We develop and implement methods for determining whether relaxing sparsity constraints on portfolios improves the investment opportunity set for risk-averse investors. We formulate a new estimation procedure for sparse second-order stochastic spannin

Abstract This paper aims to assess the level of implementation of Green Public Procurements (GPP) in the Region of Western Macedonia—Greece, which is currently under energy transition from lignite to a RES-based energy model. By that assessment, a

We develop and implement methods for determining whether introducing new securities or relaxing investment constraints improves the investment opportunity set for prospect investors. We formulate a new testing procedure for prospect spanning for two

We derive properties of the cdf of random variables defined as saddle-type points of real valued continuous stochastic processes. This facilitates the derivation of the first-order asymptotic properties of tests for stochastic spanning given some sto

PURPOSE: This paper examines to what extent the governance modes of transition in the region of Western Macedonia (Greece) are effective and just, and whether they embed transition management, spatial justice, and place-based elements. To this end, t

Carbon monoxide, XCO, and methane, XCH4, column-averaged dry-air mole fractions (DMFs), observed by the TROPOspheric Monitoring Instrument (TROPOMI) on board Sentinel-5P (S-5P), are validated against those obtained from a Bruker ground-based low-reso
