Dynamic Volatility Connectedness among Cryptocurrencies: Evidence from Time-Frequency Connectedness Networks

نویسندگان

چکیده

This study examines the time-varying connectedness among realized volatilities of seven major cryptocurrencies between January 2020 and May 2022. To this end, we implement time frequency parameter vector autoregression (TVP-VAR) approaches. Our findings propose that (i) COVID-19 pandemic significantly affected dynamic connectedness; (ii) total index hits its apex around official announcement pandemic; (iii) in line with previous studies Ethereum, Bitcoin, Link are largest propagators/recipients shocks; (iv) tightest volatility interdependencies related to short-run.

Political Connectedness and Firm Performance: Evidence From Germany

This paper investigates politically connected firms in Germany. With the introduction of a new transparency law in 2007, information on additional income sources for all members of the German parliament became publicly available. We find that members of the conservative party (CDU/CSU) and the liberal party (FDP) are more likely to work for firms than members of left-wing parties (SPD and The L...

Detecting connectedness.

Natural visual images are typically composed of multiple objects, which need to be segregated from each other and from the background. The visual system has evolved to capture a great variety of cues that allow a meaningful segmentation of the visual input. One of these cues is connectedness. Connected image regions are likely to belong to a single visual object, whereas disconnected image regi...

Uniform connectedness and uniform local connectedness for lattice-valued uniform convergence spaces

We apply Preuss' concept of $mbbe$-connectedness to the categories of lattice-valued uniform convergence spaces and of lattice-valued uniform spaces. A space is uniformly $mbbe$-connected if the only uniformly continuous mappings from the space to a space in the class $mbbe$ are the constant mappings. We develop the basic theory for $mbbe$-connected sets, including the product theorem. Furtherm...

Coronary Segmentation from Echocardiography using Fuzzy Connectedness

In this paper we study the segmentation of coronary arteries from bidimensional echocardiography simulated images (phantoms) using Fuzzy Connectedness concepts implemented using Image Foresting Transform (IFT). This approach transforms the image into an oriented and weighted graph; therewith a graph-based algorithm can be applied to process the image segmentation. In echocardiographic scenario,...

Connectedness in graph limits

We define direct sums and a corresponding notion of con-nectedness for graph limits. Every graph limit has a unique decomposition as a direct sum of connected components. As is well-known, graph limits may be represented by symmetric functions on a probability space; there are natural definitions of direct sums and connectedness for such functions, and there is a perfect correspondence with the...
