase in value if encompassed in a portfolio. Such portfolios are bundles of patents whose means to an end lays in their strength in numbers. As Lanjouw and Schankerman (2004) note, when a patent is added to a portfolio the cost of defending a technology against infringement allegations decreases. To rephrase, a patent is regarded as the additional foot-soldier who aids the firm, arm-in-arm, in defending its technological territory and in fulfilling its strategic goal.

The originality stemming from the paper is that policy makers that aim to tackle patent proliferation should not focus their attention to individual patents. Instead, they should target policies toward patent portfolios, because they provide the means of endowing patents with the extra weight that makes filing and renewing irrelevant patents worthwhile.

In this work, the authors analyze the dynamic interdependencies between military expenditures and the real economy for the period 1970–2018, and the authors' approach allows for the existence of dominant economies in the system.

In this study, the authors employ a Network General Equilibrium GVAR (global vector autoregressive) model.

By accounting for the interconnection among the top twelve military spenders, the authors' findings show that China acts as a leader in the global military scene based on the respective centrality measures. Meanwhile, statistically significant deviations from equilibrium are observed in most of the economies' military expenses, when subjected to an unanticipated unit shock of other countries. Nonetheless, in the medium run, the shocks tend to die out and economies converge to an equilibrium position.

With the authors' methodology the authors are able to capture not only the effect of nearness on a country's military spending, as the past literature has documented, but also a country's defense and economic dependencies with other countries and how a unit's military expenses could shape the spending of the rest. Using state-to-the-art quantitative and econometric techniques, the authors provide robust and comprehensive analysis.
