In most instances of collective decision-making, it cannot be expected that all persons who are entitled to vote will end up doing so. This has led institutional designers, out of concerns with the “legitimacy” of decisions, to introduce quorum requirements. A prominent example of this can...

Carbon price is a key variable in management and risk decisions in activities related to the burning of fossil fuels. Using innovative multivariate wavelet analysis, we study the link between carbon prices and primary and final energy prices in the time and frequency dimensions, particularly in...

We assess U.S. monetary policy across time and frequencies in the framework of the Taylor Rule (TR). First, we portray the deviations between policy interest rates and the TR-prescribed rates with a set of continuous wavelet tools, comprising the coherency, phase-diference and gain. Then, using...

We use wavelet analysis to study the impact of the Euro adoption on the oil price macroeconomy relation in the Euroland. We uncover evidence that the oil-macroeconomy relation changed in the past decades. We show that after the Euro adoption some countries became more similar with respect to how...

A large body of empirical literature has suggested that oil price shocks have an important effect on economic activity. But in most of the literature the analysis is exclusively done in the time domain. However, interesting relations exist at different frequencies. We use (cross) wavelet...

Economic agents simultaneously operate at different horizons. Many economic processes are the result of the actions of several agents with different term objectives. Therefore, economic time-series is a combination of components operating on different frequencies. Several questions about the...

This study looks into the factors that explain foreign direct investment in Brazil by country of origin of investment. Based on a sample of more than 100 countries that invested and have not yet invested in Brazil, multiple estimation techniques, such as the Tobit, Heckit and Probit, are used to...

We show that dependence of production on foreign inputs (or non-producible natural resources) can significantly increase the likelihood of indeterminacy. Payment of imported foreign factors of production may act as a semi-fixed cost, amplifying production externalities and returns to scale,...

I present an overlapping generations model, with formal education as the engine of growth, close to Glomm and RaviKumar (1992). Contrary to Glomm and Ravikumar, I Show that public schooling, when compared to a private system, may stimulate economic growth.

This paper provides new empirical evidence on and theoretical support for the close link between oil prices and aggregate macroeconomic performence in the 1970s. Although this link has been well documented in the empirical literature and is further confirmed in this paper, standard economic...
